Abstract

The right coronary artery (RCA) appears either C-shaped or sigma-shaped during standard angiography. The purpose of the present investigation was to assess whether C-shaped RCAs are associated with more atherosclerotic disease than sigma-shaped RCAs. The study sample comprised 120 consecutive patients who underwent coronary catheterization and multivariate analysis was conducted using several systemic risk factors for atherosclerosis. The proportion of sigma-shaped RCAs found in a group whose angiograms showed little or no obstruction (70%) was significantly higher than that found in the group with significant obstruction (33%, p <0.001). In conclusion, a C-shaped RCA is associated with atherosclerosis.
