Local anesthesia with conscious sedation,
does it really help with Equivalent 30-day clinical outcomes versus general anesthesia during transfemoral TAVI?
research showsThe grade is B. The 30-day composite occurred in 27.2% (59/217) versus 26.4% (58/220), difference 0.8 points (90% CI -6.2 to 7.8), entirely within the prespecified ±10-point equivalence bounds.

Useful facts when choosing a product
- General anesthesia and conscious sedation are real options for TAVI in Korea.
- The 90% CI of -6.2 to 7.8 points stayed within ±10.
What the research actually shows
The 2×2 factorial trial randomized 447 patients; 218 and 220 were analyzed in the anesthesia comparison. The investigators wrote, 'We chose a δ of 10% considering it clinically meaningful.' Four-gate bias review: ① defect: unblinded subjective endpoint; ② listed item: unblinded subjective endpoint; ③ the trial was open label and infection depended on an antibiotic-treatment decision; ④ anesthesia blinding was impossible, but independent blinded assessment of antibiotic necessity was feasible, so it counts once. Equivalence design itself is not a listed defect and was not added. Funding came from the German Heart Research Foundation and Helios Health Institute; disclosures included some author relationships with Edwards and Medtronic, but no company trial funding was identified. Verdict 1731 is A with 84 points and asks whether to perform TAVR in severe stenosis; verdict 2382 is B with 76 points and asks when to perform early TAVR in asymptomatic disease. This verdict asks which anesthesia to use once TAVI is performed.
Why this is classified as B (72)
One publicly funded clinical-event equivalence RCT with an open subjective component gives B with 72 points.
Counterpoint. The mixed composite and 30-day horizon limit interpretation.
Rejudgment record. New verdict — One RCT meeting both prespecified equivalence bounds, with an open subjective composite component counted
| Endpoint | H | Hard endpoint - actual events such as death |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (B).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Equivalent 30-day composite clinical outcomes | B | The entire 90% CI stayed within ±10 points. |
