SYSTOLIC IMPEDANCE AND DIASTOLIC WALL STRESS ARE NOVEL PREDICTORS OF HEART FAILURE HOSPITALIZATIONS IN PATIENTS UNDERGOING TRANSCATHETER AORTIC VALVE REPLACEMENT

Unlike native aortic valves with normal transvalvular gradients, stenotic aortic valves have altered flow dynamics both during systole and diastole. Such hemodynamic changes can predict heart failure (HF) hospitalizations after Transcatheter Aortic Valve Replacement (TAVR). Prognostic tools for the
