When a 5f 100cm vertebral tempo agua diagnostic catheter was withdrawn in an interventional procedure, the patient's vagus reflex was too strong, heart rate slowed down, and the patient lost consciousness.The patient has been discharged from the hospital without any adverse consequences after reasonable treatment.The product that caused the adverse event has been discarded by the hospital and cannot be returned, the lot number is unknown.Symptoms such as slow heart rate and transient loss of consciousness after stimulation of the vagus reflex mentioned in the reported information are transient, mainly due to the long time of pressing the puncture port and excessive pressure, which is not directly related to the tempo catheter.The device will not be returned for analysis.

Additional b5 narrative: the lot number is not available.The low blood pressure was not treated.The patient regained consciousness and the blood pressure returned to normal before discharge.There were no anomalies noted on the tempo catheter before use.The product was inspected and prepped according to the instructions for use.Additional patient and procedural details were requested but were unknown.The product will not be returned for analysis.As reported, when a 5f 100cm vertebral tempo agua diagnostic catheter was withdrawn in an interventional procedure, the patient's vagus reflex was too strong, heart rate slowed down, and the patient lost consciousness.The patient has been discharged from the hospital without any adverse consequences after reasonable treatment.The product that caused the adverse event has been discarded by the hospital.The lot number is unknown.Per the medical staff, "symptoms such as slow heart rate and transient loss of consciousness after stimulation of the vagus reflex mentioned in the reported information are transient, mainly due to the longtime of pressing the puncture port and excessive pressure, which is not directly related to the tempo catheter." the low blood pressure was not treated.The patient regained consciousness and the blood pressure returned to normal before discharge.There were no anomalies noted on the tempo catheter before use.The product was inspected and prepped according to the instructions for use.The product was not returned for analysis as it was discarded.The lot number was not provided therefore, a product history record (phr) review could not be performed.Based on the limited information provided, it is not possible to draw a clinical conclusion between the device and the reported event.Without a lot number, return of the device or procedural images for analysis, the reported customer event ¿presyncope¿ could not be confirmed, and the exact root cause could not be determined.Vagal reactions may occur while applying pressure to the groin during percutaneous procedures in which arterial or venous access is obtained.Pressure on a large artery can stimulate the vagus nerve, stimulating a parasympathetic response, i.E., bradycardia, hypotension, presyncope, syncope, heart block, asystole, etc.Causing slowing of the heart rate and a drop in blood pressure.Anxiety, pain, and discomfort at the puncture site may also result in a vagal reaction.Early signs include pallor, nausea and/or yawning, which often present with a slowing of the heart rate before a drop in blood pressure.This is a known potential complication with any invasive procedure during which pressure is applied to the groin area.According to the instructions for use (ifu), ¿the performance of these products may be impaired if not properly and cautiously handled during unpacking and preparation.Complications may occur at any time during or after the procedure.¿ based on the information available there is no indication that the event is related to the device design or manufacturing process.Therefore, no preventative or corrective actions will be taken at this time.
