And Function

The workup of patients with aortic regurgitation is routinely based on echocardiography and includes a detailed morphologic assessment of the aortic valve with the determination of disease aetiology. The quantification of aortic regurgitation is based on an integration of qualitative and quantitative parameters. Haemodynamic consequences of aortic valve disease on left ventricular size, hypertrophy, and function, as well as potentially coexisting valve lesions, are assessed. Predictors of outcome and indications for surgery are substantially defined by echocardiographic parameters. Cardiac magnetic resonance has become an important complementary technique, both for the quantification of regurgitant severity and for the assessment of ventricular function. While the proximal parts of the ascending aorta are routinely visualized by transthoracic echocardiography, transoesophageal echocardiography (TOE) and in particular cardiac magnetic resonance (CMR) and cardiac computed tomography (CT) allow a more comprehensive assessment of the thoracic aorta.
