Background and Aim Second‐order chord tethering of the anterior leaflet is a risk factor for failure of posterior leaflet prolapse repair. Materials and Methods We describe two cases of second‐order chord tethering of the anterior leaflet associated with severe mitral regurgitation due to prolapse or chordal rupture of the anterior leaflet, causing early and late failure of repair. Results We described two cases where this phenomenon happened. Conclusions Our cases demonstrate that the second‐order chords of the prolapsing AL can be tethered and that this aspect should be carefully evaluated before surgery, as it can progress over time, affecting the results of surgical repair.
