MR Diagnosis

MR is usually diagnosed based on the characteristic heart murmur heard through a stethoscope during a routine visit.

Diagnosis of Mitral Regurgitation

A heart murmur is a distinctive sound produced by blood leaking backward into the left atrium when the left ventricle contracts. The disorder is sometimes diagnosed when a doctor hears this murmur through a stethoscope during a routine physical examination.

Electrocardiography (ECG) and chest x-rays show that the left ventricle is enlarged. If MR is severe, the chest x-ray may also show fluid accumulation in the lungs. Echocardiography, which uses ultrasound waves to produce an image of the heart structures and blood flow, provides the most information. This procedure can show the size of the atrium and ventricle and the amount of blood leaking so that the severity of the regurgitation can be determined.
