Conclusions
MAD could be associated to LV morphological and functional remodeling, which could be the substrate of ventricular arrhythmias and sudden cardiac death. MAD itself should be considered as an arrhythmogenic entity, irrespective of the presence of MR or MVP, and implantation of an ICD, as for our patient, can be life saving.
In conclusion, we can not consider MAD as a well-known entity and more research and further studies are warranted.
