OBJECTIVES The aim of this study was to develop new models for prediction of short-term mortality risk in on-pump coronary artery bypass grafting (CABG) surgery using decision tree (DT) methods. METHODS Between September 2005 and April 2006, 948 consecutive patients underwent CABG surgery at Rajaie Heart Center. Potential risk factors were reviewed and(More)
BACKGROUND Pleurotomy during coronary artery bypass grafting (CABG) may cause post-operative events, mostly pulmonary complications. In this study, we evaluated the influence of pleurotomy during CABG on the clinical outcome following left internal mammary artery (LIMA) harvesting. METHODS Between March and August 2009, 102 patients who underwent cardiac(More)
OBJECTIVE Although the classical Cox-Maze III is the gold standard surgical therapy with a proven efficacy in the treatment of atrial fibrillation (AF), complexity of this procedure has resulted in a search for a simpler, less invasive and more cost-effective method. In this study we evaluated the results of cryosurgical ablation in the treatment of chronic(More)
We reviewed the records of 45 patients (mean age, 46.6 ± 14.9 yr; range, 21-84 yr) with a diagnosis of constrictive pericarditis who had undergone pericardiectomy from 1994 through 2006. Preoperatively, 2 of the patients (4.4%) were in New York Heart Association (NYHA) functional class I, 20 (44.4%) in class II, 22 (48.9%) in class III, and 1 (2.2%) in(More)

Mechanical valves, on the other hand, are more durable but require anticoagulation therapy and carry the elevated risk of thrombosis. The aim of this study was to investigate the long-term outcomes of mechanical(More)
