Although surgical management is associated with improved outcomes, the optimal approach remains to be elucidated. We describe a case of AEF which was treated with a simultaneous repair of the atrium and esophagus via a right thoracotomy with an extra-pericardial off-pump approach. Kommerell diverticulum (KD) is a dilated proximal aberrant subclavian artery associated with either right or left aortic arches (RAA-ARSA or LAA-ALSA). Although case series suggest KD may be a liability for vascular complications, the risk, pattern of dilation throughout the lifespan, and differences between arch sides, are not known. A single-center retrospective review of patients of all ages with KD on cross-sectional imaging. Maximal short axis diameter of KD (KDmax), absolute and indexed to descending aortic (DAo) diameter, was correlated with age. Comparisons were made between arch sides. Patients with vascular complications are described. One hundred and four patients with KD were included [68 (65%) RAA-ALSA, 36 (35%) LAA-ARSA; 43 (41%) asymptomatic]. Although KDmax was correlated with age (RAA-ALSA r=0.84 [p<.0001]; LAA-ARSA r=0.51 [p=0.001]), KDmax/DAo was not (RAA-ALSA r=0.14 [p=0.27]; LAA-ARSA r=-0.22 [p=0.21]). RAA-ALSA had larger KDmax/DAo (1.02±0.20 vs 0.89±0.18 mm/mm, p=0.002), more sy patients with LAA-ARSA and aneurysm risk factors. This suggests conservative management of asy
