Monitoring pulmonary pressures during long-term continuous-flow left ventricular assist device and fixed pulmonary hypertension: redefining alleged pathophysiological mechanisms?
Pulmonary hypertension (PH) type II (classified by the World Health Organization) is a common complication in chronic left-sided heart failure. In advanced heart failure therapy, fixed PH is an absolute contraindication for heart transplantation after which a left ventricular assist device (LVAD) is the only remaining option. With remote monitoring, we can now continuously evaluate the pulmonary artery pressures during long-term LV unloading by the LVAD. In this case, we demonstrate that fixed PH can be reversed with LVAD implantation, whereby previous thoughts of this concept should be redefined in the era of assist devices
Mycobacterium chelonae, an ‘atypical’ cause of an LVAD driveline infection
We describe the first patient with a left ventricular assist device (LVAD) driveline infection caused by Mycobacterium chelonae presenting with persistent infection despite conventional antibiotics. Treatment was successful with surgical debridement, driveline exit relocation, and a 4-month period of antibiotics. In the case of a culture-negative LVAD driveline infection, non-tuberculous mycobacteria should be considered. This case illustrates tha
