Ruptured aneurysm of the sinus of Valsalva and ventricular septal defect associated with aortic regurgitation.

Abstract

Hemodynamics, angiocardiography, electrocardiography, and vectorcardiography were analysed in 15 cases of ruptured aneurysm of the sinus of Valsalva and in 20 cases of ventricular septal defect with aortic regurgitation. (1) Systolic pressure in the pulmonary artery and ratio of pulmo-nary to systemic blood flow (Qp/Qs) is well related with anatomical findings in ruptured aneurysm of the sinus of Valsalva, whereas not in ventricular septal defect with aortic regurgitation. (2) Severity of aortic regurgitation is well related with that of ventricular septal defect and pulmonary stenosis in ventricular septal defect with aortic regurgitation. (3) Rv5+Sv1 is well correlated with Qp/Qs in ruptured aneurysm of the sinus of Valsalva, and with degree of aortic regurgitation in ven-tricular septal defect with aortic regurgitation. (4) Terminal vector in horizontal plane is located at right posterior quadrant in ruptured aneurysm of the sinus of Valsalva, whereas at left posterior quadrant in ventricular septal defect with aortic regurgitation.
