Sex differences in outcomes among patients undergoing transcatheter atrial septal defect closure: Do they benefit equally?
Bibliographic record
Abstract
Abstract Background Although sex differences in congenital heart disease are prevalent and relevant, there is limited research on their role in atrial septal defect (ASD) closure. We aimed to investigate sex differences in baseline characteristics, procedural and long-term outcomes of patients with transcatheter ASD closure. Methods Data from adult patients undergoing ASD closure between 2005-2016 were retrospectively analyzed. Results Of the 853 patients included, 281 (32.9%) were male and 572 (67.1%) were female. Females were more symptomatic at presentation than males (p < 0.001). Males had a higher frequency of cardiovascular comorbidities than females (p < 0.001). Although echocardiographic right ventricular (RV) diameter relative to body surface area was equal in males and females (2.49 cm/m2 versus 2.57 cm/m2; p = 0.072), males had more RV dysfunction (12.1% versus 7.6%; p = 0.028). In contrast, females had higher RV systolic pressures (39.71 mmHg versus 37.23 mmHg; p = 0.025), and were more likely to have moderate to severe tricuspid regurgitation (15.4% versus 8.9%; p = 0.007). Males had larger defects with use of larger implants (p < 0.05). Procedure-related complications were rare and did not differ by sex. At 12-month follow-up, both male and females showed comparable decreases in RV diameter (-0.57 cm versus -0.59 cm; p = 0.751), RV systolic pressure (-4.57 mmHg versus -6.31 mmHg; p = 0.094), and severity of tricuspid regurgitation (p = 0.173; Figure). After a mean follow-up of 3 years (SD = 5), no significant differences were observed in the incidence of death (incidence rate ratio (IRR) = 0.49 [95% CI 0.27-0.83]; p = 0.402), new onset atrial fibrillation (IRR = 3.22 [95% CI 2.57-3.99]; 0.063), cardioversion or ablation (IRR = 0.40 [95% CI 0.20-0.71], p = 0.335), stroke/TIA (IRR = 0.29 [95% CI 0.12-0.56]; p = 0.745), and pacemaker implantation (IRR = 0.29 [95% CI 0.12-0.57], p = 0.728). Conclusions Although patient profiles differed by sex, procedural and long-term outcomes were comparable, suggesting that transcatheter ASD closure can be safely performed in both males and females.Figure.Sankey Plot

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
