Assessing Right Ventricular Function in the Perioperative Setting, Part II: What About Catheters?

Area of Science:

• Cardiology
• Critical Care Medicine
• Anesthesiology

Background:

• Echocardiography is standard for perioperative right ventricular (RV) function assessment.
• High-risk patients (pulmonary hypertension, RV failure, complex surgery) require enhanced monitoring.
• Echocardiography may be limited in intensive care or specific surgical scenarios.

Purpose of the Study:

• To evaluate the utility of pulmonary artery catheterization (PAC) in monitoring high-risk surgical patients.
• To determine if PAC provides valuable functional data beyond standard echocardiography.
• To assess PAC's role in early detection of right ventricular failure in vulnerable populations.

Main Methods:

• Review of existing literature and clinical guidelines on perioperative RV monitoring.
• Analysis of data from catheter-based techniques, specifically PAC.
• Comparison of information obtained from PAC versus echocardiography in high-risk settings.

Main Results:

• PAC provides continuous hemodynamic and functional data, including cardiac output and RV performance.
• PAC can be valuable in intensive care units and when echocardiography is limited.
• Despite complication risks, PAC aids in early RV failure detection in select high-risk patients.

Conclusions:

• Pulmonary artery catheterization is a valuable adjunct to echocardiography for high-risk surgical patients.
• PAC enables comprehensive hemodynamic assessment and supports timely intervention for RV dysfunction.
• Careful consideration of risks and benefits is necessary when employing PAC in vulnerable patient groups.
