Papillary muscle rupture due to blunt chest trauma

A 23-year-old male patient was referred to our hospital following detection of a cardiac murmur at a center where he had sought treatment for his complaint of dyspnea due to blunt chest trauma of a-month history. Transthoracic and transesophageal echocardiography showed papillary muscle rupture and severe mitral regurgitation. At surgery, it was noted that papillary muscle rupture was accompanied by complete rupture of the chordae tendineae of the anterior leaflet, making reconstruction unfeasible. The valve was excised and a prosthetic valve was implanted.
