Total aortic arch replacement using the Thoraflex Hybrid device: evolution from investigational to federally approved use in the United States.
Article in Annals of cardiothoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: After the US Food and Drug Administration (FDA) approved the Thoraflex Hybrid device in April 2022, hybrid devices to facilitate total arch replacement (TAR) became commercially available in the United States. However, little is known about how the Thoraflex device has been used since then. We present our experience (2016-2025) with this device. Methods: At our practice, 62 patients [median age, 65 (54-73) years] underwent frozen elephant trunk (FET) TAR with the Thoraflex device: 14 under an investigational device exemption (IDE) (2016-2018) and 48 after FDA approval (2022-2025). Both Ante-Flo (straight) and Plexus (branched) models were used. Results: Patients with aortic dissection were common (n=38; 61%). Many patients had prior open or endovascular aortic repair (n=28; 45%). Initial cannulation was commonly done via the innominate artery (n=30; 48%) or the right axillary artery (n=22; 36%). Both branched and island strategies were used to reattach the brachiocephalic arteries. Selectively, left subclavian artery (LSCA) bypass was performed before TAR in 18 patients (29%). The distal anastomosis was performed proximal to the LSCA in 27 repairs (43%). A short (10-cm) endograft extension was used in most cases (n=49; 79%). Eight (13%) patients underwent concomitant aortic root replacement. Overall, four patients (7%) had operative deaths, and three (5%) were discharged with stroke or persistent need for renal dialysis. Two patients had spinal cord deficits that resolved before discharge. Twenty-five downstream extensions (12 open, 13 endovascular) were needed in 22 patients; two patients underwent more than one repair. After discharge, seven additional patients died within one year of surgery. Conclusions: TAR is a complex procedure. Patients requiring such repair tend to have substantial disease that often eventually necessitates subsequent downstream aortic repair, especially when dissection is present. Using the Thoraflex Hybrid device in TAR results in good early outcomes and provides a reliable base for extension.
