Acute aortic dissection type A with acute coronary involvement: A novel classification

Acute Stanford type B aortic dissection occurred simultaneously with acute myocardial infarction

“…It is estimated that around 3% to 7% of AAD is concurrent with AMI [2,3], and mostly occurred in Stanford type A dissection. In type A AAD, the false lumen may extend proximally towards the coronary ostia producing various mechanisms of coronary occlusion, such as compression the proximal coronary by false lumen, ostium obstruction by intimal flap, dissection, avulsion and coronary artery spasm [4,5]. However, it cannot be explained by such mechanisms in our case which is infrequent seen in former reports.…”

Are there really differences between acute aortic dissections in Eastern and Western populations?

“…2,3 The authors found onset at an earlier age compared with the data reported by IRAD in patients with TA-AAD (50.5 vs 61.1 years). It was also an earlier onset compared with the reports from the German Registry for Acute Aortic Dissection Type A (GERAADA) 3 and other East Asia countries [4][5][6] (Table 1). At least 30% of patients with TA-AAD were aged 70 years or more, and 5% to 8% were aged less than 40 years in the reports of IRAD, 7 GERAADA, 3 and other East Asia countries 4,8 (Table 1).…”

Uncommon Findings Post Repair of Type A Aortic Dissection

“…Hirst et al reported coronary dissection as an extension of type A aortic dissection in less than 8% of cases [2]. The right coronary artery is more commonly involved [2,3]. Acute coronary involvement due to aortic dissection is not always associated with a flow limiting disease.…”

“…Acute coronary involvement due to aortic dissection is not always associated with a flow limiting disease. Patients with coronary involvement are usually much younger, have a higher aortic regurgitation rate and less commonly, have intramural hematoma [3].…”
