The role of pediatric maxillary expansion on nasal breathing. A systematic review and metanalysis.

Objective: A reduced transversal dimension of the maxilla leads to narrower nasal cavities, which may reduce airflow to the lungs. Maxillary expansion widens nasal floor. However, there is huge controversy regarding whether this increase does actually lead to increased airflow.

The European Registry for Patients with Mechanical Circulatory Support (EUROMACS) of the European Association for Cardio-Thoracic Surgery (EACTS): second report.

Objectives: The European Registry for Patients with Mechanical Circulatory Support (EUROMACS) was founded in Berlin, Germany. EUROMACS is supported fully by the European Association for Cardio-Thoracic Surgery (EACTS) and, since 2014, has functioned as a committee of the EACTS. The purpose of having the EUROMACS as a part of the EACTS is to accumulate clinical data related to long-term mechanical circulatory support for scientific purposes and to publish annual reports.

Post-traumatic ventricular septal defect: a rare indication for extracorporeal membrane oxygenation as a bridge to transplant.

A ventricular septal defect (VSD) is a rare complication of blunt chest trauma. This report presents the case of a 44-year-old man who developed a VSD as a result of high-energy closed chest trauma. We describe the initial surgical and medical management of the cardiac rupture.

Usefulness of Two-Dimensional Strain Parameters to Diagnose Acute Rejection after Heart Transplantation.

Background: Acute cellular rejection (ACR) is still a relevant complication after orthotopic heart transplantation. The diagnosis of ACR is based on endomyocardial biopsy (EMB). Recent advances in two-dimensional strain imaging may allow early noninvasive detection of ACR.

Characteristics of patients with survival longer than 20 years following heart transplantation.

Introduction And Objectives: The number of heart-transplant recipients exceeding 20 years of follow-up is steadily increasing. However, little is known about their functional status, comorbidities, and mortality. Identifying the predictors of prolonged survival could guide the selection of candidates for the low number of available donors.
