Event Description
|
It was reported that a female patient underwent an ablation procedure for atrial flutter with an ez steer nav ds bi-directional electrophysiology catheter and suffered hypotension requiring computed tomography (ct) and vasopressors.Immediately post-ablation, after successful termination of atrial flutter, the patient became hypotensive.Intracardiac echocardiography (ice) was negative for pericardial effusion.Pulmonary angiography was negative for pulmonary embolism.Abdomen was distended, yet supple.Ct was (b)(6) for retroperitoneal bleeding and pulmonary embolism.Patient was admitted to the intensive care unit (icu) intubated and on vasopressors.Patient required extended (overnight) hospitalization as a result of the adverse event.At the time of complaint update, the patient was being weaned from the ventilator in preparation for extubation.Patient was reported to be in stable condition.Medical history includes a previous surgical repair of an atrial septal defect (asd).Physician¿s opinion regarding the cause of the adverse event is that it was related to a significant decrease in cardiac output secondary to termination of long-term atrial flutter.It was noted that the hemoglobin and hematocrit decreased during the procedure, which may have been related to the 3 liters of volume administered for cardiac output support.

It was reported that a female patient underwent an ablation procedure for atrial flutter with an ez steer¿ nav ds bi-directional electrophysiology catheter and suffered hypotension requiring computed tomography (ct) and vasopressors.The returned device was visually inspected and it was found in normal conditions.The catheter was evaluated for carto 3 functionality and it was recognized by the system, no error messages were displayed and the catheter was properly visualized.Eeprom data demonstrates the catheter was properly calibrated during manufacturing.Then, the catheter was tested for electrical performance and stockert compatibility and it was found within specifications.Additionally, a deflection test was performed and the catheter passed the test.The device history record (dhr) was reviewed and no anomalies were found related to this complaint.In addition, the dhr review verifies that the device was manufactured in accordance with documented specification and procedures.The catheter passed all specifications.The root cause of the adverse event remains unknown.The instructions for use states that careful catheter manipulation must be performed in order to avoid cardiac damage, perforation or tamponade.Manufacturer's ref.No: (b)(4).
