HOW ACCURATE ARE 3D-ECHO MEASUREMENTS? COMPARISON OF IN-VIVO MEASUREMENT OF PROSTHETIC VALVE SEWING RING DIAMETER TO KNOWN PROSTHESIS SIZE

We evaluated the accuracy of real-time 3D-TEE (RT3DTEE) by measuring mitral (MV) and aortic (AV) prosthetic sewing ring diameter and comparing to known prosthesis size. We also compared RT3DTEE accuracy to standard 2DTEE. RT3DTEE and 2DTEE were performed simultaneously in 30 consecutive patients
