Subepicardial left ventricular aneurysm with an intraventricular narrow neck on the avascular apical area: report of a case.
A 48-year-old hiatus hernia patient with a history of an occasional epigastric burning sensation for the last 10 years presented with a new onset of chest pain in addition to the persistence of his other symptoms. An apical left ventricular aneurism was found on 64-slice computed tomographic angiography. Coronary angiography confirmed the diagnosis. No coronary lesion was found and the apical region of the left ventricle was avascular. He was operated on under the suspected preoperative possible diagnoses of left ventricular apical aneurysm, a pseudoaneurysm, or a diverticulum. Macroscopically, a subepicardial whitish aneurysmal region with a weakened wall was seen at the apical part of the left ventricle. The size of the lesion was 3 x 3 cm. The aneurysm did not have an extracardiac neck. When the aneurysm site was opened, a sclerotic aneurysm wall and a narrow neck below the incised sac was found; and the neck was communicating with the left ventricular cavity. The aneurysm site was resected and closed with a linear closure technique by using pledget-supported sutures. The termination of cardiopulmonary bypass was uneventful. The patient left the intensive care unit on the first postoperative day and was discharged from hospital on the 4th postoperative day. A subepicardial left ventricular aneurysm should therefore also be considered in the differential diagnosis of atypical chest pain.
