Comparative StudyMetabolic characteristics of human hearts preserved for 12 hours by static storage, antegrade perfusion, or retrograde coronary sinus perfusion.
Machine perfusion of donor hearts is a promising strategy to increase the donor pool. Antegrade perfusion is effective but can lead to aortic valve incompetence and nonnutrient flow. Experience with retrograde coronary sinus perfusion of donor hearts has been limited. We tested the hypothesis that retrograde perfusion could support myocardial metabolism over an extended donor ischemic interval. ⋯ Machine perfusion by either the antegrade or the retrograde technique can support myocardial metabolism over long intervals. Machine perfusion seems promising for long-term preservation of human donor hearts.

Observational StudySingle center experience with the Sorin Bicarbon prosthesis: a 17-year clinical follow-up.
To evaluate the long-term results of aortic valve replacement (AVR) and mitral valve replacement (MVR) with the Sorin Bicarbon prosthesis (SBP). ⋯ The SBP has shown excellent results in terms of clinical improvement and freedom from valve-related complications, even up to 17 years after AVR and MVR. It therefore seems to be a safe option whenever a mechanical prosthesis is needed.

Comparative StudyNinety-day mortality after resection for lung cancer is nearly double 30-day mortality.
To evaluate 30-day and 90-day mortality after major pulmonary resection for lung cancer including the relationship to hospital volume. ⋯ Mortality at 30 and 90 days and hospital volume should be monitored by institutions performing major pulmonary resection and benchmarked against hospitals performing at least 30 resections per year.

Multicenter StudyEndovascular treatment of late coronary-subclavian steal syndrome.
Coronary-subclavian steal syndrome (CSSS) is a rare cause of myocardial ischemia subsequent to stenosis or occlusion of the subclavian artery (SA) proximal to internal thoracic artery (ITA) coronary bypass. Only single cases have been reported in published studies to date. We report a significant series of patients with late CSSS treated through an endovascular approach. ⋯ A tailored endovascular approach can be used to treat CSSS. However, the occurrence of potentially lethal complications is possible and needs prompt correction.

Observational StudyLong-term results of Freestyle stentless bioprosthesis in the aortic position: a single-center prospective cohort of 500 patients.
Stentless xenograft bioprostheses may be the future valve of choice for aortic valve replacement. The study aim was to investigate the long-term clinical outcome after aortic valve replacement with the Medtronic Freestyle bioprosthesis (Medtronic Inc, Minneapolis, Minn). ⋯ The use of the Freestyle bioprosthesis for aortic valve replacement resulted in good long-term cardiovascular survival and freedom from structural valve deterioration in this cohort regardless of age at implantation.
