【 摘 要 】

Coronary angiography mostly underestimates coronary artery size. Indian data is scarce on correlating quantitative angiographic coronary diameter (DQCA) to intravascular ultrasound derived coronary diameter (DIVUS). We retrospectively analyzed 10-year data (2008–2017) of patients undergoing IVUS guided left main percutaneous coronary intervention (LM-PCI). LM, ostio-proximal LAD (op-LAD), and ostio-proximal LCX (op-LCX) were analyzed in 186, 177 and 44 patients, respectively. A linear correlation was noted between D IVUS and D QCA with derived equations for LM DIVUS = 1.68 + 0.69 × DQCA, op-LAD DIVUS = 1.91 + 0.53 × DQCA, op- LCX DIVUS = 1.93 + 0.49 × DQCA. We conclude that our equations could be used for an approximate estimation of true vessel size in the absence of IVUS assessment.
