Aortic Stenosis Under Pressure: Decoding Low-Gradient Risk Profiles | JACC Baran

Author: American College of Cardiology April 29, 2025 Duration: 34:46

Hosts Mitsuaki Sawano, MD, co-host Shun Kohsaka, MD, and Nobuhiro Ikemura, MD, welcome Tomohiko Taniguchi, MD, from Kobe City Medical Center General Hospital, to discuss findings from the CURRENT AS Registry-2 on low-gradient severe aortic stenosis (AS). Based on data from over 3,300 patients across 21 Japanese centers, the study categorized AS into four hemodynamic subtypes, revealing that low-gradient AS with reduced LVEF had the poorest prognosis, paradoxical LFLG AS was associated with high rates of atrial fibrillation and advanced cardiac damage despite low valve calcification, and normal-flow LG AS frequently exceeded guideline-based calcification thresholds despite being labeled as moderate. Dr. Taniguchi emphasizes the need to revise conventional illustrations of AS subtypes by incorporating cardiac damage and frailty and underscores the importance of proper statistical interpretation in subgroup analyses.


Every week, the editors of one of the world's leading cardiology journals sit down for a conversation that goes beyond the printed page. JACC This Week, from the American College of Cardiology, brings together Editor-in-Chief Dr. Harlan Krumholz and Senior Consulting Editor Dr. Carolyn S.P. Lam. Their discussions provide essential context for the complex research published in the Journal of the American College of Cardiology, translating high-level science into meaningful insights. You’ll hear them dissect new studies, debate emerging trends, and explore the real-world implications of the latest findings in cardiovascular medicine. This isn't just a summary of the issues; it's a dialogue about how evidence is shaping modern heart care, from prevention to advanced intervention. The podcast serves as a direct line to the experts who are curating the science that defines global standards. Each episode feels like joining an informed, behind-the-scenes editorial meeting, where the nuances of patient care and clinical practice are thoughtfully examined. For anyone invested in cardiology-whether a practicing clinician, a researcher, or a dedicated student-this regular audio companion offers clarity and a deeper understanding of the forces driving the field forward. It’s where the published data meets practical conversation, all through the accessible format of a weekly podcast.
