A simplified sliding plasty technique combined with ring annuloplasty and commissuroplasty can successfully repair an unguarded tricuspid orifice.
Simplified sliding plasty with annuloplasty may repair unguarded tricuspid orifice; extends options but leaves open generalizability pending larger studies.
Unguarded tricuspid orifice is a rare anomaly of the tricuspid valve characterized by complete absence of tricuspid valve tissue and chordae on a proportion of the annulus. Management strategies vary widely. We report a case of successful repair of an unguarded tricuspid orifice with a simplified technique. A 35-year-old male presented with severe tricuspid regurgitation and right ventricular volume overload. Intraoperative inspection of the valve revealed an unguarded tricuspid orifice. For repair, sliding plasty of anterior and posterior leaflets were performed, followed by ring annuloplasty and commissuroplasty. Postoperative, echocardiogram showed minimal residual tricuspid regurgitation and significantly improved right ventricular dimensions. This case highlights the possibility of successful repair of an unguarded tricuspid orifice. If feasible, repair can be a good choice.

Zegel et al. (2026) conducted a case report in Unguarded tricuspid orifice (n=1). Sliding plasty of anterior and posterior leaflets, ring annuloplasty, and commissuroplasty was evaluated on Residual tricuspid regurgitation and right ventricular dimensions. Sliding plasty of anterior and posterior leaflets combined with ring annuloplasty and commissuroplasty successfully repaired an unguarded tricuspid orifice with minimal residual regurgitation.
