Does right atrial hypertrophy require surgery?

Whether surgery is needed for right atrial enlargement depends on the underlying cause and severity of the condition—it may or may not be necessary. Details are as follows:

1. Surgery may be required

Right atrial enlargement refers to an abnormal increase in the size and structure of the right atrium, usually caused by cardiovascular diseases. First, if the enlargement is due to heart valve disease, surgical repair or valve replacement may be required. For example, severe mitral regurgitation leading to right atrial enlargement may necessitate mitral valve replacement to restore cardiac function. Second, if right atrial enlargement is caused by pulmonary hypertension, surgical intervention might be needed. For instance, pulmonary artery stenosis causing right atrial enlargement may require pulmonary artery dilation or pulmonary valve replacement surgery.

2. Surgery may not be required

If left atrial and left ventricular functions are normal, right atrial enlargement may not require surgical treatment, but close monitoring and management of the underlying cause are essential.

It should be noted that when considering surgical treatment, factors such as the patient's overall health, surgical risks, and prognosis must be comprehensively evaluated. If any discomfort occurs after surgery, prompt medical attention is recommended.
