Asymmetric septal hypertrophy Health Dictionary

See HEART, DISEASES OF – Congenital heart disease.... atrial septal defect

A congenital abnormality of the HEART affecting about 260 babies in every 100,000, in which there is a hole in the septum – the dividing wall – between the left and right sides of the heart. The effects of the defect depend upon its size and position. A defect in the wall between the atria (upper chambers of the heart) is called an atrial septal defect, and that between the ventricles, a ventricular septal defect – the most common form (25 per cent of all defects). Both defects allow blood to circulate from the left side of the heart, where pressures are highest, to the right. This abnormal ?ow of blood is described as a ‘shunt’ and the result is that too much blood ?ows into the lungs. PULMONARY HYPERTENSION occurs and, if the shunt is large, heart failure may develop. A small septal defect may not need treatment but a large one will need to be repaired surgically.... septal defect

An inherited defect of the HEART. The septum (partition) separating the two ventricles is pierced by a hole which, if large, results in blood being diverted to the LUNGS at a greater pressure than normal. This may lead to irreversible PULMONARY HYPERTENSION, which early surgical intervention (repair of the septal defect) should prevent. A quarter of patients with VSD have other cardiac defects. Half of the defects seal themselves spontaneously.... ventricular septal defect

The increase in size which takes place in an organ as the result of an increased amount of work demanded of it by the bodily economy. For example, when valvular disease of the heart is present, compensation occurs by an increase in thickness of the heart muscle, and the organ, by beating more powerfully, is able to overtake the strain thrown upon it. Similarly, if one kidney is removed, the other hypertrophies or grows larger to take over the double workload.... hypertrophy

(BPH) The benign buildup in the prostate of “warts” or epithelial neoplasias that can block or interrupt urination, and which are usually concurrent with moderate prostate enlargement. They cause a dull ache on urination, ejaculation, and/or defecation. The diagnosis is medical, since the same subjective conditions can result from cancer of the prostate. BPH is common in men over fifty and can be the result either of diminished production of complete testosterone or poor pelvic circulation. Alcohol, coffee, speed, and antihistamines can all aggravate the problem.... benign prostatic hypertrophy, or hyperplasia

Enlargement of the ventricular chambers of the HEART, a common complication of HYPERTENSION and coronary artery disease (see HEART, DISEASES OF). Treatment is of the underlying conditions and cardiac drugs which facilitate the working of the heart.... ventricular hypertrophy

a primitive reflex that is present from birth but should disappear by six months of age. If the infant is lying on its back and the head is turned to one side, the arm and leg on the side to which the head is turned should straighten, and the arm and leg on the opposite side should bend (the ‘fencer’ position). Persistence of the reflex beyond six months is suggestive of *cerebral palsy.... asymmetric tonic neck reflex
