Pulmonary valve regurgitation after initial repair was successfully treated with autologous pericardium valve plasty in a pediatric patient. This procedure effectively addressed cusp damage and improved valve function.
Area of Science:
- Cardiology
- Pediatric Surgery
- Cardiovascular Surgery
Background:
- A 6-year-old boy with a history of aortic coarctation and ventricular septal defect required reoperation due to progressive pulmonary valve regurgitation.
- The initial surgical correction at 18 days old involved an incision through the pulmonary valve, potentially leading to cusp damage.
