Semi-mobile rudimentary tissues attached to a congenital intramitral ring ina woman with previous history of embolic stroke: A rare case report

摘要

Isolated congenital mitral ring is a very rare subtype of congenital mitral valvemalformation, which accounts for about one-third of congenital cardiac anomaliesassociated with left ventricular inflow obstruction. A mitral ring may be easily missedunless the disease is suspected. The mitral valve repair should be considered insymptomatic patients with mitral stenosis. We report a rare case of a 43-year-old womanwith an intramitral ring who experienced previous embolic stroke with left hemiplegia.However, stroke happened several years ago and it does not completely prove causality.
