Percutaneous closure of congenital and acquired ventricular septal defects--considerations on selection of the occlusion device 总被引:9,自引:0,他引:9
Michel-Behnke I Le TP Waldecker B Akintuerk H Valeske K Schranz D 《Journal of interventional cardiology》2005,18(2):89-99
Nonsurgical closure of congenital and acquired ventricular septal defects (VSD) has become increasingly acceptable with the availability of various occlusion systems that allow percutaneous treatment of muscular and membranous defects. This study describes a series of 12 patients (0.2-74-years-old) who underwent defect closure with six different occlusion systems. Device selection according to anatomy and outcome is highlighted. Seven VSDs were located in the membranous part of the septum, five in the mid-muscular septum. Complex heart lesions were present in five postmyocardial infarction VSD in one and residual postsurgical defects in three patients. The size of the VSD ranged from 2.6 to 10 mm. The applied devices were: Amplatzer muscular VSD occluder (n=4), Amplatzer septal occluder (n=2), Amplatzer duct occluder (n=1), Amplatzer membranous VSD occluder (n=2), Nit-Occlud coil (n=2), and Cook PDA coil (n=1). The devices were implanted successfully in nine patients. There was complete VSD closure in eight patients within the first 24 hours. In one patient, a trivial residual shunt disappeared at 6 months follow-up. Because of device instability, two occluders were removed during catheterization. In two other cases, tricuspid valve tissue was entrapped in the occluder and had to be removed surgically, one of them during the consecutive Rastelli operation. Neither significant arrhythmia, nor thromboembolism or hemolysis occurred in out patients during follow-up. Transcatheter closure of VSD is an attractive alternative to surgery. In complex congenital heart disease, surgical-interventional hybrid therapy may improve morbidity and total outcome. The recently developed Amplatzer VSD devices allow closure of muscular and membranous VSDs. Implantation and short-term follow-up are superior to the formerly used devices. Long-term effects have to be evaluated in further studies. 相似文献

OBJECTIVES: Most perimembranous ventricular septal defects (pmVSD) that are still patent in adult life are small, hemodynamically and clinically unimportant, and do not require any intervention. However, surgery in adulthood for those that need to be closed carries significant morbidity. A trans-catheter technique for closing pmVSDs has been developed, and this paper describes our initial experience using the Amplatzer membranous septal occluder (AMSO). PATIENTS/METHODS: Twelve patients, 9 female and 3 male, median age 34.5 years (range: 21-67) underwent catheterization for attempted pmVSD closure. Ten of the defects were native and 2 were post-operative residual defects. Transcatheter VSD closure was performed as previously described, under general anesthesia and with trans-esophageal echocardiographic (TEE) monitoring. Patients had a moderate to large left to right shunt (mean Qp/Qs = 2.0+/-0.4) with mild left heart volume overload and near normal pulmonary pressure. All 10 native pmVSDs were closed successfully, 9 with AMSO and one with an Amplatzer muscular VSD occluder, after failure to implant the AMSO. There was one post procedural complication--self-limiting retroperitoneal bleeding. Three patients had a residual leak. Attempted VSD closure in the 2 patients with post surgery residual shunt was unsuccessful. CONCLUSION: We conclude that transcatheter mVSD closure with the AMSO is an efficient and safe alternative to surgery in carefully selected adult patients with native pmVSDs. 相似文献

BACKGROUND: The interest in transcatheter ventricular septal defect (VSD) closure is continuously growing. Therefore, we report our experience in perimembranous (Pm) and postinfarction (Pi) VSD closure. METHODS: All patients, older than 16 years, were selected from a data base, in which Pm and Pi VSDs were registered.The patients' files were reviewed until the most recent follow-up date. RESULTS: Nine (7 male, 37.4 +/- 12.8 y) and 8 (6 male, 76.3 +/- 6.2 y) patients underwent a Pm (group A) and Pi VSD (group B) closure, respectively. One female patient was treated for a posttraumatic VSD (26 y). In group A, 7 patients were closed with the Amplatzer perimembranous VSD occluder, one with the muscular VSD occluder, and one patient with the atrial septal defect occluder. All patients in group B were treated with the muscular VSD occluder. In the post-traumatic VSD an Amplatzer patent foramen ovale occluder was used. Device implantation was feasible in all, except in two patients with extremely large VSDs (one Pm and one PiVSD). Total transcatheter closure or small residual leakage was achieved in 7/8 patients in group A, but one patient needed surgical VSD repair because of massive haemolysis, another patient died 9 months later. A small or moderate shunt was present immediately after the procedure in all patients of group B. No device-related complications were reported, but all, except one patient, died within 2 weeks after the procedure because of an extremely high co-morbidity (logistic Euroscore 70 +/- 25%).Total closure was achieved in the post-traumatic VSD. CONCLUSION: Transcatheter closure of Pm and Pi VSD with Amplatzer septal occluders in adults is feasible and safe, but the post-procedural prognosis totally depends on the aetiology of the VSD and its co-morbidity. 相似文献

Transcatheter closure of atrial septal defects has been employed increasingly in the past decade. This technique is now regarded as the treatment of choice for patients with appropriate atrial septal defects. Transcatheter closure of ventricular septal defects (VSDs) has undergone fewer clinical trials, even though VSDs are more common than atrial septal defects. The implanted device does not seem to embolize and complications are few. Decreases in left ventricular and diastolic pressure and improvement of ventricular function have been reported early following device closure, and the left-to-right shunt has been either eliminated or dramatically reduced. In small infants who are in heart failure at a young age and who weigh less than 8 kg, which is below the recommended threshold for device closure, technological advancements in device size and catheter manipulation are needed before VSDs can be closed. A large number of VSDs, particularly if small to medium in size, will become smaller or close spontaneously, making intervention unnecessary. Muscular VSDs have been closed with transcatheter devices for the past 15 years. Although perimembranous defects are more common than muscular defects, they have not become more amenable to closure since the introduction of the Amplatzer VSD occluder device (AGA Medical Corporation, Golden Valley, MN). Previous devices, such as the Rashkind and button devices, have been unsuccessful in attempts at closure of the VSDs because of the proximity of the defects to the aortic valve and potential aortic valve damage. Before the transition is made to routine therapy, large, multicenter trials are justified to test the feasibility, safety and efficacy of nonsurgical closure of VSDs. In this review, I discuss the current applications of transcatheter closure of membranous, perimembranous and muscular VSDs, in particular with Amplatzer devices, and the implications for future development. 相似文献
