[A case of congenital ventricular diverticula].

Congenital ventricular diverticula are classified into muscular type and fibrous type. Muscular diverticula may be associated with congenital midline thoracoabdominal malformations. Fibrous diverticula, also called congenital ventricular aneurysm, are often seen in black american and South African Bantus, but very few such cases have been reported in our country. A 33-year-old Japanese male was admitted to our hospital for evaluation of chest X-ray and ECG abnormalities. UCG and cineangiography revealed an outpouching of the left ventricle. As it increased in size during the four-year follow-up, surgical resection was performed. The left ventricular diverticulum was multilobular and had a thin wall, which was excised and reconstructed with a patch. There was another small diverticulum on the free wall of the right ventricle, which was directly closed with a mattress suture. A rare case of multiple congenital fibrous ventricular diverticula with successful surgical resection was reported.
