Abstract:
Objective To discuss the application value of transesophageal echocardiography (TEE) in occluding procedure with cardiopulmonary bypass (CPB) for children muscular ventricular septal defects (mVSD).Methods Forty-nine mVSD patients for occluding procedure with CPB were performed guided and monitored by TEE,9 cases were simple mVSD,40 were mVSD combined with other cardiac malformations.The location,size,number,scope and the surrounding anatomy of mVSD were carefully observed before going into cardiac arrest,preparing the operator to choose appropriate occluder devices.The procedure was evaluated after the recovery of heart beat using TEE.Results In all of the 49 patients underwent occluding procedure,44 cases were implanted into one occluder,5 implanted into two occluders.The results of TEE after operation showed that the positions of all occluders were not shifted,2 had trace residual shunt,there were no complications worsening,such as mitral and aortic regurgitation,etc.One patient abandoned treatment for serious infection,the other patients' occluders were all in normal position followed up at 6 months to 2 years after operation,there were no tiny residual shunt and valves regurgitation except 1 patient.Conclusions The technique that TEE guiding and monitoring in occluding procedure with cardiopulmonary bypass for children muscular ventricular septal defects can shorten the time of cardiopulmonary bypass,significantly reducing complications and risks of the surgery,improving the successful rate.
