摘要

In their article, Edwards et al. present the successful catheterization of all four cardiac chambers in a mid-gestation sheep model using percutaneous transhepatic access into the hepatic vein. Access to the heart could be gained in 8/10 cases, all four chambers could be reached in four cases and two fetuses died during the procedure.The investigation of novel access routes to the fetal heart is of the utmost importance for the development of new treatment modalities. Up to now, fetal cardiac intervention for valvuloplasty or atrial septoplasty/stent insertion has involved a percutaneous transventricular or transatrial approach, techniques that are prone to brady-cardia, injury of the conductive system, hemodynamic compromise, cardiac tamponade and fetal death.
