Limitations
Due to the retrospective nature of this study, the hemodynamic data limited to what was documented in echocardiography reports. We did not evaluate interobserver variability by independent review of hemodynamic parameters. As such, we were unable to account for effects of BAV morphology (i.e. cusp fusion pattern, presence of raphe) as they were inconsistently reported on. In addition, this was a single center study, which limits generalizability and raises the possibility of not capturing outside imaging and operative records, though an extensive chart review was conducted using our electronic medical record. Lastly, the power of statistical conclusions drawn from this sample are limited by the sample size of the BAV cohort. Our findings warrant future multicenter studies in order to achieve larger a sample of BAV patients.
