Novel Percutaneous Treatment Strategies for Native Right Ventricular Outflow Tract Dysfunction-The Role of Balloon Expandable Valves in Native RVOT Dysfunction

The Role of Balloon Expandable Valves in Native RVOT Dysfunction

Video Transcription

Video Summary

Dr. Shurbana Shahnawaz, director of the Pediatric Cath Lab at Cincinnati Children's Hospital, discussed the role of balloon expandable valves in native VARVIR-T dysfunction. The Medtronic Melody valve was the first mentioned, which has been around for two decades and is approved for valve-in-valve implantations in Europe, Canada, and the United States. It is not approved for aortic and mitral positions or native RVOTs. The speaker discussed a study by Mary Hart Martin, which evaluated the placement of the Melody valve in native RVOT. The study found that patients with more narrowing in the RVOT were more likely to receive the valve. The speaker also talked about the Sapien Next valve, which is used in majority of conduit cases but can be helpful in native RVOTs for perivalvular leakage. The speaker shared real-world data on the use of Sapien valves in native RVOTs, showing that 89% of implants were clinically successful. Complications discussed included artery injury and tricuspid regurgitation. Overall, balloon expandable valves still have a role in native RVOTs.
