The mitral valve consists of a large anterior leaflet and a smaller posterior leaflet. It allows the passage of blood from the left atrium to the left ventricle, and prevents ‘backwards’ flow during ventricular contraction, so that blood is only permitted to flow into the aorta.
Mitral regurgitation is where blood travels ‘backwards’ from the left ventricle to the left atrium during ventricular contraction – this reduces the amount of blood pumped into the aorta.
As this condition worsens, the left atrium becomes larger to accommodate the ‘extra’ blood and this in turn places increased strain on the vessels in the lung (causing breathlessness).
If severe and untreated, this can lead to heart failure.
Exertional breathlessness is the most common symptom
Later in the course of disease patients may develop arrhythmias (atrial fibrillation) which significantly increase the risk of stroke
