The right side of the heart is responsible for pumping blood to the lungs to collect oxygen in a process called oxygenation, while the left side pumps blood to the rest of the body. Again, the increased pressure that this creates in the left atrium can cause it to enlarge. Diagnosing left atrial enlargement can help doctors determine the risk of a heart attack in people with high blood pressure. In mitral stenosis, the mitral valve is narrowed. This test uses high-frequency sound waves or ultrasound to produce pictures of the heart.
