Aortic Dissection After TAVR: Mechanisms, Management, and Outcomes From a Single-Center Experience.
Article in JACC. Case reports, 2026. 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
backgroundAortic dissection is a rare but catastrophic complication of transcatheter aortic valve replacement (TAVR), with limited data on mechanisms, management, and outcomes.
objectivesTo describe the incidence, mechanisms, management, and outcomes of aortic dissection complicating TAVR.
methodsWe retrospectively analyzed patients developing perioperative acute aortic dissection during TAVR between 2014 and September 2025. The primary outcome was in-hospital mortality.
resultsAmong 2,646 TAVR procedures, 10 patients (0.38%) developed acute aortic dissection. Mean age was 83 ± 8 years, 70% were female, and mean Society of Thoracic Surgeons risk of mortality was 3.6% ± 3.4%. Six dissections (60%) were Stanford type A and 4 (40%) type B. Suspected mechanisms included delivery system manipulation (60%) and wire/catheter trauma (40%). Management consisted of open surgery (30%), endovascular/hybrid intervention (40%), or conservative treatment (30%). In-hospital and 30-day mortality were 40%.
conclusionsAortic dissection after TAVR is rare but associated with substantial early mortality, requiring prompt recognition and individualized multidisciplinary management.
