BACKGROUND: -Prophylactic exclusion of the left atrial appendage (LAA) is often performed during cardiac surgery ostensibly to reduce the risk of stroke. However, the clinical impact of LAA closure in humans remains inconclusive. METHODS: -Out of 10,633 adults who underwent CABG and/or valve surgery between January 2000 and December 2005, 9,792 patients with complete baseline characteristics, surgery procedure and follow-up data were included in this analysis. A propensity-score matching analysis based on 28 pretreatment covariates was performed and 461 matching pairs were derived and analyzed to estimate the association of LAA closure with early postoperative atrial fibrillation (POAF) (AF ≤30 days of surgery), ischemic stroke and mortality...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether continuation of administration of preoperative aspirin until the day of coronary artery bypass grafting (CABG) could minimize postoperative mortality, prevalence of postoperative myocardial infarction (MI) with or without influence on postoperative bleeding, packed red blood cell (PRBC) transfusion and reoperation for bleeding. Altogether, 662 papers were found using the reported search, 7 of which represented the best evidence to answer the clinical question...

Background We previously reported that there was no significant difference at 30 days or at 1 year in the rate of the composite outcome of death, stroke, myocardial infarction, or renal failure between patients who underwent coronary-artery bypass grafting (CABG) performed with a beating-heart technique (off-pump) and those who underwent CABG performed with cardiopulmonary bypass (on-pump). We now report the results at 5 years (the end of the trial). Methods A total of 4752 patients (from 19 countries) who had coronary artery disease were randomly assigned to undergo off-pump or on-pump CABG...

BACKGROUND: Bilateral internal thoracic artery (BITA) grafting in patients with diabetes mellitus is controversial because of a higher risk for sternal infection. The purpose of this study is to compare the outcome of BITA grafting to that of single ITA (SITA) grafting in patients with diabetes. METHODS: Between 1996 and 2010, 964 diabetic patients with multivessel disease who underwent primary coronary artery bypass graft surgery with BITA were compared with 564 patients who underwent coronary artery bypass graft surgery with SITA and saphenous vein grafts...

Patients affected by diabetes usually have extensive coronary artery disease. Coronary revascularization has a prominent role in the treatment of coronary artery disease in the expanding diabetic population. However, diabetic patients undergoing coronary artery bypass grafting or percutaneous coronary intervention experience worse outcomes than nondiabetic patients. Several studies comparing coronary artery bypass grafting vs percutaneous coronary intervention in subgroups of diabetic patients demonstrated a survival advantage and fewer repeat revascularization procedures with an initial surgical strategy...

BACKGROUND: The effects of intra-aortic balloon pump (IABP) usage in patients with acute myocardial infarction remain controversial. This study sought to evaluate the outcomes of IABP usage in these patients. METHODS: Medline, EMBASE, and other internet sources were searched for relevant clinical trials. The primary efficacy endpoints (in-hospital, midterm, and long-term mortality) and secondary endpoints (reinfarction, recurrent ischemia, and new heart failure in the hospital) as well as safety endpoints (severe bleeding requiring blood transfusion and stroke in-hospital) were subsequently analyzed...

A hybrid procedure of beating-heart coronary artery bypass grafting (CABG) with the concomitant use of cardiopulmonary bypass termed on-pump beating-heart CABG (ON-BH CABG) has emerged as an alternative for high-risk patient populations. Although several studies have reported the advantage of ON-BH CABG in high-risk patients, the clinical benefit of ON-BH CABG is still under discussion. Here, we performed a meta-analysis of the data derived from published studies comparing the clinical outcomes of ON-BH CABG with that of conventional arrested heart CABG...

OBJECTIVES: Bilateral internal thoracic artery (BITA) bypass provides long-term survival benefits over strategies that use single internal mammary arteries during coronary artery bypass grafting (CABG). However, the rate of adoption of this strategy remains very low. Moreover, optimal BITA configuration and the use of cardiopulmonary bypass still remain a matter of debate. We investigated the long-term results of a coronary revascularization strategy, utilising exclusively BITA-Y composite grafts using off-pump platform and sequential anastomoses...

This meta-analysis investigated the effects of preoperative prophylactic intraaortic balloon pump placement on postoperative renal function and short-term death of high-risk patients undergoing coronary artery bypass grafting. We found that preoperative prophylactic intraaortic balloon pump support reduced the incidence of coronary artery bypass grafting-associated acute kidney injury and short-term death and dramatically decreased the incidence of postoperative renal replacement therapy by 82% compared with high-risk patients without the procedure...

BACKGROUND: We studied long-term survival using bilateral internal thoracic artery (BITA) grafting in a T-configuration exclusively versus using single internal thoracic artery (SITA) grafting in patients with multivessel disease. METHODS: Consecutive coronary operations performed at a single center between 1996 and 2014 were reviewed. Long-term survival among patients receiving coronary revascularization exclusively with BITA grafting in a T-configuration (n = 2,098) versus SITA grafts plus other types of conduits (saphenous vein graft [SVG] and radial artery [RA]) grafts (n = 1,659)...

BACKGROUND: There are no data available on specific causes of death from randomized trials that have compared coronary artery bypass grafting (CABG) with percutaneous coronary intervention (PCI). OBJECTIVES: The purpose of this study was to investigate specific causes of death, and its predictors, after revascularization for complex coronary disease in patients. METHODS: An independent Clinical Events Committee consisting of expert physicians who were blinded to the study treatment subclassified causes of death as cardiovascular (cardiac and vascular), noncardiovascular, or undetermined according to the trial protocol...

BACKGROUND: Bilateral internal mammary artery (BIMA) grafting has been associated with improved long-term outcomes after CABG. We sought to evaluate the early results and long-term survival among coronary artery bypass graft patients who underwent in-situ BIMA grafting with the radial artery (RA) as an additional arterial conduit compared with those who underwent BIMA with additional saphenous vein graft (SVG). METHODS: Between 1991 and 2013, 1,750 consecutive patients with triple-vessel disease or left main plus right coronary system disease underwent primary isolated in-situ BIMA grafting with at least one internal mammary artery to the left anterior descending artery...

Spasm of arterial grafts in coronary artery bypass grafting surgery is still a clinical problem, and refractory spasm can occasionally be lethal. Perioperative spasm in bypass grafts and coronary arteries has been reported in 0.43% of all coronary artery bypass grafting surgery, but this may be an underestimate. Spasm can develop not only in the internal mammary artery but more frequently in the right gastroepiploic and radial artery. The mechanism of spasm can involve many pathways, particularly those involving regulation of the intracellular calcium concentration...

BACKGROUND: Skeletonization is a technique of bilateral internal thoracic artery (BITA) harvest that preserves sternal blood flow. We sought to identify the relationship of skeletonization and sternal wound infection in a population undergoing BITA harvest. METHODS: Demographics and outcomes were recorded from patients undergoing coronary artery bypass graft surgery with BITA using either skeletonized (n = 531) or nonskeletonized (n = 970) techniques. The primary outcome was total infection...

BACKGROUND: Treatment of multivessel coronary artery disease with traditional single-arterial coronary artery bypass graft (SA-CABG) has been associated with superior intermediate-term survival and reintervention compared with percutaneous coronary intervention (PCI) using either bare-metal stents (BMS) or drug-eluting stents (DES). OBJECTIVES: This study sought to investigate longer-term outcomes including the potential added advantage of multiarterial coronary artery bypass graft (MA-CABG)...

BACKGROUND: There is ongoing debate regarding the efficacy of the radial artery (RA) as an aortocoronary conduit, with few solid data regarding long-term clinical results. We sought to determine if the use of the RA as the second arterial conduit, beside left internal thoracic artery (LITA), would improve long-term clinical outcome after CABG as compared to saphenous vein graft (SVG). METHODS: Between March 2001 and November 2003, 200 patients underwent isolated CABG and were randomized in 1:1 fashion to receive either LITA and RA grafts or LITA and SVGs...

Stable coronary artery disease is the most common clinical manifestation of ischaemic heart disease and a leading cause of mortality worldwide. Myocardial revascularisation is a mainstay in the treatment of symptomatic patients or those with ischaemia-producing coronary lesions, and reduces ischaemia to a greater extent than medical treatment. Documentation of ischaemia and plaque burden is fundamental in the risk stratification of patients with stable coronary artery disease, and several invasive and non-invasive techniques are available (eg, fractional flow reserve or intravascular ultrasound) or being validated (eg, instantaneous wave-free ratio and optical coherence tomography)...

OBJECTIVE: At this consensus conference, we developed evidence-informed consensus statements and recommendations on the practice of off-pump coronary artery bypass graft (OPCAB) by systematically reviewing and performing meta-analysis of the randomized controlled trials (RCTs) comparing OPCAB and conventional coronary artery bypass (CCAB). METHODS: All RCTs of OPCAB versus CCAB through April 2013 were screened, and 102 relevant RCTs (19,101 patients) were included in a systematic review and meta-analysis (15 RCTs of 9551 high-risk patients; and 87 RCTs of 9550 low-risk patients) in accordance with the Cochrane Collaboration and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology...

BACKGROUND: In previous guidelines, intra-aortic balloon pump (IABP) use was strongly recommended in the treatment of cardiogenic shock in the context of acute myocardial infarction. The recent IABP-SHOCK II trial demonstrated no benefit in short- and medium-term mortality with the use of IABP. It was our objective to evaluate in a real life nationwide population of patients with acute myocardial infarction the impact of IABP in short- and medium-term mortality. METHODS: We included patients admitted with acute myocardial infarction in Killip class IV in the first 24 hours, all submitted to urgent coronary angiography...

OBJECTIVES: Previous research suggests that platelet transfusion is associated with adverse events after coronary artery bypass grafting (CABG). The aim of the current analysis was to verify this hypothesis. METHODS: Data from 6745 consecutive patients undergoing CABG from 2006 through 2012 were collected. Patients receiving platelet transfusions intraoperatively or postoperatively in the intensive care unit were compared with control patients. To adjust for possible confounders, propensity score matching and conditional regression analyses were performed...
