Flap defects / Repetitorium

Expected terms: anatomy and function valve,  Starling's heart law.


 * Causes:
 * congenital valve disorders,
 * acquired valve disorders (endocarditis),
 * changes in the diameter of the mouth.


 * 2 types
 * 1) Stenosis – increase in resistance, prolongation of systole, reduction of expelled volume
 * Compensation – increase in enddiastolic volume of the section before stenosis, increase in contraction strength, higher excretion pressure, muscle hypertrophy – but heart resistance work, pressure drop after stenosis, possibility failure.
 * 1) Insuficiency – inefficient regurgitation, increase of end-diastolic volume of the partition before the insufficiency valve, increase in contraction strength.
 * Compensation – increased systolic volume but increased volume work, hypertrophy, possibility failure.
