What is the clinical evidence from this study?

Study design: Observational. Population: Elderly patients undergoing transcatheter aortic valve replacement (TAVR) (n=30). Intervention: ClearSight finger cuff arterial pressure measurement vs. Direct intra-arterial pressure measurement. Primary outcome: Agreement between direct intra-arterial pressure and ClearSight finger cuff arterial pressure measurements (Bias -4.88 ± 15.46 mmHg for SBP, 4.73 ± 8.95 mmHg for mean, and 9.53 ± 9.01 mmHg for DBP).

Why the study?

This study aimed to assess the agreement between direct intra-arterial pressure and ClearSight finger cuff arterial pressure measurements in elderly patients undergoing TAVR.

Does ClearSight finger cuff arterial pressure measurement agree with direct intra-arterial pressure in elderly patients undergoing TAVR?

Population

30 patients aged 65 years and older undergoing TAVR under general anesthesia in Japan

Comparison

Direct intra-arterial pressure vs ClearSight finger cuff arterial pressure measurements

Design

Prospective observational study

Follow-up

30 min after valve deployment

Key result

ClearSight finger cuff arterial pressure measurement showed acceptable agreement with direct intra-arterial pressure in elderly TAVR patients, with a systolic blood pressure bias of -4.88 mmHg.

Authors

Overview

ClearSight shows good agreement with intra-arterial BP in TAVR; leaves open non-invasive monitoring as alternative pending larger validation.

Does ClearSight finger cuff arterial pressure measurement agree with direct intra-arterial pressure in elderly patients undergoing TAVR?

Population

30 patients aged 65 years and older undergoing transcatheter aortic valve replacement under general anesthesia, monitored for 30 minutes post-valve deployment.

Exposure

ClearSight finger cuff arterial pressure measurement recorded for 30 min after valve deployment

Comparator

Direct intra-arterial pressure measurement recorded concurrently

Outcome

Agreement between direct intra-arterial pressure and ClearSight finger cuff arterial pressure measurements assessed by bias and precision (Bland-Altman analysis)surrogate

Main Result

Effect estimate: Bias -4.88 ± 15.46 mmHg for SBP, 4.73 ± 8.95 mmHg for mean, and 9.53 ± 9.01 mmHg for DBP

Non-invasive ClearSight finger cuff arterial pressure monitoring provides acceptable agreement with direct intra-arterial pressure in elderly patients undergoing TAVR, offering a potential alternative for hemodynamic monitoring.
