We present here a simplified method to perform Bidirectional Glenn’s Cavo-Pulmonary Shunt (BDG) in which we use no cardiopulmonary bypass (CPB) nor an intra-operative temporary shunt, sometimes used on the belief that it lessens the developed intra-venous congestion and pressure in the upper torso, intra-operatively. Our approach springs from the idea that acute intra-venous congestion, resulting from the application of vascular cross-clamp on the superior vena cava (SVC) during operation, is being vented through abundant and numerous anatomic venous anastomoses between the SVC system and the inferior vena cava (IVC) system. It also springs from the conception that the brain of patients with low arterial blood O2-saturation tolerates cerebral hypoxia better than the normally functioning brain. Such hypoxia may ensue from the transient low cerebral arterial blood flow, resulting in turn from the temporary intravenous cerebral congestion (and related raised pressure) following SVC clamping.

Prenatal detection of congenital heart disease is possible from the 16th week of pregnancy. the ideal time being the Midtrimester ,when the most cardiac abnormalities can be detected ,where all routine cross sectional views are easily obtainable. To evaluate the detection and accuracy of fetal echocardiography for congenital heart defects among high risk pregnancies.
The role of the inflammatory process in atherosclerosis and its development has been confirmed, as many inflammatory factors intervene in the vasculitis process, which leads to damage to the endothelium, which is the early event in the process of atherosclerosis.
OFF pump coronary artery by pass surgery when It is done by experienced surgeons and with new cardiac stabilizer which allows to perform a complete revascularization with a good results. In additionally OFF PUMP decrease the morbidity coronary artery by pass such as stroke , renal failure and need for blood transfuration.
Heart disease is the leading cause of death in the world over the past 10 years. Researchers have been using several data mining techniques to help health care professionals in the diagnosis of heart disease. Decision Tree is one of the successful d ata mining techniques used. However, most research has applied J4.8 Decision Tree, based on Gain Ratio and binary discretization. Gini Index and Information Gain are two other successful types of Decision Trees that are less used in the diagnosis of heart disease. Also other discretization techniques, voting method, and reduced error pruning are known to produce more accurate Decision Trees. This research investigates applying a range of techniques to different types of Decision Trees seeking better performance in heart disease diagnosis. A widely used benchmark data set is used in this research. To evaluate the performance of the alternative Decision Trees the sensitivity, specificity, and accuracy are calculated. The research proposes a model that outperforms J4.8 Decision Tree and Bagging algorithm in the diagnosis of heart disease patients.
Background: longitudinal and radial systolic function are weakened by cardiac diseases and longitudinal one is weakened first. Assessment of left ventricular LV systolic function is important in management and prognosis of cardiac diseases. Mitral annular displacement MAD is used to assess LV longitudinal and global systolic function. Objectives: To validate the accuracy of MAD assessed by Doppler tissue imaging DTI and m-mode echocardiography MME as a surrogate for determination of LV systolic function in pationts with ischemic heart disease and/or heart failure, and maybe easy and fast way instead of conventional echocardiography assessment of LV function. This way permits to study the function of LV longitudinal cardiac fibers function while the conventional ways of echocardiography assesses the circumferential shortening. Patients and methods: We studied a series of 96 patients (men and women) with (ischemic heart diseases,heart failure) divided into three age groups and compared with another 59 healthy age matched volunteers as a control group. We selected subjects from AL ASSAD hospital /LATAKIA over the year 2014. A medical history, whole medical examination, ECG, conventional echocardiography were made to each subject. Ejection fraction EF of LV, Doppler recording of the mitral inflow, MME and pulse wave Doppler tissue imaging PW DTI data (from each four sites of mitral annulus, anterior, septal, lateral and inferior) were obtained. Mean peak systolic velocity (S wave), mean annular early diastolic velocity (e') by PW DTI and mean mitral annular displacement (MAD) by MME were calculated by averaging of values measured at each annular site. Results: MAD correlate well with LV EF, mean MAD < 11.275 mm determined by MME has 85% sensitivity and 87.8% specificity and 85.8% accuracy for detection of LV EF < 50%, Mad was low in patients with infarctions and lower in pationts with heart failure. Conclusion: Mean MAD connect with a positive relationship with LV EF and can detect the abnormal systolic motion on the long axis. That means the ability to detect the ischemia in early stages.
