The aim of the study was to assess the clinical and prognostic impact of early functional mitral regurgitation (FMR) improvement on the outcome of patients with idiopathic dilated cardiomyopathy (IDC)….
Comparison of Three-Dimensional Proximal Isovelocity Surface Area to Cardiac Magnetic Resonance Imaging for Quantifying Mitral Regurgitation
The aim of our study was to evaluate 3-dimensional (3D) color Doppler proximal isovelocity surface area (PISA) as a tool for quantitative assessment of mitral regurgitation (MR) against in vitro and…
Safety and Efficacy of Using the Viabahn Endoprosthesis for Percutaneous Treatment of Vascular Access Complications After Transfemoral Aortic Valve Implantation
Vascular access complications (VACs) remain one of the biggest challenges when performing transcatheter aortic valve implantation (TAVI). This study aimed to investigate the short- and medium-term safety and efficacy of…
