Severe left ventricular outflow tract obstruction with mitral regurgitation caused by accessory mitral valve tissue in an adult: A case report
Accessory mitral valve tissue (AMVT) is an extremely rare congenital cardiac abnormality in adults. Patients typically present with symptoms and signs of left ventricular (LV) outflow tract (LVOT) obstruction. LVOT obstruction caused by AMTV was diagnosed mostly in the first decade of life. However, isolated cases of AMVT with LVOT obstruction in adulthood are uncommon (1, 2). This paper reports a case of an adult patient aged 56 years with severe LVOT obstruction and severe mitral regurgitation (MR) caused by AMVT.
