Heart transplantation following myocardial infarction due to Takayasu's arteritis

Area of Science:

• Cardiology
• Vascular Surgery
• Rheumatology

Background:

• Takayasu's arteritis is a rare, large-vessel vasculitis.
• It can affect the aorta and its branches, including coronary arteries.
• Complications can lead to severe cardiac dysfunction.

Observation:

• A 14-year-old female presented with cardiogenic shock.
• Coronary artery compression, specifically the left main coronary artery, was identified as the cause.
• Ascending aortitis was also present, necessitating extensive surgical intervention.

Findings:

• The patient required emergent cardiac transplantation.
• A hemi-arch replacement was performed concurrently with the transplant.
• This represents the first reported case of cardiac transplantation for Takayasu's arteritis.

Implications:

• Cardiac transplantation is a viable option for managing life-threatening cardiac complications of Takayasu's arteritis.
• Early diagnosis and intervention are crucial in pediatric cases.
• This case expands treatment options for severe Takayasu's arteritis.
