Alfieri versus conventional repair for bileaflet mitral valve prolapse

Figures

• 

  Development of recurrent MR was rare with the Alfieri technique.

  Figure 1. Comparison of long-term survival for patients with bileaflet prolapse repaired with the Alfieri technique (black dashed) and chord/resection technique (grey). Two-year survival was 92% (95% CI, 74%-97%) for patients repaired with the Alfieri technique and 97% (95% CI, 90%-98%) for the chord/resection technique, a difference that was not significant (P = .194).

  Figure 2. Comparison of mean mitral gradient at late echocardiographic follow-up for patients (n = 140) with bileaflet prolapse repaired with the Alfieri technique (black) and conventional chord/resection technique (grey). Median mitral valve gradient was 3 (3-5) for the Alfieri and 3 (3-4) for chord/resection, a difference that was not significant (P = .34).

  Figure 3. Comparison of freedom from recurrent MR (greater than mild) for patients with bileaflet prolapse repaired with the Alfieri technique (black dashed) and conventional chord/resection technique (grey). At 2 years, the cumulative incidence was 4.3% (95% CI, 1.5%-9.3%) for the Alfieri technique and 5.8% (95% CI, 2.2%-11.8%) for the chord/resection technique, a difference that was not significant (P = .83).
