Health Care Providers Working Cross-Culturally: Pitfalls, Pearls, and Preparation Resources for Culture Shock.

Health care providers engaging in cross-cultural work will likely experience culture shock, a psychological, behavioral, and physiologic response to new cultural environments that can significantly affect travelers. Culture shock has the potential for both negative and positive outcomes. Well-being, health, and professionalism can be negatively influenced during the peak of culture shock, but the experience may also positively promote transformative learning and professional identity formation.

Feasibility of focused cardiac ultrasound training for non-cardiologists in a resource-limited setting using a handheld ultrasound machine.

Background: Heart disease remains a leading cause of morbidity and mortality, particularly in low- and middle-income countries. Access to diagnostic modalities is limited in these settings. Limited echocardiographic studies performed by non-cardiologists can increase access, improve diagnosis and allow for earlier medical therapy.

Vendor independent myocardial strain values in children.

Background: Two-dimensional (2D) strain imaging has become an important tool in assessing subclinical myocardial dysfunction in children. However, there are no published normal values for vendor-independent strain software. The aim of this study was to estimate 2D strain values in a cohort of healthy children using Tomtec cardiac performance analysis (CPA), a vendor-independent software.

Comparison of Strain-Encoding and Feature-Tracking Derived Myocardial Deformation Assessment of Left Ventricular Function in a Pediatric and Adult Congenital Heart Disease Cohort.

Background: Cardiac magnetic resonance (CMR) strain can be assessed with feature-tracking (FT), which utilizes a post-processing algorithm to quantify myocardial deformation on routine cine images, and strain-encoding magnetic resonance imaging (SENC), which uses parallel magnetization tags combined with out-of-plane phase-encoding gradients to quantify deformation. Assessing agreement is critical to determine whether results can be translated between methods. We compared SENC to FT in the assessment of left ventricle (LV) global longitudinal strain (GLS) and global circumferential strain (GCS) in a cohort of pediatric and adult congenital heart disease (ACHD) patients.

Traumatic tricuspid regurgitation following equine related blunt chest trauma and review of the literature.

Myocardial injury following blunt chest trauma may be difficult to detect. We advocate for cardiac screening in such scenarios. Observation versus intervention should be based on symptoms and the degree of intracardiac disease.

Smartphone interfaced handheld echocardiography for focused assessment of ventricular function and structure in children: A pilot study.

Introduction: Miniaturized echocardiographic machines improve availability and portability and can be particularly useful for underserved and resource-limited settings. The goal of this study was to compare left ventricular fractional shortening (FS) and left ventricular ejection fraction (LVEF) obtained by a newer handheld echo (HHE) machine to standard transthoracic echocardiogram (TTE) in children.

Methods: Pediatric outpatients (Birth-18 years) undergoing TTE were prospectively enrolled.

Postcardiotomy ECMO Support after High-risk Operations in Adult Congenital Heart Disease.

Background: Cardiac operations in high-risk adult congenital heart disease (ACHD) patients may require mechanical circulatory support (MCS), such as extracorporeal membrane oxygenation (ECMO) or intraaortic balloon pump (IABP), to allow the cardiopulmonary system to recover.

Methods: We reviewed records for all ACHD patients who required MCS following cardiotomy at our institution from 1/2001 to 12/2013.

Results: During the study period, 2264 (mean age 39.
