Insights
Color Doppler technology now quantifies myocardial strain and strain rates for assessing heart ventricle function in congenital heart disease. This review covers the technique
Area of Science:
- Cardiovascular imaging
- Echocardiography
- Myocardial mechanics
Background:

- To review clinical findings and applications in congenital heart disease.
Main Methods:
- Utilizes color Doppler methodology to analyze myocardial velocity profiles.
- Calculates regional myocardial strain rates and strain.
- Compares local myocardial velocity data for deformation analysis.
Main Results:
- Myocardial strain and strain rate calculations are feasible using color Doppler.
- These deformation data offer a novel approach to quantifying regional ventricular function.
- Clinical studies demonstrate the utility of this technique in congenital heart disease.
Conclusions:
- Color Doppler-based strain and strain rate analysis is a promising tool.
- It provides a new method for evaluating ventricular regional function in congenital heart disease.

Abstract:
Based on color Doppler methodology, regional myocardial strain rates and strain can now be calculated by comparing local myocardial velocity profiles. These deformation data sets may be an important new approach to quantifying regional function of the left or right ventricle in congenital heart disease. This review will give an introduction to the principles behind the technique and how data are acquired and processed. It will also discuss the findings of clinical studies based on this new technique.
