VIDEO: Creating a Home COVID-19 Decontamination Area for the Clinician

Coronavirus (COVID-19) | May 29, 2020

Jay Mohan, D.O., RPVI, interventional cardiology fellow at William Beaumont Hospital, Royal Oak, Michigan, created this video. It shows other clinicians how he set up his home COVID-19 decontamination area where he changes clothes, shoes and sterilizes before entering his house in order to protect his family. He has been involved with direct care of COVID-19 patients the past two months.

Since the start of the SAR-CoV-2 pandemic, clinicians and first-responders who are in contact with, or possible contact with, COVID-19 patients have developed ways to not bring and viral contamination home with them. This often includes on transition spot in the garage or designed room where they can change out of work clothing and shoes and into new clothing and shoes. Shoes and coats are separated into ones used for home and those dedicated for use at work only. Those who wear and reuse N95 masks also have developed ways to take the mask off by the straps only so they do not touch it and strapping it over a tupperware container that can then be sealed, or stored inside a disposable paper or plastic bag.

Mohan is board certified in cardiology, internal medicine, echocardiography and nuclear cardiology. He also serves as vice president of the Dr. Ramesh Kumar Foundation

Mohan shares regular updates on Twitter about recent cardiology technology devices, takeaway points from conferences and short educational videos he produces. Follow or contact him via Twitter or Instagram at @cardiologyoncall.

Coronavirus (COVID-19) | May 07, 2020

Interview with Geoffrey Rose, M.D., president of Sanger Heart and Vascular Institute with Atrium Health, in Charlotte, North Carolina, and a board member with the American Society of Echocardiography (ASE). He explains the impact of COVID-19 (SARS-CoV-2) on the cardiovascular service line and cardiac imaging. He said the virus has led to use of computed tomography (CT) not only as the frontline cardiovascular imaging modality to evaluate chest pain, but also for COVID-19 pneumonia imaging.

Rose said cardiac ultrasound is still used, but requires full personal protective equipment (PPE) and often abbreviated exams because of the close proximity of the sonographer and patient when performing echocardiograms. This has given rise to using dedicated point-of-care ultrasound (POCUS) systems to answer specific clinical questions quickly. Smart-phone based POCUS systems that use an app and a transducer plugged into the phone enable basic echo exams or evaluation of other parts of the anatomy quickly without the need to immediately sterilize an entire cart-based ultrasound system. These small systems also can be completely enclosed inside a transducer sheath and the phone and single transducer are much easier and faster to wipe down. He said the quality of the exams are not as good as fully enabled echocardiography systems, but it allows for quick assessments of ejection fractions and to triage if the patient needs more advanced imaging if the basic questions cannot be answered.

Since hospitals have shut down now for about two months, postponing normal checkups, and elective exams and procedures, Rose said doctors still need to visit with patients who have chronic conditions. Sanger and Atrium Heath modified its ambulatory electronic medical record (EMR) and is using video conferencing to perform virtual appointments now for the majority of these patients. He said telemedicine was not widely used before COVID-19 in his hospital system, but the pandemic will likely alter the care model for the future, with more telemedicine visits being used even after epidemic is over. He said use of POCUS and CT as frontline cardiac imaging modalities will also likely remain in place after the pandemic because of the efficiencies in care these technologies offer.

Stephen Bloom, M.D., FASNC, director of nonivasive cardiology (cardiac CT, nuclear cardiology and echocardiography) at Midwest Heart and Vascular Associates, Overland Park, Kansas. He is also a member of the American Society of Nuclear Cardiology (ASNC) Board of Directors, explains some of the issues involved and protocols used for cardiac imaging during the COVID-19 pandemic. His discussion includes computed tomography, cardiac ultrasound and nuclear imaging.

Right now, Bloom said it is difficult to test everybody and there is a shortage of masks, gowns and other personal protective equipment (PPE), and the imaging equipment needs to be sanitized each time it is used. He said it is just is not possible to image all the patients who need imaging right now. Hospitals also are trying to limit the number of healthy people people coming into hospitals for routine visits and tests to reduce their potential exposure to the novel coronavirus (COVID-19, SARS-CoV-2) and help containment efforts. 

"The tests should be done, very simply, if it changes the care of the patient. If it doesn't change the care of the patient, and it can be postponed, it should be postponed," Bloom explained. "I would say 80 percent of our cardiac imaging exams have stopped. It has been very dramatic."

Hicham Skali, M.D., a staff cardiologist and member of the Non-invasive Cardiovascular Imaging Program at Brigham and Women’s Hospital (BWH), and at Brigham and Women’s / Massachusetts General Health Care Center at Foxborough, explains the new recommendations from the American Society of Nuclear Cardiology (ASNC) and from imagers in China and Singapore. The ASNC created a best practices document for nuclear cardiology laboratories during the novel coronavirus (COVID-19, SARS-CoV-2) pandemic. The suggestions in the guidelines can ally to any imaging modality, including computed tomography (CT), MRI and ultrasound. 

Skali elaborates on the following points in his discussion, which are specific recommendations in the ASNC and SNMMI COVID-19 guidance document:
   • Rescheduling non-urgent visits
   • Rescheduling elective surgeries and procedures
   • Using separate spaces for patients with known or suspected COVID-19 to prevent spread
   • Ensuring supplies are available
   • Promoting use of telehealth
   • Screen staff, patients and visitors before they enter the department
   • Minimize non-essential visitors into the department
   • Record symptoms at the start of the shift
   • Use personal protective equipment (PPE)for healthcare personnel
   • If available, use PPE for patients due to concern of asymptomatic transmission of COVID-19
   • Maintain strict hand hygiene
   • Maintain 6 feet distance in all patient/staff interactions when possible
   • Work remotely whenever feasible, especially with ready studies
   • Rotating staff schedules for on-site and off-site work
   • Use of rest only studies if possible
   • Use of half-time SPECT to speed exam times
   • Use of PET if available to speed exam times

FFR Technologies | March 26, 2020

James Udelson, M.D., chief of the division of cardiology, Tufts Medical Center, explains how cardiac computed tomography (CT) scans are being used to create image-derived fractional flow reserve (FFR) values to determine if a coronary lesion is flow limiting. The FFR-CT can help determine if the patient needs a stent, or if the disease can be treated with medication. Tufts uses FFR-CT evaluations on non-emergency chest pain patients to reduce the need for diagnostic catheterizations.

Coronavirus (COVID-19) | March 20, 2020

An interview with Ehtisham Mahmud, M.D., FSCAI, chief, Division of Cardiovascular Medicine, executive director of medicine, Cardiovascular Institute, director of  interventional cardiology and cardiac cath lab at UC San Diego Medical Center, and president of the Society for Cardiovascular Angiography and Interventions (SCAI). He explains the how cardiology departments in the U.S. are now postponing cardiovascular procedures due to novel coronavirus (COVID-19, SARS-CoV-2) containment efforts and new guidelines from Medicare calling for delay of all elective procedures in the country. 

Mahmud explains how patients are being prioritized, with acute myocardial infarction patients or others with acute, life-threatening conditions, or at high risk for a near term hospital admission, will still receive cardiac catheterizations, cardiovascular surgery or structural heart procedures for MitraClip and transcatheter aortic replacement (TAVR) under certain circumstances. All other procedures are being postponed until further notice based in the spread and infection rates of COVID-19. He said most hospitals, including his own, are moving to telehealth visits via phone or online to continue clinic work with patients, including those with chronic conditions such as heart failure.

The Centers for Medicare and Medicaid Services (CMS) announced March 18, 2020, that all elective surgeries, and non-essential medical, surgical and dental procedures should be delayed during the coronavirus outbreak. This move is three-fold. 
   1. It is to help with containment efforts by reducing patient and family travel to hospitals, which are at the center of the COVID-19 outbreak. 
   2. Delaying procedures will help preserve and inventory of personal protective equipment (PPE), hospital beds and ventilators and other medical supplies. 
   3. With the start of social distancing and the shut down of all large gatherings, this has severely impacted blood drives and other blood donations, so the nation's blood banks have severely limited supplies.

“The reality is clear and the stakes are high — we need to preserve personal protective equipment for those on the front lines of this fight,” said CMS Administrator Seema Verma.

This will not only preserve equipment but also free up the healthcare workforce to care for the patients who are most in need. Additionally, as states and the nation as a whole work toward limiting the spread of COVID-19, healthcare providers should encourage patients to remain home, unless there is an emergency, to protect others while also limiting their exposure to the virus.

Interview with Mike Stone, M.D., an emergency physician at Northwest Acute Care Specialists in Portland, Ore., director of point of care ultrasound education at Butterfly Network Inc., and and former chief of the division of emergency ultrasound at Brigham and Women's Hospital, Boston. He explains what clinicians look for in lung ultrasound to evaluate patients for plural wall thickening and areas of congestion inside the lung typical of pneumonia and seen in patients with novel coronavirus (COVID-19, also referred to clinically as SARS-COV-2). 

Small hand-held ultrasound systems may offer advantages over X-ray or computed tomography (CT), because the entire system can be contained inside a protective sheath, making it easier to disinfect the device rather than an entire imaging room. Point of care ultrasound (POCUS) systems also allow triage of patients in tents or other areas outside of the hospital where other imaging modalities are not available. 

Stone shares examples of COVID-19 ultrasound images from Butterfly Network POCUS system technology, which turns an iPhone into an FDA-cleared ultrasound device for multiple POCUS exam types. It is the first POCUS system reported to be used for triage and monitoring COVID-19 patients.

Magnetic Resonance Imaging (MRI) | January 06, 2020

Karen Ordovas, M.D., MAS, professor of radiology and cardiology at the University of California San Francisco (UCFS) School of Medicine and a Society of Cardiac Magnetic Resonance (SCMR) board member, explains how cardiac MRI can help in women's heart disease and to better define complex congenital heart anatomy. She spoke at the 2019 Radiological Society of North America (RSNA) meeting. 

She specializes in cardiac and pulmonary imaging, and has particular expertise in using CT and MRI techniques in cardiovascular imaging and the differences of presentation in imaging between male and female cardiac patients. Ordovas is helping advance education around heart disease in women and bring great awareness of quality tools to diagnose heart disease and how heart MRI can help. She also is heavily involved in the use of heart MRIs for pregnant women, since there is no radiation,  and patients with congenital heart disease where detailed imaging of the complex anatomy is required.

The use of cardiac MRI in congenital heart disease is common in serial imaging of patients with Tetralogy of Fallot (TOF), one of the most common congenital heart diseases for which patients are referred for post-operative magnetic resonance (MR) imaging evaluation. In the past few decades, surgery has proved successful, but most patients require repeat imaging throughout their lives and MRI can offer more detailed soft tissue imaging without the use of radiation.

Magnetic Resonance Imaging (MRI) | December 20, 2019

James Carr, M.D., chair of the Department of Radiology, Northwestern University, and incoming 2020 President of the Society of Cardiac Magnetic Resonance (SCMR), explains why MRI is an ideal cardiac imaging modality, at the 2019 Radiological Society of North America (RSNA) meeting.

Heart MRI offers advantages over computed tomography (CT) and echocardiography because of its excellent soft tissue delineation and its ability to offer information beyond anatomical imaging, such as perfusion, morphology and metabolism. MRI can be technically challenging and the exams requiring a long time, but recent advances have helped cur cardiac imaging times down significantly. Automation and artificial intelligence (AI) also is making post-processing and quantification mush faster, brining it closer to the time it takes to scan and post-process CT imaging.

Northwestern is was one of the early adopters of cardiovascular MRI. Carr said heart MRI was not common in regular clinical use until the past decade at some luminary centers. In 2005, Carr was given the opportunity to develop a clinical cardiac MRI program at Northwestern.
 
He said MRI scanners have improved, and now much faster than a decade ago. They are also more optimized for cardiac imaging. While heart MRI is well known in large hospital centers, Carr said it still needs to develop and expand to community hospitals and rural hospitals outside major population centers. 

Artificial intelligence is playing a significant role in cardiac MRI automation of speeding workflow and quantification. Carr said these technologies will become mainstream in the next few years. AI also will play an increasing role in risk prediction based on new image analysis algorithms in development.

Radiation Dose Management | December 19, 2019

 

Mahadevappa Mahesh, Ph.D., chief of medical physicist and professor of radiology and medical physics, Johns Hopkins University, Baltimore, treasurer of the American Association of Physicists in Medicine (AAPM),a board member of the American College of Radiology (ACR), presented a late-breaking study on how medical imaging radiation dose has started to drop over the past decade. He is the co-chair of the National Council on Radiation Protection and Measures Report (NCRP), and presented the most recent NCRP data analysis at the 2019 Radiological Society of North America (RSNA) meeting.

The new NCRP 184 report covers the period between 2006 and 2016, the period of the most current CMS data. It shows a decrease of about 20 percent in the radiation dose the U.S. population receives from medical imaging, compared to the NCRP 160 that covered the period of up to 2006.

Key findings of the study include:

   • CT dose dropped about 6 percent, despite a 20 percent increase CT scans since 2006;

   • Drop of more than 50 percent for nuclear imaging scans, mainly due to fewer procedures begin performed;

   • A 15-20 percent decrease across X-ray imaging modalities.

Mahesh says this shows the impact of using "as low as reasonably achievable" (ALARA) principals, new dose guidelines outlined jointly by numerous medical societies, and dose reduction initiatives like Image Wisely, Image Gently, and the American College of radiology (ACR) Dose Index Registry.

He said there was growing concern a decade ago when the last council report was published, which show a steep increase in radiation dose. This was mainly due to a rapid increase in the use of computed tomography (CT) and other types of X-ray based and nuclear radiotracer medical imaging. This prompted the ACR top create the Image Wisely program and push for the use of more thoughtful imaging doses based on patient size, using the "as low as reasonably achievable” (ALARA) principle. While CT dose was lowered, he said the biggest decline was in nuclear imaging.

Nuclear Imaging | November 07, 2019

Rob Beanlands, M.D., FASNC, 2019 American Society of Nuclear Cardiology (ASNC) president, shares a couple trends he sees in cardiac nuclear imaging. He is the Vered Chair and division head of cardiology and director of the National Cardiac PET Centre at the University of Ottawa Heart Institute, Canada.

He said overall trends he sees in nuclear cardiology include the use of better myocardial reserve quantification so it is clear whether revascularization would help patients. Beanlands also said there is increasing interest in positron emission tomography (PET) imaging because of its superior image quality and increasing access to PET radiotracers. New tracers on the horizon will also increase the image quality and flexibility of PET to accommodate exercise stress.

Hendel is a professor of medicine and radiology and the Sidney W. And Marilyn S. Lassen Chair in Cardiovascular Medicine, Tulane University. He also serves as the chief of the section of cardiology and director of the Tulane University Heart and Vascular Institute. 

He outlined three new radiotracers that may impact cardiac imaging:

   • Flurpiridaz F-18 PET perfusion agent that offers high quality images and can be used with exercise stress;

   • MIBG imaging to help better assess heart failure classes and if patients may need an ICD;

   • New F-18 agents to image cardiac amyloidosis; and

   • Nuclear agents to enable annexin imaging, allowing direct vsualization of myocardial apoptotic cells.

 

PET-CT | October 30, 2019

Rupa Sanghani, M.D., FASNC, associate professor, Rush Medical College, director of nuclear cardiology and stress laboratory, Rush University Medical Center, and associate director, Rush Heart Center for Women, explains how to create a high-volume cardiac positron emission tomography (PET) imaging program. She spoke on this topic at the 2019 meeting of the American Society Nuclear Cardiology (ASNC) and led a tour for attendees of the PET-CT system at Rush, which was located close to the conference. 

Sanghani said the advantages of PET myocardial perfusion imaging include faster exam times and allowing additional information from coronary reserve flow assessments to better understand if revascularization will help a patient's heart recover. The 16-slice CT scanner is used not only to attenuate the PET images, but to perform a CT calcium scoring exam to assess the patient's risk for future cardiovascular events. The Rubidium-82 radiotracer used for PET exams only has a 75 second half life, so it can help increase the number of exams a center is able to perform each day. At higher volume centers, PET is optimized to handle all the patients who require pharmacological stress exams. 

In the video, Sanghani  outlines what Rush did to design its room, covers basics on training, what to look for in a scanner and other considerations when creating a PET program.

Cardiac Diagnostics | October 29, 2019

Clyde Yancy, M.D., MSc, cardiology chief and vice dean for diversity and inclusion at Northwestern University, Feinberg School of Medicine, was a keynote speaker at the 2019 American Society of Nuclear Cardiology (ASNC) annual meeting. He said the traditional biases of seeing a patient and automatically making clinical assumptions because they are a certain race or gender are obsolete. For example, he said not all black patients have hypertension. Yancy added that genetics, especially with racial intermarriage over the past several generations, no longer predisposes patients to what is typically assumed for certain ethnic or racial backgrounds.

Yancy also said new research is showing how diet plays a major role in patient health and disease progression for things previously thought to be based on genetics. This includes the people who live in "food deserts" in urban areas where there are no sources of fresh food and vegetables, so they consume large amounts of packaged and processed foods that contain high levels of salt, phosphates and preservatives. He said these chemicals and diet may be the root cause of hypertension and diabetes in black populations in low income areas, rather than genetics as previously thought.

Advanced Visualization | August 09, 2019

An example of Siemens' photo-realistic Cinematic image reconstruction. This image is from a CTA exam from a Siemens Force CT scanner. 

Vendors who offer this realistic type of CT image rendering say it is not used for diagnostics. However, the technology can be helpful when explaining things to the patient and their family, educating physicians and staff, and for surgeons, since it offers a realistic view of the anatomy that is easier for most people to understand who are not familiar with cardiac anatomy as it appears in traditional CT multiplanar reconstruction (MPR) images. 

This example of software was demonstrated on the expo floor at the 2019 Society of Cardiovascular Computed Tomography (SCCT) meeting.

CT Angiography (CTA) | August 08, 2019

This is an example of an automated calcium scoring software to speed review of coronary artery calcium (CAC) scoring cardiac computed tomography (CT) scans. This advanced visualization software from Ziosoft uses artificial intelligence to segment the coronary vessels, identify valves and the aorta and then color code tag the calcium deposits and quantify the amount of calcified plaque in each vessel. It tallies the score into a table and computes an overall Agatston risk score. This risk score correlates to that patient's risk for a heart attack in the future. The software notes calcium in the heart outside the coronaries in valve leaflets and the aorta, but excludes this data. This type of automation is now offered by most advanced visualization and CT system vendors. This automation can save a large amount of post-processing time and make it easier for hospitals to offer low-cost CAC CT screening programs. 

CAC scans can be used to determine if a patient needs to go on statin therapy. An Agatston score of zero means the patient has no risk of coronary disease. 

Calcium in arteries is a marker for damage caused by vessel wall inflammation from atherosclerosis. Calcium can form from previously ruptured necrotic, lipid core plaques, also referred to as vulnerable plaques. These are the types of plaque responsible for heart attacks. When the core of these plaques rupture, the blood reacts to the exposed core similar to a wound and begins to clot, forming a thrombus in the vessel, which can block the blood flow. When the vessel heals over time it calcifies, leaving behind an easily identifiable marker on CT imaging. 

This example of software was demonstrated on the expo floor at the 2019 Society of Cardiovascular Computed Tomography (SCCT) meeting.

Computed Tomography (CT) | August 07, 2019

This is an example of in-stent restenosis shown using spectral CT imaging. This example was demonstrated by Philips Healthcare at the 2019 meeting of the Society Of Cardiovascular Computed Tomography (SCCT). It can sometimes be difficult to determine if showing inside a stent of CT is artifact or real. Spectral CT can definitely help make a diagnosis. This example shows Philips’ Effective Z visualization, where the image is created based on the atomic number of the elements present in the image. After removal of iodine from the image, it shows the shadow in the stent has the same atomic composition as the vessel intima.  

This example is from a Philips IQon dual-energy CT scanner. This system has spectral imaging always on without any need to change protocols. This allows the spectral to be used when needed for additional information without need to rescan a patient.
