Objective To utilize a rapid health technology assessment to evaluate the efficacy, safety and cost-effectiveness of the MitraClip device for patients with severe mitral regurgitation (MR). Methods PubMed, EMbase, The Cochrane Library, CNKI, WanFang Data, CBM and the CRD databases were electronically searched to collect clinical evidence and economic evaluations on the efficacy, safety and cost-effectiveness of the MitraClip device for patients with severe MR from inception to May 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; then, descriptive analyses and data summaries were performed. Results A total of 33 studies, involving 4 HTA reports, 3 RCTs, 16 systematic reviews or meta-analyses, and 10 economic evaluations were included. In the evidence comparing MitraClip and surgery, most of the literature showed that the MitraClip group had higher postoperative residual MR, fewer blood transfusion events, and fewer hospital days. We found no significant treatment effects on 30-day adverse events and mortality, and the 1-year and above survival rate. In the evidence of MitraClip versus medical therapy alone, all included studies showed that MitraClip benefited mid-term and long-term survival and reduced the incidence of subsequent cardiac hospitalizations. Economic evaluations showed that the clinical benefits were cost-effective in the setting of their health service systems. Conclusion The available high-grade clinical evidence shows that MitraClip is effective and safe to some extent, and has cost-effectiveness compared with traditional treatment in other countries. However, the real-world effectiveness and cost-effectiveness of the MitraClip need to be tested in the Chinese population and health-care setting.
