Event Description

Medtronic received information that during implant of this transcatheter bioprosthetic valve, the valve (b)(6) dislodged unnoticed during subclavian treatment and was snared.Per the physician, it appeared that the guidewire was left in place when the pigtail catheter that had been inserted through the lower leg was removed, or that the guidewire got caught and pulled while stuck.An ascending aorta dissection was suspected, however no dissection was visible on computed tomography (ct) scan.The team decided to implant a second valve (b)(6).Subclavian approach was considered too dangerous, therefore the team switched to right transfemoral approach.The second valve (b)(6) was inserted, but the guidewire appeared to stray into the stent frame and did not pass through.The patient's blood pressure decreased while the wire was being crossed again.Pericardial effusion increased, and was punctured due to cardiac tamponade.When the guidewire was inserted, it entered the false lumen and caused a large dissection.The cardiac tamponade was resolved and the valve (b)(6) was placed.There were no problems with placement: the outflow side did not spread, but the paddles came off.  an 18fr introducer sheath was inserted with no problem in order to place viabahn: one viabahn was placed in the right lower limb and one viabahn was placed in the subclavian artery, near the synthetic vascular junction.  following placement of the second valve, the patient had a complete atrio-ventricular (av) block.No additional adverse patient effects were reported.

Event Description

Additional information was received that clarified previously reported information.Per the physician, the medtronic guidewire got caught and pulled while stuck.The guidewire was stuck because it was left in place after the pigtail catheter had been inserted through the lower leg and was withdrawn.It was further reported that a pre-implant balloon aortic valvuloplasty (bav) was performed.Patient anatomy was not a contributing factor to the dislodgement.The deployment starting point was at the bottom of the pigtail catheter, and the direction of the dislodge was aortic.Prior to valve dislodgement, the implant depth on the non-coronary cusp (ncc) was 3 millimeter¿s (mm) and the implant depth on the left coronary cusp (lcc) was 3 mm.Per the physician, the valve did not cause or contribute to the dissection.Per the physician, the delivery catheter system (dcs) and in-line sheath damaged the subclavian artery because the inline sheath did not pass through the patient¿s anatomy which necessitated for the use of an 18 french sheath.The cause of the dissection was due to smaller vessel diameters.1 day following the implant of the valve, a permanent pacemaker was implanted for complete heart block (chb).No additional adverse patient effects were reported.

Event Description

Additional information was received that during the valve procedure, two dissections occurred with the first delivery catheter system (dcs) used.The location of the dissection's were the subclavian artery and the femoral artery.
