Heart Valve Disease Clinical Trials

The purpose of this research study is to determine if replacing the aortic valve without open-heart surgery is as safe as or safer than open-heart surgery in patients who are considered at low risk for complications from surgery. Subjects in this trial will be compared to similar patients that have ...

Eligibility Criteria: Once you have decided to participate and have learned of the details of the trial you will be seen and evaluated for the following: To be eligible to participate you will be evaluated for Severity of aortic stenosis. You must meet criteria for heart team agreement of low ...

Eligibility Criteria: Inclusion Criteria:•Age > or equal to 18 years of age•History of non-paroxysmal form of AF as defined by the HRS/EHRA/ECAS Consensus Statement:◦Persistent AF shall be defined as continuous AF that is sustained beyond seven days. Episodes of AF in which a decision is made to electrically or pharmacologically ...

The purpose of the study is to assess the safety and efficacy of the 17mm On-X Aortic Prosthetic Heart Valve and the 23mm On-X Mitral Prosthetic Heart Valve when used to replace diseased aortic or mitral valves in human subjects. The On-X 17mm aortic and 23mm mitral valves will be ...

This is a longitudinal, randomized (randomization to occur at the 3-month follow-up) study comparing the On-X valve on low dose anticoagulation (test group) to concomitant control groups of On-X valves receiving standard Coumadin/aspirin therapy, and also to FDA objective performance criteria (OPC) for heart valve replacement. It is a multicenter ...

Development of symptoms such as heart failure, syncope or angina pectoris is the well-established indication for valve operation in patients with severe aortic stenosis. However, many patients tend to misinterpretate or even ignore symptom onset, and irreversible myocardial dysfunction may occur. Measurement of aortic valve area by transthoracic echocardiography using ...

AORTIC VALVE DISEASE & VENTRICULAR FUNCTION Aortic valve disease is the most common valvular heart disease in Europe (46.4%). The valve can be stenotic (aortic stenosis, AS) or can leak (aortic regurgitation, AR). While mostly elderly patients suffer from AS (a steadily growing group due to the increasing population above ...

The study objective is to verify if a non-invasive remote ischemic preconditioning procedure (blood pressure cuff on the arm) is cardioprotective when applied before an aortic valve replacement surgery.

Cardiovascular diseases remain the major cause of mortality and morbidity in industrialised countries. Their prevalence increases steeply as consequence of the aging of the population in these countries. Curiously, cardiovascular and neurodegenerative diseases share common aging pathological pathways involving abnormal accumulation of insoluble amyloid proteins in the extracellular matrix disrupting ...

This is a single-center, single-blind, all comer, randomized controlled trial. Patients scheduled for isolated aortic valve replacement (AVR) due to aortic stenosis at "Virgen de la Victoria Universitary Hospital", Mlaga, Spain, will be eligible. Ninety-six patients will be randomly assigned to either partial upper sternotomy (ministernotomy, 48 patients) or full ...
