However, there can be symptomatic cases. For example, a systolic ejection murmur, often accompanied by or without a systolic click, can be heard with a stethoscope. Patients may also feel tired easily (especially during physical activity), breathing difficulties (particularly during exertion),

When pulmonic stenosis (PS) is present, resistance to blood flow causes right ventricular hypertrophy. If right ventricular failure develops, right atrial pressure will increase, and this may result in a persistent opening of the

discomfort in the chest and lungs, and some individuals may also experience fainting episodes. In severe cases, patients may experience bluish or greyish skin due to low oxygen levels, especially in babies with critical PS.

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 left ventricle) and back into the lungs.

Some individuals with mild PS may not experience any symptoms. Mild PS is generally a benign condition that requires regular cardiac follow-up but no specific therapy.
