Ventricular dyssynchrony From Wikipedia, the free encyclopedia. In cardiology, Ventricular dyssynchrony is a difference in the timing, or lack of synchrony, of contractions in different ventricles in the heart. Large differences in timing of contractions can reduce cardiac efficiency and is correlated with heart failure.

ventricular 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.

- Dilated cardiomyopathy (DCM) is a condition in which the heart 's ability to pump blood is decreased because the heart's main pumping chamber, the left ventricle, is enlarged and weakened. In some cases, it prevents the heart from relaxing and filling with blood as it should.

Ventricular Septal Defect: Closure in the Heart Catheterization Lab A ventricular septal defect is a hole between the two lower chambers of the heart. To close the hole, the doctor will place a special device in your child's heart. If the hole is too big to close with the device or in the wrong position, the hole will be closed with surgery.

What is DCD? The Dyspraxia Foundation is delighted to have been involved in the recent meetings to discuss and agree a UK description of Developmental Coordination Disorder (DCD): What is DCD? Developmental Co-ordination Disorder (DCD), also known as dyspraxia in the UK, is a common disorder affecting fine or gross motor co-ordination in children and adults. This lifelong condition is formally recognised by international organisations including the World Health Organisation.

Ventricular Septal Defect Ventricular septal defect is a hole in the wall between the right and left ventricles of the heart. This abnormality usually develops before birth and is found most often in infants. 1  The ventricles are the 2 lower chambers of the heart.2  The wall between them is called the septum. The ventricles are the 2 lower chambers of the heart. 2  The wall between them is called the septum. 3  A hole in the septum is called a septal defect. 4  If the hole is located between the upper chambers or atria, it is called an atrial septal defect.

- Pathophysiology. The natural history of supracristal ventricular septal defects (VSDs) depends on the location and size of the defect. Patients with small, isolated supracristal VSDs may have no symptoms or signs of congestive failure such as might be observed with a large shunt.

Septo-Optic Dysplasia Septo-optic dysplasia (SOD) is a rare disorder characterized by abnormal development of the optic disk, pituitary deficiencies, and often agenesis (absence) of the septum pellucidum (the part of the brain that separates the anterior horns or the lateral ventricles of the brain).

Ventricular Contractility Assessment (dP/dt)) Ventricular Contractility Assessment (dP/dt)) The rate (dP/dt max) of left ventricle (LV) pressure rise in early systole is one of the oldest measures of LV global contractility. The greater the contractile force exerted, the greater the rate of increase in left ventricular pressure. This rate can be measured invasively, using high-fidelity micromanometer catheters inside the LV, as well as non-invasively, from a continuous wave Doppler examination of mitral regurgitation jet.

- Background. A ventricular septal defect (VSD) is the most common form of congenital heart disease and is one of the most common cardiovascular anomalies in individuals with chromosome 22q11 deletion syndrome.

Congenital Heart Defects ASD (Atrial Septal Defect) Closure Definition Atrial septal defect is an abnormality of the upper chambers of the heart (atria) where the wall between the right and left atria does not close completely. This defect is present at birth (congenital). Causes, incidence, and risk factors. Atrial septal defect (ASD) is a congenital heart defect. In fetal circulation there is normally an opening between the two atria (the upper chambers of the heart) to allow blood to bypass the lungs. This opening usually closes about the time the baby is born.

Arrhythmogenic Right Ventricular Dysplasia Arrhythmogenic right ventricular dysplasia is a rare type of cardiomyopathy that occurs when the muscle tissue in the right ventricle is replaced with fatty or fibrous tissue. This can lead to disruptions in the heart’s electrical signals and causes arrhythmias.

dyskinesia an impairment of the ability to execute voluntary movements. Tardive dyskinesia is caused by an adverse effect of prolonged use of phenothiazine medications in elderly patients or persons with brain injuries.See also tardive dyskinesia.dyskinetic [-et′ik] , adj.rimary ciliary dyskinesia any of a group of hereditary syndromes characterized by delayed or absent mucociliary clearance from the airways; often there is also lack of motion of sperm. One variety is Kartagener's syndrome.

Wolff-Parkinson-White syndrome Definition. Wolff-Parkinson-White syndrome is an abnormality in the electrical functioning of the heart which may cause rapid heart rates. The abnormality affects the electrical signal between the atria and ventricles.

Ventricular septal defect A ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The ventricular septum consists of an inferior muscular and superior membranous portion and is extensively innervated with conducting cardiomyocytes. ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart.

- Left ventricular hypertrophy is a thickening of the wall of the heart's main pumping chamber. This thickening may result in elevation of pressure within the heart and sometimes poor pumping action. The most common cause is high blood pressure.

- A ventricular septal defect (VSD) is a hole between the two pumping chambers of the heart. The result of such a hole is that some of the blood returning from the lungs, which should be pumped to the body, is instead pumped back to the lungs.

Ventricular Aneurysm Imaging An aneurysm is a section of defective wall that bulges outward. A ventricular aneurysm is a defect in the left (or right) ventricle of the heart, usually produced by transmural infarction. (See the images below.) Left ventricular (LV) cineangiogram obtained during diastole depicts a large true aneurysm involving the anterior and apical walls of the LV in an elderly man.
