■金星P-valve™(金星医疗技术,杭州,中国)是一种自膨式生物瓣膜,可以经导管植入天然右心室流出道(RVOT)患者。瓣膜植入在技术上具有挑战性。由于植入技术,左肺动脉(LPA)支架是金星P型瓣膜的相对禁忌症。在这个系列中,我们描述了我们在使用LPA支架的患者中植入VenusP型瓣膜的经验,以及使用全息模型来促进程序规划.
■从2023年1月至10月,安排了17名患者进行金星P-瓣膜植入。16/17(94%)患者成功植入。3/16(18.7%)患者接受了LPA支架的VenusP瓣膜植入。所有患者均接受术前CT扫描。CT数据集用于创建三维(3D)全息模型(艺术,米兰,意大利)的整个心脏,这对于使用改进的技术计划瓣膜植入很有用。手术成功率为100%。无手术并发症发生。所有三名患者在出院和随访时都表现出良好的血流动力学和血管造影结果。
■本病例系列强调了在既往有LPA支架的患者中植入金星P型瓣膜的可行性。全息模型的使用促进了这些具有挑战性的解剖学场景中的程序规划。
UNASSIGNED: Venus P-valve™ (Venus Medtech, Hangzhou, China) is a self-expandable bioprosthetic valve that can be transcatheter-implanted in native right ventricular outflow tract (RVOT) patients. Valve implantation is technically challenging. Due to the implantation technique, left pulmonary artery (LPA) stents represent a relative contraindication to Venus P-valve. In this
case series, we describe our experience in implanting Venus P-valve in patients with previous LPA stents and the use of holographic models to facilitate procedural planning.
UNASSIGNED: From January to October 2023, 17 patients were scheduled for Venus P-Valve implantation. 16/17 (94%) patients were successfully implanted. 3/16 (18.7%) patients underwent Venus P-valve implantation with LPA stents. All patients underwent pre-operative CT scan. CT data set were employed to create three-dimensional (3D) holographic models (Artiness, Milan, Italy) of the entire heart, which were useful to plan valve implantation with a modified technique. Procedural success rate was 100%. No procedural complications occurred. All three patients presented good haemodynamic and angiographic results at discharge and follow-up visits.
UNASSIGNED: This
case-series underscores the feasibility of Venus P-valve implantation in patients with previous LPA stents. The use of holographic models facilitated procedural planning in these challenging anatomical scenarios.
