Follow-up
Echocardiographic results
In most patients with recent echocardiogram reports, 186 (96.4%) had PR
and 7 (3.6%) were free from PR.
None
of the patients had absence of
tricuspid regurgitation (TR), 136 (70.5%) had mild TR,
51 (26.4%) had mild to moderate TR,
4 (2.1%) had moderate TR, 1 (0.5%) had moderate to severe TR, and 1
(0.5%) had severe TR. Nearly half of the cohort (48.7%) had RV
dilation, 99 (51.3%) had normal RV
size on most recent echocardiogram reports, some had significant right
ventricular enlargement at the beginning, but the extent of the
enlargement gradually diminished during follow-up. In follow-up, the
pulmonary transvalvular peak gradients were dropped obviously. (Table
