Adjunctive use of the Rinspiration system for fluidic thrombectomy during primary angioplasty: The Rinspiration international registry
Bibliographic record
Abstract
BACKGROUND: Atherothrombotic embolization during primary percutaneous coronary intervention (PCI) induces microvascular obstruction and reduces myocardial tissue reperfusion. A variety of thrombectomy devices have been evaluated as an adjunct to primary PCI in patients with ST-elevation myocardial infarction (STEMI) to reduce distal embolization. Results have been inconsistent and difficult to predict. The aim of this study was to investigate the safety and efficacy of an innovative thrombectomy device, the Rinspiration System, which simultaneously "rinses" the vessel with turbulent flow and aspirates thrombus. METHODS: We prospectively enrolled 109 patients at six academic institutions in three countries referred for primary or rescue PCI for STEMI presenting within 12 hr of symptom onset. The primary endpoint was >or=50% ST-segment elevation resolution (STR) measured 60 min after PCI by continuous electrocardiographic recording, Secondary end points included STR > 70% at 60 min, final TIMI flow, myocardial blush score, and 30-day major adverse cardiac events (MACE). RESULTS: Mean symptom-to-PCI time was 4.7 +/- 2.7 hr. Rinspiration was successfully delivered in 98% of cases. Final TIMI three flow was achieved in 89% of patients and myocardial blush >or=2 in 78%. Rates of STR >or= 50% and >70% at 60 min were 97 and 80%, respectively. No device-related complications were observed. Thirty-day MACE rate was 4.6%. CONCLUSIONS: This international multicenter registry demonstrates that the adjunctive use of Rinspiration during primary PCI is safe and feasible. The excellent STR data compare favorably with results of previous trials using different devices for thrombus management, indicating a potential clinical benefit.

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.
