Right ventricular mechanics using a novel comprehensive three-view echocardiographic strain analysis in a normal...

Area of Science:

• Cardiology
• Echocardiography
• Cardiac Imaging

Background:

• Quantitative right ventricular (RV) strain analysis is valuable for RV failure but lacks standardization.
• An 18-segment RV strain analysis using three apical views was developed.

Purpose of the Study:

• To determine the feasibility, normal values, and reproducibility of a novel 18-segment RV strain analysis.
• To assess the method's utility in identifying RV disease.

Main Methods:

• Echocardiography with 2D speckle-tracking strain analysis in 40 healthy adults.
• Utilized EchoPAC software and three standardized RV apical views.
• Included 11 patients with RV disease as a pilot group.

Main Results:

• Feasibility of RV strain analysis was high (97%).
• Normal RV global peak systolic strain was -23 ± 2%.
• The method detected RV disease missed by standard views, showing distinct strain patterns.

Conclusions:

• The 18-segment RV strain analysis is feasible and provides reproducible measures in normal adults.
• This technique shows potential for detailed evaluation of abnormal RV populations.
