Active clinical trials for "Heart Diseases"

This is a pilot study of patients undergoing structural heart disease procedures that utilize TEE and fluoroscopic guidance at the New York University (NYU) Langone Medical Center. Patients in this study will undergo their procedure utilizing the TEE/Angio fusion software prototype. This protocol is primarily intended to ascertain the potential utility of the software prototype in the study population and to provide data and feedback to improve the workflow and algorithms of the prototype. As such, a primary outcome variable and statistical analysis plan have not been identified. However, procedural time, measures of radiation exposure (dose area product, total radiation dose, fluoroscopy time), degree of residual valvular regurgitation or paravalvular regurgitation as applicable, and complications will be recorded.

The SYNTAX III Revolution trial is a randomized diagnostic research study that investigates the use of CT scan and angiogram of the heart to help doctors decide which method is the best to improve blood supply to the heart in patients with complex coronary artery disease. Each patient will undergo an angiogram and CT scan per standard of care. The randomization strategy in this study is not between patients but between two teams of doctors, the so-called "Heart Teams", will be randomized: in the first round, team 1 assesses the angiogram, and team 2 assesses the CT scan. Then they make a decision about which treatment would be the best to treat complex coronary artery disease. In the second round, both teams see the imaging method that they did not see in the first round, and make the decision again. The final decision on the clinical treatment strategy is at the sole discretion of the Heart Team and there are no criteria described in SYNTAXIII Revolution protocol leading influencing this final decision. Hypothesis: Determination of the best treatment strategy for coronary artery disease based on a CT scan will result in similar decisions as based on invasive coronary angiography.

Congenital heart disease with need for early surgery in newborns is associated with an increased incidence in global impairment in development. The causes of these late adverse neurologic outcomes are multifactoral and include both fixed (or patient-specific factors) and modifiable factors. They relate to both the mechanism of central nervous system injury associated with congenital heart disease and its treatment. Measuring cerebral oxygenation is a promising non-invasive way of cerebral monitoring in a neonatal intensive care unit. The importance of cerebral monitoring in neonates with congenital heart problems at risk of developing neurological complications is increasingly recognized. In this way the most vulnerable moments for the newborn brain can be detected and ,if possible, lead to change in (timing of) treatment.

The aim of the study is to evaluate the value of postoperative troponin in the prediction of mid term and long term mortality and morbidity in children with congenital heart disease undergoing cardiac surgery.

Diastolic function is poorly studied in children with congenital heart disease. This is mainly due to the lack of validated techniques. Cardiac MRI offers two advantages compared to echocardiography: 1. accurate measurements of ventricular volumes and mass; 2. tissue characterization. The main advantage of echocardiography is a better temporal resolution which allows the study of short events like early relaxation. Overall there is a lack of studies correlating different echocardiographic and MRI parameters of heart function in pediatric populations with congenital or acquired heart diseases. This study will address specific questions on specific groups of patients that might bring more insight into chamber interaction and cardiac function. This study hypothesizes the following: Atrial enlargement is a marker of chronic increase in filling pressures and 3D echo might be the best method for follow-up. Cardiac remodeling associated with chronic loading results in changes in diastolic properties related to changes in cardiac mass and volume. This is related to changes in cardiac mechanics influencing diastolic parameters. Especially the influence on twisting and untwisting will be studied. Regional myocardial fibrosis and scarring may account for regional systolic and diastolic dysfunction with possible prognostic impact

Cardiac output (CO) is an important hemodynamic variable in the management of critically ill patients. The pulmonary artery catheter (PAC) requires invasive techniques with potential complications and there is increasing interest in less invasive methods of measuring CO. This study is designed to compare CO values from PAC thermodilution (COTD) and ultrasound dilution (COUD).

One of the most important factor that affects the post op complication of the cardiac surgery is systemic inflammation. Valvular heart surgery requires cardiopulmonary bypass and cardioplegic arrest, which can arouse the ischemic/reperfusion injury causing myocardial damage and inflammatory response. These myocardial damage and inflammatory response can cause multi-organ failure or even death.

Differentiating hypertrophic cardiomyopathy (HCM) from hypertensive heart disease (HHD) unavoidably encounters diagnostic challenges especially in patient of suspected HCM with history of hypertension. Diverse and overlapping forms of HCM can often lead to ambiguity when diagnosis is based on a single genetic or morphological index. The investigators have deduced a integrated formula based on cardiac magnetic resonance (CMR) imaging and established a differentiating flow-chart between HCM and HHD, the investigators aim to identify their method in the current multi-center trial.

The complex congenital cardiac malformations are a significant number of different diseases, each having specific natural histories. The interface with pulmonary arterial hypertension (HTAP) is high since the physiology of many of these disorders comprises alterations in pulmonary vasculature. This observatory is a cohort of 400 patients enrolled in 3 years, older than one month, having been informed and have agreed to participate in the study and with congenital heart disease other than patent foramen ovale as well as a diagnosis of pulmonary hypertension confirmed by cardiac catheterization. The main objectives of this report are to know Incidence of congenital heart disease in HTAP France. Describe the natural history of HTAP in a large population of patients Congenital heart disease in France The characteristics of HTAP congenital heart disease Having a cohort study

The six-minute walk test is an established submaximal exercise test. Its role in examination of grown-up patients with congenital heart disease (GUCH) is not studied so far. Objective of this study was a comparison of the 6MWT with other established parameters of functional capacity, in grown-up patients with GUCH.
