Hypothesis
What are the risk factors for vertical vein persistence after total anomalous pulmonary vein return surgery?
Conclusion
An LA diameter Z score lower than -4 is a major risk factor for vertical vein persistence, and percutaneous embolization is a safe and effective procedure.
Supporting Evidence
- The early postoperative mortality rate was 17.5%, significantly higher in patients with combined congenital heart disease.
- Four patients underwent vertical vein embolization, achieving complete occlusion with AVP2.
- An LA diameter Z score lower than -4 was associated with a 19 times increased risk for vertical vein persistence.
Takeaway
Doctors studied kids with a heart problem to see why some had veins that didn't close after surgery. They found that if a certain heart measurement was too low, the veins were more likely to stay open.
Methodology
The study was a retrospective cohort analysis of 40 patients treated for TAPVR from 2005 to 2024.
Potential Biases
Potential biases may arise from reliance on medical records for data collection.
Limitations
The study's retrospective design and small sample size limit the generalizability of the findings.
Participant Demographics
The cohort included 40 patients, 26 males, with an average age of 2 days at diagnosis.
