The different faces of echocardiographic left ventricular hypertrophy: clues to the etiology

Area of Science:

• Cardiology
• Cardiac Imaging
• Diagnostic Medicine

Background:

• Left ventricular hypertrophy (LVH) is a common cardiac response to diverse stimuli, including exercise and various diseases.
• LVH is not uniform; its morphologic and functional characteristics vary based on the underlying cause.
• Accurate characterization of LVH is crucial for timely diagnosis of associated conditions.

Purpose of the Study:

• To systematically review echocardiographic patterns associated with different types of cardiac hypertrophy.
• To guide clinicians in interpreting echocardiographic findings for early diagnosis of underlying cardiac conditions.
• To address the lack of comprehensive guidance on approaching LVH in clinical practice.

Main Methods:

• Systematic review of established and advanced echocardiographic imaging modalities.
• Analysis of typical echocardiographic patterns for important types of cardiac hypertrophy.
• Focus on morphologic and functional characteristics relevant to diagnosis.

Main Results:

• Echocardiography reveals distinct patterns of LVH depending on the underlying pathologic mechanism.
• Specific imaging features correlate with different etiologies of cardiac hypertrophy.
• The review provides a framework for interpreting these patterns.

Conclusions:

• Echocardiography is the clinical reference standard for assessing LVH.
• Recognizing specific echocardiographic patterns of LVH facilitates the diagnosis of underlying cardiac and systemic diseases.
• This systematic approach enhances diagnostic accuracy and timely intervention.
