Heart Failure (Definition)

Heart failure is a complex set of conditions in which the heart "fails" to pump a normal amount of blood with each beat. This can be due to poor squeezing function (systolic heart failure) and/or a stiff heart incapable of filling normally (diastolic heart failure). Common symptoms include swelling and trouble breathing, particularly when ...Read more

What is pathophysiologic of right sided heart failure !?

What is pathophysiologic of right sided heart failure !?

Right heart failure: The commonest cause of right heart failure is left heart failure. The causes of isolated right heart failure include primary pulmonary hypertension and pulmonary diseases associated with pulmonary hypertension. Left to right cardiac shunts cause right heart failure and mitral stenosis is another(techinically this is a left heart cause. ...Read more

Does cor pulmonale = right sided heart failure?

Does cor pulmonale = right sided heart failure?

Sort of: Cor pulmonale is the inability of the right side of the heart to pump blood through the lungs. One common cause is left-sided heart failure and this isn't cor pulmonale. A host of lung diseases cause cor pulmonale and some folks use the term to include heart failure due to pulmonary thromboembolization. ...Read more

Physical exam: Fluid accumulates during congestive heart failure. When the right side of the heart fails, fluid accumulates in the legs and abdomen. When the left side of the heart fails, fluid accumulates in the lungs and makes the patient short of breath. Not infrequently, both sides of the heart fail at the same time. ...Read more

What cuases hypoplastic left heart syndrome?

Multifactorial.: 2-6% recurrence risk with 1-2 prior affected siblings and up to 25% risk with rare familial autosomal recessive forms - both point to genetic underpinnings. The pathological changes center around severe aortic and mitral valve stenoses and hypoplasia/interruption of the aortic arch. ...Read more

What is right side heart failure vs. Left sided?

What is right side heart failure vs. Left sided?

Right heart failure: Right heart failure refers to weakness or stiffness involving the right ventricle or lower chamber as opposed to the left ventricle. This causes a unique constellation of symptoms including swelling in abdomen and legs, liver malfunction, weakness and shortness of breath. ...Read more

What's the difference between congestive heart failure and right heart failure?

What's the difference between congestive heart failure and right heart failure?

Similar: Congestive heart failure refers to the congestion (fluid buildup) which is seen in the lungs and the legs (swelling) and in the abdomen. (might be swollen). Heart failure can involve both the right and left sides of the heart depending on the exact cause. The most common cause of right heart failure is left heart failure but certain things such as lung disease can cause just right heart failure. ...Read more

Small left sided heart with abnormal septal motion in ventricle EF 60-65% heart is normal including thickness. Possible pulmonary hypertension cause?

MRI: If you have severe pulmonary hypertension, you may have Primary Pulmonary Hypertension. This is potentially a serious diagnosis. Intracardiac and intrapulmonary shunting must be ruled out. A cardiac MRI and nuclear shunt test can make this determination. These tests are likely only available at a major referral center - London. Good luck. ...Read more

What's the difference between left heart failure vs right heart failure?

What's the difference between left heart failure vs right heart failure?

R/L heart failure: Right heart (right ventricle and atrium) failure typically has dependent edema, liver enlargement and increased jugular venous pulsations. Left heart (left ventricle and atrium) failure typically manifests with pulmonary edema. You can even have a combination of the two. This classification is not used as much. We have a systolic, a diastolic and mixed heart failure- this is the most used. ...Read more

How does left heart failure lead to right heart failure or chf?

How does left heart failure lead to right heart failure or chf?

Left heart failure: Left ventricle is the main pumping chamber of the heart and damage to that chamber either from a heart attack or a cardiomyopathy can lead to heart failure. Congestive heart failure is a condition where the heart cannot pump the blood delivered to it and backs up into the lungs causing shortness of breath. This can be caused by left heart failure, and can also lead to both chambers failing. ...Read more

How are the symptoms of right sided heart failure different from left heart?

How are the symptoms of right sided heart failure different from left heart?

Findings: One must remeber that the most common cause of right heart failure is left heart failure and thuswhat is often referred to as left heart failure can represent biventricular failure. Isolated left heart failure usually manifests in pulmonary edema and shortness of breath. Right heart failure can manifest as passive liver congestion, periphera edema, elevated venous jugluar pressures, etc. ...Read more

What is left-sided heart failure from?

What is  left-sided heart failure from?

Left ventricle: The left ventricle is dysfunctional either during systole (squeezing). Or diastole (relaxing) or both. In either case, forward flow of blood through the heart to the body is impaired. This leads to blood backing up into the lungs causing shortness of breath. ...Read more

Can someone describe the difference between left heart failure and right heart failure?

Can someone describe the difference between left heart failure and right heart failure?

Some together: Left heart muscle ischemic, dead or scarred and does not push blood well( low ejection fraction), low blood pressure, and may back up and strain right heart and get pulmonary fluid retention, edema, peripheral edema. If right side muscle dies, scars or is under back pressure from bad lungs, pulmonary embolism it may show first signs, but left heart is not happy either due to poor inflow. Simple? ...Read more
