An understanding of normal morphologic anatomy is basic to the accurate diagnosis of congenital heart disease. (thoracickey.com)
One of the diagnostic problems posed by complex congenital heart disease is that any cardiac chamber, valve, or vessel can be virtually "anywhere. (thoracickey.com)
Consequently, the diagnostic identification of the cardiac chambers cannot be based on relative position (such as right sided or left sided) nor on function (such as venous or arterial), because position and function are variables in congenital heart disease. (thoracickey.com)

What Causes Congenital Heart Disease? (adventhealth.com)
Echocardiography indicated that she had congenital heart disease of double-outlet right ventricle. (springeropen.com)
The incidence of pregnancy with cardiac disease ranges from 0.4 to 4.1 %, and congenital heart disease takes up a large proportion (McFaul et al. (springeropen.com)
1972 ). Signs of heart failure often appear when the patient is young, so this disease is often diagnosed and treated early (Lacour-Gayet 2008 ). (springeropen.com)

Or it may be caused by a form of heart muscle disease (cardiomyopathy). (ketteringhealth.org)

In dilated cardiomyopathy, the heart cavity becomes dilated (enlarged) and its ability to pump blood becomes significantly reduced. (singaporedoc.com)
Many patients with dilated cardiomyopathy go on to develop heart failure. (singaporedoc.com)

An associated Ebstein deformity of the tricuspid valve is found in 10% of the cases, further complicating the anatomy and the function of the right ventricle. (unipd.it)

The coronary arteries are on the heart surface (left main, right coronary). (medicinenet.com)
These arteries and their branches supply all parts of the heart muscle with blood. (medicinenet.com)
The heart has four main arteries: Left Coronary, Right Coronary, Aorta and Pulmonary. (hemopet.org)
Coronary and peripheral interventions refer to non-surgical procedures that use a catheter (a thin flexible tube) and small tools to remove plaque (a mixture of cholesterol, fat, calcium and other substances) and restore blood flow through the vessels in the heart and peripheral arteries.

The heart has four chambers. (stroke.org)
Blood is pumped through the chambers, aided by four heart valves. (stroke.org)
An ASD is a hole in the wall between the two upper chambers of the heart called the right and left atria. (nicklauschildrens.org)
The right and left sides of the heart are further divided into two top chambers called the atria (also termed the right and left atrium ), which receive blood and then pump it into the two bottom chambers called ventricles, which pump blood to the lungs and to the body. (medicinenet.com)
Normal heart anatomy and physiology need the atria and ventricles to work sequentially, contracting and relaxing to pump blood out of the heart and then to let the chambers refill. (medicinenet.com)
A heart valve is a one-way valve that allows blood to flow in one direction through the chambers of the heart . (wikipedia.org)
The heart valves and the chambers are lined with endocardium . (wikipedia.org)
The heart has four chambers: Left Atrium, Left Ventricle, Right Atrium and Right Ventricle. (hemopet.org)
Valves are located between each of the chambers. (hemopet.org)
We will start with the significant heart valve conditions in dogs by the route blood flows through the heart, and then discuss holes in the septums separating the heart chambers or in the valves. (hemopet.org)
Unless the chambers of the heart can adequately fill up with blood during the process of dilatation (when the heart relaxes), the heart cannot pump out sufficient volumes of blood. (singaporedoc.com)
Image 2 features a different heart with an atrioventricular septal defect that allowed systolic shunting between the left and right chambers at the ventricular level only. (ipccc.net)
A hole between 2 chambers of the heart is an example of a very common type of congenital heart defect. (ketteringhealth.org)
This lets blood flow between the right and left chambers of the heart. (ketteringhealth.org)
In this condition, there is an opening between the 2 upper chambers of the heart (the right and left atria). (ketteringhealth.org)

If severe symptoms of high blood pressure and heart failure develop, surgery is needed. (ketteringhealth.org)
