Active clinical trials for "Heart Diseases"

The purpose of the study is to determine whether the neurodevelopmental outcome and in particular executive functions in 9 to 14 year old school children with congenital heart disease who underwent cardiopulmonary bypass surgery during their first three months of life is impaired in comparison to healthy children at same age. Executive functions are higher order cognitive functions and critical for school success.

The purpose of this study is to assess coagulation and platelet function in children with congenital heart disease, measured with a bedside device (thromboelastometry and impedance aggregometry). The investigators also aim to determine if this device detect post-cardiopulmonary bypass clotting derangements and may help to manage bleeding in this 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.

Cross-sectional study of a national cohort of adolescents with univentricular congenital heart defects and Fontan type palliation.

After cardiac surgery, patients' follow-up after discharge is a major public health issue. Since the main complications occur mostly during the first extra-hospital month, a follow-up period becomes necessary as the average duration of hospitalization tends to decrease. The resumption of normal physical activity is rarely transmitted and when complications arise, the healthcare team is most often informed late. An electronic wristband is worn by the patient during the day, between the day of discharge from the hospital (D0) and the end of the second extra-hospital month (D60). The data recorded by the wristband include : bracelet ID, date, time and number of steps per day. The primary objective of the study is to measure the resumption of physical activity after elective cardiac surgery. This objective will be quantified by the number of daily footsteps. A secondary objective is to determine perioperative predictors of the physical resumption.

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.

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.

The aim of the Cork and Kerry Study Phase II (Mitchelstown cohort recruited 2010-11) is to provide an updated profile of glucose tolerance status, cardiovascular health and their related factors in an Irish adult general population sample and to compare the findings with those obtained during baseline assessment of Phase I of the Cork and Kerry study (1998) and the rescreen (2008).

Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. The purpose of the FAVOR II China study is to evaluate the diagnostic accuracy of on-line QFR with FFR as the reference standard. The secondary purpose is to compare the diagnostic accuracies between online QFR and online QCA, with FFR as the reference standard.
