1 · What the graph read from it

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.

2 · The registry

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

introductionThere is no standard protocol for management of organ preservation for orthotopic, life-sustaining cardiac xenotransplantation, particularly for hearts from pediatric sized donors. Standard techniques and solutions successful in human allotransplantation are not viable. We theorized that a solution commonly used in reparative cardiac surgery in human children would suffice by exploiting the advantages inherent to xenotransplantation, namely the ability to reduce organ ischemic times by co-locating the donor and recipient.

methodsOrthotopic cardiac xenotransplantation was performed from genetically engineered pigs to size matched baboons. A dose of modified Del Nido cardioplegia initiated donor heart arrest and was followed by a second dose mixed with recipient blood prior to implant. Hemodynamics and cardiac function were tracked with a combination of invasive and non-invasive measures.

resultsMean ischemic time and cardiopulmonary bypass times were 54.1 ± 14.6 and 84.1 ± 14 min respectively. The ejection fraction following chest closure was preserved at >50% for all animals. This finding persisted at 48hours. Mean inotropic score at 24 h post-implant was 9.7 ± 3.

conclusionDel Nido cardioplegia solution when combined with short graft ischemic times demonstrates promising outcomes to avoid primary graft dysfunction for cardiac xenografts in a small animal model of life-sustaining orthotopic cardiac xenotransplantation. Ex vivo perfusion systems may be unnecessary for successful clinical implementation of this evolving technology.
