Comparative Study Observational StudyMultiple arterial grafts improve survival with coronary artery bypass graft surgery versus conventional coronary artery bypass grafting compared with percutaneous coronary interventions.
To compare long-term survival with multiple arterial coronary artery bypass grafting (CABG) (MultArt) versus percutaneous coronary intervention (PCI) in patients with multivessel disease (MVD). ⋯ In patients with MVD undergoing primary revascularization, MultArt increased survival benefit versus LITA/SV compared with PCI. Use of MultArt must increase.

Time-resolved 3-dimensional magnetic resonance phase contrast imaging (4D Flow MRI) analysis of hemodynamics in valve-sparing aortic root repair with an anatomically shaped sinus prosthesis.
The anatomically shaped sinus prosthesis (Uni-Graft W SINUS; Braun, Melsungen, Germany) used in valve-sparing aortic root replacement promises physiological hemodynamics believed to grant physiologic valve function. Using time-resolved 3-dimensional magnetic resonance phase contrast imaging (4D Flow MRI), we analyzed sinus vortex formation and transvalvular pressure gradients in patients with sinus prosthesis compared with age-matched and young healthy volunteers. ⋯ Hemodynamics closely relating to those of volunteers were confirmed in sinus prostheses, believed to grant physiological valve function. Minor differences are presumably attributed to graft compliance and temporal resolution of the acquisition. Nevertheless, long-term deterioration of valve function as it was described for straight grafts could potentially be decelerated using sinus prostheses.

Outcomes of limited proximal aortic replacement for type A aortic dissection in octogenarians.
The number of older patients with acute aortic dissection type A (AAD [A]) is increasing as the population ages. We evaluated clinical outcomes for octogenarians with AAD (A) treated surgically at our hospital. Whenever possible, we limited the replacement site of the ascending aorta to the supracoronary and hemiarch. ⋯ Our results suggest that our limited replacement protocol for emergency AAD (A) surgery has early and midterm survival benefits for octogenarians.

When a checklist is not enough: How to improve them and what else is needed.
Checklists are being introduced to enhance patient safety, but the results have been mixed. The goal of this research is to understand why time-outs and checklists are sometimes not effective in preventing surgical adverse events and to identify additional measures needed to reduce these events. ⋯ Time-outs and checklists can prevent some types of adverse events, but they need to be carefully designed. Additional interventions aimed at improving safety controls in the system design are needed to augment the use of checklists. Customization of checklists for specialized surgical procedures may reduce adverse events.
