Filter by:This registry follows patients undergoing two methods of aortic heart valve replacement in adults aged 18-60, the Ross procedure or conventional aortic valve replacement using a biologic or mechanical heart valve. The Ross procedure replaces a patient's diseased aortic valve with his/her own pulmonary valve and uses a donor valve in the pulmonary position which receives less stress than the aortic valve. Mechanical valves tend to form blood clots so they need long-term blood thinners that increase risk of bleeding and lower quality of life. Animal tissue valves reduce clotting and bleeding risks but wear out sooner and shorten patient life-span. The REVIVAL Registry will run in parallel with the REVIVAL randomized trial.
A group of 150 patients undergoing aortic valve replacement procedure will be randomized either into del Nido cardioprotection protocol (75 participants) or into the cold blood cardioplegia protocol (75 participants). The intraoperative and perioperative outcomes of using each solution will be presented and compared (see the endpoints).
This study evaluates the clinical and hemodynamic outcome in patients after aortic valve replacement. Half of the patients will receive warfarin + aspirin and the other half will receive only aspirin. The investigators will focus mainly on early bioprosthesis degeneration.

The purpose of the study is to compare early and 1-year hemodynamic performance and clinical outcomes after aortic valve replacement using two pericardial bioprosthesis, Avalus and Carpentier Edwards Perimount Magna Ease.
The aim of this study is to analyse the short-term results of the first patients undergoing the OZAKI procedure (Aortic valve reconstruction using autologous pericardial tissue) at the department of cardiac surgery/ University Hospital Basel/ Switzerland.
The aim of our study was to investigate, whether enhancement of left atrial cryoablation by ablation of the autonomic nervous system of left atrium leads to influencing the outcomes of surgical treatment of atrial fibrillation in patients with structural heart disease undergoing open-heart surgery.
The main objective of this trial is to investigate the effects of starting exercise rehabilitation earlier than current practice after coronary artery bypass graft(CABG) or Aortic/Mitral valve replacement (VR) surgery.
Patients with aortic stenosis present many risk factors for endothelial dysfunction (arterial hypertension, arteriosclerosis, dyslipidemia, chronic renal insufficiency, etc.). It is likely that a significant number of patients suffer from pre-existing endothelial dysfunction that can be evaluated by a molecular approach. To date, the replacement of the aortic valve can be performed by surgery with extracorporeal circulation (CEC) or percutaneous (Transcatheter Aortic Valve ImplantationTAVI) without CEC. Two recent studies have demonstrated a sustained improvement in endothelial function with TAVI. On the contrary, studies have demonstrated that post-operative complications (coagulopathy, capillary leak syndrome, acute vasoplastic disorder and acute renal failure) after surgery with extracorporeal circulation (CEC) could be the result of the interaction between pre-existing endothelial dysfunction And the "operative" aggression associated with the CEC. Thus, patients with preexisting involvement of endothelial function would develop vascular dysfunction after valvular replacement due to "endothelial activation" related to CEC. This phenomenon would not exist in TAVI, and would explain the absence of so-called vascular dysfunction complications (Systemic inflammatory response syndrome, vasoplastic syndrome, disseminated intravascular coagulation).
The primary objective is to evaluate the performance and the treatment effect of the use of the Emblok embolic protection system use during transcatheter aortic valve replacement with respect to procedure-related cerebral embolic burden as determined by DW-MRI.
