Abstract

The increased chances of in-stent restenosis have led to repeated coronary angiography and left main percutaneous coronary intervention. However, for the evaluation of coronary arteries, computed tomography angiography (CTA) is regarded as a non-invasive intervention. Objectives: To evaluate the proportion of in-stent restenosis in the left main PCI and to determine the diagnostic efficacy of CTA in detecting in-stent restenosis. Methods: We conducted this study from June 2021 to July 2022. 130 patients were chosen for the study among the 300 LM PCI patients. The CTA was conducted 3 months after the LM PCI. The data were collected and entered into the SPSS software and the descriptive analysis was conducted. Results: In our study, the majority of the patients (n=92, 70.8%) of the patients undergoing PCI from the LM to LAD, and the number of patients who went from LM to LCX was 19 patients (14.6%). Only 14.6% of the patients in our study had bifurcation PCI and all 130 (100%) patients had DES. The average period for the development of ISD was 11 months. Conclusions: CTA is quite efficient in accurately assessing the selected patients who have undergone LM PCI and CTA can be utilized as the 1" line treatment modality.
