A pulmonary valve is an insufficient closure of the pulmonary valve, so the flap in the Austreibungsbahn the right ventricle. By Pulmonalklappeninsuffizienz flows during diastole blood from the pulmonary artery ( pulmonary trunk ) into the right ventricle back.
A mild pulmonary valve without clinical signs of heart disease is common and not to be regarded as pathological findings. It is thus referred to as " physiological " pulmonary insufficiency here.
A higher-grade pulmonary valve is often a result of endocarditis. High blood pressure in the pulmonary circulation (pulmonary hypertension ) can occur due to overstretching of the Pulmonalklappenrings relative to valve insufficiency. The return flow of blood leads to a considerably increased volume load on the right ventricle.
The speed of the returning blood is dependent on the pressure difference between the pulmonary artery and right ventricle. It is measured by echocardiography and can be used based on the Bernoulli equation to estimate the pressure in the pulmonary artery.
In contrast to the pulmonary valve, the pulmonary valve is a rare heart defect occurring.
