Patients undergoing right ventricular outflow tract reconstruction are subject to valve and cusp degeneration later in life, requiring further intervention to alleviate the pulmonary regurgitation that ensues. In these cases, percutaneous pulmonary valve implantation can be an effective alternative to surgery; however, since the indications have been limited to dysfunctional valved conduits, only a small number of patients have access to this treatment option. We present the case of an 18-year-old male with a patch-enlarged right ventricle to pulmonary artery conduit who underwent pulmonary valve implantation using two Melody transcatheter pulmonary valves (Medtronic, Inc) into the proximal right and left branch pulmonary arteries.
接受右心室流出道重建的患者在晚年易出现瓣膜和瓣叶退化,需要进一步干预以缓解随之而来的肺动脉反流。在这些情况下,经皮肺动脉瓣植入术可成为手术的有效替代方案;然而,由于适应症仅限于功能失调的带瓣管道,只有少数患者能够获得这种治疗选择。我们报告一例18岁男性患者,其右心室至肺动脉管道采用补片扩大,使用两枚美敦力公司的Melody经导管肺动脉瓣分别植入左右肺动脉近端,进行了肺动脉瓣植入术。
