Differential diagnosis of underlying causes

• Pulmonary hypertension
• Infective endocarditis
• Rheumatic heart disease
• Congenital abnormalities: 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)
• Marfan syndrome
• Syphilis infection
• Trauma from withdrawing a Swan-Ganz catheter with the balloon inflated.
• Following valvuloplasty of pulmonary stenosis
• Absence of the pulmonic valve
• Fenestrations in or redundant leaflets of the pulmonic valve
