An Unusual Morphological Variant Accessory Posteromedial Papillary Muscle with Accessory Leaflet of Tricuspid Valve in Right Ventricle in An Adult Cadaver in Middle East – A Case Report

Dr Shweta Chaudhary

Abstract :

Papillary muscles are part of the myocardium and are very important in the proper functioning of the atrioventricular valve. Here we describe a rare finding of accessory posterolateral papillary muscle with an accessory leaflet of tricuspid valve in right ventricle of an adult female cadaver. Such variation has not been reported in past in this region. They may causes tricuspid regurgitation due to improper closure or may be an etiological factor for pulmonary and tricuspid stenosis. Their presence may lead to multiple waves during investigative procedures without any clinical symptoms and therefore may lead to misdiagnosis. Awareness of such variations is extremely important in cardiac surgery techniques, prognosis in the repair of the tricuspid valve replacement, regurgitation, pulmonary stenosis and right ventricular outflow tract obstruction and in various valvular graft surgeries
