Abstract

Due to the high frequency of in-stent restenosis, repeat coronary angiography and left main percutaneous coronary intervention is recommended. But Computed Tomography Angiography is a noninvasive procedure for evaluating coronary arteries. Objectives: To assess the proportion of InStent restenosis in left main per-Cutaneous coronary intervention and to evaluate diagnostic efficacy of Computed Tomography Angiography in detecting In stent Restenosis. Methods: We assessed 263 consecutive LM PCI patients; 130 patients were chosen for this study procedure as they meet our criteria. CTA was conducted three months following the LM PCI. Results: The vast majority of patients (73.8 %) had PCI from LM to LAD and 16.2 % from LM to LCX. Only 10% of patients had bifurcation PCI, and all patients had DES (100%). The average period for ISR development was 125 months, with ISR rates of 32.2 % in the LM to LAD cohort and 38 % in the LM to LCX cohort. The median time between PCI and CTA was 194 days, with a mean basal heart rate of 69 ± 12 beats per minute. CTA exhibited a positive predictive value of 84.7%. Conclusion: CTA enables an accurate noninvasive assessment of selected patients following LM PCI. And CTA can be used as a first-line treatment instead of coronary angiography.
