Rare case describes coexisting mitral valve dysplasia, LVNC, and papillary muscle hypertrophy.
Case Report (n=1)
This case highlights a rare presentation of three coexisting cardiac abnormalities: mitral valve dysplasia, left ventricular non-compaction, and papillary muscle hypertrophy.

May prompt screening for LV non-compaction in mitral dysplasia; leaves open whether papillary muscle hypertrophy marks an early phenotype.
Mitral valve dysplasia is a rare congenital etiology of primary mitral valve regurgitation. It can cause severe chronic mitral regurgitation, which may eventually lead to left atrial and ventricular dilation and dysfunction. Left ventricular non-compaction is a relatively rare cardiomyopathy that overlaps with hypertrophic and dilated cardiomyopathy. It can also lead to left or right ventricular dysfunction and failure. Papillary muscle hypertrophy may be a subtype of, or an early expression of, hypertrophic cardiomyopathy. Herein, we present a 42-year-old woman with a rare coexistence of mitral valve dysplasia, non-compaction left ventricular cardiomyopathy, and papillary muscle hypertrophy.

Yadollahi et al. (2026) conducted a case report in Mitral valve dysplasia, left ventricular non-compaction cardiomyopathy, and papillary muscle hypertrophy (n=1). A 42-year-old woman presented with a rare coexistence of mitral valve dysplasia, non-compaction left ventricular cardiomyopathy, and papillary muscle hypertrophy.
