The diagnosis of PPS murmur usually begins with a routine physical examination. A healthcare provider may detect the murmur during auscultation with a stethoscope. The murmur is often described as a soft, systolic ejection murmur best heard at the upper left sternal border and radiates to the back and axillae. Further diagnostic tools include echocardiography to assess the extent of the stenosis and blood flow through the pulmonary arteries. Additionally, a chest X-ray might be performed to rule out other causes of the murmur.
