The classes of anomalous diffusions are classified as follows: α < 1: subdiffusion. This can happen due to crowding or walls. For example, a random walker in a crowded room, or in a maze, is able to move as usual for small random steps, but cannot take large random steps, creating subdiffusion.
Chest x-ray of a five-year-old girl with Scimitar syndrome. The heart (blue outline) is shifted into the right half of the chest, and the anomalous pulmonary venous return (red) has a shape reminiscent of a Scimitar. The diagnosis is made by transthoracic or transesophageal echocardiography [citation needed] and selective pulmonary angiography. [5]
Syndrome Cause cardiac signs and symptoms Other symptoms or organs affected Notes 1q21.1 deletion syndrome: genetic (Chromosome 1)Cardiovascular anomalies are present in 30% of the cases (for example anomalous origin of the coronary artery in "Class II-deletion")
A Blalock-Taussig operation performed by Dr. Alfred Blalock in 1947 helped to significantly improve the condition of the patient. Before the operation, the patient was diagnosed to have isolated levocardia, pulmonary stenosis, overriding aorta with a right aortic arch and anomalous return of the pulmonary and systemic circulations.
It can provide direct visualisation of the anomalous coronary artery and other associated structural abnormalities, and it can also assess myocardial function. The use of pulse and color-flow doppler can sometimes visualise reversal flow in the pulmonic artery.
In a normal heart beat rhythm, the SA node usually suppresses the ectopic pacemaker activity due to the higher impulse rate of the SA node. However, in the instance of either a malfunctioning SA node or an ectopic focus bearing an intrinsic rate superior to SA node rate, ectopic pacemaker activity may take over the natural heart rhythm.

Total anomalous pulmonary venous connection, also known as total anomalous pulmonary venous return, is a rare cyanotic congenital heart defect in which the pulmonary veins drain into the right side of the heart instead of the left, as is usually seen. This can happen within the heart (intracardiac) where it drains into the coronary sinus or ...
Atherosclerosis (heart disease) may be related to K ir channels. The loss of K ir currents in endothelial cells is one of the first known indicators of atherogenesis (the beginning of heart disease). Thyrotoxic hypokalaemic periodic paralysis has been linked to altered K ir 2.6 function. [19] EAST/SeSAME syndrome is caused by mutations in ...
