Blood cardioplegia or custodiol for myocardial protection during valvular or aortic surgery: a propensity score adjusted comparison.
Article in Journal of cardiothoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 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
backgroundThere is no solid evidence on the clinical benefits of blood cardioplegia or Custodiol™ in procedures other than coronary artery bypass grafting. We aimed to compare mortality and the risk of major cardiovascular events in patients undergoing valve or aortic surgery.
methodsThis retrospective single-center study included patients who underwent valve or ascending aortic surgery between 2016 and 2024. The sample was divided based on the type of cardioplegia for myocardial protection: Custodiol™ or blood cardioplegia. The comparison of outcomes between the two groups was adjusted using propensity score.
results2909 patients were included, with 1426 (49%) receiving Custodiol™. In a propensity score-matched analysis that included 930 pairs, we observed higher perioperative mortality in the blood cardioplegia group (5.3% vs. 2.9%, p = 0.014) and worse long-term survival (p = 0.004). In an IPTW analysis, we confirmed significant differences in favor of Custodiol™ for early mortality (-2.2%, 95% CI -4; -0.4), long-term mortality (2.6 years, 95% CI 2.1; 3.2), and renal failure (-4.7%, 95% CI -7.9; -1.6), and low cardiac output syndrome requiring mechanical circulatory support (-2.2%, 95% CI -3.6;-0.9), but a higher siks of postoperative denovo atrial fibrillation (6.8%, 95% CI 2.5;11).
conclusionsIn this retrospective study including patients undergoing on-pump valve and aortic surgery, Custodiol™ compared to blood cardioplegia was associated with lower short- and medium-term mortality, although no robust evidence was found for differences in other clinical events.
