HCM Spectrum Disorders
At the International Summit on Hypertrophic Cardiomyopathy held in Boston October 2017 it was agreed to use a new term for those conditions once refered to as HCM phenocopies. There are a family of disorders that have HCM as a feature of the underlying condition. While the majority of these conditions treat the heart much as an HCM heart is treated, there are some important differences in treatment and management of HCM spectrum disorders. This term "spectrum disorder" refers specifically to the presents of HCM without sarcomere mutations and with other features that may include abnormalities that occur in organs or systems outside of the heart.
The subsections of this page will address the various disorders.
