Evaluation of an x-ray multilayer mirror for radiography at sub-1-keV photon energies.

An x-ray multilayer mirror on a spherical substrate designed for near-normal incidence with a photon energy of ∼738 eV (F Heα) was procured and tested. This device is intended to be used for in-flight radiography of the shell in inertial confinement fusion experiments with cryogenic targets on the OMEGA laser at the Laboratory for Laser Energetics. Experiments in self-emission on a small (∼10 J) laser system showed that the reflectivity of the mirror is high enough to record an image at laser energies as low as 0.

Fifteen-year experience with the Tirone David procedure in bicuspid aortic valve: A safe option.

Background: We evaluated short and midterm outcomes with use of aortic valve-sparing root replacement to treat bicuspid aortic valves (BAVs).

Methods: From December 2007 to January 2022, all patients with BAVs who underwent aortic root replacement using Tirone's procedure were included. This study based on department database information for retrospective and follow-up data.

Indications and perioperative outcomes of extracorporeal life support in clermont-ferrand.

Objectives: To report the epidemiological profile of the patients who underwent extracorporeal life support (ECLS) and then analyze the indications and outcomes of this procedure.

Methods: It consisted of a retrospective and descriptive study based on the database from the department of cardiovascular surgery.

Setting: University hospital clinic.

Valve-sparing aortic root replacement-midterm outcomes and quality of life.

Background: This study evaluated the midterm outcomes, the valve related events and quality of life of patients treated by valve-sparing aortic root replacement (VSRR).

Methods: From January 2003 to December 2014, 88 consecutive patients diagnosed with an aortic root aneurysm or ascending aortic aneurysms underwent VSRR surgery. The mean age was 55±14 (range 19-77) years.

Clinical outcomes of tricuspid valve repair accompanying left-sided heart disease.

Aim: To determine whether the need for additional tricuspid valve repair is an independent risk factor when surgery is required for a left-sided heart disease.

Methods: One hundred and eighty patients (68 ± 12 years, 79 males) underwent tricuspid annuoplasty. Cox proportional-hazards regression model for multivariate analysis was performed for variables found significant in univariate analyses.
