Overview
Majority of patients with mild pulmonary regurgitation (PR) are asymptomatic and have a benign course, not progressing to chronic PR. Patients tolerate severe chronic PR for a long period of time and begin to develop symptoms when the right ventricle function begins to decline. Chronic severe PR leads to progressive dilation and systolic dysfunction of the right ventricle resulting in symptoms.[1] Complications which may result from pulmonary regurgitation include progressive right ventricular dilatation, heart failure, tricuspid regurgitation, ventricular arrythmias, and sudden cardiac death. Symptomatic patients are treated with pulmonary valve replacement and have a good prognosis.[2]
Natural History, Complications, and Prognosis
Natural history
- MIld PR[1]:
- Acute worsening of PR:
- Patients with acute worsening of PR should be evaluated for associated conditions such as pulmonary hypertension which increase the pressure gradient.
- Chronic PR[3]:
- Patients tolerate severe chronic PR for a long period of time and begin to develop symptoms when the right ventricular systolic function begins to decline or marked dilatation occur. In a symptomatic patient RV dysfunction has usually become irreversible.
- Chronic severe PR leads to progressive dilation and systolic dysfunction of the RV(right ventricle) resulting in symptoms.
- Isolated congenital PR[4]:
- Post TOF repair[5][6]:
- Among patients with TOF repair, symptoms may develop at an early age. Thie finding is partly attributed to the effect of associated lesions on myocardial function. Post complete TOF repair, impaired exercise capacity is directly related to the degree of residual PR.
- The severity of PR after TOF repair can increase over time. The data is supported by experimental[7][8] and clinical[9] evidence.
Complications
- Common complications of pulmonary regurgitation (PR) include:[10][11][12][13][14][6]
- Progressive right ventricular(RV) dilatation
- RV dysfunction
- Heart failure (HF): Exercise intolerance is one of the features of HF. To read about the degree of HF and its manifestations according to NYHA classification click here.
- Tricuspid regurgitation
- Ventricular arrhythmias (such as ventricular tachycardia)
- Sudden cardiac death: In patients with repaired TOF, pulmonic regurgitation is a major hemodynamic lesion associated with ventricular tachycardia and sudden cardiac death.
- Hepatic congestion may develop secondary to right heart failure. Hepatic dysfunction may ensue thromboembolic events.
Prognosis
- The prognosis of pulmonic regurgitation depends on the severity of the condition, etiology and associated complications.[15]
- Mild to moderate PR is not associated with shortened survival.[15]
- The prognosis of symptomatic patients of PR is good after pulmonary valve replacement.[2] Surgical Pulmonic Valve Repair (PVR) improves right ventricular filling and increases left ventricular stroke volume.[16] Ten year overall and event-free survival after PVR is 98% and 70%, respectively.[17]
- Among patients with pulmonary hypertension (PAH), the severity and duration of PAH determines the ultimate prognosis.
- The prognosis of PR due to congenital absence of pulmonic valve is poor and may limit patient's life expectancy in the absence of valve replacement. Absent pulmonary valve (APVS) is associated with severe regurgitation and complications secondary to respiratory distress.[18]
- Higher pre-operative RV end-systolic volume index (ESVI) is the only independent risk factor for suboptimal outcomes post pulmonary valve replacement.[17]
