The Impact of Aortic Manipulation on Neurologic Outcomes After Coronary Artery Bypass Surgery: A Risk-Adjusted Study
[ PUBLICATION ]
BACKGROUND: Cerebral embolization of atherosclerotic plaque debris caused by aortic manipulation during conventional coronary artery bypass grafting (CABG) is a major mechanism of postoperative cerebrovascular accidents (CVA). Off-pump CABG (OPCABG) reduces stroke rates by minimizing aortic manipulation. Consequently, the effect of different levels of aortic manipulation on neurologic outcomes after CABG surgery was examined.
METHODS: From January 1998 to June 2002, 7,272 patients ...

Beating heart surgery in octogenarians: perioperative outcome and comparison with younger age groups
[ PUBLICATION ]
BACKGROUND: Octogenarians have higher morbidity and mortality rates (9% to 16%) after coronary artery bypass grafting with cardiopulmonary bypass, compared with younger patients.
METHODS: We compared the perioperative outcome and hospital stay after coronary artery bypass grafting without cardiopulmonary bypass (off-pump) from January 1987 to May 1999, among patients older than 80 years (n = 71), patients between 70 and 79 years (n = 228), and patients whose age ranged from 60 to 69 ...

BACKGROUND: Reoperative (redo) coronary artery bypass grafting (CABG) with cardiopulmonary bypass (on-pump) is associated with a higher morbidity and mortality than first-time CABG. It is unknown, however, whether CABG without cardiopulmonary bypass (off-pump) may yield an improved clinical outcome over conventional on-pump redo CABG.
METHODS: We compared the perioperative outcomes of patients with single-vessel disease who underwent on-pump (n = 41) versus off-pump (n = 91) redo CABG ...

BACKGROUND: Postoperative stroke is a serious complication after coronary artery bypass grafting with cardiopulmonary bypass (on-pump), and portends higher morbidity and mortality. It is unknown whether an off-pump cardiopulmonary bypass (OPCAB) approach may yield a lower stroke rate over conventional on-pump coronary artery bypass grafting.
METHODS: From June 1994 to December 2000, OPCAB was performed in 2,320 patients and compared with 8,069 patients who had on-pump coronary artery ...

BACKGROUND AND PURPOSE: Stroke development is a major concern in patients undergoing coronary artery bypass grafting (CABG). Whether asymptomatic severe carotid artery stenosis (CAS) contributes to the development of stroke and mortality in such patients remains uncertain.
METHODS: A retrospective analysis of 878 consecutive patients with documented carotid duplex ultrasound who underwent isolated CABG in our institution from January 2003 to December 2009 was performed. Patients with ...

BACKGROUND AND PURPOSE: Early postoperative stroke is a serious adverse event after coronary artery bypass grafting (CABG). This study sought to investigate risk factors, prevalence, and prognostic implications of postoperative stroke in patients undergoing CABG.
METHODS: We investigated the predictors of postoperative stroke (n=333, 2%) in 16 528 consecutive patients who underwent CABG between September 1989 and June 1999 in our institution. Predictors of postoperative stroke were ...

Clopidogrel administration prior to coronary artery bypass grafting surgery: the cardiologist's panacea or the surgeon's headache?
[ PUBLICATION ]
AIMS: Thrombotic complications after percutaneous coronary intervention procedures have decreased in past years mainly due to the use of clopidogrel antiplatelet therapy. However, the risk of bleeding due to enhanced and irreversible platelet inhibition in patients who will require surgical coronary revascularization instead has not been adequately addressed in the literature. The purpose of this study was to evaluate the effect of pre-operative clopidrogel exposure in ...

Coronary Revascularization Without Cardiopulmonary Bypass Versus the Conventional Approach in High-Risk Patients
[ PUBLICATION ]
BACKGROUND: The premise of coronary revascularization without cardiopulmonary bypass (off-pump coronary artery bypass graft [CABG]) proposes that patient morbidity and, potentially, mortality can be reduced without compromising the excellent results of conventional revascularization techniques (on-pump CABG). High-risk patients may benefit the most from off-pump CABG. The aim of this study was to compare early and mid-term clinical outcomes after off-pump CABG with on-pump CABG in a ...

Chronologic distribution of stroke after minimally invasive versus conventional coronary artery bypass
[ PUBLICATION ]
OBJECTIVES: We sought to investigate whether the chronologic distribution of the onset of stroke occurring after coronary artery bypass graft surgery (CABG) without cardiopulmonary bypass (off-pump CABG) is different from the conventional on-pump approach (CABG with cardiopulmonary bypass).
BACKGROUND: Off-pump CABG has been associated with a lower stroke rate, compared with conventional on-pump CABG. However, it is unknown whether the chronologic distribution of the onset of stroke is ...

BACKGROUND: Premedication with clopidogrel has reduced thrombotic complications after percutaneous coronary revascularization procedures. However, because of the enhanced and irreversible platelet inhibition by clopidogrel, patients requiring surgical revascularization have a higher risk of bleeding complications and transfusion requirements. A principal benefit of surgical coronary revascularization without cardiopulmonary bypass is its lower hemorrhagic sequelae. The purpose of this ...

Comparison of the Quality of Life After Conventional Versus Off‐Pump Coronary Artery Bypass Surgery
[ PUBLICATION ]
PURPOSE: Numerous studies have focused on off-pump coronary artery bypass graft (off-pump CABG) morbidity and mortality outcomes, but few looked at the patient's perception of the technique and its effect on postoperative quality of life (QOL). We investigated and compared postoperative QOL in patients who had undergone either conventional or off-pump CABG myocardial revascularization.
METHODS: During a six-month period, 191 patients who underwent CABG surgery were prospectively studied ...

Association of Body Mass Index With New-Onset Atrial Fibrillation After Coronary Artery Bypass Grafting Operations
[ PUBLICATION ]
BACKGROUND: Postoperative atrial fibrillation (AF) frequently complicates coronary artery bypass grafting (CABG) operations. As the frequency of obesity has increased in the United States, the number of obese patients undergoing CABG has kept pace. This study sought to define the association between body mass index (BMI) and postoperative AF.
METHODS: We studied 12,367 consecutive patients with no history of AF who underwent isolated CABG operations. BMI was stratified according to ...

BACKGROUND: We investigated the impact of extreme obesity (body mass index [kg/m(2)] 50 or greater) on short-term clinical outcomes and report 1-year mortality.
METHODS: Fifty-seven patients were found to have a body mass index of 50 or greater among 14,449 patients who underwent cardiac surgery between July 2000 and June 2007. Multivariable logistic regression analyses were used to assess the independent influence of extreme obesity on the major outcomes.
RESULTS: Of the 57 patients, ...

Postoperative atrial fibrillation (AF) is a frequent adverse event after coronary artery bypass grafting (CABG) and may negatively affect the early clinical outcome. We sought to investigate the risk factors, prevalence, and prognostic implications of postoperative AF in patients submitted to CABG without cardiopulmonary bypass (off-pump). The study population comprised 969 patients, 645 men (67%) and 324 women (33%) who had off-pump CABG at the Washington Hospital Center from January ...
