A large conus artery in patients with hypertrophic cardiomyopathy.
We retrospectively analyzed coronary arteriograms in 66 patients with hypertrophic cardiomyopathy (HCM) who underwent coronary arteriography. Four of these patients showed a large conus artery supplying the interventricular septum, and the characteristics of their echocardiograms revealed a marked interventricular septal hypertrophy. It is suggested that in some patients with HCM, the conus artery may develop in compensation for the relatively reduced coronary blood flow which is due to the hypertrophied myocardium.
