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)
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)
BACKGROUND Atrioventricular block (AVB) is a well-reported complication after closure of perimembranous ventricular septal defects (VSDs). To report the occurrence of AVB either during or following closure of perimembranous VSDs using a novel "hybrid" method involving a minimal inferior median incision and of intraoperative device closure of the(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)
PURPOSE To evaluate transthoracic minimally invasive device closure of atrial septal defects by performing transthoracic echocardiography to measure changes in cardiac hemodynamics and loading conditions. METHODS Between January 2012 and December 2012, we performed transthoracic minimally invasive device closure of atrial septal defects in 95 patients(More)
OBJECTIVE To discuss the feasibility and experience of treating valvular heart diseases with thoracoscopy-assisted mitral valve replacement concomitant with tricuspid valvuloplasty, with domestically manufactured pipeline products for cardiopulmonary bypass. METHODS A total of 135 patients with valvular heart disease were admitted to our hospital between(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 A hybrid approach to minimally invasive perventricular closure of VSD in infants is safe and effective, and has been performed under guidance of transesophageal echocardiography (TEE). We applied transthoracic echocardiographic (TTE) guidance to this hybrid approach, and compare results guided by TTE with those by TEE. METHODS From January 2011(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)
