Neonates with hypoplastic left heart syndrome (HLHS) and intact atrial septum (IAS) usually present with severe acidosis and hypoxemia that necessitate immediate intervention to create an atrial septal defect (ASD). Transcatheter creation of an ASD in these patients requires transseptal puncture of a thickened atrial septum in the setting of a very small left atrium. We report on a novel method of perforating the atrial septum using radio-frequency energy in combination with a transseptal needle to facilitate transseptal puncture and subsequent stent placement in a very thick atrial septum of a newborn with HLHS/IAS and a small left atrium.
患有左心发育不全综合征（HLHS）且房间隔完整（IAS）的新生儿通常会出现严重酸中毒和低氧血症，这需要立即进行干预以制造房间隔缺损（ASD）。在这些患者中经导管制造ASD需要在非常小的左心房情况下对增厚的房间隔进行经房间隔穿刺。我们报告了一种使用射频能量结合经房间隔穿刺针来穿刺房间隔的新方法，以促进在患有HLHS/IAS且左心房小的新生儿非常厚的房间隔中进行经房间隔穿刺及随后的支架置入。
