ReviewStrain Imaging: An Everyday Tool for the Perioperative Echocardiographer.
Strain analysis allows for global and regional analysis of myocardial function and has been shown to be an independent predictor of outcomes after cardiac surgery. Strain imaging offers advantages over traditional EF measurements in that it is relatively angle independent, it is less dependent upon loading conditions, it is reproducible, it does not rely on geometric assumptions, and it can detect subclinical systolic dysfunction. Limitations of strain analysis include high temporal resolution requirements, a strong dependence on image quality, and inter-vendor variability. ⋯ Accordingly, further incorporation of intraoperative strain analysis with TEE could aid in prognostication for patients undergoing cardiac surgery. As perioperative strain analysis continues to advance, an understanding of these concepts is imperative for perioperative echocardiographers. It is the authors' goal to show that strain imaging can provide a reliable and objective measure that can be performed in real time to aid in decision-making and perioperative risk stratification.

ReviewMonitoring of the Sublingual Microcirculation During Cardiac Surgery: Current Knowledge and Future Directions.
Handheld vital microscopes allow for direct observation of the sublingual microcirculatory perfusion during cardiac surgery. Through the use of handheld vital microscopes, it has been shown that cardiac surgery with cardiopulmonary bypass is associated with reduced and heterogenous microcirculatory perfusion. Microcirculatory impairment can result in inadequate tissue perfusion, leading to perioperative complications and poor outcome. ⋯ The implementation of microcirculatory variables into personalized treatment concepts has the potential to improve hemodynamic management during cardiac surgery and thereby improve patient outcomes. Therefore, specific treatment strategies need to be developed to prevent or treat alterations of the microcirculatory perfusion. In the future, the use of handheld vital microscopes for microcirculatory monitoring may help to improve hemodynamic management and outcomes for patients undergoing cardiac surgical procedures.

Assessment of Resident Performance During the Cardiac Anesthesia Rotation: Application of the House Officer Clinical Assessment in Cardiac Anesthesiology.
The assessment of clinical skills was created that evaluates House Officer performance within 13 clinical domains during the Cardiac Anesthesiology rotation to provide an assessment and evaluation process for residents while performing a cardiac anesthetic. ⋯ The House Officer Clinical Assessment in Cardiac Anesthesiology allows for a more objective assessment of performance for specific portions of the case and allows for improved feedback on performance. Aspects of the evaluation tool and where residents correlate with the Anesthesiology Milestones for residency are discussed, as well as the ability to determine sufficient proficiency with knowledge and skills over the use of subjective rank to determine competency.

Observational StudyRescue Echocardiography/Ultrasonography in the Management of Combined Cardiac Surgical and Medical Patients in a Cardiac Intensive Care Unit.
Rescue point-of-care ultrasound (r-POCUS) in critical care medicine has revolutionized the management of critically ill patients with hemodynamic instability. However, clinical studies on its use among high-risk cardiac patients still are limited. The authors aimed to assess the utility of r-POCUS for managing high-risk cardiac patients in a mixed cardiac-surgical and cardiac-medical intensive care unit (ICU) in a quaternary care hospital by reviewing the indications and findings of r-POCUS and subsequent effect on patient management. ⋯ In this retrospective study, r-POCUS performed by attending intensivists resulted in diverse findings and was associated with rapid changes in clinical management of patients in a high-acuity, mixed cardiac-surgical and cardiac-medical ICU.
