Résumé
Surgical techniques, such as the application of high-intensity focused ultrasound (HIFU), can be used for pulmonary vein isolation (PVI). We report a case of a 73-year old patient, in whom HIFU failed to achieve PVI but promoted the occurrence of a scar-related atrial tachycardia (AT). Voltage mapping of the left atrium revealed multiple gaps along the ablation line. Coherent mapping with visualization of velocity vectors allowed the correct interpretation and the targeted ablation of the AT. Cardiac surgery can promote scar-related AT. The coherent mapping function could simplify the mapping of scar-related AT in the future.

BACKGROUND
Surgical techniques, such as the application of high-intensity focused ultrasound (HIFU), can be used for pulmonary vein isolation (PVI).
CASE SUMMARY
We report a case of a 73-year old patient, in whom HIFU failed to achieve PVI but promoted the occurrence of a scar-related atrial tachycardia (AT). Voltage mapping of the left atrium revealed multiple gaps along the ablation line. Coherent mapping with visualization of velocity vectors allowed the correct interpretation and the targeted ablation of the AT.
DISCUSSION
Cardiac surgery can promote scar-related AT. The coherent mapping function could simplify the mapping of scar-related AT in the future.
