Successful Tricuspid Valve Replacement in a Patient with Severe Pulmonary Arterial Hypertension and Preserved Right Ventricular Systolic Function

Figure 2

(a) Continuous wave Doppler profile of tricuspid regurgitation in the parasternal long-axis view. The tricuspid valve regurgitant velocity is 3.61 m/s. Using the modified Bernoulli equation $(\mathrm{\Delta }P=4V^2)$ and assuming a right atrial pressure of 15 mmHg, the estimated pulmonary artery systolic pressure is 67 mmHg. (b) Tissue Doppler profile of the tricuspid valve annulus demonstrates a systolic velocity of 14.5 cm/sec consistent with preserved right ventricular function [1, 2].
