Polycystic liver disease (PLD or PCLD) is a rare condition that causes cysts -- fluid-filled sacs -- to grow throughout the liver. A normal liver has a smooth, uniform appearance. A polycystic liver can look like a cluster of very large grapes.
Tendons are thick cords that join your muscles to your bones. When these tendons become irritated or inflamed, it is called tendinitis. This condition causes acute pain and tenderness, making it difficult to move the affected joint. Read more
The term hypoplastic left heart syndrome (HLHS), initially proposed by Noonan and Nadas, [1] describes a spectrum of cardiac abnormalities characterized by marked hypoplasia of the left ventricle and ascending aorta. This is the same disorder characterized as hypoplasia of the aortic tract complex by Lev. [2] The aortic and mitral valves are atretic, hypoplastic, or stenotic. A patent foramen ovale or an atrial septal defect is usually present. The ventricular septum is usually intact. A large patent ductus arteriosus supplies blood to the systemic circulation. Systemic arterial desaturation may be present because of complete mixing of pulmonary and systemic venous blood in the right atrium. Coarctation of the aorta is also commonly present. See the images below.
Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs).
Cells may have slender extensions of the cell membrane to form cilia or the smaller extensions called microvilli. The microscopic microvilli effectively increase the surface area of the cell and are useful for absorption and secretion functions. A dramatic example is the human small intestine. The tissue has small fingerlike extensions called villi which are collections of cells, and those cells have many microvilli to even further increase the available surface area for the digestion process. According to Audesirk & Audesirk, this can give an effective surface area of about 250 square meters for absorption.
Cardiac cath is performed to find out if you have disease of the heart muscle, valves or coronary (heart) arteries. During the procedure, the pressure and blood flow in your heart can be measured. Coronary angiography is done during cardiac catheterization.
The term trisomy is used to describe the presence of three chromosomes, rather than the usual matched pair of chromosomes. For example, if a baby is born with three #21 chromosomes, rather than the usual pair, then the baby would be said to have "trisomy 21." Trisomy 21 is also known as Down syndrome. Other examples of trisomy include syndromes like trisomy 18 and trisomy 13. Again, trisomy 18 or trisomy 13 simply means the child has three copies of the #18 chromosome (or of the #13 chromosome) present in each cell of the body, rather than the usual pair.
Migraine headaches are recurrent throbbing or pulsatile headaches often associated with a prodrome, nausea, vomiting, photophobia, and phonophobia. When they occur, the prodromes are characterized by visual scintillations, scotomas, dizziness, or tinnitus
The procedure is used most often to treat a condition called supraventricular tachycardia, or SVT, which occurs because of abnormal conduction fibers in the heart. Catheter ablation is also used to help control other heart rhythm problems such as atrial flutter and atrial fibrillation.
