Clinical and hemodynamic performance of the freestyle aortic root bioprosthesis

Surgical Experience of Full Root Replacement with Freestyle Bioprosthesis: Indications, Surgical Technique, and Results

“…12,15 The excellent postoperative hemodynamic performance demonstrated by the stentless bioprosthesis in this study corresponded with the results of other studies. [2][3][4][5][6][7][8][9][10][11][12] There are three different types of implantation technique of stentless bioprosthesis, such as full root replacement, root inclusion technique, and subcoronary technique. The subcoronary technique is most frequently used probably because of the possibility of the development of aortic wall calcification that would make any subsequent reoperation complicated.…”

“…[1][2][3][4][5][6][7][8][9][10][11] Although a modified subcoronary technique has been mainly used as the surgical technique for valve implantation in this procedure, [2][3][4] we have performed full root replacement using a freestyle aortic root bioprosthesis (Medtronic, Minneapolis, MN, USA), especially in elderly patients with severe aortic stenosis. 12 This approach allowed us to replace valves with a larger orifice and also to maintain the integrity of the aortic root leading to a lesser gradient across the aortic valve, thus resulting in a lower risk of postoperative aortic regurgitation (AR).…”

Surgical Management of the Aortic Root

“…This graft allows similar flow and velocity measurements in addition to peri-operative morbidity and mortality to synthetic grafts. [90] In a prospective, randomized trial comparing homografts to Freestyle grafts, long-term survival was found to be the same for the groups. The main indication for root replacement was aortic valve disease associated with pathologic changes in the root.…”

The Quebec Heart Institute: 50 years of excellence in cardiology

“…Nevertheless, all congenital heart surgeries continued to be performed at the Institute. Despite the increased clinical workload, this was the period of innovation and landmark studies on cardiac valve surgery and echocardiographic assessments (13)(14)(15)(16)(17), highlighting the value and limitations of valve replacements, tissue valves, mechanical valves and prosthetic valve mismatches (18)(19)(20)(21). During this period, the Ross procedure was adopted at the Institute, and subsequently the Institute became a pioneer of this surgical procedure in Canada (22,23).…”
