Tricuspid Valve Regurgitation
Our analysis of TVR was somewhat limited by 1 of our patients not having any TVR data included in his pre-procedural echocardiogram and 4 patients not having any TVR data included in their follow-up echocardiograms. For the purposes of statistical analysis, TVR was graded as none, mild, mild-moderate, moderate, moderate-severe, and severe as described in the echocardiogram reports, and these grades were converted to numerical values with 0 representing no TVR and 5 representing severe TVR. Of the 43 patients who were able to be assessed for the effect of their LP on TVR, none of the patients had severe TVR pre-procedurally, and 1 patient was found to have severe TVR on their follow-up echocardiogram (Figure 3). 33% of patients had no change in the TVR grade, 28% had an improvement by 1 grade, 2% improved by 2 or more grades, 23% worsened by 1 grade, and 14% worsened by 2 or more grades. The average change was an increase in TVR by 0.28 grades.
