Use of Historical Surgical Times to Predict Duration of Primary Aortic Valve Replacement.
To test whether a model using a historical average of a surgeon's surgical times for primary aortic valve replacements is a more accurate predictor of actual surgical times than solely relying on a surgeon's estimate. ⋯ An uncomplicated model can assist in providing comparatively unbiased estimations of surgical time for aortic valve replacements. The model can rely on a fewer number of cases (eg, 5) and does not benefit from including more cases (eg, 20).

Multicenter Study Observational StudyAcute Kidney Injury After Cardiac Surgery by Complete KDIGO Criteria Predicts Increased Mortality.
Acute kidney injury (AKI) occurs frequently after cardiac surgery and is associated with increased mortality. The Kidney Disease: Improving Global Outcomes (KDIGO) criteria for diagnosing AKI include creatinine and urine output values. However, the value of the latter is debated. The authors aimed to evaluate the incidence of AKI after cardiac surgery and the independent association of KDIGO criteria, especially the urine output criterion, and 2.5-year mortality. ⋯ AKI diagnosed using only the urine output criterion without fulfilling the creatinine criterion and all stages of AKI were associated with long-term mortality. Preoperatively assessed mortality risk using EuroSCORE II did not predict this AKI-associated mortality.

Mitral Regurgitation After Orthotopic Lung Transplantation: Natural History and Impact on Outcomes.
Progression of mitral regurgitation (MR) after orthotopic lung transplantation (OLT) may be an underrecognized phenomenon due to the overlapping symptomatology of pulmonary and valvular disease. Literature evaluating the progression of MR after OLT currently is limited to case reports. Therefore, the hypothesis that MR progresses after OLT was tested and the association of preprocedure MR with postoperative mortality was assessed. ⋯ This study rejected the hypothesis that primary and secondary MR progresses after OLT and found that preprocedure MR was not associated with increased postoperative mortality. Despite the findings that MR does not progress in all patients, there is a subset of patients for whom MR progression is clinically significant.
