Abstract
Our study included 50 stents placed in the proximal segment of the left anterior descending coronary artery regardless their diameters and strut thickness assessed by MSCT and CA to assess the accuracy of MSCT in the diagnosis of significant in stent restenosis.
Our results showed that MSCT is an accurate and reliable tool in diagnosis of in stent restenosis in stents more than 3mm in diameter with 100% sensitivity and specificity. However this accuracy drops markedly in the assessment of stents less than 3mm in diameter due to an artificial narrowing of the stent diameter caused by the blooming effect.
Although MSCT can’t be reliable in diagnosis of ISR in stents less than 3mm in diameter, it still can be used as a tool to rule out the presence of ISR in these stents with a negative predictive value almost 100%.
