This article reviews the right atrioventricular and pulmonary valves, along with their anatomic variations as well as the papillary muscles and chordae tendineae of the right ventricle of the human heart. A brief anatomical background is given for every structure, as well as a gross review of their embryological basis. Although the normal morphology of the right atrioventricular valve is tricus...

Pediatric intervcntional cardiology was conceived in the 1960s by Dr. William Rashkind, emerged as a distinct suhspccialty during the 198Os, and has come of age in the 1990s. At C.S. Mott Children’s Hospital, the number of interventional pediatric cardiac catheterizations has grown rapidly during the past decade (Fig. 1). Therapeutic procedures currently comprise 35%-40% of all cardiac catheter...

Dilation of blood vessels transluminally was demonstrated by Dr Andreas Gruntzig in 1978. In 1982, Kan demonstrated that congenitally stenosed valve can be dilated with the use of cylindrical balloon and opened up new vistas in the non-surgical treatment of congenital heart lesions. Rapid progress has been now made in (1) Understanding of mechanism of success or failure of balloon dilation (2) ...

The cardiac abnormality most frequently found in rubella syndrome is a combination of branch pulmonary artery stenosis and patent ductus arteriosus, though isolated branch pulmonary artery stenosis is twice as common as isolated patent ductus arteriosus [1]. However, a wide variety of cardiac malformations may be produced, such as ventricular and atrial septal defects, stenosis of the pulmonary...

The feasibility of using balloon dilatation to relieve stenosis caused by dysplasia of the pulmonary valve was assessed in seven patients (five female, mean age two years) with angiographically confirmed dysplasia who were identified among 38 patients with pulmonary valve stenosis selected for balloon dilatation over a two year period. The clinical features in three patients were consistent wit...

Aortic valve stenosis is the obstruction to outflow from the left ventricle because of an abnormal aortic valve. The discharge restriction to the systemic ventricle may also be produced by an anomaly at a sub or supravalvar level. Nevertheless, the most common site of occurrence is by far the annulus (70%). Although congenital aortic stenosis is frequently associated with other significant card...

Double orifice mitral valve (DOMV) is an uncommon congenital heart defect. The isolated occurrence of this anomaly is very rare and, more often, is associated with another congenital malformation, dominated by atrioventricular canal defects (AVCD). Mitral insufficiency and/or stenosis may complicate this malformation. Treatment may be summarized as abstention, surgical valve repair, or valve re...

A 16-year-old male patient who underwent bilateral modified Blalock-Taussig shunt operation at the age of 6 was admitted to our clinic with cyanosis. The oxygen saturation was 60% at time of admission. Echocardiography and computed tomography revealed situs solitus dextrocardia with concordant atrioventricular (AV) discordant ventriculoarterial relation and obstructed bilateral Blalock-Taussig ...
