Heart Valve Technology | February 18, 2020

Andrew Weintraub, M.D., FACC, associate director, of the Interventional Cardiology and Vascular Center, medical director of the Vascular and Structural Heart Center, Tufts Medical Center, discusses the use of temporary pacing in transcatheter aortic valve replacement (TAVR) patients. Implantation of TAVR valves can cause pressure from the valve against the septal wall of the heart, causing conduction delays. These delays do not necessarily mean the patient needs a permanent pacemaker.

Instead, Tufts Medical Center uses temporary pacing leads, a small catheter with two electrodes, placed in the right ventricle of the heart through a vein in the groin or neck. The lead is then connected to an external pacemaker allowing a physician to monitor and control a patient’s heart rate for up to several days.  The center uses the BioTrace Medical Tempo Lead, which incorporates a novel active fixation mechanism, bipolar electrodes and a soft tip. Stabilizers provide secure fixation and maintain stable pace capture. An elastomeric balloon may be inflated to aid passage of the lead through the venous vasculature and into the right ventricle, and  aids in wall apposition during deployment of the stabilizers. This design helps secure and stabilize the cardiac pacing lead with the goal of reducing complications and allowing patients to ambulate sooner after procedures.

Pacemakers | February 13, 2020

This video illustrates how the Micra AV leadless pacemaker is delivered via catheter and enables atrioventricular (AV) synchrony. The device was cleared by the U.S. Food and Drug Administration (FDA) in January 2020, expanding the number of potential candidates who can receive leadless, catheter delivered pacemakers in the U.S.

The device is the world’s smallest pacemaker with atrioventricular (AV) synchrony. It is indicated for the treatment of patients with AV block, a condition in which the electrical signals between the chambers of the heart (the atria and the ventricle) are impaired. It is similar to the single chamber Micra TPS pacemaker that has been on the market since 2016. However, the Micra AV has several additional internal atrial sensing algorithms which detect cardiac movement, allowing the device to adjust pacing in the ventricle to coordinate with the atrium, providing “AV synchronous” pacing therapy to patients with AV block. The device senses when blood is flowing through the right ventricle.

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.

Hemodynamic Support Devices | February 07, 2020

Interview with Navin Kapur, M.D., FAHA, FACC, FSCAI, executive director, The CardioVascular Center for Research and Innovation (CVCRI), director, Acute Mechanical Circulatory Support Program; director, interventional research laboratories; director of Cardiac Biology Research Center, Molecular Cardiology Research Institute (MCRI), Tufts Medical Center. He explains the Door-to-Unloading (DTU) Trial, which is using Impella hemodynamic support to unload the heart 30 minutes prior to percutaneous coronary intervention (PCI) in ST-elevated myocardial infarction (STEMI) patients. 

Data from a pilot trial and pre-clinical testing shows early hemodyanmic support prior to PCI helps reduce or eliminate the ischemia and limits myocardial damage due to ischemia. It also appears to help reduce the no-reflow phenomenon, reperfusion injury that  occurs in some heart attack patients who are revascularized, but the restoration of blood flow does not immediately help the patient. The DTU Trial is investigating if immediate hemodynamic support improves outcomes in STEMI patients. If it does, this could be a paradigm shift in therapy for these patients.

Wearables | January 09, 2020

The Consumer Electronic Show (CES) is the world's gathering place for consumer technologies, with more than 175,000 attendees and more than 4,400 exhibiting companies. New healthcare technologies are among the top trends at CES. This video offers a quick look at the trends specific to healthcare technology.

Artificial intelligence (AI) is one of the hottest technology trends across all product across the CES floor this year. There is also discussion by key note speakers that the internet-of-things (IOT) concept introduced at CES nearly a decade ago is now morphing into a new meaning for the interconnectivity-of-things. This can be seen in healthcare products shown here and across all types of consumer and business products. 

The device technology at CES include many examples of how integrated wearables can digitally enable healthcare. The future of healthcare will include system where consumers are continuously monitored with sensors, software and services that can pinpoint digital biomarkers — earlier warning signs that predict health events. This is the prediction of Leslie Saxon, M.D., executive director of the University of Southern California (USC) Center for Body Computing (CBC), is speaking as a panelist about digital health trends and challenges in the session “Proving the Impact of Transformative Technology.” 

Saxon is a board-certified cardiologist and digital health expert who understands how developing technologies can more accurately assess wellness and human performance among elite athletes, military personnel and patients. She explained this digital healthcare model of the future is a vast contrast to the current point-of-care model.

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.

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.

Pacemakers | February 13, 2020

This video illustrates how the Micra AV leadless pacemaker is delivered via catheter and enables atrioventricular (AV) synchrony. The device was cleared by the U.S. Food and Drug Administration (FDA) in January 2020, expanding the number of potential candidates who can receive leadless, catheter delivered pacemakers in the U.S.

The device is the world’s smallest pacemaker with atrioventricular (AV) synchrony. It is indicated for the treatment of patients with AV block, a condition in which the electrical signals between the chambers of the heart (the atria and the ventricle) are impaired. It is similar to the single chamber Micra TPS pacemaker that has been on the market since 2016. However, the Micra AV has several additional internal atrial sensing algorithms which detect cardiac movement, allowing the device to adjust pacing in the ventricle to coordinate with the atrium, providing “AV synchronous” pacing therapy to patients with AV block. The device senses when blood is flowing through the right ventricle.

Wearables | January 09, 2020

The Consumer Electronic Show (CES) is the world's gathering place for consumer technologies, with more than 175,000 attendees and more than 4,400 exhibiting companies. New healthcare technologies are among the top trends at CES. This video offers a quick look at the trends specific to healthcare technology.

Artificial intelligence (AI) is one of the hottest technology trends across all product across the CES floor this year. There is also discussion by key note speakers that the internet-of-things (IOT) concept introduced at CES nearly a decade ago is now morphing into a new meaning for the interconnectivity-of-things. This can be seen in healthcare products shown here and across all types of consumer and business products. 

The device technology at CES include many examples of how integrated wearables can digitally enable healthcare. The future of healthcare will include system where consumers are continuously monitored with sensors, software and services that can pinpoint digital biomarkers — earlier warning signs that predict health events. This is the prediction of Leslie Saxon, M.D., executive director of the University of Southern California (USC) Center for Body Computing (CBC), is speaking as a panelist about digital health trends and challenges in the session “Proving the Impact of Transformative Technology.” 

Saxon is a board-certified cardiologist and digital health expert who understands how developing technologies can more accurately assess wellness and human performance among elite athletes, military personnel and patients. She explained this digital healthcare model of the future is a vast contrast to the current point-of-care model.

Hemodynamic Support Devices | January 09, 2020

Richard Botto, CVT, RCSA, chief cardiovascular technologist, division of cardiology, cardiac cath lab, and Melissa Smith, RT, at Tufts Medical Center, Boston, explain the use of technology to remotely access data and waveforms on patients' temporary hemodynamic support system control consoles. 

Tufts Medical Center was one of the first hospitals to begin using the Abiomed Impella Connect technology, which enables remote smartphone access to Impella consoles. This allows a quick, remote check on patients using temporary hemodynamic support. The technology also is connected to a support center at Abiomed, so if a console or patient is experiencing issues out of the ordinary, techs can remote into the patient's Impella control console to take a look. Tuft's intensivists in the cardiac care unit (CCU) use the app to check on their patients' consoles without needing to walk into each room.

Cardiovascular Ultrasound | December 20, 2019

This is the LVivo auto cardiac ejection fraction (EF) app that uses artificial intelligence (AI) from the vendor Dia, displayed at the Radiological Society Of North America (RSNA) 2019. The user opens the app in a couple seconds the AI defines to myocardial border and calculates EF for left ventricle (LV). It is shown here integrated into the GE Healthcare VScan point-of-care-ultrasound system (POCUS).

The company also partners with Konica-Minolta to supply auto EF for ultrasound images on its cardio PACS.
