Hospital Variation in Aortic Valve Replacement Approach Selection for Aortic Stenosis in Patients Under 65.
Article in European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesAlthough surgical aortic valve replacement (SAVR) has a class 1 A recommendation for treating severe aortic stenosis in patients <65 years, transcatheter aortic valve replacement (TAVR) in this population is increasing. This study evaluates the impact of hospital variation in TAVR use in patients <65 years on clinical outcomes.
methodsUsing US 3-state data from 2013 through 2021, we assessed the hospitals' preference for TAVR vs SAVR by generating the observed-to-expected TAVR ratio. Hospitals were ranked into tertiles based on their ratio. The risk of mortality, stroke, infective endocarditis (IE), and permanent pacemaker implantation (PPI) for patients undergoing aortic valve replacement (AVR) in each tertile was assessed at 30 days and 6 years using logistic regression and Cox-proportional hazard models.
resultsAmong 189 hospitals, 103 were in the low, 55 in the medium, and 31 in the high-tertile. Patients who underwent AVR in the high tertile had lower rates of comorbidities than patients in mid or low tertiles. Patients at high and medium ratio hospitals had higher rates of PPI at 30 days than those from low TAVR-use hospitals (17% vs 7.6% vs 5.6%, P < .001). Patients in the high vs low tertile experienced a higher 6-year risk-adjusted mortality (8.1% vs 5.3%, HR: 1.63 [1.37-1.93], P < .001), stroke (2.2% vs 1.1%, sub-distribution hazard ratio [sHR]: 2.15 [1.50-3.06], P < .001), and IE (2.9% vs 0.3%, sHR: 9.91 [5.59-17.56], P < .001).
conclusionsThe decision on TAVR utilization in patients younger than 65 should be made carefully considering the patient's clinical profile and life expectancy.
