Monitoring right ventricular pressure during cardiac surgery

Early Identification and Prediction of Right Ventricular Dysfunction and Failure in Critically Ill Patients: An Observational Non-Interventional Cohort Study

Observational Montreal Heart Institute · NCT04092855

This study is testing if monitoring right ventricular pressure during heart surgery can help doctors spot problems early and improve recovery for patients aged 18 and older.

What this trial studies

This observational study aims to assess the prevalence of abnormal right ventricular (RV) pressure waveforms in patients undergoing cardiac surgery. By identifying RV dysfunction early, the study seeks to improve patient outcomes through timely interventions. The research will involve monitoring patients in the operating room and intensive care unit to determine the correlation between abnormal RV pressure waveforms and post-operative complications. The study will include patients aged 18 and older who are receiving standard care with pulmonary artery catheters.

Who should consider this trial

Good fit: Ideal candidates for this study are adult patients undergoing cardiac surgery who are monitored with a pulmonary artery catheter.

Not a fit: Patients undergoing emergency surgery or those with specific concomitant diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier detection and intervention for patients at risk of right ventricular dysfunction, potentially reducing post-operative complications.

How similar studies have performed: While the approach of monitoring RV pressure waveforms is not widely reported, the study aims to fill a gap in understanding RV dysfunction in cardiac surgery, suggesting a novel exploration in this area.
