can mitral valve regurgitation cause atrial fibrillation?
122896
Mitral valve regurgitation can cause complications such as: Atrial fibrillation, in which the atria of the heart don't contract well. This leads to increased risk of stroke. Elevated blood pressure in the lungs (pulmonary artery hypertension)

"In atrial fibrillation, it may sound almost like when your shoes are in the dryer, going all over the place." Atrial fibrillation is a type of arrhythmia, which literally means "not rhythmic," hence the somewhat random "shoes in the dryer" effect, which you can also feel in your pulse.

This can cause a variety of symptoms, including decreased blood pressure, light-headedness, weakness and shortness of breath. Occasionally, the rapid heart rate associated with atrial fibrillation can result in chest pain or discomfort (angina) because of reduced blood flow to the heart muscle.

How can atrial fibrillation (AFib) cause cardiomyopathy? ANSWER. AFib makes the ventricles beat faster to push blood out of the heart. Beating too fast for a long time can make the heart muscle too weak to pump enough blood to your body. This is called cardiomyopathy.

A fibrillating atrium quivers and doesn't pump efficiently, which increases the risk for blood clots that may cause a stroke. Another potential complication of mitral regurgitation is pulmonary hypertension. Treatment for mild mitral regurgitation may include anticoagulation medication.

Diagnosis – Mitral Regurgitation Left atrial enlargement, indicated by broadening of the P wave, occurs due to the increased time required for propagation of electrical activity throughout the enlarged left atrium. Left ventricular hypertrophy may also be present.

A: It is not uncommon for atrial fibrillation (AFib) to occur at night. The nerves that control the heart rate typically are in sleep mode, and resting heart rate drops. Under these conditions, pacemaker activity from areas other than the normal pacemaker in the heart can trigger the onset of AFib.

Abstract. Atrial fibrillation (AF) is a significant cause of morbidity and health care expenditures. Patients with AF suffer a variety of symptoms including chest pain, palpitations, shortness of breath, and fatigue. Some patients have no symptoms, a condition referred to as asymptomatic or "silent" AF.

Should I be worried? A: It is not uncommon for atrial fibrillation (AFib) to occur at night. The nerves that control the heart rate typically are in sleep mode, and resting heart rate drops. Under these conditions, pacemaker activity from areas other than the normal pacemaker in the heart can trigger the onset of AFib.

You may have heard of two types of AFib: valvular and nonvalvular. Valvular AFib affects people who have mitral valve disease or an artificial valve. Nonvalvular AFib is caused by other things, such as high blood pressure or an overactive thyroid gland. Doctors don't always know what the cause is.

Widely disparate estimates of long term survival in patients with mitral regurgitation—between 97–27% at five years—have been reported. We analysed the natural history of mitral regurgitation caused by flail leaflets because these patients present with severe mitral regurgitation in more than 85% of cases.

Mitral valve prolapse and regurgitation Sometimes mitral valve prolapse causes blood to leak back into the atrium from the ventricle, which is called mitral valve regurgitation. Congenital mitral valve anomalies are defects present at birth (congenital) that affect the heart's mitral valve.

Left untreated, severe mitral valve regurgitation can cause heart failure or heart rhythm problems (arrhythmias). Even people without symptoms may need to be evaluated by a cardiologist and surgeon trained in mitral valve disease to determine whether early intervention may be beneficial.

Syncope. This case illustrates several points: atrial fibrillation rarely causes syncope and does not usually cause hypotension when ventricular rates are normal.

Stress can contribute to heart rhythm disorders (arrhythmias) such as atrial fibrillation. Some studies suggest that stress and mental health issues may cause your atrial fibrillation symptoms to worsen. High levels of stress may also be linked to other health problems.

Atrial fibrillation occurs in the heart's upper two chambers, also known as the atria. Ventricular fibrillation occurs in the heart's lower two chambers, known as the ventricles. If an irregular heartbeat (arrhythmia) occurs in the atria, the word “atrial” will precede the type of arrhythmia.

Mitral valve regurgitation symptoms When mitral regurgitation is severe, the blood backs up into the lungs. This leads to congestive heart failure, which causes fatigue, fluid retention and shortness of breath.
