Aortic Valve Regurgitation

A comprehensive set of flashcards focused on Aortic Valve Regurgitation, covering definitions, causes, mechanisms, consequences, and clinical signs.

What is Aortic Regurgitation (AR)?

Abnormal reflux of blood from the aorta to the left ventricle in diastole due to incomplete valve closure.

What are the causes of Chronic Aortic Regurgitation (AR)?

Rheumatic AR, Infective Endocarditis, Dystrophic AR, Congenital Aortic Regurgitation.

What is a significant feature of Rheumatic AR?

Valve abnormalities including thickening, commissural fusion, and poor diastolic coaptation.

What is the impact of Infective Endocarditis on the valve?

It can lead to localized thickening of the valve and structural damage such as sigmoid tear and valve dysfunction.

What is Dystrophic AR associated with?

Aortic Root Lesion and Aortic Valve Lesion.

What congenital condition results in Bicuspid Aortic Valve (BAV)?

Having two unequal sigmoids instead of three.

What are the types of mechanisms that cause Aortic Regurgitation?

Type I: Normal Mobility, Type II: Increased Mobility, Type III: Reduced Mobility.

What compensatory mechanism occurs in Aortic Regurgitation?

Left ventricular volume overload leading to chronic LV dilation and hypertrophy.

What are the haemodynamic consequences of Aortic Regurgitation?

Maintained cardiac output, increased systolic pressure, decreased diastolic pressure, widened pulse pressure.

What clinical signs can indicate Aortic Regurgitation?

Diastolic murmur, systolic murmur, arterial hyperpulsatility (like Corrigan’s pulse).

What can chronic Aortic Regurgitation lead to over time?

Progressive LV dilation and eventual decompensation.

What is Aortic Regurgitation (AR)?

What are the causes of Chronic Aortic Regurgitation (AR)?

Rheumatic AR, Infective Endocarditis, Dystrophic AR, Congenital Aortic Regurgitation.

What is the impact of Infective Endocarditis on the valve?

It can lead to localized thickening of the valve and structural damage such as sigmoid tear and valve dysfunction.

What is Dystrophic AR associated with?

Aortic Root Lesion and Aortic Valve Lesion
