Objectives: To describe the workflow and value of three-dimensional rotational angiography (3DRA) in percutaneous pulmonary valve implantation (PPVI).
Background: 3DRA offers visualization of the entire topography in the chest and may enhance safety and reduce the risk for complications in PPVI through improved pre-procedural planning and per-procedural guidance.
Methods: All PPVI procedures with the use of 3DRA performed between August 2011 and December 2022 were reviewed.
Article Synopsis
- The study assessed the long-term clinical outcomes of patients who underwent an arterial switch operation (ASO) for transposition of the great arteries (TGA), highlighting a growing patient population.
- Findings indicated that at age 35, the survival rate was high at 93%, but a significant percentage (36%) required re-interventions, particularly affecting the right ventricular outflow tract.
- The research concluded that while survival rates are favorable, continuous monitoring and potential interventions are necessary throughout the patients' lives, with specific subtypes of TGA presenting higher risks for complications.
Background: Due to medical and surgical advancements, the population of adult patients with congenital heart disease (ACHD) is growing. Despite successful therapy, ACHD patients face structural sequalae, placing them at increased risk for heart failure and arrhythmias. Left and right ventricular function are important predictors for adverse clinical outcomes.

- - Pulmonary artery (PA) stenosis is a frequent issue after the arterial switch operation (ASO) for transposition of the great arteries (TGA), and this study aimed to compare flow measurements using 4D flow CMR and 2D phase-contrast MRI (2D PCMR) alongside echocardiography.
- - The research included 39 patients, revealing that 4D flow CMR consistently reported higher maximum velocities for PAs than 2D PCMR (significant difference of 65 cm/s for the main PA and 77 cm/s for the side PAs).
- - Echocardiography was often ineffective for PA assessment in most patients, while stroke volume measurements showed a good
Background: From 1977 onwards, patients with both simple and complex transposition of the great arteries (TGA) have been treated with the arterial switch operation (ASO) in the Wilhelmina Children's Hospital/University Medical Center Utrecht the Netherlands. In this study, we compared mortality and morbidity between two patient groups: A. operated before and B.
