Dedicated bifurcation stents for coronary bifurcation lesions: A systematic review and meta-analysis of randomized-controlled trials
Bibliographic record
Abstract
BACKGROUND: Percutaneous coronary intervention (PCI) of coronary bifurcation lesions (CBL) remains a challenge in contemporary practice due to the procedural and technical difficulties involved. We sought to review the current evidence on the safety and clinical outcomes of dedicated bifurcation stent (DBS) implantation in comparison with established treatment strategies for CBL-PCI. METHODS: We conducted a comprehensive search to identify randomized control trials (RCTs) reporting 1-year clinical and angiographic outcomes of patients undergoing CBL-PCI with DBS vs conventional CBL-PCI strategies. Random-effects meta-analyses were performed to estimate the effect of DBS compared with conventional CBL-PCI using aggregate data. RESULTS: A total of 5 RCTs comprising 1249 participants met the inclusion criteria. The use of DBS was comparable to conventional stenting techniques in terms of major adverse cardiovascular event (MACE) rate (odds ratio [OR], 1.28; 95% confidence interval [CI], 0.90- 1.82; I²=0%), all-cause mortality (OR, 0.80; 95% CI, 0.31-2.07; I²=0%), cardiac mortality (OR, 0.16; 95% CI, 0.02-1.39; I²=0%), myocardial infarction (OR, 1.26; 95% CI, 0.84-1.89; I²=0%), definite stent thrombosis (OR, 1.75; 95% CI, 0.36-8.52; I²=0%), cumulative target-lesion revascularization (OR, 1.39; 95% CI, 0.85-2.27; I²=0%), clinically driven target-lesion revascularization (OR, 1.23; 95% CI, 0.68-2.22; I²=0%), or target-vessel revascularization (OR, 1.43; 95% CI, 0.92-2.22; I²=0%). CONCLUSION: The present analysis suggests that CBL-PCI with DBS may be associated with similar 1-year clinical and angiographic outcomes compared with conventional CBL-PCI strategies. However, the low quality of evidence and limited follow-up warrant further studies to ascertain any significant differences in patient-important outcomes before the adoption of DBS into routine CBL-PCI practice.

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.
