Flap defects / Repetitorium

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

  • 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.
  2. 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.

Atrioventricular valves
Stenosis Insufficiency
  • reduced blood transfer to the chamber
  • increased filling of halls
  • increase in pressure in the atrium
  • congestion in the relevant venous riverbed before the broken valve
  • edema
  • regurgitation of part of systolic volume
  • increased volume work of halls and chambers

Semilunar valves
Stenosis Insufficiency
