3-2 Echocardiographic and fluoroscopic findings
Obstructive TV thrombosis were found in 65 (97%) based on both
echocardiographic Doppler assessments and leaflet movement in
fluoroscopy. Transesophageal echocardiography (TEE) was performed in 20
(29.8%) episodes. The reductions in the averages of mean gradients and
pressure half-time were significantly different after successful
treatment (p <0.001). Transvalvular leak severity decreased
after thrombolytic therapy, and its changes were statistically
significant (p = 0.013). Decrease in mean inferior vena cava size and
increase in its respiratory collapsibility after treatment were
statistically significant (p = 0.001 and p <0.001,
respectively), revealing decreased RA pressure after treatment. There
were no statistically significant changes in right ventricular (RV)
function, RV peak systolic myocardial velocity (Sm), Tricuspid Annular
Plane Systolic Excursion (TAPSE), and mean pulmonary artery pressure
(mean PAP). First fluoroscopy on admission revealed both leaflets
blockade in 30 (44.7%), one leaflet blockade in 28 (41.8%) and
limitation of motion in 9 (13.4%). Of fixed occluders of TV leaflets,
71.6% were in semi-open position. All measured echocardiographic
parameters before and after treatment were summarized in (Table
