[Prediction of myocardial contractility after coronary bypass surgery according to preoperative contrast-enhanced magnetic resonance imaging and echocardiography].

Objective: To establish the criteria for reversibility of myocardial contractility in patients with coronary artery disease (CAD) after coronary artery bypass grafting considering data of cardiac magnetic resonance imaging (MRI) and echocardiography.

Material And Methods: We studied the results of coronary artery bypass grafting in 186 patients with CAD complicated by reduced left ventricular ejection fraction (<30%). All patients underwent cardiac MRI and echocardiography before surgery.

Penetrating Cardiac Injury from Crossbow Successfully Treated With Cardiac Autotransplantation.

A middle-aged male patient presented with self-inflicted penetrating cardiac injury from 2 crossbow bolts causing injury to multiple cardiac structures and surrounding great vessels. He was successfully treated with peripheral cannulation for cardiopulmonary bypass, median sternotomy, hypothermic circulatory arrest, autotransplantation of the heart, and repair of all intracardiac injuries.

WALANT-Epinephrine injection may lead to short term, reversible episodes of critical oxygen saturation in the fingertips.

Introduction: Although the WALANT technique's long-term safeness has been demonstrated in many studies, there are only few data investigating its short-term effects on tissue perfusion and oxygen levels. It was hypothesized that, temporarily, critical levels of tissue perfusion may occur.

Methods: Seventeen patients, who were scheduled for different procedures in WALANT technique, were injected with 5-7 ml of 1% Articain containing 1:200,000 epinephrine at the finger base.

Recombinant Silk Hydrogel as a Novel Dermal Filler Component: Preclinical Safety and Efficacy Studies of a New Class of Tissue Fillers.

Background: Hyaluronic acid-based tissue fillers are commonly utilized in reconstructive surgery as well as for aesthetic augmentation. A new type of recombinant silk-based tissue filler might pose a beneficial alternative for surgeons and patients.

Objectives: The aim of this study was to compare injectability, reshaping, tolerability, and postimplantation behavior of dermal filler preparations containing recombinant silk hydrogel with a commercially available hyaluronic acid filler in 2 different animal models.
