Huge mitral annular calcification discovered after a TIA prompts conservative medical monitoring.
Case Report (n=1)
This case highlights that a large mitral annular calcification can serve as a source of embolic stroke even in the absence of traditional cardiovascular risk factors.
Large mitral annular calcification may be an embolic source for stroke without traditional risks; hypothesis-generating and should not yet change practice.
Case ReportBackground: Mitral annular calcification (MAC) is a degenerative process which commonly occurs in the elderly.Patients with MAC have a higher prevalence of left atrial enlargement, left ventricular enlargement, atrial fibrillation, conduction defects, mitral regurgitation, and mitral stenosis.In addition, these patients have a higher incidence of cardiovascular events, thromboembolic events.Case Presentation: A 75-year-old Moroccan woman with no cardiovascular risk factors presented a transitory ischemic stroke.A transthoracic echocardiogram revealed a mitral annular mass (21 × 12 mm) attached to the auricular side of the posterior mitral valve leaflet.The cerebral CT scan showed lesions of a previous embolic stroke.The cardiac CT-Scan and a cardiac MRI confirmed the diagnosis of a mitral annular calcification.Conclusions: In the present case, the mitral annular calcification did not require any treatment.Instead, patients are managed according to the presence of heart block, mitral regurgitation and other cardiovascular signs and symptoms.

Lamiae et al. (2020) conducted a case report in Mitral annular calcification and embolic stroke (n=1). Mitral annular calcification was evaluated. A 75-year-old woman presenting with a transitory ischemic stroke was found to have a huge mitral annular calcification, which was managed conservatively with medical monitoring.
