Observational StudyBicuspid aortic valve disease and ascending aortic aneurysm: should an aortic root replacement be mandatory?†.
The higher risk of adverse aortic events in patients with bicuspid aortic valve (BAV) disease and ascending aorta aneurysm is known, but the management of moderate aortic root dilatation in younger patients is a controversial issue. The aim of the study was to compare survival in patients with or without root replacement. ⋯ In patients with BAV disease, ascending aorta aneurysm and moderate dilatation of the root, the significat reduction of CPB and cross-clamp times, the stability of the residual root at long term and the low risk of adverse aortic events associated with SAAR compared with the Bentall procedure have led us to consider the isolated aortic valve replacement with supracoronary aorta replacement an alternative strategy to the Bentall procedure, especially in high-risk and older patients.

The effects of using a radial artery in patients already receiving bilateral internal mammary arteries during coronary bypass grafting: 30-day outcomes and 14-year survival in a propensity-matched cohort.
Recent studies have demonstrated the superiority of bilateral internal mammary arteries (BIMAs) as conduit material for coronary artery bypass grafting (CABG) surgery. However, there is limited research on the effects of other graft conduits used in patients who require additional bypasses. The goal of this study was to evaluate the impact of the radial artery (RA) when used in conjunction with the BIMAs. ⋯ Overall, there were no statistically significant differences in survival between the BIMA + SVG and BIMA + radial ± SVG groups over the 14 years. However, further analysis demonstrated that while the BIMA + radial ± SVG group had a trend towards decreased survival before 10 years, use of the RA in conjunction with BIMAs was associated with significantly increased survival in the later years. A larger cohort of patients with longer follow-up is needed to assess the outcomes of CABG using BIMA + radial ± SVG.

Post-mortem computed tomography and post-mortem computed tomography angiography following transcatheter aortic valve implantation†.
At present, transcatheter aortic valve implantation (TAVI) is widely used. As with any interventional treatment, however, TAVI may also be accompanied by complications and may result in periprocedural mortality. This study aims to evaluate such complications and causes of death after TAVI. ⋯ After TAVI, PMCT and PMCT angiography successfully demonstrated the complications leading to death. PMCT and PMCT angiography contribute to the post-mortem analysis of causes of periprocedural death.

Comparative StudyAortic arch aneurysm: short- and mid-term results comparing open arch surgery and the hybrid procedure†.
Open arch surgery for aortic arch aneurysm was historically associated with a high risk of postoperative morbi-mortality. Improved operative techniques have now lowered the incidence of these complications but in parallel, hybrid arch procedures have emerged. Nowadays, very little data are available about their mid-term results compared with open surgery. ⋯ The type I hybrid arch procedure fails to demonstrate better results compared with open surgery, regarding morbi-mortality at the short- and mid-term follow-up. Moreover, it increases the risk of reintervention. Patients treated by this technique must undergo a closer follow-up because of this risk. Larger randomized studies are needed to better define the exact indications of this therapy.

Surgical management of destructive aortic endocarditis: left ventricular outflow reconstruction with the Sorin Pericarbon Freedom stentless bioprosthesis†.
The treatment of complicated aortic endocarditis with periannular abscesses and root disarrangement is a surgical challenge, and includes left ventricular outflow tract (LVOT) reconstruction with the patch technique or homograft implantation. The results of a simplified technique to reconstruct the LVOT in destructive endocarditis of either the aortic native valve or valve prosthesis with the Sorin Pericarbon Freedom stentless valve are reported. ⋯ The Sorin Pericarbon Freedom stentless prosthesis, with the modified technique herein described, seems to be a good option in most of cases of destructive aortic valve endocarditis. It is promptly available in different sizes, easy to implant and, due to its pericardial inflow skirt, ideal for extensive reconstruction of the LVOT with good haemodynamic performance and low risk of relapse.
