Overview
Natural history
- Mild PR is a very common finding on 2D echo.[1]
- Majority of patients with mild PR are asymptomatic and have a beningn 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.
- Patients with acute worsening of PR should be evaluated for associated conditions such as pulmonary hypertension which increase the pressure gradient.
