Active clinical trials for "Heart Diseases"

There is no study evaluating online exercise training and results in children with pacemakers. This study investigates the effects of group exercise training performed via computer online videoconferencing in pediatric arrhythmia patients with pacemakers. Pediatric arrhythmia patients aged 6-18 years with a pacemaker, stable clinically, and living with at least one parent or caregiver who can support them at home will be included in the study. Eligible patients will be randomly divided into two groups. After the face-to-face evaluation session, those in the intervention group will receive real-time online exercise training for 30 minutes, three days a week, with a peer group of 5-6 people for eight weeks. Physical activity will be monitored for seven days before starting the exercise and seven days after the training is completed. After the first face-to-face evaluation session, patients in the control group and their families will receive a 1-hour disease- and exercise-specific patient education program. Information brochures containing physical activity and exercise recommendations will be given. They will be followed up with weekly phone calls throughout the study period.

This study will evaluate the safety and effectiveness of the Edwards SAPIEN 3/SAPIEN 3 Ultra Transcatheter Heart Valve (THV) compared with clinical surveillance (CS) in asymptomatic patients with severe, calcific aortic stenosis.

The purpose of this study is to further evaluate the safety and effectiveness of the Harmony™ TPV system.

To demonstrate the safety and effectiveness of the Edwards Alterra Adaptive Prestent in conjunction with the Edwards SAPIEN 3 Transcatheter Heart Valve (THV) System in subjects with a dysfunctional right ventricular outflow tract/pulmonary valve (RVOT/PV) who are indicated for treatment of pulmonary regurgitation (PR). Following completion of enrollment, subjects will be eligible for enrollment in the continued access phase of the trial.

The purpose of this investigation is to see if the TRICENTO Valved Stent Graft implant reduces tricuspid regurgitation (TR) and improves the symptoms and quality of life in 15 participants with carcinoid heart disease, and who are not able to have a new valve via a surgical procedure.

Atrial fibrillation (AF) and heart failure (HF) are two common heart conditions that are encountered with an increase in death and suffering. When both these two conditions occur in a patient, the patient's prognosis is poor with a reduced quality of life and impaired heart function. These patients have enlarged hearts, specifically the left ventricle (major pumping chamber), which impairs the heart's pumping capacity, leading to symptoms such as fatigue, shortness of breath from any type of exertion, and swelling, usually of the feet and ankles. In these HF patients who are in AF all of the time, who would otherwise be a suitable candidate for an implantable defibrillator to prevent sudden cardiac death, we would like to determine whether adding pacing of both ventricles will reduce heart size (left ventricular end systolic volume index LVESVi) as measured by ultrasound, which can improve its function and help the heart pump more efficiently. Other studies have shown that adding pacing to both ventricles is of benefit in HF patients with mild to moderate symptoms and have a regular heart rhythm. The Investigators now want to explore if this therapy will benefit those patients with a permanent irregular heart rhythm (AF).

The purpose of this study is to implement and externally validate an inpatient ML algorithm that combines pulse oximetry features for critical congenital heart disease (CCHD) screening.

The purpose if this pilot study is to determine if a perioperative infusion of 0.2% ropivacaine via bilateral T3 paravertebral catheters can decrease the incidence of new onset atrial fibrillation following primary CABG and/or valve surgery and compare a number of secondary outcomes.

Among patients with stable ischemic heart disease who are referred for coronary angiography, a substantial proportion have non-obstructive coronary artery disease (CAD). Ischemia based on symptoms or stress testing may be due to coronary microvascular dysfunction in up to 40% of these patients. However, the mechanisms and optimal treatment of coronary microvascular dysfunction are unknown. Aberrant platelet activity and inflammation have been hypothesized as mechanisms of microvascular dysfunction. Investigators plan to evaluate association between platelet activity, inflammation, and coronary microvascular dysfunction in stable women referred for coronary angiography, and to identify non-invasive correlates of coronary microvascular dysfunction in these patients.

The primary objective in this study is to investigate if vein grafts harvested and implanted with the non-touch technique are superior to conventional vein graft technique with respect to mid-term patency, in patients undergoing CABG surgery.
