The authors report an exceptionally rare patient with findings of a bicuspid aortic valve in conjunction with a mature cystic teratoma in a middle-aged male presenting for symptomatic chest pain. Surgical resection and valve replacement were performed, confirming the rare cardiac tumor. While certainly interesting, this case highlights the importance of maintaining a broad differential diagnosis and the appropriate work-up, treatment and considerations for such rare pathology.

In this issue, Zhao et al. investigate the effects of subclinical hypothyroidism in coronary bypass grafting particularly with respect to the incidence of atrial fibrillation. While not the first of its kind, the authors analyze this controversial topic in a well powered, statistically comprehensive manner that furthers our understanding of the effects of SCH in CABG patients.
