VIDEO: Example of Strain Imaging That Can Derive Hemodynamic Pressure Loops

Advanced visualization company Medis recently purchased Advanced Medical Imaging Development S.r.l. (AMID), which developed software to automatically track and measure strain in echocardiograms. That technology is now being adapted for strain imaging in CT and MRI. Using this imaging data, the software also can noninvasively derive pressure gradient loops and curves, similar to using invasive pulmonary arterial (PA) hemodynamic pressure catheters. This information is useful in monitoring critically ill patients on hemodynamic support and to monitor worsening severity of heart failure.

The technology was discussed at the 2020 Society of Cardiovascular Computed Tomography (SCCT) virtual meeting. Examples of this technology are presented in this video.

VIDEO: What to Expect at the Virtual TCT 2020 Meeting

With COVID-19 forcing all medical conferences to go virtual in 2020, Juan F. Granada, M.D., CEO of the Cardiovascular Research Foundation (CRF) explains how this year's Transcatheter Cardiovascular Therapeutics (TCT) 2020 meeting is being structured and some of the advantages of the virtual format. He also shares how the virtual format was actually very helpful at CRF's Transcatheter Valve Therapeutics (TVT) Structural Heart Summit earlier this summer.

Virtual cardiology meetings so far in 2020 have found the format enables much more participation by international physicians than in the past. TCT is using this idea to focus sessions aimed at Asia and Europe at different parts that correspond to the end of the work day in those parts of the world. Granada said U.S. focused sessions will take place toward the end of the day across the United States to accommodate more attendees during the sessions, since many will be attending after they are finished for the day, rather than take days off to attend.

Left Atrial Appendage (LAA) Occluders | July 24, 2020

VIDEO: Overview of LAA Occlusion Using the Watchman FLX

Devi G. Nair, M.D., FHRS, director of cardiac electrophysiology, St. Bernards Heart and Vascular Center, Jonesboro, Ark., was an investigator in the PINNACLE FLX clinical trial for the Boston Scientific Watchman FLX left atrial appendage (LAA) occluder device.

The newest iteration of the Watchman was cleared by the U.S. Food and Drug Administration (FDA) in July 2020. Read more about the Watchman FLX

The transcatheter implant is used in close the LAA, a pouch that forms part of the left atrium. The LAA is implicated in the formation of blood clots that cause stroke in patients with atrial fibrillation (AF). The Watchman FLX is indicated to reduce the risk of stroke in patients with non-valvular AF (NVAF) who need an alternative to oral anticoagulation therapy by permanently closing off the left atrial appendage.

Nair is currently involved with another trial of the Watchman FLX, OPTION FLX trial, which is examining the use of LAA occlusion in post-ablation patients.

Nair is also chairman for the Heart Rhythm Society (HRS) member engagement sub-committee and is a board member of the Arkansas chapter of the American College of Cardiology (ACC).

Cardiogenic Shock | July 15, 2020

VIDEO: New Research in Cardiogenic Shock at Tufts Medical Center

Navin Kapur, M.D., FAHA, FACC, FSCAI, director, Acute Mechanical Circulatory Support Program and executive director of The Cardiovascular Center for Research and Innovation (CVCRI), Tufts Medical Center, explains the research being done by the Cardiogenic Shock Working Group, which is headed by Tufts.

The Cardiogenic Shock Working Group (CSWG) has created a patient registry now includes 15-20 centers in the United States and data on more than 2,000 patients who suffered shock either from heart failure or acute myocardial infarction (MI). It also includes hemodynamic data on more than 1,100 patients. It also includes all types of mechanical circulatory support devices, from intra-aortic balloon pump (IABP), incrementally higher levels with a percutaneous Impella pump, TandemHeart, and extracorporeal membrane oxygenation (ECMO).

Research last year showed three types of phenotype profiles in cardiogenic shock patients, including non-congested, cardio-renal and cardio-renal-hepatic. Kapur also said there is evidence that there is venous involvement that needs to be considered in future research.

The large amount of variables in the patient data from the CSWG is partly examined by artificial intelligence (AI), which helped identify the three shock phenotype profiles.

VIDEO: Impact of COVID-19 on Electrophysiology Programs

Devi G. Nair, M.D., FHRS, director of cardiac electrophysiology, St. Bernards Heart and Vascular Center, Jonesboro, Ark., explains the impact of COVID-19 (SARS-CoV-2) on her EP program and what was done to continue operations and recover procedural volume. She also shares how EP played a role in the team approach to treating coronavirus patients at her center.

Her experience is an example of how centers have dealt with issues related to the pandemic, including shutting down elective procedures, treating emergent cases, reopening services, new safety precautions and how telehealth played a role.

Nair is also chairman for the Heart Rhythm Society (HRS) member engagement sub-committee and is a board member of the Arkansas chapter of the American College of Cardiology (ACC).

Coronavirus (COVID-19) | May 29, 2020

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

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 28, 2020

VIDEO: Why QT-prolongation Occurs in COVID-19 Patients on Hydroxychloroquine and Azithromycin

Interview with Andrew D. Krahn, M.D.,FHRS, head of the division of cardiology at St. Paul’s Hospital, and professor of medicine at the University of British Columbia, and vice president of the Heart Rhythm Society (HRS). He is an expert in long QT syndrome (LQTS) and is involved with the National Long QT Registry. He explains the issues with the drugs being used to treat coronavirus (COVID-19, SARS-CoV-2) patients and why these combined with the cardiac impact of the virus is causing prolonged ECG QT segment prolongation, leading to deadly arrhythmias. COVID-19 can cause myocarditis that causes QT prolongation and the front-line COVID drugs hydroxychloroquine and azithromycin also cause QT prolongation.

The U.S. Food and Drug Administration (FDA) issued a Drug Safety Communication April 23, 2020, reminding doctors there are serious side effects when using hydroxychloroquine and chloroquine in the off-label use to treat COVID-19 patients. This includes potentially life-threatening heart rhythm problems. The FDA said case reports from the FDA Adverse Event Reporting System database, published medical literature and the American Association of Poison Control Centers National Poison Data System are reporting serious heart-related adverse events and patient deaths. Read more about this alert.

The FDA warning confirmed fears from the American Heart Association (AHA), the American College of Cardiology (ACC) and the Heart Rhythm Society (HRS). These societies April 8 jointly published a new guidance, “Considerations for Drug Interactions on QTc in Exploratory COVID-19 (Coronavirus Disease 19) Treatment,” to detail critical cardiovascular considerations in the use of hydroxychloroquine and azithromycin for the treatment of COVID-19. The societies warned that use of these agents in a large number of patients in combination would results in arrhythmias and deaths. Read more.

However, there are numerous advocates that argue hydroxychloroquine needs to be used in less sick patients who are not already hypoxic to treat COVID, but it is being used primarily in very sick patients where it is not effective. Advocates also argue the drug can be used to help prevent coronavirus, similar to the drug's effect in preventing malaria. In terms of drug safety, advocates argue the drug has been used in millions of patients for more than 50 years without a high risk of arrhythmias. Several trials are now underway in the United States to test its use against COVID-19, but enrollment has been hampered because of the FDA warning. There will likely be more interest in hydroxychloroquine after it was revealed May 18, 2020, that President Trump is taking the drug for prophylaxis against COVID-19.
