TABLE 3.

Primary and secondary ICD prevention indications according to the clinical scenario of presentation.

Primary prevention	Acute phase of myocarditis	Chronic phase of myocarditis
	– Consider WCD as a bridge during therapy optimization (∞) – Consider earlier ICD implantation (∞)	– ICD implantation according to International HF Guidelines (*)
Secondary Prevention	MAE in the acute phase of myocarditis	MAE in the chronic phase of myocarditis
	– ICD implantation suggested prior to discharge (∞) – WCD for three months not suggested (∞)	– ICD implantation mandatory by International Guidelines (*)

ICD, implantable cardiac defibrillator; WCD, wearable cardiac defibrillator; HF, heart failure, MAE, major arrhythmic ventricular events. *, corroborated by International Guideline indications; ∞, suggest by our group of work, deserve to be addressed in future clinical research.
