Key result
Simultaneous implantation of cardiac contractility modulation and a subcutaneous defibrillator successfully improved clinical symptoms in a 51-year-old man with advanced heart failure (LVEF 33%).
Why the study?
To report the feasibility of simultaneous implantation of cardiac contractility modulation and a subcutaneous implantable cardioverter-defibrillator in advanced heart failure.
Can simultaneous implantation of cardiac contractility modulation (CCM) and subcutaneous implantable cardioverter-defibrillator (S-ICD) improve clinical symptoms in patients with advanced heart failure?

Can simultaneous implantation of cardiac contractility modulation (CCM) and subcutaneous implantable cardioverter-defibrillator (S-ICD) improve clinical symptoms in patients with advanced heart failure?
Answers are grounded in this paper and cite their sources.
Simultaneous implantation of CCM and S-ICD is feasible and may improve symptoms in patients with advanced heart failure and reduced ejection fraction.
BACKGROUNDS: Two 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 REPORT: We 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. CONCLUSION: Our 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.
