Taut and click: an unusual left ventricular false tendon

Area of Science:

• Pediatric Cardiology
• Cardiac Anatomy

Background:

• Persistent systolic ejection clicks in children can indicate underlying cardiac abnormalities.
• The precise etiology of such clicks is not always clear, necessitating further investigation into cardiac structures.

Observation:

• An asymptomatic child presented with a persistent systolic ejection click.
• Echocardiographic and anatomical examination revealed an unusual left ventricular false tendon.

Findings:

• A previously undescribed left ventricular false tendon was identified.
• This anomalous structure was observed to be attached to the aortic valve.

Implications:

• The identified false tendon may be the novel cause of the observed systolic ejection click.
• This finding expands the understanding of cardiac anatomical variations and their clinical manifestations.
• Highlights the importance of detailed anatomical assessment in diagnosing cardiac sounds.
