Unusual Presentation of Isolated Nonbacterial Thrombotic Tricuspid Valve Endocarditis in Systemic Lupus Erythematosus With Secondary Antiphospholipid Syndrome: A Case Report
Bibliographic record
Abstract
Nonbacterial thrombotic endocarditis (NBTE), or marantic endocarditis, is one of the most prevalent cardiac presentations seen in patients with systemic lupus erythematosus (SLE). It is a condition that is characterized by noninfectious lesions affecting cardiac valves. The most common sight for this disease to affect is the left-sided mitral and aortic cardiac valves. It rarely involves the right-sided tricuspid valve. However, having a secondary condition that increases risk for hypercoagulability can potentiate the severity and frequency of cardiac valvular disease in SLE. In this report, the authors describe a rare case of a patient who presented with clinically symptomatic isolated-sterile tricuspid valve vegetations likely due to antiphospholipid syndrome (APLS) on top of SLE. Optimal medical and surgical managements of these vegetations are not well defined. Criteria call for surgical intervention in infective endocarditis when there are severe heart failure or valve dysfunction, prosthetic valve infection, recurrent systemic emboli, large mobile vegetations, and other detrimental complications. However, intervention for sterile vegetations should also be discussed if the patient can benefit from it clinically and if it can improve quality of life. The authors discuss this case in the context of the relevant medical and surgical literature.

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.
