The “MAC” Attack: When Mitral Annular Calcification Goes Rogue! A Case Series of Mobile Mitral Annular Calcifications

“…4 MAC-related CAT constitutes a subgroup of CAT, often associated with end-stage renal disease. 2,5,6 MAC is classically felt to be benign other than causing impedance to transvalvular flow. Interestingly, in a series of 182 patients who had documented arterial thromboembolic events, 10 patients had MAC as the only abnormality identified.…”

A Rare Beast: Cardiac Calcified Amorphous Tumor

“…Although most published cases of CAT to date were treated surgically, conservative management may be preferred in some cases, such as asymptomatic elderly patients. 13 In addition, caution should be used in cases with extensive invasion of the myocardium by the tumor, as wide surgical resection could result in fatal complications. 14 Other imaging modalities (computed tomography, magnetic resonance imaging) may have a role in noninvasive diagnosis of cardiac CAT and thus may help avoid surgery in some patients.…”
