[Transcatheter edge-to-edge repair using MitraClipTM G4 for severe mitral regurgitation in an advanced elderly patient with Barlow disease].

Abstract

A 91-year-old male patient was admitted with a history of mitral valve prolapse diagnosed by physical examination ten years prior and recent onset of exertional chest discomfort persisting for over one month. Transthoracic echocardiography showed that the anterior leaflet of mitral valve was thickened and prolapsed with severe regurgitation, and transesophageal echocardiography further confirmed that the anterior and posterior leaflets of mitral valve were prolapsed with massive regurgitation (A1, A2, A3, P1 and P2 were all prolapsed). Thus, the diagnosis of Barlow syndrome was considered. Transcatheter edge-to-edge mitral repair was performed with two MitraClip^TM G4 XTWs. After a 10 months follow-up, the patient's cardiac function was significantly improved, and the degree of mitral regurgitation was mild.
