Programmed ventricular stimulation in arrhyhtmogenic myocarditis: Foraging into the unknown!

The authors discuss a study on the utility of programmed ventricular stimulation in patients with active versus prior arrhythmic myocarditis. Highlights include the use of endomyocardial biopsy as a risk-stratification tool, pathophysiology of ventricular arrhythmia in myocarditis, and the lack of T2-mapping techniques with cardiovascular magnetic resonance and the timing of electrophysiologic imaging before biopsy results.
