Aberrant origin of the right coronary artery: diagnostic and surgical aspects

A 43-year-old man with angina for 15 years underwent coronary angiography,
which showed an anomalous origin of the right coronary artery (RCA) from
the left sinus of Valsalva with a 30-40% fibrous stenosis in the proximal
part of the artery, which was presumably responsible for the patient's
symptoms. Myocardial scintigraphy (Tc-99 m Cardiolite) suggested reversible
ischemia at the apex and the posterior wall of the ventricles. After
coronary bypass and anastomosis of the right internal mammary artery (RIMA)
to the middle segment of RCA, the patient was asymptomatic; however, a
postoperative myocardial scintigraphy indicated that the myocardial
ischemia was irreversible.
