Extracorporeal Membrane Oxygenation as a Bridge to Initial Medical Therapy in a Patient With Decompensated Pulmonary Arterial Hypertension Presenting With Biventricular Failure
Bibliographic record
Abstract
Extracorporeal membrane oxygenation (ECMO) can be used as a bridge to medical therapy in decompensated right heart failure due to pulmonary arterial hypertension (PAH). A middle-aged man with previously undiagnosed pulmonary hypertension was successfully bridged to intravenous prostanoid therapy with venoarterial ECMO support after presenting with cardiogenic shock and hypoxemic respiratory failure. Although the patient initially had biventricular failure, PAH was suspected due to underlying mixed connective tissue disease and disproportionate right ventricular dysfunction. On occasion, patients with PAH may present with biventricular failure. A high index of suspicion for PAH and serial reassessment of left ventricular function following correction of shock may demonstrate improvement in left ventricular function, allowing for initiation of pulmonary vasodilator therapy.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
