Ventricular septal defect and aortic regurgitation

摘要: We have reviewed our experience of 29 patients with the association ventricular septal defect and aortic regurgitation, 27 whom been treated surgically. Our present approach to surgical management is outlined embryology pathological anatomy are reviewed. The most common cause regurgitation was a prolapsed valve cusp, which occurred in 19 patients. Aneurysmal dilatation an sinus accounted for three patients, two had both abnormalities. In no found. Those cusp prolapse commonly large defects, nearly third were supracristal. Because into defect, sometimes right outflow tract, findings at cardiac catheterization often suggested erroneously that small infundibular obstruction present. Characteristic angiographic features demonstrated, particular deformed cusp. various techniques correction used described, majority having patch closure repair valve. Some residual usual, but it improved or minimized 18 23 survivors, more recent results particularly encouraging. Closure alone relieved heart failure 3-year-old child. There four operative deaths (15% mortality) severe before operation. medical course slowly increasing severity progression failure. However, individual unpredictable children developed within year onset their regurgitation. Infective endocarditis quarter usually followed development Despite difficulties felt prognosis, high risk once has supervened, hazard infective make early operation desirable.
