Filter by:The TAVI - Register is a Germany-wide scientific elevation in which data about the aortic valve treatment and the therapeutic consequences are documented.
This study will quantify the safety and efficacy of the CardioCel implant in tri-leaflet repair. 80 patients in up to 7 sites in Europe and the US will all be treated with the CardioCel implant.
Ambulation following surgery has been found to be beneficial for patients; however, nurses and doctors struggle with getting post-operative, hospitalized patients to walk on their own. One promising strategy to address this might be an ambulation orderly, an employee whose single responsibility is to assure that patients walk 3-4 times per day. However, the effect of the ambulation orderly on post-operative physical activity has not yet been described. It is important to quantify what the ambulation orderly does in order to assess if this is an effective method for helping patients walk. As a result, the investigators will perform a pilot randomized controlled trial to test the effects of an ambulation orderly in patients hospitalized with recent cardiac surgery. Half of the patients will be assigned to walk with the ambulation orderly 3-4 times/day and the control group will be given standard nursing encouragement and assistance and encouragement to walk. The investigators will evaluate the average total daily step counts (over the hospital course, usually 4-7 days) and the change in walking distance between a baseline and a final 6 minute walk test. The investigators will also evaluate exercise physiologic parameters (heart rate, oxygen saturation) during ambulation, patient functional independence, and patient satisfaction.
Prospective longitudinal study on four small groups of surgical patients affected by: BAV with isolated regurgitation, BAV associated with aorta dilatation, or both and BAV with isolated stenosis in over 60 year-old patients. The aim of the study is to select homogeneous small groups of surgical patients with the same subtype of BAV and same aortic behaviour and identify markers/predictors of favorable-unfavorable aortic wall evolution to evaluate if there is a BAV phenotype more likely to be considered at high risk for aortic degeneration.
The HAART 200 "Aortic Annuloplasty during Bicuspid Aortic Valve Reconstruction" Trial is a prospective, non-randomized, multi-center trial to evaluate the safety and effectiveness of the HAART 200 bicuspid annuloplasty ring when used to surgically stabilize the aortic valve annulus in patients undergoing repair of bicuspid aortic valves (BAV) for predominant aortic insufficiency (AI).
Use of vasopressor to maintain Mean Arterial Pressure on Cardio Pulmonary Bypass can lead to decreased cerebral flow and oxygenation in individual patients and this can be detected by means of cerebral oxymetry.
Authors hypothesize that aortic root reimplantation procedure is superior over standard aortic valve reimplantation procedure in the incidence of aortic valve replacement.
This investigation is a prospective, non-randomized, multi-center trial to evaluate the extended safety and performance of the HAART model 300 annuloplasty ring when used to surgically repair the aortic valve using a 3-D intra-annular mounting frame.
The EASE Enable study is intended to collect additional data on the clinical outcomes of the Medtronic Enable® Aortic Bioprosthesis in "real world" patients.
The purpose of the clinical study is to prove that the heart valve device is safe, effective, and performs as intended.
