Surgical Techniques for Secondary TR<br />
• (A) Dilated tricuspid annulus with abnormal circular shape, failure of leaflet coaptation, and<br />
resultant TR. Dilation occurs primarily along the mural portion of the tricuspid annulus, above<br />
the right ventricular free wall<br />
• (B) Rigid or flexible annular bands are used to restore a more normal annular size and<br />
shape (ovoid), thereby reducing or eliminating TR<br />
• (C) DeVega–style suture annuloplasty in which a purse-string suture technique is used to<br />
partially plicate the annulus and reduce annular circumference and diameter<br />
• (D) Suture bicuspidalization is performed by placement of a mattress suture from the<br />
anteroposterior to the posteroseptal commissures along the posterior annulus<br />
