Abstract | BACKGROUND: AIM: To report early and one year results using Flextend catheters. MATERIAL AND METHODS: Retrospective analysis of all patients that received an implant of a Flextend catheter in the Unit. RESULTS: Forty one Flextend catheters were implanted in 24 patients, without acute displacement or clinical pericarditis. In 18 electrode catheters located in the right atrium the mean values for p wave, stimulation threshold and impedance at the moment of placement, were 2.9+/-1.4 mV, 0.8+/-0.4 V and 522+/-86 Ohms, respectively. The figures 24 hours after placement were 3.6+/-2.1 mV, 0.8+/-0.3 V and 612+/-69 Ohms, respectively. In 23 electrode catheters in the right ventricle, mean values at the moment of placement for R wave, stimulation threshold and impedance were 11.3+/-3.6 mV, 0.8+/-0.2 V and 756+/-108 Ohms, respectively. The figures 24 hours after placement were 3.6+/-2.1 mV, 0.8+/-0.3 V and 612+/-69 Ohms, respectively. In one patient, the stimulation threshold increased two months after placement and required a new intervention. CONCLUSIONS: Flextend catheters ca be placed successfully with a low rate of complications and stable function parameters on follow up.
