Background: Late ventricular failure remains a major concern in patients with congenitally corrected transposition of the great arteries (ccTGA). A new treatment for this condition is the double-switch procedure.
Methods: Three consecutive children with atrioventricular and ventriculoarterial discordance (congenitally corrected transposition of the great arteries) and associated ventricular septal defect underwent pulmonary artery banding in infancy, followed by a double-switch procedure and closure of the ventricular septal defect at a median age of 5.8 years (range 4.5 to 6 years).
Results: There were no major procedure-related complications and the median duration of hospital stay was 13 days. One patient required stent implantation in the superior vena cava five months after surgery to relieve a persistent caval stenosis associated with recurrent pleural and pericardial effusions. Apart from this, no other complications have occurred over a median follow-up of five months.
Conclusion: The double-switch procedure offers the potential advantage of restoring the morphological left ventricle to systemic ventricle. Longer-term follow-up of this procedure is warranted.

Short- and Long-Term Outcomes of Patients Who Underwent the Arterial Switch Operation at Siriraj Hospital-Thailand's Largest National Tertiary Referral Center.
World J Pediatr Congenit Heart Surg
January 2025
Division of Cardiothoracic Surgery, Department of Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand.
Objective: The aim of this study was to assess the short- and long-term outcomes of patients who underwent the arterial switch operation (ASO) at Siriraj Hospital in Thailand, and to identify postoperative complications and factors that significantly affect patient survival.
Materials And Methods: We retrospectively studied all patients with dextro-transposition of the great arteries and anatomic variants who underwent the ASO from January 1995 to December 2020. Twenty-year overall survival and 15-year freedom from reoperation/reintervention were estimated using the Kaplan-Meier method.

Objectives: Mixed reality (MixR) is an innovative visualization tool that presents virtual elements in a real-world environment, enabling real-time interaction between the user and the combined digital/physical reality. We aimed to explore the feasibility of MixR in enhancing preoperative planning and intraoperative guidance for the correction of various complex congenital heart defects (CHDs).
Methods: Patients underwent cardiac computed tomography or cardiac magnetic resonance and segmentation of digital imaging and communications in medicine (DICOM) images was performed.

Background: Extracorporeal membrane oxygenation (ECMO) can act as a bridge to recovery in both pre-and postoperative patients with transposition of the great arteries (TGA). However, literature on its use in these patients is scarce.
Methods: Retrospective single-centre cohort study encompassing all TGA patients who received ECMO between January 2009 and March 2024.

Background: Arterial switch operation (ASO) for dextro-transposition of the great arteries was developed four decades ago, and women with ASO have reached childbearing age. Although over 40% of the pregnant women who received ASO gave birth via cesarean delivery, detailed information about anesthesia management has not been reported. This study aimed to evaluate anesthesia and perioperative outcomes in pregnant women with ASO undergoing cesarean delivery.

Background: The study focuses on vascular compression of the main bronchus in the aortopulmonary space, examining potential contributors within the same axial plane. Its goal is to uncover mechanisms of bronchial compression in patients with intracardiac anomalies and review surgical outcomes, aiming to enhance future results.
Methods: The morphology and topology of structures within the axial plane of the aortopulmonary space were objectively analyzed, including the sternum, ascending aorta, heart, pulmonary artery, descending aorta, and other relevant elements.
