A young woman experienced hypertension and graft calcification 18 years after surgery for coarctation of the aorta. Trans-catheter interventions for graft occlusion present significant challenges.

Area of Science:

  • Cardiovascular Surgery
  • Interventional Cardiology
  • Vascular Medicine

Background:

  • Coarctation of the aorta (CoA) repair often involves grafts.
  • Long-term complications of aortic grafts can include stenosis and calcification.
  • Bicuspid aortic valve is a common comorbidity associated with CoA.

Observation:

  • A patient with a history of left subclavian artery to descending aorta jump graft for post-subclavian coarctation presented 18 years later.
  • The patient exhibited significant hypertension and a 40 mmHg gradient across a calcified Dacron graft.
  • Moderate aortic regurgitation secondary to a bicuspid aortic valve was also noted.

Findings:

  • Graft calcification and stenosis led to a substantial pressure gradient.
  • The presence of an occluded Dacron graft raises concerns for trans-catheter interventions.

  • Aortic regurgitation adds complexity to the management of this patient.

    • Implications:

    • Careful consideration of management strategies is crucial for long-term graft patency and patient outcomes.
    • Trans-catheter options may be limited or carry increased risks in cases of occluded Dacron grafts.
    • This case highlights the importance of long-term surveillance for patients with aortic reconstruction.
