OBJECTIVES: Evaluate the incidence of various morphologic types of congenital AS, and the association between valve morphology and long-term outcomes, including repeat BAV, AVR, and death/transplant. BACKGROUND: Reports on long-term outcomes have low agreement on the influence of morphologic type. METHODS: We queried our institutional database and hospital billing records to identify all patients who underwent balloon aortic valvuloplasty (BAV) from 1992 through 2009. We excluded cases where morphology was not clear based on the description in the pre-BAV echocardiogram report and patients who underwent single ventricle palliation. The primary outcome of the study was the occurrence of any of the following events: repeat valvuloplasty, AVR, heart transplant, or death. RESULTS: There were 147 patients in our study cohort. The most common morphology was functionally bicuspid (n = 92, 63%), followed by functionally unicuspid (n = 20, 14%), dysplastic (n = 16, 11%), true bicuspid (n = 13, 9%), and true unicuspid (n = 6, 4%). The primary endpoint was less likely to occur in patients with functionally bicuspid valves (P < 0.01) and patients with true bicuspid valves (P = 0.03), whereas it was more likely to occur in patients with functionally unicuspid valves (P = 0.02) and patients with true unicuspid valves (P = 0.05). Multivariate Cox regression analysis demonstrated that valve type other than functionally bicuspid was associated with diminished freedom from repeat intervention, death or transplant (HR 3.3, CI 1.2 - 8.6, P = 0.02). CONCLUSIONS: In our cohort, patients with functionally bicuspid aortic valves, the most common type, had improved outcomes as compared with all other morphologic types. © 2012 Wiley Periodicals, Inc.
