According to the data obtained by different authors, postoperative mortality in this cohort of patients varies from 41.7 to 53%.

Surgical Repair of Anomalous Origin of the Left Subclavian Artery From the Pulmonary Artery Using a Supraclavicular Approach.

Anomalous origin of the left subclavian artery from the pulmonary artery is a rare congenital cardiac malformation. We describe a case of anomalous origin of the left subclavian artery from the pulmonary artery in a patient who presented with symptoms of vertebrobasilar insufficiency and underwent reimplantation of the left subclavian artery into the left common carotid artery from the supraclavicular approach.

Single-stage off-pump repair of coarctation of the aorta and ventricular septal defects in children.

Objectives: The appropriate approach for surgical repair of coarctation of the aorta with a ventricular septal defect (VSD) remains controversial. This study evaluated the outcomes of primary repair of VSDs with periventricular device closure without cardiopulmonary bypass through a left thoracotomy in patients without arch hypoplasia.

Methods: We selected 21 patients aged <1 year, including 7 neonates, who underwent repair of coarctation of the aorta with periventricular device closure of a VSD.

Effects of Electrospinning Parameter Adjustment on the Mechanical Behavior of Poly-ε-caprolactone Vascular Scaffolds.

Electrospinning is a perspective method widely suggested for use in bioengineering applications, but the variability in currently available data and equipment necessitates additional research to ascertain the desirable methodology. In this study, we aimed to describe the effects of electrospinning technique alterations on the structural and mechanical properties of (1,7)-polyoxepan-2-one (poly-ε-caprolactone, PCL) scaffolds, such as circumferential and longitudinal stress/strain curves, in comparison with corresponding properties of fresh rat aorta samples. Scaffolds manufactured under different electrospinning modes were analyzed and evaluated using scanning electronic microscopy as well as uniaxial longitudinal and circumferential tensile tests.

Objective: To determine whether intraoperative administration of dexamethasone is more effective than placebo for reducing major complications and mortality during pediatric cardiac surgery.

Design, Setting, And Participants: The Intraoperative Dexamethasone in Pediatric Cardiac Surgery was an investigator-initiated, double-blind, multicenter randomized trial that involved 4 centers in China, Brazil, and Russia.

Selective Antegrade Cerebral Perfusion With or Without Additional Lower Body Perfusion During Aortic Arch Reconstruction in Infants.

Background: Aortic arch reconstruction is often challenging, especially in infants, owing to its high postoperative complication risks. This study aimed to compare the effectiveness between selective antegrade cerebral perfusion (SACP) alone and SACP in combination with continuous lower body perfusion with descending aortic cannulation (DAC) in preserving renal function, and to determine the influence of perfusion strategy on the postoperative course of infants who underwent aortic arch reconstruction.

Material And Methods: A total of 121 infants who underwent aortic arch reconstruction between January 2008 and December 2018 were included in the analysis.

Vacuum-assisted closure versus closed irrigation for deep sternal wound infection treatment in infants: a propensity score-matched study.

Objectives: This study aimed to compare vacuum-assisted closure therapy (VAC) and closed irrigation drainage therapy (CID) for deep sternal wound infection treatment in infants.

Methods: From January 2008 to March 2018, 69 patients (1.73%) had deep sternal wound infection.

Double Arterial Cannulation in the Critical Management of Neonatal Aortic Arch Obstruction With Closed Ductus Arteriosus.

The neonatal management of critical aortic arch obstruction in association with an arterial duct that remains closed or significantly constricted requires urgent surgical repair, with a postoperative focus on resolving the impaired function of compromised organs. Here, we present two neonatal cases illustrating the use of the dual arterial cannulation perfusion method in the complete repair of interrupted aortic arch and critical coarctation of the aorta with nonfunctional ductus arteriosus. We suggest that dual arterial cannulation, which provides total body perfusion (with the exception of cardiac perfusion during cardioplegic arrest of the heart), may be a good alternative to other perfusion strategies in cases of absent ductal blood flow, as this method allowed us to avoid the further development of severe multiple organ failure.

Extracorporeal cardiopulmonary resuscitation after pulmonary artery rupture.

Pulmonary artery rupture during pulmonary balloon valvuloplasty is a rare and life-threatening complication. Here, we present a pulmonary artery rupture in a 10-month-old infant. The patient had a tamponade, ineffective cardiac massage for 40 minutes and extreme hemodilution due to blood loss.

Postcardiotomy refractory ventricular fibrillation: rescue using veno-arterial extracorporeal membrane oxygenation.

We present a case of 7-hour ventricular fibrillation with successful use of veno-arterial extracorporeal membrane oxygenation as a bridge to recovery in a 30-year-old patient with grown-up congenital heart disease who underwent pulmonary valve replacement.

Does mitral valve repair matter in infants with ventricular septal defect combined with mitral regurgitation?

Objectives: This study aimed to assess mitral valve function after repair of ventricular septal defect (VSD) combined with mitral regurgitation (MR) in the mid-term follow-up period, to evaluate the clinical utility of simultaneous mitral valve repair (MVR).

Methods: From June 2005 to March 2014, 60 patients with VSD and MR underwent surgical treatment. After performing propensity score analysis (1:1) for the entire sample, 46 patients were selected and divided into 2 groups: those with VSD closure and MVR (VSD + MVR, 23 patients) and those with VSD closure without mitral valve intervention (VSD only, 23 patients).
