Case in brief
A 43-year-old man with Marfan syndrome and a history of ascending aortic replacement presented in shock after transfer to the ICU. Despite poor acoustic quality in standard ultrasound views, transthoracic echocardiography revealed a dilated ascending aorta and a mobile intimal flap, indicating Stanford type A aortic dissection. The findings prompted urgent transfer for surgical intervention, although the clinical outcome post-transfer is unknown.
Diagnostic / clinical pearl
This case illustrates the critical role of focused cardiac ultrasound in diagnosing aortic dissection in patients with complex medical histories, particularly when conventional imaging is limited.
Why it matters
The case emphasizes the need for thorough assessment of the ascending aorta in shock patients, even those with prior aortic surgeries, to avoid delays in diagnosis and treatment.
