Abstract
Abstract Portal hypertension may have major consequences on the pulmonary vasculature due to complex pathophysiological interactions between liver and lungs. Portopulmonary hypertension (PoPH) is characterized by the association of portal hypertension and pulmonary arterial hypertension (PAH). As progressive elevation of right ventricular afterload can lead to right heart failure, PoPH is a serious complication of portal hypertension, affecting functional status and prognosis of patients. Early detection by transthoracic echocardiography must be performed in symptomatic patients and in candidates for liver transplantation (LT). Right heart catheterization remains mandatory to confirm the diagnosis and exclude all other causes of elevated pulmonary pressures. The management of PoPH includes PAH-targeted therapies although few studies have evaluated these medications in this specific indication. The impact of LT on PoPH outcome remains complex and must be specified by future collaborative investigation. Although uncontrolled PoPH is associated with higher risk of postoperative right heart failure and death, stabilization, improvement, or normalization of pulmonary hemodynamics after LT seem to be achievable goals in selected patients with PoPH.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
