This year marks the 50th anniversary of the first aortic valve prosthesis implanted in the descending aorta on September 11, 1952 by Dr. Charles A. Hufnagel at the Georgetown University Hospital in Washington, D.C. At this time, before the era of the heart-lung machines with extracorporeal circulation, there was no surgical therapy for patients with aortic insufficiency. Hufnagel implanted his plexiglas ball valve prosthesis, providing a significant hemodynamic improvement to the patients and opening the field of cardiac valve replacement.
今年是1952年9月11日查尔斯·A·胡夫纳格尔博士在华盛顿特区乔治敦大学医院首次将主动脉瓣假体植入降主动脉50周年。当时，在体外循环心肺机时代之前，对于主动脉瓣关闭不全的患者没有外科治疗方法。胡夫纳格尔植入了他的有机玻璃球瓣假体，为患者带来了显著的血流动力学改善，并开启了心脏瓣膜置换领域。
