Insights
This case study highlights the longest reported survivor of a Brock procedure for critical pulmonary valve stenosis, demonstrating long-term positive outcomes 63 years post-surgery. The patient successfully managed recurrent stenosis and a large pulmonary artery aneurysm.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Medical Case Reports
Background:
- The patient, diagnosed with critical pulmonary valve stenosis in infancy, underwent a palliative Brock procedure in 1957.
- Subsequent surgical interventions included repair of pulmonary stenosis and an atrial septal defect (ASD) at age 6, and repair of paradoxical embolization due to a residual ASD at age 17.
Observation:
- The patient presented 54 years after the initial Brock procedure with recurrent pulmonary stenosis.
- A symptomatic 6.2-cm pulmonary artery aneurysm was identified and subsequently repaired using a 23-mm aortic homograft.
Findings:
- This case represents the longest documented postoperative survival following a Brock procedure.
- The patient remains in good health 63 years after her initial cardiac surgery.
Implications:
- This report underscores the potential for exceptional long-term survival and quality of life in patients undergoing early palliative cardiac procedures for congenital heart defects.
- It highlights the importance of lifelong surveillance for patients with complex congenital heart disease, even decades after initial interventions.
- The successful management of late complications, such as pulmonary artery aneurysm, demonstrates the feasibility of advanced surgical repairs in long-term survivors.
Abstract:
An infant with critical pulmonary valve stenosis underwent a Brock procedure in 1957 with subsequent repair of pulmonary stenosis and an atrial septal defect at age 6. At age 17 she underwent repair for paradoxical embolization secondary to a residual atrial septal defect. She presented 54 years later with recurrent pulmonary stenosis and a symptomatic 6.2-cm pulmonary artery aneurysm repaired with a 23-mm aortic homograft. This patient is the longest reported postoperative survivor after a Brock procedure. She continues to do well 63 years after her initial surgery.
