Construction and Evaluation of a Realistic Low-Cost Model for Training in Chest-Tube Insertion.

Introduction: Emergency thoracostomy is applied in life-threatening situations. Simulation plays a pivotal role in training in invasive techniques used mainly in stressful situations. Currently available commercial simulation models for thoracostomy have various drawbacks.

Safety and outcomes of MitraClip implantation in functional mitral regurgitation according to degree of left ventricular dysfunction.

Introduction And Objectives: Recent randomized trials of the MitraClip system have reported controversial results in the treatment of patients with functional mitral regurgitation (FMR). The aim of the present study was to evaluate the safety and impact of MitraClip implantation on outcomes in FMR according to left ventricular (LV) status.

Methods: Patients with FMR undergoing MitraClip implantation in our center were retrospectively screened and divided into 2 groups according to LV ejection fraction (LVEF) and LV end-diastolic dimension: "very poor LV" (LVEF ≤ 20% and/or LV end-diastolic dimension ≥ 70 mm) and "poor LV" (LVEF> 20% and LV end-diastolic dimension <70 mm).
