Abstract:
Objective·To analyse the outcomes of tricuspid valve replacement (TVR) for secondary tricuspid regurgitation (STR) late after left-sided valve surgery during perioperative period and mid-term follow-up,investigate mechanisms of STR and surgical risk factors.Methods·A total of 85 consecutive patients who underwent the TVR surgery were analyzed.The perioperative and mid-term clinical outcomes were retrospectively investigated.The data were divided into bioprosthesis group (n=50) and mechanical prosthesis group (n=35) according to the prosthesis used,and divided into right anterolateral thoracotomy(RALT) group (n=51) and stemotomy(S) group (n=34) according to the surgical incision.Results·In-hospital mortality was 8.2％ (7/85).There was no significant difference in the mortality with different choice of bioprosthetic or mechanical valve (4/50 vs 3/35,x2=0.009,P=1.000);while there was significant difference between S group and RALT group (6/34 vs 1/51,x2=6.642,P=0.015).Seven cases all died of right heart failure and severe low cardiac output syndrome.Five (5.9％) cases died in perioperative within 30 in-hospital days and 2 (2.4％) cases died after 30 in-hospital days.Seventy-four cases were followed up.With the follow-up of (31.5±23.1) months,there were 4 case of late deaths(5.4％),all of whom were mechanical prosthesis,of whom 3 died in cardiac related death and 1 died in later period bowel cancer.Seventy cases survived in New York Heart Association (NYHA) class Ⅰ-Ⅱ with no coagulated accident and redo-TVR.Conclusion·The perioperative and mid-term clinical outcomes are satisfied in timely and reasonable TVR with the standard follow-up for STR late after left-sided valve surgery.Right anterolateral incision is recommend for isolated TVR.
