Prosthetic Aortic Valve Endocarditis Caused by Burkholderia cepacia complex: A Case Report
Bibliographic record
Abstract
Prosthetic valve endocarditis (PVE) is a rare condition caused by infection of prosthetic heart valves (PHV) or repaired native valves. Onset from the time of implantation can be used to classify it into early and later categories. Gram-positive cocci are the predominant cause of early PVE (less than one year after implantation), though other less common organisms can also cause PVE. We report a case of early prosthetic valve endocarditis caused by gram-negative Burkholderia cepacia complex (BCC). This multidrug-resistant organism is an exceedingly rare cause of PVE. Only a handful of cases have been reported in medical literature. Its inherent resistance to the commonly used treatment modalities presents a unique challenge. Often, surgical intervention and removal of the prosthesis are required to ensure resolution. We present a case of prosthetic aortic valve endocarditis caused by Burkholderia cepacia (B. cepacia) that showed an excellent response to combination antibiotics.

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.
