ObjectiveTo investigate the application value of intraoperative transesophageal echocardiography（TEE）in cardiac surgery in basic hospital.MethodsNinety-five cardiac surgery patients were monitored by intraoperative TEE.Their cardiac and macrovascular structures

functions and blood flow were completely examined and evaluated during cardiopulmonary bypass

or before/after cardiac surgery

to guide the revision of operation plan

evaluate the effect of operation and guide whether to operate again.ResultsDiagnosis was corrected for 26 patients（27.4%）before cardiopulmonary bypass or cardiac surgery by TEE

of which 7 cases did not affect the operative procedures and 19 cases affected the surgical planningoperation scheme.Fortytwo patients（44.2%）received decisional intervention

including 30 cases of valvular disease and 12 cases of non valvular disease.All patients received general intervention.ConclusionIntraoperative TEE can be used for preoperative modification of diagnosis

intraoperative continuous monitoring and guiding

and immediate postoperative evaluation of operative effect

which has important clinical application value.
