Endocarditis is a devastating complication of prosthetic aortic valve replacement. The infective process can destroy aortic annulus tissue, making conventional surgical valve replacement difficult or impossible and causing aortoventricular discontinuity. Several treatment techniques have been proposed. One of these, the Danielson technique, involves translocating the aortic valve to the native ascending aorta, débriding the abscess cavity, closing the coronary ostia, and bypassing the coronary arteries with a Y anastomosis between 2 vein grafts. We describe our use of a modified Danielson technique in a 68-year-old man with advanced prosthetic valve endocarditis that was associated with aortic annulus destruction and aortoventricular discontinuity. This modified technique enables safer, more secure anchoring of a replacement valve, reduces the risks and concerns associated with bypass grafts, and successfully treats aortoventricular discontinuity.

心内膜炎是人工主动脉瓣置换术的一种破坏性并发症。感染过程会破坏主动脉瓣环组织，使传统的外科瓣膜置换变得困难或不可能，并导致主动脉室间断。已经提出了几种处理技术。其中之一，丹尼尔森技术，涉及将主动脉瓣转移到天然升主动脉，清创脓肿腔，关闭冠状动脉口，并在两个静脉移植物之间通过 Y 型吻合术绕过冠状动脉。我们描述了我们在一名 68 岁男性患有与主动脉瓣环破坏和主动脉室间断相关的晚期人工瓣膜心内膜炎中使用改良的 Danielson 技术。这种改进的技术可以更安全、更牢固地锚定置换瓣膜，
