Moderate tricuspid regurgitation was recorded (Figures 1(a) and 1(b)).
Systolicpulmonary artery pressure (SPAP). Continuous-wave Doppler echocardiography was used to estimate SPAP.

Right ventricular systolic pressure was calculated to be 60 mmHg (Figure 2).

Continuous Doppler showed the presence of a mean midventricular gradient of 53 mm Hg and a peak gradient of 125 mmHg, a peak velocity of 5.5 m/s, and the presence of relaxation diastolic dysfunction (Figure 3).
