Assesment with three dimensional TEE
In order to obtain values of mitral valve parameters before CRT
implantation, real time 3 dimensional transesophageal echocardiography
(TEE) Vivid 9 Ultrasound system was used. Using TEE probe in
mid-esophageal position at full volume and in real time zoom mode with
long axis view from left atrial perspective, images including mitral
valve, aorta and LAA (left atrial appendix) and equivalent to surgical
view were obtained. In order to increase temporal resolution multibeat
images (at least 4 beat) (Frame rate: 8-12 Hz) in the region of
interest, distance between sectors was decreased and gain was optimized
to evaluate valve anatomy clearly and prevent artifacts. (Figure1)

Data obtained in 3D zoom mode were recorded with EchoPac PC Software,
Version 6.3 (GE Vingmed US, Horten, Norway), performing semi automated
analysis. Detailed measurments of mitral valve was accessed with 4D MVQ
(Mitral Valve Quantification, GE Healthcare) program automatically and
data were anlysed in offline mode. (Figure 2)
