Cardiovascular System
Heart, Myocardium - Vacuolation, Cytoplasmic
Narrative




due to disintegration of their outer membranes. In other cases, vacuolation forms from distension of the sarcoplasmic reticulum within cardiomyocytes. Electron microscopic examination may be used to positively identify the source and content of the vacuoles.
