FN1 and Myocardial fibrosis: LV strain parameters evaluated via CMR-FT can provideprognostic information for AR patients without prolonging the scanning time.Additionally, this technology is easy to implement in daily clinical practice andthus should be popularized and further studied in patients.LV-pressure and LV-volume overload in AR patients induce myocardial fibrosis(MF), characterized by increased fibronectin and glucosamine deposition andcollagen tissue changes [39].
