STUDY OBJECTIVES Cardiopulmonary bypass (CPB) represents a specific risk factor for renal damage during coronary revascularization. The purpose of this study was to compare the perioperative renal damage in patients undergoing on-pump and off-pump coronary surgery. DESIGN AND PATIENTS The progress and extent of renal damage was prospectively studied in two groups of patients undergoing cardia...

We read with great interest the comprehensive review by Murphy et al. This review of the published literature critically examines the potential benefits of off-pump coronary artery bypass surgery (OPCAB) compared with conventional coronary artery bypass grafting (CABG). A number of important endpoints were examined, such as inflammatory and cellular responses. Their impact on organ dysfunctions...

INTRODUCTION Coronary artery bypass grafting (CABG) is one of the most frequently performed operations around the world. The aim of this study is to evaluate high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-alpha (TNF-alpha) differences between on-pump and off-pump coronary surgery. METHODS In this prospective study, 90 patients with coronary artery disease referred for ...

OBJECTIVE Age is considered to be the strongest predictive factor of postoperative cognitive dysfunction (POCD) after cardiac surgery. Coronary artery bypass grafting (CABG) without the use of cardiopulmonary bypass is considered to be less harmful to the patient, especially in terms of neurological complications. METHODS The study was a sub-study of the randomized best bypass surgery trial t...

In coronary artery surgery the superiority of the internal mammary artery graft in 10-year survival was documented in 1986. In 1999 it was demonstrated that death, reoperation and percutaneous transluminary coronary angioplasty were more frequent in patients undergoing single rather than bilateral internal mammary artery grafting. Today coronary artery bypass grafting surgery is challenged by t...

In modern coronary bypass surgery, new objectives have been set based upon a minimal invasive approach: beating heart surgery is the new trend to follow, although this might not be feasible in more complex cases. In these cases, the beating heart could be supported by a mechanical device, preferably a device with minimal invasive features to fit in this new approach. For this purpose, two intra...

Improvements in techniques in coronary revascularization over the past decade have led to a revival of interest in off-pump coronary artery surgery. A fifth of coronary revascularization procedures are now performed off-pump. Randomized trials comparing off-pump surgery with conventional coronary artery bypass grafting using cardiopulmonary bypass (CPB) mainly included low-risk patients and wer...

BACKGROUND Off-pump coronary artery bypass graft (CABG) surgery is purported to reduce perioperative mortality and morbidity compared with on-pump coronary bypass graft surgery. However, the outcomes of patients for whom an off-pump strategy must be changed to an on-pump procedure during surgery have not been extensively studied. METHODS AND RESULTS The Merged Cardiac Registry (Health Data Re...

OBJECTIVE Widespread application of on-pump revascularization procedures is increasing due to the thought of elimination of untoward effects of cardiopulmonary circuit. Thus, whether off-pump coronary artery surgery eliminates side effects especially related to respiratory functions is still controversial. Although many previous studies have evaluated these respiratory functions, daily comparis...
