Multicenter Study Observational StudyRemodeling root repair with an external aortic ring annuloplasty.
Although the remodeling technique provides the most dynamic valve-sparing root replacement, a dilated annulus (>25 mm) is a risk factor for failure. Aortic annuloplasty aims to reduce the annulus diameter, thus increasing coaptation height to protect the repair. The results of 177 patients with remodeling and external aortic ring annuloplasty were studied. ⋯ The standardization of remodeling root repair with calibrated expansible aortic ring annuloplasty and cusp effective height assessment improves valve repair outcomes.

A score to estimate 30-day mortality after intensive care admission after cardiac surgery.
Several risk-scoring systems have been developed to predict surgical mortality and complications in cardiac surgical patients, but none of the current systems include factors related to the intraoperative period. The purpose of this study was to develop a score that incorporates both preoperative and intraoperative factors so that it could be used for patients admitted to a cardiac surgical intensive care unit (ICU) immediately after surgery. ⋯ Preoperative and intraoperative variables can be used on admission to a cardiac surgical ICU to estimate 30-day mortality. The score could be used for risk stratification after cardiac surgery and evaluation of performance of cardiac surgical ICUs.

Comparative StudySafety of air travel in the immediate postoperative period after anatomic pulmonary resection.
The study objective was to determine whether air travel in the immediate postoperative period after anatomic pulmonary resection is associated with increased morbidity or mortality. ⋯ Overall major complications are rare in the immediate posthospital dismissal period after lung resection. Air travel during this period was not associated with any significant increase in risk of complications when compared with conventional ground transportation and seems to be a safe option for patients after chest tube removal.

Comparative StudyModerate hypothermia at warmer temperatures is safe in elective proximal and total arch surgery: Results in 665 patients.
To evaluate adverse outcomes after elective aortic arch surgery performed at higher or lower temperatures (24.0°C-28.0°C vs 20.1°C-23.9°C) within the wide range of moderate hypothermia. ⋯ In elective proximal or total arch surgery, higher temperatures (≥24.0°C-28.0°C) within the wide range of moderate hypothermia (20.1°C-28°C) are safe and, compared with colder temperatures, not associated with significantly different rates of composite and adverse outcomes.
