A case of severe right ventricular obstruction caused by a huge aneurysmal tissue tag is described associated with a perimembranous ventricular septal defect with an infundibular extension. Angiograms and surgical inspection clearly showed that the ventricular septal defect extended into the outlet septum. The distinctive features of this case was the severity of the gradient related to the pec...

Ventricular septal defect (VSD) is the persistence of one or more holes in the septum that separates the left and right ventricles of the heart. The ventricles are a single chamber at about four weeks of gestation but by eight weeks it has been divided into two. Failure of development of any part of the septum results in a defect. It may vary considerably in terms of size and haemodynamic conse...

BACKGROUND Ventricular septal defects are the commonest congenital cardiac malformations. They can exist in isolation, but are also found as integral components of other cardiac anomalies, such as tetralogy of Fallot, double outlet right ventricle, or common arterial trunk. As yet, there is no agreement on how best to classify such defects, nor even on the curved surface that is taken to repres...

The classic findings of a patent ductus arteriosus in a young individual are familiar to most physicians. However, it has been appreciated that several factors, principally pulmonary hypertension or pulmonary artery dilatation in the absence of appreciable hypertension, may significantly alter the classic image and lead to the erroneous diagnosis of ventricular septal defect. In 10 surgically p...

Interrupted aortic arch is a rare congenital malformation of the aortic arch defined as a loss of luminal continuity between the ascending and descending portions of the aorta. In a simple interrupted aortic arch, only a ventricular septal defect and patent ductus arteriosus are observed. We present a rare complex form of type A interrupted aorta with an aortopulmonary window, an atrial septal ...

Between January 1973 and March 1982, 13 patients have been identified who had in addition to a ventricular septal defect, a discrete narrowing of the left ventricular outflow tract. Two patients had tetralogy of Fallot and one a complete atrioventricular canal defect. Two patients had previously undergone repair of a juxtaductal coarctation and one patient banding of the pulmonary artery. Eleve...

A 3-week-old female white Bengal Tiger cub (Panthera tigris tigris) presented with acute onset tachypnoea, cyanosis and hypothermia. The cub was severely hypoxaemic with a mixed acid-base disturbance. Echocardiography revealed severe pulmonic stenosis, right ventricular hypertrophy, high membranous ventricular septal defect and an overriding aorta. Additionally, an atrial septal defect was foun...

IN PATIENTS with ventricular septal defect who are more than 3 or 4 years of age, an open corrective operation may be carried out with minimal risk if the lesion is not complicated by the presence of severe pulmonary hypertension. With surgical technics presently available, however, the closure of a ventricular septal defect in an infant or very young child is associated with considerable hazar...
