Ebstein Anamoly Ebstein anomaly is a congenital heart defect in which the septal leaflet of the tricuspid valve is displaced towards the apex of the right ventricle of the heart.Tricuspid valve malformed and displaced downwards with atrialization of right ventricle and florid tricuspid incompetence. Right ventricular cavity is small, and there is interitrial communication through […]
Ventricular Septal Defect (VSD) A ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart.The ventricular septum consists of an inferior muscular and superior membranous portion and is extensively innervated with conducting cardiomyocytes.The membranous portion, which is close to the atrioventricular node, is […]
Ischemic Heart Disease (IHD) Ischemic heart disease (IHD), is the most common type of heart disease and cause of heart attacks.The disease is caused by plaque building up along the inner walls of the arteries of the heart, which narrows the arteries and reduces blood flow to the heart. While the symptoms and signs of […]
TAPVC Total Anomalous Pulmonary Venous Connection Total anomalous pulmonary venous connection (TAPVC) consists of an abnormality of blood flow in which all 4 pulmonary veins drain into systemic veins or the right atrium with or without pulmonary venous obstruction. Systemic and pulmonary venous blood mix in the right atrium. An atrial defect or foramen ovale (part […]
TAPVD Total Anomalous Pulmonary Venous Drainage The Pulmonary Veins, which carry blood back to the heart after it has circulated through the lungs, are not connected to the left atrium.Instead they are connected to one of the veins from the main circulation so that the blood returning from the lungs drains back to the right […]
Transposition of Great Vessels Transposition of great vessels (TGV) is a group of congenital heart defects involving an abnormal spatial arrangement of any of the great vessels: superior and/or inferior venae cavae, pulmonary artery, pulmonary veins, and aorta. Congenital heart diseases involving only the primary arteries (pulmonary artery and aorta) belong to a sub-group called […]
