Return-to-Play Post-Myocarditis Safety Calculator

Return-to-Play Post-Myocarditis: Explanation and Clinical Context This calculator applies current expert consensus for evaluating return-to-play (RTP) readiness after myocarditis. Clearance requires a minimum restriction period of 3–6 months, complete symptom resolution, normalized cardiac biomarkers (troponin, CRP), recovery of ventricular function (LVEF ≥ 50%), and absence of ventricular arrhythmias on resting or exercise ECG. CMR should demonstrate resolution of active inflammation; residual LGE may be acceptable with shared decision-making and close follow-up.

The logic follows major recommendations from the American College of Cardiology (ACC), American Heart Association (AHA), and European Society of Cardiology (ESC), not a numeric risk score. Output categories: Not Cleared, Conditional Clearance (residual LGE, no arrhythmia), and Cleared for Graded RTP (meets all criteria). Final decisions require clinical judgment, sport-specific risk assessment, and athlete preference.
