An unusual cause of intractable cough

摘要

An 82-year-old man was referred for coronary tomography angiography (CTA) following a 3-month history of symptoms of shortness of breath and intractable cough. This demonstrated a massive (35 mm), highly tortuous, and calcified right coronary artery (RCA) that followed a serpentine course over the anterior aspect of the heart (Figure 1A), before draining into the inferior aspect of a massively dilated coronary sinus (Figures 1B and C; RCA-coronary sinus fistula).
