Summary
Surgery for atrial septal defects type II in adults is effective with low mortality. However, some patients not operated on showed health deterioration, questioning strict surgical criteria for small shunts.
Area of Science:
- Cardiology
- Cardiac Surgery
- Adult Congenital Heart Disease
Context:
- Surgical indication criteria for atrial septal defects type II (ASD II) in adults lack uniformity.
- A retrospective study analyzed outcomes of operated and non-operated adult ASD II patients.
Purpose:
- To evaluate the outcomes of surgical intervention for adult ASD II.
- To reassess the established surgical indication criteria based on long-term follow-up data.
Summary:
- 150 adult patients with ASD II underwent surgery between 1978-1987, with a 0.7% operative mortality and satisfactory outcomes.
- 16 non-operated ASD II patients with minor hemodynamic impact were followed; four showed health deterioration, suggesting potential under-treatment.
- The study questions the strict 1.5:1 left-to-right shunt ratio as the sole criterion for surgery in adults.
Impact:
- Findings suggest that surgical intervention for adult ASD II may be indicated even with smaller shunts.
- Highlights the need for revised, individualized indication criteria for adult ASD II surgery.
- Contributes to optimizing treatment strategies for adult congenital heart disease.
