Endo-Aortic Clamp for Minimally Invasive Redo Mitral Valve Surgery: Early Outcome.
Article in Journal of cardiovascular development and disease, 2024. 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
objectiveRedo mitral valve surgery still represents a challenging and high-risk procedure in cardiac surgery. The incidence of cardiac structural injuries during re-sternotomy remains consistent and is reported to be an independent risk factor for hospital mortality. Minimally invasive cardiac surgery with retrograde femoral arterial perfusion and endo-aortic clamping avoids re-entry injuries and reduces the requirement for dissection of adhesions and the risk of damage to cardiac structures. The aim of this study is to analyze redo patients undergoing mitral valve surgery with retrograde arterial perfusion and endo-aortic clamping setting.
methodsA retrospective analysis was performed on patients undergoing surgery from 2006 to 2022. Exclusion criteria were more than mild aortic regurgitation, moderate-to-severe peripheral vascular disease, dilated ascending aorta, and a lack of preoperative vascular screening. The primary outcome was perioperative mortality.
resultsTwo hundred eighty-five patients were analyzed. Mean age was 63.8 ± 13.3 years, mean EuroSCORE was 16.5 ± 14.5%, and one quarter of the patients had undergone two or more previous procedures via sternotomy. Perioperative mortality was 3.9% (11/285). Stroke was reported in six (2.1%) patients. Median intensive care unit and hospital length of stay were 1 and 8 days, respectively.
conclusionsEndo-aortic clamping setting in redo MV surgery avoids re-entry injuries and allows the surgeon to clamp the aorta and deliver the cardioplegia with minimal dissection of adhesions. In high-volume and experienced centers, this approach can be applied safely and effectively and may in the near future become the standard of care for redo mitral valve surgery.
