This form of RCM is characterised by severe endomyocardial fibrosis with a 'bridging scar' crossing the left ventricle. This endomyocardial bridging scar may be associated with left ventricular obstruction during systole. In early forms, focal left ventricular hypertrophy may be evident, which over time progresses to the formation of a 'bridging scar'. | This form of RCM is characterised by severe endomyocardial fibrosis with a 'bridging scar' crossing the left ventricle.
