Mid-Term Outcomes of Repair of Coarctation of Aorta With Hypoplastic Arch: Extended End-to-side Anastomosis Technique.

The optimal surgical repair technique for coarctation associated with aortic arch hypoplasia (CoA-AAH) in neonates and infants is controversial. This study evaluates our current strategy using extended end-to-side anastomosis under selective cerebral and myocardial perfusion in treating this group of patients. Through a retrospective review, we analyzed the outcome of 87 infants who underwent surgical repair of CoA-AAH from January 2004 to December 2015.

The clinical outcomes of damus-kaye-stansel procedure according to surgical technique.

Background: The Damus-Kaye-Stansel (DKS) procedure is a method for mitigating the risk of systemic ventricular outflow tract obstruction (SVOTO). However, there have been few reports on which surgical technique shows a better outcome. The objective of this study was to compare the outcome of the DKS procedure according to the surgical technique used.

Extracardiac conduit fontan operation and right ventricular exclusion procedure for right ventricle failure after repair of partial atrioventricular septal defect.

A 13-year-old girl, who had undergone the total correction of partial atrioventricular septal defect at the age of 4 years, was admitted with severe tricuspid regurgitation in echocardiography. She had received one-and-a-half ventricle repair during follow-up. Her right ventricle showed global akinesia, and the ejection fraction of the left ventricle was 25% with paradoxical interventricular septal motion.

Unroofing intramural coronary artery for late coronary events after arterial switch operation.

The incidence of intramural coronary arteries in patients with transposition of the great arteries is relatively rare. Intramural coronary arteries are highly associated with early and late coronary adverse events. We report a case of late coronary events caused by an intramural left coronary artery, which was successfully treated by the unroofing procedure.

Aortopexy with preoperative computed tomography and intraoperative bronchoscopy for patients with central airway obstruction after surgery for congenital heart disease: postoperative computed tomography results and clinical outcomes.

Bronchoscopy-guided aortopexy is a surgical management option for patients with central airway obstruction after congenital heart surgery. This study aimed to evaluate the usefulness of bronchoscopy-guided aortopexy based on midterm follow-up evaluation with computed tomography (CT) and clinical outcome. From January 2004 to August 2011, bronchoscopy-guided aortopexy was performed for 16 patients (median age 0.

Five-year experience with mini-volume priming in infants ≤5 kg: safety of significantly smaller transfusion volumes.

Reducing the cardiopulmonary bypass (CPB) priming volume in congenital cardiac surgery is important because it is associated with fewer transfusions. This retrospective study was designed to compare safety and transfusion volumes between the mini-volume priming (MP) and conventional priming (CP) methods. Between 2007 and 2012, congenital heart surgery using CPB was performed on 480 infants (≤5 kg): the MP method was used in 331 infants (MP group, 69.

The mid-term surgical results of Fontan conversion with antiarrhythmia surgery.

Objectives: We investigated the mid-term surgical results of Fontan conversion with antiarrhythmias surgery and permanent pacemaker implantation, which were complications of a previous Fontan operation.

Methods: From January 1996 to November 2011, we performed Fontan conversion in 31 of 260 Fontan cases (M:F = 17:14, mean age = 19.0 years).

Changes of the Structural and Biomechanical Properties of the Bovine Pericardium after the Removal of α-Gal Epitopes by Decellularization and α-Galactosidase Treatment.

Background: Bovine pericardium is one of the most widely used materials in bioprosthetic heart valves. Immunologic responses have been implicated as potential causes of limited durability of xenogenic valves. This study aimed to determine the effectiveness of decellularization and α-galactosidase (α-gal) to remove major xenoreactive antigens from xenogenic tissues.
