Right coronary artery agenesis – case report

Abstract

The following study presents a 75-year-old female patient who was admitted to the hospital due to atypical chest pain and paroxysmal dyspnoea. After imaging and laboratory diagnostics, the absence of the right coronary artery (RCA) was confirmed. A solitary coronary artery is a relatively rare congenital anomaly with a not fully understood aetiology. Most patients remain asymptomatic throughout their lives, while some may experience nonspecific symptoms such as chest pain or decreased exercise tolerance. These patients are initially diagnosed with coronary artery disease, which delays the recognition of RCA absence. The gold standard for diagnosing the absence of RCA is cardiac computed tomography (CT). Treatment is primarily conservative, but in cases requiring intervention, surgical treatment is utilized.
