It was reported that a (b)(6) year old (b)(6) patient underwent an ablation procedure for left ventricular premature ventricular contractions (pvcs) with a thermocool smarttouch bi-directional navigation catheter and suffered a vascular dissection (type b aortic dissection) requiring imaging and acute kidney failure requiring no medical or surgical intervention.After ablating some of the pvc sites, the catheter slipped back through the aortic valve.This required maneuvering the catheter back through the aortic arch, across the aortic valve, and re-positioning in the left ventricle.Approximately 30 minutes into the procedure, the patient reported pain radiating from her back to her chest.Physician carefully withdrew the catheter back into the aortic arch.Transthoracic echocardiogram revealed no cardiac abnormalities.While the catheter was in the aortic arch, the patient reported increased pain.Patient was normotensive.Catheter was withdrawn.Aortic arch angiogram revealed some flow abnormalities, but was difficult to assess.Remainder of procedure was aborted.Computed tomography (ct) revealed a type b aortic dissection.Patient was transferred to the intensive care unit for observation.Patient required extended hospitalization as a result of this adverse event for observation and follow-up ct scans to determine the need for intervention.It was noted that the patient had some renal dysfunction.Patient outcome was reported to be unchanged at the time of complaint report.There was no product malfunction reported.Physician did not provide a causality opinion.Since this adverse event might result in permanent impairment of a body function or permanent damage to a body structure, it is to be considered serious and mdr reportable.
