[A case of an expanding congenital left ventricular aneurysm].

Congenital ventricular aneurysm is rare. There have been only 17 case reports in Japan. Only 9 of them were treated surgically. In this paper, we report a case with a congenital left ventricular aneurysm successfully treated by surgery. A 42-year-old female was admitted to our hospital with chest pain and ECG abnormalities. Left ventriculography revealed aneurysmal formation of the left ventricle with normal coronary arteries. Surgical resection was performed because repeated echocardiography had showed its enlargement. Surgical treatment for congenital ventricular aneurysm seems to be indicated to those with worsening symptoms, volume enlargement or thrombus formation.
