ABSTRACT
Paravalvular leak (PVL) is a relatively rare, but serious complication occurring in up to 10% of patients after prosthetic aortic valve replacement and in up to 17% of patients after prosthetic mitral valve replacement. Up to 5% of patients will present with symptoms of congestive heart failure or mechanical haemolytic anaemia due to PVL and need further surgical or interventional treatment. Surgical repair is often technically challenging and carries a high mortality and morbidity risk. Catheter-based closure of PVL has emerged as an alternative approach especially for patients with relevant comorbidities at high surgical risk. Interventional closure of PVL is a complex procedure, which needs to be performed by an experienced team of interventional cardiologist, echocardiographer and anesthesiologist. To date available clinical results are promising showing low complication rates and high technical or clinical success rates of catheter-based closure of PVL (60-90%). Compared to surgical closure of PVL lower mortality rates (30-days mortality rate 4,6%) have been documented in patients treated by catheter-based closure of PVL in clinical practice. Therefore interventional closure seems to be a promising option, which need to be discussed with every symptomatic patient suffering from PVL prior to therapeutical decision making. To date only sparse clinical data is available regarding indication and clinical outcome of patients undergoing catheter-based PVL in clinical practice. Therefore interventional closure of PVL should be limited to experienced interventional cardiologist at present. All patients treated should further be enrolled into a clinical registry to evaluate the safety and efficacy of catheter-based closure of PVL in clinical practice.
