Unusual Case of Acute Type A Aortic Dissection During TAVR Bailout With a Self-Expanding Valve.

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
backgroundOver the past 2 decades, transcatheter aortic valve replacement (TAVR) has emerged as a widely accepted treatment for patients with severe aortic valve stenosis. Acute aortic dissection, although rare, is a life-threatening complication associated with TAVR. CASE SUMMARY: An older man with severe aortic stenosis underwent TAVR. During valve deployment, catheter manipulation caused intimal disruption, leading to acute type A aortic dissection (TAAD). Remarkably, the dissection spontaneously sealed after prosthetic valve placement, thereby avoiding emergency surgery. A 6-month follow-up computed tomography angiography scan showed no extension of the dissection. DISCUSSION: In the case we report, the dissection spontaneously sealed with the use of a prosthetic valve, a finding that reinforces the feasibility of nonsurgical management of iatrogenic TAAD during TAVR in select cases. TAKE-HOME MESSAGE: The use of a biological valve offers a novel perspective on the conservative management of iatrogenic aortic dissection in high-risk patients during TAVR.
