Left ventricular myocardial bands: MDCT and MR appearance

Area of Science:

• Cardiology
• Radiology
• Anatomy

Background:

• Left ventricular (LV) myocardial bands, also known as false tendons, are anatomical structures within the heart's main pumping chamber.
• These bands commonly appear during echocardiography and autopsy but are underrepresented in radiologic literature.

Observation:

• This article presents four cases where LV bands were visualized using advanced imaging modalities.
• Imaging techniques included echocardiography, multidetector computed tomography (MDCT), and magnetic resonance imaging (MRI).

Findings:

• The study details the imaging characteristics of LV bands across different modalities.
• It explores the embryologic development and anatomical variations of these myocardial structures.

Implications:

• The findings aim to increase radiologic awareness of LV bands, aiding in accurate diagnosis.
• Understanding the differential diagnosis and clinical significance of LV bands is crucial for patient management.
