Abstract
Paravalvular regurgitation/leak (PVL) frequently occurs following prosthetic cardiac valve implantation. The incidence of PVL following mitral valve replacements (MVRs) is 5% to 17% and is about 5% to 10% after aortic valve replacements (AVRs). Symptoms of PVL are either due to heart failure or haemolysis. Surgery for PVL is associated with significant morbidity and mortality. Percutaneous closure of PVLs has emerged as an attractive alternative to surgery. An aortic PVL is closed using less complicated techniques via the retrograde transfemoral approach. Transcatheter closure of mitral PVLs is technically challenging and requires more complex catheter techniques than aortic PVLs. Transoesophageal echocardiogram (TEE) guidance in mitral leaks is mandatory during all stages of the procedure.
