Tricuspid valve (TV) is ‘forgotten’ or ‘enigmatic’ valve. After the surgery of left side valve disease, the longterm follow-up results revealed that the remaining tricuspid regurgation (TR) was not improved but sometimes got worse. We reported our results of tricuspid repair in this study. In Cardiovascular Surgery Clinic of Medical Faculty of Bezmialem Vakif Univercity, from September 2012 to December 2017, 100 patients (male:female 44:56, with a mean age of 61 ± 8.4 for female and; 59 ± 12,6 for male, respectively) underwent tricuspid valve annuloplasty. Operation was performed for functional TR in 98 patients (98%), TV endocarditis in 1 patient (1%), and organic TV disease in 1 patient (1%). The TR was grade II or III in 26 patients (26%) and grade IV in 74 patients (74%). In all patients, 3D-rigid ring was used (29 Carpentier-Edwards Physio Tricuspid annuloplasty ring in 29 patient, and Medtronic Contour 3D ring in 71 patient). Concomitant procedures performed Mitral Repair (48 patients), Mitral valve replacement (MVR) (16 patients), Aort valve replacement (AVR) and Mitral valve replacement (MVR) (16 patients), AVR and MR (7 patients), ASD closure (5 patients), ASD closure + Mitral Repair and Pulmonary valve repair (1 patient), VSD closure (1 patient), Mitral repair and Aort valve repair (1 patient), Mitral repair and Asendan aort replacement (1 patient), Mitral repair and David operation (1 patient), Bentall and CABG (1 patient) Tricuspid Valvotomy (1 patient), İsolated Tricuspid Annuloplasty (1 patient). Hospital mortality was 4 (4%) patients. On early postoperative echocardigraphy evaluation, there was no TR in 68 patients (68%), and mild TR was present in 32 (32%). In functional TR associated with left-sided cardiac valve diseases, TAP might be performed concomitantly, without prolonging operation time significantly and causing additional morbidity.
