Study limitations
The main limitation of this study was that the population was elderly with an average age of 77.0 years. Although the age is similar to those reported in registry data, the results of the study may not be applicable to a younger population, although this procedure is less relevant to them as it is rarely used in such younger patients.It has been shown that the rate of cerebral embolization is 58% in patients undergoing left ventricular ablation, as measured by pre‐ and postmagnetic resonance imaging (MRI).
