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 …
Mixed Reality in MitraClip Implantation: Preliminary Case Series
The study aims to evaluate the impact of mixed reality (MR) technology, particularly using Hololens 2.0 and specialized software for three-dimensional DICOM image visualization, on MitraClip implantation procedures. This preliminary case series includes a comparative analysis of four MitraClip implantations, assessing procedural efficiency, radiation exposure, and operator stress through both …
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 …
Impact of Aortic Annulus Calcification on Long-Term Outcomes Following Transcatheter Aortic Valve Replacement: SAINT-TAVR Calcium Registry
The goal of this observational study is to learn about the long-term effects of aortic valve annular calcification in patients undergoing transcatheter aortic valve replacement (TAVR). The main question it aims to answer is: Does the degree of aortic valve annular calcification prior to TAVR influence long-term clinical outcomes, including …
The Effect of Subclinical Leaflet Thrombosis and Prosthesis Type on Transcatheter Aortic Valve Degeneration (POPular PET TAVI)
A multicentre cross-sectional cohort study to assess the difference in bioprosthetic micro-calcification activity, detected with 18F-NaF PET-CT, as early marker of transcatheter valve degeneration, between patients with vs. without subclinical leaflet thrombosis at five years after TAVI; and between patients with intra-annular vs. supra-annular TAVI prostheses.
TEER for Severe DMR of Low to Intermediate Surgery Risk
To investigate the efficacy and safety of transcatheter mitral valve edge-to-edge repair (TEER) for severe degenerative mitral regurgitation (DMR) patients of low to intermediate surgery risk.
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 …
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 …
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 …
