We sought to determine whether the chronic total occlusions (CTO) recanalization results differ between circumflex artery (CX) and other coronary arteries in our center. The study dataset encompassed 428 consecutive procedures. J-CTO score was highest in the right coronary artery (RCA) and lowest in CX lesions. After adjusting for the J-CTO score, age, body mass index, baseline creatinine, diabetes, dyslipidemia and hypertension the odds ratio for procedural success in CX compared to the other arteries was not statistically significant. We found no difference in success rates of recanalizing CTO in CX compared to other coronary arteries.
