Insights
Cardiac resynchronization therapy (CRT) improves heart function and remodeling. Imaging before CRT implantation helps predict patient outcomes by assessing reverse remodeling, crucial for heart failure management.
Area of Science:
- Cardiology
- Medical Imaging
- Heart Failure Management
Background:
- Cardiac resynchronization therapy (CRT) is an option for heart failure patients with systolic dysfunction unresponsive to medical therapy.
- The utility of pre-implantation noninvasive cardiac imaging for CRT remains debated.
- Cardiac reverse remodeling is linked to CRT outcomes.
Purpose of the Study:
- To review the acute and long-term benefits of CRT using imaging.
- To emphasize the role of cardiac reverse remodeling in CRT prognosis.
Main Methods:
- Review of existing literature on CRT and cardiac imaging.
- Analysis of studies assessing cardiac remodeling and patient outcomes post-CRT.
Main Results:
- Imaging can objectively assess cardiac reverse remodeling after CRT.
- Reverse remodeling is associated with improved long-term outcomes in CRT patients.
Conclusions:
- Noninvasive cardiac imaging is valuable for assessing CRT benefits.
- Evaluating cardiac reverse remodeling aids in predicting patient prognosis after CRT.
Abstract:
Cardiac resynchronization therapy (CRT) has become an alternative for patients with systolic dysfunction and persistence of heart failure symptoms despite optimal medical therapy. The role of noninvasive cardiac imaging before device implantation still remains controversial, but they are essential to provide an objective evidence of reverse remodeling of the heart which is, in turn, also related to the outcome of patients treated with CRT. The objective of this review is to highlight the acute and long-term CRT benefits as assessed by imaging, with special focus in cardiac reverse remodeling and its impact on prognosis.
