title: Sudden death associated with hypertrophic cardiomyopathy in an alpaca (Llama pacos).
abstract: A healthy, 3-year-old, intact male alpaca (Llama pacos) died suddenly and unexpectedly and had an unusual pattern of hypertrophic cardiomyopathy that was restricted to the interventricular septal and right ventricular myocardium. Grossly pale areas in the affected myocardium corresponded histologically to thickened and disorganized myofibers with excessive branching and marked nuclear pleomorphism. Mitoses were absent. Inflammation and fibrosis were minimal. A few thickened muscular arteries were scattered in the affected myocardium.
