Stratos LV/LV-T Technical Manual 29

Primary Endpoint—Complication-free Rate (Safety)

The safety of the Stratos LV was evaluated based on complications (adverse events that require additional invasive intervention to resolve) related to the implanted CRT system which includes the Stratos LV, the right ventricular, the left ventricular lead, lead ventricular lead adapters (if used) and the implant procedure. The target complication-free rate at six months is 85%.

13 complications in these categories were seen in 11 patients with cumulative enrollment duration of 783.5 months (64.4 patient-years). 14.7% of the patients had a reported complication in these categories. The rate of complications per patient-year is 0.20. Details of the Stratos LV complications in the AVAIL CLS/CRT study are listed in Table 4.
