The common symptoms of left atrial dilation include shortness of breath, chest pain, swelling, dizziness, irregular heartbeats, and palpitations. In the more severe cases, the person may faint because the heart cannot handle the pressure from stress or increased metabolism.
The left atrium is dilated or enlarged in mitral regurgitation as described above or when there is narrowing of mitral valve or it may be associated with aortic valve narrowing or hypertension or dilated cardio-myopathies. In your case it seems to be mitral regurgitation which is causing this. There are no other commonly seen conditions in otherwise healthy patients which cause left atrium to dilate or enlarge.
Causes of. The causes of dilatation of the left atrium may be various diseases or combinations of pathological processes: Deficiency, stenosis ( constriction) and prolapse ( reverse ventricular suction from the ventricle) of the mitral valve. Elevated blood pressure ( arterial hypertension). Stenosis ( constriction) of the aorta.
The left atrium (LA) is a crucial component of the cardiac physiology that partakes in collecting blood into the heart and modulates left ventricular filling during systole and diastole, respectively.[1] Left atrial enlargement (LAE) is the hallmark of the structural remodeling process, which occurs in response to chronic pressure and volume overload.
The 2022 edition of ICD-10-CM I51. 7 became effective on October 1, 2021. This is the American ICD-10-CM version of I51.
Left atrium enlargement (LAE) is when the left side of the heart enlarges or swells. It is often present in people with high blood pressure and heart valve issues. Doctors will work to find the underlying cause as a way of treating symptoms.

Conclusions: Dilatation of both right and left atria is common in chronic atrial fibrillation, and is associated with impaired left ventricular function. A longer duration of atrial fibrillation predisposes to atrial dilatation, left ventricular dysfunction, and functional atrio-ventricular regurgitation.
Left atrial enlargement (LAE) or left atrial dilation refers to enlargement of the left atrium (LA) of the heart, and is a form of cardiomegaly.
When the aortic or mitral valves are leaking, the left ventricle adapts to the increased volume load by getting larger. This results in cardiomegaly. If the aortic valve is narrow, this results in an obstruction to the left ventricle which develops hypertrophy and cardiomegaly.
Left ventricular hypertrophy, or LVH, is a term for a heart's left pumping chamber that has thickened and may not be pumping efficiently. Sometimes problems such as aortic stenosis or high blood pressure overwork the heart muscle.
In ICD-10-CM, the code for left ventricular hypertrophy is I51.

Dilated cardiomyopathy is a type of heart muscle disease that causes the heart chambers (ventricles) to thin and stretch, growing larger. It typically starts in the heart's main pumping chamber (left ventricle). Dilated cardiomyopathy makes it harder for the heart to pump blood to the rest of the body.

Once left atrial enlargement has occurred, treatment revolves around addressing the factors that caused it. High blood pressure can be treated in the following ways: taking medications, such as beta-blockers, calcium channel blockers, alpha-beta-blockers, and diuretics. eating a heart-healthy diet.
Cumulative 10-year survival was 73.7% among patients with normal left atrial size, 62.5% among those with mild enlargement, 54.8% among those with moderate enlargement and 45% among those with severe enlargement (p < 0.001).
Many different causes can lead to DCM, such as: Infections, such as HIV and Lyme disease. Autoimmune disease, such as polymyositis. Alcohol abuse, cocaine use, exposure to heavy metals, and certain chemotherapy drugs.
“I advise not to be too concerned about the left atrial enlargement seen with high-intensity exercise and its potential effect on the risk of future atrial fibrillation,” Dr. Kanj continues.
