Novel Applications of a Percutaneous Dual‐Lumen Cannula Beyond a Right Ventricular Assist Device
Bibliographic record
Abstract
The ProtekDuo's dual-lumen design combined with its ability to be inserted percutaneously allows for its use in a wide variety of clinical scenarios. Therefore, it was chosen to be used as the venous cannula on cardiopulmonary bypass to treat a patient who had a high risk of right ventricular failure and a need for mechanical circulatory support postoperatively. Biventricular failure occurred during the patient's course in hospital, and the ProtekDuo was used in a novel hybrid configuration using both the distal port on the ProtekDuo and the aortic cannula as outflow cannula for the extracorporeal membrane oxygenation circuit, and the proximal port on the ProtekDuo was used as the venous return. Gradually increasing ProtekDuo distal outflow and decreasing aortic cannula outflow facilitated an isolated and progressive loading of the left ventricle while maintaining support for the right ventricle. In total, four separate mechanical circulatory support configurations were used to support and optimize the patient's hemodynamics. The ability to utilize a single cannula in a hybrid manner may be useful in patients requiring controlled weaning of mechanical circulatory support.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
