| intracranial mycotic aneurysm | <radiology> 3% of all intracranial aneurysms; multiple in 20%, source: subacute bacterial endocarditis (65%), acute bacterial endocarditis (9%), menigitis (9%), septic thrombophlebitis (9%), myxoma, location: peripheral to first bifurcation of major vessel (64%), often near the surface of brain (especially over convexities), Note: develops recurrent bleeding more frequently than congenital aneurysms See: mycotic aneurysm (12 Dec 1998) |
|---|---|
| thoracic aortic aneurysm | <radiology> Normal size: 4-5 cm, most aneurysms rupture when more than 10 cm, mean age: 65 years; M:F = 3:1 associated with: hypertension, coronary artery disease, abdominal aortic aneurysm symptoms: substernal, back, shoulder pain (25%), superior vena cava syndrome, dysphagia, stridor, dyspnea, hoarseness see: aortic aneurysm (12 Dec 1998) |
| ectatic aneurysm | An aneurysm in which all the coats of the artery, though stretched, are unruptured. (05 Mar 2000) |
| embolomycotic aneurysm | An obsolete term for an aneurysm caused by an embolism composed of an infected vegetation from a cardiac valve. (05 Mar 2000) |
| traumatic aneurysm | An aneurysm resulting from physical damage to the wall of an artery; usually a false aneurysm or arteriovenous aneurysm. (05 Mar 2000) |
| true aneurysm | Localised dilation of an artery with an expanded lumen lined by stretched remnants of the arterial wall. (05 Mar 2000) |
| tubular aneurysm | The uniform dilation of an artery along a considerable distance. Synonym: cylindroid aneurysm. (05 Mar 2000) |
| false aneurysm | <surgery> Pulsating, encapsulated haematoma in communication with the lumen of a ruptured vessel, ventricular pseudoaneurysm, a cardiac rupture contained and loculated by pericardium, which forms its external wall. An aneurysm whose walls consist of adventitia and periarterial fibrous tissue and haematoma. (05 Mar 2000) |
| fusiform aneurysm | An elongated spindle-shaped dilation of an artery. (05 Mar 2000) |
| aberrant ventricular conduction | Abnormal intraventricular conduction of a supraventricular beat, especially where surrounding beats are normally conducted. Synonym: ventricular aberration. (05 Mar 2000) |
| aortico-left ventricular tunnel | Congenital connection between the aorta above exit of coronary arteries and the left ventricle. (05 Mar 2000) |
| arrhythmias, ventricular | Abnormal rapid heart rhythms (arrhythmias) that originate in the lower chambers of the heart (the ventricles). Ventricular arrhythmias include ventricular tachycardia and ventricular fibrillation. Both are life threatening arrhythmias most commonly associated with heart attacks or scarring of the heart muscle from previous heart attack. (12 Dec 1998) |
| arrhythmogenic right ventricular dysplasia | A congenital cardiomyopathy in which transmural infiltration of adipose tissue results in weakness and aneurysmal bulging of the infundibulum, apex, and posterior basilar region of the right ventricle and leads to ventricular tachycardia arising in the right ventricle. (12 Dec 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) |
| bidirectional ventricular tachycardia | Ventricular tachycardia in which the QRS complexes in the electrocardiogram are alternately mainly positive and mainly negative; many such cases may represent ventricular tachycardia with alternating forms of aberrant ventricular conduction. (05 Mar 2000) |
