Transcatheter Closure of Large Bilateral Coronary Arteriovenous Fistulae using Amplatzer Vascular Plugs

Akika Ando, Adnan Bhopalwala and Christian Spies
Abstract

A coronary arteriovenous (AV) fistula is defined as a connection between one or more coronary arteries and a cardiac chamber or great vessel, bypassing the myocardial capillary bed. For symptomatic patients, surgical intervention is the standard treatment plan. Recently, the use of transcatheter vascular plugs for the percutaneous closure of coronary AV fistulae has been reported in a few selected cases. We report the case of a 66-year-old woman with diffusely ectatic right and left coronary AV fistulae that drained into the main pulmonary artery.

Myocardial Infarction in Young versus Older Adults: An Analysis of Differences in Proportion, Risk Factors, Clinical Demographics, Angiographic Findings and in-Hospital Outcomes

Nadim Shah, Christopher Wang, Vanessa Lee, Nicholas Cox, Chiew Wong, Anne-Maree Kelly and Kean Soon
Abstract

Background: Coronary heart disease (CHD) remains a major cause of death worldwide. This study looked at the proportions, demographics, risk profile, angiographic data and in-hospital outcomes of young versus older myocardial infarction (MI) patients presenting to a community teaching hospital in Melbourne, Australia. Methods: This was a retrospective study of patients presenting prospectively, with acute MI between August 2013 and July 2014, who demonstrated coronary stenosis ≥ 50% on invasive coronary angiography in at least one epicardial coronary artery. Patients were divided into two groups by age; those who were aged 55 years or younger and those who were older.

Clinical Characterization of Pharmacologically Induced Takotsubo Syndrome: Implications for Treatment and Mechanisms

Robert W Murdock and David K Murdock
Abstract

Takotsubo Syndrome (TS) is characterized by sudden localized left ventricular (LV) dysfunction and clinical features suggesting an acute coronary syndrome. It occurs more in women and is frequently associated with emotional or physical stress. Pharmacologically induced TS (PITS) has been reported but a comprehensive characterization has not been performed. Such a characterization could provide insight into mechanisms and treatment of spontaneous TS.

Improving Atherosclerotic Cardiovascular Risk Documentation and Consequent Preventive Management in the Electronic Medical Records of Diabetic Patients

Muna aseel, Amal Al-Ali, Zelaikha Alwahedi and Mohamed Salem
Abstract

Proper documentation of Atherosclerotic Cardiovascular Disease (ASCVD) risk score and its consequent management in the newly applied electronic medical records (EMR) for diabetic's patients attending non-communicable diseases clinic in West Bay Health Center is less than ideal during Jan 2015 and Feb 2015. Poor documentation of ASCVD risk score and its consequent management will result in improper management for type 2 diabetic patients, and it will lead to undesirable consequences.

Effect of Exercise Training on Heart Sympathetic Activity and Lung Function in Mexican obese Adolescents

Benigno Linares-Segovia, Estela Nunez Lemus, Manuel Lara Marquez, Rogelio Torres Guzman, Juan Manuel Guizar-Mendoza and Norma Amador-Licona
Abstract

Introduction: The aim of this study was to evaluate the short term effect of a moderate-intensity physical activity program on heart sympathetic activity and lung function in Mexican obese adolescents. Materials and methods: We performed a longitudinal study in 38 healthy obese adolescents (24 female and 14 male). Subjects were submitted to aerobic exercise training during 90 minutes for 16 weeks, 5 days per week. Before and after the intervention program, blood pressure, anthropometric measurements, glucose, insulin, and leptin levels were evaluated, spirometry and 60 minutes electrocardiograph monitoring were performed.

Temporal Trends in Insertion of Implantable Cardioverter Defibrillators from an Australian Regional Tertiary Centre's Perspective

Harsh V Thakkar and John V Amerena
Abstract

Implantable Cardioverter Defibrillator (ICD) therapy is now standard therapy for prevention of Sudden Cardiac Death (SCD) in high-risk patients. In 2006, the Medical Services Advisory Committee (MSAC) reviewed the role of ICDs and approved them to be used for both primary and secondary prevention. This study reviews the temporal trends in indications for insertion of ICD at Geelong Cardiology Practice (GCP).

Radial-Linear Ablation in Peri-pulmonary Vein Area Prevents Inducible Atrial Fibrillation in Dogs

Xue Zhao, Yinxiang Zhu, Xiang Mei, Jiayou Zhang, Jianqiang Hu, Wenliang Lu, Xingui Guo, Li Dai, Kailei Shi and Zhenguo Liu
Abstract

A total of 22 dogs of both sexes (5-7 years old) were divided into two groups: 10 in control and 12 in ablation group. Multiple radial-linear lesions were created from PV orifice to peri-PV area in the dogs with CARTO guidance. The control animals went through the same procedure except ablation. AF inducibility was evaluated before and immediately after the procedure. All animals had inducible AF (100%) by atrial pacing combined with or without isoproterenol at baseline.

Increased Corrected QT Interval (QTc) in First Nations Women of Northern British Columbia with Systemic Lupus Erythematosus (SLE)

Fritha A Munday, Sirisha Asuri, Sarah McIntosh, Heather Jackson, Anthony Tang and Laura Arbour
Abstract

Long QT Syndrome (LQTS), a genetic predisposition to sudden cardiac death is defined by a prolonged corrected QT interval (QTc) measured on electrocardiogram (ECG). A participatory research project has been underway with the Gitxsan of Northern BC for more than ten years where the condition (LQTS1) is common, due to a founder mutation (V205M) in KCNQ1. It is effectively treated with beta blockers and avoidance of QT prolonging drugs. Some chronic conditions are also known to increase the QTc, which is an independent risk factor for sudden cardiac death.

Effects of Erythropoietin Administration on Cardiomyocytes in Landrace/Large White Pigs after Ventricular Fibrillation

Abstract

Ventricular fibrillation was induced via a pacing wire forwarded into the right ventricle in 20 female Landrace/Large-White pigs, allocated into 2 groups; the experimental group treated with a bolus dose of 5,000 U/Kg recombinant human erythropoietin and the control group which was administered saline. Cardiopulmonary resuscitation (CPR) was performed immediately after drug administration.

Spontaneous Coronary Artery Dissection: Report of 6 Cases and Literature Review

Adolfo Ferrero Guadagnoli, Miguel A Ballarino, Carlos R Leonardi, Alejandro E Contreras, Eduardo J Brenna and Jonathan Miara
Abstract

We present our recent casuistry on such an interesting issue as coronary dissections. Provide data to assist the diagnosis and treatment of this disease. Spontaneous coronary artery dissection is a non-traumatic and non-iatrogenic separation of the coronary artery walls. It is a rare cause of acute coronary syndrome, mainly affecting women with no significant cardiovascular risk factors and has varying presentations from mild chest pains to sudden cardiac death.

Left Ventricular Assist Device Placement through Left Thoracotomy in Difficult Scenarios

Lyndsay M. Mueller, Samuel H. Cho, Timothy Fritz and Asghar Khaghani
Abstract

Standard surgical approach to the implantation of a Left Ventricular Assist Device (LVAD) is through a median sternotomy. The inflow cannula is attached to the apex of the left ventricle, while the outflow graft is usually attached to the ascending aorta. We present 2 patients with prohibitive chest wall abnormalities who underwent left thoracotomy for LVAD placement, and the outflow graft alternatively attached to the descending aorta.
