Efficacy, safety, and long-term survival of concomitant valve replacement and bipolar radiofrequency ablation in patients aged 70 years and older: a comparative study with propensity score matching from a single-Centre.

Background: Concomitant bipolar radiofrequency ablation and valve replacement in the elderly remains controversial. In the current study, we aimed to compare the outcomes of concomitant valve replacement and bipolar radiofrequency ablation with valve replacement alone in elderly patients with atrial fibrillation (AF).

Methods: This was a retrospective study of patients aged ≥70 years who underwent valve replacement with or without bipolar radiofrequency ablation in a single-centre between January 2006 and March 2015.

A clinical study of thoracoscopy-assisted mitral valve replacement concomitant with tricuspid valvuloplasty, with domestically manufactured pipeline products for cardiopulmonary bypass.

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 January 2011 and January 2013. They received thoracoscopy-assisted mitral valve replacement concomitant with tricuspid valvuloplasty, with domestically manufactured pipeline products.

Total arch repair for acute type A aortic dissection with open placement of a modified triple-branched stent graft and the arch open technique.

Background: In total arch repair with open placement of a triple-branched stent graft for acute type A aortic dissection, the diameters of the native arch vessels and the distances between 2 neighboring arch vessels did not always match the available sizes of the triple-branched stent grafts, and insertion of the triple-branched stent graft through the distal ascending aortic incision was not easy in some cases. To reduce those two problems, we modified the triple-branched stent graft and developed the arch open technique.

Methods And Results: Total arch repair with open placement of a modified triple-branched stent graft and the arch open technique was performed in 25 consecutive patients with acute type A aortic dissection.

[Non-invasive ventilation in the treatment of infants with respiratory failure after cardiopulmonary bypass].

Objective: To evaluate the effects of non-invasive ventilation in the treatment of infants with respiratory failure after cardiopulmonary bypass (CPB) and extubation.

Method: Sixty-three infants who had undergone successful surgery with CPB, got respiratory failure after extubation. These infants were randomly divided into two groups: non-invasive (NV) group, treated with non-invasive ventilation and invasive (IV) group, treated with tracheal intubation.

Balloon valvuloplasty through the right ventricle: another treatment of pulmonary atresia with intact ventricular septum.

Background: This was a study to evaluate the safety and feasibility of balloon valvuloplasty of the pulmonary valve through the right ventricle (RV) for the treatment of pulmonary atresia with intact ventricular septum (PA-IVS).

Methods: Ten neonates with PA-IVS, who underwent balloon valvuloplasty of the pulmonary valve through the RV at our institution from January 2008 to May 2010, were enrolled in this study. The oxygen saturation range was 60% to 83% (median 76%).

Atrioventricular block subsequent to intraoperative device closure atrial septal defect with transthoracic minimal invasion; a rare and serious complication.

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 total of 213 secundum-type ASD patients were accepted in our hospital for intraoperative and transthoracic device closure with a domestic occluder.

A modified valve-sparing aortic root replacement technique for acute type A aortic dissection: the patch neointima technique.

We describe a modified valve-sparing aortic root replacement technique for acute type A aortic dissection. After the normal root geometry was restored by removing blood and clots in the proximal false lumen and the valve insufficiency was corrected by simple resuspension of the aortic commissures, three teardrop-shaped patches were sutured inside the sinuses as neointima and then in situ coronary buttons were connected to the small holes created in the corresponding patches. Our initial application showed that this modified valve-sparing aortic root replacement technique is an easy and effective way to restore the geometry of the aortic root and avoid bleeding during surgery for acute type A dissection.

Closure of perimembranous ventricular septal defects with intraoperative device technique: another safe alternative to surgical repair.

Objectives: This study aims at assessing the safety and feasibility of intraoperative device closure of the perimembranous ventricular septal defect (VSD).

Methods: Total 89 patients in group I with intraoperative device closure and 58 in group II with surgical repair were enrolled in our hospital to participate in the study from January 2009 to December 2010. In group I, the approach involved a minimal inferior median incision that was performed after full evaluation of the perimembranous VSD by real-time transesophageal echocardiographic guidance, and the insertion of an asymmetric or a symmetric domestically made device was used to occlude the perimembranous VSD.

Atrioventricular block of intraoperative device closure perimembranous ventricular septal defects; a serious complication.

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 perimembranous VSDs.

Methods: Between January 2009 and January 2011, patients diagnosed with perimembranous VSDs eligible for intraoperative device closure with a domestic occluder were identified.

Intraoperative device closure of perimembranous ventricular septal defects in the young children under transthoracic echocardiographic guidance; initial experience.

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 incision was performed after full evaluation of the perimembranous VSD by real-time TTE, and a domestically made device was inserted to occlude the perimembranous VSD.
