INTRODUCTION: Recent studies suggest the administration of 100% oxygen to hyperoxic levels following return-of-spontaneous-circulation (ROSC) post-cardiac arrest may be harmful. However, the feasibility and safety of oxygen titration in the prehospital setting is unknown. We conducted a multi-centre, phase-2 study testing whether prehospital titration of oxygen results in an equivalent number of patients arriving at hospital with oxygen saturations SpO2 ≥ 94%. METHODS: We enrolled unconscious adults with: sustained ROSC; initial shockable rhythm; an advanced airway; and an SpO2 ≥ 95%...

Background: Randomized trials have consistently shown lower rates of acute kidney injury (AKI) with transcatheter aortic valve replacement (TAVR) compared with surgical aortic valve replacement (SAVR). Comparative rates of AKI for TAVR versus SAVR, and predictors and prognostic implications of AKI after aortic valve replacement (AVR) have not been well studied in nationally representative real-world data. Objectives: First, to compare rates of AKI and dialysis requiring AKI in TAVR versus SAVR...

OBJECTIVES: Turner syndrome (TS) and Marfan syndrome (MFS) are partially characterized by aortopathies with a risk of developing severe aortic dilation, stiffness and consequent dissection and aneurysm formation. The incidence of a bicuspid aortic valve (BAV) is also increased in TS. We investigated aortic stiffness in teenage TS and MFS patients and evaluated to what degree stiffness in TS patients is augmented by the presence of a BAV. METHODS: Fifty-seven patients with TS (n = 37) and MFS (n = 20), as well as 22 controls with similar age and size distribution underwent evaluation of thoracic aortic stiffness using phase-contrast magnetic resonance imaging...

OBJECTIVE: The mini-sternotomy approach is becoming a widespread technique for aortic valve surgery. However, its safety for aortic root replacement has yet to be established. The aim of the present study was to compare the operative outcomes of patients who underwent aortic root replacement via upper mini-sternotomy (mini-Bentall) to patients who underwent Bentall procedure via median sternotomy (full-sternotomy Bentall). METHODS: Between November 1998 and November 2016, 91 consecutive patients underwent full-sternotomy Bentall procedure and 26 patients underwent mini-Bentall procedure...

Peripheral intravenous (IV) cannulas are the quickest and most effective way of gaining venous vascular access and administering IV therapy. Closed-system peripheral IV cannulas have been shown to be safe and more reliable than open, non-valved peripheral cannulas in clinical practice. This article introduces the Smiths Medical DeltaVen closed-system peripheral IV cannula and includes three case studies describing its use in clinical practice and associated patient outcomes.

REVIEW
Talal Al-Atassi, Munir Boodhwani
Aortic valve (AV) preservation and repair is emerging as an attractive alternative to AV replacement in younger patients with aortic insufficiency (AI) and aortic root aneurysms. AV repair mitigates some of the risks associated with prosthetic valves. More centers are reporting the safety of AV preservation and repair and favorable short- and long-term outcomes. However, further work is needed to improve long-term repair durability and dissemination of knowledge and technique to make AV repair the gold standard in this patient population...

An inflammatory fibroid polyp (IFP) is a solitary rare benign neoplasm of the gastrointestinal tract, frequently located in the gastric antrum. IFPs account for about 0.1% of all gastric polyps. We report a case of a giant gastric inflammatory polyp of 2.5 cm × 7 cm that determines a gastric outlet obstruction called "ball valve syndrome" mimicking a gastrointestinal stromal tumor (GIST) and a gastric lymphoma, with an intestinal obstruction of high origin. Therefore, due to acute presentation we have decided to submit the patient to a subtotal gastrectomy...

Transcatheter aortic replacement has become the standard of care for patients with severe aortic valve stenosis. With advancement of technologies, this technique has become much safer and simpler. Both general anesthesia (GA) and monitored anesthesia care (MAC) have been provided for transcatheter aortic valve replacement (TAVR). MAC or awake transcatheter valve replacement was shown to carry similar clinical outcomes with significantly reduced length of stay. We reviewed the literature and presented our practical minimalist anesthesia approach to awake TAVR...

Objective Ventricular shunts are a mainstay of hydrocephalus treatment, but the detection of its clinical failure often relies on circumstantial evidence. A direct, non-interventional method for reliably evaluating cerebrospinal fluid (CSF) function does not exist due to the difficulty of measuring in vivo flow characteristics. The objective of this study is to apply a novel method of ultrasound monitoring to characterize the oscillation observed during pulsatile CSF flow and failure states in an in vitro and cadaveric model...

To evaluate variations of blood circulating in closed loops, hemorheological properties including blood viscosity and red blood cells (RBCs) are quantitatively measured with independent in-vitro instruments after collecting blood from a closed loop. But, most previous methods require periodic blood collections which induce several problems such as geometric differences between the fluidic channel and the in-vitro method, hemodilution, storage time, and unspecific blood flow rates. To resolve these issues, in this study, blood viscosity and RBC aggregation of blood circulating within a closed loop are measured with a microfluidic platform periodically and simultaneously...

Introduction: Aortic valve reconstructions using geometric annuloplasty rings HAART 300/200 open new era in aortic valve surgery. The HAART technology resizes, reshapes, stabilizes and simplifies aortic valve repair. The HAART aortic repair rings are designed to be implanted directly into aortic annulus (under aortic valve leaflets). Aim: We present first in Poland 4 cases of aortic valve reconstructions using geometric annuloplasty rings HAART 300. Material and methods: Two patients had type IA aortic insufficiency (due to El-Khoury classification) - they were treated by HAART 300 ring insertion and ascending aorta prosthesis implantation...

To assess the potential advantages of minimally invasive surgery using a single femoral venous drainage method versus femoral venous and superior vena cava or jugular venous drainage method during repeat tricuspid valve surgery.From January 2010 to December 2016, 50 repeat tricuspid valve procedures were performed using a minimally invasive approach without aortic cross-clamping at our institution. The arterial cannula was inserted into the femoral artery, and at the same time, the venous cannula was placed in the femoral vein in 28 patients (FV group) during cardiopulmonary bypass (CPB)...

Michelle Carr, Stephanie Curtis, Jan Marek
Congenital obstruction of the left ventricular outflow tract remains a significant problem and multilevel obstruction can often coexist. Obstruction can take several morphological forms and may involve the subvalvar, valvar or supravalvar portion of the aortic valve complex. Congenital valvar stenosis presenting in the neonatal period represents a spectrum of disorders ranging from the hypoplastic left heart syndrome to almost normal hearts. Treatment options vary dependent on the severity of the left ventricular outflow tract obstruction (LVOTO) and the variable degree of left ventricular hypoplasia as well as the associated lesions such as arch hypoplasia and coarctation...

BACKGROUND: The MANTA system is a novel vascular closure device (VCD) and its safety and efficacy were compared to the ProGlide VCD in patients undergoing transfemoral transcatheter aortic valve implantation (TAVI). METHODS: This is a retrospective study including 222 patients who underwent transfemoral TAVI at three Finnish University Hospitals. The MANTA VCD was used in 107 patients and their outcome was compared with that of 115 patients in whom the arterial access was closed with the ProGlide VCD...

Outcome data for neonates with critical pulmonary stenosis (PS) is limited. We aimed to review the outcomes after balloon pulmonary valvuloplasty (BPV) for neonates with critical PS at our institution. All neonates with critical PS who underwent BPV from 1990 to 2017 were included. A total of 44 neonates underwent BPV for critical PS. Nonright ventricular dependent coronary artery fistulas was seen in 6/44 (13.6%) patients. Tricuspid valve z-scores were -1.9 (interquartile range [IQR] -3.04, -0.48) in those with coronary artery fistulas as compared with -0...
