[Biventricular resynchronization in the management of the chronic heart failure]

Heart failure is a major problem of public health, it represents a frequent status among patients with heart disease, and its implications in term of mortality and cost are high. Non Pharmacological treatment of heart failure most commonly designed as cardiac resynchronization therapy [CRT] has demonstrate efficacy to improve functional class, exertion capacity, left ventricular ejection fraction, reduction of mitral regurgitation, and probably mortality at midterm. The most recent studies emphasize on the role of implantable cardioverter defibrillat or [ICD] combined with CRT to reduce mortality. More trials are needed to valid this concept
