Improving hemodynamics by atrial pacing during off-pump bypass surgery.
To avoid hemodynamic deterioration during tilting of the heart in off-pump surgery, we perform atrial pacing. We describe hemodynamic evaluation of this simple maneuver. ⋯ Atrial pacing increases intraoperative RRs, RRm, CO, and CI and decreases SV and LAP significantly, thus offering stable hemodynamics during off-pump surgery. In the last 400 consecutive off-pump coronary artery bypass grafting procedures, there was only 1 (0.25%) conversion to cardiopulmonary bypass.

Clinical Trial Controlled Clinical TrialMarkers of myocardial ischemia in the evaluation of the effect of left anterior descending coronary artery lesion and collateral circulation on myocardial injury in 1-vessel off-pump coronary bypass surgery.
The purpose of this study was to use serum markers for myocardial tissue damage to evaluate the effect of the severity of left anterior descending artery (LAD) lesions after 1-vessel off-pump coronary artery bypass grafting. ⋯ One-vessel off-pump coronary artery bypass grafting can be performed safely in patients with serious LAD stenosis and borderline antegrade blood flow without the need for any coronary collateral circulation support. A short anastomosis time prevents myocardial injury during off-pump coronary surgery.

A "fast track" approach to cardiac surgery can be defined as a perioperative process involving rapid progress from preoperative preparation through surgery and discharge from the hospital. Although highly individualized among the various heart surgery centers, the fast-track process is a team activity. ⋯ The necessary elements of the fast-track program are choice and the titration of short-acting anesthetic drugs, standardized surgical procedures, early extubation, rewarming and sustained postoperative normothermia, postoperative pain control, early ambulation, alimentation and discharge, and follow-up after discharge. We review the current approaches to some of these aspects of patient care.

Comparative StudyEarly and midterm results after coronary artery bypass grafting with and without cardiopulmonary bypass: which patient population benefits the most?
We present our early and midterm results with off-pump coronary artery bypass grafting (OPCAB) on the beating heart and with conventional coronary artery bypass grafting (CABG) and compare patient outcomes for both procedures. ⋯ OPCAB surgery improved postoperative recovery for the entire patient population without compromising midterm outcome. Compared with conventional CABG, high-risk patients with multimorbidity particularly profit from avoiding cardiopulmonary bypass and show significantly lower hospital mortality.

Comparative StudyMultivessel off-pump coronary artery bypass: analysis of 4953 cases.
To avoid the harmful effects of cardiopulmonary bypass (CPB), cardiac surgeons are using off-pump coronary artery bypass (OPCAB) as an effective alternative to conventional coronary artery bypass grafting (CABG). In the present study, we analyze our results with OPCAB in patients with multivessel coronary artery disease and compare them with those achieved in patients who underwent operations on CPB. ⋯ OPCAB is a safe and effective procedure for patients with multivessel coronary artery disease and is associated with reduced morbidity and mortality. However, large randomized studies with long-term follow-up may show the real benefits of OPCAB compared with CABG on CPB.
