Reconstruction of an Unguarded Tricuspid Orifice Using a Simplified Sliding Plasty Technique

Year: 2026

Type: article

Abstract: 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 the anterior and posterior leaflets was 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.
