| sector | 1. <geometry> A part of a circle comprehended between two radii and the included arc. 2. A mathematical instrument, consisting of two rulers connected at one end by a joint, each arm marked with several scales, as of equal parts, chords, sines, tangents, etc, one scale of each kind on each arm, and all on lines radiating from the common center of motion. The sector is used for plotting, etc, to any scale. 3. An astronomical instrument, the limb of which embraces a small portion only of a circle, used for measuring differences of declination too great for the compass of a micrometer. When it is used for measuring zenith distances of stars, it is called a zenith sector. Dip sector, an instrument used for measuring the dip of the horizon. Sector of a sphere, or Spherical sector, the solid generated by the revolution of the sector of a circle about one of its radii, or, more rarely, about any straight line drawn in the plane of the sector through its vertex. Origin: L, properly, a cutter, fr. Secare, sectum, to cut: cf. F. Secteur. See Section. Source: Websters Dictionary (01 Mar 1998) |

Disturbed blood clotting can be manifested by: easy bruising, bleeding gums, nosebleeds, abnormal vaginal bleeding, rectal bleeding, skin rash, vomiting blood, coughing up blood or blood in the urine. A measure of bleeding time and coagulation profile will be part of the evaluation. (29 Dec 1997) |

| aortopulmonary septal defect | A congenital anomaly in which there is abnormal communication between the ascending aorta and pulmonary artery just above the semilunar valves. (12 Dec 1998) |
| atrial septal defect | <cardiology> An inherited condition where there is nonclosure of the foramen ovale at birth, resulting in congenital heart disease. Usually asymptomatic until the third or fourth decades of life. Symptoms include exertional shortness of breath, fatigue and palpitations. Acronym: ASD (12 Jan 1998) |
| atrial ventricular canal defect | A defect caused by deficient or absent septal tissue immediately above and below the normal level of the atrioventricular valves, including the region normally occupied by the A-V septum in hearts with two ventricles. The A-V valves are abnormal to a varying degree. (05 Mar 2000) |
| birth defect | Defect present at birth; sometimes referred to as congenital defect. (05 Mar 2000) |
| ventricular septal defect | <cardiology, embryology> A congenital heart defect where an abnormal opening exists in the ventricular septum. Blood flows from the higher pressure left ventricle (through the defect) into the right ventricle. (12 Jan 1998) |
| Gerbode defect | <cardiology, embryology> A defect in the interventricular portion of the membranous septum, associated with a communication between the right ventricle and the right atrium through an abnormality in the tricuspid valve. (05 Mar 2000) |
