AIMS: The purpose of this study was to evaluate the feasibility and short-term efficacy of transcatheter @entity2478 closure using different occlusion devices. METHODS AND RESULTS: Twenty-one @entity1 underwent transcatheter closure of either aortic or mitral @entity2478 from June 2002 to February 2006 using the Amplatzer PDA, @entity2438 or @entity1757 occluder. All @entity1 had symptoms and signs of haemolysis and/or @entity299 with dyspnoea.Implantation of a device was technically successful in twenty @entity1 (95%). Immediate residual leak was found in seventeen @entity1 (85%). Significant shunting persisted in nine cases during follow up (45%). @entity2319 was observed in one @entity1 . Severe complications during follow up led to early @entity204 in one @entity1 and surgical intervention in three. A successful second catheter treatment was performed in another three @entity1 . The event-free survival from re-operation, @entity204 and @entity64 at the end of the observation period was 80%. CONCLUSION: Transcatheter closure of @entity2478 is a technically feasible, but demanding procedure. Residual leaks are common and may worsen pre-existing haemolysis. Due to the significant ongoing morbidity in this group of @entity1 and the complexity of follow up individual @entity1 results differ considerably. Nevertheless, it is possible to achieve some symptomatic relief, thus an interventional approach should be discussed as a potential treatment option for those @entity1 with a limited defect and who are not deemed suitable for another operation.
