Differential diagnosis of underlying causes
Pulmonary hypertension (both primary and secondary pulmonary hypertension can cause insufficiency as a result of dilatation of the valve ring)
Congenital abnormalities (e. g., tetralogy of Fallot, ventricular septal defect, valvular Pulmonic stenosis)
Carcinoid heart disease (the majority of patients with metastatic disease will have both pulmonic stenosis and pulmonic regurgitation)
Trauma from withdrawing a Swan-Ganz catheter with the balloon inflated.
Following valvuloplasty of pulmonary stenosis
Syphilis infection
Absence of the pulmonic valve
Fenestrations in or redundant leaflets of the pulmonic valve
