Frozen elephant trunk technique and partial remodeling for acute type A aortic dissection.
The aimed to describe the frozen elephant trunk (FET) technique and partial remodeling (PR) for acute type A aortic dissection (ATAAD), considering the long-term prognosis on the basis of our 13 years of experience. ⋯ FET and modified PR techniques could be effective for improving the long-term outcome on the distal and proximal aorta in an ATAAD.

The effectiveness of high-flow regional cerebral perfusion in Norwood stage I palliation.
Regional cerebral perfusion (RCP) has been shown to provide cerebral circulatory support during Norwood procedure. In our institution, high-flow RCP (HFRCP) from the right innominate artery has been induced to keep sufficient cerebral and somatic oxygen delivery via collateral vessels. We studied the effectiveness of HFRCP to regional cerebral and somatic tissue oxygenation in Norwood stage I palliation. ⋯ Our study revealed that HFRCP preserved sufficient cerebral and somatic tissue oxygenation during the Norwood procedure. The reduction of vascular resistance of collateral vessels increased both cerebral and somatic blood flow, resulting in improved tissue oxygen delivery.

Comparative StudyComparison of aortic root replacement in patients with Marfan syndrome.
Although the aortic-valve-sparing (AVS) reimplantation technique according to David has shown favorable durability results in mid-term and long-term studies, composite valve grafting (CVG) according to Bentall is still considered the standard procedure. ⋯ The reimplantation technique according to David was associated with excellent survival, good valve function and a low rate of re-operation, endocarditis, and stroke. There was a trend to better event-free survival for AVS patients making it the procedure of choice in MFS patients.

Re-operations on the proximal thoracic aorta: results and predictors of short- and long-term mortality in a series of 174 patients.
The aim of this study was to report results and to identify predictors of hospital and long-term mortality in patients undergoing re-operations on the proximal thoracic aorta. ⋯ Short- and long-term survival was satisfactory being excellent in patients with degenerative aneurysms and dismal in those with active endocarditis. Extensive aortic resections did not increase hospital mortality and were associated with a reduced need for aortic re-interventions. CPB time remains the most important risk factor for reduced survival in aortic surgery.
