Evaluation of end-organ protection in newborns and infants after surgery of aortic arch hypoplasia: A prospective randomized study.

Introduction: Surgical repair of aortic arch hypoplasia in children requires a "dry" surgical field with reliable end-organ protection. Perfusion strategies commonly involve deep hypothermic circulatory arrest (DHCA) and variations of the continuous perfusion techniques, such as selective antegrade cerebral perfusion (SACP) and full-flow perfusion with double aortic cannulation (DAC). We aimed to evaluate the end-organ protection in the surgery of aortic arch hypoplasia in newborns and infants using DHCA and DAC.

[Modern possibilities for transcatheter pulmonary valve replacement].

The literature review is devoted to transcatheter pulmonary valve replacement. The authors summarize the indications, clinical data and current capabilities of transcatheter pulmonary valve replacement. The authors also overviewed modern valves for transcatheter pulmonary artery replacement.

Endovascular Closure of 2 Subannular Pseudoaneurysms of the Aortic Root After Surgical Aortic Valve Replacement.

A 68-year-old woman was initially admitted with 2 subannular pseudoaneurysms of the aortic root after aortic valve replacement. The aneurysm expanded after 10 days and was treated using endovascular closure devices. ().
