Atrial septal hematoma (ASH) has been reported mostly in adult patients to occur after spontaneous ascending aortic dissection (Circulation 46(3):537–545, 1972) and after surgery for coronary artery (Anesthesiology 83(3):620–621, 1995), mitral valve, and aortic valve (Rev Esp Cardiol 55(8):867–871, 2002). ASH in the pediatric age group is rare, and to our knowledge only two cases have been published (Am J Perinatol 27(6):481–483, 2010; J Am Soc Echocardiogr 1087–1089, 1998). We report a case of ASH diagnosed by intraoperative transesophageal echocardiography in a 28-month-old child who underwent mitral valvuloplasty and left main coronary arterioplasty for anomalous origin of the left coronary artery from pulmonary artery. ASH subsided on its own within 24 h.
