ICD indications

Class I

• Patients with left ventricular dysfunction due to prior myocardial infarction who are at least 40 days post MI with LVEF <30-40%, are NHA class II or III and are receiving chronic optimal medical therapy and with life expectancy > 1 year. IA
• LV dysfunction due to prior MI, presenting with hemodynamically unstable sustained VT. IA
• Patients with non-ischemic dilated cardiomyopathy (NI DCM) with LV dysfunction who have sustained VT or VF. IA
• NI DCM LVEF<30-35%. NYHA II-III. Chronic medical therapy. Life expectancy > 1 year. IB
• Hypertrophic cardiomyopathy with sustained VT or VF. IB

Class IIa

• LV dysfunction due to prior MI, at least 40 days post MI, LVEF < 30-35%, NYHA I, on chronic medical therapy, life expectancy >1y. IIaB
• Recurrent VT in post MI patient with normal or near normal LVEF on chronic medical therapy, life expectancy > 1y. IIaC
• In patients with life threatening arrhythmias who are not in the acute phase of myocarditis, on chronic medical therapy, life expectancy >1y. IIaC
• Unexplained syncope, significant LV dysfunction, non-ischemic DCM. Optimal medical therapy, LE>1y. IIaC
• Sustained VT with (near) normal LV function and non-ischemic DCM. Optimal medical therapy, LE>1y. IIaC
• Hypertrophic cardiomyopathy with one or more major risk factors. Optimal medical therapy, LE>1y. IIaC

Class IIb

• ICD implantation is not recommended during the acute phase of myocarditis
