Radial Access | October 22, 2019

VIDEO: Trends in Radial Access for Percutaneous Coronary Interventions

Sunil Rao, M.D., chief of cardiology, Durham VA Health System and a professor at Duke University, and Prashant Kaul, M.D., director of the cath lab, Piedmont, Atlanta, discuss trends in radial access at the 2019 Transcatheter Cardiovascular Therapeutics (TCT) annual meeting. They discuss how radial access adoption has grown rapidly in the past few years and now makes up between 40-50 percent of percutaneous coronary interevention (PCI) procedural volume in the United States. They also discuss recent clinical trial data and the new concept of using distal radial access.

VIDEO: Use of Large Bore Vascular Closure

Ashish Pershad, M.D., chief of interventional cardiology, Banner University Medical Center, Phoenix, explains the trend of using closure devices to seal larger vascular access sites from the use of TAVR, EVAR, TMVR and hemodynamic support devices at the 2019 Transcatheter Cardiovascular Therapeutics (TCT) meeting. He was one of the moderators on a session on this topic at TCT 2019.

VIDEO: New PLATINUM Diversity Data Shows Early DAPT Cessation OK in Minorities With New Generation Stent

Roxana Mehran, M.D., FACC, FACP, FCCP, FESC, FAHA, FSCAI, professor of medicine and director of interventional cardiovascular research and clinical trials at the Zena and Michael A. Wiener Cardiovascular Institute at Mount Sinai School of Medicine, explains the use of short dual antiplatelet therapy (DAPT) in minorities from the PLATINUM Diversity Trial. The first trial data was released in 2017, and she presented new data from the study at the 2019 Transcatheter Cardiovascular Therapeutics (TCT) meeting.

The study looked at use of the Promus Element Plus Post-Approval Study and the clinical impact of dual-antiplatelet therapy (DAPT) cessation within 12 months of drug-eluting stent implantation in caucasians and minorities. It is one of the first large trials to stress the importance of diversity in clinical trials, which tent to reflect a population of older white men.

Hemodynamic Support Devices | October 16, 2019

VIDEO: Justification for Hemodynamic Support in Complex PCI

Jeffrey J. Popma, M.D., director of interventional cardiology clinical services at Beth Israel Deaconess Medical Center, professor of medicine at Harvard Medical School, explains the results of the PROTECT II and the new PROTECT III Study at the 2019 Transcatheter Cardiovascular Therapeutics (TCT) meeting. PROTECT III is the follow up to PROTECT II RCT and the largest-ever FDA study of hemodynamically supported, high-risk PCI patients.

He discusses the PROTECT II and PROTECT III studies, and real-life patient data from the Impella IQ Database.

CT Angiography (CTA) | August 08, 2019

VIDEO: Example of an Automated CT Cardiac Calcium Scoring Exam

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.

VIDEO: The History of CT Calcium Scoring

Arthur Agatston, M.D., clinical professor of medicine, Florida International University, Herbert Wertheim College of Medicine, is the name-sake of the Agatston score used in CT calcium scoring. He explains the history of the scoring system from the early 1990s and the evolution of CT technology for cardiac imaging. The latest American Heart Association (AHA) 2018 cholesterol guidelines now include the use of CT calcium scoring, which was a big topic at the Society of Cardiovascular Computed Tomography (SCCT) 2019 meeting.

VIDEO: Cardiovascular Damage Caused by Chagas Disease

Federico Asch, M.D., FASE, director of cardiac imaging research and director of the cardiovascular imaging lab, MedStar Health Research Institute, Washington, D.C., spoke about the cardiovascular impact of chagas disease and the symptoms that should be considered for patients who are from, or visited, South or Central America. He spoke on the topic at the 2019 American Society Of Echocardiography (ASE) meeting.

Chagas, also called trypanosomiasis, is a tropical parasitic disease caused by the protist Trypanosoma cruzi. It is spread through the bite of the triatominae insect, which is also known as the "kissing bug." Link to the Center for Disease Control (CDC) page on Chagas.

Asch served as the co-chair of the group that created the guidelines to image Chagas disease.

Read the guidelines at "Recommendations for Multimodality Cardiac Imaging in Patients with Chagas Disease: A Report from the American Society of Echocardiography in Collaboration With the InterAmerican Association of Echocardiography (ECOSIAC) and the Cardiovascular Imaging Department of the Brazilian Society of Cardiology (DIC-SBC).
