An 81-year-old man with high-grade aortic valve stenosis and status post-coronary artery bypass grafting and supracoronary replacement of the ascending aorta was referred for transcatheter aortic valve implantation. He was in New York Heart Association class III and had dyspnea. After appropriate screening, we implanted a 29-mm SAPIEN XT valve (Edwards Lifesciences, Irvine, CA USA) through a transapical approach because of severe peripheral arterial occlusive disease. Postinterventional aortography revealed correct positioning and function of the valve and free coronary ostia but contrast extravasation in the vicinity of the interposed vascular prosthesis, resulting in severe luminal narrowing. We chose to manage the stenosis with an endovascular stent. After stenting, extravascular compression was markedly reduced, and the pressure gradient disappeared. The patient was discharged home on the 20th postoperative day. Three months later, computed tomography depicted correct positioning of both grafts. The patient's general health is good, and he is now in New York Heart Association class II. This case illustrates a complication of transcatheter aortic valve implantation specific for patients with an ascending aortic graft. Although stenting may be a good solution, as depicted by this case, self-expanding transcatheter aortic valves should be preferred in patients with ascending aortic grafts to avoid the described complication.
一名81岁男性,患有重度主动脉瓣狭窄,曾接受冠状动脉旁路移植术及升主动脉冠状动脉上置换术,因行经导管主动脉瓣植入术前来就诊。他处于纽约心脏协会心功能Ⅲ级,有呼吸困难症状。经过适当筛查后,由于严重的外周动脉闭塞性疾病,我们通过经心尖途径植入了一枚29毫米的SAPIEN XT瓣膜(美国加利福尼亚州尔湾市爱德华兹生命科学公司)。介入术后主动脉造影显示瓣膜位置正确、功能正常且冠状动脉开口通畅,但在置入的血管假体附近有造影剂外渗,导致管腔严重狭窄。我们选择使用血管内支架来处理该狭窄。支架置入后,血管外压迫明显减轻,压力梯度消失。患者术后第20天出院回家。三个月后,计算机断层扫描显示两个移植物位置正确。患者总体健康状况良好,目前处于纽约心脏协会心功能Ⅱ级。该病例说明了经导管主动脉瓣植入术针对升主动脉移植物患者的一种并发症。尽管如本病例所示,支架置入可能是一个好的解决方案,但对于有升主动脉移植物的患者,应优先选择自膨胀式经导管主动脉瓣,以避免所述并发症。
