Plain-English summary
Two dogs were diagnosed with a heart problem called a partial atrioventricular septal defect, which affects blood flow in the heart. They underwent surgery to repair the defect, which involved making an incision in the chest and using special techniques to fix the heart's valves. Both dogs survived the surgery and were doing well for over a year afterward, but one dog developed a heart issue called mitral regurgitation, where blood leaks back into the heart. Overall, the surgery was successful, but the long-term health of the dogs may depend on how well the heart valves function after the repair.

Abstract
Partial atrioventricular (AV) septal defects consist of an ostium primum defect and malformation of the septal cusp of the mitral valve. A partial AV septal defect was diagnosed by means of echo-cardiography in 2 dogs. Transatrial septal blood flow was high enough in both dogs to warrant surgical correction. Defects were repaired through right fifth intercostal thoracotomies, with the aid of cardiopulmonary bypass. An incision was made in the right atrium to expose the AV septal defect, and the mitral valve was inspected through the septal defect. The cleft in the septal cusp of the mitral valve was repaired with mattress sutures of 6-0 polypropylene. The septal defect was closed with autogenous pericardium harvested from the right aspect of the pericardial sac. Both dogs survived surgery and were alive 15 and 42 months, respectively, after surgery, however, 1 dog developed progressive mitral regurgitation after surgery. Partial AV septal defects can be successfully repaired in dogs. Long-term prognosis probably depends on the adequacy of the mitral valve repair.
