Micrococcus-associated central venous catheter infection in patients with pulmonary arterial hypertension.

Study Objectives: To determine the incidence of catheter-related infection in patients with pulmonary arterial hypertension (PAH) receiving epoprostenol (EPO), and to note an etiologic role for Micrococcus spp, which is rarely reported as a pathogen in the medical literature.

Design: Observational study.
