Abstract

Surgical closure of multiple muscular ventricular septal defects (MVSDs) is associated with mortality and morbidity; therefore, both surgeons and cardiologists welcome a nonsurgical safe approach. We report our initial results of catheter closure of MVSD using the new Amplatzer muscular VSD occluder delivered via the venous or arterial routes. Eight patients with MVSD underwent closure of their VSDs using the Amplatzer VSD occluder under generalendotracheal anesthesia. The mean +/- SD of age was 5.4 +/- 3.1 years (2-10 years) and mean weight was 18.4 +/- 6.5 kg (11.5-29 kg). All patients hadleft ventricular volume overload with mean Qp/Qs ratio of 1.7 +/- 0.6 (1.4-3). The location of the VSD was mid muscular in four, anterior in two, apical in one, and posterior in one. The systolic pulmonary artery pressure ranged from 25 to 85 mm Hg (mean, 39.9 +/- 18.8 mm Hg). The device was implanted successfully in all eight patients. In five patients (four mid muscularand one apical), the deployment of the device was anterograde from the right internal jugular vein and in three patients (two anterior and one posterior VSD), the initial attempt at anterograde deployment was unsuccessful due to kinking in the delivery sheath; therefore, retrograde deployment was attempted successfully. The size of the device used ranged from 6 to 14 mm (the size of the connecting waist). In patients with elevated pulmonary artery pressure, repeat measurements immediately after closure revealed normalization in all. There was immediate complete closure of the defect in two patients and six patients had trivial residual shunt (foaming through the device), which disappeared completely within 24 hr in five and at 6-month follow-up in the sixth patient. The mean fluoroscopy time was 37.1 +/- 13 min (11.7-55 min). Complications encountered included transient junctional rhythm in one patient. No blood transfusion was required. On follow-up evaluation, there has been no episode of endocarditis, thromboembolism, hemolysis, or wire disruption, we conclude that the Amplatzer MVSD occluder is a safe and effective device for closure of MVSDs up to 12 mm in diameter. Further clinical trials with this device are underway. (C) 2000 Wiley-Liss, Inc.
