电生理学研究和消融手术需要力量、稳定性和灵活性来操纵导管。我们之前描述了一种新型导管扭矩工具（Peritorq），可提高扭矩能力和稳定性，并减少用户肌肉疲劳。目的是评估导管完整性的措施，并没有扭矩工具到位使用多个诊断和消融导管在成年猪model.MethodsDiagnostic和消融导管插入通过股静脉或颈静脉到右心房，冠状窦（CS），右心室的区域。在使用和不使用扭矩工具的情况下获得了包括阻抗、感知和夺获阈值在内的电气测量值。消融病变（30秒）在不同的位置，使用灌溉和nonirrigated导管和测量记录，并没有扭矩tool.ResultsProcedures在8只成年猪进行。使用任何导管，在所有位置使用和不使用扭矩工具进行的测量均无显著差异。对于非灌注消融导管，PS三尖瓣处的最大（平均1.7 W，p= 0.03）和平均功率（平均9.1 W，p= 0.04）输送存在显著差异，但灌注或非灌注导管无其他差异。由操作者的主观评估显示，在可操作性，转移扭矩的能力，并在心脏space.ConclusionIn体内环境中的稳定性大幅改善，一种新的导管扭矩工具主观改善导管操作，并没有显着影响电生理导管的完整性。需要进一步研究，包括额外的导管和体内人体试验。
IntroductionElectrophysiology studies and ablation procedures require strength, steadiness, and dexterity to manipulate catheters. We have previously described a novel catheter torque tool (Peritorq) that improves torqueability and stability and decreases user muscle fatigue. The objective was to evaluate measures of catheter integrity with and without the torque tool in place using multiple diagnostic and ablation catheters in an adult porcine model.MethodsDiagnostic and ablation catheters were inserted through the femoral or jugular vein into areas of the right atrium, coronary sinus (CS), and right ventricle. Electrical measurements including impedance, sensing, and capture thresholds were obtained with and without the torque tool. Ablation lesions (30 s) were given at different locations using both irrigated and nonirrigated catheters and measurements were recorded with and without the torque tool.ResultsProcedures were performed in eight adult pigs. Measurements with and without the torque tool in all locations did not differ significantly using any of the catheters. With the nonirrigated ablation catheter there was a significant difference in maximum (mean 1.7 W,p= .03) and average power (mean 9.1 W,p= .04) delivery at the PS tricuspid valve, but there were no other differences with the irrigated or nonirrigated catheters. Subjective assessment by the operator revealed a substantial improvement in maneuverability, ability to transfer torque, and stability within the cardiac space.ConclusionIn an in‐vivo environment, a novel catheter torque tool subjectively improved catheter manipulation and did not have a significant impact on the integrity of electrophysiologic catheters. Further study including additional catheters and in‐vivo human testing is indicated.
