Objective: To evaluate the relationship between varicose veins and heart failure, both of which cause edema of lower extremities. Materials and Methods: We enrolled 150 patients who underwent intervention for varicose veins of lower extremities between December 2012 and October 2015, and perioperative data were retrospectively investigated. Results: Of the 150 patients, 104 (69.3%) were females...
AIMS This review aims to tabulate data from all available studies of temporary cardiac pacing wires. Particular aims were to determine the best route of venous access and find ways to reduce complications. The review set out to see if specialist doctors are better at inserting wires than non-specialist doctors. In addition, a contemporary study of wire insertion has been performed to compare mo...
Percutaneous electrophysiological interventions such as atrial fibrillation and ventricular tachycardia ablation are usually monitored by fluoroscopy and electroanatomical mapping systems. Electroanatomical mapping systems lacks soft tissue contrast and adequate visualization of the target area such as right ventricular out-flow tract and left atrium. Recently, real-time 3D transoesophageal ech...
Isolation of the pulmonary veins has been used as surgical treatment for atrial fibrillation (AF) from the early 90s, as it was incorporated in the Maze procedure. With the evidence that triggers form this area can induce AF, the Maze III procedure has been adapted and modified towards a single lesion around the pulmonary veins for the treatment of paroxysmal and chronic AF in some centers. New...
INTRODUCTION AND OBJECTIVES The reported incidences of stenosis after radiofrequency ablation of pulmonary veins are highly variable. Moreover, most studies have focused on severe stenosis and have overlooked mild stenosis. Our aims were to study postablation morphological changes in the pulmonary veins and to evaluate preablation magnetic resonance imaging predictors for stenosis. METHODS Ei...
A 50-year-old man presented to his cardiologist with a 1-year history of palpitations and exertional chest pressure , dyspnea, and dizziness. His surgical and medical history was unremarkable, including no history of tobacco use, hyper-tension, or hyperlipidemia. Coronary angiography, transtho-racic and transesophageal echocardiography, and cardiac magnetic resonance imaging led to a diagnosis ...
Abstract Introduction While the coronary sinus and its left ventricular branches have been extensively described, veins of ventricle summit (LVS) much less studied. The emergence new ablation techniques for tachycardias, which make use LVS veins, has generated a renewed interest in anatomy these venous conduits. Purpose aim study was to describe detail using rotational angiography. Material met...
the prevalence of varicose veins was studied in 1742 male weavers in iran by completing a specially designed questionnaire and medical examination. to show the effect of occupation on the prevalence of the disease, similar study was conducted on a group of 1661 food- processing workers. the over- all prevalence of the disease in the weavers (26.12%) was significantly higher than the similar rat...
background central venous catheterization is done frequently in cardiac surgery and intensive care settings. faulty positioning of the catheter can cause many complications. objectives the aim of our study was to study the average depth of insertion and formulate a general guideline through the right internal jugular vein (ijv). patients and methods the right ijv was cannulated over a period of...
