    Abstract:
    BACKGROUND: Outcome data of doubly committed subarterial ventricular septal defect closure in adults are limited. METHODS: A review was made of the inpatients >18 years of age who underwent doubly committed subarterial ventricular septal defect closure between June 2010 and June 2017. RESULTS: The patients were categorised into two groups: The valve intervention group consisted of 31 patients who underwent aortic valvuloplasty, aortic valve replacement, or repair of sinus Valsalva aneurysm in addition to doubly committed subarterial ventricular septal defect closure; non-valvular intervention group comprised 58 patients who underwent only doubly committed subarterial ventricular septal defect closure. The groups did not differ by sex and age. Patients in the valve intervention group, with a larger ventricular septal defect size, were shorter and tended to be lighter. The valve intervention group had more patients with pneumonia perioperatively. No infective endocarditis and reoperation were noted during the study period. At last follow-up, 91 and 96.6% of the studied patients were free from left ventricle dilation and pulmonary hypertension. In patients without pre-operative aortic regurgitation, 12 developed new mild aortic regurgitation during the follow-up. CONCLUSIONS: About 34.8% of adult patients with doubly committed subarterial ventricular septal defect required concurrent intervention on aortic valve or sinus Valsalva aneurysm. The midterm results of doubly committed subarterial ventricular septal defect closure in adult patients were favourable. However, the incidence of new mild aortic regurgitation after ventricular septal defect closure was high (27.3%). Long-term follow-up of aortic regurgitation progression is needed.
