TCT-874 Hemodynamic Assessment of Residual Paravalvular Aortic Regurgitation (PAR) after TAVI: Impact of Myocardial Supply-Demand Ratio (DPTI:SPTI) on Survival

Significant PAR has been shown to occur in 20% of pts. undergoing TAVI and associatd with increased cardiovascular mortality. Pathophysiologially, this may be explained by a reduced DPTI:SPTI, which is found in severe aortic stenosis. We sought to evaluate the already established cut-off value of 0.
