Infantile midaortic syndrome with aortic occlusion

Area of Science:

• Pediatric Cardiology
• Vascular Surgery

Background:

• Mid aortic syndrome (MAS) is a rare congenital condition characterized by narrowing of the abdominal aorta, often leading to severe hypertension.
• Early diagnosis and intervention are crucial for managing MAS, particularly in infants presenting with critical symptoms like heart failure.

Observation:

• A case of complete abdominal aortic occlusion presenting in an infant at four months of age with severe hypertension and heart failure.
• Initial assessment deemed the condition too severe for surgical intervention, with palliative care considered.

Findings:

• Successful angioplasty was performed at five and a half months, followed by three additional procedures.
• The patient required antihypertensive agents but maintained normal renal function.
• At six years old, the child exhibits normal growth, development, and excellent quality of life with controlled blood pressure.

Implications:

• This case highlights the efficacy of combining medical management with endovascular procedures like angioplasty for severe infantile MAS.
• Aggressive interventional treatment can lead to favorable long-term outcomes, including normal development and quality of life, even in complex cases.
• It suggests that even seemingly inoperable cases of MAS may benefit from a multidisciplinary approach involving interventional cardiology and medical therapy.
