Quantifying the duration and variability of thoracic organ procurement cases.
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
Objective: To quantify and analyze key temporal intervals and variability in heart and lung thoracic organ procurement using multicenter registry data and assessing logistical complexity across operational phases and preservation modalities to inform strategies for optimizing transplant efficiency. Methods: This retrospective study analyzed timestamp data from 25,935 events across 7665 thoracic organ procurement cases (4992 heart, 2673 lung) performed between 2021 and 2025 using the Paragonix Mobile Application. Four temporal intervals were examined: total time away from transplant center, time at donor location, time to organ acceptance, and organ explant duration. Cases were stratified by organ type (heart and lung) and donor type (donation after brain death and donation after circulatory death). Results: Median total time away from transplant center was 7.4 hours for heart and 8.5 hours for lung procurement. Time at donor location showed was similar for each organ type (heart 3.2 hours vs lung 3.4 hours). Acceptance time demonstrated the shortest medians (heart 0.5 hours vs lung 0.8 hours). Organ explant duration was consistent (heart 2.0 hours vs lung 2.1 hours). All intervals exhibited right-skewed distributions with outliers. Donation after circulatory death cases demonstrated shorter surgical intervals compared with donation after brain death cases. Conclusions: This analysis provides empirical benchmarks for thoracic organ procurement timelines, revealing substantial real-world variability while demonstrating comparable durations between heart and lung procurement. These data may inform resource-allocation strategies, suggest a role for third-party procurement services, and optimize workflows for expanding donation after circulatory death programs.
