Maron Model (HCM SCD Prediction) Calculator

Maron Model (HCM SCD Prediction): Explanation and Clinical Context The Maron Model is a validated risk prediction tool for estimating the 5-year risk of sudden cardiac death (SCD) in patients with hypertrophic cardiomyopathy (HCM). It incorporates easily obtainable clinical and echocardiographic variables, including maximal left ventricular wall thickness, left atrial diameter, left ventricular outflow tract gradient, family history of SCD, unexplained syncope, and presence of non-sustained ventricular tachycardia (NSVT) on Holter monitoring. The model uses a logistic regression-based linear predictor to calculate the estimated risk of SCD over a 5-year period.

Clinicians can use this tool for risk stratification and to guide decisions regarding primary prevention ICD implantation.
