Observational Study
The effect of pericardial incision on right ventricular systolic function: a prospective observational study.
Echocardiographic longitudinal markers of right ventricular (RV) systolic function are commonly depressed after coronary artery bypass graft surgery (CABG) despite an uncomplicated course and good clinical recovery. The exact timing and cause of these changes is unknown. The aim of this observational study was to monitor echocardiographic markers of RV systolic function intraoperatively during CABG. We used angle-independent speckle tracking to measure the primary endpoints of tricuspid annular plane systolic excursion (TAPSE) and tricuspid annular systolic velocity (S') before and after pericardiotomy. ⋯ Pericardial opening and suspension had no significant effect on the indices of RV systolic function derived from speckle tracking or colour tissue Doppler.
