introduction: we report a 56-year-olds female with supraventricular arrhythmia due acute ischemic stroke without structural heart disease. case description: a patient presented with sudden onset of lethargy, right hemiplegia, and global aphasia. there was previous history of stroke 1 year ago presented with left hemiplegia that recovered completely during 10 days. there was no history of comorb...

OBJECTIVE To determine the frequency of Left Atrial thrombus in patients suffering from severe mitral stenosis with atrial fibrillation. METHODS A cross sectional descriptive type study was conducted in the Echocardiography department of the National Institute of Cardio Vascular Diseases (NICVD) Karachi from October 1, 2007 to March 17, 2008. A total of 100 consecutive adult patients with sev...

The left atrium (LA) and its appendage are common sites for the formation of thrombi in patientswithmitral stenosis and atrial fibrillation due to the stasis of blood or a poorly contracting LA. The left atrial thrombus may break into several smaller pieces forming free-floating masses, leading to catastrophic embolic events such as a stroke, systemic embolization, and total or partial obstruct...

conclusions: catheter ablation of flutter circuit will not prevent later manifestation of af in 16% of the patients undergoing catheter ablation of the typical afl. bmi was the only independent predictor of af following catheter ablation of the typical afl. objectives; to determine long-term incidence and predictors of af after catheter ablation of typical afl. material and methods: between mar...

AIMS Despite exclusion of left atrial thrombi by transoesophageal echocardiography, cardioversion-related thromboembolism has been reported in atrial fibrillation or flutter. To define a low-risk group for cardioversion without previous anticoagulation, patients were selected for immediate cardioversion if there were no thrombi, no echo spontaneous contrast and the outflow velocity of the left ...

Background: P wave dispersion (PWD) is defined as the difference between the maximum P wave duration (Pmax) and the minimum P wave duration (Pmin) in 12-leads of the surface electrocardiography. The aim of this study was to evaluate the values of PWD during atrial fibrillation (AF) after acute myocardial infarction (AMI). Methods: We prospectively evaluated atrial rhythms of 350 patients (251 m...

Atrial fibrillation is a widespread disease and highly relevant as it carries an extended risk for ischaemic stroke. Surgical closure of the left atrial appendage is routinely performed during open heart surgery in patients with atrial fibrillation with the aim of thromboembolic protection. In this report we present a successful percutaneous closure of a left atrial appendage, which showed clin...

Atrial fibrillation is the most comon arrhythmia in worldwide. Stroke risk in AF is 5-fold higher than sinus rhythm. The left atrial appendage is the most important source of atrial emboli. The standard surgical “cut-and-sew” Cox-maze III procedure is the golden choice for surgical treatment of any type of atrial fibrillation, with success rate higher than 90%. A full bi-atrial lesion pattern m...

OBJECTIVE To evaluate the acute effects of atrial pacing at different pacing sites on mechanical stunning after cardioversion of atrial fibrillation (AF). SETTING Tertiary referral centre. PATIENTS 20 patients with persistent AF were studied. INTERVENTIONS Spontaneous echo contrast (SEC), left atrial appendage emptying velocity (LAAEV), and left atrial appendage emptying fraction (LAAEF) ...

Ischemic stroke is a common complication of atrial fibrillation (AF). Currently, oral anticoagulant drugs are the most commonly used method of stroke prevention. Left atrial appendage occlusion is thought to be the main source of thrombi in patients with AF. Percutaneous left atrial appendage is a valuable therapeutic option for selected high-risk patients with AF and contraindications for oral...
