Cardiac Imaging in Athlete's Heart: The Role of the Radiologist

Area of Science:

• Cardiology
• Radiology
• Sports Medicine

Background:

• Athlete's heart (AH) presents as cardiac modifications from sustained athletic training.
• Structural myocardial changes in athletes can resemble or mask underlying cardiomyopathies.
• Distinguishing AH from cardiomyopathy is crucial for preventing sudden cardiac death.

Purpose of the Study:

• To review cardiac magnetic resonance (CMR) and cardiac computed tomography (CCT) techniques for evaluating cardiac morphology, function, and tissue characterization.
• To analyze the imaging features of Athlete's Heart (AH).
• To highlight key imaging differences between AH and various cardiomyopathies for differential diagnosis.

Main Methods:

• Review of current literature on advanced cardiac imaging modalities.
• Focus on Cardiac Magnetic Resonance (CMR) and Cardiac Computed Tomography (CCT) applications.
• Analysis of imaging findings specific to Athlete's Heart and cardiomyopathies.

Main Results:

• Improved imaging technologies (CMR, CCT) enhance the ability to differentiate AH from cardiomyopathies.
• Radiologists play a key role in identifying adaptive changes in AH versus pathological findings in cardiomyopathies.
• Specific imaging features of AH and cardiomyopathies are detailed for diagnostic guidance.

Conclusions:

• Advanced cardiac imaging, particularly CMR and CCT, is pivotal in the differential diagnosis of Athlete's Heart and cardiomyopathies.
• Accurate differentiation is essential for risk stratification and preventing adverse cardiac events in athletes.
• Radiological expertise in cardiac imaging is critical for distinguishing physiological adaptations from pathological conditions.
