Filter by:The main objective of this study is to evaluate the reproducibility and accuracy of TTE-3DKBR in assessing RV volume and EF compared to the reference method of CMR in a group of ACHD patients with known moderate or severe PR after ToF repair. As part of the validation study, the reproducibility of the TTE-3DKBR in assessing RV volume and EF will also be tested in a group of healthy adult volunteers. Additionally, TTE-3DKBR evaluation will be compared in both groups to the conventional 2D echocardiography measurements used in routine clinical practice, such as tricuspid annular plane systolic excursion (TAPSE), tissue Doppler imaging (TDI), fractional area change (FAC), and global longitudinal strain (GLS). Another objective of the study is also to evaluate the effects of chronic RV volume overload with an interval of one-year follow-up using TTE-3DKBR and compare it with the conventional non-geometric echocardiography measurements, particularly with GLS. The study will end when the required number of patients have been enrolled and when the last subject undergoes the research dataset acquisition. The study may be terminated prematurely if it becomes apparent that the recruitment target cannot be met within the projected recruitment phase.
- To predict vulnerable patients for aortic root dilatation in TOF patients using CT as a reliable imaging modality, thus aiding early intervention, and identifying those who will require strict follow-up. - To assess the prevalence of TOF patients who developed aortic root dilatation, and those who were complicated with dissection, AR, and aneurysm, through collecting data from a large center (Aswan Heart Centre). - To investigate the relationship between age at repair and the diameter of aortic root.
Patient with Tetralogy of Fallot need live-long surveillance after initial operative correction (rTOF). MRI is an established and important component of the standardized follow-up in this patient population. A new score will be used to summarize the multitude of MRI-based parameters into a single number. Individual modificators are assigned to the components of the score. The value of each modificatory will be determined as a result of this feasibility trial. This new compound score is designed to anticipate any deterioration of cardiac function, arrhythmias or sudden cardiac death. This feasibility study is the first step to establish this score and find initial values for the modifies that are assigned to the more than 40 biomarkers from MRI, clinical examinations and serum parameters that are included in this new score.
The objective of this work is to estimate the correlation between the electrical activation of the VD measured by the CARTO electrophysiological mapping system and the mechanical activation of the VD measured by 3D echocardiography and 3D speckle-tracking. Our hypothesis is that there is a strong correlation between electrical activation and mechanical activation in patients with an operated Fallot tetralogy.
Evaluation of cardiac and extra cardiac vascular defects associated with Tetralogy of fallot in pediatric patients, regarding frequency and types of anomalies with assesment of multidetector computed tomography diagnostic value.
The ACHDi Registry study will create a foundational database for adult congenital heart disease interventions. This Pan-Canadian Registry will collect clinical and patient-reported information that will enable the evaluation of care processes and outcomes in five most common ACHDi interventions by enabling prospective and retrospective registry-based studies to answer important clinical practice and policy-relevant questions.
To compare of mid-term results of total correction of tetralogy of fallot between preservation of pulmonary valve and trans-annular patching , thus avoiding PV regurgitation during TOF repair , this will determine the value of this procedure over trans-annular patching regarding to right ventricular performance.
Congenital malformations correspond to defects in organ morphogenesis identifiable at birth or intrauterine life, affecting 2-3% of births. Inside of these malformations, Congenital Heart Disease corresponds, in particular, to structural defects of the heart or major blood vessels thereof may or may not be associated with other types of syndromes.The resolution is usually surgical. Also, these patients present a decrease in physical fitness, psychological imbalance, lower quality of life and risk significant morbidity and mortality from respiratory infections among other problems. This can have severe consequences for health in the medium and long term. The habits acquired during childhood and adolescence are determinant for the adult life, being relevant levels of activity and physical condition, especially in children with pathologies. In this way, it is vital to know from childhood parameters that indicate the baseline state of these patients according to the levels of physical activity, exercise capacity, nutritional status and quality of life. These will be key indicators to take into account in the future, to adapt rehabilitation plans that will reduce the effects of their condition. The objective of this protocol is To characterize the levels of Activity, and Physical Capacity of children with congenital heart disease regularly treated at the Cardiovascular Center of Dr. Luis Hospital Calvo Mackenna, compared to healthy children matched by age and sex.
