Stanford A aortic dissection 40 years after aortic valve replacement with a Starr-Edwards caged-ball prosthesis: a case report.

Stanford A aortic dissection is one of the most devastating acute medical conditions due to its high morbidity and mortality. We describe a 77-year-old male patient with a medical history of surgical aortic valve replacement with a still functioning Starr-Edwards caged-ball valve 40 years prior. The patient was promptly diagnosed with an ascending aortic aneurysm and dissection, and an emergency Bentall procedure in deep hypothermic circulatory arrest was performed.

Multi-Center Fetal Brain Tissue Annotation (FeTA) Challenge 2022 Results.

Segmentation is a critical step in analyzing the developing human fetal brain. There have been vast improvements in automatic segmentation methods in the past several years, and the Fetal Brain Tissue Annotation (FeTA) Challenge 2021 helped to establish an excellent standard of fetal brain segmentation. However, FeTA 2021 was a single center study, limiting real-world clinical applicability and acceptance.
