Multicenter StudyImpact of Body Mass Index on Outcomes in Cardiac Surgery.
Body mass index (BMI) commonly is used in obesity classification as a surrogate measure, and obesity is associated with a cluster of risk factors for cardiovascular disease. The aim of this study was to investigate the impact of BMI on short-term outcomes after cardiac surgery. ⋯ The results of this study demonstrated that extreme obesity and underweight were significantly associated with early major adverse clinical outcomes. However, there was an "obese paradox" in short-term mortality after cardiac surgery.

ReviewHemodynamic Testing of Patient-Specific Mitral Valves Using a Pulse Duplicator: A Clinical Application of Three-Dimensional Printing.
To evaluate the feasibility of obtaining hemodynamic metrics of echocardiographically derived 3-dimensional printed mitral valve models deployed in a pulse-duplicator chamber. ⋯ This pulse duplicator shows promising applications in hemodynamic testing of patient-specific anatomy. Future modifications to the system may allow for visualization and data collection of gradients across the aortic valve.

Comparative Study Observational StudyGrading Aortic Stenosis With Mean Gradient and Aortic Valve Area: A Comparison Between Preoperative Transthoracic and Precardiopulmonary Bypass Transesophageal Echocardiography.
The authors hypothesized that average precardiopulmonary bypass (pre-CPB) transesophageal echocardiographic (TEE) mean gradient (PGm) and aortic valve area (AVA) values would be significantly different from preoperative transthoracic (TTE) values in the same patients and that these changes would affect pre-CPB TEE grading of aortic stenosis (AS). ⋯ The authors confirmed their hypothesis that pre-CPB TEE generates different PGm and AVA values compared with preoperative TTE. These differences often underestimate AS severity. Hemodynamic standardizations or adjustments of pre-CPB TEE PGm and AVA values may be necessary in anesthetized patients before assigning an AS grade using these parameters.

Review Observational StudyDemographics and Scholarly Productivity of American Board of Anesthesiology Volunteers: Results of an Internet-Based Bibliometric Analysis.
The American Board of Anesthesiology (ABA) has been responsible for certification of anesthesiologists since 1938. Selected ABA diplomates provide their expertise to write the ABA's written and oral examinations and to administer the oral examination required for primary certification. The demographics, administrative and educational duties, and scholarly productivity of ABA volunteers and their dependence on subspecialty certification, transesophageal echocardiography (TEE) credentials, and grant funding are unknown. ⋯ These results indicated that ABA volunteers are leaders in anesthesiology with established records of administrative, educational, and scholarly accomplishment.
