Why the study?
The study was conducted to evaluate whether intraoperative TEE-derived elevated PASP is independently predictive of significant early morbidity in on-pump CABG surgery.
Does elevated intraoperative TEE-derived PASP (≥35 mmHg) predict early morbidity in patients undergoing on-pump CABG?
Population
Around 54 patients undergoing CABG under CPB in a university hospital
Comparison
PASP ≥35 mmHg vs PASP <35 mmHg
Design
Prospective observational study

Elevated TEE-derived PASP may aid risk stratification in on-pump CABG; hypothesis-generating and requires prospective validation.
Does elevated intraoperative TEE-derived PASP (≥35 mmHg) predict early morbidity in patients undergoing on-pump CABG?
Elevated intraoperative TEE-derived PASP is associated with higher left ventricular filling pressures and early postoperative morbidity in CABG patients, but is not an independent predictor of these outcomes.
