Clinical Trial Summary

Conventional coronary angiography is the recommended procedure in detection of coronary stenosis in patients with idiopathic cardiomyopathy. The aim of this prospective study is to assess diagnostic accuracy of multislice spiral computed tomography coronary angiography in patients with idiopathic cardiomyopathy in sinus rhythm, compared to conventional coronary angiography.


Clinical Trial Description

The principal aim of this study is to assess the diagnostic accuracy (sensitivity, specificity, predictive values) of multislice spiral computed tomography (MSCT) coronary angiography among patients having idiopathic hypokinetic dilated cardiomyopathy in sinus rhythm, compared to conventional coronary angiography. The secondary aims are to assess the performance of MSCT in coronary sinus anatomy assessment, and in quantitative measurement of left ventricular anatomical criteria (telediastolic diameter, septal and posterior wall thickness, and ejection fraction) compared to echocardiography. Lastly, renal tolerance of MSCT will be studied. This prospective monocentric study will include 120 patients scheduled to undergo coronary angiography for etiologic diagnosis of idiopathic cardiomyopathy (defined by a left ventricle echographic ejection fraction ≤ 40 %, without anamnestic or electrocardiographic arguments in favour of coronary artery disease) in sinus rhythm. MSCT will be performed within 3 months after conventional coronary angiography, with blinded analysis. ;
