Most efforts have been made to optimize the size by changing the original design for intra-annular implantation toward placement of the valve in a supra-annular position. The SJM Regent valve (St Jude Medical, Inc) is such a modification and is redesigned for supra-annular implantation by ...
ST.JudeRegent机械瓣膜 在小主动脉瓣环患者中的应用 中文摘要 目的:探讨小主动脉瓣环(直径≤19m)患者行St.JudeMedical Regent(SJMRegent)瓣膜置换术后的心功能改变,研究是否存在植入 瓣膜与患者不匹配(Prosthesis—PatientMismatch,PPM)现象“1,以 及是否有行主动脉瓣瓣环扩大术的必要。
结论(1)19mm St.Jude Regent瓣与21mm其它进口双叶机械瓣有相同的有效瓣口面积和血流动力学效果;(2)在二尖瓣,主动脉瓣双瓣膜置换术中,当主动脉瓣瓣环径偏小时应用19mm St.Jude Regent瓣是比较安全的,不会增加术后早期的心脏事件,不会发生术后早期的PPM;(3)对于PPM的标准,应进一步扩大病例数量,延长随访时间,...

JUDE MEDICAL® cardiac valves have been placed in 43 children. Nine patients were less than 1 year of age and 1 child had a double valve replacement. Twenty-four valves were placed in the aortic position. Seven of these patients underwent valve replacement only, while 16 patients had ...
Between 2000 and 2011, 127 consecutive patients (mean age 79years; 87% female) underwent AVR for aortic valve stenosis with a small aortic annulus. 19-mm BV ( n =67) was implanted. When the 19-mm BV did not fit the annulus, 17-mm St. Jude Medical Regent prosthetic mechanical valve ...
