Postinfarction ventricular septal defect closure with Amplatzer occluders.

OBJECTIVE: Postinfarction ventricular septal defect (PIVSD) is a rare and life-threatening complication with high risk of both surgical and medical treatment. Another option available now is transcatheter closure. The purpose of this paper is to report the results of such treatment with Amplatzer occluders. METHOD: Seven patients aged from 51 to 71 years were included. The procedure was performed between 2 and 10 weeks after myocardial infarction. One patient had double residual VSD (2 months after previous surgery) and another, coexisting critical stenosis of right coronary artery (RCA). All patients were in III/IV NYHA class, on intropes, one patient on aortic balloon counterpulsation. Venous jugular approach was used to close the VSD in six patients, venous transfemoral in one patient. Implantation of six Ampaltzer atrial septal occluders (ASO) and one muscular Amplatzer VSD occluder (VSO) were performed. RESULTS: All procedures but two were finished successfully. In one patient, the defect could not be entered neither from the venous nor the arterial side due to unusual oblique course (which was confirmed during subsequent operation). In the second patient (2 weeks after MI), the reason was unstable position of 24 mm ASO (probably due to necrotic borders of VSD). Immediate significant clinical improvement was achieved in all patients, in whom PIVSD was closed with Amplatzer occluders. In one postsurgical patient, two ASO were used; in another patient, prior to VSD closure, PTCA and stent implantation to RCA was performed. The stretched diameter of PIVSD ranged from 8 to 22 mm, the size of implanted Amplatzer occluders from 12 to 24 mm. Fluoroscopy time was 60 min (18-120). During the procedure, ventricular fibrillation requiring defibrillation was observed in three patients. One patient died 1 week after the procedure because of multiorgan failure and increasing mitral incompetence (MI). CONCLUSIONS: Despite some technical problems, implantation of Amplatzer occluders, is an attractive option of treatment of patients with subacute PIVSD.

Abstract：

Objective To assess the application of echocardiography in mini-invasive surgical device closure of ventricular septal defect (VSD). Methods 73 VSD patients including 35 with aneurysm formation and among them 21 with multi-defects in the aneurysm were treated by mini-invasive device closure. A closure device was positioned to the defect through parastemal mini-incision in all patients. TEE was used to monitor the whole procedure, to guide the device positioning and to evaluate the curative effect instantly after operation. All patients were evaluated by TTE one year postoperatively. Results All patients were successfully positioned closure devices by TEE guiding. 9 cases were found with trace to small amount residual shunt instantly after operation. 7 cases still had small amount residual shunt at the time of 48 hours after the operation. In the one year follow-up, 4 cases had residual shunt, but the size and volume of left ventricle were significantly reduced than those before operation, and the pulmonary artery systolic pressure was also reduced. Conclusion Echocardiography possesses an important role in preoperative indication screening, intraoperation monitoring and evaluating the curative effect postoperatively.
