Wall of Cardiac Ventricle (Paries ventriculi cordis)
Educational content only — not medical advice.
Anatomy
The wall of the cardiac ventricle is the muscular boundary of the ventricles of the heart, composed of a thin inner endocardium, a thick middle myocardium arranged in complex helical fiber tracts, and an outer epicardium (visceral serous pericardium). The left ventricular wall is roughly three times thicker than the right, generating high pressure required for systemic circulation.
Clinical notes
Transmural myocardial infarction weakens the ventricular wall, posing a catastrophic risk of acute ventricular free-wall rupture and cardiac tamponade 3 to 7 days post-infarction.
