Hypertrophic Cardiomyopathy (HCM)

Hypertrophic cardiomyopathy (HCM) causes the walls of the left ventricle to become thicker than normal. This can cause a blockage to blood flow in some patient and is classified as obstructive HCM. This is the most common form of HCM where the septum between the ventricles can reduce the blood flow into the aorta. Nonobstructive HCM is where the heart muscle is thickened but does not block blood flow. The thickened walls stiffen and reduce the amount of blood the heart can pump. HCM is usually caused by an inherited genetic variant (familial hypertrophic cardiomyopathy) and can be detected with genetic testing and diagnosed with medical imaging. It is considered widely underdiagnosed. HCM can lead to heart failure and sudden cardiac arrest. Treatments include drug therapy, septal myectomy and alcohol septal ablation.

Hari Naidu D, FACC, FAHA, FSCAI, director of the Hypertrophic Cardiomyopathy (HCM) National Center of Excellence, and the cardiac catheterization labs at Westchester Medical Center, and HCM patient Lindsay Davis, who is a former Miss Ohio, co-authored a new children's book on HCM.

New hypertrophic cardiomyopathy guidelines highlight importance of exercise, new drug class

HCM is widely underdiagnosed, but the American College of Cardiology and American Heart Association hope their new guidelines can help cardiologists learn more about the potentially fatal condition and improve patient care. 

Purvi Parwani, MD, director of echocardiography, Loma Linda University Medical Center, explains the trend where heart failure imaging guidelines are driving a rising use of mixed multimodality imaging. #ASE #ASE2023

Multimodality imaging helps cardiologists manage heart failure patients—with an assist from AI

Purvi Parwani, MD, discussed the trend toward multimodality imaging for heart failure management. All modalities have their own weaknesses, she explained.

Why hypertrophic cardiomyopathy may be widely underdiagnosed

One expert believes the lack of standardization for how diagnostic imaging in conducted and reported has led to a major underdiagnosis of HCM.
