ABSTRACT = {<b>Objective:</b> Anomalous left main coronary artery (LMCA) with an intraconal course is 
a relatively rare form of anomalous aortic origin of a coronary artery (AAOCA) from 
the wrong sinus of Valsalva. There is currently a paucity of information regarding this 
entity. The purpose of this article is to review our surgical experience with repair of 
anomalous LMCA with an intraconal course.<br/>
<b>Methods:</b> This was a retrospective review of 12 patients with an anomalous LMCA 
and an intraconal course who underwent surgical repair. The median age at surgery 
was 15 years (range 2‐47). The seven oldest patients all had preoperative symptoms 
of exertional chest pain and one also had exertional syncope. The five youngest pa‐
tients had no preoperative symptoms. One of these patients had a hemodynamically 
significant ventricular septal defect and one patient was the sibling of a patient who 
had undergone repair of AAOCA.<br/>
<b>Results:</b> The 12 patients underwent surgical repair including unroofing of the myo‐
cardial bridge overlying the intraconal LMCA and a LeCompte procedure. There was 
no early or late mortality and there were no significant complications. All 12 patients 
have resumed normal, unrestricted activities.<br/>
<b>Conclusions:</b> Twelve patients with an anomalous LMCA and intraconal course pre‐
sented to our institution for treatment. Surgical repair was performed successfully in 
all 12, with resolution of symptoms in the 7 patients who were symptomatic preop‐
eratively. These results suggest that the surgical treatment is safe and efficacious in 
patients with an anomalous LMCA and intraconal course.},
