Abstract

The right atrioventricular valve (tricuspid valve) allows blood to flow from the right atrium down into the right ventricle. Tricuspid valve disease is rare, but includes tricuspid valve regurgitation, stenosis, and Ebstein anomaly. During regular dissections for undergraduate medical students, in the department of Anatomy, Kasturba Medical College, Manipal, we observed the following variations in the heart in an adult male cadaver. The right atrioventricular valve showed four cusps instead of usual three cusps, anterior, posterior, septal. The extra cusp was anterolateral in position. This variation is important for the cardiothoracic surgeon.
