Aneurysm of the membranous portion of the ventricular septum

Abstract Two cases of aneurysm of the membranous portion of the ventricular septum are presented. This brings the total number of reported cases to 110. Both patients were asymptomatic and the clinical findings were those of coexisting ventricular sepal defect. The diagnosis was established on cardiac catheterization and selective angiocardiography with injection of dye into the left atrium or left ventricle. The anomaly was confirmed at surgery and corrected successfully in both cases.

Clinical and hemodynamic findings following calf aortic valve transplantation for human aortic valve: A preliminary report

Abstract Calf aortic valve transplantation for the human aortic valve has been performed in 20 patients and the patients have been followed up to nine months. The condition of all surviving patients showed improvement as indicated by symptomatic relief, reduction in heart size and auscultatory changes. The hemodynamic studies revealed no aortic valvular gradient at rest. The valve was competent in all but 2 in whom it was of little dynamic significance. Left ventricular performance improved. There was no thromboembolism related to the heterograft. No evidence of host rejection was demonstrated. Our continued use of calf aortic valve is based on its easy availability and favorable short-term results of heterotransplantation. Further investigation will be made to determine its long-term results and ultimate fate. No claim is made as to its superiority over valve prosthesis or homograft until such time when long-term follow-up indicates so. It is speculated that relative deepness of the cusps of the calf aortic valve may allow more surface area of contact between the cusps than those of the human aortic valve. It is hoped that this may minimize the incidence of aortic regurgitation, should the valve cusps retract.

What happens to aortic regurgitation after mitral commissurotomy

a patient with acquired multivalvular lesions, one is faced with a problem of deciding whether or not correction of one lesion initially would improve the patient’s condition sufficiently to reduce the risk of subsequent operation upon the remaining valvular defect, should this be necessary. The decision is certainly difficult to make, since amelioration of one lesion may result in accentuation of the other.6 Thus in cases of mitral stenosis associated with aortic

Clinical and Physiologic Evaluation of Residual Ventricular Septal Defects

Improvements in anesthesia, extracorporeal perfusion, surgical techniques and increasing knowledge of pathologic anatomy and physiology have resulted in a steady reduction of the mortality rate of open heart repair of ventricular septal defects. In addition, the incidence of iatrogenic heart block and residual or recurrent ventricular septal defects have likewise been reduced. 1-8 Despite the above improvements, a certain percentage of residual or reopened shunts occur. It is therefore important to determine the predisposing factors favoring their occurrence. It is the purpose of this paper to determine the incidence of residual ventricular septal defects (RVSD) and its relation to the preoperative hemodynamic data, method of repair and size of the defect estimated at the time of surgery.
