![]() The unadjusted long-term survival was also comparable between the groups (p=0.09). In-hospital/30-day mortality rates were 19.0% in the AR group and 17.5% in the AA group (p=0.70). Postoperative outcomes were comparable between the groups. The study found that modestly dilated ARs (median MAD 4.6 cm ) appears to dissect at a significantly smaller diameter compared to modestly dilated AAs (median MAD 4.8 cm, p<0.01). There were slight differences in the operative characteristics among two groups, with a trend toward relatively frequent use of hypothermic circulatory arrest in the AA group and higher rate of concomitant coronary artery bypass graft and aortic root replacement in AR group. Moderate to severe aortic insufficiency was more common in the AR group vs AA group (35.3% vs 28.9%). The most common presentation was chest pain. The majority of patients were male (AR 78.1% vs AA 64.7%), and a small proportion had a known history of aortic aneurysm (AR 10.3% vs. The mean age was 58.5 ± 13.0 years in the AR group and 63.2 ± 13.3 years in the supracoronary AA group. Patients were stratified into two groups by location of the largest proximal aortic segment, AR (n=137) and supracoronary AA (n=530), at the time of the ATAD. Patients with connective tissue disorders, congenital bicuspid valve, familial thoracic aneurysm and dissection syndromes were excluded from the analysis. Of these, patients with maximal aortic diameters (MAD) < 5.5 cm at the time of ATAD were included in the final analysis (n=667). For the current study, patients presenting with ATAD from May 1996 to October 2016 (n = 4,254) were screened, of whom 1,120 had measurements available for both the aortic root (AR) and supracoronary AA. IRAD is an international registry consisting of 42 referral centers throughout North America, Europe and Asia that enrolls patients with acute aortic dissection. Ganapathi, MD, of Ohio State University Wexner Medical Center, and colleagues reported these findings from the International Registry of Acute Aortic Dissection (IRAD) database in a paper published online Monday and in the May 17 issue of the Journal of the American College of Cardiology. Patients with modest dilation in the aortic root (AR) had acute type A aortic dissections (ATAD) at a significantly smaller diameter compared to patients with modestly dilated ascending aorta (AA), according to registry data.Īsvin M.
