ObjectiveThe evaluation of right ventricular systolic function is essential to the hemodynamic management of critically ill cardiac patients. Nevertheless, assessment of right ventricular function remains problematic. We sought to analyze the correlation between tricuspid annular plane systolic excursion (TAPSE) and right ventricular ejection fraction (RVEF) in the assessment of global and regional right ventricular function, respectively.MethodsThis was a prospective study of 61 cardiac surgical patients. TAPSE was measured with transthoracic echocardiography and RVEF was obtained by a thermodilution pulmonary artery catheter. Both measurements were estimated simultaneously during the early postoperative period. Patients with previously identified severe tricuspid insufficiency were excluded from the study to avoid confounding results.ResultsThe etiologies for cardiac surgery were surgical pulmonary thromboendarterectomy in 19 patients, valve replacement in 17 patients, heart transplant in 13 patients, and coronary artery bypass graft in 9 patients. Mean RVEF and TAPSE were 26.2% ± 9.7% and 11.4 ± 4 mm, respectively. RVEF and TAPSE showed a significant correlation (r = 0.73, P < .001). Weak reverse relationships between TAPSE or RVEF with afterload hemodynamic parameters, mean pulmonary artery pressure, or pulmonary vascular resistance were elucidated.ConclusionsTAPSE is a robust measure of right ventricular function that correlates with RVEF assessed by pulmonary artery catheter. A noninvasive method such as echocardiography can guide and support invasive monitoring of right ventricular function in cardiac surgical patients.Copyright © 2016 The American Association for Thoracic Surgery.
