CASE: A 40-year-old woman presented to the emergency department with a comminuted fracture of the patella with separation of the bone fragments. The patient underwent an open reduction and osteosynthesis using medial and lateral 2.0-mm nonlocking plates, which subsequently led to pain in the anterior and posterior aspects of the knee. CONCLUSION: In this patient, bicolumnar nonlocking plating was unable to adequately resist the tensile forces of the extensor mechanism...

OBJECTIVES: The failure of mitral repairs can be the result of inadequate leaflet coaptation length (CL< 8 mm at the A2-P2 level). A new annuloplasty ring conceived by the authors enables post-surgical CL increase using percutaneous balloon catheter technology. We conducted preclinical studies to assess the in vivo feasibility of the procedure and the safety of the postimplant deformable mitral ring. METHODS: The new annuloplasty ring allows the percutaneous and progressive displacement of each of the 3 anatomical regions of the posterior mitral annulus towards the anterior...

Aims: Heart failure (HF) is accompanied by major neuroendocrine changes including the activation of the natriuretic peptide (NP) pathway. Using the unique model of patients undergoing implantation of the CARMAT total artificial heart and investigating regional differences in soluble neprilysin (sNEP) in patients with reduced or preserved systolic function, we studied the regulation of the NP pathway in HF. Methods and results: Venous blood samples from two patients undergoing replacement of the failing ventricles with a total artificial heart were collected before implantation and weekly thereafter until post-operative week 6...

The desire to overcome the limitations of cardiovascular metal stents is driven by the global clinical need to improve patient outcomes. The opportunity for fully polymeric stents made from materials like Poly-L-lactide Acid (PLLA) is significant. Unfortunately, this potential has not been fully realised due to pressing concerns regarding the radial strength and recoil associated with material stiffness and recoverability. In an effort to achieve effective and reliable performance, it is conceivable that a certain degree of shape memory effect (SME) could be beneficial in order to improve on high recoil associated with fully polymeric stents...

Peritoneal dissemination is a particular form of malignant progression in ovarian cancer, preceding hematogenic or lymphatic dissemination. Thus, prevention of peritoneal implantation of cancer cells is envisioned to inhibit neoplastic dissemination and therefore prolong disease remission and patient's survival. Areas covered: An extended review on the role of MUC16 (CA125) and mesothelin (MSLN), expressed in a high percentage of ovarian carcinomas, indicate that this duet is relevant for the contact between cancer cells and mesothelial cells in homotypic (cancer cell-cancer cell) and heterotypic (cancer cell-mesothelial cell) interactions...

OBJECTIVE: Hemivertebrae (HV) located at the lower lumbar or lumbosacral region often produce early trunk imbalance and long compensatory curves. Because of the biomechanical characteristics of the lumbosacral junction, the rate of instrumentation failures at the region has always been high. Our study aimed to evaluate the results of posterior HV resection with lumbosacral fixation and fusion in the treatment of congenital scoliosis and to make a preliminary analysis of the possible risk factors for instrument failures...

PURPOSE: Numerous techniques are used to prevent infection after immediate implant-based breast reconstruction. Postoperative antibiotic prophylaxis (PAP) is commonly prescribed to decrease the risk of reconstructive failure, despite conflicting evidence regarding its effectiveness. We sought to determine whether PAP decreases the risk of infection-related explantation in the setting of immediate prosthesis-based breast reconstruction. METHODS: Using Truven MarketScan databases, we identified all patients who underwent immediate implant reconstruction between 1/2010-6/2014 with at least 6 months of follow-up...

INTRODUCTION: The bidirectional Glenn operation for congenital heart disease produces anatomical constraints to conventional transvenous pacemaker implantation. An iliac approach, although not previously described in this population, is potentially a preferable alternative to a thoracotomy for epicardial pacing. METHODS AND RESULTS: A single-center retrospective review was performed for all patients that underwent transvenous pacemaker implantation following the bidirectional Glenn operation with partial biventricular repair...

Interest has recently developed in the purposeful retention of root fragments with their periodontal apparatus to support bone and soft tissue at immediate implant sites in the esthetic zone. This methodology is designed to avoid bone grafting, connective tissue grafts, and the use of membranes and may have short-term benefits in terms of tissue preservation. However, it is not completely without long-term risks. At times, implants may be unintentionally placed into edentulous sites where root fragments remain...

The problem of venous thromboembolic complications (VTECs) in patients with cardiovascular implantable electronic devices (CIEDs) is extremely important today because of an annually increasing number of surgical interventions for life-threatening arrhythmias and chronic heart failure. There are hitherto no clearly defined reliable risk factors for VTECs due to heterogeneity of the available literature data. Some sources point to elevated thrombus formation in patients with a large number of electrodes, in repeat operative interventions, in the presence of a temporary pacemaker, in implantation on the left side, silicon cover of an electrode, others refute these facts...

BACKGROUND: The latissimus dorsi flap is a popular choice for autologous breast reconstruction. To dramatically improve volume, we report our experience of using the immediately lipofilled extended latissimus dorsi (ELD) flap and show it as a valid option for autologous breast reconstruction. METHODS: Patients undergoing the procedure between December 2013 and June 2016 were included. Demographic, clinical and operative factors were analysed, together with in-hospital morbidity and duration of postoperative hospital stay...

Cardiac electrophysiology is an evolving specialty that has seen rapid advances in recent years. Concurrently, there has been much progress in the field of cardiac imaging. Electrophysiologists are increasingly requesting cross-sectional imaging in advance of many procedures. Pulmonary vein isolation and left atrial appendage (LAA) occlusion are now an established treatment options for atrial fibrillation. In patients undergoing pulmonary vein isolation, applications of computed tomography (CT) include evaluating the left atrial and pulmonary venous anatomy, excluding LAA thrombus and assessing for pulmonary vein stenosis...

BACKGROUND: Multiorgan dysfunction syndrome contributes to adverse outcomes in advanced heart failure (AdHF) patients after mechanical circulatory support (MCS) implantation and is associated with aberrant leukocyte activity. We tested the hypothesis that preoperative peripheral blood mononuclear cell (PBMC) gene expression profiles (GEP) can predict early postoperative improvement or non-improvement in patients undergoing MCS implantation. We believe this information may be useful in developing prognostic biomarkers...
