Pulmonary valve stenosis (PVS) is a heart valve disorder. Blood going from the heart to the lungs goes through the pulmonary valve, whose purpose is to prevent blood from flowing back to the heart. In pulmonary valve stenosis this opening is too narrow, leading to a reduction of flow of blood to the lungs. [1] [5]
Pulmonic stenosis is usually due to isolated valvular obstruction (pulmonary valve stenosis), but it may be due to subvalvular or supravalvular obstruction, such as infundibular stenosis. It may occur in association with other congenital heart defects as part of more complicated syndromes (for example, tetralogy of Fallot). [citation needed]
Pulmonary valve stenosis, which is the thickening of the pulmonary valve, therefore causing narrowing; Mitral valve stenosis, which is the thickening of the mitral valve (of the left heart), therefore causing narrowing; Tricuspid valve stenosis, which is the thickening of the tricuspid valve (of the right heart), therefore causing narrowing
Pulmonary (or pulmonic [4]) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent [5] and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole. [6] While a small amount of backflow may occur ordinarily, it is usually only shown on an echocardiogram and ...
Pulmonary artery stenosis (PAS) is a narrowing of the pulmonary artery.The pulmonary artery is a blood vessel moving blood from the right side of the heart to the lungs. . This narrowing can be due to many causes, including infection during pregnancy, a congenital heart defect, a problem with blood clotting in childhood or early adulthood, or a genetic ch
The pulmonary artery's infundibulum's orientation regulates the pulmonary arteries' preferred dilatation as well. Infundibulum is typically vertical and brief. When the infundibulum in APVS is oriented horizontally and to the right, it causes the right pulmonary artery to dilate aneurysmally, further compressing the middle lobe bronchus. A left ...
The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery, and has three cusps. It is one of the four valves of the heart and one of the two semilunar valves , the other being the aortic valve .
The Graham Steell murmur of pulmonary regurgitation, a high-pitched, diastolic, decrescendo blowing murmur along the left sternal border, results from dilation of the pulmonary valve ring and occurs in patients with mitral valve disease and severe pulmonary hypertension.
