| Abstract;Purpose: We evaluated long-term prognosis of a thin bipolar pacing lead (Thin-Line, Intermedics, Angleton, TX, USA). Method: A total number of 138 co-radial, bipolar pacing leads (ThinLine; 37 atrial leads, 51 ventricular leads, ThinLine II steroid eluting lead; 21 atrial leads, 29 ventricular leads) were implanted in 90 Patients (Male 47; 73.+-.10, Female 43; 72.+-.13, SSS 34, AVB 49, Af brady 7) between 1994 and 2002 and followed for up to 120 months (6-120; 59.+-.34 months). Pacing threshold (capture voltage at 0.45 msec pulse width) and lead impedance were measured at implant, then 2, 6 and every 3 months. Results: Mean atrial pacing threshold of ThinLine II was significantly lower in postoperative 2-12 months compared with that of ThinLine. Mean ventricular pacing threshold of ThinLine II was significantly lower in postoperative 6-12 months compared with that of ThinLine. Both atrial and ventricular lead impedance of ThinLine II was significantly higher after implant. Battery longevity of 29 ThinLine Patients that led to replacement of the pacemaker generator was 78.+-.15 months. Conclusion; Long-term prognosis of a thin bipolar pacing lead was reliable. Both atrial and ventricular pacing threshold was significantly lower in ThinLine II steroid eluting lead. (author abst.) |
