What happens if your right atrium is enlarged?

Enlargement of the right atrium can indicate underlying heart conditions, such as atrial fibrillation, pulmonary hypertension, or congenital heart defects. This enlargement may lead to increased pressure in the heart and lungs, causing symptoms like shortness of breath, fatigue, or palpitations. Over time, it can also increase the risk of blood clots, which can lead to stroke or other cardiovascular complications. Monitoring and treatment by a healthcare professional are essential to manage the condition effectively.
