Key result
MVR successfully corrects severe MR from traumatic papillary muscle rupture in a 33-year-old patient.
Why the study?
Traumatic papillary muscle rupture is an uncommon cause of acute mitral regurgitation, and accompanying respiratory symptoms from thoracic trauma can mask cardiac injury and cause diagnostic dilemma.
Highlights the importance of careful cardiac imaging in blunt chest trauma to detect rare complications like papillary muscle rupture, which may be masked by respiratory symptoms.
Supports surgical success in traumatic papillary muscle rupture; leaves open optimal diagnostic strategies in blunt chest trauma.
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.
