The Scanner in the Coronary Evaluation

Contribution of the Scanner in the Coronary Evaluation Before Valvular Replacement

Conventional coronary angiography is the recommended procedure in detection of coronary stenosis in patients with heart valve disease referred for surgery.The aim of this prospective study is to assess diagnostic accuracy of multislice spiral computed tomography coronary angiography in patients with heart valve disease referred for surgery.

The diagnostic accuracy of multislice spiral computed tomography coronary angiography in terms of sensitivity, specificity, negative and positive predictive value, the conventional coronary angiography being the gold standard.50 patients scheduled for valve surgery will be screened to conduct an additional multislice spiral computed tomography.
