Key result
Perioperative screening with modified TEE was associated with lower 30-day mortality (2.2% vs 2.5%; adjusted RR 0.67; 95% CI 0.45-0.98) but not stroke compared to conventional TEE.

Does perioperative screening with modified transesophageal echocardiography reduce 30-day mortality and in-hospital stroke in patients undergoing cardiac surgery?
Perioperative screening with modified TEE during cardiac surgery is associated with a reduction in 30-day mortality compared to conventional TEE, though it does not reduce in-hospital stroke.
May support modified TEE screening to lower mortality in cardiac surgery; leaves open randomized confirmation and stroke effects.
The aim of this study was to investigate the impact of perioperative screening with modified transesophageal echocardiography (A-View method). We compared, in consecutive patients who underwent cardiac surgery between 2006 and 2014, 30-day mortality and in-hospital stroke incidence, operated either with perioperative modified TEE screening (intervention group) or only with conventional TEE screening (control group). Of the 8,605 study patients, modified TEE was applied in 1,391 patients (16.2%). Patients in the intervention group were on average older (71 versus 68 years, p<0.001 ) and more often females (31.0% versus 28.0%, p<0.001 ) and had a higher predicted mortality (EuroSCORE I: 5.9% versus 4.0%, p<0.001 ). The observed 30-day mortality was 2.2% and 2.5% in both groups, respectively, with multivariable and propensity-score adjusted relative risks (RRs) of 0.70 (95% CI: 0.50–1.00, p=0.05 ) and 0.67 (95% CI: 0.45–0.98, p=0.04 ). In-hospital stroke was 2.9% and 2.1% in both groups, respectively, with adjusted RRs of 1.03 (95% CI: 0.73–1.45) and 1.01 (95% CI: 0.71–1.43). In patients undergoing cardiac surgery, use of perioperative screening for aortic atherosclerosis with modified TEE was associated with lower postoperative mortality, but not stroke, as compared to patients operated on without such screening.

Klomp et al. (2017) conducted a cohort in Cardiac surgery (n=8,605). Perioperative screening with modified transesophageal echocardiography (A-View method) vs. Conventional TEE screening was evaluated on 30-day mortality (RR 0.67, 95% CI 0.45-0.98, p=0.04). Perioperative screening with modified TEE was associated with lower 30-day mortality (2.2% vs 2.5%; adjusted RR 0.67; 95% CI 0.45-0.98) but not stroke compared to conventional TEE.
