Early and 3-Year Outcomes of Frozen Elephant Trunk Procedure with Evolving E-vita Hybrid Grafts: A Retrospective Single-Centre Cohort Study over 11 Years.

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/
objectivesThe frozen elephant trunk (FET) technique is a cornerstone procedure for complex thoracic aortic pathologies. This single-center retrospective study evaluates early and midterm outcomes of total arch replacement (TAR) using three generations of the E-vita Open hybrid prosthesis over 11 years.
methodsFrom January 2013 to June 2024, 51 patients underwent TAR with the FET technique using the E-vita Open prostheses. Exclusion criteria were isolated ascending or descending aortic replacement, partial arch replacement, TAR without FET, and use of other stent grafts. We analyzed outcomes including in-hospital mortality, survival, stroke, spinal cord injury, and renal complications across three prosthesis generations.
resultsThe cohort included 52.9% males, with a mean age of 61.5 ± 10.51 years. FET as reoperation was performed in 52.9% patients. In-hospital mortality was 7.8% and, unexpectedly, only occurred with the newest E-vita Open Neo (23.5%), despite this being the latest generation. Overall survival was 72.5% at one year, 60.8% at two years, and 54.9% at three years. Stroke occurred in 17.6% with marked variation by pathology: 0% in dissection, 31.6% in aneurysm, and 13.6% in combined disease. Spinal cord injury occurred in 7.8%. Re-operation was a significant risk factor for complications and was strongly associated with renal complications (85.7% of dialysis patients) but not mortality. Secondary endovascular procedures were required in 49% of patients.
conclusionsThe FET technique with E-vita Open prostheses demonstrates acceptable outcomes in high-risk patients with complex aortic pathologies. While perioperative morbidity is significant, particularly in reoperative cases, it varies significantly by underlying pathology and prosthesis generation, with unexpected trends suggesting that technological advancement does not automatically translate into improved outcomes. Despite this, the procedure enables comprehensive management of extensive aortic disease through a staged approach.
