Epidemiology and Demographics
Classification
Causes
Pulmonary regurgitation can be caused by a variety of congenital and acquired causes:
Congenital Causes:
- Quadricuspid or Bicuspid valves hypoplasia
- Post-repair of tetralogy of Fallot
- Prolapse of the pulmonary valve
Acquired Causes:
- Infective endocarditis
- Rheumatic heart disease
- Carinoid Syndrome
- Myxomatous Degeneration of the pulmonary valve.
Chronic Pulmonary regurgitation is caused by the following:
- Following repair of tetralogy of Fallot
- Following balloon or surgical valvulotomy or valvuloplasty for pulmonary stenosis
- Absent pulmonary valve syndrome
- Isolated congenital PR
- Peripheral pulmonary artery stenosis
- Pulmonary hypertension
- Right ventricular outlet aneurysm
Acute pulmonary regurgitation is caused by the following causes, which include:
- Neonatal Ebstein’s anomaly
- Following balloon dilation of critical pulmonary stenosis
- Perforation of valvar pulmonary atresia
