Abstract

Objective: Coronary angioplasty in bifurcation lesions has lower success rate and more complications than other lesions. We performed this study to define early complications of angioplasty in these lesions and to find the predictive factors of major side branch (more than 1 mm) occlusion. Methodology: In this study, 104 consecutive patients with bifurcation lesion in a single center were evaluated. The. side branches were classified based on diameter and morphology of the lesions. Results: In 41 (39.4) patients side branch compromise (SBC) occurred. In patients with SBC 34.1 had chest pain and in 3 (2.9) patients non-Q wave myocardial infarction (MI) occurred, all after SBC. The incidence of non-Q wave MI after SBC was 7.3. The probability of SBC in patients with ostial lesion of more than 50 was significantly higher (p=0.021) than patients without such a lesion. Also, if the main branch lesion was more than 80; SBC was significantly higher (p=0.011) than patients without such lesions. Using multiple logistic regression analysis, only more than 80 stenosis in the main branch had significant relation with SBC OR: 5.91; 95% CI (1.28-27.3); p=0.023. SBC had no statistically significant relation with age, sex, length of the lesion and ejection fraction. Conclusion: In angioplasty of bifurcation lesions, the presence of more than 80% stenosis of main branch increases the probability of SBC and more classifications may be unnecessary.
