Blunt traumatic aortic tear is an extremely rare and life-threatening paediatric emergency. Percutaneous repair is highly debateable in children due to anatomic limitations. Herein, we report an important case of a 5-year-old boy diagnosed with grade 3 aortic isthmus disruption following fifth-floor defenestration. The 96-h control computerized tomography (CT) scan showed an increase in the pseudoaneurysm size with small active bleeding motivating endovascular covered stenting that was safely and efficiently performed with good outcomes.

Purpose: To correct maternal breathing and fetal bulk motion during fetal 4D flow MRI.
Methods: A Doppler-ultrasound fetal cardiac-gated free-running 4D flow acquisition was corrected post hoc for maternal respiratory and fetal bulk motion in separate automated steps, with optional manual intervention to assess and limit fetal motion artifacts. Compressed-sensing reconstruction with a data outlier rejection algorithm was adapted from previous work.

Coarctation of the aorta (CoA) is a potentially life-threatening congenital and obstructive anomaly of the distal aortic arch. After constriction of the ductus arteriosus, neonates may develop critical CoA in the isthmus area and present with severe left ventricular dysfunction or even cardiac failure. Low cardiac output and abdominal hypoperfusion (distal to the coarctation) may lead to metabolic derangements and clinical deterioration.

Background: Our study aimed to develop a novel diagnostic model for fetal coarctation of the aorta with ventricular septal defect(CoA/VSD).
Methods And Results: We respectively included 70 fetuses with suspected CoA/VSD(January 2017-June 2023). After birth, 26 fetuses (26/47, 55.

A 77-year-old man had severe aortic stenosis and continuous atrial fibrillation. We performed maze procedure without left atrial incision( Dallas lesion set) during aortic valve replacement for this patient. Dallas lesion set alternates the isolation of mitral isthmus by connecting ablation line beneath left coronary cusp and noncoronary cusp commissure of the aortic valve with ablation from epicardial side of the upper left atrium.

Article Synopsis
- The study aimed to establish reference values for fetal 4D flow MRI and assess its reliability in measuring blood flow in healthy fetuses and those with suspected aortic coarctation (CoA).
- Researchers conducted MRI scans on 34 pregnant patients, collecting data from both healthy fetuses and those with potential cardiovascular issues, analyzing the accuracy and consistency of the flow measurements obtained.
- The results indicated that fetal 4D flow MRI provides reliable hemodynamic measurements with high precision and repeatability, although it tends to underestimate blood flow compared to traditional 2D phase contrast MRI techniques.
