Mesenteric Malperfusion in Acute Aortic Dissection: Challenges and Frontiers.

Malperfusion syndrome results from end-organ ischemia in the setting of an aortic dissection. Malperfusion syndrome can affect any vascular bed with mesenteric malperfusion (MMP) being the most challenging associated with a 3- to 4-fold increase in mortality in both acute type A and B aortic dissections. The incidence MMP is between 66% and 100% in different literature.

Aortic root replacement in a patient with previous multiple surgeries for coarctation of aorta.

Coarctation of the aorta is commonly associated with congenital and acquired cardiac pathology that may require surgical intervention. Adult patients with recurrent coarctation of the aorta, with or without associated intracardiac disease pose a surgical challenge. We report a 32-year-old man who presented with ascending aortic aneurysm with severe aortic regurgitation who underwent three previous surgeries for recurrent coarctation.
