Percutaneous edge-to-edge mitral valve repair can be performed safely, and reductions in mitral regurgitation can be achieved in a significant proportion of patients. However, complications can arise in a minority of patients. The authors report three cases in which complications of percutaneous mitral valve repair were documented by real-time three-dimensional transesophageal echocardiography. This new imaging technique provides real-time, easily understandable images of valve anatomy and the percutaneous mitral valve repair procedure, which helps guide the decision-making process.
