Assessment of Paravalvular Leak After TAVI by Hemodynamic Measurements and Cardiac MRI

"Patients are studied on a clinical 1.5 Tesla scanner with cardiac radiofrequency receiver coil centered over the heart, and ECG monitoring. The following parameters are assessed:~Functional imaging: ECG-gated cine Steady-state free precession (SSFP) MRI images are obtained during repeated breath holds in long axis and short axis orientations covering the entire left ventricle. Global systolic and diastolic function are assessed, and left ventricular mass is calculated.~Flow imaging: ECG-gated 2D flow measurements are assessed above the prosthetic valve, and at the level of the pulmonary trunk."
