Overview

Chest x ray may not be required for the diagnosis of pulmonic regurgitation (PR). However, lateral and PA view of chest radiograph may help determining the right ventricular enlargement. Right atrial enlargement may also be seen in patients with concomitant tricuspid regurgitation.[1]

Chest X ray

There are no chest x ray findings required for the diagnosis of pulmonic regurgitation. However, lateral and PA view of chest radiograph may help determine the complications and associated conditions of PR, which include right ventricular enlargement. Right atrial enlargement may also be seen in patients with concomitant tricuspid regurgitation.[1]
