Previously, cardiac surgeons and cardiologists learned to operate new clinical devices for the first time in the operating room or catheterization laboratory. We describe a biosimulator that recapitulates normal heart valve physiology with associated real-time hemodynamic performance.
To highlight the advantages of this simulation platform, transventricular extruded polytetrafluoroethylene artificial chordae were attached to repair flail or prolapsing mitral valve leaflets. Guidance for key repair steps was by 2-dimensional/3-dimensional echocardiography and simultaneous intracardiac videoscopy.
Multiple surgeons have assessed the use of this biosimulator during artificial chordae implantations. This simulation platform recapitulates normal and pathologic mitral valve function with associated hemodynamic changes. Clinical situations were replicated in the simulator and echocardiography was used for navigation, followed by videoscopic confirmation.
This beating heart biosimulator reproduces prolapsing mitral leaflet pathology. It may be the ideal platform for surgeon and cardiologist training on many transcatheter and beating heart procedures.
此前，心脏外科医生和心脏病学家都是在手术室或导管实验室首次学习操作新的临床设备。我们描述了一种生物模拟器，它可以再现正常的心脏瓣膜生理学，并具有相关的实时血液动力学性能。
为了突出这个模拟平台的优势，经心室挤压的聚四氟乙烯人工腱索被用于修复连枷或脱垂的二尖瓣瓣叶。关键修复步骤的指导是通过二维/三维超声心动图和心内同时录像检查。
多位外科医生已经评估了在人工腱索植入过程中使用这种生物模拟器的情况。该模拟平台再现了正常和病态二尖瓣功能以及相关的血液动力学变化。在模拟器中复制了临床情况，并使用超声心动图进行导航，然后通过录像检查确认。
这个跳动心脏生物模拟器再现了脱垂的二尖瓣瓣叶病变。它可能是用于经导管和跳动心脏手术的外科医生和心脏病学家培训的理想平台。
