|Official Title:||Preoperative Assessment of Aortic Valve Stenosis and Coronary Artery Disease: Dual-source Computed Tomography Compared With Invasive Coronary Angiography and Transthoracic Echocardiography|
- Quality of cardiac imaging in computed tomography [ Time Frame: After comparison of imaging measurements ]

|Estimated Primary Completion Date:||December 2013 (Final data collection date for primary outcome measure)|
Until now invasive coronary angiography has established itself for the assessment of symptomatic aortic valve stenosis. Literature shows a good correlation between MSCT, MRI, TTE and TEE for evaluating the severity of the aortic valve stenosis.
The dual-source computed tomography (DSCT) is capable of assessing coronary arteries with a high sensitivity and specificity in term of relevant stenosis (>50%), due to its excellent spatial and temporal resolution. This study includes the assessment of patients with symptomatic valve stenosis. The severity of the aortic valve stenosis is being assessed by DSCT and TTE. Significant coronary artery stenosis and its localisation are assessed by DSCT and invasive coronary angiography. We examine the correlation between DSCT on one side and either TTE or invasive coronary angiography on the other.
