Echocardiographic Finding of Non-Obstructive Fibromuscular Band in Right Atrium

Cortriatrium was first time was seen in 1868.It is a congenital anomaly in which the left atrium or right atrium is divided into two chambers by a fold of tissue, a membrane or a fibro muscular band., The upper part of the corresponding atrium receives venous blood, whereas the lower portion is in contact with the atrioventricular valve The membrane that separates the atrium into two parts may be a complete imperforated band or may have one or more holes for blood to pass [11][12][13][14][15][16][17][18][19][20]. Cortriatriatum sinister is a congenital heart defect characterised by a fibro muscular membrane in left atrium.…”
