Most cardiac aneurysms develop after myocardial infarction. Calcification in the aneurysmal wall is seen rarely. In this case report the authors present a thirty-nine-year-old man, who had been free from symptoms until eight months before, when he began to experience palpitations due to monomorphic sustained ventricular tachycardia. A chest roentgenogram disclosed an oval calcification on the left ventricular apex. Coronary angiography and left ventriculography revealed normal epicardial coronary arteries and a massive calcified and ossified left ventricular apical aneurysm. He had no chest pain, nor were there electrocardiographic findings of myocardial infarction. Attacks of ventricular tachycardia disappeared after aneurysmectomy was performed. To the author's knowledge there is no case report in the literature of a calcified left ventricular aneurysm with normal epicardial coronary arteries and without clinical and electrocardiographic findings of infarction. They discuss the possible etiology of this case.
