Dissection of pericardium and heart in situ
Latex cast of cavity of left ventricle; septal branch of left coronary artery
The wall of the left ventricle has been resected to expose the red latex cast which fills the ventricle. The myocardium at one point near the apex measures only 1 mm. in thickness. The conus arteriosus has been removed to demonstrate the origin of the ascending aorta and a large septal branch (11) of the left coronary artery.
