Evolving technology: the TRIFLO tri-leaflet mechanical valve without oral anticoagulation: a potential major innovation in valve surgery.

The aortic valve is the most frequently diseased valve and aortic stenosis (AS) is the most prevalent valvular heart disease in developed countries. The diseased native aortic valve can be replaced by either a biological or mechanical valve prosthesis. The main concerns relate to durability, the need for oral anticoagulants and the incidence of complications related to this medication.

Dismal prognosis of patients with operative indication without surgical intervention in active left-sided infective endocarditis.

Introduction: Around 25% of patients with left-sided infective endocarditis and operative indication do not undergo surgery. Baseline characteristics and outcomes are underreported. This study describes characteristics and outcomes of surgical candidates with surgical intervention or medical treatment only.

A Very Rare Cause of Dyspnea in a Child: A Hydatid Cyst From Echinococcus.

Hydatid cyst is a human parasitic disease caused by echinococcus granulosus that affects mainly the liver or the lungs but may be found in any organ, including the heart in up to 2% of the cases. Humans are infected as accidental hosts by contaminated vegetables or water and by contact with saliva from infected animals. Although cardiac echinococcosis can be fatal, it is rare and often asymptomatic in the early stage.

Twenty-five year experience with aortic valve-sparing root replacement in a single teaching center.

Objectives: Aortic valve-sparing root replacement (AVSRR) is a technically demanding procedure. In experienced centers it offers excellent short- and long-term results, making the procedure an attractive alternative for aortic root replacement especially in young patients. The aim of this study was to analyze long-term results of AVSRR using the David operation in our institution over the last 25 years.

Long-distance donor heart procurement using an innovative cold static storage system.

The global lack of donor shortage poses a major limitation for heart transplantation. New concepts with expanded donor inclusion criteria comprise extended transport distances and prolonged ischemic times with the aim of reaching a larger number of potential donors. Recent developments in cold storage solutions may allow more donor hearts with prolonged ischemic times to be use for transplantation in the future.

Aortic wrapping is life-saving in high-risk acute aortic dissection and intramural haematoma.

Aortic wrapping is a controversial repair in patients presenting with acute type A aortic dissection or intramural haematoma, but this method may be a potential alternative to medical treatment or conventional repair in patients aged >80 years and in those presenting with prohibitive co-morbidities such as stroke, circulatory collapse, full oral anticoagulation with the last generation drugs. We report on 5 high-risk and/or patients over 80 years who received external aortic wrapping with or without cardiopulmonary bypass during the last 18 months. All survived the procedure and could be extubated early postoperatively.

A case series of rare pathologies of the aorta and the aortic arch in adolescents and younger adults: Transfer of experience for an individualized approach.

Objective: While aneurysm of the aortic root, interrupted aortic arch, and aortic coarctation are the most frequent aortic diseases in adolescents and younger adults, there are a number of rare pathologies of the thoracic aorta that need individualized treatment.

Patients: We present a small case series of unusual aortic pathologies in patients presenting with a broad spectrum of symptoms: tiredness, dysphagia, dyspnea, arterial hypertension, renal failure, and claudication. (1).

Exploring How People with Expressive Aphasia Interact with and Perceive a Social Robot.

People with aphasia need high-intensive language training to significantly improve their language skills, however practical barriers arise. Socially assistive robots have been proposed as a possibility to provide additional language training. However, it is yet unknown how people with aphasia perceive interacting with a social robot, and which factors influence this interaction.

Porcelain aorta does not mean inoperability but needs special strategies.

Porcelain aorta is not an absolute contraindication for aortic valve and/or coronary bypass grafting but it requires a special strategy and individualized approach to minimize the risk of embolic complications and technical problems during opening and/or closing the aortotomy.

The impact of age and sex on in-hospital outcomes in acute type A aortic dissection surgery.

Background: Older age and female sex are thought to be risk factors for adverse outcomes after repair of acute type A aortic dissection (AAAD). The aim of this study is to analyze age- and sex-related outcomes in patients undergoing AAAD repair.

Methods: Retrospective analysis of patients undergoing emergency AAAD repair.

Acute limb ischemia after femoro-femoral extracorporeal life support implantation: A comparison of surgical, percutaneous, or combined vascular access in 402 patients.

Background: Extracorporeal life support (ECLS) is a salvage treatment for acute circulatory failure. Our high-volume tertiary centre performs more than 100 implants annually and provides ECLS-transports. With this study, we aimed to analyze the incidence and risk factors of limb ischemia depending on the vascular access.

Barlow disease: effect of mitral valve repair on ventricular arrhythmias in 82 patients in a retrospective long-term study.

Background: Patients (pt) with mitral valve prolapse (MVP) due to Barlow disase (BD) have an increased incidence of ventricular arrhythmias (VA; including ventricular tachycardias VT) and sudden cardiac death (SCD). Data on the effect of MV repair on VA are scarce.

Methods: Pre- and postoperative VA in severe mitral regurgitation (MR) with MVP due to BD undergoing surgical mitral valve repair were analyzed.

Prior intake of new oral anticoagulants adversely affects outcome following surgery for acute type A aortic dissection.

Objectives: Oral anticoagulation prior to emergency surgery is associated with an increased risk of perioperative bleeding, especially when this therapy cannot be discontinued or reversed in time. The goal of this study was to analyse the impact of different oral anticoagulants on the outcome of patients who underwent emergency surgery for acute type A aortic dissection (ATAAD).

Methods: This was a single-centre retrospective study of patients treated with oral anticoagulation at the time of surgery for ATAAD.

Do Robotic Tutors Compromise the Social-Emotional Development of Children?

Social robots are reported to hold great potential for education. However, both scholars and key stakeholders worry about children's social-emotional development being compromised. In aiming to provide new insights into the impact that social robots can have on the social-emotional development of children, the current study interviewed teachers who use social robots in their day-to-day educational practice.

An innovative cold storage system for donor heart transportation-lessons learned from the first experience in Switzerland.

Background: The current standard for donor heart preservation consists of cold organ storage in three sequential plastic bags. This technique can cause freezing injuries of the donor heart as the temperature inside the transport box is not monitored routinely. The SherpaPak™ Cardiac Transport System (CTS) (Paragonix Technologies, Cambridge, MA, USA) aims to resolve this problem by maintaining a controlled preservation temperature between 4 and 8 °C.

Iatrogenic Aortic Root Injury from Coronary Interventions: Early and Follow-up CT Imaging Findings.

Aortic injury represents a rare but potentially fatal complication of invasive coronary angiography. The authors present a series of four patients with aortic injury after invasive coronary angiography and intervention (mean age, 71 years; three women). In three patients, CT showed subintimal staining from undiluted contrast media (CM) in the aortic root with no communication to the aortic lumen.

Increasing atmospheric temperature implicates increasing risk for acute type A dissection in hypertensive patients.

Background: Acute type A aortic dissection (AAAD) is a life-threatening condition with high mortality within 24 hours. We hypothesized if there is a correlation between seasonal weather changes and the occurrence of AAAD. The aim of the present study was to identify seasonal specific weather and patient characteristics predicting the occurrence of AAAD.

Postprocedural Troponin Elevation and Mortality After Transcatheter Aortic Valve Implantation.

Background This study sought to investigate the role of postprocedural troponin elevations in mortality prediction after transcatheter aortic valve implantation and to define the threshold at which clinically relevant postprocedure myocardial injury determines mortality. Methods and Results A total of 1333 consecutive patients with transcatheter aortic valve implantation with available postprocedural high-sensitivity cardiac troponin T measurements were included in the analysis. The threshold at which postprocedure myocardial injury determines long-term mortality was identified using restricted cubic spline analysis.
