Differential flow improvements after valve replacements in bicuspid aortic valve disease: a cardiovascular magnetic resonance assessment

Table 2 Ascending aortic flow pattern parameters by aortic valve replacement subgroup

	Healthy Subjects	BAV- native	AVR-mechanical	AVR-tissue	Ross
Total number (male)	30 (23)	30 (23)	11 (10)	10 (9)	9 (8)
Time after operation in months (range)			6 (3–14)	9 (1–37)	126 (1–268)
Indication for AVR:
Aortic stenosis			4	7	8
Aortic regurgitation			5	1	1
Both			2	2
Fusion pattern pre-AVR:
RL-BAV			7	5	Data
RN-BAV			2	5	unavailable
Others			2
Flow pattern post-AVR:
Normal flow	30	5 (17%)	8 (73%)	0	6 (67%)
Right-handed flow		21 (70%)	2 (18%)	8 (80%)	2 (22%)
Left-handed flow		1 (3%)	1 (9%)	1 (10%)	1 (11%)
Complex flow		3 (10%)	0	1 (10%)

Values are mean ± standard deviation except where indicated; BAV = bicuspid aortic valve; AVR = aortic valve replacement; RL-BAV = right-left coronary cusp fusion pattern bicuspid aortic valve, RN-BAV = right-non-coronary cusp fusion pattern bicuspid aortic valve
