I prefer the MitraClip in these cases: the 5-year COAPT data

The COAPT 5-year data demonstrate that compared with medical treatment transcatheter edge-to-edge repair (TEER) with the MitraClip in symptomatic patients with Grade 3+/Grade 4+ secondary mitral regurgitation (SMR) reduced by nearly half the annualized hospitalization risk (33 vs. 57%), by almost 30% the death rate (57 vs. 67%) and achieved significant and durable SMR reduction in 95% of patients. Control patients who crossed over to TEER at 2 years had better prognosis, but nearly half of them died before reaching crossover eligibility. Death or hospitalization for heart failure (HHF) occurred in 73.6% of TEER patients and 91.5% of controls within 5 years, pointing to a need for further study to address left ventricle (LV) dysfunction, the underlying cause of patient's disease. MTRA-FR targeted SMR using the same device and did not improve the composite endpoint of all-cause mortality or HHF at 12 months. Possible reasons for the discrepancy include enrolment of patients with more severe MR and less-advanced LV disease (dilation/dysfunction), less-procedural complications, and higher success in reducing MR in COAPT compared with MITRA-FR. Thus, the ideal patient for MitraClip treatment would be one with severe MR, but with no too severe LV dilation/dysfunction, which is what differentiates COAPT patients from those in MITRA-FR.
