The acquired parameters were as follows: percentage of stenosis, MLD, CSA and distal reference diameter. After PCI, IVUS studies were repeated and data on the CSA, residual stenosis and MLD were acquired. Additionally, stent size and length, deployment pressure and the use of additional post-dilatations were recorded. There were 35 patients with similar demographic data in the control group who underwent treatment of the same vessel segment with the same stent type. Additional data regarding acute complications (dissections, slow flow during or after the procedure, IM) were obtained from the existing database and complications after six months, such as the need for TVR, MACE and death, were also obtained.Significant differences were observed in terms of stent size and length, residual stenosis, post-dilatation and MLD in favour of the IVUS group; in addition, TVR was 36% lower in the IVUS group with no significant difference in MACE and death between the groups.After introduction of the method, IVUS-guided PCI exhibited reasonable safety and efficacy compared to conventional angiographically guided PCI at centres without prior experience.</abstract>
