Mitral valve surgery can be especially difficult in patients with mitral annular calcification. Not only is it associated with higher morbidity and mortality, but there is no consensus strategy for the treatment of mitral annular calcification, which may render some patients inoperable. We describe a case of severe mitral annular calcification successfully treated with the cavitron ultrasonic surgical aspirator. We demonstrate the proper technique for and the efficacy of using this instrument for decalcification of the mitral annulus. The video tutorial includes the patient presentation, preoperative and postoperative imaging, and the proper surgical technique for cavitron ultrasonic surgical aspirator-assisted mitral annular decalcification. With the proper technique, the cavitron ultrasonic surgical aspirator may mitigate the risk of surgical complications associated with severe calcification of the mitral annulus.
二尖瓣手术在二尖瓣环钙化的患者中可能特别困难。它不仅与更高的发病率和死亡率相关，而且对于二尖瓣环钙化的治疗也没有共识策略，这可能使一些患者无法手术。我们描述了一例使用 Cavitron 超声外科吸引器成功治疗的严重二尖瓣环钙化病例。我们展示了正确的技术，并证明了该仪器在二尖瓣环去钙化中的有效性。该视频教程包括患者介绍、术前和术后影像学以及 Cavitron 超声外科吸引器辅助二尖瓣环去钙化的正确手术技术。通过正确的技术，Cavitron 超声外科吸引器可以降低与严重二尖瓣环钙化相关的手术并发症的风险。
