In aortic regurgitation, the aortic valve is incompetent. Hence, some of the blood which is pumped into the aorta from the left ventricle during systole, falls back into the left ventricle during diastole. The left ventricle has to now work harder to pump out the excess blood and this leads to LVH and eventually LVF. …
Aortic stenosis is narrowing of the aortic valve orifice. Normal aortic valve orifice: 2.5-3.5 sq.cmCritical aortic stenosis: <1 sq. cm Causes of AS:Rheumatic feverCongenital- Bicuspid aortic valveCalcification of the aortic valve (old age) Symptoms (3 cardinal symptoms of Aortic stenosis):1.Exertional dyspnea2.Syncope (due to reduced cerebral perfusion)3.Angina pectoris (due to low cardiac output) SignsLow blood pressure …
In MR, the mitral valves are incompetent.Hence, during ventricular contraction, some blood flows from the left ventricle into the left atrium. Under normal conditions, all the blood from the left ventricle enters into the aorta.

Mitral stenosis Narrowing of the lumen of the mitral valve is mitral stenosis. Normal mitral valve orifice: 4-6 sq.cm Minimal MS: >2 sq.cm Mild MS: 1.5-2 sq.cm Moderate MS: 1-1.5 sq.cm Severe MS: <1 sq.cm Causes: -Rheumatic (most common) -Congenital -Severe mitral annular calcification -Collagen vascular diseases Symptoms: 1.Breathlessness 2 Cough with …
