ventricular

 [ven-trik´u-ler]
pertaining to a ventricle.
ventricular septal defect a congenital heart defect in which the opening in the ventricular septum (normal in the fetus) persists after birth, in either the muscular or fibrous portion, most often due to failure of the bulbar septum to completely close the interventricular foramen. This permits flow of blood directly from one ventricle to the other, resulting in bypassing of the pulmonary circulation and varying degrees of cyanosis. Defective valves affecting the flow of blood to and from the heart may also be present.
Abnormal communication between the ventricles in ventricular septal defect. From Dorland's, 2000.

ventricular

pertaining to a ventricle.

ventricular 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.
ventricular asystole
ventricular bands
folds of mucosa, parallel and craniolateral to the vocal cords. Called also false vocal cords, vestibular folds.
double right ventricular 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 ventricular 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.
ventricular extrasystoles
see ventricular extrasystole.
ventricular fibrillation
see ventricular fibrillation.
ventricular function curve
ventricular hypertrophy
see ventricular hypertrophy.
ventricular 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.
ventricular premature contraction (VPC)
see premature heartbeats.
ventricular rupture
due to focal weakness causes sudden death due to cardiac tamponade.
ventricular 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.
ventricular 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.
ventricular 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.
ventricular 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.
ventricular 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.

9) Several published reports suggest association of LVNC with poor left ventricular function, a high incidence of ventricular arrhythmias and systemic thromboembolism.

While confronting a patient in whom the DDD pacemaker interrogation shows nearly 100% ventricular sensing, but electrocardiographic monitoring shows ventricular pacing, the most important probabilities are: a) Dislodgement of the atrial lead into the ventricle and ventricular capture by it; b) Inappropriate connection of the leads to the generator (atrial lead being connected to the ventricular channel of the generator and vice versa).
Left ventricular hypertrophy was defined by a left ventricular mass index, calculated by dividing left ventricular mass by height in meters to the power of 2.
In Uhl's anomaly, there is virtually complete absence of the myocardium of the parietal wall of the right ventricle and the parietal wall is composed of the opposing endocardial and epicardial ventricular surfaces, with no fatty tissue interposed between these layers.
We also agree that there are numerous characteristics of ventricular tachycardia easily applied to a resting 12-lead ECG (eg, QRS axis).
They focus on trabeculae at the left ventricular apex on the parasternal short axis and apical views and on the corresponding left ventricular wall thickness.
V fib--abbreviation for ventricular fibrillation; ventricles quiver instead of contract

Evans and White (12) (Figure 1) studied 33 patients at necropsy with considerable left ventricular hypertrophy (heart weight >750 g) and then reviewed their medical records to determine whether signs and symptoms of right-sided heart failure were isolated or simply preceded signs of left-sided heart failure (dyspnea).
