CTICasesCollapsed Melody Valve
Imaging findings
A patient with a transcatheter Melody valve in the pulmonary position developed high pressure gradients. Imaging revealed that the valve and stent scaffolding had become disfigured and collapsed over time.
Key takeaways
Transcatheter valves, particularly in the pulmonary position, are subject to external forces that can lead to structural collapse or disfigurement. High gradients in these patients should prompt investigation for mechanical structural failure.
