Discover the complexities of assessing right ventricular function in tricuspid regurgitation with Dr Alison Duncan

This presentation, part of a comprehensive series on complex cases in interventional cardiology, explores the challenges and evolving approaches to RV function assessment when traditional imaging parameters fall short.

Dr Duncan addresses the fundamental limitations of conventional echo measurements in severe TR, including why TAPSE inadequately reflects true contractility and why pulmonary arterial pressure cannot be reliably measured with free TR due to laminar flow patterns. The discussion reveals the critical importance of concordant versus discordant invasive and echocardiographic pulmonary pressure measurements, demonstrating that discordant readings signal worse patient outcomes and underscore why "all bets are off" for PA-RV coupling assessment in free TR.

Drawing from contemporary evidence and clinical practice at specialized heart valve centers, the presentation emphasizes the value of right heart catheterization for comprehensive hemodynamic assessment, including pre- versus post-capillary pulmonary hypertension classification and stroke work analysis.
