Background: Little is known about gender differences among patients undergoing percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). Methods: A total of 242 patients underwent 255 procedures PCI of CTO in our center between January 2011 and January 2015. Demographic data, procedural differences and success rate beetwen genders was compared. Result: Among 242 treated patients 16,9% (n=41) were women. Women were older than men (67.8±8.4 vs.61.3±9.0, p<0.005, respectively). There were no differences in diagnosis of hypertension (92.7% vs.85.6%), dyslipidaemia (100% vs. 99%) or diabetes (34.2% vs.28.4%)(p=NS). Less women were current smoker (7.3% vs. 23.4%, p<0.005). 46.1% of women and 50.8% of men suffered from myocardial infarction before procedure (p=NS). The most frequently opened artery in both groups were right coronary artery (45.2% vs.49.8%), then left anterior descending artery (40.5% vs. 31.5%) (p=NS). Occlusion’s characteristic did not differ in both groups in estimated duration (10.9±19.5 vs. 16.6±33.1 months) and length (27.0±14.0 vs. 26.9±11.8 mm), (p=NS). Retrograde technique was used in 10 women (23.8%) and in 46 men (21.6%) (p=NS). Time of procedure (minutes) (71.4±27.9 vs. 69.3±.33.4), fluoroscopic time (minutes) (25.7± 15.2 vs. 26.9±18.4) and contrast volume (ml) (370.8± 170.2 vs. 348.3±156.7) did not differ beetwen women and men (p=NS for all). Overall succes rate was 86.7%, in women 80.9% and in men 87.9% (p=NS). Conclusion: PCI of CTO remains safe and successful method of revascularization in men and women. However, women were a significant minority. Although women are older, success rate of revascularization and complications were similar compared to men.
