Long-Term Survival After Off-Pump Coronary Artery Bypass Grafting.

Background: The aim of this study was to compare the long-term survival rates of patients undergoing isolated first-time coronary artery bypass grafting (CABG) by off-pump CABG with the long-term survival rates in patients undergoing CABG using cardioplegic cardiopulmonary bypass techniques.

Methods: All patients undergoing isolated CABG at a single center (Manchester Heart Centre, Manchester, United Kingdom) between 2000 and 2014 were included. Propensity score matching was performed on the basis of on demographic variables.

A meta-analysis of computerized tomography scan for reducing complications following repeat sternotomy for cardiac surgery.

Cardiac reoperation carries additional risks compared with surgery in patients who are sternotomy-naïve. To identify if preoperative computerized tomography (CT) can reduce this risk, we performed a systematic review of the literature and meta-analysis. Literature search identified 178 studies of which 4 retrospective cohort studies incorporating 900 patients met inclusion criteria.

Effect of risk-adjusted, non-dialysis-dependent renal dysfunction on mortality and morbidity following coronary artery bypass surgery: a multi-centre study.

Objective: As little is known about the impact of non-dialysis-dependent renal dysfunction on short- and mid-term outcomes following coronary surgery we have conducted a large multi-centre study comparing patients with no history of renal dysfunction to those with preoperative renal dysfunction.

Methods: Data was prospectively collected on 19,625 consecutive patients undergoing isolated coronary surgery between 1997 and 2003 from four institutions. Sixty-seven patients had a history of dialysis support prior to coronary surgery, and were excluded from the main analysis of the study.

Limitations of additive EuroSCORE for measuring risk stratified mortality in combined coronary and valve surgery.

Objective: To study the use of the additive and logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) to predict mortality following adult combined coronary artery bypass grafting (CABG) and valve surgery.

Methods: Data were collected prospectively, from all four centres providing adult cardiac surgery in the north west of England, on 1769 consecutive patients undergoing combined CABG and valve surgery between April 1997 and March 2002. Observed in-hospital mortality was compared to predicted mortality as determined by both additive and logistic EuroSCORE.

Coronary surgery in patients with peripheral vascular disease: effect of avoiding cardiopulmonary bypass.

Background: An increasing number of patients with peripheral vascular disease are undergoing coronary artery bypass grafting. Such patients have an increased risk of adverse outcomes. Our aim was to quantify the effect of avoiding cardiopulmonary bypass in this group of patients.

Effect of avoiding cardiopulmonary bypass in non-elective coronary artery bypass surgery: a propensity score analysis.

Objective: Non-elective coronary artery surgery (emergent/salvage or urgent) carries an increased risk in most risk-stratification models. Off-pump coronary surgery is increasingly used in non-elective cases. We aimed to investigate the effect of avoiding cardiopulmonary bypass on outcomes following non-elective coronary surgery.

Surgeon specific mortality in adult cardiac surgery: comparison between crude and risk stratified data.

Objective: As a result of recent failures in clinical governance the government has made a commitment to bring individual surgeons' mortality data into the public domain. We have analysed a database to compare crude mortality after coronary artery bypass surgery with outcomes that were stratified by risk.

Design: Retrospective analysis of prospectively collected data.

Off-pump coronary artery bypass surgery does not reduce gastrointestinal complications.

Objectives: Gastrointestinal (GI) complications following on-pump coronary artery bypass grafting (CABG) are rare, but carry a high mortality rate. Prolonged cardiopulmonary bypass (CPB) has been associated with a higher incidence of such complications. Little is known about the effect of avoiding CPB on GI complications.

Neurological outcomes in coronary surgery: independent effect of avoiding cardiopulmonary bypass.

Background: Recent studies examining neuroprotective effects of off-pump coronary artery bypass grafting (CABG) have shown inconsistent results. We examined our database to quantify the independent effects of avoidance of cardiopulmonary bypass (CPB) and aortic manipulation on neurologic outcomes after CABG.

Methods: A total of 2,327 consecutive cases undergoing isolated CABG between April 1997 and May 2001 were identified at our two institutions.
