A therapeutic challenge in complete coronary occlusion identified by computed tomography: Double aortic arch

A 57-year-old male with known history of obstructive sleep apnea was admitted for shortness of breath. On exam, patient was tachycardic with increased jugular venous pressure. Electrocardiogram showed sinus tachycardia with right ventricular strain and ST-segment depressions in the lateral leads. A computed tomography pulmonary angiography (CTPA) demonstrated no evidence of pulmonary embolism. Incidentally, a double aortic arch (DAA) was noted on CTPA (Fig. 1, Fig. 2). On laboratory exam, the patient had elevated troponin I at 0.276 ng/mL.
