BACKGROUND: Atrial fibrillation (AF) is an arrthymia characterized by increased risk of ventricle arrthymias and thromboembolism especially ischemic stroke. Most thrombus originated in the left atrial appendage, thus left atrial occlusion (LAAO) may be an effective alternative for stroke prevention in atrial fibrillation. OBJECTIVE: To assess the effect and safety of left atrial occlusion for stroke prevention in atrial fibrillation. METHODS AND RESULTS: We searched Pub Med, CENTRAL in The Cochrane Library, Embase, CBM-Disk, CNKI for published trials, ClinicalTrials...

BACKGROUND: The chronic consumption of androgenic anabolic steroids has shown to cause atrial arrhythmias. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. The aim of this study was to evaluate repolarization dispersion measured from the 12-lead surface electrocardiogram (including Tp-e interval, Tp-e/QT ratio, and Tp-e/cQT ratio) in bodybuilders who are using anabolic androgenic steroids (AAS)...

Hypertension (HT) is a major silent disease affecting young people because of their hereditary and modern lifestyles. Target organ damages occur before overt hypertension is diagnosed. Many offspring of HT parents show early changes in their cardiovascular autonomic functions. Heart rate variability (HRV) provides a window to understand the cardiac autonomic balance. This study was designed to quantify and to compare the HRV among the normotensive young male offspring without history of parenteral hypertension & diabetic (control group, n = 25, age 20...

Marfan syndrome is an autosomal dominant heritable disorder of the connective tissue that involves primarily the skeletal, ocular, and cardiovascular systems. Turner syndrome is a genetic disorder resulting from partial or complete X chromosome monosomy. We report the anesthetic management of a case of Marfan-Turner syndrome, which is the first such case to appear in the literature to our knowledge. A 3 year old ASA III girl was scheduled to undergo minor plastic surgery. She had a short webbed neck, prognathism, micrognathia, low-set ears, and a high palate...

BACKGROUND: The incidence of sudden cardiac death in persons under age 40 is roughly 3 per 100 000 persons per year in Germany and North America. Many of these deaths are found to be due to hereditary heart diseases, often a primary structural heart disease associated with arrhythmia or else a primary arrhythmia syndrome in a structurally normal heart. Such diseases are usually of autosomal dominant inheritance, often affect otherwise healthy persons, and can generally be well treated if recognized early...

REVIEW
Susan Duncan, Martin J Brodie
Sudden unexpected death in epilepsy (SUDEP) has an incidence ranging between 0.09 and 9 per 1000 patient-years depending on the patient population and the study methodology. It is the commonest cause of death directly attributable to epilepsy, and occurs at or around the time of a seizure. The principal risk factor for SUDEP is poorly controlled generalized tonic-clonic seizures. Other risk factors include polytherapy, male sex, early age at onset of epilepsy, symptomatic etiology, and, possibly, treatment with lamotrigine...

Tei-Index is a useful echocardiographic parameter for evaluating global cardiac function. Conventionally, a value and b value, which the calculation of Tei index is based on, are measured in different cardiac cycle. Therefore, accuracy of Tei index is damaged by cycle dependent variation, especially in patients with arrhythmia. The newly established Dual Doppler modality allows a synchronous measurement of both a value and b value. This study was aimed to explore the value of Tei index measured by Dual Doppler in cardiac function estimation in patients with hypertension...

REVIEW
Sumit Sarkar, Larry Schmued
"Ecstasy" (MDMA) is a powerful hallucinogenic drug which has raised concern worldwide because of its high abuse liability. A plethora of studies have demonstrated that MDMA has the potential to induce neurotoxicity both in human and laboratory animals. Although research on MDMA has been carried out by many different laboratories, the mechanism underlying MDMA induced toxicity has not been fully elucidated. MDMA has the ability to reduce serotonin levels in terminals of axons in the cortex of rats and mice. Recently we have shown that it also has the potential to produce degenerate neurons in discrete areas of the brain such as insular and parietal cortex, thalamus, tenia tecta and bed nucleus of stria terminalis (BST)...

BACKGROUND AND HYPOTHESIS: Interatrial block (IAB: P-duration > 100 ms) is poorly recognized in hospital populations. In addition to reduced left atrial function and left atrial enlargement it predicts atrial fibrillation and other arrthymias. P-terminal force (Ptf): +/- biphasic P in lead V(1) > or = area of 1 small square on the electrocardiogram (ECG) grid also indicates left atrial abnormality, particularly left atrial enlargement. These 2 should be related. We determined the intercorrelation...

Arritmogenic right ventricular dysplasia (ARVD) is characterized by the gradual replacement of myocytes by adipose and fibrous tissue. Described in 1977, is considered a potentially lethal cause of cardiac disease poorly understood. This disorder usually involves the right ventricle and has been associated with arrthymia, heart failure, and sudden death. In this paper, we report a case of a 25-year-old patient with syncope associated with ventricular extrasystoles. A magnetic resonance imaging was performed and showed findings that support ARVD diagnose...

The Fontan procedure by means of an extracardiac conduit was initially proposed for patients presenting with anomalies of intra-atrial anatomy. We extended this technique to all patients with functional anatomic single ventricle. Between 1988 and 1998, 206 patients with complex cardiacanomalies underwent a total extracardiac cavopuolmonary connection. In 202 patients we used a conduit, in 4 patients we performed an IVC to pulmonary artery direct anastomosis. Ten patients underwent Conversion of a filing atriopulmonary Fontan procedure to a total extracardiac cavopulmonary connection...
