Event Description
|
It was reported that during an ablation procedure to treat ventricular tachycardia with an intellamap orion high resolution mapping catheter and a non-boston scientific sheath, the catheter was blinking only during mapping of the right ventricular outflow tract (rvot), and it was not displayed.The intellanav mifi open-irrigated (oi) was able to be displayed.No error message displayed.Each power was rebooted, but the issue was not resolved, and the procedure was continued as it was.Prior to abating, after about 30 seconds of mapping, a cardiac tamponade was noted near the patient's rvot.A pericardial drainage was performed and the procedure was completed with stable blood pressure.The patient had no further issues.No resistance was felt during manipulating the catheter.It was unknown what caused the cardiac tamponade, but it was reported that it was a possibility that the sheath was pressed to the wall of the heart chamber too hard when it was advanced to rvot.There were no visible issues or damage with the intellamap orion high resolution mapping catheter.No electrical interference was seen on the orion.The device has been received and is pending analysis.
