Right cardiac obstruction (without shunt)

Obstructions, i.e. obstructions of the passages, can occur at various levels in the right side of the heart or in the pulmonary outflow path. Pure obstructions do not result in a mixing of the blood but a massive additional strain on the cardiac muscles because they have to pump against increased resistance.


Pulmonary stenosis (PS)

Isolated PS occurs with a frequency of 9% of all congenital cardiac abnormalities and, combined with other cardiac abnormalities, with a frequency of nearly 21%.

All forms lead to a hindrance of blood flow ejection from the right ventricle to the pulmonary artery. Depending on how big the stenosis is, a pressure stress and a compensatory hypertrophy of the right ventricle develop.

Constrictions in the region of the right ventricular outflow or of pulmonary arteries can occur at various levels.

Tricuspid stenosis

It is corrected by a commissurotomy (expansion) of the valve opening rims.
