ventricular

Of or relating to a ventricle or ventriculus.

Pertaining to a ventricle.

• v. assist device — a circulatory support device consisting of a pump with afferent and efferent conduits attached to the left ventricular apex and the ascending aorta, respectively, each conduit containing a porcine valve to ensure unidirectional blood flow; the pump rests on the external chest wall and is connected to an external pneumatic power source and control circuit.
• v. asystole — see asystole.
• v. bands — folds of mucosa, parallel and craniolateral to the vocal cords. Called also false vocal cords, vestibular folds.
• double right v. outlet — a cardiac anomaly rarely seen in animals in which both the aorta and pulmonary artery arise from the right ventricle and there is a defect in the ventricular septum.
• excessive v. moderator bands — a rare syndrome of cardiomyopathy in cats caused by an excessive number of moderator bands in the left ventricle, extending from the papillary muscles to the ventricular septum.
• v. extrasystoles — see ventricular extrasystole.
• v. fibrillation — see ventricular fibrillation.
• v. function curve — see starling curves.
• v. hypertrophy — see ventricular hypertrophy.
• v. outflow obstruction — flow of blood from the ventricles is impaired by lesions or congenital abnormalities in the outflow tract. This is usually associated with hypertrophy of the ventricle and can be demonstrated with echocardiography or contract radiography. Left outflow obstruction occurs with stenosis and other anomalies of the aorta; right outflow obstruction occurs with pulmonic stenosis, pulmonic insufficiency, tetralogy of Fallot, and double-chambered right ventricle.
• v. premature contraction (VPC) — see premature heartbeats.
• v. rupture — due to focal weakness causes sudden death due to cardiac tamponade.
• v. septal defect — a congenital heart defect in which there is persistent patency of the ventricular septum in either the muscular or fibrous portion most often due to failure of the bulbar septum to completely close the interventricular foramen. The defect permits flow of blood directly from one ventricle to the other, bypassing the pulmonary circulation and producing varying degrees of cyanosis because of oxygen deficiency. Its clinical characteristics also include a systolic murmur and a palpable thrill on both sides of the chest, dyspnea and poor exercise tolerance. The occurrence is sporadic except that it is inherited in goats and dogs.
• v. septum — the muscular wall between the ventricles. A small section, between the aortic vestibule and the right atrium, is membranous. Failure of the septum to close completely during fetal growth causes a septal or subaortic defect.
• v. shortening fraction — in echocardiography, the percentage change in diameter from diastole to systole. Calculated from the internal systolic and diastolic dimensions. It is a measure of mycocardial function.
• v. slice method — a method for examination of fixed heart by cutting it into 0.5 inch thick slices, perpendicular to the plane of the ventricular septum, from apex to base. Useful in examination of myocardial lesions and cardiomyopathy.
• v. tachycardia — is manifested by a high heart rate with or without arrhythmia. In both cases there is severe cardiac disease and often acute heart failure.
