Doubly committed subarterial ventricular septal defects: echocardiographic features and surgical implications.

摘要: Doubly committed subarterial (supracristal, subpulmonary) ventricular septal defects are often complicated by aortic regurgitation resulting from valve herniation into the defect. The clinical, echocardiographic and catheterization findings in 48 patients aged 0.3 to 46.4 years (median 9.5) with a doubly defect were reviewed. Aortic was present 38 (79%) 55% of these had regurgitation. prevalence both increased gradually advancing age. closed surgically 41 patients.
