Management of anomalous coronary arteries from the contralateral sinus.
Anomalous origin of the coronary artery from the contralateral sinus of Valsalva, coursing between the aorta and pulmonary artery, has garnered much attention because of its association with sudden death. Current medical opinion is heavily skewed toward "successful" intervention. However, two key issues have not been critically analyzed: what is the true risk of sudden death from an anomalous coronary artery, and how does this risk balance against the risk of surgical intervention? Common misconceptions about risk derive from citations of autopsy data. In fact, the scant available data suggest a far lower absolute risk than commonly cited. The risks of surgical intervention, while likely quite low, remain real, and include aortic valve damage and neurological sequelae. The lack of long-term outcomes data precludes any definite recommendations in most patients. The decision to intervene is thus not straightforward, and should be approached cautiously and only after appropriate counseling of the patient.
