Abstract
- A 47-year-old man presented with complaints of chest pain and dyspnea caused by deceleration injury due to an automobile accident. Systolic cardiac murmur was audible at the right sternal border. An electrocardiogram showed sinus tachycardia. Transthoracic echocardiography revealed a flailing anterior leaflet of the tricuspid valve, papillary muscle rupture, and severe valve insufficiency. Rupture of papillary muscle of the anterior leaflet and chordae tendineae of the posterior leaflet were confirmed by right atrial incision under routine cardiopulmonary bypass. Artificial chordae tendineaes were implanted between the anterior and posterior leaflet and papillary muscles in the right ventricles. De-Vega annuloplasty was also added. This is a very rare case in which a surgery was done for tricuspid valve regurgitation caused by post-traumatic papillary muscle rupture.
