- Double outlet right ventricle. Double outlet right ventricle (DORV) is a heart disease that is present from birth (congenital). The aorta connects to the right ventricle (the chamber of the heart that pumps blood to the lungs), instead of to the left ventricle (the chamber that normally pumps blood to the body).

- The normal cardiac cycle, showing pressure relationships between the left-sided heart chambers. During diastole, the mitral valve (MV) is open, so that the left atrial (LA) and left ventricular (LV) pressures are equal. In late diastole, LA contraction causes a small rise in pressure in both the LA and LV (the a wave).

Right atrium Right atrium. The right atrium is one of the four chambers of the heart. The heart is comprised of two atria and two ventricles. Blood enters the heart through the two atria and exits through the two ventricles.Deoxygenated blood enters the right atrium through the inferior and superior vena cava.The right side of the heart then pumps this deoxygenated blood into the pulmonary veins around the lungs.ight atrium. The right atrium is one of the four chambers of the heart. The heart is comprised of two atria and two ventricles. Blood enters the heart through the two atria and exits through the two ventricles.

- The left atrium is one of the four hollow chambers of the heart. It plays the vital role of receiving blood from the lungs via the pulmonary veins and pumping it to the left ventricle. The left atrium is a small, hollow structure on the superior left side of the heart. It is separated from the right atrium by the interatrial septum and from the left ventricle by the bicuspid (mitral) valve.

Left Ventricular Hypertrophy What is Left Ventricular Hypertrophy? Left ventricular hypertrophy is a disorder of the heart involving the enlargement or thickening of the wall of cardiac muscle situated in the chamber of the heart known as the left ventricle.

Right ventricular hypertrophy Right ventricular hypertrophy is a form of ventricular hypertrophy affecting the right ventricle. Blood travels through the right ventricle to the lungs via the pulmonary arteries. If conditions occur which decrease pulmonary circulation, meaning blood does not flow well from the heart to the lungs, extra stress can be placed on the right ventricle. This can lead to right ventricular hypertrophy. It can affect electrocardiography findings. An ECG with right ventricular hypertrophy may or may not

- Tricuspid insufficiency (TI) , a valvular heart disease also called tricuspid regurgitation (TR), refers to the failure of the heart's tricuspid valve to close properly during systole.As a result, with each heart beat some blood passes from the right ventricle to the right atrium, the opposite of the normal direction.Tricuspid regurgitation occurs in roughly less than 1% of people and is usually asymptomatic, but may also be a feature of pulmonary hypertension and right-sided heart failure.s a result, with each heart beat some blood passes from the right ventricle to the right atrium, the opposite of the normal direction.

Why is the heart referred to as a double pump? Best Answer: THe heart is made up of two pumps; one that contains oxygenated blood, and one that contains deoxygenated blood...they are divided by this thick wall called a septum...each half is made up of a ventricle and an atrium...that question was on my science quiz today!!! 1. Double Pump.

Right Atrium Deoxygenated blood entering the heart through veins from the tissues of the body first enters the heart through the right atrium before being pumped into the right ventricle. The right atrium is one of the two atria of the heart, which function as receiving chambers for blood entering the heart. It is located to the right of the left atrium and superior to the much larger and more muscular right ventricle.

Right Ventricular Function and Failure The Normal Right Ventricle. The right ventricle pumps the same stroke volume as the left ventricle but with ≈25% of the stroke work because of the low resistance of the pulmonary vasculature. Therefore, by virtue of the Laplace relationship, the right ventricle is more thin walled and compliant (Figure 1).

- 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.

- Although conjoined twins, especially thoracopagus type, are known to present several cardiac anomalies, a shared single four-chambered heart with triple-outlet left ventricle is a rare condition. Only 17 percent of the total world population of conjoined twin accounts for this category.

Which of these vessels receives blood during ventricular systole? Right ventricular systole is pumping blood into the PULMONARY ARTERIES just as left ventricular systole is pumping blood into the AORTA -- both at the same time.

- The valve between the right atrium and the right ventricle is called the tricuspid valve. This valve opens to allow blood to be pumped from the right atrium in to the right ventricle. Once the blood has passed through the valve closes so the blood cannot pass back.

Patent Ductus Arteriosus (PDA) Therefore, a large left-to-right shunt through a patent ductus arteriosus (PDA) results in left atrial and left ventricular enlargement. The pulmonary veins and the ascending aorta can also be dilated with a sufficiently large patent ductus arteriosus (PDA).

Mitral valve Diastole ends with atrial contraction, which ejects the final 20% of blood that is transferred from the left atrium to the left ventricle. This amount of blood is known as end-diastolic volume (EDV), and the mitral valve closes at the end of atrial contraction to prevent a reversal of blood flow.he closing of the mitral valve and the tricuspid valve constitutes the first heart sound (S1). It is not the valve closure itself which produces the sound but the sudden cessation of blood flow, when the mitral and tricuspid valves close. There are some valvular heart diseases that affect the mitral valve.

Why Is the Heart Considered a Double Pump? The heart's right ventricle pumps blood to the lungs, while the left ventricle pumps the oxygenated blood to the body cells. The left ventricle is the stronger of the two and performs the more demanding part of the double-pump work. Continue Reading.

What does left atrial enlargement mean? Lung or heart disease are probably the most common reasons, but problems with the mitral valve can also result in left atrial enlargement - either a stiff valve that does not open well, or a leaky valve through which blood can go backwards in the heart. Left atrial enlargement is a not uncommon condition in adults. It means the left atrium of the heart (which holds blood before it goes into the left ventricle) is enlarged. This can happen for a number of reasons. Lung or heart disease are probably the most common reasons, but problems with the mitral valve can also result in left atrial enlargement - either a stiff valve that does not open well, or a leaky valve through which blood can go backwards in the heart.

Cardiac shunt A left-to-right shunt is when blood from the left side of the heart goes to the right side of the heart. This can occur either through a hole in the ventricular or atrial septum that divides the left and the right heart or through a hole in the walls of the arteries leaving the heart, called great vessels. cardiac shunt is when blood follows a pattern that deviates from the systemic circulation, i.e., from the body to the right atrium, down to the right ventricle, to the lungs, from the lungs to the left atrium, down to the left ventricle and then out of the heart back to the systemic circulation.
