Clinical Scorecard: Assessment of Bilateral Radial Arterial Pressure Concordance as a Real-Time Indicator of Cardiac Recovery During Weaning from Peripheral VA-ECMO

At a Glance

Key Highlights

• Bilateral radial arterial pressure monitoring indicates native cardiac recovery.
• Concordance defined as left-right systolic pressure difference < 10 mmHg.
• Sensitivity of bilateral radial pressure-gas concordance for LVOT VTI ≥ 10 cm is 94.4%.
• Bilateral monitoring provides continuous real-time information.
• Helps identify optimal timing for echocardiographic weaning assessment.

Guideline-Based Recommendations

Diagnosis

• Echocardiography is used to evaluate cardiac function during weaning.

Management

• Bilateral radial arterial pressure monitoring may complement echocardiographic assessment.

Monitoring & Follow-up

• Continuous monitoring of bilateral radial arterial pressure and ABG values.

Risks

• Bilateral radial arterial pressure monitoring is not routinely available.

Patient & Prescribing Data

28 consecutive adult patients supported with peripheral VA-ECMO.

Bilateral radial pressure-gas concordance observed in 79% of patients during recovery.

Clinical Best Practices

• Use bilateral radial arterial lines when possible for monitoring.
• Assess concordance of arterial pressure and ABG values as a signal for cardiac recovery.
• Consider echocardiographic assessment when bilateral concordance is observed.
