Repairing Tricuspid valve During MV Surgery prevents Tricuspid Regurgitation progression

Key findings of the study:

• Upon analysis, the researchers noted that 40% of patients with moderate TR who underwent concomitant tricuspid valve surgery had their TR grade reduced to mild and 50% had only trivial or no TR at all in early postoperative TTE follow-up.
• Among those untreated, they noted that 6.6% had severe TR, 43.6% had moderate TR, and 34.6% had mild TR on postoperative TTE.
• Compared with patients who didn't have moderate TR treated during surgery, they found that the probability of worsening TR increased with time and these trends were generally similar for all of the preoperative [TR] grades.

Regarding the long-term follow-up, those who had moderate TR treated during MV surgery had generally a similar risk or probability of moderate or greater TR at 5, 10, and 15 years, said Hasan. She further added, "Interestingly, the risk of progression to severe TR was not influenced by the size of tricuspid annulus diameter, but a diagnosis of preoperative congestive heart failure was associated with severe TR progression."
