Echocardiographic findings in Friedreich's ataxia
Insights
Friedreich
Area of Science:
- Cardiology
- Neurology
- Genetics
Background:
- Friedreich's ataxia is a rare inherited disorder.
- Cardiac involvement is a known complication of Friedreich's ataxia.
Purpose of the Study:
- To investigate the prevalence and characteristics of cardiac abnormalities in patients with Friedreich's ataxia.
- To describe specific echocardiographic findings in this patient cohort.
Main Methods:
- Echocardiographic examinations were performed on 21 patients diagnosed with Friedreich's ataxia.
- Patient ages ranged from 7 to 28 years.
- Cardiac structures and function were assessed.
Main Results:
- Cardiac abnormalities were detected in 90% of patients.
- Common findings included septal hypertrophy (81%), left ventricular free wall hypertrophy (61%), and reduced left ventricular internal dimension (57%).
- Asymmetric septal hypertrophy (ASH) was observed in 29%, and systolic anterior motion (SAM) of the mitral valve in three patients.
Conclusions:
- Echocardiography reveals a high prevalence of cardiac abnormalities in Friedreich's ataxia patients.
- Hypertrophic changes, particularly asymmetric septal hypertrophy, are characteristic.
- Regular cardiac screening is essential for managing Friedreich's ataxia.
Abstract:
Echocardiographic examination of 21 patients with Friedreich's ataxia (age 7 to 28 years) showed cardiac abnormalities in 90% of the cases. They were characterized by varying degrees of septal hypertrophy in 81%, left ventricular free wall hypertrophy in 61%, and a slight reduction of left ventricular internal dimension in 57% of the cases. Asymmetric septal hypertrophy (ASH) with a septal/left ventricular free wall ratio of over 1.3 was found in 29% of the cases, and systolic anterior motion (SAM) of the mitral valve in three patients. Two other patients showed evidence of a different type of cardiomyopathy with marked symmetric left ventricular hypertrophy and marked left ventricular enlargement.

TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
