BACKGROUND: Shepherd's crook deformity of right coronary artery is considered hemodynamically nonsignificant course anomaly. It may be challenging for cardiologist during percutaneous transluminal coronary angioplasty. : AIM: To investigate the radiological anatomy of the high riding course of the proximal segment of the right coronary artery (RCA), especially focused on the Shepherd's crook right coronary artery (SCRCA) on multidetector computed tomography (MDCT) coronary angiography.
METHODS: A total of 1118 MDCT coronary angiography examinations were reviewed retrospectively (349 [%31.2] male; 769 [%68.8] female, age ranged from 18 to 88 years [54.4±14.7 years, mean±SD]). We classified the segments that had a higher course than RCA ostium (high riding RCA) into two types: Type 1; courses turning inferior with an angle equal to or more than 90 degrees, Type 2 (SCRCA); courses turning inferior with an angle less than 90 degrees. The origin of the sinoatrial node artery (SANA) and conus artery (CA) were also noted.
RESULTS: High riding RCA was detected at 146 patients (%13). Of them, 105 (%71) had type-1 and 41 (%29) had type-2. Atherosclerotic plaque formations to varying degrees were presented at 10 (%24,3) of the patients with SCRCA. Approximately half of SANA was originated from SCRCA segment of RCA in SCRCA cases.
CONCLUSIONS: This is the first study about SCRCA which have been performed with MDCT coronary angiography. This study brings a few important anatomical knowledge to cardiologists. To have knowledge about the origin of the SANA prior to PTCA procedures is important to prevent possible arrhythmias and infarcts.
