Marfan's syndrome: pre-pubertal aortic rupture with left coronary artery aneurysms and fistulas

Area of Science:

• Cardiovascular Medicine
• Genetics
• Pediatric Cardiology

Background:

• Marfan syndrome is a genetic disorder affecting connective tissue.
• Aortic dissection and rupture are common, severe complications in Marfan syndrome patients, typically occurring in adulthood.
• Early diagnosis and management are crucial for improving outcomes.

Observation:

• This report presents the first documented case of prepubertal left coronary sinus rupture.
• The rupture was associated with left coronary artery aneurysms and fistulous communication to the superior vena cava and right superior pulmonary vein.
• The patient presented with a continuous murmur, an unusual finding for this condition.

Findings:

• The case highlights an exceptionally early onset of severe aortic complications in Marfan syndrome.
• The complex fistulous communication presented unique diagnostic and therapeutic challenges.
• Continuous murmur indicated abnormal blood flow, aiding in diagnosis.

Implications:

• This case underscores the need for vigilant cardiovascular monitoring in prepubertal children with Marfan syndrome.
• It expands the understanding of the spectrum and potential severity of aortic pathologies in this population.
• Highlights the importance of considering rare presentations in pediatric cardiovascular emergencies.
