Flap defects / Repetitorium
From WikiLectures
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
- 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.
- 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.
