Two-dimensional echocardiography demonstrated a markedly dilated basal aorta and cardiac chambers. Thoracic computed tomography scan highlighted a pseudoaneurysm, 14.5 cm in diameter (Figure 1). Urgent surgery was planned. The operation was performed under deep hypothermic cardiopulmonary bypass (arterial and venous line in the right femoral artery and vein). A large aortic pseudoaneurysm was demonstrated arising from the dehiscence of the proximal graft anastomosis (Figure 2). The composite graft did not require replacement, and it was possible to simply re-suture the composite graft and directly close the tear. The postoperative course was uneventful with no further evidence of leak from the anastomotic sites. https://rhythm.tums.ac.ir/index.php/jthc/article/view/304 https://rhythm.tums.ac.ir/index.php/jthc/article/download/304/297
