Why the study?
Acute type I aortic dissection can lead to devastating complications such as end-organ malperfusion, where early detection with intraoperative imaging allows efficient transition to appropriate interventions.
Intraoperative transesophageal echocardiography plays a critical role in the early detection of malperfusion during acute type I aortic dissection repair, enabling timely and life-saving interventions.

May support intraoperative imaging for malperfusion in type I dissection; hypothesis-generating and requires prospective validation.
Acute type I aortic dissection is a life-threatening emergency with potentially devastating complications, including end-organ malperfusion. Early detection of malperfusion with intraoperative imaging allows for efficient transition to appropriate interventions. We present a case of a 65-year-old male with acute type I aortic dissection who underwent emergent surgical repair of the aortic root and hemiarch followed by acutely worsening distal malperfusion. The use of intraoperative transesophageal echocardiography played a critical role in visualizing diversion of flow to the false lumen, prompting urgent vascular surgery consultation and life-saving thoracic endovascular aortic repair.
