Plain-English summary
Ten dogs with a heart defect called a membranous ventricular septal defect (VSD) underwent surgery to fix the issue. The surgeries used two different approaches: one through the right atrium and the other through the right ventricular outflow. While both methods took about the same time, the dogs that had surgery through the right atrium recovered faster afterward. However, this approach did cause some moderate damage to the heart tissue. Overall, the right atrium incision was found to be the better option for repairing this type of heart defect in dogs.

Abstract
OBJECTIVE: To compare right atrium incision (RAI) and right ventricular outflow incisions (RVI) for surgical repair of membranous ventricular septal defect (VSD) facilitated by cardiopulmonary bypass (CPB). STUDY DESIGN: Retrospective study. ANIMALS: Dogs (n=10) with VSD. METHODS: Medical records of dogs that had VSD repair were reviewed. Membranous VSD without any malformation and abnormality was confirmed on several clinical examinations and by angiocardiography. RAI (5 dogs) and RVI (5 dogs) was used for VSD access and repair facilitated by CPB. Procedure comparison was by surgical duration, postoperative recovery period, and occurrence of postoperative arrhythmia. RESULTS: Duration of surgery was similar for RAI and RVI; however, postoperative recovery time was significantly reduced with RAI. Significant moderate operative damage occurred with right atrium incision. CONCLUSIONS: Right atrium incision was more effective than RVI for repair of membranous VSD using CPB. CLINICAL RELEVANCE: RAI should be considered in preference to RVI for repair of membranous VSD using CPB.
