Original Title: Ecocardiografía transesofágica en tiempo real 3D (ETE-TR-3D) frente a 2D.

Authors' objectives: The overall objective of this report is to assess the use, usefulness, security and effectiveness of the RT-3D-TEE in terms of: 1. Analytical validity: to evaluate the reliability the RT-3D-TEE in detection of cardiac alteration (anatomical level and/or functional). 2. Clinical validity: to evaluate the accuracy the RT-3D-TEE to predicts clinical outcome. The secondary objectives are to determine the cost of the test in terms of: 1. Device Costs: equipment, consumables and maintenance. 2. Associated Costs: consumption of time, staff necessary, medications and complications. 3. To estimate the budget impact of use of the test for the NHS.

Authors' results and conclusions: • The studies included in the systematic review have a high heterogeneity with regard to their methodological quality, as well as to the outcome measures used and evaluated test indications. The quality of the available evidence is generally moderate-low, given that there are few comparative studies with suitable gold standard and who have used correctly the blinded data. • We can deduce that RT-3D-TEE has proved more effective than 2D in several indications, providing evidence of moderate-high quality in the assessment of the mitral valve, to measure left atrial appendage orifice area and entry tear diameter measured in the aortic dissection. • RT-3D-TEE was more accurate than 2D-TEE in the evaluation of the aortic annulus diameter as predictor method of aortic insufficiency after implantation of percutaneous valve, although the measurements obtained with 3D-TEE are somewhat lower than those obtained with CT which could imply some underestimation of the size of the prosthesis. • The incidence of complications related with the RT-3D-TEE is very low and similar to 2D-TEE, because the technique is identical. • The unit cost of the test RT-3D-TEE for the SNHS was estimated between 45.15 and 79.69 Euros, excluding the costs of equipment maintenance and the probe. For 2D-TEE the estimated unit cost was in the range 41.13-57.35€. The differences or amplitudes of the estimates due to the acquisition cost sharing is based on the number of annual tests with the device and have assumed two scenarios, one of the best uses (which implies a lower cost) and other scenario with low-use of the device. • The estimation of the number of procedures of RT-3D-TEE for the years 2012 and 2013 is between 7,551 and 7,947 in the SNHS, making conservative estimations of test indications. The whole cost would be between 340,907-601,707€ for 2012 and between 358,785-633,262€ in 2013 for the whole of the NHS within RT-3D-TEE. Using 2D the amounts are between 373,786-496,307€ in 2012, and in the range of 393,388-522,336€ for 2013.
