Surgical Decision-Making for Concomitant Tricuspid Valve Repair in Minimally Invasive Mitral Valve Surgery

As minimally invasive mitral valve surgery (MIMVS) continues to gain acceptance, concomitant tricuspid valve (TV) repair in patients with significant tricuspid regurgitation (TR) is increasingly encountered. The authors explored the current practice patterns regarding TV repair during MIMVS and found that, generally, the indications for TV repair were followed, although there were institutional variations. Key reasons for omitting TV repair included absence of severe tricuspid regurgitation (odds ratio 3.31 for moderate TR, OR 4.06 for mild TR), a lower NYHA class (OR 0.61 for NYHA III-IV), and mitral valve disease type (OR 0.38). TV repair was associated with longer ICU (48 vs 23 hours, P
