Cardiac involvement is associated with pulmonic valve stenosis and/or tricuspid insufficiency. (medscape.com)
Pulmonic stenosis refers to a constriction of the pulmonic heart valve through which blood must pass on its way from the heart to the lung. (vin.com)
In pulmonic stenosis, the right ventricular outflow tract is narrowed either at the valve, just before it, or just after it. (vin.com)
The most common form of pulmonic stenosis involves a deformed pulmonary valve in which the valve leaflets are too thick, the opening is too narrow, or the valve cusps are fused. (vin.com)
The right side of the heart eventually becomes thick from all this extra work and a post-stenotic dilation (a large bulging area on the far side of the narrowed valve) results from the high pressure squirt the heart must generates to get blood through the stenosis. (vin.com)
Stenosis happens when the leaflets do not open wide enough and only a small amount of blood can flow through the valve. (wikidoc.org)
It may be a narrowing of the orifice (stenosis) or, on the contrary, the impossibility of complete closure (insufficiency). (ccm.mc)
