Overview
Pathophysiology
The left ventricle can be enlarged from two broad underlying conditions: dilation and hypertrophy.
- Left ventricular dilation:
- Can occurs as a result of volume overload. Conditions that cause volume overload can be further broken down as follows:
- Valvular Disease: More common underlying valvular heart disease conditions would include mitral regurgitation and aortic regurgitation
- Congenital Heart Disease: Patent ductus arteriosus and a ventricular septal defect.
- High output states resulting in volume overload: Anemia and thyrotoxicosis.
- High stroke volume states: Complete heart block and prolonged severe sinus bradycardia
- Can occur as a result of ischemia and remodeling
