[Recurrent ventricular tachycardia due to hydatic cyst of the heart. Recovery after surgical resection. Report of one case].

Report of the case-history of a 66 year-old woman in whom the diagnosis of ventricular aneurysm was reached in 1958 during a systematic X-ray examination, while the electrocardiogram suggested a lateral-wall infarction with no anginal pain. After fifteen years of a practically asymptomatic course there were practically uninterrupted attacks of ventricular tachycardia. Coronary angiography and left ventriculography excluded the hypothesis of an aneurysm and suggested the diagnosis to cystic tumour of the left ventricle. A voluminous hydatic cyst was removed surgically. Ventricular arrhythmia did not recur since.
