[Update on cardiac imaging techniques: echocardiography, cardiac magnetic resonance and computed tomography].

This article contains a review of the most important contributions made by echocardiography, magnetic resonance imaging and computed tomography to the field of cardiology in 2009. During this period, we helped establish values for myocardial deformation parameters in a number of different clinical settings that have enabled us to achieve better understanding of systolic and diastolic function in both ventricles. Real-time three-dimensional echocardiography has provided new ways to improve the selection and monitoring of potential candidates for an increasing number of noncoronary interventions, such as percutaneous aortic valve implantation and percutaneous mitral valve repair. Magnetic resonance imaging has clearly become the technique of choice for studying a range of different conditions, such as myocarditis and various forms of cardiomyopathy, and is now established as the reference standard in clinical practice for determining the sizes of infarcts and myocardial areas at risk. The diagnostic potential of computed tomography for assessing heart disease has been confirmed in large multicenter trials.
