It was reported that a (b)(6) female patient underwent a pulmonary vein isolation (pvi) ablation procedure for atrial fibrillation with a pentaray nav eco catheter and suffered a suspected air embolism requiring medication for blood pressure support, sonography, and angiography.Transseptal puncture was performed.Pentaray nav eco catheter was flushed and inserted into the left atrium.As mapping was about to be initiated, the patient became severely hypotensive and bradycardic.Patient was stabilized with medication for blood pressure support.Sonography and coronary angiography were performed and did not provide confirmation of air embolism.Patient was noted to be in atrial fibrillation.After stabilization, mapping and pvi were performed.Atrial fibrillation was successfully terminated.Patient did not require extended hospitalization as a result of the adverse event.Patient fully recovered with no residual effects.Procedure was prolonged by 20 minutes.Physician did not attribute the event to a bwi product, but to transseptal puncture.The medical rationale that indicates that the bwi product was in no way related to the adverse event is that air was introduced into the left atrium during transseptal puncture.Physician¿s opinion regarding the cause of the adverse event is that it was related to procedure, specifically transseptal puncture.However, this complaint is being conservatively reported because the patients symptoms occurred after insertion of this catheter into the body and no air embolism was ever confirmed.
