Filter by:Aortic valve bicuspid disease is the most common congenital heart disease. It affects 0.5-2% of the population and is associated with an increased risk of developing aortic or ascending aortic valve complications. There is no agreement regarding the opportunity for a "prophylactic" simultaneous aortic valve replacement in the case of mild or moderate aortic valve disease in the bicuspid valve, in patients with an indication for replacement of the ascending aorta due to an aneurysm involving its supra-coronary tract. The aim of this study is to evaluate the long-term evolution of mild and moderate aortic valve disease in untreated bicuspid valve during supracoronary ascending aortic replacement surgery at our institution.
The goal of this prospective, non-randomized, single-center, observational study is to assess whether there is a progressive dilation of ascending aorta after surgical or transcatheter aortic valve replacement (TAVR) in patients who underwent elective aortic valve replacement or TAVR for stenotic bicuspid aortic valve (BAV) at our institution from 2015 to June 2022. Participants will undergo both a CT and an echocardiographic assessment at least 90 days after surgery.
Clarification of indications for surgical correction in patients with borderline expansion of the ascending aorta
SASH Trial is a multicenter, prospective, open and randomized 1:1 study. The aim of this study is to evaluate the efficacy of TDM-621(Three-D Matrix- 621) (PuraStat®) on hemostasis of ascending aortic surgery. The TDM-621 is a topic hemostatic product. When in contact with blood it allowed to cover the sutures improving the hemostasis. The hypothesis is that the use of TDM-621 may reduce bleeding and the need for blood transfusion of patients undergoing ascending aortic surgeries. It will include 200 consecutive patients randomized to receive TDM-621 or regular procedure, performed in 5 different centers.
The ascending aorta conducts blood from the heart to the rest of the body. The ascending aorta can become enlarged, and the risk of tearing and rupturing becomes higher with larger aorta. When the ascending aorta tears or ruptures, the risk dying is high even if surgery is done as soon as possible. Traditionally, when the ascending aorta gets above 5.5 cm, surgery is recommended to replace the aorta. However, this threshold is based relatively weak evidence, and sometimes patients with smaller aorta can tear or rupture. On the other hand, surgery carries its own risk as well. Since there are risk of waiting or doing surgery, there is currently no great support for either approach for patients with a smaller aorta. In the TITAN SvS trial, patients with an ascending aorta between 5.0 to 5.5 cm is assigned by chance to the early surgery group, in which they will undergo replacement of aorta, or the surveillance group, in which they will be closely monitored. The chance of dying or suffer tearing or rupture of aorta between the two groups will be compared. The result of the trial will guide future practice for patients with enlarged ascending aorta. This is a prospective, multi-centre randomized control trial that compares the all-cause mortality, aneurysm-related aortic events, rate of stroke, and quality of life for those patients undergoing early elective ascending aortic surgery to those patients undergoing surveillance. Patients referred for an ascending aortic aneurysm that meets the inclusion criteria will be randomized to the early elective surgery group or the surveillance group. Recruitment will end when the desired sample size is reached, and the patients will be followed for a minimum 2-year period. The primary objective of the trial is to compare the composite outcome of the all-cause mortality and incidence of acute aortic events between surveillance and elective ascending aortic surgery for patients with degenerative or bicuspid valve-related ascending aortic aneurysm after 2 years of follow up. The hypothesis is that the early surgery group will have a significantly lower all-cause mortality and incidence of acute aortic events at 2 years of follow up compare to the surveillance group. The result of this trial will provide evidence based guidance in the appropriate management of ascending aortic aneurysm based on the size criteria, and establish a large database for future investigations.
The purpose of this study is to evaluate visceral function, after endovascular repair of thoracoabdominal aneurysms or ascending/aortic arch aneurysms.
The purpose of this study is to assess the role endovascular therapy to treat aortic disease involving the ascending aorta, the aortic arch, and the visceral segment of the aorta (or thoracoabdominal aorta)
