It was reported that at the end of a completed cryo ablation procedure, the mapping catheter could not be removed from the left superior pulmonary vein (lspv) which had multiple side branches.The mapping catheter seemed to be "hooked" on a structure within the patient's anatomy.After multiple different maneuvers, the mapping catheter was able to be removed.A computerized tomography (ct) was performed and a small hemorrhage was observed in the lower lobe of the lung.The physician suspected that the hemorrhage was due to the maneuvering of the mapping catheter.The patient was hospitalized with mild thoracic pressure.The following day, the patient was stable without any symptoms of a hemorrhage. no further patient complications have been reported as a result of this event.
