BACKGROUND Patients with right atrial isomerism (RAI) have several cardiac malformations historically resulting in significant morbidity and mortality. We sought to assess whether current surgical strategies have improved the outcomes of patients with RAI. METHODS A retrospective review of our database from 1997 to 2010 identified 60 consecutive patients(More)
BACKGROUND Although the Fontan procedure is now being performed in younger patients, the influence of the early timing of Fontan on midterm to long-term results remains unclear. We investigated whether the timing of Fontan completion affects subsequent hemodynamics in patients with functional single ventricle followed for more than 3 years. METHODS(More)
OBJECTIVE The purpose of this study is to evaluate the surgical repair of functional single ventricle and extracardiac total anomalous pulmonary venous connection (TAPVC). METHODS Between January 1998 and December 2007, 26 consecutive patients underwent surgical repair of extracardiac TAPVC. Their characteristics were as follows: median age, 34 (range(More)
OBJECTIVE We adopted a policy of rapid-staged bilateral pulmonary artery banding (bPAB) before the Norwood (NW) procedure for all patients with hypoplastic left heart syndrome. We hypothesized that this strategy might mitigate some of the traditional risk factors and that postponing a major bypass procedure beyond the newborn period could have both short-(More)
OBJECTIVES Although pulmonary valve-sparing repair is preferable for patients with tetralogy of Fallot, the repair of very small pulmonary valves is challenging. The present study evaluates our modification for preserving severely hypoplastic pulmonary valves in patients with tetralogy of Fallot. METHODS Sixty-eight consecutive patients who underwent(More)
Primitive neuroectodermal tumor of the sternum is rare. A 59-year-old woman referred to our department with anterior chest pain and a tumor in the sternum. The patient was diagnosed as primitive neuroectodermal tumor of the sternum by core biopsy of the lesion. She received 2 cycles of preoperative chemotherapy with vincristine, doxorubicin,(More)
We report preventive innominate artery division or ligation through a suprasternal approach for impending tracheo-innominate artery fistula (TIF) with recurrent airway oozing in patients with severe neuromuscular disease. Our approach is less invasive and a favorable procedure as preventive surgery for impending TIF.
OBJECTIVE We aimed to evaluate surgical repair of atrioventricular valve regurgitation in patients with functional single ventricle. METHODS The medical records of 65 consecutive patients with functional single ventricle who underwent atrioventricular valve repair between January 1999 and October 2008 were reviewed retrospectively. Their characteristics(More)
OBJECTIVES Bicuspid aortic valve (BAV) is a common risk factor for valve-related problems and occurs more frequently in patients with an interrupted aortic arch (IAA) or coarctation of the aorta (CoA), combined with a ventricular septal defect (VSD), than in the general population. We have been using conventional repair for patients with IAA/CoA+VSD,(More)
Two girls with acute lymphocytic leukemia (ALL) are reported. There were difficulties in removing their central venous catheters inserted from a peripheral vein. One girl required surgery under general anesthesia for the removal. The other patient received continuous infusion of low dose urokinase from a distal peripheral vein. The residual catheter was(More)
