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
If pulmonary stenosis is severe, congestive heart failure occurs, and systemic venous engorgement will be noted. An associated defect such as a patent ductus arteriosus partially compensates for the obstruction by shunting blood from the left ventricle to the aorta then back to the pulmonary artery (as a result of the higher pressure in the ...
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 ...
The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved [1]), however most of the time, the right ventricle adjusts to an overload in chronic pressure.
Pulmonic outflow obstruction (Pulmonic stenosis) A harsh murmur usually on left second intercostal space radiating to left neck and accompanied by palpable thrill. It can be distinguished from a VSD (ventricular septal defect) by listening to the S2, which is normal in VSD but it is widely split in pulmonary stenosis. However, VSD is almost ...
The left side of the heart is more muscular than the right side of the heart. It pumps oxygenated blood from the lungs into the aorta to perfuse the rest of the body. [ 4 ] When the heart has to pump against increased resistance, or afterload , as in the case of a ventricular obstruction, it compensates by growing in size.
Common causes include aortic or pulmonary regurgitation and left anterior descending artery stenosis. Mid-diastolic murmurs start after S2 and end before S1. They are due to turbulent flow across the atrioventricular (mitral & tricuspid) valves during the rapid filling phase from mitral or tricuspid stenosis.
Pulmonary valve stenosis on an echocardiogram. The diagnosis of pulmonary valve stenosis can be made using stethoscopic auscultation of the heart, which can reveal a systolic ejection murmur that is best heard at the second left intercostal space. [9] Transthoracic or transesophageal echocardiography can provide a more accurate diagnosis.
