Percutaneous perforation of pulmonary valve, using 0.014" guidewires meant for coronary artery chronic total occlusion (CTO), is increasingly being performed for select cases of pulmonary atresia with intact ventricular septum (PA-IVS). Despite growing experience, procedural failures and complications are not uncommon. Even in infants treated successfully, the orifice created in the atretic pulmonary valve is eccentric. In this report, we present usefulness of coronary microcatheter in alignment of perforating coronary guidewire to the center of atretic pulmonary valve resulting in central perforation.
使用用于冠状动脉慢性完全闭塞（CTO）的0.014英寸导丝经皮穿刺肺动脉瓣，在越来越多的室间隔完整的肺动脉闭锁（PA-IVS）特定病例中得到应用。尽管经验不断积累，但手术失败和并发症并不罕见。即使在成功治疗的婴儿中，闭锁肺动脉瓣上形成的孔也是偏心的。在本报告中，我们展示了冠状动脉微导管在将冠状动脉穿刺导丝对准闭锁肺动脉瓣中心以实现中心穿孔方面的作用。
