HIFU Minimaze

High Intensity Focused Ultrasound (HIFU) can be used to heat tissue epicardially, on the beating heart, to perform the HIFU minimaze procedure. A multicenter trial was published in 2005 (Ninet 2005) show that this could be performed safely and effectively. More recent studies (McCarthy 2010) have show it to be less effective, and the role of this technology is still being explored.
