Insights
Cardiac resynchronization therapy (CRT) offers hope for heart failure (HF) patients. This review explores CRT
Area of Science:
- Cardiology
- Adult Congenital Heart Disease
Background:
- Adult congenital heart disease (CHD) survival is increasing.
- These patients may develop heart failure (HF) and ventricular dysfunction.
- Cardiac resynchronization therapy (CRT) is an option for HF management.
Purpose of the Study:
- To review unique features of CRT in adult CHD patients.
- To examine current data on CRT utilization in this population.
- To discuss limitations and technical considerations for CRT in CHD.
Main Methods:
- Literature review of existing data on CRT in adult CHD.
- Analysis of utilization, benefits, and data availability.
- Review of coronary sinus anatomy and LV lead placement in CHD.
Main Results:
- Limited data exists on CRT utilization and benefits in adult CHD.
- Specific anatomical challenges exist for LV lead placement.
- Further research is needed to optimize CRT in this population.
Conclusions:
- CRT may benefit select adult CHD patients with HF.
- Careful patient selection and technical considerations are crucial.
- More research is required to establish optimal CRT strategies for CHD.
Abstract:
Cardiac resynchronization therapy (CRT) is a commonly used procedure to help patients with drug refractory heart failure (HF) symptoms. More patients with congenital heart disease (CHD) survive to adulthood with the improvements that have occurred as a result of surgical and medical care of these patients. However, patients with CHD may develop ventricular dysfunction and HF and thus be considered for CRT. In this review, we discuss the unique features of CRT in the adult CHD population. We examine the existing data on utilization of CRT in patients with HF and CHD and specifically discuss the limitations in terms of benefit as well as data availability. Finally, we review the specific coronary sinus anatomy and technical considerations for placing a left ventricular lead in patients with CHD.
