A 44-year-old female presented with prosthetic valve endocarditis with periannular abscess involving the left coronary ostium. We describe cryopreserved aortic homograft root replacement with hemi-Cabrol reimplantation of the left coronary ostium using the long saphenous vein.

Background: Patients with pulmonary atresia and ventricular septal defect (PA/VSD) are prone to progressive aortic dilation. However, there are relatively few reports of progressive development of aortic aneurysm or aortic dissection in adult patients who missed early corrective surgery.
Presentation Of Cases: Case 1: A 38-year-old man with PA/VSD and a bicuspid aortic valve (BAV), underwent VSD repair, aortic valve replacement, and PA correction at age 21.

Aortic valve replacements, both surgical and transcatheter, are nowadays widely employed treatments. Although clinically effective, these procedures are correlated with potentially severe clinical complications which can be associated with the non-physiological haemodynamics that they establish. In this work, the fluid dynamics changes produced by surgical and transcatheter aortic valve replacements are analysed and compared with an ideal healthy native valve configuration, employing advanced fluid-structure interaction (FSI) simulations.

Complex N-glycans are asparagine (N)-linked branched sugar chains attached to secretory proteins in eukaryotes. They are produced by modification of N-linked oligosaccharide structures in the endoplasmic reticulum (ER) and Golgi apparatus. Complex N-glycans formed in the Golgi apparatus are often assigned specific roles unique to the host organism, with their roles in plants remaining largely unknown.

Background And Objective: In clinical practice, valve-sparing aortic root replacement surgery primarily addresses left ventricular dysfunction in patients due to severe aortic regurgitation, but there is controversy regarding the choice of surgical technique. In order to investigate which type of valve-sparing aortic root replacement surgeries can achieve better blood flow conditions, this study examines the impact of changes in the geometric morphology of the aortic root on the hemodynamic environment through numerical simulation.
Methods: An idealized model of the aortic root was established based on data obtained from clinical measurements, including using the model of the aortic root without significant lesions as the control group (Model C), while using surgical models of leaflet reimplantation with tubular graft (Model T), leaflet reimplantation with Valsalva graft (Model V), and the Florida sleeve procedure (Model F) as the experimental groups.

Background: Autogenous tooth transplantation offers significant advantages and promising success rates for replacing non-retainable teeth. This study aimed to investigate the prognostic factors, especially the impact of root canal treatment (RCT), of autotransplanted teeth in an up-to-6-year follow-up cohort of 167 teeth in Southern China.
Methods: We enrolled adult patients from the Southern Medical University-Shenzhen Stomatology Hospital between 2017 and 2023.
