Background: We compared the location of the false lumen within the medial layer between acute intramural hematoma (AIH) and acute aortic dissection (AAD) using microscopic images of aortic specimens and examined the associations with patient characteristics, CT findings, and late outcomes.
Methods and results: Among 293 patients undergoing surgery for Stanford type A acute aortic syndrome between 2008 and 2018, 45 patients had neither an identifiable intimal tear, flow to the false lumen on preoperative CT or intimal tear by intraoperative observation (AIH group), and 98 patients with patent false lumen were enrolled (AAD group). The AIH group had a significantly thinner outer media thickness (OMT) than the AAD group.

Löffler endocarditis with hypereosinophilic syndrome is rare but can cause critical ventricular obliteration by endomyocardial fibrosis. A 52-year-old woman experienced severe right heart failure with extreme shrinkage of her right ventricle, severe tricuspid regurgitation and marked right atrial enlargement. Preoperative tests showed identical pressures in the right atrium and pulmonary artery.
