- Abstract
Purpose: The coexistence of mitral regurgitation (MR) and severe aortic stenosis is a common problem in elderly patients that limits the indication for percutaneous aortic prosthesis (TAVI). However, recent publications indicate a decrease in MR after TAVI because of the improvement of left ventricle (LV) hemodynamic conditions. The aim of our study was to investigate clinical and echocardiographic predictors of MR after TAVI. Methods: We included patients undergoing TAVI from May 2008 to November 2012. It was performed a 3D transesophageal echocardiogram during the procedure and a transthoracic echocardiogram before discharge and 12 months after implantation. We studied the etiology of MR before procedure, LV ejection fraction, chambers volume, pulmonary hypertension and tricuspid regurgitation, as well as clinical and technical variables related to the procedure. Results: 90 patients underwent TAVI successfully (Table). At the beginning, 21% of patients had MR at least grade III/IV. After TAVI, 84.4% of patients showed no change in MR degree, 12.2% improved and only 3.3% worsened. Variables related with MR worsening were rheumatic MR etiology, history of atrial fibrillation (AF) and the coexistence of significant tricuspid regurgitation (TR) in the baseline study (p <0.04, p <0.01; p <0.03, respectively). Conclusions: In patients undergoing TAVI, the rheumatic etiology of MR, the previous history of AF and significant TR coexistence were factors related to MR worsening after the procedure.

- Abstract
Purpose: With the advent of percutaneous transcatheter device closures in congenital heart defects and the emergence of percutaneous left atrial appendage closure, there is an increasingly important role for echocardiographic guidance and control of device position and function. Disc occluder devices frequently present as an unexplained ‘figure-of-8’ on echocardiography. The aim of this study was to clarify this ‘figure-of-8’ display and to relate its morphology to transducer position and device type. Methods: A mathematical model was developed to resemble disc occluder geometry and to allow a numerical simulation of the echocardiographic appearance. In addition, we developed an in vitro set-up for echocardiographic analysis of various disc occluders and various transducer positions. Results: In the mathematical model of an epitrochoid curve (closely resembling disc occluder geometry) a ‘figure-of-8’ display is obtained when emphasizing points with tangent vector perpendicular to the direction of ultrasound waves. Decreasing imaging depth results in a more asymmetric ‘figure-of-8’, with small upper part and wide lower part. Clinical and in vitro data are in close agreement with these results (Figure 1). Furthermore a ‘figure-of-8’ display is only obtained in a coronal imaging position, and is similar for different commercially available disc occluder types. Conclusions: The ‘figure-of-8’ display in the ultrasound image of a disc occluder is an imaging artifact due to the specific ‘epitrochoidal’ geometry of a deployed device and its interaction with ultrasound waves. The morphology of the ‘figure-of-8’ depends on transducer position, i.e. imaging depth, and is similar for different device types.
