No, the heresy was elevating poor Mary to the stature of Goddess because the men of the time couldn't bear the idea of a mere woman being so important.  Heresy was claiming a form of physical resurrection for Mary (or is her body still dead while in heaven?)  Heresy was denying that a woman could have children and still be the chosen mother of Jesus.  Heresies all, and repeated until "sanctified" as tradition.
