Evaluation of right ventricular systolic function by the analysis of tricuspid annular motion in patients with acute pulmonary embolism.

ABSTRACT:

Background

Measurement of right ventricular (RV) systolic function is important for patients with acute pulmonary embolism (PE). However, assessment of RV function is a challenge due to its complex anatomy. We measured RV systolic function with analysis of tricuspid annular motion in acute PE patients.

Methods

From August 2007 to May 2011, all consecutive PE patients were prospectively included. Tricuspid annular motion was analyzed with tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular systolic velocity (TASV).

Results

We analyzed total 50 patients (38 females, 68 ± 14 years). Mean RV fractional area change (RVFAC) was 26.2 ± 10.8%; RV Tei index 0.78 ± 0.35; TR Vmax 3.8 ± 0.5 m/sec; pulmonary vascular resistance (PVR) 3.5 ± 1.2 WU. TAPSE was 16
