Cardiac angiographic findings in Friedreich's ataxia.

Angiograms of 12 patients with typical Friedreich's ataxia were analyzed. The results corroborate previous reports and justify the conclusion that the cardiomyopathy is of the hypertrophic type. In 10 of 12 cases, the hypertrophy is concentric, and non obstructive. Less frequently (2 cases), this hypertrophy is accompanied by diffuse hypokinesis and depressed ejection fraction.
