BackgroundsTwo technologies, cardiac contractility modulation (CCM) and subcutaneous implantable cardioverter‐defibrillator (S‐ICD), can be successfully combined and applied to patients with advanced heart failure (HF) with reduced left ventricular ejection fraction (LVEF).Case ReportWe reported a case of a 51‐year‐old man with reduced ejection fraction (LVEF = 33%) and a narrow QRS complex who first underwent simultaneous implantation of CCM and S‐ICD.ConclusionOur case report aimed to reveal that the simultaneous implantation of CCM and S‐ICD could be successfully used in patients with advanced HF, which could significantly improve the clinical symptoms of such patients during one surgery.
