Secondary mitral regurgitation (MR) is more frequent, portends a worse prognosis and its diagnostic and management are more difficult in comparison with primary MR. The mechanism of secondary MR is linked to the left ventricle remodeling, while the valve morphology is normal. Surgical treatment of severe secondary MR consists either in mitral valve replacement or in mitral valve repair. The mos...

Transcatheter aortic valve implantation, as well as interventional mitral valve repair, offer reasonable therapeutic options for high-risk surgical patients. We report a rare case of early post-interventional aortic valve prosthesis migration to the left ventricular outflow tract, with paravalvular leakage and causing severe mitral valve regurgitation. Initial successful interventional mitral v...

Echocardiography is an essential tool in managing patients with mitral regurgitation. It allows identification and precise summation of anatomic lesions that lead to valve dysfunction. In this article, we highlight important aspects of mitral valve anatomy and pathophysiology as they pertain to surgical repair and discuss the critical role of echocardiography in surgical planning and assessment...

PURPOSE In mitral valve prolapse, determining whether the valve is suitable for surgical repair depends on the location and mechanism of regurgitation. We assessed whether cardiovascular magnetic resonance (CMR) could accurately identify prolapsing or flail mitral valve leaflets and regurgitant jet direction in patients with known moderate or severe mitral regurgitation. METHODS CMR of the mi...

OUTFLOWTRACT OBSTRUCTION IS A FEAREDAND POTENTIALLY LETHAL COMPLICATION OF TRANSCATHETER mitral valve replacement (TMVR), mitral valve-in-valve (ViV), and valve-in-ring (ViR) procedures as well as implantation of transcatheter heart valves in calcific mitral valve disease. These procedures ultimately lead to elongation of the outflow tract into the left ventricle, whereas the pre-existing “nati...

OBJECTIVE To analyze the effectiveness of surgical treatment of atrial fibrillation (AF) using bipolar radiofrequency ablation during mitral valve procedures of rheumatic etiology in heart surgery. METHODS We retrospectively reviewed medical registries of 53 patients submitted to atrial ablation with bipolar radiofrequency energy during mitral valve surgery. Thirty four (64%) patients were wo...

INTRODUCTION AND AIMS The long-term results after surgical repair of rheumatic mitral valve remain controversial in literature. Our aim was to determine the predictive factors which impact the long-term results after isolated rheumatic mitral valve repair and to evaluate the effect of those factors on reoperation and late mortality. METHODS One hundred and four patients with rheumatic valve d...

Transcatheter mitral valve intervention has emerged as an effective treatment option for symptomatic severe mitral regurgitation in patients considered to be inoperable or at high operative risk for surgical mitral valve surgery. Most transcatheter approaches are modifications of existing surgical approaches. Transcatheter edge-to-edge mitral valve repair with the MitraClip system has the large...

BACKGROUND Significant mitral regurgitation in patients undergoing transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The aim of this study is to determine if surgical correction of both aortic and mitral valves in high risk patients with concomitant valvular disease would offer patients better outcomes than TAVR alone. METHODS A retrospective analysis of 43...
