Reversing Regurgitant Physiology: Pressure-Volume Insights After Dedicated TAVR for Pure Aortic Regurgitation.
BACKGROUND Dedicated transcatheter aortic valve replacement (TAVR) devices for the treatment of pure aortic regurgitation (AR) have emerged as an alternative to surgery for patients at high or prohibitive operative risk. However, the immediate hemodynamic effects of TAVR in this setting remain poorly characterized. C...
