Fig 1 Surgical technique for repair of bicuspid aortic valve. (A) Repair sutures for most repairs. (B) Mobilization of commissures for a large root. (C) Closure of gaps in aortic root. (D) Reattachment of commissures resuspended at a higher level in ascending aorta tube graft.

Fig 2 Freedom from aortic valve reoperation after repair of bicuspid aortic valve. Each symbol (○) represents a reoperation positioned nonparametrically, vertical bars are confidence limits equivalent to ±1 standard error, and numbers in parentheses are patients still alive. Solid line is parametric estimate enclosed within dashed 68% confidence band equivalent to ±1 standard error.

Fig 3 Reasons for reoperation and the reoperative procedures performed. (AR = aortic regurgitation; AS = aortic stenosis; AVR = aortic valve replacement; CABG = coronary artery bypass grafting; MVR = mitral valve replacement.)

Fig 4 Aortic valve regurgitation (AR) across time after aortic valve repair. Circles represent grouped data without regard to repeated measurements. Solid lines are model-based estimates that account for repeated measurements.

Fig 5 Aortic valve (AV) gradient after repair of bicuspid aortic valve disease. Circles represent grouped data without regard to repeated measurements. Solid lines are model-based estimates. Preoperative (Preop) values shown as a bold dot. (A) Mean gradient. (B) Peak gradient.

Fig 6 Left ventricular (LV) mass index after aortic valve repair for bicuspid disease. Circles represent grouped data without regard to repeated measurements. Solid line is model-based estimate. Late increase in LV mass index is about 0.85 g/m2 per year. Preoperative (Preop) value shown as a bold dot.

Fig 7 Survival after aortic valve repair for bicuspid aortic valve disease. Each symbol (○) represents a death positioned nonparametrically, vertical bars are confidence limits equivalent to ±1 standard error, and numbers in parentheses are patients still alive. Solid line is parametric estimate enclosed within dashed 68% confidence band equivalent to ±1 standard error. Dash-dot-dash line represents survival of an age-sex-race–matched US population life table.

Fig 8 Survival stratified by New York Heart Association (NYHA) functional class. Each symbol represents a death positioned on a vertical axis by the Kaplan-Meier estimator, vertical bars are 68% confidence limits equivalent to ±1 standard error, and numbers in parentheses are number of patients still alive and being traced.
