Abstract
Endovascular interventions for cardiovascular pathology are becoming increasingly relevant tocardiothoracic surgery. This study assessed the perceived prevalence and efficacy of endovascular skills training and identified differences among training paradigms. Trainee responses to questions in the 2016 In-Service Training Examination survey regarding endovascular training were analyzed based on the four different cardiothoracic surgery training pathways: traditional 2- and 3-year thoracic, integrated 6-year, and combined 4+3 general and thoracic residency programs. The duration of endovascular training was substantially different among programs, at a median of 17 weeks for integrated 6-year, 8.5 weeks for 3-year, 6 weeks for 4+3, and 4 weeks for 2-year residency (p < 0.0001). After adjusting for year of training and program type, the duration of endovascular rotations was significantly associated with self-assessed comfort with catheter-based skills (p < 0.0001). Eighty-two percent of residents rotated with trainees from other specialties, and 58% experienced competition for cases. Residents reported greater exposure to transcatheter aortic valve replacement than to thoracic endovascular aortic repair, cardiac catheterization, percutaneous closure of atrial septal defect, and transcatheter mitral valve surgery (p < 0.0001). A significant proportion of responders reported feeling uncomfortable performing key steps of transcatheter aortic valve replacement (52%) or thoracic endovascular aortic repair (49%). Considerable heterogeneity exists in endovascular training among cardiothoracic surgery training pathways, with a significant number of residents having minimal to no exposure to these emerging techniques. These findings highlight the need for a standardized curriculum to improve endovascular exposure and training.
