BACKGROUND To simplify extensive primary repair of the thoracic aorta in acute type A aortic dissection, we developed the open triple-branched stent graft placement technique. The early results of this new technique are reported. METHODS AND RESULTS Between June 2008 and November 2009, 30 patients with acute Stanford type A aortic dissection underwent(More)
OBJECTIVE This study sought to prove the safety and feasibility of intraoperative device closure of atrial septal defect (ASD) with transthoracic minimal invasion in the older patients. METHODS From January 2006 to December 2009, 47 patients aged 50 years or more and suffered from atrial septal defect were enrolled in our institution. Patients were(More)
The objective of this study was to investigate whether the α agonist dexmedetomidine has the ability to attenuate hypoxemia in pediatric patients undergoing palliative pulmonary artery reconstruction.From January 2009 to January 2013, a total of 25 pediatric patients with Tetralogy of Fallot, pulmonary atresia (ventricular septal defect), or persistent(More)
BACKGROUND The purpose of this study was to evaluate the safety and feasibility of intraoperative device closure of the doubly committed subarterial ventricular septal defect (VSD). METHODS From January 2009 to January 2010, we enrolled 15 patients with doubly committed subarterial VSD who underwent intraoperative device closure in our institution. Our(More)
OBJECTIVES This study aimed to assess the safety and feasibility of intraoperative device closure of perimembranous ventricular septal defects (VSD) in young children guided by transthoracic echocardiography (TTE). METHODS We enrolled 18 patients from our hospital to participate in the study from June 2011 to September 2011. A minimal inferior median(More)
OBJECTIVES Conventional surgical closure has been considered the gold standard for the treatment of perimembranous ventricular septal defects (PVSDs) in infants for many years, but it requires a cardiopulmonary bypass and midline sternotomy which can lead to both physical and psychological trauma in the future. An intraoperative device closure can be(More)
OBJECTIVES Atrioventricular block (AVB) is a infrequent and serious complication after percutaneous ASD closure. In this study, we report on the incidence of AVB associated with intraoperative device closure of the ASD with transthoracic minimal invasion, and the outcomes of this complication in our center. METHODS Between May 2006 and January 2011, a(More)
BACKGROUND In total arch replacement for patients with acute type A aortic dissection, anastomoses of the graft to the left subclavian artery and descending aorta are often difficult, and the arch vessel anastomosis is frequently performed at the site of dissection. To make this procedure easier and safer, we developed 2 modified techniques: open(More)
BACKGROUND Our purpose was to investigate the feasibility of transthoracic echocardiographic (TTE) guidance for minimally invasive periventricular device closure of perimembranous ventricular septal defects (VSDs). METHODS From June 2011 to September 2011, we enrolled 18 young children with perimembranous VSDs to receive minimally invasive device closure(More)
