[Complete atrioventricular block in a youth with mitral prolapse]

Area of Science:

• Cardiology
• Electrophysiology
• Valvular Heart Disease

Background:

• Mitral valve prolapse (MVP) is a common valvular condition.
• Atrioventricular (A-V) block is a disruption of cardiac electrical conduction.
• The association between MVP and A-V block is not well-established, particularly in young patients.

Observation:

• A 16-year-old patient presented with recurrent episodes of mitral valve prolapse (MVP).
• The patient was diagnosed with complete atrioventricular (A-V) block.
• Further investigations confirmed the presence of a prolapse of the rear flap of the mitral valve.

Findings:

• A direct correlation between mitral valve prolapse and complete atrioventricular block was observed in this young patient.
• Literature review suggests potential pathogenic links between these two conditions.
• Rheumatic etiology is hypothesized as a common underlying cause for both MVP and conduction abnormalities.

Implications:

• This case highlights a potential, albeit rare, association between mitral valve prolapse and atrioventricular block in adolescents.
• Further research is warranted to elucidate the mechanisms connecting valvular abnormalities and cardiac conduction defects.
• Early recognition and investigation of conduction abnormalities in patients with MVP may be crucial for timely management.
