Pediatric RVOT reconstruction with ePTFE trileaflet valved conduits: a dual-center Chinese study.

Objective: This study aims to assess the early to mid-term clinical efficacy of expanded polytetrafluoroethylene (ePTFE) trileaflet valved conduits in pediatric right ventricular outflow tract reconstruction for congenital heart disease.

Methods: We conducted a retrospective analysis of pediatric patients who underwent right ventricular outflow tract (RVOT) reconstruction using ePTFE trileaflet valved conduits at two cardiac centers in China, between January 2017 and June 2023. The main assessment criterion was the functionality of the prosthetic pulmonary valve conduit.

Subepicardial lipoma of the posterior atrioventricular sulcus in children: a case report and review of the literature.

Cardiac lipoma is rarely reported in the pediatric population. We reported a case of subepicardial lipoma of the posterior atrioventricular sulcus in a child. The tumor was resected successfully and the patient recovered well after the operation.

Intraatrial conduit Fontan procedure: indications, operative techniques, and clinical outcomes.

Background: The intraatrial conduit (IAC) Fontan procedure is one of the Fontan modifications and is usually not considered the first choice. In this large series, we report our experience of the IAC Fontan procedure for the treatment of a functional single ventricle and review its indications, techniques, and clinical outcomes.

Methods: Between 2009 and 2013, 101 patients with a functional single ventricle underwent an IAC Fontan procedure.

[Visualization of the age-related changes in expressions of DNA methyltransferases in mouse oocytes using two-photon imaging system].

Quantum dot (QD) is widely used as fluorescent labeling dye for its strong anti-fluorescence quenching, high quantum yield, wide absorption spectra, and narrow emission spectra. In the present paper, QD 585-labeled DNA methyltransferases (Dnmts) and Hoechst 33342-labeled chromosomes were imaged simultaneously using two-photon imaging system. The authors' results showed that aging mouse oocytes may be not suitable for in-vitro maturation: both the localizations and expression levels of Dnmts in in-vitro matured oocytes of aging mice were changed, and these changes may be related to the abnormal DNA methylation modification.

[Judgement of the left ventricle retraining in the rapid two stage-switch operation].

Objectives: To Summarize the results of left ventricle retraining in rapid two-stage switch operation and to determine the estimating index of left ventricle retraining and the best time of the second stage operation.

Methods: From September 2002 to September 2007, 21 patients underwent rapid two stage switch operation. There were 13 male and 8 female patients, ageing from 29 to 250 d [mean (103 ± 69) d, median 75 d], weighting from 3.

Involvement of a novel GATA4 mutation in atrial septal defects.

Atrial septal defect (ASD) is one of the most common types of congenital heart disease and is associated with a significant increase in the morbidity and mortality of affected individuals. Accumulating evidence indicates that genetic defects play important roles in the pathogenesis of congenital ASD. However, ASD is genetically heterogeneous and the genetic determinants for ASD in the majority of the patients remain to be identified.

Novel NKX2-5 mutations in patients with familial atrial septal defects.

Atrial septal defect (ASD) is a common cardiovascular malformation and an important contributor to substantial morbidity and mortality. Increasing evidence demonstrates that mutated NKX2-5, a gene encoding a homeobox transcription factor crucial to cardiogenesis, is a significant genetic determinant for congenital ASD. Nevertheless, the genetic basis for ASD in a majority of ASD patients remains largely unknown.

[Novel GATA4 mutations identified in patients with congenital atrial septal defects].

Objective: To identify the genetic defects in patients with congenital atrial septal defects (ASD).

Methods: The clinical data and blood samples from 180 unrelated subjects with congenital ASD were collected and evaluated. Two hundred healthy individuals served as controls.

[Effect of prone or spine position on mechanically ventilated neonates after cardiac surgery with acute lung injury].

Objective: To compare the efficacy and safety ventilated with pressure support ventilation (PSV) or neurally adjusted ventilatory assist (NAVA) in neonates undergoing open-heart surgery with acute lung injury (ALI) in spine and prone positions.

Methods: Fifteen neonates with a mean age of (15 +/- 9) days and a mean weight of (3.5 +/- 0.

[Staged surgical treatment of pulmonary atresia with ventricular septal defect].

Objective: To determine the choice of palliative procedures, timing and techniques of second-stage operations.

Methods: Between April 2004 to July 2008, 50 consecutive patients with pulmonary atresia with ventricular septal defect (PA/VSD) underwent two-stage operation. Palliative procedures included modified Blalock-Taussig shunt (n = 5), central shunt (n = 2), pericardial patch enlargement (n = 10), pericardial tube (n = 4) and Gore-Tex conduit (n = 29).

Evaluation of early macrophage activation and NF-kappaB activity in pulmonary injury caused by deep hypothermia circulatory arrest: an experimental study.

This study aimed to analyze changes in nuclear factor-kappa B (NF-kappaB), inflammation factors, and macrophages in pulmonary tissue under deep hypothermia circulatory arrest (DHCA) at different time points, which can be used to infer the role of early macrophage activation and NF-kappaB activity in pulmonary injury. The possible pathogenic mechanisms of DHCA-induced pulmonary injury were investigated in this study to provide an experimental basis for clinical lung protective strategies. Piglets (n = 12) were randomly divided into 2 groups, with 6 piglets in each group.

Arterial switch operation with coronary arteries from a single sinus in infants.

Background: The implantation of a coronary artery (CA) is critical for the arterial switch operation (ASO) done to treat complete transposition of the great arteries (TGA). Coronary artery abnormalities are risk factors for both early and late mortality after surgery. In this study, the methodology and effects of ASO surgery with coronary arteries from a single sinus were evaluated.

Use of the lecompte procedure for ventriculoarterial connection abnormalities in infants and children with congenital heart diseases.

Background: The Lecompte (REV) procedure is used to correct abnormal ventriculoarterial connections in patients with congenital heart diseases; it avoids the need for an extracardiac conduit for pulmonary outflow tract reconstruction. The present study aimed to investigate effectiveness and criteria of the REV procedure in children with abnormal ventriculoarterial connections.

Methods: Thirty-eight children (mean age, (2.

Surgical experience of coarctation of the aorta in infants and young children.

We evaluated the effectiveness of surgical treatment for coarctation of the aorta in infants and young children, based on our experience over 7 years. From March 1999 to December 2005, 168 cases of coarctation of the aorta in patients aged 21 days to 3 years were treated by end-to-end, extended end-to-end, or extended end-to-side ascending aorta and aortic arch anastomosis. The mortality rate was 0.

Lung perfusion with oxygenated blood during aortic clamping prevents lung injury.

To evaluate the protective effect of continuous pulmonary perfusion with oxygenated blood during aortic crossclamping, 12 mixed-breed piglets (7-12 kg) were placed on cardiopulmonary bypass for 130 minutes. An experiment group of 6 (group E) had continuous pulmonary perfusion with oxygenated blood during cardiopulmonary bypass, while the other 6 served as controls (group C). Pulmonary function was measured at the beginning and end of cardiopulmonary bypass and one hour later.
