Insights
Cardiac resynchronization therapy (CRT) shows promise for congenital heart disease (CHD) patients with heart failure. Echocardiography can identify mechanical dyssynchrony to guide CRT selection in this heterogeneous population.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Biomedical Engineering
Background:
- Congenital heart disease (CHD) patient numbers are rising, with heart failure being a leading cause of mortality.
- Cardiac resynchronization therapy (CRT) offers potential benefits for heart failure in CHD and pediatric populations.
- The heterogeneity of CHD anatomical substrates complicates CRT efficacy.
Purpose of the Study:
- To review the role of CRT in pediatric and CHD patients experiencing heart failure.
- To evaluate current CRT inclusion criteria and outcomes across diverse anatomical subgroups.
- To discuss echocardiographic assessment of mechanical dyssynchrony for predicting CRT response.
Main Methods:
- Review of existing literature on CRT in CHD and pediatric heart failure.
- Analysis of current CRT inclusion criteria and outcomes in various CHD anatomical subtypes.
- Comprehensive discussion of echocardiographic methods for assessing mechanical dyssynchrony.
Main Results:
- CRT is a potential therapeutic option for heart failure in CHD and pediatric patients.
- Patient heterogeneity and specific anatomical features significantly impact CRT effectiveness.
- Echocardiography, particularly novel tools, aids in assessing cardiac dyssynchrony for CRT candidate selection.
Conclusions:
- CRT may improve clinical outcomes for pediatric and CHD patients with heart failure.
- Tailoring CRT based on individual anatomy and dyssynchrony assessment is crucial for success.
- Echocardiography plays a vital role in optimizing CRT application in this population.
Abstract:
The number of patients with congenital heart disease (CHD) has significantly increased over the last decades. The CHD population has a high prevalence of heart failure during late follow-up and this is a major cause of mortality. Cardiac resynchronization therapy (CRT) may be a promising therapy to improve the clinical outcome of CHD and paediatric patients with heart failure. However, the CHD and paediatric population is a highly heterogeneous group with different anatomical substrates that may influence the effects of CRT. Echocardiography is the mainstay imaging modality to evaluate CHD and paediatric patients with heart failure and novel echocardiographic tools permit a comprehensive assessment of cardiac dyssynchrony that may help selecting candidates for CRT. This article reviews the role of CRT in the CHD and paediatric population with heart failure. The current inclusion criteria for CRT as well as the outcomes of different anatomical subgroups are evaluated. Finally, echocardiographic assessment of mechanical dyssynchrony in the CHD and paediatric population and its role in predicting response to CRT is comprehensively discussed.
