A 30-year-old male patient was admitted to our clinic with the complaints of dyspnea and fatigue. It was found out that two years ago in Ukraine, he had been operated on because of a right ventricular laceration following a stabbed injury and then he had been operated on again because of a ventricular septal defect that was detected in his first postoperative follow- up. On echocardiography, 1 cm defect on the anterior leaflet of the mitral valve, severe mitral regurgitation and patent foramen ovale (PFO) were detected. In our clinic, the defect on the anterior mitral leaflet was primarily repaired with 8/0 prolen and the PFO was closed. No residual regurgitation was traced in the postoperative control echocardiography. This is a rare case in which three different operations were required to repair the injuries in the right ventricle, ventricular septum and the mitral valve. This case stresses both the importance of a team work and the value of echocardiography as an adjunct to the clinical evaluation, in the emergency evaluation of a traumatic patient with a probable heart injury.
