Long-term outcomes of left coronary artery reconstruction by Svensson's modification to the Bentall procedure versus button reconstruction.

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
objectiveWe aimed to evaluate the long-term outcomes of long-interposed graft replacement of the left coronary artery (Svensson's modification) in the modified Bentall procedure compared with button reconstruction using propensity score matching analysis.
methodsIn total, 101 patients who underwent the modified Bentall procedure with Svensson's modification (S group, n = 54) or button coronary artery reconstruction (B group, n = 47) between 1992 and 2024 were included. In the first era, we routinely performed Svensson's modification; recently, the procedure was performed when mobilization of the left coronary artery was difficult.
resultsThe median age was relatively lower in the S group (63.0 [50.5-68.8] years) than in the B group (66.0 [56.5-1.83] years). There were no significant differences in in-hospital mortality between the two groups, with two deaths recorded in each group. Five and four patients in the S and B groups, respectively, required additional intraoperative and postoperative interventions for button-reconstructed coronary arteries. In the long-term, both groups had no additional interventions for the reconstructed coronary ostia. In the S group, overall survival rates were 78.2, 67.6, and 60.8% at 10, 15, and 20 years, respectively, and the reoperation rates were 14.2, 18.3, and 18.3% at 10, 15, and 20 years, respectively. Propensity score matching showed no significant differences in in-hospital mortality, overall survival, or reoperation rates between both groups.
conclusionsSvensson's modification of the Bentall procedure provided good long-term outcomes, equivalent to those of button reconstruction; it may provide good outcomes in patients with difficult mobilization of the left coronary artery.
