atrial fibrillation is the most prevalent permanent arrhythmia. it may be associated with other cardiac pathologies which need surgical treatment. various types of surgery including the traditional cut-sew operations and operations using different energy sources are currently in use. in comparison with medical treatment, surgery is safe, effective, and has reliable results.

atrial fibrillation (af) is the most common arrhythmia after cardiothoracic surgery. af following coronary artery bypass graft (cabg) is associated with an increase in morbidity, mortality, hemodynamic instability, thromboembolic events, severity of heart failure and icu and hospital stay. corticosteroids have a variety of beneficial effects on recovery after elective surgery. this study was de...

A case of right atrial myxoma in a 5 year old male is presented. The Patient was admitted in the pediatric department with systemic manifestations. Myxoma was incidentally diagnosed.

cor triatriatum is an acyanotic congenital heart disease. we present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. the 2d transthoracic echocardiography and the doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium  through restrictive opening to the low-pressure, dista...

background: atrial fibrillation is a common arrhythmia in patients with rheumatic mitral and other valve diseases who are candidates for valve repair surgeries. conversion of rhythm to sinus has positive effects on quality of life and lower use of medications. the aim of this clinical study was to evaluate the effectiveness of the radiofrequency ablation maze iii procedure in the treatment of a...

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...
