We report the case of a 68-year-old patient with severe tricuspid regurgitation who had previously undergone aortic valve replacement and right coronary artery bypass. We performed tricuspid valvuloplasty via the right parasternal route in order to reduce surgical trauma by avoiding resternotomy, trauma to the venous graft, and bleeding due to dissection of old adhesions. The patient's postoperative course was uneventful, and he was discharged home on the 7th postoperative day.
