Clinical Trial Summary

We initiate this study to assess the diagnostic efficiency of PReTEE, a simplified TEE scan sequence with a combination of 3 valuable views of ME 4C, ME AV LAX and TG SAX, in identifying cardiac pathologies in the phase of difficult cardiopulmonary bypass separation among patients who will undergo high-risk cardiac surgical procedures.


Clinical Trial Description

There are 6 TEE operators who will participate in our trial, which is of restriction. Also, the participants we scheme to include are all junior TEE operators at our institute, who have already skilled at images obtainment and interpretation. Prior to the trial initiation, all these TEE operators will be randomly assigned into either the PReTEE group or the conventional TEE group with a 1:1 ratio (3 per group). Due to another limitation of eligible patients, TEE examinations thereby for patients are not conducted by equal numbers of operators stratified by groups. Furthermore, patients will be examined by 1-4 operators and 1 expert without removing the probe when separated from cardiopulmonary bypass. The ultimate sample size we calculate is 46 TEE examinations. ;
