title: Comparison of right atrium incision and right ventricular outflow incision for surgical repair of membranous ventricular septal defect using cardiopulmonary bypass 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).
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  RAI should be considered in preference to RVI for repair of membranous VSD using CPB.
