Multimodality imaging of hypertrophic cardiomyopathy

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Hypertrophic cardiomyopathy (HCM) is a complex cardiac condition requiring precise diagnosis and management.
• Accurate assessment of HCM is crucial for patient outcomes and risk stratification.

Purpose of the Study:

• To highlight the indispensable role of multimodality imaging in the comprehensive care of patients with hypertrophic cardiomyopathy.
• To delineate the specific contributions of different imaging modalities in diagnosing and managing HCM.

Main Methods:

• Utilizing transthoracic echocardiogram (TTE) as the primary diagnostic tool for identifying HCM morphology and obstruction.
• Employing cardiac magnetic resonance imaging (CMR) for adjudicating equivocal cases and assessing sudden cardiac death risk factors.
• Leveraging TTE and transesophageal echocardiogram (TEE) to guide interventional procedures like alcohol septal ablation and surgical myectomy.

Main Results:

• TTE effectively identifies key HCM features including left ventricular outflow obstruction, midcavitary obstruction, and systolic anterior motion.
• CMR provides crucial information for differential diagnosis and risk stratification in HCM patients.
• Echocardiography (TTE/TEE) is instrumental in guiding both procedural interventions and medical management by monitoring hemodynamic parameters like peak gradients.

Conclusions:

• Multimodality imaging, encompassing TTE and CMR, is fundamental for the complete diagnostic and therapeutic journey of hypertrophic cardiomyopathy patients.
• The integrated use of various imaging techniques ensures optimal patient management, from initial diagnosis through long-term follow-up and intervention guidance.
