Criteria for Prosthetic Aortic Valve Regurgitation

Prosthetic aortic valve regurgitation can be classified based on a number of objective parameters.

Patient selection: prosthetic aortic valve

Conditions: normal or near normal stroke volume (50-70 mL)

Parameters:

(1) valve structure and motion

(2) left ventricular size

(3) jet width of central jet on Doppler

(4) jet density on continuous wave Doppler

(5) jet deceleration ratee

(6) left ventricular outflow versus pulmonary flow on pulsed wave Doppler

(7) flow reversal in descending aorta on pulsed wave Doppler

(8) circumferential extent of paraprosthetic regurgitation

(9) regurgitant volume in mL per beat

(10) regurgitant fraction in percent

	dilated	severe
central jet width	narrow	mild
	intermediate	moderate
	large	severe
jet density	incomplete or faint	mild
	dense	moderate
	dense	severe
jet deceleration	slow	mild
	intermediate	moderate
	steep	severe
left ventricular outflow	slightly increased	mild
	moderately increased	moderate
	greatly increased	severe
flow reversal in descending aorta	absent or brief early diastolic	mild
	intermediate	moderate
	prominent, holodiastolic	severe
circumferential extent of paraprosthetic regurgitation	< 10%	mild
	10-20%	moderate
	>20%	severe
regurgitant volume	<30 mL per beat	mild
	30-59 mL per beat	moderate
	>=60 mL per beat	severe
regurgitant fraction	< 30%	mild
	30-50%	moderate
