Evaluación ecocardiográfica de la sincronía ventricular: implicaciones en la selección de pacientes y en los resultados del tratamiento / Echocardiographic assessment of ventriculara synchrony: implications to patient selection and treatment outcome

ABSTRACT

Heart failure is one of the most prevalent diseases in industrialized countries. Up to 30% of the patients with advanced heart failure present disturbances in intra-ventricular conduction, and this produce asynchrony of ventricular contractility, leading to further deterioration in heart function. Cardiac resynchronization (TRC) is an increasingly important therapeutic option for a subgroup of patients with heart failure. Several methods have been show to be useful in study the mechanical asynchrony. However, there are discrepancies between the results of the different methods. The echocardiography provides the best parameters in predicting a good response.
