Type I | Little dissection or infiltration of the myocardium (direct rupture) |
Type II | Multicanalicular trajectory with extensive myocardial dissection |
Type III | Rupture is protected either by a thrombus at the orifice on the ventricular side or by a pericardial adhesion (pericardial symphysis) |
Type IV | Incomplete as the trajectory does not traverse through all layers (epicardial, endocardial, or intramyocardial rupture) |
