Non-invasive measurements of cardiac output (4.1 vs. 4.8 L/min, p = 0.03) and cardiac index (2.2 vs. 2.7 L/min/m2, p = 0.01) were significantly lower than invasive measurements, with a low correlation (mean percentage error of 52%).

Why the study?

Traditional hemodynamic monitoring during TAVI relies on invasive methods, prompting evaluation of the reliability and feasibility of the non-invasive ClearSight Finger Cuff system.

Does non-invasive hemodynamic monitoring using the ClearSight Finger Cuff system provide reliable measurements compared to invasive monitoring in patients undergoing TAVI?

Population

50 patients undergoing elective TAVI at two tertiary hospitals

Comparison

Non-invasive ClearSight Finger Cuff monitoring vs traditional invasive hemodynamic monitoring

Design

Prospective observational study

Follow-up

30 days

Overview

Non-invasive finger cuff monitoring appears feasible during TAVI; leaves open whether it can reliably replace invasive methods in practice.

Structured PICO

Does non-invasive hemodynamic monitoring using the ClearSight Finger Cuff system provide reliable measurements compared to invasive monitoring in patients undergoing TAVI?

P
Population
50 patients with aortic valve stenosis undergoing elective TAVI, median age 82 years, 50% female, recruited from two tertiary hospitals.
I
Intervention
Non-invasive continuous hemodynamic monitoring using the ClearSight Finger Cuff system during TAVI procedures.
C
Comparator
Traditional invasive hemodynamic monitoring using arterial and pigtail catheters (with a subset undergoing right heart catheterization).
O
Outcome
Reliability and feasibility of non-invasive hemodynamic monitoring compared to traditional invasive hemodynamic monitoring (cardiac output, cardiac index, stroke volume, and blood pressure).surrogate

The ClearSight non-invasive hemodynamic monitoring system provides lower absolute values and correlates poorly with traditional invasive monitoring during TAVI procedures.
