A Case of an Anomalous Right Coronary Artery Arising from the Left Coronary Cusp

Abstract

An anomalous origin of the right coronary artery is usually asymptomatic. It is mostly found incidentally on an invasive diagnostic angiogram. It does lead to an increased risk of sudden cardiac death, especially in younger patients. We present a case of a 41-year-old who had presented to the hospital with complaints of chest pain. The patient was evaluated by cardiology who performed an angiography that identified an anomalous origin of the right coronary artery arising from the left coronary cusp but no evidence of coronary artery disease. Once identified, these anomalous vessels should be corrected surgically, as these conditions increase the risk of sudden cardiac death arrhythmia and ischemic events.

Coronary Artery Disease in Patient with An Anomalous Origin of Right Coronary Artery

“…The treatment of ARCA is often controversial. Surgery is recommended in symptomatic patients, and conservative management in asymptomatic patients (Rawala et al, 2019). Treatment options include observation with medical therapy, percutaneous intervention (stenting), or surgery (Vora et al, 2021).…”

“…An anomalous origin of the right coronary artery is usually asymptomatic (Villa et al, 2016). It is mostly found incidentally on an invasive diagnostic angiogram (Rawala et al, 2019). The incidence of an anomalous right coronary artery originating from the left coronary sinus on coronary angiography is 0.019% to 0.49%.…”
