Transcatheter edge-to-edge repair in patients with mitral regurgitation and cardiogenic shock: a new therapeutic target
Bibliographic record
Abstract
PURPOSE OF REVIEW: Cardiogenic shock with significant mitral regurgitation portends a poor prognosis with limited therapeutic options. Herein, we review the available evidence regarding the patient characteristics, management, impact of transcatheter edge-to-edge repair (TEER) on hemodynamics, and clinical outcomes of patients with cardiogenic shock and mitral regurgitation. RECENT FINDINGS: Several observational studies and systematic reviews have demonstrated the feasibility and safety of TEER in cardiogenic shock complicated by degenerative or functional mitral regurgitation. Surgical interventions for mitral regurgitation remain limited owing to the risk profile of patients in cardiogenic shock. TEER has been studied in both degenerative and functional mitral regurgitation and remains feasible in the critically ill population. Moreover, TEER is associated with reduction in mitral regurgitation and improvement in-hospital and long-term mortality. SUMMARY: TEER remains a promising therapeutic option in cardiogenic shock complicated by significant mitral regurgitation, but additional research is required to identify patient and procedural characteristics, hemodynamic parameters, and the optimal time for intervention. Moreover, future randomized controlled trials are in progress to evaluate the potential benefit of TEER against medical management in cardiogenic shock and mitral regurgitation.

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.
