Case report: echocardiographic observations in patients with Friedreich's ataxia.
Echocardiography was performed on 11 patients with Friedreich's Ataxia. Eight of 11 had asymmetric septal hypertrophy and systolic anterior motion of the anterior leaflet of the mitral valve at rest or after inhalation of amyl nitrite. Two patients had concentric left ventricular hypertrophy. In view of this high incidence of hypertrophic cardiomyopathy, echocardiography is suggested as part of the routine evaluation of the patient with Friedreich's Ataxia.
