Use of plasmapheresis during cardiopulmonary bypass in a pediatric heart transplant of a patient with Failing Fontan Physiology: first case in Argentina.
Article in The journal of extra-corporeal technology, 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
backgroundA 17-year-old male patient diagnosed with a single ventricle, in a failed Fontan stage, was evaluated prior to heart transplantation. The patient had a panel-reactive antibody (PRA) for human leucocyte antigen (HLA) I of 18% and for HLA II of 37%, so the decision was made to administer three doses of immunoglobulin while waiting for a donor heart.
methodsOnce extracorporeal circulation was initiated, the apheresis machine extracted blood from the patient's venous drainage and returned it to the oxygenator reservoir. A total of 8278 mL of blood was processed, and 4224 mL of plasma was extracted. For replacement, 1341 mL of fresh frozen plasma and 2700 mL of 5% albumin were used. 75 mL of citrate-dextrose acid (CDA) was used as an anticoagulant. The procedure lasted 135 min.
resultsOn the tenth postoperative day, the PRA for HLA I and II was 0%. On the thirtieth postoperative day, a catheterization with endomyocardial biopsy showed no evidence of immunological rejection. An echocardiogram showed good function of the heart graft. One year later, a catheterization with endomyocardial biopsy showed no signs of humoral rejection. The patient is currently in the third-year post-transplant and continues to show no signs of rejection in their progression.
conclusionPlasmapheresis during cardiopulmonary bypass is a reproducible, safe, and effective technique. It may be indicated for sensitized patients on the heart transplant waiting list.
