Active clinical trials for "Heart Diseases"

Evaluation of coronary artery vessel wall healing at different time points in patients undergoing implantion of bioresorbable vascular scaffold by using intravascular imaging. In addition long-term clinical follow-ups are planned for all patients treated with Absorb in the institution

This project aims to assess the ability of cardiac imaging (cardiac MRI and Doppler-echocardiography) post-processing tools to predict a combined end-point of intraventricular thrombosis, silent brain infarcts, clinical stroke and peripheral arterial embolism in patients with first acute myocardial infarction and ventricular dysfunction.

This is a observational、multicenter, prospective cohort study for adults with significant VHD. The purposes of this study were to evaluate the etiology、clinical characteristics、treatment modalities, and outcomes of patients with VHD；also to set up registration system of adult VHD in China, to build a database of Chinese adult VHD, to establish a web-based international standard data acquisition system for VHD and a multicenter clinical research platform. The results of the study will provide a basis for the future national health policy for prevention and treatment of adult VHD.

Congenital heart disease (CHD) is the most common congenital malformations. The right ventricle in the sub-aortic position, or "systemic right ventricle" is one of these complex cardiac diseases. Several studies show that adults with CHD and especially systemic right ventricle have reduced exercise capacity. In addition, studies have shown that there is a correlation between alteration of aerobic physical capacity and alteration of right ventricular systolic function. Understanding and assessing the determinants of the physical capacity of patients with systemic right ventricles and evaluating their quality of life could allows us to improve their therapeutic management and also to expand patient indications to a program cardiac rehabilitation. This can benefit them on their exercise capacity, their tolerance to exercise and their quality of life. The aim is to study the correlation between the quality of life and the aerobic physical fitness of patients with a systemic right ventricle and to determine the clinical and paraclinical parameters that have an impact on the aerobic physical fitness of these patients. The quality of life of patients with a systemic right ventricle will be compared to that of the general population.

This research study is to determine the risk factors for acquired heart disease, in adults with congenital heart disease. This knowledge is important to develop and target ways to prevent or delay the onset of acquired heart disease in adults with congenital heart disease.

Cardiac denervation is inherent to the arterial switch (ASO) technique for the repair of transposition of the great arteries (TGA) and the long term reinnervation process has not been studied. We sought to describe the reinnervation status of adult patients long after the ASO, to identify areas of myocardial perfusion/innervation mismatch and to assess the relation of innervation status and exercise capacity.

In which CHD patients with high risk of CV complications are different doses of LIPRIMAR used? For this purpose, data on hyperlipidemia will be elicited over and above the basic nosographic and demographic data, concomitant diseases and cardiovascular risk factor.

This is a research study to determine patient preferences between two different diagnostic tests; a CT angiogram (CTA) and a catheter angiogram, both of which are used at the University to screen for and detect heart disease.

The primary goal of this registry is to collect data regarding the use of the ClearWay RX Local Therapeutic Infusion Catheter for all indications.

The purpose of this study is to determine whether children and adolescents 8-18 years of age with HLHS and related lesions who have undergone stage I palliation during infancy using an allograft patch demonstrate continued evidence of HLA antibody formation.
