Abstract：Objective To discuss the value of transesophageal echocardiography ( TEE ) in the minimally invasive mitral valve operation .Methods Totally 150 patients were performed minimally invasive mitral operation , 57 males and 93 female, mean age was (50.6 ±13.5) y.Severe mitral regurgitation were found in 116 patients, severe mitral stenosis were found in 18 patients, severe mitral regurgitation combined stenosis were found in 14 cases, 2 cases had mechanical prosthetic paravalvular leakage .Referring to Carpentier method to determine the lesion location , TEE was performed for venous cannula-tion guidance and building the extracorporeal circulation .Completing the mitral valvular operations by the right anterolateral minithoractomy through the 4th intercostals.Assess the effective deairing , cardiac function and the results of operation by the TEE at the time of weaning from cardiopulmonary bypass (CBP).Results Mitral valve repair (MVP) in 49, mitral valve re-place (MVR) in 98, MVR associated CABG in 1 case, repairing the perivalvular leakage in 2 cases (beating heart).In MVP 49 cases, mitral regurgitation area, vena contracta width, orifice area and maximum pressure grade across mitral orifice were (11.19 ±5.31)cm2 vs.(1.21 ±0.31)cm2( t =18.213, P <0.05), (7.48 ±2.75) mm vs.(1.07 ±0.51)mm ( t =7.320,P <0.05), (4.67 ±1.49) cm2 vs.(3.58 ±1.13)cm2( t =1.104,P >0.05), (3.07 ±1.11)mm Hg vs.(3.81 ± 1.44)mm Hg ( t =0.748, P >0.05) preoperative and postoperative respectively .Two cases of MVP were changed to MVR , because of unsatisfied efficacy evaluated by TEE .62 cases of MVR had no paravalvular leakage .Conclusion TEE is useful in guiding placement of the building of CPB , evaluating valve structure and the cardiac function and deairing detection during minimal invasive mitral valve operation .
