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.
