Echocardiographic and Clinical Outcomes of Central Versus Noncentral Percutaneous Edge-to-Edge Repair of Degenerative Mitral Regurgitation [1]
Percutaneous edge to edge repair with MitraClip is typically used in situations of central mitral insufficiency (MI). In this study, the authors evaluate the applicability of this technique in non-central MI. They have carried out a retrospective analysis of their own results in a group of 79 patients. Although patients with non-central MI had higher pulmonary pressures and wider basal vena contracta, there were no significant differences in procedural success or complications. In addition, there were no significant differences in all-cause mortality, readmission for heart failure, residual MI and NYHA status at 1 and 6 months. Although the study is probably too small in size as to provide strong evidence, the results suggest that non-central MI could be amenable to treatment with percutaneous edge to edge repair techniques.
