LEGDEB2 is a Global Registry for the Treatment of Superficial Femoral and/or Popliteal or Below-The-Knee or Iliac Artery Lesions Using the Legflow Drug-Eluting Balloon
This is a multi-center, post-market, retrospective study design to collect safety and performance data for patients implanted with the Streamline OCT System.
Biliary stricture is a common complication after end-to-end biliary anastomosis, especially after liver transplantation. This study is designed to investigate the safety and efficacy of magnetic recanalization technique, a newly clinical method, for treating biliary anastomotic stricture.
The aim of this study is to determine, in patients with grade 1 degenerative spondylolisthesis with spinal stenosis, if decompression and lumbar spinal fusion with, or without supplementary pedicle screw fixation yields an improved patient reported outcome.
The aim of the work is to; elucidate how the presence of carotid stenosis influence the pattern of stroke and also how it interact with other risk factors for stroke. Also identify predictors of intracranial stenosis and outcome in patients with carotid stenosis with or without intracranial stenosis.
In this study the investigators investigate the feasibility and therapeutic potential of free autologous fat grafting combined to direct visual urethrotomy (DVIU) in the treatment of urethral strictures.
Transcatheter aortic valve replacement (TAVR) has a high risk and a high mortality rate in the treatment of aortic stenosis/regurgitation patients with cardiac insufficiency. The investigators aim to discuss the clinical efficacy of extracorporeal life support system(ECLS) during TAVR procedure in severe aortic lesion under very low ejection fraction (EF).
Purpose of this prospective, randomized, controlled, multi-center study is to evaluate the safety and efficacy of Transcatheter Aortic Valve Implantation (TAVI) as compared to surgical aortic valve replacement (SAVR) in female patients with severe symptomatic aortic stenosis. Patients will be randomized 1:1 to receive either TAVI or SAVR aortic valve replacement. For TAVI procedure, Edwards SAPIEN 3 THV system Model 9600 TFX (20, 23, 26 and 29 mm) or SAPIEN 3 Ultra THV system Model 9750 TFX (20, 23, 26) with the associated transfemoral delivery systems will be sued, for SAVR any commercially available surgical bioprosthetic valve. Patients will undergo the following visits: Screening, Procedure, Post Procedure, Discharge, 30 day, 6 months (telephone contact) and 1 year.
This study aims to identify the molecular genetic causes of the variability in development of calcific aortic valve disease in bicuspid and tricuspid aortic valves and their associated aortic dilation.
