Perioperative Management and Diagnostic Dilemma in a Rare Case of Traumatic Papillary Muscle Rupture with Severe Mitral Regurgitation: A Case Report.

Traumatic papillary muscle rupture is an uncommon cause of acute mitral regurgitation (MR). We report the perioperative management of a case of severe MR due to the posteromedial papillary muscle rupture in a 33-year-old man who had blunt chest trauma caused by fall of an electric lamp post over him. He also had an additional finding of a Ventricular Septal Defect (VSD). He successfully underwent a mitral valve replacement (MVR) with a VSD repair surgery and was discharged on the sixth day of the surgical correction. Sometimes respiratory symptoms because of hemothorax, rib fractures can mask the cardiac trauma and pose diagnostic dilemma. Careful examination and imaging of the heart can detect a serious problem to address it.
