A male infant with tetralogy of Fallot was given a modified left Blalock-Taussig shunt at 11 days of age because of duct dependence. Twenty months later, because of increasing cyanosis and polycythaemia, he was given palliative treatment with balloon dilatation of the right ventricular outflow tract. Seven months later a right ventricular angiogram showed further progression of the infundibular stenosis with poor anterograde opacification of the pulmonary arteries. He underwent percutaneous transcatheter myectomy of the infundibulum with an atherectomy catheter. One month later he was well and less cyanosed.
一名患有法洛四联症的男婴因依赖动脉导管，在11日龄时接受了改良的左布莱洛克-陶西格分流术。20个月后，由于紫绀和红细胞增多症加重，他接受了右心室流出道球囊扩张的姑息治疗。7个月后，右心室血管造影显示漏斗部狭窄进一步进展，肺动脉顺行性显影不佳。他接受了使用旋切导管经皮经导管漏斗部心肌切除术。1个月后，他情况良好，紫绀减轻。
