Aortic valve replacement in porcelain aorta-a novel technique for endoaortic occlusion.

Aortic valve surgery invariably becomes a high-risk, challenging procedure when there is extensive calcification of the ascending aorta which precludes safe cross-clamping. Very few case reports of performing aortic valve surgery in this condition with a non-cross-clamping technique of using endoaortic occlusion have been reported. We describe and recommend a non-cross-clamping technique of using a semi-compliant polyurethane balloon catheter (CODA balloon, Cook Incorporated, Bloomington, IN) and report its successful outcome in a patient, with porcelain aorta, who underwent aortic valve replacement.

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.
