Hospital procedural costs of surgical aortic valve replacement versus transcatheter aortic valve replacement in low-risk isolated aortic stenosis: a single-center analysis in japan.
Article in General thoracic and cardiovascular surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThe indications for transcatheter aortic valve replacement (TAVR) in patients with severe aortic stenosis (AS) are gradually expanding in Japan, with insurance coverage for low-risk patients approved in 2021. Although some reports have compared procedural costs, data addressing low-risk populations remain limited. This study aimed to assess in-hospital costs and outcomes of isolated TAVR versus surgical aortic valve replacement (SAVR) in low-risk patients with AS in real-world practice in Japan.
methodsWe retrospectively analyzed 128 low-risk (Society of Thoracic Surgeons [STS] score < 4%) patients with AS who underwent isolated TAVR (n = 80) or SAVR (n = 48) between August 2021 and December 2024 at The University of Osaka Hospital.
resultsBoth groups achieved excellent outcomes, with no in-hospital or 30-day mortality. Patients who underwent TAVR had shorter intensive care unit (ICU) stays (1 [1-1] vs. 3 [2-4] days) and shorter postoperative stays (7 [5-11] vs. 14 [11-18] days). However, total in-hospital and combined operative plus postoperative costs were significantly higher for TAVR (5.62 vs. 5.11 million Japanese Yen (JPY), p < 0.0001), (5.29 million vs. 4.80 million JPY, p = 0.0002).
conclusionsIn this cohort of low-risk patients with AS in Japan, TAVR was associated with significantly higher in-hospital costs than SAVR, despite shorter postoperative stay.
