[Intraoperative quality control in the coronary artery bypass grafting].

Introduction: The issue of the quality of bypass grafts, which appeared to be a key fact in the coronary artery bypass grafting (CABG), was raised with the popularization of the operations performed without the use of cardiopulmonary bypass (CPB). Among handful methods used in the past that were abundant in defects, Transit time flow measurement (TTFM) has recently stood out for its good features. The objective of the paper is: to compare main peri and postoperative results of operations with and without CPB; to establish total number of the bypass grafts revised on the basis of TTFM results in both groups of the examinees; to evaluate sensitivity, specificity, predictive rate and accuracy of TTFM with regards to the intraoperative coronary angiography (golden standard).

[Off-pump coronary bypass grafting in patient with left main occlusion and 75% stenosis of right coronary artery].

Patients with significant stenosis (>50%) of the left main coronary artery (LM) are considered high risk for coronary artery bypass grafting (CABG). LM disease is mainly considered a relative contraindication for off pump coronary artery bypass grafting (OPCAB) because of the reduced tolerancy of hamodynamic disturbances which occurs during mobilisation and exposition of the heart, necessary for this type of operations. The aim of the study is to show feasibility of OPCAB for patient with occlusion of the LM and 75% stenosis of the right coronary artery.

[Beating heart surgery in the treatment of stenoses of the main branch of the left coronary artery].

This study reviewed the early experience with off-pump coronary artery bypass surgery in treatment of patients with severe left main coronary artery stenosis. From May 2002-December 2003, 75 patients with significant left main coronary artery stenosis (> or = 50%) underwent coronary artery bypass grafting. 35 patients were operated without the use of cardiopulmonary bypass (OPCAB) and compared with 40 patients operated with the use of cardiopulmonary bypass (ONCAB).

Conversions in off-pump coronary surgery.

Methods: There have been 784 coronary artery bypass grafting (CABG) procedures performed at a new center for treating cardiovascular disease in Tuzla, Bosnia and Herzegovina, and the surgical team has been fully trained in offpump coronary artery bypass (OPCAB) surgery. All surgical patients were considered for on-pump CABG (ONCAB) and OPCAB surgical procedures. Minimally invasive direct coronary artery bypass grafting and robotic procedures were done as OPCAB.

[Coronary artery bypass grafting without use of cardiopulmonary bypass].

Although it is possible to find a number of comparative studies in the world literature discussing the results of coronary artery bypass surgery (CABG) with and without cardiopulmonary bypass (CPB), until now such analysis has not been made in Bosnia and Herzegovina. The main aim of this scientific work was to compare morbidity and mortality, need for blood transfusions, length of stay in the intensive care unit and total length of hospitalisation in two groups of patients operated with these methods. One hundred and four patients with coronary artery disease operated in Cardiovascular Clinic Tuzla, from September, 1998 to September 2002 divided in two groups, were included in this study.

Transit time flow measurements in coronary surgery: the experience from a new center in Bosnia.

Background: A new cardiovascular center in Tuzla, Bosnia Herzegovina was opened for cardiac procedures in September 1998. In the first three years of operation, a total of 440 coronary artery bypass grafting (CABG) procedures were performed there. Off-pump coronary artery bypass (OPCAB) was emphasized as the main tool for surgical revascularization.
