Insights
Transcatheter atrial septal defect (ASD) closure is safe and effective. Adverse outcomes were linked to male sex, being overweight, and stroke history, not age.
Area of Science:
- Cardiology
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Transcatheter atrial septal defect (ASD) closure is the standard treatment for secundum ASD.
- Long-term outcome data for transcatheter ASD closure are limited.
- Understanding adverse event prevalence is crucial for patient management.
Purpose of the Study:
- To determine the prevalence of adverse outcomes after transcatheter ASD closure.
- To evaluate the safety and efficacy of transcatheter ASD closure in a diverse patient population.
- To identify factors associated with adverse outcomes.
Main Methods:
- Retrospective cohort study.
- Inclusion of 277 patients undergoing transcatheter ASD closure between 2010 and 2021.
- Minimum 1-year follow-up with median of 37 months.
Main Results:
- Overall mortality was 1.8%, with no device-related deaths.
- Heart failure hospitalization occurred in 0.7% of patients.
- New-onset atrial fibrillation (2.7%) and pulmonary hypertension (0.6%) were key adverse outcomes. Male sex, overweight status, and prior stroke were associated with adverse events.
Conclusions:
- Transcatheter ASD closure is a safe and effective procedure.
- Age is not a barrier to successful ASD closure.
- Risk factors for adverse outcomes include male sex, overweight, and stroke history.
Background:
Transcatheter atrial septal defect (ASD) closure is the primary approach for treating ASD secundum; however, data on long-term outcomes remain limited. This study aimed to elucidate the prevalence of adverse outcomes following transcatheter ASD closure in a diverse population.
Methods:
This retrospective cohort study was conducted at the Songklanagarind Hospital and included patients who underwent transcatheter ASD closure between January 2010 and August 2021.
Results:
The study included 277 patients who completed follow-up for at least 1 year, with varying ages: <25 years (31%), 25-40 years (19%), 40-60 years (34%), and >60 years (16%). The median follow-up duration was 37 months (interquartile range: 20, 61). The overall mortality rate was 1.8%, and no deaths were attributed to device-related complications. Hospitalization due to heart failure occurred in 0.7% of the cases. Most patients improved or stabilized based on the New York Heart Association functional class. Adverse outcomes included new-onset atrial fibrillation (prevalence: 2.7%) and pulmonary hypertension (prevalence: 0.6%). The resolution of pulmonary hypertension varied among age groups, with 100% resolution in patients <25 years. Multivariate analysis identified male sex, overweight, and history of stroke to be significantly associated with adverse outcomes after transcatheter ASD closure.
Conclusion:
Transcatheter ASD closure was safe and effective, with age not being a limiting factor for success. Male sex, being overweight, and a history of stroke were associated with adverse outcomes. These findings contribute to our understanding of the long-term outcomes following ASD closure.
