| billowing mitral valve syndrome | <syndrome> The clinical constellation of findings with or without symptoms due to prolapse of the mitral valve: a nonejection systolic click accentuated in the standing posture, sometimes multiple, sometimes with mitral regurgitation occurring relatively late in systole, and accompanied by echocardiographic evidence of the mitral valve prolapse, usually with thickened leaflets of the valve. Symptoms are non-specific and may include vague chest pains and dyspnea on exertion. Synonym: billowing mitral valve syndrome. (05 Mar 2000) |

| valve | A device that controls the flow of a fluid through a pipe. One shell of a double shelled mollusc such as a clam or oyster. In botany terminology, a portion of an organ that has fragmented, of a capsule, the teeth like portions into which the dehiscing part of the pericarp splits at maturity. (09 Oct 1997) |
| valve of coronary sinus | A delicate fold of endocardium at the opening of the coronary sinus into the right atrium. Synonym: valvula sinus coronarii, coronary valve, thebesian valve. (05 Mar 2000) |
| valve of foramen ovale | A fold projecting into the left atrium from the margin of the foramen ovale in the foetus; when, with beginning inspiration, the blood pressure within the left atrium increases, the valve closes and its edges become adherent to the margin of the foramen ovale, occluding it. Synonym: valvula foraminis ovalis, falx septi, valve of oval foramen. (05 Mar 2000) |
| valve of inferior vena cava | An endocardial fold extending from the anterior inferior margin of the inferior vena cava to the anterior part of the limbus fossa ovalis. Synonym: valvula venae cavae inferioris, caval valve, eustachian valve, sylvian valve. (05 Mar 2000) |
| valve of navicular fossa | A fold of mucous membrane sometimes found in the root of the navicular fossa of the urethra. Synonym: valvula fossae navicularis, Guerin's fold, Guerin's valve. (05 Mar 2000) |
| valve of oval foramen | A fold projecting into the left atrium from the margin of the foramen ovale in the foetus; when, with beginning inspiration, the blood pressure within the left atrium increases, the valve closes and its edges become adherent to the margin of the foramen ovale, occluding it. Synonym: valvula foraminis ovalis, falx septi, valve of oval foramen. (05 Mar 2000) |
| valve of pulmonary trunk | <anatomy, cardiology> The heart valve that divides the right ventricle and the pulmonary artery. The pulmonic valve opens when the right ventricle contracts allowing blood to flow into the pulmonary artery. The pulmonic valve on closure prohibits the backwash of unoxygenated blood into the right ventricle. The pulmonic valve has 3 valve cusps. (27 Sep 1997) |
| valve of Varolius | The bilabial prominence of the terminal ileum into the large intestine at the caecocolic junction as seen in cadavers; in the living individual it appears as a truncated cone with a star-shaped orifice. Synonym: valva ileocaecalis, Bauhin's valve, ileocaecal eminence, ileocolic valve, Tulp's valve, Tulpius' valve, valve of Varolius. (05 Mar 2000) |
| valve of vermiform appendix | A fold of mucous membrane, simulating a valve, sometimes found at the origin of the vermiform appendix. Synonym: Gerlach's valve, valvula processus vermiformis. (05 Mar 2000) |
| valve of Vieussens | A prominent valve in the great cardiac vein where it turns around the obtuse margin to become the coronary sinus. (05 Mar 2000) |
