Testing clinical selection criteria for intraoperative transoesophageal echocardiography in isolated coronary artery bypass graft surgery

Key Points

  • Of 42,249 patients undergoing isolated CABG surgery in the US, 24 919 (59.0%) received and 17 330 (41.0%) did not receive intraoperative transesophageal echocardiography (TEE).

  • After matching, intraoperative TEE was significantly associated with a lower, 30-day mortality: 2.63% vs 3.20% (odds ratio [OR]: 0.81; 95% confidence interval [CI]: 0.71, 0.92; p=0.002).

  • In the subgroup matched comparisons, intraoperative TEE was significantly associated with a lower, 30-day mortality rate among those with congestive heart failure: 4.20% vs 5.26% (OR: 0.78; 95% CI: 0.66, 0.94; p=0.007) and among those undergoing multivessel CABG with congestive heart failure: 4.23% vs 5.24% (OR: 0.80; 95% CI: 0.65, 0.97; p=0.025).

  • These findings may support prioritized intraoperative TEE allocation to these patient populations at centers with limited TEE capabilities.
