WIN Gulf TAVR Registry: Describing Sex Differences in Patient Characteristics, Prognosis, and Outcomes
Bibliographic record
Abstract
Background: Several international registries have examined outcomes in women undergoing transcatheter aortic valve replacement (TAVR). However, none of these studies included women from the Gulf region. The Women IN Gulf Transcatheter Aortic Valve Replacement (WIN Gulf TAVR) registry aimed to examine sex-based differences in patient characteristics and outcomes in patients undergoing TAVR in the region. Methods: This registry is a prespecified subanalysis of the main Gulf TAVR registry. Baseline characteristics, procedural details and success, and 1-year outcomes were recorded. The primary outcome consisted of a composite of all causes of death, myocardial infarction (MI), and rehospitalizations at 1 year. The secondary outcomes were a composite of the individual components of the primary composite. Results: A total of 347 women (44% of the Gulf TAVR registry) were included in the final analysis, with a mean age of 74.1 ± 9.1 years; mean ejection fraction of 56.20% ± 10.52%; and mean Society of Thoracic Surgeons score of 5.30 ± 4.35. The composite primary end point occurred in 12.4% (95% CI, 9.3-16.2). The individual components of the primary end point were as follows: death, 4.3% (95% CI, 2.6-7.0); MI, 1.1% (95% CI, 0.4-2.9); and rehospitalization, 9.8% (95% CI, 7.1-13.3), with 7.2% (95% CI, 4.9-10.4) related to cardiac causes. Conclusions: Women in the WIN Gulf TAVR registry had outcomes and baseline characteristics similar to men. Although higher rehospitalizations for cardiac causes and MI at 1 year in women were noted, the overall survival was better in women. These observations warrant a larger cohort to identify the drivers of events.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
