YES, YOU CAN USE THE TRICUSPID REGURGITATION SIGNAL FOR THE RIGHT VENTRICULAR TO RIGHT ATRIAL GRADIENT, NO MATTER HOW SEVERE THE TRICUSPID REGURGITATION: A SIMULTANEOUS ECHOCARDIOGRAPHY: CATHETERIZATION STUDY

The performance of the modified Bernoulli equation to estimate the RV-RA pressure gradient by continuous wave Doppler in severe tricuspid regurgitation (TR) is not known. Simultaneous continuous wave (CW) Doppler of the TR jet was prospectively obtained at time of cardiac catheterization in...
