| Description: |
Introduction: Ablation of atrial fibrillation is frequently aided by electro anatomical mapping systems. One system in common use isEnSite NavX™ (St. Jude Medical, Inc., Minneapolis MN). This relies on tranthorasic impedance using external patches and an internal catheter as a reference. The model created is dependent on stability of the reference catheter. We report on the use of an Oesophageal temperature probe as such a reference catheter and its stability. Methods: 21 consecutive ablations for atrial fibrillation, both paroxysmal and persistent were carried out. catheters were positioned in the left atrium then the oesophageal temperature probe was positioned. Once in position we used the fluoroscopy equipment to create still images in LAO 30 and RAO 30. The position of the temperature probe to a fixed point on the spine was measured. The ablation was then performed at the operators discretion. This was always a wide area cirmcuferential ablation of the veins, but variously included ablation of complex fractionated electrograms and linear lesions. On occasion cardioversion was necessary. At the end of the case the position of the temperature probe was again measured in LAO and RAO projections. Results: The movement of the temperature probe was minimal. Mean displacement was 3.38mm vertically (+/−2 standard deviations = 1.08mm) and 2.38 horizontally (+/−1.26mm). The largest displacements occurred post cardioversion. There were no cases where the geometry had to be reset due to catheter shift Conclusion: An oesophageal temperature probe can be successfully used as a stable reference for geometry. |
