Physiological _'s general knowledge of pathology of tricuspid stenosis
Pathologic physiology
Pathology changes and is similar to mitral stenosis, but it is relatively light to damage. The persons who exist alone of tricuspid stenosis are extremely rare, often accompany and close complete, bicuspid valve and a damage of aorta. Corpse examine the intersection of wind and worry 15% have tricuspid stenosis, but clinical diagnosis person only 5%. Women meet more, the other rare causes of disease have locking and a kind of cancer syndrome of inborn tricuspid valve,etc..
Dynamics of blood flow unusually includes: Rise when relaxation one pigeonhole across tricuspid valve difference, sport and inhale, reduce while exhaling. The average relaxation one presses difference> 1.9mmHg briefs on tricuspid stenosis; >At the 5mmHg, average atrium dextrum pigeonhole, rise to being enough to lead to the fact the venous pressure of the systemic circulation rise notably, intravenous anger one of neck, liver is great, ascites and edema appear. The right ventricle heart arranges blood volume to reduce, does not increase with sport, the right ventricle is normal or reduces in capacity.
