Abstract:
Introduction :Intravascular ultrasound (IVUS) is an advanced technology used to guide percutaneous
coronary intervention (PCI) in patients with stable coronary artery disease (CAD).
Goal:This study aims to describe the first successful implementation of IVUS in patients with
stable CAD in Mongolia.
Materials and Methods :Patients with CAD who underwent either CAG or IVUS-guided PCI were prospectively
selected. All patients provided informed consent, which was approved by the Ethical
Committee of the Ministry of Health of Mongolia (March 17, 2023, №23/014). For patients who underwent CAG-guided PCI, stent deployment was performed under conventional
CAG guidance, while stent implantation was performed under IVUS guidance in patients
who underwent IVUS-guided PCI. Stent restenosis at 1-year follow-up was selected as
the primary endpoint. The differences between the CAG-guided PCI and IVUS-guided
PCI groups were compared using independent sample t-tests and chi-square tests. The
association between treatment strategy (CAG-guided PCI vs. IVUS-guided PCI) and all
cause restenosis (the study endpoint) was analyzed.
Results:A total of 51 patients with stable coronary artery disease (CAD) who underwent coronary
angiography CAG guided PCI and intravascular ultrasound (IVUS)-guided PCI were included
in the present study. The mean age was 63±9.44 years, with 88.2% male (n=45). In the
IVUS-guided PCI group, the minimal lumen area (mm²) was 4.46±1.1, and after stenting, the
minimal stent area was 8.59±0.5, showing a statistically significant difference (p<0.001). The
stent restenosis rate at 1-year follow-up in the CAG-guided PCI group and the IVUS-guided
PCI group were 16% and 3.84%, respectively. The restenosis rate in the IVUS-guided PCI
group was lower than in the CAG-guided PCI group.
Conclusion:Complete expansion of the stent on the coronary artery wall is effective in improving long
term outcomes of PCI, and IVUS guided coronary artery intervention has better long-term
results compared to angiography-guided PCI group (96.1% vs 84%).
