Intraoperative Transesophageal Echocardiography in Management of Acute Type I Aortic Dissection With Malperfusion: A...

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.
