Overview
In a recent study [1] of 53 patients with non-compaction cardiomyopathy, the first 42 were misdiagnosed with another form of heart disease. Improved awareness and improved imaging modalities allowed the correct diagnosis to be made in the last 11 cases. The most common misdiagnoses included:
- Dilated cardiomyopathy: 30 Cases
- Congenital heart disease: 6 Cases
- Ischemic heart disease: 2 Cases
- Disease of the heart valves: 2 Cases
- Dilated phase hypertensive cardiomyopathy: 1 Case
- Restrictive cardiomyopathy: 1 Case
Given the apical hypertrophy, the disease may also be mistaken for hypertrophic obstructive cardiomyopathy.
The high number of misdiagnosis can be attributed due to non-compaction cardiomyopathy only being first reported in 1990, and so diagnosis is often overlooked or delayed. Advances in medical imaging equipment (Echo and MRI) has made it easier to diagnosis NCC.
