Clinically significant paravalvular leak (PVL) may complicate both surgical and transcatheter valve implantation. Percutaneous PVL closure (PPVLC) is becoming an increasingly attractive alternative to redo surgery, with demonstrated lower mortality morbidity rates. Echocardiographic techniques are crucial for accurate diagnosis, defect sizing, determining the appropriate size of sealing devices. There no consensus on optimal imaging modality PVLs. We aimed compare transthoracic...
