Summary: This study assessed exercise capacity and ventricular function in patients after arterial switch operation (ASO) for complete transposition of the great arteries. It found that some asymptomatic ASO patients have electrical, left ventricle, and right ventricle changes at rest, and signs of fibrosis. Exercise capacity is impaired and seems to be related to ventricular function.

Summary: 3D modeling can predict late coronary events after ASO, with the geometric parameters of the left coronary artery being associated with coronary events and having predictive value.

Summary: For patients with d-TGA and a systemic right ventricle after atrial switch surgery, the progression to end-stage heart failure or death is slow. The study identified predictive factors associated with adverse outcomes and developed a simplified scoring system to identify high-risk patients.

Summary: This study evaluated the 90-day mortality and the effect of rescue or urgent coronary revascularization in children undergoing arterial switch operation for transposition of the great arteries. The 90-day mortality was found to better represent perioperative outcomes compared to the 30-day mortality. Patients on ECMO had a higher 90-day mortality, and coronary revascularization showed a salvaging effect.

Summary: Patients with TGA after ASO often have different PA anatomy and common PA stenoses. This study used MRI to establish disease-specific reference ranges for PA dimensions and biventricular volumes and mass in 69 pediatric patients with TGA. The results showed strong associations between body surface area and PA diameters, as well as between height and biventricular volumes.

Summary: The long-term survival of children undergoing ASO is excellent with low rates of coronary artery reinterventions. Patients with intramural coronary artery are at higher risk of coronary artery reintervention and mortality.

Summary: This study aimed to assess cerebral perfusion in neonates with transposition of the great arteries (TGA) undergoing arterial switch operation (ASO) using transfontanellar contrast-enhanced US (T-CEUS). The results revealed reduced cerebral perfusion in neonates under low-flow hypothermic conditions, which was inversely correlated with age at surgery.

Summary: In patients with transposition of the great arteries, aortopulmonary collateral arteries are common after catheterization. This case report describes symptomatic aortopulmonary collateral arteries following arterial switch, which required support with a centrifugal pump and left ventricular assistive device, along with emergent coil embolization. After embolization, hemodynamics significantly improved, and the postoperative recovery was uneventful.

Summary: This study investigated the contemporary outcomes of the double switch operation for patients with congenitally corrected transposition of the great arteries. The results showed promising outcomes of the surgery, but highlighted the anticipated problems of progressive neoaortic regurgitation and the need for reoperations.

Summary: This study conducted a comprehensive haemodynamic analysis using 4D-flow MRI data to investigate the relationship between aorta dilation in TGA patients post-ASO and controls. Significant differences in haemodynamic parameters were found between the two groups, with potential biomarkers identified for early prediction of aortic root dilatation in TGA patients.

Summary: This study retrospectively examined the impact of an improved coronary transfer technique in arterial switch operation for transposition of the great arteries. The oblique coronary transfer technique showed good patency of the coronary arteries and contributed to improved postoperative mortality rates, with no deaths and no need for mechanical circulatory support during a median follow-up of 5.3 years. The freedom from re-intervention rate was 85.6% over 8 years, with most transplanted coronary arteries remaining patent.

Summary: This study aimed to evaluate the long-term outcomes of patients undergoing ASO at a single institution. The results showed high survival rates and normal LV systolic function in patients after 25 years of ASO surgery. However, some patients may face issues such as neoaortic valve regurgitation and the need for reoperation.

Summary: Patients with bicuspid native pulmonary valve (BNPV) undergoing arterial switch operation have similar short-term outcomes compared to those with tricuspid native pulmonary valve, but are more prone to and experience earlier aortic regurgitation and neo-aortic root dilation.

Summary: Research suggests that common genetic variants may contribute to the heterogeneity in clinical course and improve risk stratification in patients with transposition of the great arteries after atrial switch operation. These findings support the hypothesis that incorporating genetic variants into risk assessment may be beneficial.
