A Multicenter, International, Prospective and Retrospective, Follow-up Registry to Monitor the Efficacy and Safety of the Occlutech Paravalvular Leak Device (PLD) in Patients With Mitral or Aortic Paravalvular Leaks

This is an international, multicenter, retrospective and prospective post-marketing follow-up registry designed to monitor the safety and efficacy of the Occlutech Paravalvular Leak Device (PLD) in patients with clinically significant mitral or aortic paravalvular leaks after previously implanted prosthetic heart valves who undergo transcatheter PVL closure in routine clinical practice. Up to 200 subjects are planned to be enrolled and followed after the procedure (Day 1-7, Day 30, 6-12 months, and annually up to 3 years) to evaluate device safety (including serious adverse device effects) and effectiveness, including reduction of paravalvular regurgitation assessed by echocardiography and clinical outcomes such as improvement in heart failure symptoms and/or reduced need for hemolysis-related transfusions.

European Multicentre Registry of Percutaneous Paravalvular Leak Closure

Paraprosthetic cardiac valve leaks are a progressive complication after after surgical or percutaneous heart valve replacement. These leaks can lead to heart failure and/or life-threatening hemolysis. Percutaneous closure of para-prosthetic leaks has been developed as an alternative to surgery in high-risk patients. These procedures remain technically challenging with a significant risk of failure and complications, but this risk is improved since the development of dedicated prostheses and the increased experience of the operators. The data in the literature concerning percutaneous leak closure remain limited and disparate and mostly retrospective.The impact of the procedures on the quality of life of patients is not known. Beyond the technical aspects and the follow-up of major cardiovascular events, investigators also wonder what is the impact of these procedures on the quality of life of patients. Investigators hypothesize that even a partial reduction in paraprosthetic leakage may be associated with an improvement in quality of life through reduction of transfusion needs and/or reduction of dyspnea. A prospective study is warranted to assess the technical and clinical and clinical results of these procedures, together with the evaluation of the the possible benefit on the quality of life of the patients.
