Key result
Robot-assisted closed-chest epicardial 13MHz ultrasound accurately detected anastomotic errors, requiring a median scan time of 176s compared to 125s for open-chest scanning (P=0.01).

Does robot-assisted 13MHz epicardial ultrasound accurately detect construction errors in coronary anastomoses in a porcine model?
Absolute Event Rate: 176% vs 125%
p-value: p=0.01
Robot-assisted closed-chest epicardial 13MHz ultrasound scanning is feasible and accurately discriminates between correctly and incorrectly constructed coronary anastomoses in a porcine model.
Budde et al. (2004) studied Coronary anastomoses construction error (n=8). Robot-assisted closed-chest epicardial 13MHz ultrasound vs. Open-chest manual ultrasound scanning was evaluated on Scan time (seconds) (p=0.01). Robot-assisted closed-chest epicardial 13MHz ultrasound accurately detected anastomotic errors, requiring a median scan time of 176s compared to 125s for open-chest scanning (P=0.01).
