Mass Regression after Aortic Valve Replacement in Aortic Stenosis: A Comparison between "Appropriate" and "Inappropriate" Left Ventricular Hypertrophy

Giordano Tasca, FrancescoTrinca, Beatrice Riva, Douglas Skouse, Elisabetta Lobiati, Caterina Chiara DeCarlini and Amando Gamba
Abstract

Left ventricular (LV) hypertrophy is a form of adaptation to a chronic cardiac overload. In the setting of aortic stenosis (AS), LV hypertrophy develops to limit the increase of LV systolic wall stress. Aortic valve replacement (AVR), is expected to eliminate the LV burden, inducing regression of LV hypertrophy.

Transplant Renal Artery Stenosis Secondary to De Novo Fibromuscular Dysplasia

Gabriel A Hernandez, Abhijt Ghatak, Jorge M Diego and Eduardo De Marchena
Abstract

We present a patient who developed post kidney transplant renovascular hypertension due to Fibromuscular dysplasia, which was unseen on donor's renal artery angiography. The temporal relationship to the clinically manifested hypertension and the patient's profound weight loss makes us postulate her intra-abdominal fat redistribution led to nephroptosis of the transplanted kidney, causing stretching of the renal artery, exaggerating the Fibromuscular dysplasia and hemodynamically significant stenosis.

Ventricular Tachycardia after Use of Zuclopenthixol Decanoate (Clopixol® Depot) for the Treatment of Psychotic Illnesses: The First Case in the Literature

Emre Ozdemir Farris, Mustafa Karaca and Mehmet Serdar Bayata
Abstract

Certain drugs can induce ventricular tachycardia (VT) in a different mechanism. Most knowed mechanisms are creating new reentry, enhancing ventricular after potentials or exaggerating the slope of phase 4. These kind of arrhythmias can or can not be symptomatic, sustained or non-sustained and have variable ECG changes: Monomorphic or polymorphic ventriculer extras, bidirectional or torsades de pointes ventricular tachyarrhythmias. Zuclopenthixol decanoate blocks postsynaptic Dopamine receptor in the limbic system. It is a potent antagonist of D1 and D2 receptors.

Platypnea-Orthodeoxia Syndrome: Positional Reversal of the Interatrial Pressure Gradient Demonstrated by Atrial Septal Motion

Serio Farris and Serio M Kerala
Abstract

Platypnea-Orthodeoxia Syndrome (POS) is a rare clinical syndrome characterized by dyspnea and hypoxemia while upright that are relieved when the patient is supine. A right to left shunt in combination with several hypothesized hemodynamic or structural factors are needed to develop the syndrome. It is an important source of dyspnea in a small percentage of often-elderly patients. The exact mechanism for the positional increase in the shunt has remained elusive.

Adenosine Stress Myocardial Perfusion Scintigraphy and Echocardiography Application with Same Infusion

Zehra Pinar Koc, Necati Dagli, Tansel Ansal Balci, Ilgin Karaca, Ferat Kepenek and Tolga Cakmak
Abstract

Stress Echo was performed by an experienced cardiologist and MPS results were interpreted by an experienced nuclear medicine physician who didn't know stress Echo results according to 17 segment models. Sixteen patients underwent coronary angiography. Ischemia territory size in both the adenosine stress Echo and MPS were recorded and compared in segment and in patient basis.

Why Cardiac Resynchronization Therapy (CRT) is Usually Prescribed along with Automatic Implantable Defibrillation (AID)? Is it a Sensible Decision? Historical Perspective

Max E Valentinuzzi
Abstract

The objective of this paper tries to answer the questions posed in the title, that is, why Cardiac Resynchronization Therapy (CRT) is usually prescribed along with Automatic Implantable Defibrillation (AID)? Is it a sensible decision? For that matter.

A Case of Coronary Artery Spasm Associated with Lisdexamfetamine Use

Harmony R Reynolds and Leon H Charney
Abstract

Coronary artery spasm is a cause of myocardial infarction with non-obstructive coronary arteries (MINOCA). Coronary spasm may occur spontaneously or in response to prescribed or illicit drugs. Myocardial injury and cardiomyopathies have been reported in association with the use of stimulants in children and adults with attention deficit hyperactivity disorder (ADHD).

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.
