Valvular disease Flashcards
Causes of acute AR
Infective endocarditis
Type A aortic dissection
Causes of chronic AR
Congenital - bicuspid aortic valve
Rheumatic heart disease
Connective tissue - Marfan’s
Autoimmune - Ank Spond, RA
Symptoms of AR
LVF - SOB, orthopnoea, PND
Arrhythmias
Angina
Signs of AR
Collapsing pulse Wide pulse pressure Apex displaced HS: Soft S2 +/- S3 Early Diastolic Murmur
Ix for AR
Bloods
ECG
CXR - pulmonary oedema, cardiomegaly
Echo
Mx of AR
