| DOLV | Double Outlet Left Ventricle |
micronucleus
| double outlet right ventricle | <cardiology, embryology> Incomplete transposition of the great vessels in which both the aorta and the pulmonary artery arise from the right ventricle, often associated with a subaortic ventricular septal defect. (12 Dec 1998) |
|---|---|
| outlet | An exit or opening of a passageway. (05 Mar 2000) |

| thoracic outlet syndrome | <syndrome> Condition due to compromise of blood vessels or nerve fibres between the armpit (axilla) and base of the neck. (12 Dec 1998) |
| true neurogenic thoracic outlet syndrome | <syndrome> Very chronic axon loss brachial plexopathy, caused by compromise of the lower trunk fibres by a congenital band extending from a rudimentary cervical rib to the first thoracic rib; rare disorder, found mostly in young to middle-aged women, that presents with unilateral hand wasting and weakness, particularly involving the lateral thenar eminence; sometimes accompanied by intermittent discomfort along the medial forearm and hand. Synonym: cervical rib and band syndrome, classic cervical rib syndrome. (05 Mar 2000) |
| Baudelocque's diameter | The distance in a straight line between the depression under the last spinous process of the lumbar vertebrae and the upper edge of the pubic symphysis. Synonym: Baudelocque's diameter, external conjugate diameter. (05 Mar 2000) |
