Abstract
- Rationale and Objectives: To determine the impact of coronary computed tomography angiography (CCTA) on treatment decisions made by cardiac surgeons and to explore barriers to implementation of CCTA as first-line imaging workup before coronary artery bypass. Materials and Methods: Tertiary academic medical center retrospective cohort study. Questionnaires administered to three cardiac surgeons regarding diagnosis and treatment decisions with level of confidence in decision making for 30 chest pain patients, after reviewing deidentified catheter coronary angiogram (CCA) and CCTA images on the same patients, several weeks apart. Results: All surgeons tended to report more severe disease with CCTA than CCA (P < .05). Treatment decisions differed in 12 (40%), 14 (47%), and 18 (60%) patients within each individual surgeon based on CCTA images compared to CCA images (P = .11, .01, and .02, respectively). Confidence levels were significantly higher with CCA for the diagnosis and treatment of coronary artery disease for all three surgeons (P < .05). There was a tendency toward more invasive treatment choices (angioplasty, stent insertion, or coronary artery bypass graft) when making treatment decisions based upon CCTA images. Conclusions: Severity of disease may be overestimated by cardiac surgeons when using CCTA as a decision-making test, tending toward more invasive treatment choices compared to CCA. Additionally, cardiac surgeons may be more confident with their diagnosis and treatment based on CCA. These may be important limitations in the application of CCTA in clinical practice and may reflect the maturation of CCTA use in practice, diffusion of the technology and/or a reflection of the technology itself.
