Follow-up will be performed at 2 weeks post-implant for incision check and device interrogation as is standard of care. In addition, routine device and clinical follow-up will be scheduled at 1, 3, 6, and 12 months. Electrocardiography (ECG) will be performed pre-implant, prior to hospital discharge, at 3 months, 6 months, and 12 months. Echocardiography will be performed pre-implant and 6 months to evaluate for change in LVEF, chamber dimension, and wall motion with strain imaging as is standard of care in the treatment of patients with advanced heart failure. NYHA functional class and quality of life (utilizing the Kansas City Cardiomyopathy Questionnaire) will be assessed pre-implant and at 6 months.
