2 Clinical Trials for Various Conditions
The objectives of this study are to: a) evaluate and correlate the severity of paravalvular leak (PVL) assessed by both cardiac MRI and transthoracic echocardiography (TTE) after transcatheter aortic valve replacement (TAVR) with Medtronic Evolut-R or Evolut PRO bioprostheses; b) assess the inter and intraobserver variability of both imaging methods; and c) correlate the severity of PVL with post-TAVR changes in LV remodeling and clinical outcomes.
The study objective is to assess the agreement between cMRI PVL grading (based on regurgitant fraction) and TTE PVL grading (based on pressure half-time and the ratio of the jet arc to the circumference of the annulus).
