Panel A: transthoracic echocardiography, modified four chamber subscostal view showing the dissecting tract through right ventricular free wall forming an intramural neo-cavity (asterisk), the arrow indicates the re-entry point of dissecting tract into right ventricle chamber. Panel B: transthoracic echocardiography, modified short axis subcostal view showing rupture of the inferobasal septum at the point that originates the right ventricular wall dissection (arrow), asterisk indicates the dissected neo-cavity. Panel C: postoperative transesophageal echocardiography, transgastric short axis view showing thickened basal segments of the right ventricle and inferobasal septum without visible dissecting tract (black arrow), note increased echoreflectivity at this site. Acoustic shadow caused by prosthetic patch has been indicated (asterisk). Abbreviations: LV, left ventricle, RA, right atrium, RV, right ventricle.
