Abstract
Aim: Bicuspid aortic valve (BAV) is one of the most common congenital cardiac malformations, with increased risk for early onset thoracic aortic aneurysms (TAA). This study aims to examine the trends over time in incidence of BAV patients with TAA, given imaging advancements and increased frequency of imaging.
Methods: Using administrative billing codes, this retrospective cohort study analyzed New York Statewide Planning and Research Cooperative System records from January 2007- December 2018, evaluating BAV+TAA incidence trends. Subgroups based on index admission were evaluated with a pre-identified 2014 inflection time point using an interrupted time series (ITS) analysis.
Results: Using a New York State-wide billing database, 3,294 BAV and TAA first-time encounters were classified into three diagnosis-related patient sub-groups, as patients with: historical BAV + new TAA diagnoses (24.74%); new BAV + historical TAA diagnoses (27.57%); and new BAV + new TAA diagnoses (47.69%). Total BAV and TAA diagnostic incidence increased from 7.93/1,000,000 residents in 2007, to 24.75/1,000,000 residents in 2018 (overall annual rate of 17.91/1,000,000, p< .001). With a pre-established 2014 inflection point, the incidence rate dramatically changed for new BAV+ new TAA patients (slope = 0.7592, 95% CI 0.2332-1.2851).
