Abstract:
Objective To investigate the difference between three-dimensional transesophageal echocardiography ( 3DTEE) and CT in measuring the size of aortic ring and the height of coronary ostium . Methods Fifteen patients were recruited and were treated with the transcatheter aortic valve implantation ( TAVI) . Routine transthoracic echocardiography ,two-dimensional echocardiography ( 2DTEE) ,3DTEE and CT examinations were taken preoperatively . Results The minimal diameter ,maximum diameter , perimeter ,area of the aortic ring measured by 3DTTE showed a close correlation and a strong consistency with those measured by CT [ r = 0 .88 , P < 0 .0001 ,ICC = 0 .928 (0 .788 - 0 .976) ; r = 0 .81 , P = 0 .0003 , ICC = 0 .890 ( 0 .673 - 0 .963) , r = 0 .85 , P = 0 .0001 ,ICC = 0 .914 ( 0 .744 - 0 .971) ; r = 0 .88 , P <0 .0001 ,ICC = 0 .932 (0 .799 - 0 .977) ] .The ostium height of the left and right coronary arteries measured by 3DTEE also showed a close correlation and a strong consistency with those measured by MDCT [ r =0 .87 , P < 0 .0001 ,ICC = 0 .923 ( 0 .777 - 0 .975) ; r = 0 .82 , P < 0 .0002 ,ICC = 0 .897 ( 0 .693 - 0 .965) ] . Besides ,inter-observer and intra-observer reproducibility for 3DTEE measurement data were very good . Conclusions 3DTEE has a high repeatability in evaluating minimal diameter , maximum diameter , perimeter ,area of the aortic ring and the height of coronary ostium ,which also shows good correlation with those measured by CT .
