Why the study?
Do preoperative TTE and intraoperative TEE measurements of the LVOT accurately predict the appropriate homograft aortic valve size in patients undergoing aortic valve replacement?
Population
26 consecutive patients undergoing aortic valve replacement with a cryopreserved human homograft

TEE and TTE LVOT measurements may aid homograft sizing; hypothesis-generating and needs prospective outcome validation.
Do preoperative TTE and intraoperative TEE measurements of the LVOT accurately predict the appropriate homograft aortic valve size in patients undergoing aortic valve replacement?
Measurement of the LVOT diameter by intraoperative TEE and preoperative TTE is reliable and clinically useful for selecting the proper size of homograft aortic valves.
FAN et al. (1997) studied this question.
