Manual versus automatic detection of aortic annulus plane in a computed tomography scan for transcatheter aortic valve implantation screening
Key result
Automatic aortic annular plane detection using Syngo Aortic ValveGuide showed good agreement with manual measurement for effective aortic annulus diameter (mean difference 0.16 mm).
Why the study?
Does automatic detection of the aortic annulus plane using Syngo Aortic ValveGuide provide comparable effective diameter measurements to manual adjustment in patients undergoing TAVI screening?
Population
73 raw image datasets of preoperative TAVI MSCT scans

Cite This Study
Linden et al. (2014) conducted an observational in Transcatheter aortic valve implantation (TAVI) screening (n=73). Syngo Aortic ValveGuide (automatic annular plane detection) vs. 3Mensio Valves (manual annular plane adjustment) was evaluated on Effective aortic annulus diameter (MD 0.16, 95% CI -0.48 to 0.80). Automatic aortic annular plane detection using Syngo Aortic ValveGuide showed good agreement with manual measurement for effective aortic annulus diameter (mean difference 0.16 mm).
