Catalog Number D134801

Device Problem Patient Device Interaction Problem (4001)

Patient Problem Ischemic Heart Disease (2493)

Event Date 11/27/2023

Event Type  Injury  

Event Description

It was reported that a patient underwent a cardiac ablation procedure for premature ventricular contraction, with a thermocool® smart touch® sf bi-directional navigation catheter, and patient experienced an elevated st segment requiring surgical intervention.The elevated st segment occurred when ablated for summit vpc (premature ventricular contraction) after ablation was conducted in cs (coronary sinus).Emergency pci (percutaneous coronary intervention) with stenting with balloons was performed based on the diagnosis of lcx (left circumflex artery) occlusion.Patient outcome was improved.Lcx flow was recovered and maintained.Patient was followed up in hospital for pericarditis and will be discharged soon.The physician's opinion on the relationship between the event and the product was that the heat from ablating in the cs might have added to the lcx.The ablation was stopped several times due to the impedance monitoring, and the device was working as normal during the operation.There were no abnormalities observed before or while using the product.
