Invasive Assessment of Right Ventricular to Pulmonary Artery Coupling Improves 1-year Mortality Prediction After Transcatheter Aortic Valve Replacement and Anticipates the Persistence of Extra-Aortic Valve Cardiac Damage.

Invasive Assessment of sPAP Levels Refines the Predictive Value of TAPSE/sPAP Ratio to Foresee 1-Year All-Cause Mortality After TAVR Assessment of sPAP levels by echocardiography and right heart catheterization showed only moderate, yet highly significant correlation (Pearson correlation coefficient R : 0.53, p value: <0.0001) ( Figure 2 a).
