Abstract
A 70-year-old man with partial hypoplasia of the left ventricle, rudimentary right coronary artery and partially fused kidneys was presented. The case had normal blood pressure and left axis deviation in electrocardiogram and died of cerebral thrombosis and pneumonia. Autopsy revealed a localized hypoplasia of myocardium at the anterior wall of left ventricle, rudimentary right coronary artery, thin-walled dilated circumflex coronary artery, thin-walled aorta and a butterfly-shaped fused kidney with another small accessory kidney at its left uppe pole.
Comparison was made with the single coronary artery and the hypoplasia of the aortic tract complexes from the view points of morphology and associated anomalies and a possibility of adult conversion of hypoplasia of the aortic tract complex was suggested. An explanation for the left axis deviation was also given.
