Unusually looped and muzzled branches of right coronary artery
Coronary artery disease (CAD) is the major cause of death in developed countries as it accounts on an average for 1 of every 5 deaths. Morphological variations of coronary arterial system is one of the causative factor for CAD. Anatomical knowledge of all possible variant patterns of coronary arterial system is imperative in the diagnostic and therapeutic approach of CAD. We report here a rare branching pattern of right coronary artery (RCA). The origin of RCA was normal but the course and branching pattern of it were atypical. RCA was not occupying its usual position in atrioventricular (coronary) sulcus and its course was incomplete. It gave a ventricular branch to right ventricle, which presented an unusual looping pattern. It terminated as right marginal artery following its muzzled appearance within the musculature of the ventricle.
The aim of our study is to characterize, using OCT, the morphologic features of calcific plaques after rotational atherectomy, adjunctive balloon angioplasty and stenting. ::: ::: A total of 57 consecutive patients who had undergone angioplasty using rotational atherectomy were included. The 67 lesions
