Answer 1

QUESTION : Which is the most common valvular dysfunction and how does it affect blood flow?

ANSWER:

• Valvular dysfunction is defined as the type of abnormality which is caracterized by defect in one of the four heart valves such as aortic, tricuspid, mitral, pulmonary.
• The most common valvular dysfunction is Mitral Valve Prolapse(MVP).

How does it affect blood flow?

• The main function of the mitral valve in the heart is to control the blood flow between the lower and upper chambers of the left side of the heart.
• When the heart pumps, the mitral valve closes completely and it also prevent the backward flow of blood from the upper left chamber which is also known as left atrium.
• When mitral valve does not function properly then the mitral valve dysfunction is occurs that means it allowing the blood to flow backward into the left atrium.
• Mitral valve backflow allow the blood to flow from the left ventricle back into the left atrium by which the heart does not pump sufficient amount of blood out of the left ventricle chamber.it causes the shortness of breath.
• The backflow of the blood can injury the muscles of the ventricle as well as the muscles of atrium.This muscles injury can lead to arrhythmias over time.
