Abstract Background Implantation of implantable cardioverter defibrillator (ICD) is a Class IIb indication in patients with Cardiac Sarcoid and with LVEF 36%-49% despite immunosuppression and optimal heart failure therapy. Purpose This systematic review and meta-analysis aimed to provide an estimate on the incidence of ventricular arrhythmias and risk of sudden cardiac death (SCD) in patients with CS. Methods The terms “Cardiac Sarcoidosis*” AND “Implantable Cardioverter Defibrillator” AND “Sudden Cardiac Death” were searched on PubMed, EMBASE, and Scopus on 21st of September 2018 yielding 759 articles. After exclusions, 12 studies met inclusion criteria. Results The 12 studies consisted of 612 patients with CS of which 534 had ICD implanted for primary or secondary prevention. Assuming appropriate device therapy as a surrogate for SCD, the annual incidence of appropriate ICD therapies and SCD combined was 6.3% (95% CI; 3.5%-9.1%) in primary prevention cohorts, 11.6% (95% CI; 7.8%-15.3%) in secondary prevention cohorts, and 8.7% (95% CI; 6.0%-11.5%) in both cohorts. The mean left ventricular ejection fraction (LVEF) was pooled as 59±7 (n=155) in primary prevention cohorts and 48±15 (n=48) in secondary prevention cohorts. However, the LVEF was 35±13 (n=28) in those with appropriate ICD therapy, and 49±16 (n=47) in those with ICDs without therapy. Incidence of SCD in Combined Cohorts Conclusion The incidence of ventricular arrhythmias and SCD is high not only secondary but also in primary prevention cohorts of CS. This data supports the role of implanting ICDs for primary prevention in patients with CS with mild to moderate reduction in LVEF. Acknowledgement/Funding None

Ventricular Lead

Dilated cardiomyopathy (DCM) is a disease characterised as left ventricular (LV) or biventricular dilatation with impaired systolic function. Regardless of underlying cause patients with DCM have a propensity to ventricular arrhythmias and sudden cardiac death. Implantable Cardioverter Defibrillator (ICD) implantation for these patients results in significant reduction of sudden cardiac death [1-3]. ICD devices may be limited by right ventricle (RV) sensing dysfunction with low RV sensing amplitude. We present a clinical case of patient with DCM, implanted ICD and low R wave sensing on RV lead.

AbstractImplantable cardioverter-defibrillators effectively reduce the rate of sudden cardiac death in children. Significant efforts have been made to better characterise the indications for their placement, and over the past two decades there has been a shift in their use from secondary to primary prevention. Primary prevention includes placement in patients thought to be at high risk of sudden cardiac death before the patient experiences any event. Secondary prevention includes placement after a high-risk event including sustained ventricular tachycardia or resuscitated cardiac arrest. Although liberal device implantation may be appealing even in patients having marginal indications, studies have shown high rates of adverse effects including inappropriate device discharges and the need for re-intervention because of hardware malfunction. The indications for placement of an implantable cardioverter-defibrillator, whether for primary or secondary prevention of sudden cardiac death, vary based on cardiac pathology. This review will assist the provider in understanding the risks and benefits of device implantation in order to enhance the shared decision-making capacity of patients, families, and providers.
