INTRODUCTION Coronary artery bypass surgery both conventional method (Conventional Coronary Artery Bypass surgery-CCAB) and off-pump method (Off-pump Coronary Artery Bypass Surgery-OPCAB) are frequently performed operation especially in our National Institute of Cardiovascular Disease and Hospital. So far there are several other modern techniques Abstract Introduction: Coronary artery bypass surgery both conventional method (Conventional Coronary Artery Bypass surgery-CCAB) and off-pump method (Off-pump Coronary Artery Bypass Surgery-OPCAB) are frequently performed operation especially in our National Institute of Cardiovascular Disease and Hospital. Objective: To find out the Post-operative echocardiographic changes in between two groups of CABG patients. Patients and Methods: The study was conducted in the department of Cardiovascular Surgery, National Institute of Cardiovascular Disease (NICVD), Dhaka, Bangladesh. AProspective Non-randomized clinical studyFrom January 2006 to November 2007.Study population the patients with ischemic heart disease with left main coronary artery disease who underwent off pump and on pump CABG in NICVD. Non probability sampling technique. Total Sample Size number of selected patients was sixty. Thirty patients in each group. Observation and Results: Among 60 patient the mean age group I was 51.5± 7.3 and that of group II patient was 54.7± 6 years. The mean age difference was not statistically significant (p> 0.05) in unpaired t test. Among 60 patients 52 patients were male and 8 patients were female the percentages were 83.3% and 16.7% in group I and 90.0% and 10.0% in group II respectively. Male female ratio is 6.5:1. The male female differences was not statistically significant (p>0.05) in chi square test. Summary and Conclusion: In our institution more than a decade has almost over since the start of OPCAB surgery with gradual success and integrity. . This study is the pilot study and it never studied in any place before in Bangladesh. My effort in this study was to establish the safety and effectiveness of off pump coronary artery bypass surgery in left main coronary artery disease. Keywords: CCAB, OPCAB, Risk factor, CABG patients. *Corresponding Author: Kazi Zahidul Hoque, Assistant Professor (Consultant) & Unit Chief, Pediatric Cardiac Surgery Unit 2, Dhaka Shishu (Children) Hospital & Institute of Child Health, Consultant, Metropolitan Medical Center, Dhaka, Bangladesh, E-mail:kzhoque72@yahoo.com
