Aortic valve prolapse (AVP) and aortic regurgitation (AR) are often associated with the ventricular outflow tract deficient form of ventricular septal defect (outlet VSD). We compared the accuracy of transesophageal echocardiography (TEE), transthoracic echocardiography (TTE) and cardioangiography at detecting AVP and AR in children with outlet VSD.
We recruited thirteen children with outlet VSD which complicated AVP. The location of VSD was based on Soto's classification, and final evaluation was based on the intraoperative findings.
5 cases were doubly committed subarterial, 6 cases were perimembranous and 2 cases were muscular outlet type. Regarding the location of VSD, surgical findings and preoperative TEE were all matched. The detection rate of AVP was equivalent with TEE and cardioangiography, while the rate was lower with TTE. The detection rate of AR with TEE was superior to both cardioangiography and TTE.
TEE provides accurate preoperative information in children with outlet type VSD in detecting AVP and AR.
