PURPOSE

MDCT-CA is a novel imaging technique which has demonstrated high sensitivity and specificity to assess the presence of coronary plaques and their stenosis degree in further native vessels and in coronary by-pass. This technique strengthening our diagnostic capability, much more of myocardial scintigraphy, in revealing coronary artery disease.

METHOD AND MATERIALS

We performed MDCT-CA and conventional coronary angiography in 23 symptomatic patients (20 male, mean age 61±9 years) referred to myocardial scintigraphy examination. Conventional coronary angiography was considered as reference standard technique. Our institutional review board approved the study and all patients gave written informed consent to the procedure.

RESULTS

None patient was excluded from the study. The sensitivity, specificity, positive, and negative predictive values to detect significant coronary artery stenosis were 97.1, 95.1, 72.8, and 99.6 for MDCT-CA and 83.3, 45.5, 62.5, and 71.4 for myocardial scintigraphy, respectively.

CONCLUSION

MDCT-CA detects coronary artery stenosis better than Myocardial Scintigraphy and provides more useful diagnostic features to interventional cardiologist. Such tecnique added more anatomic details concerning calcified plaque composition, vessel diameter, and plaque distribution.

CLINICAL RELEVANCE/APPLICATION

MDCT-CA can be considered as an alternative diagnostic tool in referring symptomatic patients to conventional coronary angiography.
