Hypothesis
What are the changes in right ventricular size and function after percutaneous closure of secundum atrial septal defects?
Conclusion
Most patients experience significant improvement in right ventricular dimensions within 24 hours after closure, with further gradual recovery observed over time.
Supporting Evidence
- RV dimensions improved significantly within 24 hours after closure.
- End-diastolic RV basal diameter decreased from 4.5 cm to 3.9 cm.
- NYHA functional class improved from 1.5 to 1.0 at follow-up.
Takeaway
When doctors fix a hole in the heart, the heart's right side gets smaller and works better really quickly, and it keeps getting better over time.
Methodology
This was a retrospective cohort study analyzing echocardiographic data from patients before and after percutaneous ASD closure.
Potential Biases
Potential bias due to the retrospective nature and missing data from many patients.
Limitations
The study faced limitations due to missing echocardiographic data and the retrospective design, which may introduce selection bias.
Participant Demographics
Median age of participants was 46 years, with a male to female ratio of 2:3.
