Left Main Coronary Artery Ostial Stenosis Caused by Syphilitic Aortitis Presenting With Syncope.
JACC Case Rep
January 2025
Department of Cardiovascular Medicine, Kobe City Medical Center General Hospital, Kobe, Japan.
A 51-year-old man with a history of antibiotic therapy for syphilis 1 month ago presented with syncope. Computed tomography revealed circumferential aortic wall thickening complicating severe stenosis of left main coronary ostium. Abnormalities in serologic and cerebrospinal fluid tests led to the diagnosis of syphilitic aortitis and neurosyphilis.

Department of Vascular and Endovascular Surgery, Heart and Vascular Center, Semmelweis University, Budapest, Hungary.
Aims: To test utility of diffusion MRI-derived indices in carotid endarterectomy (CEA), change of diffusion tensor imaging (DTI) metrics, cerebral white matter (WM) volumes were evaluated and predictors of overall mortality determined.
Methods: Prospectively enrolled participants had preoperative, immediate and late postoperative DTI after CEA. WM volumes, DTI metrics (fractional anisotropy, FA; axial, radial, mean diffusivities; AD, RD, MD, respectively) were calculated for the index/contralateral hemispheres at all time points.
Aortic valve repair with sinus plication for a regurgitant bicuspid aortic valve: a case report.
Gen Thorac Cardiovasc Surg Cases
January 2025
Osaka Metropolitan University Graduate School of Medicine, 1-4-3, Asahimachi, Abeno-Ku, Osaka, 545-8585, Japan.
Background: Repair of the regurgitant bicuspid aortic valve is an attractive alternative to valve replacement. Although good long-term outcomes have been reported, postoperative aortic stenosis remains a major late cause of repair failure in bicuspid aortic valves. Sinus plication is effective for creating a more symmetrical commissural angle, leading to a decrease in the mean transvalvular pressure gradient.

Heart Rhythm O2
December 2024
Faculty of Health Sciences, Ben-Gurion University of the Negev, Beer Sheva, Israel.
Background: Transcatheter aortic valve replacement (TAVR) has revolutionized the management of aortic stenosis and has become the standard of care across a broad spectrum of patients with aortic stenosis. However, it is still associated with high incidence of conduction abnormalities, particularly new left bundle branch block (LBBB). Management of these patients remains a challenge.

J Blood Med
January 2025
Department of Blood Transfusion of Yong-chuan Hospital, Chongqing Medical University, Chongqing, 402160, People's Republic of China.
Purpose: To study the platelet adhesion and aggregation behaviour of late pregnancy women under arterial shear rate using microfluidic chip technology and evaluate the risk of thrombosis in late pregnancy.
Methods: We included pregnant women who were registered in the obstetrics department of our hospital between January 2021 and October 2022 and underwent regular prenatal examinations. Blood samples were collected at 32-35 weeks of gestation for routine blood tests and progesterone, oestradiol, and platelet aggregation function.
