Closure Of A Para-Valvular Aortic Leak With The Use Of 2 Amplatzer Devices And Real-Time 2− And 3-Dimensional Transesophageal Echocardiography, Kurt S Hoffmayer, Christian Zellner, Damon M Kwan, Suma Konety, Elyse Foster, Phillip Moore, Yerem Yeghiazarians

The Texas Heart Institute Journal

Paravalvular leaks are well-recognized sequelae of mechanical aortic valve implantation. Clinical manifestations include hemolysis, arrhythmias, and congestive heart failure. Frequently, patients who receive mechanical aortic valves are poor candidates for repeat valve surgery, and the reoperative mortality rate is high. Percutaneous intervention has recently become an alternative to surgery in selected patients. Herein, we describe the percutaneous closure of an aortic paravalvular leak in a 45-year-old man who had undergone 2 aortic valve replacements with mechanical valves. The patient, who was at high surgical risk due to comorbidities, underwent the implantation of 2 AMPLATZER devices with the use of real-time …

Management Of Acute Regurgitation In Left-Sided Cardiac Valves, Nahush A Mokadam, Karen K Stout, Edward D Verrier

The Texas Heart Institute Journal

The management of acute, severe cardiac valvular regurgitation requires expeditious multidisciplinary care. Although acute, severe valvular regurgitation can be a true surgical emergency, accurate diagnosis and subsequent treatment decisions require clinical acumen, appropriate imaging, and sound judgment. An accurate and timely diagnosis is essential for successful outcomes and requires appropriate expertise and a sufficiently high degree of suspicion in a variety of settings. Whereas cardiovascular collapse is the most obvious and common presentation of acute cardiac valvular regurgitation, findings may be subtle, and the clinical presentation can often be nonspecific. Consequently, other acute conditions such as sepsis, pneumonia, or nonvalvular …

Takayasu Arteritis With Coronary Aneurysms Causing Acute Myocardial Infarction In A Young Man, Sana Ouali, Slim Kacem, Fatma Ben Fradj, Rim Gribaa, Elyes Naffeti, Fahmi Remedi, Chedia Laaoueni, Essia Boughzela

The Texas Heart Institute Journal

Takayasu arteritis is an inflammatory condition that involves the large cardiac vessels, predominantly the aorta and its main branches. It typically affects young women (age, ≤40 yr), most often Asians and Latin Americans. Herein, we describe a rare manifestation of Takayasu arteritis in a 19-year-old black Tunisian man who presented with acute inferior myocardial infarction and complete atrioventricular block after occlusion from a giant aneurysm in the right coronary artery. The coronary artery disease was associated with aneurysmal dilations in the carotid, vertebral, and right renal arteries. Medical therapy improved Thrombolysis in Myocardial Infarction flow in the area of the …

Cardiac Dysfunction After Cancer Treatment, Michael S Ewer, Sandra M Swain, Daniela Cardinale, Anecita Fadol, Thomas M Suter

The Texas Heart Institute Journal

Onco-cardiology is an evolving discipline that requires the consideration of cardiotoxicity in preclinical, clinical,and therapeutic aspects of protocol development,treatment, and surveillance of patients who have undergone interventions using cardiotoxic agents. Only then can we foster new ways to maximize survival while keeping cardiac damage within acceptable limits. It is to this end that our working together has brought us to our present understanding. In the future, we may expect onco-cardiology to play an even greater role in the care of cancer patients.

Reflections On A Heart Surgery Career With Insights For Western-Trained Medical Specialists In Developing Countries, Sami S Kabbani

The Texas Heart Institute Journal

Herein, I describe my experience (spanning 40 years) in helping to develop the specialty of cardiovascular surgery in Syria. Especially in the early years, the challenges were daunting. We initially performed thoracic, vascular, and closed-heart operations while dealing with inadequate facilities, bureaucratic delays, and poorly qualified personnel. After our independent surgical center was established in early 1976, we performed 1 open-heart and 1 closed-heart procedure per day. Open-heart procedures evolved from the few and simple to the multiple and complex, and we solved difficulties as they arose. Today, our cardiac surgical center occupies an entire 6-floor building. We have 12 …

Left Atrial Ablation For Atrial Fibrillation: Creating The “Box Lesion” With A Bipolar Radiofrequency Device, Leonid Sternik, Hartzel V Schaff, David Luria, Michael Glikson, Alexander Kogan, Ateret Malachy, Maya First, Ehud Raanani

The Texas Heart Institute Journal

The maze procedure is the gold standard for the ablation of atrial fibrillation, and the “box lesion” around the pulmonary veins is the most important part of this procedure. We have created this lesion with a bipolar radiofrequency ablator, abandoning the usual use of this device (to achieve bilateral epicardial isolation of the pulmonary veins).

From March 2004 through the end of May 2010, we performed surgical ablation of atrial fibrillation in 240 patients. Of this number, 205 underwent operation by a hybrid maze technique and the remaining 35 (our study cohort) underwent the creation of a box lesion around …

Sirolimus-Eluting Stents Versus Bare-Metal Stents In Routine Clinical Use, Muhammad Munir, Jonathan Aliota, Amany Ahmed, Anwarullah Mohammed, Vei Vei Lee, Macarthur A Elayda, James M Wilson

The Texas Heart Institute Journal

Conflicting patient outcomes have been reported after the use of sirolimus-eluting stents or bare-metal stents. In this nonrandomized study, we examine the outcomes after placement of sirolimus-eluting versus bare-metal stents in an unselected population of patients who underwent percutaneous coronary revascularization.

We used THIRD-base, a longitudinal data registry of patients who underwent revascularization at our institution, to compare demographics and outcomes in patients treated with a sirolimus-eluting or bare-metal stent from January 2001 through June 2006. Outcome measures included major acute coronary and cerebral events at 30 days, target-vessel failure at 9 months and at 3 years, and stent thrombosis. …

Usefulness Of The Echocardiographic Multi-Parameter Score (Emps) In Evaluating Left Ventricular Global Heart Function, Bingyuan Zhou, Junhua Yang, Xiangjun Yang, Yongming He, Caiming Zhao, Sudan Xu, Huifeng Wang

The Texas Heart Institute Journal

In this study, we established a new index by combining several echocardiographic parameters to quantify heart failure. We selected 233 consecutive patients who underwent both echocardiographic and plasma B-type natriuretic peptide (BNP) tests within 24 hours after referral for suspected heart failure. The echocardiographic parameters included systolic function, diastolic function, left ventricular chamber remodeling, valvular lesions, systolic pulmonary arterial pressure, and regional wall-motion abnormality. Each factor was scored from 1 to 3 points according to its severity. The total point from these 6 factors is the echocardiographic multi-parameter score (EMPS).

The EMPS for 37, 51, 77, and 38 patients from …

Endovascular Repair Of Aortoesophageal And Aortobronchial Fistulae, Roberto Chiesa, Andrea Kahlberg, Yamume Tshomba, Enrico M Marone, Massimiliano M Marrocco-Trischitta, Germano Melissano

The Texas Heart Institute Journal

Aortoesophageal fistulae (AEF) and aortobronchial fistulae (ABF) are uncommon, but are in general fatal if left untreated. Conventional treatment requires surgical replacement of the thoracic aorta, along with several adjunctive procedures to repair the esophageal or tracheobronchial lesion.The mortality rates associated with open surgery reach 61% in cases of primary fistula and 78% in secondary fistula.

Thoracic endovascular aortic repair (TEVAR) has been proposed as an alternative strategy to surgical management.Although less invasive, this technique has important limitations in treating AEF and ABF, the chief of which is the high risk of graft contamination. Moreover, we still lack sufficient data …

Heterogeneity Of Left Ventricular Signal Characteristics In Response To Acute Vagal Stimulation During Ventricular Fibrillation In Dogs, Alireza Nazeri, Macarthur A Elayda, Lubomir Dragnev, Christopher M Frank, Jihong Qu, Valtino X Afonso, Abdi Rasekh, Mohammad Saeed, Jie Cheng, Mossaab Shuraih, Ali Massumi, Mehdi Razavi

The Texas Heart Institute Journal

Studies have shown that long-term vagal stimulation is protective against ventricular fibrillation; however, the effects of acute vagal stimulation during ventricular fibrillation in the normal heart have not been investigated. We examined the effects of acute vagal stimulation on ventricular fibrillation in a canine model. In 4 dogs, we induced 30-second periods of ventricular fibrillation by means of intraventricular pacing. During 2 of the 4 periods of fibrillation that we analyzed, vagal stimulation was delivered through electrodes in the caudal ends of the vagus nerves. Noncontact unipolar electrograms were recorded from 3 ventricular regions: the basal septum, apical septum, and …

The Effects Of Smoking On Pregnant Women, Meir Cohen

The Science Journal of the Lander College of Arts and Sciences

Smoking during pregnancy is accepted as the most significant avoidable risk factor for an unsuccessful pregnancy result. Smoking is linked with fetal growth restriction, and increasing evidence also suggests that smoking can cause stillbirth, preterm birth, placental abruption, and possibly sudden infant death syndrome. Smoking during pregnancy is also associated with enhanced risks of spontaneous abortions, ectopic pregnancies, and placenta previa, and it might increase risks of behavioral disorders in childhood. Studies have shown with randomized controlled trials, that smoking intervention during pregnancy has had limited success. Smoking during pregnancy continues to be an important risk factor for maternal and …

Efficient Contracting Between Foreign Investors And Host States: Evidence From Stabilization Clauses, Sam Halabi

Articles, Chapters in Books and Other Contributions to Scholarly Works

Bilateral investment treaties are agreements between sovereign states that give broad protections to investors and investments made within the jurisdiction of the other state. The prevailing view in the academy and practice is that developing countries sign bilateral investment treaties in order to reassure investors from developed states that their investments will be safe from changes in domestic law. Without these "credible commitments," investors would be deterred from making investments, depriving developing countries of foreign capital. This Article disputes that view by demonstrating that foreign investors and host states effectively contract around the risk of changes in the law. This …

Food Habits Of Harbor Seals (Phoca Vitulina Richardii) In San Francisco Bay, California, Corinne Michele Gibble

Master's Theses

The diet of harbor seals (Phoca vitulina richardii) in San Francisco Bay (SFB) in California was examined from July 2007 to July 2008 via scat analysis. Scats were collected from five major haul-out sites; 22 species of fish and one species of crustacean were identified from 422 scats. The reliance of a non-native invasive species, Yellowfin Goby (Acanthogobius flavimanus), increased in importance in the diet. Additionally, another non-native invasive fish species, Chameleon Goby (Tridentiger trigonocephalus), was found for the first time in the diet of harbor seals in SFB. Harbor seal diet was compared between seasons, locations, and years using …

In The Ruins Of Zine Pedagogy: A Narrative Study Of Teaching With Zines, Karin H. Degravelles

LSU Doctoral Dissertations

This study considers the educational significance of zines—small circulation, self-published magazines—by asking how educators who teach with zines encounter and negotiate zine pedagogy. Though the literature on zines and teaching describes many potential benefits, it also describes contradictions and failures, with some researchers even going so far as to claim that “zines do not belong in classrooms” (Guzzetti, Elliott, & Welsch, 2010, p. 71). Through this dissertation, I investigate and complicate these claims by examining the stories and perspectives of teacher/zinesters—educators who teach or have taught with zines in a classroom setting. The project is situated within theories of the …

Vive La Différence: Hollywood And France, 1914-1945, Louise G. Hilton

LSU Master's Theses

France in the early decades of the 20th century underwent a profound identity crisis. Torn between tradition and modernity, the country perceived itself to be isolated internationally and threatened politically, economically, and culturally by both internal and external forces. In French eyes, the United States moved rapidly from an ally to an adversary that not only opposed France on major foreign policy issues after World War I, but threatened the European continent both economically and culturally. For broad segments of the French elite, the United States represented modernity – and everything that was wrong with it. Contributing powerfully to anti-American …

Application Of Satellite Remote Sensing Imagery To Bridge Scour Evaluation, Xiaoyan Zhao

LSU Master's Theses

The overall goal of this research is to evaluate the applicability of the existing HEC-18 method to Louisiana bridges that are mostly situated on cohesive soils and hence to develop a more reliable design method for scour depth and scour rate prediction. Pier research in sandy soils and cohesive soils shows that the sandy soils are known to erode particle by particle, while cohesive soils usually erode in clumps rather than individual particles, which is caused by from the different bonding mechanisms between sandy soils and cohesive soils. Because the bonding in cohesive soils is so complex, the prediction of …

Since health care reform had consequences among all ethnic groups in the U.S., the news coverage of this policy issue warranted an analysis in a diverse media context. The importance of this study lies in the fact that diverse news media provide a wide range of perspectives to the public and policymakers for a better understanding of an issue at stake. In past studies, mainstream media coverage was criticized for emphasizing political conflict and gains and losses over …

Historical Études For Oboe: 17th-20th Centuries, Linwood William Zoller Iv

LSU Doctoral Dissertations

The most popular étude books for oboe in use today are Ferling’s 48 Studies (1840) and Barret’s Complete Method for Oboe (1850). Many earlier and later collections exist, but most oboists only study from these two. This monograph uses four main criteria to choose sample études from various other collections and compile them into a single étude book. These criteria include: representation of major style periods; quotations from famous excerpts for oboe or difficult passages therefrom; illustration of mechanical improvements of the time and location; and alternatives to the standard canon in established pedagogy. Thirteen études, arranged chronologically, were selected …
