This week we delve into the exciting world of congenital interventional cardiology with 2 very different types of interventional cardiology research. In the first highly technical work from the group at Children's Hospital of Michigan in Detroit, we review an innovative approach to transcatheter management of pulmonary regurgitation in tetralogy when the RVOT is just too large for a valved stent. Dr. Tom Forbes, director of the cardiac catheterization laboratory and co-author of this work, discusses the challenges to and indications for bilateral branch pulmonary artery valve implantation in such cases. In the second work, the concept of practice variation and its impact on outcomes is explored by Dr. Andy Glatz and the team from Children's Hospital of Philadelphia reporting data from the IMPACT registry on compliance of interventionalists with established and published guidelines for proceeding with aortic or pulmonary valvuloplasty. Dr. Glatz will join us to discuss some of the interesting aspects of his work as well as trying to answer the question of whether 'homogenizing' our approach to a somewhat 'heterogeneous' group of patients makes good sense.
