From ACC.20/WCC: CCTA vs Invasive Angiography to Rule Out High-Risk CAD for Low/Intermediate Risk TAVR Patients

Dr. Kumar and Dr. Choi discuss their hypothesis-generating study, presented as a moderated poster at the American College of Cardiology 2020/World Congress of Cardiology conference, that evaluated pre-transcatheter aortic valve replacement (TAVR) planning coronary computed tomography angiography (CCTA). In low- to intermediate-risk TAVR patients, CCTA showed a high negative predictive value and effectively ruled out high-risk coronary artery disease, pointing toward a potential diagnostic pathway that may allow for reduced invasive angiography in these patients.
