  Purpose
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.

Condition Intervention
Valvular Disease Coronary Stenosis Procedure: Coronary scanner

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Contribution of the Scanner in the Coronary Evaluation Before Valvular Replacement

Further study details as provided by French Cardiology Society:

Primary Outcome Measures:
  • The diagnostic accuracy of coronary scanner (sensitivity, specificity, positive and negative predictive values) in the detection of the coronary stenosis higher than 50%. [ Time Frame: a month at the latest after the signature of consent ]

Secondary Outcome Measures:
  • The diagnostic accuracy of coronary scanner to detect the patients requiring or not a coronary revascularisation in more of the valvular surgery. [ Time Frame: a month at the latest after the signature of consent ]

Enrollment: 66
Study Start Date: August 2007
Study Completion Date: December 2010
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: Coronary scanner
    multislice spiral computed tomography coronary angiography
Detailed Description:
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.
