Selection Of Patients

Development and expansion of percutaneous interventional procedures in the catheterization laboratories during the last years have raised the need of imaging techniques capable to identify cardiac structures, guide the procedure, and exclude possible complications. Among different imaging techniques, echocardiography offers the advantage of its mobility and capability to assess different cardiac structures in real time. It has become the preferred method for a wide variety of cardiac procedures before, during, and after these interventions. Electrophysiology has also experienced a major change, as anatomy has proven to play a key role in arrhythmogenesis. This has forced a shift from an electrophysiologically guided procedure to an anatomically guided procedure, where imaging guiding has become essential to ensure an accurate knowledge of intra-cardiac anatomy and complement cardiac electrograms. Echocardiography plays an important function in three aspects for interventional cardiology: prior to the procedure, it provides information for the selection of patients; during the procedure, it can monitor and guide the intervention; and afterwards, it assesses the results. In the last years, 3D-transoesophageal echocardiography (3D-TEE) and intra-cardiac echocardiography (ICE) have proved their utility and safety, providing information regarding anatomy and physiology in real time. There is no question that the use of imaging techniques can enhance the results and safety of these procedures. The particular features of each intervention and the variety of techniques currently available force cardiologists from the fields of echocardiography, interventional cardiology, and electrophysiology to know the strengths and weaknesses of each imaging modality in order to reach their best performance.
