BACKGROUND
A 61-year-old woman presents to the hospital with a change in her voice. Laryngoscopy reveals complete vocal cord paralysis on the left side. Her past medical history is significant for hypertrophic obstructive cardiomyopathy (HOCM). She has an implantable cardiac defibrillator in place. Imaging studies of the thorax reveal the cause of the problem.
Hint
Take a look through the aortopulmonary (AP) window.
