Abstract

Purpose of Review

This review aims to provide a comprehensive overview of mavacamten in the management of obstructive hypertrophic cardiomyopathy (oHCM), from its molecular mechanism of action to clinical trial outcomes and real-world application. It explores the efficacy, safety, and practical considerations of mavacamten use, while highlighting evolving indications and future directions.

Recent Findings

Randomized trials have shown that mavacamten significantly reduces left ventricular outflow tract gradients, improves symptoms and exercise capacity, and induces structural reverse remodeling with a favorable safety profile. Real-world data confirm these benefits in broader patient populations. Pharmacogenetic variability, titration protocols, and cost-effectiveness analyses have further refined its clinical use.

Summary

Mavacamten represents a paradigm shift in oHCM treatment by targeting disease at its sarcomeric origin. Its integration into routine care is expanding, supported by real-world evidence. Ongoing studies will clarify its role in non-obstructive HCM, heart failure with preserved ejection fraction, pediatric populations, and early-stage disease.
