A 5-hour-old boy underwent arterial switch operation and totally anomalous pulmonary venous connection repair. Subsequently developed severe pulmonary venous stenosis was successfully treated with hybrid balloon angioplasty.
A 26-year-old woman underwent tetralogy of Fallot repair and classic Blalock-Taussig shunt (BTS) ligation. On postoperative day 4 she developed severe left-sided hemiplegia due to cerebral infarction. Thrombi in the BTS stump, right brachiocephalic artery, and its branches were removed surgically and the BTS stump was resected. The patient gradually(More)
OBJECTIVES This article reports the safety and efficacy of a morphology-based algorithm for the surgical management of pulmonary atresia and ventricular septal defect with major aortopulmonary collateral arteries. METHODS A total of 83 patients were operated from 2007 to 2014 using 3 surgical approaches: one-stage total repair, one-stage unifocalization(More)
BACKGROUND This study evaluates the hemoglobin-oxygen relationship and tissue perfusion during cardiopulmonary bypass (CPB) in neonates undergoing open-heart surgery using autologous umbilical cord blood or donor blood components. METHODS We compared perioperative hematocrit (Hct), fetal hemoglobin (HbF), p(50)O(2), pH, pCO(2), serum lactate, duration of(More)
Origin of the circumflex coronary artery (Cx) from the pulmonary arteries is an extremely rare anomaly. We describe a two-month-old female patient with anomalous origin of the Cx from the right pulmonary artery associated with coarctation of the aorta. Reimplantation of the anomalous Cx to the aorta and coarctation repair were performed. There were no(More)
A neonate with antenatally diagnosed severe aortic valve stenosis, left ventricular outflow tract obstruction, left ventricular endocardial fibroelastosis, and severe mixed mitral valve disease was admitted to our center for balloon aortic valvuloplasty. On day 49, we performed a Ross-Konno procedure and mitral valve replacement on the baby, whose weight(More)
We assessed morbidity after 2 management strategies for arterial switch operation (ASO) in a single institution: first hours of life surgery and conventional approach. From September 2009 to September 2014, 346 consecutive patients who underwent ASO were enrolled. The study group included 92 patients who underwent ASO in the first 24 hours after birth(More)
