Pulmonic regurgitation differential diagnosis

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
