What are the causes of acute mitral regurgitation
- Infective endocarditis
- Acute rheumatic fever
- Mitral valve prolapse
- Marfan syndrome
- Myocardial ischemia
- Trauma
- Idiopathic
- Prosthetic valve dysfunction
Acute pulmonary oedema
Hypotension
What are the clinical signs of acute MR ?
Acute mitral regurgitation produces a set of clinical sign different from chronic mitral regurgitation
- Tachycardia
- Hypotension
- A wave / v wave in JVP
- Absence of cardiomegaly
- Forcible apex
- Palpable P2
- Thrill present
- Left parasternal heave present
- Loud P2
- LV S3, S4
- Loud descrendo murmur at the apex
So the striking differences are in blood pressure, absence of cardiomegaly, pulmonary artery, hypertension(PAH), left ventricular S4 (LVS4) and decrescendo murmur
