| 2 | Catheter-based intervention for symptomatic patient with severe mitral regurgitation and very poor left ventricular systolic function-Safe but no room for complacency显示文摘Many patients with left ventricular systolic dysfunction have concomitant mitral regurgitation(MR). Their symptoms and prognosis worsen with increasing severity of MR. Percutaneous Mitra Clip® can be used safely to reduce the severity of MR even in patients with advanced heart failure and is associated with improved symptoms, quality of life and exercise tolerance. However, a few patients with very poor left ventricular systolic function may experience significant haemodynamic disturbance in the peri-procedural period. We present three such patients, highlighting some of the potential problems encountered and discuss their possible pathophysiological mechanisms and safety measures. | Poay Huan Loh Christos V Bourantas Pak Hei Chan Nikolaj Ihlemann Fin Gustafsson Andrew L Clark Susanna Price Carlo Di Mario Neil Moat Farqad Alamgir Rodrigo Estevez-Loureiro Lars SΦndergaard Olaf Franzen | 2015 | World Journal of Cardiology2015，7，11： | 0 |
