This is one of two manufacturer reports being submitted for this case.Please reference related manufacturer report no: 2015691-2018-02629.Per the instructions for use (ifu) cardiovascular injury, such as perforation dissection of vessels, ventricle, myocardium or valvular structures, is a known potential complication associated with the tavr procedure.According to the thv training manuals, risk factors for aortic dissection, hematoma or annular rupture during the tavr procedure include significant thv over sizing, severely obliterated sinuses of valsalva, porcelain aorta and/or presence of bulky calcification and narrow calcified stj. in addition, advanced age, female gender, small body weight, and steroid dependency can also be contributing factors.The sapien valve relies on native valve calcium to securely anchor to the annulus.Despite this beneficial aspect of calcium, bulky calcium can increase the risk of calcific nodule displacement into the vasculature, which can lead to vascular injury.At times the extent and distribution of calcium can impair ease of delivery of the valve, correct positioning of the valve, deployment of the valve and procedural success.In this case, there was no allegation or indication a device malfunction contributed to this adverse event. investigation results suggest the cause of the aortic rupture was related to the patient¿s porcelain aorta.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.

As reported by our affiliates in (b)(6), during the 29 mm sapien 3 case by tf approach in aortic position, the patient had a porcelain aorta.Crimping was uneventful.The valve was inserted through the sheath with usual push force and valve alignment was performed without issues.After the valve was positioned in the annulus, deployment started.However, only the distal part of the balloon inflated.Due to this the valve moved aortic and was conically deployed.It was decided to pull the valve into the descending aorta and deploy it there.Then a second system was prepared and the valve was successfully deployed.Sometime later it was noticed that the valve that was placed in the descending aorta caused an aortic rupture.Patient was put on extracorporeal membrane oxygenation (ecmo) and it was intended to repair the rupture; however, they were not successful and the patient deceased.The doctor believes the porcelain aorta is the reason for the aortic rupture.
