FACT-CRT: Factors Associated with Response to Cardiac Resynchronization Therapy in Heart Failure Patients with Non-LBBB ECG Pattern
Brief description of study
This research study seeks to validate how echocardiogram (echo) data predicts response to cardiac resynchronization therapy (CRT) provided by a CRT device with a defibrillator (CRT-D) in individuals without the heart arrhythmia abnormality left bundle branch block (LBBB). It also aims to identify new variables recorded from electrocardiograms (ECG) or echocardiography to improve use of CRT in patients with heart failure.
Detailed description of study
Consented participants must first complete a 20-minute ECG recording, and the study team will record their echo data before CRT-D implant. The echo data can be from any echo done within 1 year prior to CRT-D implant.
After enrollment, the study team collects data about the procedure and the implanted device. They will reach out to participants via phone every 6 months to collect medical information and data from their device. Participation in this study lasts for about 48 months.
