● The incidence and etiology of MAC, especially for those at high risk: the elderly, patients with CKD, women, and patients with Barlow’s mitral valve disease
● The critical role of CT imaging to quantify the extent of mitral annular and valvular calcification, and its location in the annulus, leaflets or ventricles.
● Key surgical considerations, including:
