3. Valvular defects of the right heart

Question 1

Tricuspidal insufficiency definition?

Answer 1

Tricuspidal insufficiency is in most cases a relative valvular disorder.

Question 2

Tricuspidal insufficiency can be see in?

Answer 2

It may
be seen in the connection with right cardiac failure with consequent dilatation of the right ventricle.

Question 3

Tricuspidal insufficiency causes?

Answer 3

This situation causes dilatation of the annulus of tricuspidal valve and thus a complete enclosure of
the valve becomes impossible. The right atrium is thin and has a small compensatory ability. It
relatively quickly fails and signes of blood congestion before the right heart develop.

Question 4

Tricuspidal insufficiency- clinical manifestations?

Answer 4

The clinical manifestation of the disease results from stagnation of the blood in the systemic circuit:
increased content of jugular veins, hapatomegaly, hepatojugular reflux, edema, and ascites. Palpably
revealed manifestations include systolic pulsation of the liver which originates by transfer of the
regurgitation wave into hepatic veins.
Hepatocellular icterus arises and symptoms of hemorrhage originates in consequence of
decreased production of blood clotting factors
Dyspepsia
Dyspnea in patients with left ventricular failure.

Question 5

Tricuspidal stenosis?

Answer 5

Tricuspidal stenosis. Tricuspidal stenosis occurs as a consequence of rheumatic fever together with
mitral or aortic valvular defects. Stenotic valve inhibits the inflow of the blood into the right ventricle
during diastole. The blood accumulates in the right atrium which fails. The clinical picture resembles
that of tricuspidal insufficiency. Obstruction of the tricuspidal orifice evokes regurgitation of the
blood from the right atrium into the jugular veins causing thus their pulsation. This state is referred
to as atrial venous pulse.

Question 6

Insufficiency of the pulmonary valve?

Answer 6

Pulmonary insufficiency rarely originates on the basis of
rheumatic or bacterial endocarditis. Predominantly it occurs as a relative-functional incomplete
enclosure in states with pulmonary hypertension and dilatation of pulmonary arteria

Question 7

Stenosis of pulmonic valve?

Answer 7

It is rare and originates in consequent of rheumatic endocarditis. The
right ventricle becomes hypertrophic.
Right heart failure takes place relatively fast.
