Use of cardiac contractility modulation combined with left bundle branch pacing CRT‐P in a female with a 22‐year history of non‐ischemic dilated cardiomyopathy: A case report.

Cardiac contractility modulation (CCM) is a novel device‐based therapy used to treat patients with heart failure with reduced ejection fraction (HFrEF). In both randomized clinical trials and real‐life studies, CCM has been shown to improve exercise tolerance and quality of life, reverse left ventricular remodeling, and reduce hospitalization in patients with HFrEF. In this case report, we describe for the first time the use of CCM combined with left bundle branch pacing (LBBP) cardiac resynchronization therapy pacemaker (CRT‐P) implantation therapy in a female with a 22‐year history of non‐ischemic dilated cardiomyopathy. With the optimal medical therapy and cardiac resynchronization therapy (CRT) strategies, the patient's quality of life initially recovered to some extent, but began to deteriorate in the past year. Additionally, heart transplantation was not considered due to economic reasons and late stage systolic heart failure. This is the first case of CCM implantation in Fujian Province and the first report of a combined CCM and left bundle branch pacing CRT‐P implantation strategy in a patient with non‐ischemic etiology dilated cardiomyopathy in China.
