TAVR explant with aortic root replacement using a homograft for an aortic rupture

This case report describes the explantation of an Evolut PRO valve 9 months after implantation in a 69-year-old male presenting with an aortic rupture adjacent to the stent frame of the prosthesis. Imaging was consistent with aortic sinus pseudoaneurysm and a large haemopericardium. Degeneration of the aortic root compounded by the transcatheter prosthesis in addition to the aortic rupture required replacement of the aortic root. The complexity of the procedure also required a modified Cabrol...

Aortic Valve Reconstruction With Autologous Pericardium Versus a Bioprosthesis: The Ozaki Procedure in Perspective

Background We assessed the Ozaki procedure, aortic valve reconstruction using autologous pericardium, with respect to its learning curve, hemodynamic performance, and durability compared with a stented bioprosthesis. Methods and Results From January 2007 to January 2016, 776 patients underwent an Ozaki procedure at Toho University Ohashi Medical Center. Learning curves, aortic regurgitation (AR), and peak gradient, assessed by serial echocardiograms, valve rereplacement, and survival were...
