Untersuchungstechniken und Stellenwert der CT bei der Diagnostik von Herzklappenerkrankungen

Abstract

Cardiac computed tomography (CT) is the first-line modality for coronary assessment. In addition valvular morphology and function can be evaluated. The method of choice for the evaluation of cardiac valves is echocardiography, followed by magnetic resonance imaging. Recent technical improvements and advances in temporal resolution allow a detailed anatomical and functional evaluation of the cardiac valves. Cardiac CT provides an excellent image quality of the aortic and mitral valve thus enabling an evaluation of the morphology. In addition, cardiac CT allows an assessment of aortic valve function with respect to the grading of stenosis and regurgitation. Cardiac CT is not considered the first-line modality for the evaluation of cardiac valves; however, beyond coronary assessment CT provides important information on the morphology and function of cardiac valves. Cardiac CT can be a useful imaging alternative for patients in whom other more commonly used methods, such as echocardiography and magnetic resonance imaging fail to provide the necessary information.
