Aortic Root Rupture during Transcatheter Aortic Valve Implantation in a Patient with Idiopathic Thrombocytopenic Purpura: Utility of Transesophageal Echocardiography in Early Detection and Description of a Semiconservative Surgical Management Approach
Bibliographic record
Abstract
/L underwent transesophageal echocardiography (TEE)-guided transcatheter aortic valve implantation using a femoral approach. Post valve deployment, a new pericardial effusion was noted which was successfully drained. Despite this, the patient became hypotensive needing vasopressor support with reaccumulation of pericardial fluid. Emergent sternotomy was performed and a perforation of the right ventricular apex was noted which was sealed with a pledgeted suture. Continued bleeding prompted further exploration; the aorta was seen to be mottled in conjunction with clear aortic root hematoma on TEE and a diagnosis of root rupture was made. This was semiconservatively managed without conversion to a full aortic root repair or replacement procedure. Multiple sutures were applied to the periaortic space and the bleeding sealed with use of BioGlue (Cryolife Inc., Kennesaw, GA) and Surgicel (Ethicon Inc., Somerville, NJ). The postoperative course was stable and the patient remained well at 3-month follow-up.

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.
