Loss of Y Chromosome in Aortic Stenosis
The most common heart valve disease in humans is aortic stenosis which is a critical narrowing of the valve through which the heart has to pump blood to the rest of the body. This condition occurs in 2-3% of adults over 65 years of age and when it progresses to …
Detecting Changes in Arterial Blood Volume and Cardiac Efficiency
The objective of this Pilot Study is to demonstrate the efficacy of the Hemocept device in detecting changes in arterial blood volume and cardiac efficiency.
Assessing the Relationship Between Symptoms and Mitral Regurgitnant. Severity
The current American College of Cardiology/American Heart Association (ACC/AHA) guidelines recommend surgery in patient with mitral regurgitation (MR) based on 1) the severity of MR and 2) the presence or absence of symptoms. Studies have shown that Cardiovascular Magnetic Resonance (CMR) is an accurate method to quantify the severity of …
Identifying Biological Markers of Cardiovascular Events in Patients With Aortic Stenosis or TAVI
Aortic stenosis, a common cardiovascular disease, is pathophysiologically associated with a chronic inflammatory myocardial reaction and fibrosis leading to cardiac dysfunction and impaired coronary perfusion. These elements may precede the onset of symptoms. The assessment of inflammatory and fibrosis factors (in particular by means of biomarkers) in patients with aortic …
Mitral Valve Annulus Assessment, Multimodality Imaging
The success of mitral valve repair with annuloplasty depends on the repair technique and on the choice of a ring with appropriate dimensions related to mitral annulus. Intraoperatively, the choice of the prosthetic ring size is made by the surgeon using special gauges that are placed on the anterior mitral …
Hydra Registry - UK
The study will evaluate the efficacy and safety of transcatheter aortic valve implantation (TAVI) using the Hydra transcatheter aortic heart valve (THV) series, in patients with severe aortic stenosis up to 1-year after the procedure. This will include an evaluation of the preservation of coronary access post implant by attempting …
A Study of Transcatheter Aortic Valve Replacement Case Selection and Valve Sizing Using the ABC Bicuspid Sizing Algorithm
The goal of this study is to learn what effects the ABC Bicuspid Sizing Algorithm has on the clinical outcomes of patients with bicuspid aortic stenosis after having a transcatheter aortic valve replacement (TAVR) using the Sapien 3 valve. The main questions the study aims to answer are: Does the …
Fibrosis in Chronic and Delayed Myocardial Infarction
In this study the investigators aim to examine the role that fibrosis plays in heart conditions such as aortic stenosis , chemotherapy-induced cardiotoxicity and carcinoid syndrome . Fibrosis is a common final result following any injury to the heart muscle and the investigators aim to identify this process early and …
One Year Pacing Dependency After TAVR
Pace maker implantation after the procedure of TAVR can be estimated at 15% of patients. However, some studies have shown that the conduction disturbances after TAVR could resolve over time, and that roughly between one- and two-thirds of patients who required a permanent pace maker implantation post TAVR were not …
Changes of Ascending Aortic Diameter in Patients Undergoing Transcatheter Aortic Valve Replacement
The goal of this observational study is to assess the changes of ascending aortic diameter in patients undergoing transcatheter aortic valve replacement. The main questions it aims to answer are: whether the ascending aortic diameter increases or remains stable after transcatheter aortic valve replacement, especially in patients with preoperative ascending …
