Burkholderia cepacia infective endocarditis of a double-layer transcatheter pulmonary valve.

Burkholderia cepacia is a rare cause of prosthetic valve endocarditis. We report an 18-year-old male with Tetralogy of Fallot and two sequential transcatheter pulmonary valves (Melody and Myval), presenting with persistent bacteraemia unresponsive to antibiotics. Surgical explantation of both valves with homograft replacement and tricuspid repair achieved complete recovery, emphasising surgery in refractory infections.
