Monitoring systemic ventriculoarterial coupling after cardiac surgery using continuous transoesophageal echocardiography and deep learning
Authors' conclusion
In conclusion, continuous monitoring using autoMAPSE in the first two postoperative hours reflected ventriculoarterial coupling as well as peak ProBNP and TnT during the subsequent 24 h.
Study context
- Population
- Patients immediately after cardiac surgery monitored with continuous TOE and deep learning (autoMAPSE)
- Participants
- 50 participants
- Outcome
- Relationship between autoMAPSE and ventriculoarterial coupling (Ea/Ees-ratio) and postoperative cardiac biomarkers
- Follow-up
- First 120 min after surgery
Main finding
As reported in the abstract
Correlations of autoMAPSE
autoMAPSE vs Ea/Ees-ratio, rho
- 0.61
autoMAPSE vs peak postoperative ProBNP, rho
- 0.46
autoMAPSE vs peak postoperative troponin-T (TnT), rho
- 0.29
Observational data: associations, not effects.
