Objective To investigate the efficacy and safety of hybrid perventricular device closure (PVDC) for the treatment of muscular ventricular septal defect (MVSD) in pediatric patients. Methods We retrospectively analyzed clinical data of 35 pediatric patients with MVSD who received hybrid PVDC in West China Hospital between 2009 and 2012. There were 16 males and 19 females with their median age of 3.9 years (range, 1 month to 7 years). There were 10 patients with single MVSD, 12 patients with multiple MVSD, 6 patients with other congenital heart defects, and 7 patients with post-surgical residual MVSD. Results Among the 35 patients, immediate complete closure was achieved in 28 (80.0%) patients. Residual shunt was noted in 7 (20.0%) patients. Median device size was 5 mm. Cardiopulmonary bypass was avoided in 19 patients. Two (5.7%) patients died postoperatively due to postoperative heart failure resulted from complex congenital heart defect. All survival patients were followed up for a mean duration of 6 months, and there was no late death. Thirty-one (93.9%) patients had good positioning of the closure devices but no residual shunt. Small residual shunt at the apex was noted in 2 (6.1%) patients. Conclusion Hybrid PVDC is an effective treatment for MVSD with relatively high successful rate but low mortality and morbidity, and its short-term results are satisfactory.
