Modified Del Nido "microplegia" reduces intraoperative, postoperative, and total blood products.
Article in JTCVS open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: Previous studies have shown that Buckberg microplegia reduces the need for intraoperative blood transfusion by minimizing hemodilution. However, this approach has been largely understudied in the context of Del Nido cardioplegia. We hypothesized that applying microplegia principles to Del Nido cardioplegia would similarly reduce transfusion requirements. Methods: A total of 192 consecutive patients undergoing isolated coronary artery bypass grafting with a single crossclamp and 1 dose of cardioplegia at a single institution between October 2023 and January 2025 were divided into 2 groups: standard Del Nido cardioplegia and modified micro Del Nido cardioplegia. All patients underwent retrograde autologous priming before initiation of bypass. Demographic factors, hematocrit levels, lactate levels, bypass time, crossclamp time, and transfusion of blood products including red blood cells, fresh-frozen plasma, platelets, and cryoprecipitate were compared. Additional outcomes of postoperative complications were measured. Results: Patients receiving modified micro Del Nido cardioplegia received significantly fewer units of intraoperative packed red blood cells ( Conclusions: Modified micro Del Nido cardioplegia reduces intraoperative and total blood product use and may further improve outcomes in larger studies.
