title: [Ventricular tachycardia caused by a left ventricular aneurysm in a patient with previous surgery for ventricular septal defect].
abstract: Ventricular mural aneurysms especially in the left ventricle represent an increased risk for life-threatening arrhythmias. We present a case of ventricular tachycardia originating from an inferobasal left ventricular aneurysm. A 25-year-old male patient presented with complaints of palpitation, breathlessness, and dizziness of two-hour onset. The electrocardiogram showed wide-QRS tachycardia at which time his blood pressure was 80/40 mmHg. The patient suddenly developed collapse and ventricular tachycardia was diagnosed on the monitor, and he returned to sinus rhythm following successful cardioversion. He remained stable during hospitalization. The electrocardiogram was in sinus rhythm with right bundle branch block and small Q waves in inferior leads. He had an eight-year history of surgery for ventricular septal defect closure, during which a ventricular aneurysm was detected but left untreated. Echocardiographic examination showed a dyskinetic aneurysmal region extending from the inferobasal segment to the posterior wall of the left ventricle. Coronary arteries were normal on angiography, and ventriculography confirmed the aneurysm. Electrophysiologic study was recommended, but the patient refused any treatment. He remained asymptomatic during 18 months of follow-up.
