TR with a 45 mmHg estimated systolic pulmonary artery pressure (PAP) (Figure 1A, 1B). The tricuspid leaflets had no organic pathology, so the severe TR was thought to be secondary to annular dilatation.

Diastolic pressures of both ventricles were elevated and equalized, with a prominent deep and plateau pattern (Figure 2A-2C). Although respiratory ventricular discordance was negative, all of the other catheter findings were consistent with constrictive pericarditis (Figure 2D).

There was also no respiratory variation in mitral and tricuspid inflow velocities (Figure 3).
