Efficacy of a balloon‐expandable vascular access system in transfemoral TAVI patients
Bibliographic record
Abstract
BACKGROUND: Vascular complications (VC) are a serious and frequent complication of transfemoral transcatheter aortic valve implantation (TAVI) and result in increased morbidity and mortality. It has been suggested that newly developed vascular sheaths may increase the ability to perform transfemoral TAVI in patients with normal and access-limiting peripheral artery disease (PAD) and reduce vascular complications. AIMS: We sought to assess the safety and efficacy of the 19 French (F) SoloPath balloon-expandable transfemoral vascular access system in patients who underwent transfemoral TAVI at our center between 2011 and 2014. METHODS AND RESULTS: Single-center retrospective study of 90 patients who underwent transfemoral TAVI with the use of the SoloPath sheath. Patients were categorized into two groups according to a sheath to femoral artery ratio (SFAR) of less than or equal to 1.05, or greater than 1.05. Overall, the incidence of major bleeding complications was low, 4.4%. No significant differences were found in technical or procedural success rates (100% in both groups and 100% vs. 91.3; P = 0.09; respectively), total vascular complications (20.8 vs. 21.7; P = 0.92) or total bleeding complications (20.8 vs. 30.4; P = 0.36 between those with SFAR greater or less than 1.05. CONCLUSIONS: The use of the SoloPath balloon-expandable sheath is feasible and safe even in patients with SFAR > 1.05, showing no increased vascular or bleeding complications compared to patients with larger vascular access. © 2016 Wiley Periodicals, Inc.

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.
