OBJECTIVE: Significant proportion of patients with advanced heart failure presents with dilated left ventricles (LVs) and functional mitral regurgitation (FMR). These patients currently have limited treatment options. MitraClip has benefited patients only with a smaller LVs (End-diastolic dimension<70mm), whereas those with larger LVs did not benefit. A possible explanation is correcting FMR alone may not adequately reduce the wall stresses of a dilated LV. We have developed a beating heart device that approximates the papillary muscles to reduce FMR, but also modifies the LV size and shape to reduce wall stress...

Microinvasive cardiac surgery includes procedures performed off-pump, on the beating heart, with limited or absent skin incision, and those that rely on live imaging techniques. Transapical off-pump beating heart neochordae implantation allows the repair of severe mitral valve regurgitation due to leaflet prolapse or flail with live three-dimensional echo guidance. This procedure has shown good results for up to 5 years and can be considered as a valid alternative to conventional surgery in selected patients with high prediction of success based on clinical and anatomical considerations...

BACKGROUND: Percutaneous transvenous mitral commissurotomy (PTMC) is one of the non-surgical methods for patients with significant mitral stenosis. It is less invasive, less complicating with better outcomes compared to surgery. The Wilkins score ≤8 is used to select patients for PTMC, but the results of several studies suggest that PTMC can also be successful in a higher Wilkins score. The aim of this study is to compare the outcomes of PTMC between two groups. METHODS: In this retrospective study, patients who underwent PTMC between April 2011 and December 2019 were included...

Mitral regurgitation (MR) was the most common heart valve disease. Surgical repair with artificial chordal replacement had become one of the standard treatments for mitral regurgitation. Expanded polytetrafluoroethylene (ePTFE) was currently the most commonly used artificial chordae material due to its unique physicochemical and biocompatible properties. Interventional artificial chordal implantation techniques had emerged as an alternative treatment option for physicians and patients in treating mitral regurgitation...

Hypertrophic obstructive cardiomyopathy is a disease of the heart in which the patient develops left ventricular outflow tract obstruction due to the interaction of the mitral valve and the intraventricular septum. Although septal myectomy remains the gold standard treatment for hypertrophic obstructive cardiomyopathy, several other approaches have been described in the literature, such as a transaortic, transapical or transmitral approach via a sternotomy. All of these approaches have been shown to produce reliable reduction in left ventricular outflow tract gradients...
