Edge-to-edge repair of the systolic anterior motion of mitral valve and cardiac myectomy of the abnormally positioned papillary muscles in an infant with COL4A1 mutation
Abstract:Surgical treatment is challenging in pediatric patients with left ventricular outflow tract (LVOT) stenosis (LVOTS). We herein present the case of a 2-year-old male patient with porencephaly who was diagnosed with LVOTS accompanied by moderate mitral valve regurgitation (MR) with systolic anterior motion (SAM). Edge-to-edge mitral valve reconstruction and myectomy of the abnormal cardiac muscle were performed, with an uneventful postoperative course. LVOT myectomy and edge-to-edge mitral valve repair may be co… Show more
