ABSTRACT
Background:
Transcatheter edge-to-edge repair (TEER) is a less invasive treatment for patients with mitral regurgitation (MR). Limited safety and efficacy data of TEER with MitraClip, including the fourth-generation (G4) system, in a large cohort, are available.Objectives:
This study aimed to summarize the initial experience of the TEER system in patients with MR from a large registry in Japan.Methods:
The OCEAN (Optimized CathEter vAlvular iNtervention)-Mitral Registry is an ongoing, prospective, investigator-initiated, multicenter, observational registry for patients with primary and secondary MR undergoing transcatheter mitral valve therapies. A total of 21 centers participated in the registry. Patients undergoing TEER were enrolled, and their characteristics, procedural details, and clinical outcomes were recorded.Results:
In total, 2,150 patients including 1,605 patients (75.0%) with secondary MR, were enrolled between April 2018 and June 2021. The median age was 80 years, and 43.7% were women. The median device and fluoroscopy times were 60 and 26 minutes, respectively. Those with the G4 system (618/2,150 [28.7%]) were significantly shorter than those with the second generation (G2) system (1,532/2,150 [71.3%]). Overall, 94.6% met acute procedural success without significant differences between the 2 systems (G2 94.7% vs G4 94.6%; P = 0.961).Conclusions:
The OCEAN-Mitral registry has demonstrated the short-term outcomes of TEER systems, including the G4 system, in symptomatic patients with primary and secondary MR. The acute procedural success rate in the G2 system was excellent, and that in the G4 system was expected to improve with the multidisciplinary heart valve team approach.
