Minimally Invasive Transradial Percutaneous Closure of Aortic Paravalvular Leaks: Following the Steps of Percutaneous Coronary Intervention

Two patients with severe aortic paravalvular leaks (PVLs) in a mechanical prosthesis were percutaneously treated. Procedures were performed with mild sedation, angiographic guidance, and a 6-French right radial artery approach with good final results. Percutaneous PVL treatment is routinely performed with general anaesthesia, transesophageal echocardiographic guidance, and femoral access. Although another case of radial aortic PVL closure has been previously reported, it was performed with an 8-French radial sheath, transesophageal echocardiographic guidance, and general anaesthesia. According to our initial experience, aortic PVLs could be treated in a minimally invasive way. Larger studies should be conducted to confirm these observations.
