Noncompaction cardiomyopathy biopsy

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

Both skeletal and cardiac biopsies may reveal abnormal histologic findings.

Skeletal Biopsy

A skeletal biopsy can be performed which may demonstrate inclusion bodies or myopathic changes ^[1].

Cardiac Biopsy

Interstitial fibrosis was observed in 5/5 patients with isolated noncompaction cardiomyopathy who underwent right ventricular biopsy^[2]
Endomyocardial thickening and subendocardial fibroelastosis was observed in 3/5 patients who underwent right ventricular biopsy.
Myocyte necrosis has been observed in areas of trabeculation ^[3]^[4].
