Transthyretin Amyloid Cardiomyopathy: Current Diagnostic Approach and Risk Stratification with Multimodality Imaging.

Area of Science:

• Cardiology
• Medical Imaging
• Biomarkers

Background:

• Amyloidosis is an infiltrative disease potentially causing cardiomyopathy.
• Transthyretin amyloid cardiomyopathy requires timely and accurate diagnosis for effective treatment.

Purpose of the Study:

• To review the role of multimodality cardiac imaging in transthyretin amyloid cardiomyopathy.
• To discuss imaging's application from diagnosis to prognosis and treatment response.

Main Methods:

• Review of multimodality imaging techniques including ECG, echocardiography, cardiac MRI, and bone scintigraphy.
• Analysis of imaging biomarkers for disease assessment and risk stratification.

Main Results:

• Multimodality imaging raises suspicion and bone scintigraphy aids diagnosis, often obviating biopsy.
• Cardiac imaging biomarkers provide prognostic insights at diagnosis and after treatment.

Conclusions:

• Multimodality cardiac imaging is vital for managing transthyretin amyloid cardiomyopathy.
• Imaging facilitates personalized patient care by tracking disease evolution and treatment efficacy.
