Relative Risk Factors for Cardiac Erosion Following Transcatheter Closure of Atrial Septal Defects: A Case-Control Study.

Background: Transcatheter closure of secundum atrial septal defects (ASD) using the Amplatzer septal occluder is generally safe and effective, but erosion into the pericardial space or aorta has been described. Although the absolute risk of this complication is low, there has been no assessment of relative risk factors.

Methods And Results: All erosions reported to St.

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

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.

Left hemitruncus associated with tetralogy of fallot: fetal diagnosis and postnatal echocardiographic and cardiac computed tomographic confirmation.

Anomalous origin of one pulmonary artery from the aorta, or hemitruncus, is a rare cardiac malformation. We report a case of left hemitruncus (aortic origin of the left pulmonary artery) associated with tetralogy of Fallot diagnosed in utero. To the authors' knowledge, this is the first such case diagnosed by fetal echocardiography to be described in the literature.

Reversed differential cyanosis in the newborn: a clinical finding in the supracardiac total anomalous pulmonary venous connection.

The newborn can experience two types of differential cyanosis (DC). The common type of DC occurs when oxygen saturation in the right hand is greater than in the foot. The second type of DC, reversed differential cyanosis (RDC), occurs when oxygen saturation is lower in the right hand than in the foot.

Single-ventricle palliation for high-risk neonates: the emergence of an alternative hybrid stage I strategy.

Background: Survival after stage I palliation for hypoplastic left heart syndrome or related anomalies remains poor in high-risk neonates. We hypothesized that a less invasive hybrid approach would be beneficial in this patient population.

Methods: The hybrid stage I procedure was performed in the catheterization laboratory.
