Impact of downtime on surgical outcomes after repair of acute type A aortic dissection presenting with cardiopulmonary arrest.

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
Objective: The management of acute type A aortic dissection with cardiopulmonary arrest remains controversial. We evaluated the impact of downtime on outcomes after aortic repair in this high-risk population. Methods: We retrospectively reviewed 711 patients with acute type A aortic dissection admitted between August 2003 and December 2024. Patients were categorized according to the presence of cardiopulmonary arrest and whether immediate aortic repair was performed. Among surgically treated patients with cardiopulmonary arrest, downtime was defined as the interval from collapse to return of spontaneous circulation or establishment of extracorporeal cardiopulmonary resuscitation. Early mortality, long-term survival, and discharge destination were analyzed. Results: Among 222 patients with cardiopulmonary arrest, 30 underwent aortic repair and 192 did not. Aortic repair was performed in 489 patients without cardiopulmonary arrest. Early mortality was 100% in the cardiopulmonary arrest without surgery group, 40.0% in the patients with surgery group, and 5.1% in the noncardiopulmonary arrest group ( Conclusions: Acute type A aortic dissection presenting with cardiopulmonary arrest carries exceptionally high risk. However, discharge home and long-term survival may be achieved in selected patients when downtime is short and immediate aortic repair follows successful resuscitation.
