Patients with aortic stenosis waiting for aortic valve repair were investigated with echocardiography preoperatively, and a myocardial biospy was taken during the operation. The investigators aim to perform a retrospective analysis of these data, to look for correlations between biopsy-verified myocardial fibrosis and echocardiography parameters. The patients also had cardiac magnetic resonance imaging performed, for a non-invasive quantification of myocardial fibrosis.

Echocardiography parameters of systolic and diastolic function
Timeframe: Time between echocardiography exam and endomyocardial biopsy was kept as short as possible, and not more than one month apart. If no cardiac event had happened in between, echocardiography and biopsy could be regarded as being taken at the same time.
