[Prevalence and evolution of left ventricular insufficiency in patients undergoing severe aortic insufficiency].

Introduction: Aortic insufficiency (AR) evolves during follow-up with dilation of the left chambers and eventually with deterioration of the ejection fraction (EF). Treatment as well as evolution of EF after the procedure remains uncertain. The objective of the following work was to establish the prevalence of ventricular dysfunction and evaluate the evolution of EF at 6 months in patients with aortic valve replacement (AVR) due to AR.

Surgical aortic valve replacement in patients with reduced ejection fraction. Prevalence and follow-up.

Introduction: Limited information exists on the prevalence and outcomes of patients undergoing surgical aortic valve replacement (SAVR) for aortic stenosis (AS) with reduced left ventricular ejection fraction (LVEF). This study aims to describe the number of AS patients undergoing SAVR with LVEF less than 55 % and quantify LVEF improvement at follow-up.

Material And Methods: We analyzed patients undergoing SAVR with LVEF less than 55 % and the number of patients that improved the LVEF at 6 months.
