Multimodality Imaging in Cardiomyopathies with Hypertrophic Phenotypes

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Left ventricular hypertrophy (LVH) is a cardiac condition characterized by increased LV wall thickness.
• Hypertrophic cardiomyopathy (HCM) is a specific form of LVH not caused by abnormal loading conditions.
• Accurate diagnosis and risk stratification are crucial for managing HCM patients.

Purpose of the Study:

• To review the current applications of multimodality imaging in adult patients with HCM.
• To highlight the role of various imaging techniques in HCM diagnosis and management.
• To emphasize the importance of identifying specific etiologies of HCM.

Main Methods:

• Review of current literature on multimodality imaging in HCM.
• Discussion of key imaging modalities including echocardiography, cardiac MRI, CT, and nuclear imaging.
• Analysis of imaging's contribution to diagnosis, risk stratification, and treatment guidance.

Main Results:

• Multimodality imaging provides comprehensive morphologic and functional data for LVH and HCM.
• Different imaging techniques offer complementary information for diagnosis and management.
• Imaging is essential for identifying specific causes like Fabry disease and cardiac amyloidosis.

Conclusions:

• Multimodality imaging is a cornerstone in the evaluation of adult patients with HCM.
• It facilitates accurate diagnosis, risk stratification for sudden cardiac death, and personalized treatment strategies.
• Identifying underlying causes through imaging enables targeted therapies for specific HCM subtypes.
