Use Of Social Media As A Virtual Community And Support Group By Left Ventricular Assist Device (Lvad) Patients, Bryan Boling, Amanda Hart, Chizimuzo T.C. Okoli, Tamra Halcomb, Peggy El-Mallakh
The VAD Journal
Abstract
Background
Left ventricular assist device (LVAD) patients may benefit from participating in a social support group; however, several factors may limit the availability of these communities. Alternatively, online social support communities may be more accessible for LVAD patients. No studies have examined patterns and reasons for health-related social media use among people with LVADs
Methods
An online survey of patients actively participating in LVAD social media groups was conducted using both multiple choice and open-ended questions.
Results
Thirty-nine participants (65% male) completed the survey. Participants’ reasons for weekly engagement in online communities were to seek (69.2%) and offer (66.7%) …

BACKGROUND: Obesity is a risk factor for cardiovascular disease. There is evidence of impaired left ventricular (LV) function associated with obesity, which may relate to cardiovascular mortality, but some studies have reported no dysfunction. Ventricular function data are generally acquired under resting conditions, which could mask subtle differences and potentially contribute to these contradictory findings. Furthermore, abnormal ventricular mechanics (strains, strain rates, and torsion) may manifest prior to global changes in cardiac function (i.e., ejection fraction) and may therefore represent more sensitive markers of cardiovascular disease. This study evaluated LV mechanics under both resting and stress conditions with the hypothesis …

The VAD Journal
A 61-year-old woman who underwent HeartMate II left ventricular assist device placement for non-ischemic cardiomyopathy developed elevated lactate dehydrogenase within two weeks after implantation. After eight months of observation and several hospital admissions during which there was no evidence of pump thrombosis, she presented with clinically manifest hemolysis. During pump exchange there was notable pannus formation on the inflow cannula of the left ventricular assist device. The pannus around the inflow likely existed for several months, limiting the flow and creating a low-grade hemolysis and this low flow state stimulated thrombus formation triggering gross hemolysis. Thoratec analysis of the pump …

Renal dysfunction in the setting of heart failure is a common medical problem. This dysfunction can range from reversible ischemic changes to renal failure requiring renal replacement therapy. Patients who are candidates for mechanical circulatory support with left ventricular assistant device (LVAD) pose unique challenge with respect to receiving dialysis. We present a 47 year old patient who required renal replacement therapy peri-implantation of LVAD for management of acute on chronic kidney disease, and was discharged for chronic hemodialysis in an outpatient setting. In this report we highlight the challenges of managing volume overload in patients with impaired renal function …
Type Ii Endoleak Following Endovascular Repair Of Infrarenal Abdominal Aortic Aneurysm: Innovative Transgraft Approach To Contemporary Management, M. Fuad Jan, Mark W. Mewissen
Type Ii Endoleak Following Endovascular Repair Of Infrarenal Abdominal Aortic Aneurysm: Innovative Transgraft Approach To Contemporary Management, M. Fuad Jan, Mark W. Mewissen
Journal of Patient-Centered Research and Reviews
Elective endovascular aneurysm repair (EVAR) is the first-line therapeutic option for patients with infrarenal abdominal aortic aneurysm. However, endoleaks –– persistent blood flow outside the lumen of the stent graft (or endograft) but within the aneurysm sac or adjacent vascular segment being treated by the graft –– continue to be a persistent problem in the post-EVAR setting. The type II endoleak is the most common of these and can be a demanding challenge to address by standard endovascular techniques. Currently, two prominent endovascular techniques exist for the management of type II endoleaks: direct translumbar embolization and transarterial embolization. Both of …

Hepatic artery stenosis (HAS) remains a rare but serious complication after liver transplantation. While invasive surgical techniques were needed for HAS treatment in the past, recently endovascular techniques, including hepatic artery stenting, have been proven to be a safe and effective treatment. The present work focused on a review of the recent literature regarding HAS as well as recent cases demonstrating the various presentations of HAS and the variety of approaches to endovascular intervention. Our single-center experience has shown endovascular treatment of HAS to be safe and effective, including the two specific cases discussed here. While further research is needed, …

Journal of Patient-Centered Research and Reviews
Novel oral anticoagulants (NOACs) are becoming popular management options for stroke prophylaxis in nonvalvular atrial fibrillation as well as deep vein thrombosis and pulmonary embolism treatment and prophylaxis. NOACs have similar efficacy to warfarin along with noninferior safety profiles. Patient comorbidities, size, renal and hepatic function, and concomitant drug regimen play a role in which NOAC a physician may choose.

Purpose
Previous studies comparing percutaneous coronary intervention (PCI) with coronary artery bypass graft surgery (CABG) in patients with unprotected left main or three-vessel coronary artery disease (LM-3VD) have excluded patients at high surgical risk. We compared clinical outcomes after PCI with drug-eluting stents to CABG in high surgical risk patients with LM-3VD.
Methods
Patients with symptomatic LM-3VD who had Society of Thoracic Surgeons (STS)-predicted operative mortality >5% and were undergoing either PCI with drug-eluting stents or CABG at a tertiary care center from January 2009 to December 2010 were enrolled in this nonrandomized prospective study.
Results
Mean STS score was …

Acute Myocardial Infarction And Myocardial Ischemia-Reperfusion Injury: A Comparison, Satwat Hashmi, Suhail Al-Salam
Department of Biological & Biomedical Sciences
Myocardial infarction (MI) denotes the death of cardiac myocytes due to extended ischemia. Myocardial reperfusion is the restoration of coronary blood flow after a period of coronary occlusion. Reperfusion has the potential to salvage ischemic myocardium but paradoxically can cause injury, a phenomenon called as 'reperfusion injury' (IR). Standard histologic, immunohistochemical and Elisa techniques were used to study the histopathologic, oxidative, apoptotic and inflammatory changes in MI and IR. The IL-6 levels in the LV of the MI group were significantly raised as compared to the IR group (P=0.0008). Plasma IL-6 was also significantly increased in the MI group as …

The World Health Organization has established recommendations for blood pressure measurement devices for use in low-resource venues, setting the triple A expectations of Accuracy, Affordability, and Availability. Because of issues related to training and assessment of proficiency, the pendulum has swung away from manual blood pressure devices and auscultatory techniques towards automatic oscillometric devices. As a result of power challenges in the developing world, there has also been a push towards semiautomatic devices that are not dependent on external power sources or batteries. Beyond solar solutions, disruptive technology related to solid-state vibrational energy harvesting may be the next iterative solution …

Successful Use Of Therapeutic Hypothermia In A Pregnant Patient, Kevin N Oguayo, Ola O Oyetayo, David Stewart, Steven M Costa, Richard O Jones
The Texas Heart Institute Journal
Out-of-hospital cardiac arrest is a leading cause of death in the United States. Pregnant women are not immune to cardiac arrest, and the treatment of such patients can be difficult. Pregnancy is a relative contraindication to the use of therapeutic hypothermia after cardiac arrest.
A 20-year-old woman who was 18 weeks pregnant had an out-of-hospital cardiac arrest. Upon her arrival at the emergency department, she was resuscitated and her circulation returned spontaneously, but her score on the Glasgow Coma Scale was 3. After adequate family discussion of the risks and benefits of therapeutic hypothermia, a decision was made to initiate …

The radiofrequency maze procedure achieves sinus rhythm in 45%–95% of patients treated for atrial fibrillation. This retrospective study evaluates mid-term results of the radiofrequency maze—performed concomitant to elective cardiac surgery—to determine sinus-rhythm predictive factors, and describes the evolution of patients' echocardiographic variables.
From 2003 through 2011, 247 patients (mean age, 64 ± 9.5 yr) with structural heart disease (79.3% mitral disease) and atrial fibrillation underwent a concomitant radiofrequency modified maze procedure. Patients were monitored by 24-hour Holter at 3, 6, 12, and 24 months, then annually. Eighty-four mitral-valve patients underwent regular echocardiographic follow-up. Univariate and multivariate analysis for risk factors …

Primary Prevention Of Sudden Cardiac Death In Adults With Transposition Of The Great Arteries: A Review Of Implantable Cardioverter-Defibrillator Placement, Sandeep S Sodhi, Ari M Cedars
The Texas Heart Institute Journal
Transposition of the great arteries encompasses a set of structural congenital cardiac lesions that has in common ventriculoarterial discordance. Primarily because of advances in medical and surgical care, an increasing number of children born with this anomaly are surviving into adulthood. Depending upon the subtype of lesion or the particular corrective surgery that the patient might have undergone, this group of adult congenital heart disease patients constitutes a relatively new population with unique medical sequelae. Among the more common and difficult to manage are cardiac arrhythmias and other sequelae that can lead to sudden cardiac death. To date, the question …

The Texas Heart Institute Journal
We sought to validate the hypothesis that the development of atherosclerosis can be suppressed by the interleukin-1 receptor antagonist (IL-1Ra) in murine models of atherosclerosis in vivo, noninvasively seen by means of high-resolution ultrasound biomicroscopy, and we studied changes in inflammatory markers such as IL-1 and C-reactive protein (CRP) plasma levels in these models of atherosclerosis.
We divided IL-1Ra+/−/apolipoprotein-E (apoE)−/− and IL-1Ra+/+/apoE−/− mice into 2 age groups, used as atherosclerotic models. The control groups were age-matched IL-1Ra+/+/apoE+/+ mice. Plaque thickness was measured in the ascending aorta in short-axis images by means of ultrasound and histology. Plasma levels of IL-1 and …

Percutaneous coronary intervention is established as an effective treatment for patients with ischemic heart disease; in particular, drug-eluting stent implantation is known to suppress in-stent restenosis. Diabetes mellitus is an independent risk factor for restenosis, so reducing insulin resistance is being studied as a new treatment approach. In this prospective study, we sought to clarify the factors associated with in-stent restenosis after percutaneous coronary intervention, and we evaluated the homeostasis model assessment of insulin resistance (HOMA-IR) index as a predictor of restenosis.
We enrolled 136 consecutive patients who underwent elective percutaneous coronary intervention at our hospital from February 2010 through …

Alternative splicing (AS) plays an important role in regulating mammalian heart development, but a link between misregulated splicing and congenital heart defects (CHDs) has not been shown. We reported that more than 50% of genes associated with heart development were alternatively spliced in the right ventricle (RV) of infants with tetralogy of Fallot (TOF). Moreover, there was a significant decrease in the level of 12 small cajal body-specific RNAs (scaRNAs) that direct the biochemical modification of specific nucleotides in spliceosomal RNAs. We sought to determine if scaRNA levels influence patterns of AS and heart development. We used primary cells derived …

J-Wave Syndromes: Brugada And Early Repolarization Syndromes., Charles Antzelevitch, Gan-Xin Yan
Department of Medicine Faculty Papers
A prominent J wave is encountered in a number of life-threatening cardiac arrhythmia syndromes, including the Brugada syndrome and early repolarization syndromes. Brugada syndrome and early repolarization syndromes differ with respect to the magnitude and lead location of abnormal J waves and are thought to represent a continuous spectrum of phenotypic expression termed J-wave syndromes. Despite two decades of intensive research, risk stratification and the approach to therapy of these 2 inherited cardiac arrhythmia syndromes are still undergoing rapid evolution. Our objective in this review is to provide an integrated synopsis of the clinical characteristics, risk stratifiers, and molecular, ionic, …

Health care in Sub-Saharan Africa is being challenged by a double burden of disease as lifestyle diseases common in the developed world, such as stroke and atrial fibrillation (AF), increase, while, simultaneously, health issues of the developing world in terms of communicable disease persist. The prevalence of AF is lower in Africa than in the developed world but is expected to increase significantly over the next few decades. Patients with AF in Africa tend to be younger and have a higher prevalence of rheumatic valvular heart disease than patients with AF in other regions. Permanent AF is the most prevalent …

The VAD Journal
Driveline infections and sepsis are amongst the most common causes of morbidity and mortality in a patient with a left ventricular assist device. In this case, we present a patient with a multi drug resistant pseudomonas aeruginosa driveline exit site infection. Initially, it was treated with dual antibiotics, followed by surgical debridement utilizing Dakin’s solution irrigation and standard negative pressure wound therapy. Wound healing was minimal determined by poor granulation appearance, unchanged size from surgical debridement, purulent drainage, and the wound base remained colonized with multi drug resistant pseudomonas aeruginosa. A novel treatment of VeraFlo negative pressure wound therapy in …
