title: Atrial septal hematoma after mitral valve and left coronary artery surgery in a child.
abstract: 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.
