Echocardiographic assessment of aortic regurgitation: a practical guideline from the British Society of Echocardiography

Table 16 Classical features of aortic regurgitation in the chronic and acute setting

Chronic AR	Acute AR
Increasing LV size (LVEDd, LVEDV, LVESd, LVESV)	LV size is not dilated
LV remodeling (shape becomes more spherical)	Hyperdynamic LV systolic function
Deteriorating LV systolic function and LVEF	Increased LVOT VTI / Vmax
Increased wall mass	Premature closure of the MV
Normal LVEDP	Diastolic MR
	High LVEDP
	Decreased transmitral deceleration time
	Premature termination of diastolic flow (AR duration may be brief)

LV left ventricular, LVEDd left ventricular end diastolic dimension, LVEDV left ventricular end diastolic volume, LVESd left ventricular end systolic dimension, LVESV left ventricular end systolic volume, LVEF left ventricular ejection fraction, LVEDP left ventricular end diastolic pressure, LVOT VTI left ventricular outflow tract velocity time integral, Vmax velocity maximum, MV mitral valve, MR mitral regurgitation, AR aortic regurgitation
