Transcatheter device implantation has become an attractive alternative to surgery in the closure of atrial septal defects in selected patients. However, it can lead to early and late sequelae, some of them life threatening. For example, 79 days before her admission to our emergency department with sudden-onset respiratory distress and respiratory arrest (leading to cardiac tamponade and rupture), a 22-year-old woman had undergone percutaneous closure of an atrial septal defect. We describe the damage and its treatment...

There is much interest in form-fitting, low-modulus, implantable devices or soft robots that can mimic or assist in complex biological functions such as the contraction of heart muscle. We present a soft robotic sleeve that is implanted around the heart and actively compresses and twists to act as a cardiac ventricular assist device. The sleeve does not contact blood, obviating the need for anticoagulation therapy or blood thinners, and reduces complications with current ventricular assist devices, such as clotting and infection...

The number of people with heart failure requiring implantation of a cardiac resynchronization device is increasing in Iran. Although this intervention is an effective life-saving treatment, several challenges are associated with patients' lifestyle after insertion. This study identified the challenges and coping mechanisms of Iranians with heart failure living with cardiac resynchronization therapy. A qualitative approach using conventional content analysis was adopted. Seventeen people with heart failure and three nurses were recruited between December 2014 and November 2015 from a teaching hospital and a private clinic in Rasht, Iran...

We report a case of a patient supported with a HeartWare left ventricular assist device for idiopathic cardiomyopathy who was resistance to vitamin-K antagonists three months after implantation. The patient initially started low-molecular-weight heparin therapy and then, after the onset of an ischemic stroke, switched to dabigatran etexilate (DE). The patient had progressive recovery of cardiac function for which the device was explanted. No thrombotic or bleeding events occurred during DE therapy.

AIMS: Cardiac resynchronization therapy (CRT) induces reverse cardiac remodelling in heart failure (HF), but many patients receiving CRT remain non-responders. This study assessed the role of amino-terminal-pro-B-type natriuretic peptide (NT-proBNP), mid-regional-pro-atrial natriuretic peptide (MR-proANP), and mid-regional-pro-adrenomedullin (MR-proADM) at the time of device implantation to predict favourable clinical course (CRT response and/or risk of MACE) in HF patients receiving CRT...

BACKGROUND: In terminal failing hearts ventricular assist devices (VAD) are implanted as a bridge to transplantation. Endothelin receptor (ETR) antagonists are used for treatment of secondary pulmonary hypertension in VAD patients. However, the cardiac ETR regulation in human heart failure and during VAD support is incompletely understood. METHODS: In paired left ventricular samples of 12 dilated cardiomyopathy patients we investigated the density of endothelin A (ETA) and B (ETB) receptors before VAD implantation and after device removal...

Chronic heart failure is a common and complex clinical syndrome that results from impaired cardiac relaxation or contraction. Patients with chronic heart failure may experience multiple debilitating symptoms, such as fatigue, pain, and peripheral oedema. However, breathlessness may be considered the most debilitating symptom. This is the first of two articles on chronic heart failure, and outlines the pathophysiology of the condition, its causes, assessment, and signs and symptoms. Part 2 will discuss the treatment and management of the condition, including pharmacological strategies, device implantation, lifestyle modification, cardiac rehabilitation and palliative care...

OBJECTIVE: We have previously established that paramedic exposure to out-of-hospital cardiac arrest (OHCA) is relatively rare, therefore clinical exposure cannot be relied on to maintain resuscitation competency. We aimed to identify the current practices within emergency medical services (EMS) for developing and maintaining paramedic resuscitation competency. METHODS: We developed and conducted an online cross-sectional survey of Australian and New Zealand EMS in 2015...

PURPOSE: Hyperthermia (HT), an adjuvant therapy for variable cancers, may cause physiological changes in the patients, which may lead to cardiovascular problems. Among various HT treatments, the physiological effects of deep regional HT are still unclear. We examined the physiological alterations throughout deep regional HT to improve the HT safety. MATERIALS AND METHODS: Thirty-one patients (age: 61±12 years) with cancer received HT in the thoracic or upper abdominal regions using an 8-MHz radiofrequency-capacitive-device for 50 min...

We present a new approach of integrated maximum current density (IMCD) for the noninvasive detection of myocardial infarction (MI) using magnetocardiography (MCG) data acquired from a superconducting quantum interference device (SQUID) system. In this study, we investigated the relationship of the maximum current density (MCD) in the current density map and the underlying equivalent current dipole (ECD) based on a novel method of reconstructing the ECD in the extremum circle of the magnetic field map. The performance of IMCD and the integrated ECD (IECD) approaches were also evaluated by using 61-channel MCG data from 39 healthy subjects and 102 patients with ST elevation myocardial infarction (STEMI)...

PURPOSE OF REVIEW: Obesity, a growing global health problem, contributes to the development of heart failure. However, increased BMI seems protective for those with established disease, a phenomenon known as the 'obesity paradox'. In this review, we outline the mechanism through which obesity can contribute to the development of heart failure, explore the concept of obesity paradox, and highlight the challenges that obesity presents for advanced heart failure therapy. RECENT FINDINGS: Although the mechanism underlying the obesity paradox is complex, meta-analysis shows that intentional weight loss through bariatric surgery can indeed improve cardiac structure and function...

Chronic total occlusions (CTO) are frequently found in clinical practice, yet they are still undertreated, despite the frequent presence of clinical indications for revascularization. The presence of a CTO is a frequent cause of incomplete revascularization, which has been associated with worse long-term outcomes (including mortality), compared to complete revascularization. Such low rates of attempted revascularization can be attributed to a common misconception about the lack of benefit of CTO revascularization, combined with historically lower success rates and higher complication rates of CTO percutaneous coronary intervention...

Cardiovascular disease remains the leading cause of death worldwide. Damage to the heart resulting from cardiovascular disease leads to gradual loss of function and reduced quality of life. Cardiac injury is particularly debilitating, more so than injury to any other organ given our current inability to either generate new and functional cardiac tissue or to mimic the actions of the heart using external devices. Advances in the field of stem cells and genetics have paved the way for the development of a variety of novel therapies...

BACKGROUND: Regional oximetry is increasingly used to monitor post-extraction oxygen status of the brain during surgical procedures where hemodynamic fluctuations are expected. Particularly in cardiac surgery, clinicians employ an interventional algorithm to restore baseline regional oxygen saturation (rSO2) when a patient reaches a critical desaturation threshold. Evidence suggests that monitoring cardiac surgery patients and intervening to maintain rSO2 can improve postoperative outcomes; however, evidence generated with one manufacturer's device may not be applicable to others...
