15. THE PATHOGENESIS OF ATHEROSCLEROSIS Schematic longitudinal section of an artery showing different stages of atherosclerotic plaque vulnerability: A, Normal; B, Rupture-prone plaque; C, Plaque rupture with fissure; D, Critical stenosis; E, Erosion-prone plaque; F, Intra-plaque hemorrhage.
21. Valvular stenosis a narrowing, stiffening, thickening, fusion or blockage of one or more valves Valvular regurgitation blood leakage back in the wrong direction because improperly valve’s closure Valve prolapsed Valvular Heart Cardiac Disease http://www.heartlibrary.com/heart-library-heart-valve-repair-replacement.aspx
When the atrtiums are compressed and the ventricles are filled with blood it is called diastoly and when the ventricles are compressed and flow is pushe away, it is called systole.
After the operation, the patient will spend 7 to 10 days in the hospital, the first 1 to 3 days in an intensive-care unit (ICU). Chest tubes will be in place for the first 2 to 3 days to drain any residual blood and fluid from around the heart. Heart functions will be monitored. The full benefits from the operation may not be ascertained until 3 to 6 months after surgery. Sexual activity may be resumed 3 to 4 weeks after surgery. All activities that do not cause fatigue are permitted, but the patient must not strain the healing chest bone (sternum).
