As reported by the field clinical specialist (fcs), during a left transfemoral tavr procedure, the 23mm commander delivery system balloon ruptured during deployment.Per report and before deployment, a balloon aortic valvuloplasty (bav) was performed with a 18mm true balloon.A 23mm sapien 3 ultra valve was implanted in the native aortic annulus with nominal volume.During deployment, the delivery system balloon ruptured once it was inflated due to calcium at the stj (sinotubular junction).There were no issues with the valve.Post deployment, there was no paravalvular leak and post dilation was not performed.The operating team was unable to withdraw the delivery system back into the esheath+.A vascular surgeon was called into the procedure, and a left iliac surgical cut down was performed to remove the esheath+ and commander delivery system as a unit.The iliac artery was then closed and no other issue noted.The commander delivery system is not available for return as it was discarded.Reportedly, the patient is still intubated at postoperative day 1.
