Observational StudyImpact of Hospital Practice and Staffing Differences on Transesophageal Echocardiography Use in Cardiac Valve or Coronary Artery Bypass Graft Surgery.
To identify and quantify the predictors of intraoperative transesophageal echocardiography (TEE) use among the patients undergoing cardiac valve or isolated coronary artery bypass graft (CABG) surgery. ⋯ Hospital practice was the strongest predictor for TEE use overall. In isolated CABG surgery, hospitals with anesthesiologist TEE staffing were a primary predictor for TEE use.

Risk Factors and Consequences of Late-Onset Hyperlactatemia After Cardiac Surgery With Cardiopulmonary Bypass: A Single-Center Retrospective Study.
Mechanisms and consequences of late-onset hyperlactatemia after cardiac surgery remain unclear. The aim of this study was to identify risk factors and outcomes of late hyperlactatemia, defined as a lactate value ≥3 mmol/L developing in the intensive care unit (ICU) after not being elevated on admission after cardiac surgery with cardiopulmonary bypass. ⋯ The strongest risk factors associated with late-onset hyperlactatemia in the authors' population were afternoon surgery and H6 bleeding >300 mL. Poor postoperative outcomes were more frequent in patients with late hyperlactatemia, even in the absence of early hyperlactatemia or severe obvious condition.

Observational StudyMitral Annulus Geometry and Dynamic Motion Changes in Patients With Aortic Regurgitation: A Three-Dimensional Transesophageal Echocardiographic Study.
The aim of the present study was to investigate the mitral annulus (MA) geometry and dynamic motion changes in patients with aortic regurgitation (AR) before and after aortic valve replacement (AVR). Moreover, the difference in the effect of the type of prosthetic aortic valve on MA was compared. ⋯ The MA geometry and dynamic motion changed markedly in patients with AR. These spatial and dynamic changes were restored to a certain extent after surgical correction of the aortic valve. However, the effects produced by mechanical and bioprosthetic valves on MA were different.
