Abstract
To determine the incidence of, and predictive factors for, aortic autograft failure during follow-up after the Ross procedure. Of 102 consecutive patients who underwent surgery at our centre between 1997 and 2009, we selected 83 (age 32±11 years), all of whom had been discharged without significant autograft regurgitation and for whom at least one follow-up echocardiogram was available. Autograft failure was defined as the presence of at least moderate regurgitation on echocardiography. After a median follow-up period of 4.2 years (range 0.2-10.9 years), eight patients (9.6%) developed this complication, three of whom required valve replacement. The probability of survival without autograft failure at 5 years was 90% (95% confidence interval [CI] 83%-98%). Multivariate analysis showed that undergoing surgery during the first 6 months of the learning curve (hazard ratio = 9.1; 95% CI, 1.4-59.4; P=.021) and a large pulmonary annulus size, normalized by body surface area, (hazard ratio = 1.4; 95% CI, 1.016-1.924; P=.04) were independent predictors of this complication.
