The paper discusses the techniques of modifying the atherosclerotic plaque in the left main coronary artery along with the results of the author’s own procedures using a scoring catheter (AngioSculpt) and a non-compliant (NC) balloon catheter.

Material and methods:
23 patients who met the inclusion criteria in the absence of exclusion criteria were enrolled in the study. 13 patients underwent coronary angioplasty using a scoring balloon catheter, and 10 patients underwent coronary angioplasty (percutaneous coronary intervention – PCI) with a NC balloon catheter.

The groups did not differ in terms of demographics and comorbidities. In the study group, a larger diameter of the LM trunk was obtained, as assessed by the IVUS technique. In the control group, the two-stent technique was used more often, however, due to the small number of participants, statistical significance was not achieved. In the control group, greater use of contrast was associated with more frequent use of the two-stent technique. Despite one MI related to procedure in the control group, the two-year mortality rate between groups was similar. Logistic regression did not reveal any of studied variable to be significantly related to 2-year mortality.

The preliminary results of our study suggest that there is no difference in early 30-day results and 2-year mortality in a randomized group of patients undergoing coronary angioplasty using a scoring balloon catheter and a non-compliant catheter. Selection of the optimal treatment strategy in LM stenosis is still a matter of research and the operator’s experience is of fundamental importance.
