The downward slope - Rheumatic fever - Mitral valve regurgitation
3 important questions on The downward slope - Rheumatic fever - Mitral valve regurgitation
What is mitral valve regurgitation?
Blood travels back through the mitral valve into the atrium during ventricular contraction.
What are the symptoms of mitral valve regurgitation?
Palpitations: increased stroke volume
Dyspnoea and orthopnea: pulmonary hypertension/ oedema
Fatigue and lethargy: decreased cardiac output
Right heart failure: enlarged right atrium- may eventually lead to congestive cardiac failure
Cardiac cachexia: unintentional severe weight loss as a result of cardiac disease
Thromboembolism
Subacute infective endocarditis

What are the signs of mitral valve regurgitation?
-laterally diffused apex beat
- systolic thrill- heart murmur that is palpable
- soft S1- damage to the valve and incomplete closing
-pansystolic murmur- back flow of blood into the atria throughout the whole of systole
- prominent S3 heard- due to rapid rush of blood into a dilated ventricle.
