Outcomes of the Ross procedure in patients with an accompanying ascending aortic aneurysm.

Analysed in the article are the results of the Ross procedure in patients presenting with dilatation of the ascending portion of the aorta. A combination of aortic valve defects with dilatation of the ascending aorta of more than 45 mm supposes simultaneous prosthetic repair of the aortic valve and ascending aorta. The most common surgical procedure remains the Bentall-DeBono operation whose main disadvantage is associated with implantation of a mechanical prosthesis and the necessity of lifelong anticoagulant therapy.

[The study of microcirculation in walls of chambers of the heart in patients with aortic stenosis in dependence on heart failure stage].

We studied microcirculatory blood flow (MBF) by laser Doppler flowmetry (LDF) in 52 patients with stage III-IV aortic stenosis (AS) and class II-IV chronic heart failure (CHF). MBF was assessed in walls of right and left cardiac chambers before and after correction of the defect. Aim of this study was to assess functional state of MBF in walls of different chambers of the heart before and after defect correction in patients with AS at various stages of CHF.
