Transaortic transcatheter aortic valve replacement performed through a right anterolateral minithoracotomy at the second intercostal space is a safe and standardized minimally invasive procedure carrying important clinical advantages for the patient, in particular, no damage to the ventricular apex, preservation of the diseased peripheral arteries and no cross of the aortic arch with the delivery system, meaning a lower risk of calcium dislodgement and neurological complications. Using the third-generation, balloon-expandable Edwards Sapien™ 3 transcatheter heart valve and the Certitude™ delivery system, the transaortic procedure is easily performed under fluoroscopic and echocardiographic guidance. Compared with the transapical procedure, the transaortic technique requires an inversely mounted stent valve and follows the standard guidelines for valve positioning and deployment under rapid pacing. The transaortic approach through a right anterolateral minithoracotomy at the second intercostal space combines the positive aspects of both transfemoral and transapical valve replacements without the risks of either procedure (left ventricular, coronary and peripheral vascular injuries).
经右前外侧第二肋间小切口进行经主动脉瓣的经导管主动脉瓣置换术是一种安全且标准化的微创手术,对患者具有重要的临床优势,特别是不会损伤心尖,保留病变的外周动脉,且输送系统不穿过主动脉弓,这意味着钙移位和神经并发症的风险较低。使用第三代球囊扩张式爱德华兹Sapien™ 3经导管心脏瓣膜和Certitude™输送系统,经主动脉手术可在荧光镜和超声心动图引导下轻松完成。与经心尖手术相比,经主动脉技术需要倒置安装的支架瓣膜,并遵循快速起搏下瓣膜定位和展开的标准指南。经右前外侧第二肋间小切口的经主动脉入路结合了经股动脉和经心尖瓣膜置换的积极方面,而没有这两种手术(左心室、冠状动脉和外周血管损伤)的风险。
