Overview
Rippling muscle disease (RMD) is a rare skeletal myopathy characterized by visible muscle rippling on physical examination. This condition has been traditionally associated with milder presentations, but a severe autosomal recessive form exists, marked by fatal arrhythmic cardiomyopathy and delayed bone age 1.Diagnosis
Clinical presentation includes muscle rippling and delayed bone age.
Electrocardiogram (ECG) abnormalities may indicate arrhythmic cardiomyopathy.
Genetic testing can identify specific mutations associated with severe forms 1.Management
No specific drug treatments mentioned for RMD in severe forms.
Management of arrhythmic cardiomyopathy may require cardiology intervention, including antiarrhythmic drugs or pacemakers as indicated 1.
Supportive care focusing on symptom management and monitoring cardiac function is crucial 1.Special Populations
Pediatrics: Delayed bone age suggests careful monitoring of growth and development 1.
Comorbidities: Severe forms may predispose patients to fatal cardiac complications, necessitating vigilant cardiac surveillance 1.Key Recommendations
Screen patients with severe RMD for arrhythmic cardiomyopathy using ECG and echocardiography (Evidence: Moderate 1).
Implement multidisciplinary care involving cardiology for managing cardiac complications (Evidence: Expert opinion 1).
Monitor growth and bone development closely in pediatric patients due to potential delays (Evidence: Moderate 1).References
