Failing DeVega tricuspid valve repair due to detachment of annuloplasty sutures: The Bowstring (Guitar string) sign.

The DeVega annuloplasty procedure involves a double-running suture line along the circumference of the tricuspid annulus, encircling the anterior and posterior leaflets. A rare mechanical complication of this technique is the detachment of the suturing from the annulus, which can be referred to as the "bowstring sign" or "guitar string sign."
