    PER THE INSTRUCTIONS FOR USE, CONDUCTION SYSTEM INJURIES (HEART BLOCK) WHICH MAY REQUIRE A PERMANENT PACEMAKER ARE POTENTIAL ADVERSE EVENTS ASSOCIATED WITH BALLOON AORTIC VALVULOPLASTY, DEPLOYMENT OF THE PROSTHETIC VALVE, AND THE OVERALL TAVR PROCEDURE. ACCORDING TO THE VALVE ACADEMIC RESEARCH CONSORTIUM (VARC) GUIDELINES, THE CLOSE ANATOMICAL RELATIONSHIP BETWEEN THE AORTIC VALVE COMPLEX AND THE BRANCHING ATRIOVENTRICULAR BUNDLE MAY PROVIDE AN EXPLANATION FOR THESE COMPLICATIONS OF THE TAVR PROCEDURE. ACCORDING TO LITERATURE REVIEW, AND AS DOCUMENTED IN A TECHNICAL SUMMARY WRITTEN BY EDWARDS LIFESCIENCES, ATRIOVENTRICULAR CONDUCTION DISTURBANCES AFTER TAVR ARE ASSOCIATED WITH MANY PATIENT RELATED AND PROCEDURAL RELATED FACTORS, INCLUDING PRE-OPERATIVE CO-MORBID STATUS, THE DEGREE AND BULKINESS OF AORTIC VALVE AND ANNULAR CALCIFICATION, INTER-VENTRICULAR SEPTAL THICKNESS, PRE-EXISTING ELECTROCARDIOGRAM ABNORMALITIES, THE DEPTH OF PROSTHESIS IMPLANTATION, AND THE PROFILE OF THE IMPLANTED PROSTHESIS. UNLIKE CONVENTIONAL AVR, WHERE THERE MAY BE LOCALIZED TRAUMA DUE TO DECALCIFICATION OF THE ANNULUS AND/OR SUTURE PLACEMENT IN THE PROXIMITY OF THE AV NODE OR THE BUNDLES, TAVR MAY CAUSE CONDUCTION ABNORMALITIES THROUGH MECHANICAL IMPINGEMENT OF THE CONDUCTION SYSTEM BY THE PROSTHESIS. THE MECHANISMS OF THE DEVELOPMENT OF HEART BLOCK AFTER TAVR ARE WELL DOCUMENTED AND DESCRIBED IN THE LITERATURE. IT IS ALSO DOCUMENTED THAT PRE-EXISTING HEART BLOCK IS COMMON IN PATIENTS UNDERGOING TAVR OR SURGICAL AVR AND ANOTHER 4-6 % WILL DEVELOP POSTOPERATIVE HEART BLOCK, POTENTIALLY REQUIRING A PERMANENT PACEMAKER. IN THIS CASE, THE CAUSE OF THE BRADYCARDIA AFTER THE IMPLANTATION OF A SAPIEN XT VALVE CANNOT BE CONFIRMED. IT IS POSSIBLE THAT PATIENT FACTORS ((B)(6) FEMALE WITH A BASELINE OF 1ST DEGREE HEART BLOCK AT BASELINE) IN COMBINATION WITH PROCEDURAL FACTORS MAY HAVE CAUSED OR CONTRIBUTED TO THE EVENT AS EXPLAINED IN THE TECHNICAL SUMMARY MENTIONED ABOVE. THERE WAS NO ALLEGATION OR INDICATION OF A DEVICE MALFUNCTION. THE IFU AND TRAINING MANUALS HAVE BEEN REVIEWED AND NO INADEQUACIES HAVE BEEN IDENTIFIED WITH REGARDS TO WARNINGS, CONTRAINDICATIONS, AND THE DIRECTIONS/CONDITIONS FOR THE SUCCESSFUL USE OF THE DEVICE. COMPLAINT HISTORIES FOR ALL REPORTED EVENTS ARE REVIEWED AGAINST TRENDING CONTROL LIMITS ON A MONTHLY BASIS, AND ANY EXCURSIONS ABOVE THE CONTROL LIMITS ARE ASSESSED AND DOCUMENTED AS PART OF THIS MONTHLY REVIEW. NO CORRECTIVE OR PREVENTATIVE ACTIONS ARE REQUIRED AT THIS TIME.

    Description of Event or Problem · 1

    POST DEPLOYMENT OF THE 23MM SAPIEN XT VALVE, PLACED 50:50, THE PATIENT HAD A COMPLETE HEART BLOCK WHICH RESOLVED AND BY THE END OF THE CASE THE PATIENT WAS IN SINUS RHYTHM. THE TEMPORARY PACEMAKER WAS LEFT ON, BUT THE NEXT DAY SHE WAS BRADYCARDIC WITH HEART RATE IN THE 40¿S. A PERMANENT PACEMAKER (PPM) WAS IMPLANTED. THE PATIENT WAS DISCHARGED IN STABLE CONDITION. THE PATIENT¿S BASELINE RHYTHM WAS 1ST DEGREE HEART BLOCK; THE AORTIC ANNULUS DIAMETER MEASURED 21MM (349MM2) WITH MODERATE CALCIFICATION EXTENDING DOWN THE MITRAL.
