We hypothesized that a diffuse interstitial myocardial fibrosis may be present in AR patients who experience early systolic LV dysfunction after aortic valve surgery. We aimed to evaluate the association between preoperative cardiac T1 mapping for detection of myocardial fibrosis and early systolic LV dysfunction after surgery for aortic regurgitation.
To assess whether cardiac T1 mapping for detection of myocardial fibrosis enables preoperative identification of patients at risk for early left ventricular dysfunction after surgery of aortic regurgitation.
