PO-05-023 PROCEDURE TIME WITH A NOVEL COMPLETELY EXTRAVASCULAR TEMPORARY PACING LEAD SYSTEM

Temporary intracardiac pacing is required for emergency and also certain interventional procedures, including the increasingly indicated transcatheter aortic valve implantation. An important condition use of temporary pacemakers a short procedure time. Current are implanted through veins using fluoroscopy, and, when in situ, bedrest required. As an alternative to this traditional approach, novel, extravascular lead (EV-TPL) being studied, which may ultimately be inserted without fluoroscopy outside cardiac catheterization laboratory. The objective analysis was characterize effect implant experience on time number attempts place novel EV-TPL that paces fixation heart. In STEP III Study (NCT04538287), subjects undergoing permanent pacemaker or ICD implantation replacement received investigational EV-TPL. placed anterior mediastinum 2-3 cm skin incision made over intercostal space at left sternal margin. All leads were by one three collaborating operators. Four sequential cohorts associated with minor device modifications studied: Cohort 1 (n=8); 2 3 (n=7) 4 (n=8). achieve capture measured as difference between creation demonstrated 10 volts 1.5 milliseconds. Thirty-one patients included (52% female, 70±11 years, BMI 26±4 kg/m2). Median times successive were: 13.5 min [IQR 5.3, 45.8] 1; 9.0 7.3, 23.5] 2; 4.0 3.0, 27.0] 3; 5.5 5.0, 12.3] 4, shown Figure.
