Transcatheter tricuspid valve edge-to-edge repair for severe tricuspid regurgitation in a Chinese patient.

An 80-year-old man with recurrent right heart failure despite optimal heart failure therapy, was referred to our institution. He had inferior myocardial infarction, had undergone a coronary artery bypass graft operation and had a permanent pacemaker. Echocardiography showed a dilated right ventricle with impaired systolic function (Tricuspid annular plane systolic excursion (TAPSE) 10 mm), a dilated tricuspid annulus (septal-lateral diameter 4 cm) and massive (4+) functional tricuspid regurgitation (TR) (figure 1A). The tricuspid valve (TV) was structurally intact without impingement or perforation by the pacemaker lead (figure 2A,B). The heart team did not consider him fit for open repair because of the previous sternotomy and his frailty (score 6/9),1 and recommended percutaneous edge-to-edge TV repair with the MitraClip device. Figure 1 (A) Colour flow Doppler of tricuspid valve (TV) from the apical four-chamber view: massive tricuspid regurgitation (TR) with an effective regurgitation orifice (ERO) was 0.35 cm2 …
