Abstract

CARVAJAL-RIVERA, José Julián et al. Fusion of 2 D and 3 D echocardiography with fluoroscopy: a new tool in cardiac interventionism. Rev. Colomb. Cardiol. [online]. 2018, vol.25, n.1, pp.55-66. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2017.05.015.

The evolution of percutaneous structural interventionism has led to the simultaneous development of advanced imaging techniques. Taking into account that these types of procedures require a full understanding of cardiac anatomy, and with the aim of ensuring the best results and patient safety during complex procedures, a software program was developed that was capable of fusing and 3D-echocardiography into a single image. The Echonavigator® technology combines two dynamic imaging techniques of a heart in movement. The appropriate co-recording and visualising of fluoroscopy and 2D/3D transoesophageal echocardiography is essential for obtaining optimal results. The fusion of two images in real-time is a feasible and safe tool in structural heart interventionist procedures. Initial studies have managed to decrease the time of performing the procedures, as well as the dose of radiation to the patient. The future is promising, and its gradual expansion of use, taking into account its recent appearance, will provide more data on the growth of this technology.
