Aims: Mitral regurgitation (MR) is a complication that may occur during transcatheter aortic valve implantation (TAVI) in a certain percentage of cases and may require different treatments depending on the mechanism. Our purpose was to describe the occurrence rate of this complication during TAVI with the CoreValve prosthesis, as well as to assess the usefulness of transesophageal echocardiogram (TEE) in the detection of the mechanism of MR.
Methods And Results: We analyzed a total of 129 cases of severe aortic stenosis treated with CoreValve prosthesis from June 2008 to October 2011.
Usefulness of transesophageal echocardiography during implantation of the CoreValve percutaneous aortic prosthesis: influence of the learning curve.

Background And Objectives: The purpose of this study was to evaluate the usefulness of transesophageal echocardiography during the implantation of the CoreValve percutaneous aortic prosthesis and the influence of the learning curve in its indications.
Methods: From April 2008 to January 2010, 53 patients were treated for symptomatic severe aortic stenosis with a CoreValve percutaneous aortic prosthesis. Transesophageal echocardiography was performed during the procedure for two reasons: if a discrepancy between the measures of the aortic annulus arose before the implantation and to provide visualization if a complication occurred during the procedure.
Purpose: We aimed to analyze the feasibility of two-dimensional speckle-tracking echocardiography (2DSTE) in evaluating myocardial strain in consecutive, nonselected patients in daily clinical practice.
Methods: Strain analysis using 2DSTE was attempted in 59 consecutive patients: 24 patients with severe aortic stenosis, 28 patients with dilated cardiomyopathy, and 7 healthy controls. The analysis was done by four expert echocardiographers and one cardiology resident.
