Pulmonary stenosis (PS) obstructs the blood flow from the right ventricle (RV) into the pulmonary bed, resulting in a pressure gradient greater than 10 mmHg across the pulmonary valve during systole. In 80% to 90% of all cases PS is found at the level of the valve, but it can also occur below the level of the valve or distally in the...Athenahealth, Inc., 2019
