数据说明

Background: Recently, treatment of equine atrial tachycardia by three-dimensional electro-anatomical mapping (3D EAM) and radiofrequency catheter ablation (RFCA) has been described. Myocardial sleeves in the caudal vena cava and pulmonary veins are a potential trigger for initiation and perpetuation of atrial tachycardia and atrial fibrillation in the horse. Isolation of these myocardial sleeves by RFCA may be an effective treatment for these arrhythmias.
Objectives: To describe the feasibility of 3D EAM and RFCA to isolate caudal vena cava and pulmonary veins in adult horses using 3D mapping and a contact force (CF)-guided ablation system.
Study Design: In vivo experiment.
Methods: 3D EAM and RFCA was performed in five horses without cardiovascular disease under general anaesthesia, using the CF-guided system CARTO®3. Point-by-point RFCA aimed for isolation of caudal vena cava and pulmonary veins. Radiofrequency energy was delivered in power-controlled mode with a target power of 45 W, CF between 10-15 g and 30 ml/min irrigation rate, until an ablation-index of 450-500 was reached.
Results: In the right atrium, myocardial sleeves of the caudal vena cava were isolated (n=5). In the left atrium, isolation of ostium II (n=3), ostium III (n=1) and ostium I, II and III en bloc (n=1) was performed. Successful isolation was confirmed by entrance and exit block.
Main limitations: Horses were euthanized at the end of the procedure, so long term effects such as potential reconnection of isolated veins could not be studied.
Conclusions: This is the first description of 3D EAM and RFCA with CARTO® 3 in horses, thereby showing the technical feasibility and successful caudal vena cava and pulmonary vein isolation. CF measurement allowed monitoring of catheter-tissue contact, resulting in efficient acute lesion creation as confirmed by entrance and exit block. This is a promising treatment for cardiac arrhythmias in horses.
