RESUMO
Objective: To review the surgical outcome of doubly committed subarterial [DCSA] ventricular septal defect repair
Method: Data of 51 patients of doubly committed sub arterial Ventricular septal defect from January 2012 to June 2017 that were referred to Chaudhary Pervaiz Elahi institute of Cardiology Multan was retrospectively reviewed using electronic database. All patients were operated by first author. In our study, we segregated patients into four main groups depending on presence or absence of aortic structural defect and degree of aortic valve regurgitation. Group-A comprised of nineteen [37%] patients who neither had aortic structural nor functional abnormality while GroupB had six [11.7%] patients, having aortic valve cusp prolapse without aortic regurgitation. Group-C and Group-D consists of seventeen [33.3%] and nine [17.6%] patients respectively depending upon degree of aortic regurgitation. Furthermore, six [11.7%] patients among these 51 had associated defects as well
Results: Group-A patients had no aortic valve regurgitation post operatively and at follow up of 22.6 months [1.8 years] as well. In Group-B, aortic valve was not addressed and aortic regurgitation was also not present post operatively or on follow up of 33.6 months [2.8 years]. Similarly, in Group-C aortic valve was not addressed, these patients also did not show progression of disease on regular follow up of 18 months [1.5 year]. While, in Group-D, eight patients underwent aortic valve repair and one patient had aortic valve replacement. Aortic regurgitation improved significantly in all patients of this group and remained, unchanged on follow up of 22.7 months [1.8 years]
Conclusion: Early closure of doubly committed subarterial ventricular septal defect with appropriati aortic valve disease caa halt the process of disease progression
