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.
Aortic valve dysfunction, aortic sclerosis/stenosis; Tricuspid valve in long-axis; Pulmonary valve in long-axis; Right ventricle, including inflow and outflow tracts; Left ventricle in short-axis Closer to the base can reveal the left ventricular outflow tract; At the level of the base can show the movement of the mitral valve leaflets in short ...
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]
Color Doppler (type of echocardiography) measures the degree of pulmonary stenosis. Additionally, close monitoring of the ductus arteriosus is done in the neonatal period to ensure that there is adequate blood flow through the pulmonary valve.
Abbreviations: LV and RV=left and right ventricle, PT=pulmonary trunk, VSD=ventricular septal defect, PS=pulmonary stenosis. Echocardiogram in transposition of the great arteries. This subcostal view shows the left ventricle giving rise to a vessel that bifurcates, which is thus identified as the pulmonary artery.
When the right side of the heart is more underdeveloped than the left side, this is known as hypoplastic right heart syndrome. HRHS is known for the pulmonary valve, the tricuspid valve, right ventricle, and the pulmonary artery all failing to form properly. HRHS also causes the right ventricle to be a fair amount smaller than the left side.
The Melody Transcatheter Pulmonary Valve (TPV), approved in Europe in 2006 and in the U.S. in 2010 under a Humanitarian Device Exemption (HDE), is designed to treat congenital heart disease patients with a dysfunctional conduit in their right ventricular outflow tract (RVOT).
In the first few days, if there is no pulmonary valve stenosis, a pulmonary valve banding is necessary to prevent pulmonary hypertension and the ductus must be kept open to allow blood-flow using medication containing prostaglandin. At same time, if necessary, the atrial and ventricular septum communications must be enlarged.
