title: Bacterial Endocarditis Manifesting as Outflow Tract Obstruction in Two Patients Implanted With Percutaneous Prosthetic Pulmonary Valves.
abstract: Recent reports on bacterial infections occurring in patients with transcatheter-implanted pulmonary valves have raised concerns about higher than previously perceived occurrences of these events. We report on 2 patients who presented with right ventricular outflow tract obstruction secondary to prosthetic pulmonary valve endocarditis involving the valve's periphery, a rarely described and uncommon manifestation. One patient had an acute and rapidly deteriorating disease course, whereas the other had a more chronic and indolent course. Both patients were treated in the catheterization laboratory to relieve the obstructions, treatments which resulted in satisfactory acute results.
