97
Q

coarctation of the aorta

A

a congenital heart defect characterized by a localized narrowing of the aorta, which results in increased blood pressure in the upper extremities (area proximal to the defect) and decreased blood pressure in the lower extremities (area distal to the defect).

98
Q

patent ductus arteriosus

A

an abnormal opening between the pulmonary artery and the aorta caused by failure of the fetal ductus arteriosus to close after birth. This defect is seen primarily in premature infants.

99
Q

tetralogy of Fallot

A

a congenital heart anomaly that consists of four defects: pulmonary stenosis, interventricular septal defect, dextroposition (shifting to the right) of the aorta so that it receives blood from both ventricles, and hypertrophy of the right ventricle; named for the French physician, Etienne Fallot, who first described the condition.

100
Q

106
Q

angiography

A

X-ray visualization of the internal anatomy of the heart and blood vessels after introducing a radiopaque substance (contrast medium) that promotes the imaging (makes them visible) of internal structures that are otherwise difficult to see on X-ray film. This substance is injected into an artery or a vein.

107
Q

cardiac catheterization

A

a diagnositc procedure in which a catheter (a hollow, flexible tube) is introduced into a large vein or artery (usually of an arm or a leg) and then threaded through the circulatory system to the heart. It is used to obtain detailed information about the structure and function of the heart chambers, valves, and the great vessels.
