Rheumatic disease causes fusion of the commissures and fibrotic contraction of valve leaflets, commissures, and chordae tendineae. Valve dysfunction is caused by thickening or stretching of the leaflets, resulting in backward blood flow. Calcific degeneration results in fusion of the commissures and fibrous contractures of the cusps and leads to a decreased valve area size and obstruction of left ventricular outflow. Rheumatic disease results in thickened and retracted valve cusps, whereas aortic aneurysm causes annular dilation stenosis problem with opening- blood cant get out insufficiencies problem with closing blood can backflow.
