Why the study?

To examine the agreement between 2D and 3D speckle-tracking echocardiography measurement of global longitudinal strain in patients with a normal left ventricle, reduced ejection fraction, and cardiac pacing.

Does 3D speckle-tracking echocardiography agree with 2D speckle-tracking echocardiography for measuring global longitudinal strain in patients with normal and abnormal left ventricular function?

Population

90 consecutive patients with valid 2D and 3D loops for speckle-tracking strain analysis

Comparison

2D vs 3D speckle-tracking echocardiography GLS measurement

Design

Observational agreement study

Overview

2D-3D GLS agreement is weaker with pacing or LVEF <35%; leaves open interchangeability in these subgroups.

Structured PICO

Does 3D speckle-tracking echocardiography agree with 2D speckle-tracking echocardiography for measuring global longitudinal strain in patients with normal and abnormal left ventricular function?

P
Population
90 consecutive patients (59% males; average age: 73.2 ± 11.2 years) with valid 2D and 3D loops for speckle-tracking strain analysis, including patients with normal left ventricle, reduced ejection fraction, and cardiac pacing.
I
Intervention
Three-dimensional (3D) speckle-tracking echocardiography (STE) measurement of global longitudinal strain (GLS)
C
Comparator
Two-dimensional (2D) speckle-tracking echocardiography (STE) measurement of global longitudinal strain (GLS)
O
Outcome
Agreement and correlation between 2D and 3D GLS measurements globally and per segmentsurrogate

2D and 3D speckle-tracking echocardiography measurements of global longitudinal strain are closely associated globally, but correlation is reduced when analyzed per segment, in patients with right ventricular pacing, or in those with reduced left ventricular ejection fraction.
