Abstract:

Objective: To determine the adequacy of stent deployment (apposition) as assessed by IVUS and its comparison with quantitative coronary angiography (QCA). Methodology: In this comparative study we analyzed the stents for adequate deployment in 100 patients who were randomly selected from the patients who underwent PCI either with bare metal or drug eluting stent comparing QCA with IVUS at our catheterization laboratory, Cardiology department. The study was conducted from August 2010 to February 2011. We used Volcano therapeutic IVUS system employing Volcano - eagle eye Gold catheter. Stents were said to be adequately deployed when there was (1) complete apposition of the stent struts over the entire length of stent. A performa was used to collect patient's details and record the IVUS analysis. SPSS version 15 was used to analyze the data. Results: A total of 100 study subjects were included in the study, mean age was 54.38 ± 9.97 years and 85% (85) were male. Diabetics were 40 %(40), 47%(47) were hypertensives, 46%(46) were dylipidemic and 36%(36) were smokers and 40%(40) had a previous myocardial infarction. It was observed that 85% (34) of the cases had their struts adequately apposed while in 15%(06) stent apposition was inadequate and needed to be further dilated .Most of the stents (52.5%) used were Endeavor. LAD was stented in 72.5 % (72) followed Circumflex12.5 %( 12), RCA 10 %( 10) while Ramus and OM1 in5 %( 6). Conclusion: In significant number of patients stents were not adequately deployed requiring re-ballooning to optimize the results as assessed by IVUS.
