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.
Résumé
De récents rapports sur les infections bactériennes survenant chez les patients ayant
subi l’implantation par cathéter de valves pulmonaires ont soulevé des préoccupations
sur le plus grand nombre d’événements par rapport à ce qui était observé antérieurement.
Nous rapportons le cas de 2 patients qui ont présenté une obstruction de la chambre
de chasse du ventricule droit secondaire à l’endocardite sur prothèse valvulaire pulmonaire
impliquant la périphérie des valves, une manifestation rarement décrite et peu commune.
L’un des patients a connu une détérioration rapide à court terme de l’évolution de
la maladie, tandis que l’autre patient a connu une évolution à long terme et indolente.
Les deux patients ont été traités en laboratoire de cathétérisme pour soulager les
obstructions, des traitements qui ont entraîné des résultats satisfaisants à court
terme.
