Tricuspid Regurgitation Improvement in Relation to the Amount of Pulmonary Artery Pressure Reduction

I was interested in the study conducted by dr. zoroufian et al.,1 in which they conclude, “the improvement in tricuspid regurgitation (tr) severity is directly correlated with the amount of pulmonary artery systolic pressure (paps) reduction after mitral balloon valvotomy (mbv)” and propose a moderately sensitive and specific cut-off point for paps change in the prediction of tr improvement. this conclusion is based on the post-mbv result, in which patients with tr severity improvement showed a greater decrease in paps following mbv than did those with unchanged or worsened tr grade (p value < 0.034).
