Ventricular Septal Defect with Aortic Regurgitation

摘要: Thirty-four patients with ventricular septal defect and aortic regurgitation, representing less than 5 per cent of our defect, are discussed. A loud, systolic murmur, characteristic is noted during infancy, whereas evidences regurgitation (protodiastolic murmur wide pulse pressure) does not usually appear until sometime between 2 10 years age. Clinical catheterization data indicate that the principal hemodynamic load result in a large pulmonary blood flow or high arterial pressure. In about 50 patients, significant pressure gradient across right outflow tract exists. Detailed pathologic studies defects anterior encroach to greater lesser degree on membranous bulbar septum. The coronary cusp one most severely involved, and,...
