The main modalities
of investigations in AR are ECG, chest X-ray, echocardiogram and cardiac
catheterisation.
ECG findings in AR
1. ECG
– will show evidence of left ventricular hypertrophy (LVH)
2. There
will be diastolic overload pattern – that is prominent and tall T wave in
lateral leads
3. Increased
chance of intraventricular conduction disturbance.
Chest X-ray in aortic regurgitation
1. CXR
reveal cardiomegaly
2. Dilated
– aorta
3. Calcification
of aortic valve or root.
Echocardiography in aortic regurgitation
1. There
is dilated left ventricle
2. Regurgitant
aortic valve can be seen.
3. There
is fluttering of anterior mitral leaflet.
Indication of cardiac catheterisation on AR
It is routinely done in all patients
with aortic regurgitation.
