Mechanisms of Excess Risk in Aortic Stenosis
Aortic stenosis (AS) is caused by narrowing of one of the main heart valves. Replacing the valve is the only treatment to prevent the heart from failing or death. The timing of replacement is currently often too late - half of patients are left with permanent scarring and a quarter …
Left Ventricular Reverse Remodeling Evaluation After Surgical Correction of Aortic Regurgitation
Investigators assume that surgical correction approach to functional mitral regurgitation during intervention for chronic aortic regurgitation in patients with severe enlargement of the left heart chambers influences reverse remodeling of the left ventricle (LV) in the postoperative period. It is suggested that functional mitral regurgitation (MR) provides supra-physiological left ventricle …
Development and Validation of the Prediction Model for Functional Mitral Regurgitation Regression in Heart Failure Patients Taking Guideline-directed Medical Therapy
This observational study is to develop and validate the prediction model for functional mitral regurgitation regression in heart failure patients taking GDMT. The patients diagnosed ≥2+ functional mitral regurgitation by ultrasonic cardiogram are enrolled in this study and would be clinically followed by at least one year (clinical visit at …
In Search of Best Practices for Patients With Heart Failure and Secondary Mitral Regurgitation: An Evaluation of the Inova Heart Failure Treatment Algorithm
The overarching goal of this research proposal is to study the feasibility and clinical impact of implementing an Inova system-wide heart failure treatment algorithm for patients with symptomatic heart failure due to reduced left ventricular ejection fraction (HFreF) and secondary MR Aim is to check the effectiveness of the IHFTA …
Correlation of FFR and iFR With Cardiac PET Perfusion in Patients With Severe Aortic Valve Stenosis
Aortic valve stenosis (AS) affects 2-7% of persons > 65 years, symptoms include: angina and dyspnea, dizziness and syncope. Coincidence of coronary artery disease (CAD), also presenting with angina and dyspnea, in patients with AS between 40 - 65% . Angina in AS caused by significant reduction of coronary flow …
Long Term Evaluation of Cardiac Arrhythmias After Transcatheter Aortic Valve Implantation -The LOCATE Registry
The purpose of the Long term Evaluation of Cardiac Arrhythmias after Transcatheter Aortic Valve Implantation (LOCATE) Registry is to perform long-term ambulatory monitoring of patients with severe aortic stenosis who undergo trans-catheter aortic valve implantation (TAVI) and develop new onset conduction system abnormalities post-procedure that do not require urgent permanent …
Polish Transcatheter Transfemoral Mitral Valve-in-Valve Implantation (Mitral ViV) Registry
In recent years increasing number of mitral bioprosthesis implantation, especially in elderly population, is observed. Bioprosthetic valves are associated with a lower risk of thrombotic and bleeding adverse events compared with mechanical prostheses, but their use is limited due to their durability. After years numerous patients may develop bioprosthesis failure, …
COronary Re-engageMent aFter randOm NavitoR alignmenT (COMFORT STUDY)
Whereas PCI before TAVR was previously recommended despite its uncertain prognostic role, recent data underline the possibility of a postponed coronary intervention using a commissural alignment technique. This approach allows easy coronary re-engagement through the valve stent frame with a trade off paid of procedure complexity. Considering the prevalence of …
Novel Echocardiographic Biomarkers Assessing the Myocardial Work in Heart Failure
This study seeks to investigate the clinical value of novel echocardiographic indices, including myocardial work parameters, during the acute phase of heart failure hospitalization. The trajectory of novel echocardiographic indices from the start to the end of hospitalization will be captured, as a means to unravel and subsequently better understand …
Valve Performance of the SAPIEN 3 Ultra RESILIA Valve: a Prospective Registry with Central Echocardiography Analysis.
The issue of valve durability has become one of the most important aspects in the TAVR field in recent years since transcatheter aortic valve replacement has been progressively applied to younger patients with a low co-morbidity burden. The SAPIEN 3 Ultra RESILIA valve represents the last generation of the SAPIEN …
