Presentation transcript:

Hypertrophic cardiomyopathy Hypertrophic cardiomyopathy. This heart is from a 31-year-old woman who died suddenly. A, The interventricular septum is notably thicker than the lateral wall. The tan discoloration is the result of fibrosis, which is commonly noted microscopically in these patients. B, The characteristic myocardial disarray of hypertrophic cardiomyopathy. The myocytes are oriented perpendicular to each other, and also appear in a whorled or pinwheel pattern. These patients have cardiac diastolic dysfunction and are at risk for lethal arrhythmias.
