title: From tricuspid to double orifice Morphology: Percutaneous tricuspid regurgitation repair with the MitraClip device in congenitally corrected-transposition of great arteries.
abstract: Edge to edge transcatheter mitral valve repair with MitraClip (Abbott Vascular, Menlo Park, CA) is increasing for high-risk surgical patients with significant mitral regurgitation. Patients with congenitally corrected transposition of the great arteries (CCTGA) presenting with tricuspid valve regurgitation of a systemic right ventricle may represent particularly challenging candidates for MitraClip given their anatomy. We report the case of a 67-year-old gentleman with CCTGA and severe tricuspid regurgitation who was referred for MitraClip implantation after heart team consensus. Successful implantation of one clip was performed, achieving a significant reduction of the regurgitation. Similarly, favorable findings were confirmed at 6 months, 1 and 2 years follow-up and the patient had no recurrent heart failure admissions after 2-year follow-up. We describe the technical considerations and the importance of 3D-transoesophageal echocardiography for performing the MitraClip of a trileaflet systemic atrioventricular valve. © 2016 Wiley Periodicals, Inc.
