Recently, mavacamten, a cardiac myosin inhibitor, has demonstrated improvement in quantitative measures of obstruction and symptom relief to such a degree that patients were able to defer invasive management of the disease.This review focuses on the pharmacology of mavacamten, its clinical trial data and guidance on how to incorporate this drug into clinical practice.Furthermore, it discusses emerging therapies currently being investigated for HCM.Keywords: hypertrophic cardiomyopathy, mavacamten, septal reduction therapy, EXPLORER HCM, VALOR HCM.
