Cardiothoracic & vascular anesthesia
Continuous Right Ventricular Pressure Monitoring in Cardiac Surgery
Authors' conclusion
Elevated RVDPG and RVEDP are common in cardiac surgery. RVDPG and RVEDP before CPB initiation are not associated with RV dysfunction and failure but can be used to diagnose them.
Study context
- Population
- Cardiac surgical patients, tertiary care cardiac institute
- Participants
- 105 patients
- Outcome
- Proportion of patients with abnormal RV early to end-diastole diastolic pressure gradient (RVDPG) and abnormal RV end-diastolic pressure (RVEDP)
- Follow-up
- Before CPB initiation and after CPB separation
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Abnormal RVDPG at baseline
80%
RV end-diastolic pressure (RVEDP) at baseline, mean ± SD (mmHg)
14.2 ± 3.9
Median duration of RVDPG > 4 mmHg, % of intraoperative period before cardiopulmonary bypass (CPB) initiation
50.2%
Median duration of RVDPG > 4 mmHg, % of period after CPB separation
60.6%
Observational data: associations, not effects.
Secondary outcomes
Difficult/complex separation from CPB, right ventricular (RV) dysfunction, RV failure
- Difficult/complex separation from CPB
- 46 (43.8%)
- RV dysfunction
- 18 (38.3%)
- RV failure
- 8 (17%)
Association of abnormal RVDPG before CPB with postoperative outcome
- Abnormal RVDPG before CPB not associated with postoperative outcome
