Cardiac complications are common in myotonic dystrophy type 2 (DM2). This case highlights left ventricular non-compaction as a potentially overlooked cardiac issue in DM2 patients, emphasizing the need for awareness and neurological screening.
Area of Science:
- Cardiology
- Neurology
- Genetics
Background:
- Cardiac involvement is frequent in myotonic dystrophy type 2 (DM2).
- Dilated cardiomyopathy and severe arrhythmias are known cardiac complications.
- Left ventricular non-compaction (LVNC) is a cardiomyopathy associated with neuromuscular disorders.
Observation:
- A 61-year-old man with DM2, initially suspected of having dilated cardiomyopathy, was diagnosed with LVNC.
- Echocardiography revealed characteristic LVNC patterns, confirmed by MRI.
Findings:
- The study identifies LVNC as a potential cardiac manifestation in DM2 patients.
- Diagnosis of LVNC can be overlooked in the context of DM2.
Implications:
- Physicians must consider LVNC in DM2 patients presenting with cardiac symptoms.
- Routine neurological examinations are recommended for individuals diagnosed with LVNC to identify potential underlying neuromuscular conditions like DM2.
