Active clinical trials for "Heart Valve Diseases"

This study aims to explore the feasibility of a novel, patient-specific algorithm for adjusting warfarin doses during chronic anticoagulation therapy. Specifically investigators are interested in determining whether patients can use this algorithm to assume responsibility for managing their own warfarin therapy including making independent decisions about their warfarin dose and when to retest their next international normalized ratio (INR) test based on the result of their current INR result obtained using a point-of-care INR monitor.

The current management of tricuspid regurgitation (TR) is either conservative (by medication) or by surgery, usually in concomitant with other valves repair or replacement. TR can worsen or appear late after successful mitral valve surgery which portends a poor prognosis. However, standard surgical approaches requiring cardiopulmonary bypass and especially second surgery have an excessive risks. Thus many patients are denied surgery because of unfavorable risk-benefit balance. Therefore there is a need for novel devices enabling interventional cardiologists and cardiothoracic surgeons to perform tricuspid annuloplasty by transcatheter methods. Cardioband replicates established surgical techniques (e.g., annuloplasty) using transfemoral approach, without sutures and with adjusted on the beating heart. Similar to the approved indication for mitral annuloplasty. The Cardioband System is expected to allow for treatment of patients that would otherwise not undergo Tricuspid valve repair due to the invasiveness of current techniques.

To evaluate the safety and clinical efficacy of left atrial appendage in the prevention of thrombus in patients with valvular heart disease, to improve the product according to clinical conditions, to achieve clinically accurate treatment, and to establish the heart valve, the usefulness and universality of Warfarin's anticoagulant model were verified by the specimen library

This observational study aims to assess the performance of the software called ausculto™. ausculto™ is a collection of computer algorithms that intend to analyse heart sounds recorded from the built-in microphone of a smartphone for abnormal sounds. Participants will have their heart sounds recorded during their regular clinic appointment after consenting to participate in this study. Researchers will manually annotate the recorded heart sounds to create a database for use in future training and testing of artificial intelligence (AI) intended for medical uses.

This is a single-center, double-blind, randomized controlled trial (RCT) comparing two groups of application of topical dose of tranexamic acid (TxA) versus placebo in patients undergoing coronary artery bypass graft (CABG), off pump coronary bypass graft cardiac surgery (OPCAB), and adult heart valve surgery. The primary outcomes of this study comprised of two parameters; post operative bleeding and blood product transfusion. The primary outcomes were assessed during the operation, until 48-hour post operative.

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", Málaga, Spain, will be eligible. Ninety-six patients will be randomly assigned to either partial upper sternotomy (ministernotomy, 48 patients) or full sternotomy AVR (48 patients). Sample size was determined for an Alpha error of 0.05,and Beta error of 0.1 for a power of 90% in detecting 0.10 difference points in quality of life EQ-5D-5L-index or 10 points in EQ-5D-5L-Visual Analogic Scale (QOL).

The purpose of this clinical study is to obtain human clinical data that demonstrates that the size 23mm Carpentier-Edwards PERIMOUNT Magna mitral pericardial valve, model 7000TFX, is a safe and effective replacement heart valve.

To further evaluate the long term clinical safety and effectiveness of the Trifecta valve

The aim of our study was to evaluate the significance of monitoring anesthetic depth for the conduct of anesthesia and the early postoperative period in patients subjected to surgical correction of combined valvular disorders.
