Value of delayed-enhancement cardiovascular magnetic resonance imaging in predicting myocardial viability after surgical revascularization. (1/407)

BACKGROUND: Despite the accepted utility of delayed-enhancement MRI in identifying irreversible myocardial injury, no study has yet assessed its role as a viability tool exclusively in the setting of coronary artery bypass surgery (CABG), and no study has repeated delayed-enhancement MRI late after revascularization. In a clinical trial in which patients underwent CABG by either the off-pump or on-pump surgical technique, we hypothesized that (1) preoperative delayed-enhancement MRI would have high diagnostic accuracy in predicting viability and (2) the occurrence of perioperative myocardial necrosis would affect late regional wall motion recovery. METHODS AND RESULTS: Fifty-two patients undergoing multivessel CABG were studied by preoperative and early (day 6) and late (6 months) postoperative cine MRI for global and regional functional assessment and delayed-enhancement MRI for assessment of irreversible myocardial injury. Preoperatively, 611 segments (21%) had abnormal regional function, whereas 421 segments (14%) showed evidence of hyperenhancement. At 6 months after revascularization, 57% (343 of 611) of dysfunctional segments improved contraction by at least 1 grade. When all preoperative dysfunctional segments were analyzed, there was a strong correlation between the transmural extent of hyperenhancement and the recovery in regional function at 6 months (P<0.001). Of a total of 96 previously dysfunctional but nonenhancing or minimally hyperenhancing myocardial segments that did not improve regional function at 6 months, 35 (36%) demonstrated new perioperative hyperenhancement in the early postoperative MRI scan. CONCLUSIONS: Delayed-enhancement MRI is a powerful predictor of myocardial viability after surgery, suggesting an important role for this technique in clinical viability assessment.  (+info)

On-pump versus off-pump coronary artery bypass surgery in a matched sample of women: a comparison of outcomes. (2/407)

BACKGROUND: Women have consistently higher mortality and morbidity than men after coronary artery bypass grafting (CABG). Whether elimination of cardiopulmonary bypass and performance of coronary artery bypass grafting off-pump (OPCAB) have a beneficial effect specifically in women has not been defined. METHODS AND RESULTS: From January 1998 through March 2002, 21 902 consecutive female patients at 82 hospitals underwent isolated CABG, as reported in an administrative database. Propensity score computer matching was performed based on 13 variables representing patient characteristics and preoperative risk factors to correct for and minimize selection bias. A total of 7376 (3688 pairs) women undergoing CABG surgery were able to be successfully matched. In a propensity score computer-matched cohort, multivariate logistic regression (odds ratio) revealed that women undergoing on-pump surgery had a 73.3% higher mortality (P=0.002) and a 47.2% higher risk of bleeding complications (P=0.019). CONCLUSIONS: In a retrospective analysis of women undergoing CABG, computer-matched to minimize selection bias, off-pump surgery led to decreased mortality and morbidity including bleeding complications.  (+info)

Why is off-pump coronary surgery uncommon in Canada? Results of a population-based survey of Canadian heart surgeons. (3/407)

BACKGROUND: Off-pump coronary artery bypass (OPCAB) is proposed to improve clinical outcomes and decrease resource use. However, off-pump surgery is not widely used in Canada. The purpose of this study was to determine the current use of OPCAB in Canada and determine why surgeons have not adopted this technique. METHODS AND RESULTS: The study was a population-based survey of all adult Canadian cardiac surgeons in practice >1 year. Eligible division heads and surgeons were contacted by mail. Of 19 806 isolated coronary bypass surgeries performed by respondents in Canada last year, 3164 (16.0%) were performed off-pump. More than 50% of Canadian surgeons performed OPCAB in <5% of coronary cases, and only 17% of surgeons performed OPCAB in >25% of coronary cases. Only 4 responding centers performed OPCAB in >25% of cases. Respondents were divided into those who performed <5% of cases off-pump (nonadopters), 5% to 25% off-pump (intermediate users), or >25% off-pump (enthusiasts). Mean number of distal anastomoses in off-pump cases were 1.7+/-0.6, 1.6+/-0.6, and 3.3+/-0.5 for nonadopters, intermediate users, and enthusiasts, respectively (P=0.001). Eleven percent of nonadopters, 55% of intermediate users, and 81% of enthusiasts believed OPCAB improved clinical outcomes (P<0.0001). Only 23% of all respondents felt OPCAB use would increase in the next 5 years. CONCLUSIONS: Concerns regarding incomplete revascularization and lack of proven clinical benefit have limited OPCAB to being performed routinely by only a small number of surgeons in Canada.  (+info)

Role of coronary collaterals in off-pump and on-pump coronary bypass surgery. (4/407)

BACKGROUND: Collaterals limit infarct size, preserve viability, and reduce mortality in patients with acute myocardial infarction. In patients with stable coronary disease, collaterals are associated with less angina and ischemia during angioplasty and fewer ischemic events during follow-up. The role of collaterals has not been studied in patients undergoing off-pump or on-pump bypass surgery. METHODS AND RESULTS: The population consisted of the 281 patients randomized to off-pump or on-pump CABG in the Octopus Study. Collaterals were defined on the baseline angiogram with the Rentrop score and were present in 49% and 51% of the patients in the off-pump and on-pump group, respectively. Perioperative myocardial infarction was defined by a creatine kinase-MB to CK ratio >10% and occurred in 18.2% in the off-pump group and 32.5% in the on-pump group. The unadjusted OR of perioperative myocardial infarction in the presence of collaterals was 0.31 (95% CI 0.17 to 0.84) in the off-pump group and 1.06 (95% CI 0.29 to 3.85) in the on-pump group After adjustment for age, gender, hypertension, hypercholesterolemia, diabetes, multivessel disease, ventricular dysfunction, incomplete revascularization, and ischemic time, the OR was 0.34 (95% CI 0.14 to 0.84) in the off-pump group and 1.28 (95% CI 0.30 to 5.40) in the on-pump group, respectively. Kaplan-Meier estimates of event-free survival at 1 year were 87% in patients with and 69% in those without collaterals after off-pump CABG. These estimates were 66% and 63%, respectively, after on-pump CABG. CONCLUSIONS: Collaterals protect against perioperative myocardial infarction during off-pump surgery but not during on-pump surgery and are associated with a better 1-year event-free survival.  (+info)

Cardiomed coronary flow meter for prevention of early occlusion in aortocoronary bypass grafting. (5/407)

INTRODUCTION: The number of patients undergoing technically demanding off-pump myocardial revascularization is increasing, these days. Some researchers question the quality of the aortocoronary bypasses done on the beating heart and consequently their good patency. MATERIAL AND METHODS: 50 consecutive patients underwent off pump coronary surgery using sequential bypass technique, at our department. The quality of constructed grafts was evaluated using the CardioMed Trace System (CM4008, Medi-Stim As, Oslo, Norway) (TTFM). RESULTS: All sequential bypasses showed good per-operative quality with a mean fl ow of 69.4 ml/min. CONCLUSION: TTFM seems to be an effective tool for the per-operative aortocoronary bypass patency verification and should help to prevent early graft occlusion. ABBREVIATIONS: TTFM transit time flow meter.  (+info)

One-year coronary bypass graft patency: a randomized comparison between off-pump and on-pump surgery angiographic results of the PRAGUE-4 trial. (6/407)

BACKGROUND: Off-pump coronary bypass surgery has become a widely used technique during recent years. However, limited data are available with regard to 1-year patency of bypass grafts implanted on the beating heart in unselected consecutive bypass surgery candidates. The aim of this study was to compare 1-year angiographic patency of bypass grafts done on the beating heart (off pump) with those done classically (on pump). METHODS AND RESULTS: The PRAGUE-4 trial randomized 400 consecutive nonselected cardiac surgery candidates into group A (on pump; n=192) and group B (off pump; n=208). One-year follow-up coronary angiography was done in 255 patients. The arterial graft patency after 1 year was 91% in both groups. Saphenous graft patency was 59% (on pump) versus 49% (off pump; P=NS). Saphenous graft patency per patient was lower in the off-pump group: 0.7 patent anastomosis per patient versus 1.1 patent anastomosis in the on-pump group (P<0.01). There were 46% on-pump patients with all grafts patent versus 52% off-pump patients (P=NS). Grafts anastomosed distally to collateralized chronic total occlusions of native coronary arteries remained patent in 100% on the left anterior descending artery compared with 23% on other arteries (P<0.0001). CONCLUSIONS: The patency of arterial coronary bypass grafts done on the beating heart is excellent and equal to grafts done on pump. The off-pump procedure in the unselected patient population results in fewer patent saphenous grafts per patient.  (+info)

Off-pump coronary artery bypass grafting: single center experience with 1,000 consecutive patients. (7/407)

BACKGROUND: Advances in surgical techniques and retractor-stabilizer devices allowing access to all coronary segments have resulted in increased interest in off-pump coronary artery bypass. The residual motion in the anastomotic site and potential hemodynamic derangements, however, render this operation technically more demanding. OBJECTIVES: To evaluate the OPCAB experience in a single Israeli center. METHODS: Between 2000 and 2003 in our institution, 1,000 patients underwent off-pump operations. Patients were grouped by the type of procedure, i.e., minimally invasive direct coronary artery bypass or mid-sternotomy OPCAB. RESULTS: One hundred MIDCAB operations were performed. Of the 900 OPCAB, 767 patients received multiple grafts with an average of 2.6 +/- 0.6 grafts per patient (range 2-4) and the remaining patients underwent single grafting during hybrid or emergency procedures. In the multiple-graft OPCAB group, complete revascularization was achieved in 96%. Multiple arterial conduits were used in 76% of the patients, and total arterial revascularization without aortic manipulation, using T-graft (35%) or in situ configurations, was performed in 61%. The respective rates for early mortality, myocardial infarction and stroke in the MIDCAB were 1%, 0% and 2%, and 2%, 1.3% and 0.9% in the multiple-vessel OPCAB groups. Multivariate analysis identified renal dysfunction (odds ratio 11.5, confidence interval 3.02-43.8; P < 0.0001) and emergency operation (OR 8.74, CL 1.99-38.3; P = 0.004) as predictors of mortality. The proportion of off-pump procedures increased from 9% prior to the study period to 59%. CONCLUSIONS: The use of OPCAB does not compromise the ability to achieve complete myocardial revascularization. Our procedure of choice is OPCAB using arterial conduits, preferably the 'no-touch' aorta technique.  (+info)

Off-pump bypass surgery: the early experience, 1969-1985. (8/407)

This is a review of 733 patients who underwent off-pump bypass surgery of the right coronary artery and left anterior descending coronary artery between 1969 and 1985. Two hundred sixty-four patients underwent single bypass of the left anterior descending coronary artery, and 79 patients underwent single bypass of the right coronary artery. Both the left anterior descending and right coronary arteries were bypassed in 390 patients. In contrast to the present-day use of mechanical devices to stabilize the target vessel, a 4-suture surgical technique was used for this purpose. This technique, which we illustrate, proved less cumbersome and made the graft anastomosis easy to perform. Our early experience (1969 through 1972) in operating on 199 patients resulted in an operative mortality rate of 4.5% (9/199). From 1973 through 1985, improved patient selection and use of the left internal thoracic artery as the conduit of choice for bypass of the left anterior descending coronary artery reduced the operative mortality rate for 534 patients to 1.3% (7/534). Routine postoperative angiograms were not performed; therefore, the graft patency rate is not available. However, an ongoing 34-year follow-up study of the 264 patients who underwent a single left anterior descending bypass showed the saphenous vein graft to be open in 64.3% (18/28) patients and the left internal thoracic graft in 92.2% (59/64) of patients studied. Seventy-four of the 264 patients in this study were still alive in 2003.  (+info)

In off-pump coronary artery bypass surgery, manipulations on the beating heart can lead to transient interruptions of myocardial oxygen supply, which can generate an accumulation of oxygen-dependent metabolites in coronary venous blood. The objective of this study was to evaluate the reliability of intravascular near-infrared spectroscopy as a monitoring method to detect possible ischemic events in off-pump coronary artery bypass procedures. In 15 elective patients undergoing off-pump myocardial revascularization, intravascular near-infrared spectroscopic analysis of coronary venous blood was performed. NIR signals were transferred through a fiberoptic catheter for signal emission and collection. For data analysis and processing, a miniature spectrophotometer with multivariate statistical package was used. Signal acquisition and analysis were performed before and after revascularization. Spectroscopic data were compared with hemodynamic parameters, electrocardiogram, transesophageal echocardiography and

Beating-heart, off-pump coronary artery bypass surgery does not require stopping the heart, which offers several benefits for the patient.
The intense debate of earlier years between off-pump coronary artery bypass (OPCAB) grafting and conventional coronary artery bypass grafting (CABG) with the use of cardiopulmonary bypass (CPB) has recently given place to a more balanced and targeted approach to surgical coronary revascularisation. Baseline patient characteristics, coronary and aortic pathology and, most importantly, surgeon experience and training are currently the main factors influencing the decision and implementation of OPCAB. In an era where outcomes following CABG are closely monitored and mortality rarely exceeds 3%, the practice of off-pump revascularisation aims at amelioration of morbidity and at achieving equivalent, if not superior, outcomes compared with on-pump CABG. However, a systematic and indepth analysis of the relevant literature highlights an important issue, which is often neglected and could potentially influence decision making in coronary artery surgery: this is intraoperative conversion.1.

Introduction: Acute kidney injury (AKI) is a common postoperative complication of cardiac surgery, which is associated with an increased risk of morbidity and mortality. This study investigated the frequency of postoperative AKI in low risk adult patients undergoing off-pump coronary artery bypass grafting (CABG).Materials & Methods: All consecutive adult patients of American Society of Anesthesiologists (ASA) class II and III, who were transferred to the post-operative cardiac surgery ICU after off-pump CABG and were low risk for AKI from October 2013 to September 2014 at Emam Reza Hospital, Mashhad, Iran were enrolled in this prospective cohort study at a teaching hospital. The patients were explored for AKI development, based on risk-injury-failure-loss- end stage kidney disease (RIFLE) and acute kidney injury network (AKIN) criteria, frequency of metabolic acidosis, hypernatremia, hyperchloremia, and length of stay in ICU.Results: According to the results of the present study, 479 patients with the
Our aim was to assess the efficacy of thoracic epidural anesthesia (EA) followed by postoperative epidural infusion (EI) and patient-controlled epidural analgesia (PCEA) with ropivacaine/fentanyl in off-pump coronary artery bypass grafting (OPCAB). In a prospective study, 93 patients were scheduled for OPCAB under propofol/fentanyl anesthesia and randomized to three postoperative analgesia regimens aiming at a visual analog scale (VAS) score | 30 mm at rest. The control group (n = 31) received intravenous fentanyl 10 μg/ml postoperatively 3-8 mL/h. After placement of an epidural catheter at the level of Th2-Th4 before OPCAB, a thoracic EI group (n = 31) received EA intraoperatively with ropivacaine 0.75% 1 mg/kg and fentanyl 1 μg/kg followed by continuous EI of ropivacaine 0.2% 3-8 mL/h and fentanyl 2 μg/mL postoperatively. The PCEA group (n = 31), in addition to EA and EI, received PCEA (ropivacaine/fentanyl bolus 1 mL, lock-out interval 12 min) postoperatively. Hemodynamics and blood gases were

BACKGROUND: Neurocognitive dysfunction remains a limitation of cardiac surgery with cardiopulmonary bypass. Intraoperative cerebral microembolization is believed to be one of the most important etiologic factors. Using a new generation of transcranial Doppler ultrasonography, we compared the number and nature of intraoperative microemboli in patients undergoing on-pump and off-pump cardiac surgery procedures. METHODS: Bilateral continuous transcranial Doppler monitoring of the middle cerebral arteries was performed in 45 patients (15 off-pump coronary artery bypass grafting, 15 on-pump coronary artery bypass grafting, and 15 open cardiac procedures). All recordings were performed using a multi-range, multifrequency system to allow both measurement of the number and discrimination of the nature of microemboli in the 3 different groups. RESULTS: The median number (interquartile range) of microemboli in the off-pump coronary artery bypass grafting, on-pump coronary artery bypass grafting, and open
OBJECTIVES: Acute kidney injury (AKI) is one of the most frequently occurring complications after off-pump coronary artery bypass graft (OPCAB). Hyperglycaemia is a major, potentially modifiable risk factor of adverse outcome after cardiac surgery known to aggravate organ damage. The aim of this study was to address the association between intraoperative glucose concentration and postoperative AKI in patients who underwent OPCAB. METHODS: The medical records of 880 consecutive patients were retrospectively reviewed. Patients were divided into three groups according to the time-weighted average of intraoperative glucose concentrations (,110, 110-150 and ,150 mg/dl), and the incidence of AKI (increase of serum creatinine to ,2.0 mg/dl and 2 × most recent preoperative value or a new requirement for dialysis) was compared. Multivariate logistic regression analysis was performed to identify independent risk factors for postoperative AKI. RESULTS: The incidence of AKI was higher in patients with a ...

We aim to evaluate in-hospital events and long-term clinical outcomes in patients over 60 years of age with stable coronary artery disease and preserved left ventricular ejection fraction undergoing off-pump or on-pump coronary artery bypass grafting. The MASS III was a single-center randomized trial that evaluate 308 patients with stable coronary artery disease and preserved ventricular function assigned for: 155 to off-pump and 153 to on-pump CABG. Of this, 176 (58.3%) patients were 60 years or older at the time of randomization (90 of-pump and 86 on-pump). The primary short-term end point was a composite of myocardial infarction, stroke, and overall mortality occurring within 30 days after surgery or before discharge, whichever was later. The primary long-term end point was death from any cause within 5 years, non-fatal myocardial infarction between 30 days and 5 years, or additional revascularization between 30 days and 5 years. On-pump CABG had a higher incidence of 30-day composite outcome than

The broken guide wire could get stuck anywhere during coronary artery angiography, but the broken guide wire in the brachial artery is extremely rare. In this report, we describe our experience with a case of off-pump coronary artery bypass (OPCABG) concomitant with the retrieval of a broken guide wire stuck in the brachial artery: a 56-year-old male patient was referred to our hospital because of tri-vessel disease and a broken guide wire stuck in the right brachial artery. He received OPCABG concomitant with the retrieval of the broken guide wire stuck in the brachial artery under general anesthesia. The patient was discharged uneventfully, and 12 months follow-up showed an excellent surgical outcome. Open surgery is an effective means for treating patients with a guide wire stuck in the brachial artery during percutaneous coronary intervention.

Background: Benefits of off-pump CABG (OPCAB) compared with conventional on-pump CABG (CCAB) still has been controversial. However, it is important to investigate which patient subgroups may benefit more from OPCAB rather than CCAB.. Methods and Results: Among the patients undergoing first PCI or CABG enrolled in the CREDO-Kyoto Registry (a registry of first-time PCI and CABG patients in Japan), 2468 patients undergoing CABG were entered into the study (67 ± 9 y.o.). Predicted risk of operative mortality (PROM) of each patient was calculated by logistic EuroSCORE. Patients were divided into tertile based on their PROM. Mortality rates and the incidences of cardiovascular events were compared between CCAB and OPCAB within each PROM tertile using propensity-score analysis. (Table) A total of 1376 patients received CCAB and 1092 did OPCAB. Observed 30-day mortality in whole population was similar between CCAB and OPCAB (odds ratio [95% confidence interval]: 1.18 [0.93-1.51], p=0.17). Observed ...

Clinical data of the two groups were recorded and analyzed including operation time, coronary grafts, incomplete revascularization, postoperative ventilation, perioperative stroke, and low output syndrome, etc ...
Coronary artery bypass surgery is commonly known as CABG. Its a type of heart surgery. Surgeons do this type of surgery to bypass blockages in the coronary arteries.
OBJECTIVES: Around 5-15% of patients undergoing coronary artery bypass grafting (CABG) suffer from preoperative/pre-existing atrial fibrillation (PAF). This is a benign arrhythmia but can affect the outcome of the surgery. The aim of this study was to assess the effect of PAF on the immediate postoperative course of patients undergoing on-pump (ONCAB) vs. off-pump (OPCAB) CABG.. METHODS: Over a 10-year period, data were prospectively entered into the database of our institution. A total of 10,461 patients underwent CABG, of whom 477 (4.6%) were in PAF. We analyzed these patients in two separate groups: group A (n=310) who underwent ONCAB and group B (n=167) who underwent OPCAB. After 4:1 propensity matching and adjusting for the preoperative and operative characteristics of these two groups with patients in SR (sinus rhythm), early, mid- and long-term outcomes of PAF patients were analyzed.. RESULTS: After adjusting for preoperative characteristics, postoperative complications were significantly ...

This study compares the early safety and efficacy of total arterial CABG in off- and on-pump surgery.. Methods: A prospective cohort of all consecutive CABG-only patients from 2003-2012 was analyzed to compare short-term outcomes of off-pump with on-pump patients.. Results: From July 2003 to March 2012, 937 patients underwent CABG with 98% arterial grafts (2727/2782). From April 2008 onward, 79% (322/408) of CABG was performed off-pump. Prior to this only 6% (31/529) of CABG was done off-pump and was mainly for single-vessel disease or ascending aortic calcification. For off-pump/on-pump respectively TAG was performed in 94% (333/353)/96% (561/584) patients and 98% ...
Off-pump coronary artery bypass grafting is better than on-pump in patients with STEMI underwent surgery within 2 days from onset of symptoms. Surgeons may be reluctant to use OPCAB due to concerns about completeness of myocardial revascularization and graft patency. The aim of this study was to assess long-term clinical outcomes and graft patency in this kind of patients. Participants in two previous randomized studies performed in our institution including 207 STEMI patients underwent emergent or urgent CABG within 48 hours from onset of symptoms were followed after surgery to assess graft patency and major adverse cardiac-related events (MACE). There were 145 patients operated in on-pump and 62 patients in off-pump. Patency was assessed by multidetector computed tomography coronary angiography (MDCTA) with a 64-slice scanner. Two blinded observers classified proximal, body and distal segments of each graft as occluded or not, or grade of stenosis. Clinical follow-up was obtained by our ...
Fifty-nine trials were included, encompassing 8,961 patients, with a mean age of 63.4 and 16% females. There was a significant 30% reduction in the occurrence of postoperative stroke with OPCAB (risk ratio [RR], 0.70; 95% confidence interval [CI], 0.49-0.99). There was no significant difference in mortality (RR, 0.90; 95% CI, 0.63-1.30) or myocardial infarction (pooled RR, 0.89; 95% CI, 0.69-1.13). In the meta-regression analysis, the effect of OPCAB on all of the clinical outcomes was similar regardless of mean age, proportion of females in the trial, number of grafts per patient, and trial publication date.. ...

a Cochrane review concluded that BIS within 40 to 60 may improve anaesthetic delivery and postoperative recovery from relatively deep anaesthesia, and more important that BIS-guided anaesthesia significantly reduces the incidence of intraoperative recall in surgical patients with high risk of awareness (ex. TIVA) [Punjasawadwong et al. Cochrane Database Syst Rev. 4: CD003843, 2007]. The largest study in Cochrane was Myles et al. (2463 patients), the second-largest was only 268 patients. Cochrane did not review Avidan (see below), which was published later.. Myles et al. conducted a randomized, double blind trial of 2463 high risk patients (caesarean section, high-risk cardiac surgery [EF ,30%, cardiac index ,2·1 L/min per m2, severe aortic stenosis, pulmonary hypertension, or undergoing off-pump coronary artery bypass graft surgery], acute trauma with hypovolaemia, rigid bronchoscopy, significant impairment of cardiovascular status and expected intraoperative hypotension requiring treatment, ...
Introduction: The use of coronary artery bypass surgery (CABG) with cardiopulmonary bypass (CPB) or without CPB technique (off-pump) can be associated with different mortality and morbidity and their outcomes remain uncertain. The goal of this study was to evaluate the early outcome of on-pump versus off-pump CABG. Methods: We conducted a retrospective database review of 13866 patients (13560 patients undergoing onpump CABG and 306 patients undergoing off-pump CABG) at Tehran Heart Center between January 2002 and January 2007. We compared preoperative, operative, and postoperative characteristics between them. Results: In-hospital mortality in the on-pump group was 0.8% compared to 0.7% in the off-pump group (P=0.999) and in-hospital morbidity was 11.7% and 6.5%, respectively (OR: 1.533, 95%CI: 0.902-2.605, P=0.114). Postoperative atrial fibrillation was more prevalent in on-pump versus off-pump surgery (6.0% vs 3.0%, P=0.028), however there were no statistical significant differences in other ...
OBJECTIVE:Effective antiplatelet therapy may decrease the risk of complications following off-pump coronary artery bypass surgery (CABG). We prospectively evaluated the safety and early efficacy of a combined regimen of clopidogrel and aspirin starting immediately after off-pump CABG. METHODS: One hundred thirty-five consecutive off-pump CABG patients received clopidogrel (75 mg/day) and ...
A total of 1325 consecutive patients were recruited. During the follow-up period, there were 131 deaths (9.8%), 146 repeat revascularizations (11.0%) and 229 major adverse cardiac events (17.2%). The 18-year freedom from major adverse cardiac events was 62.6 ± 9.3%, 62.5 ± 6.3% and 53.9 ± 11.0%, respectively. Multivariable models showed that a left ventricular ejection fraction ≤35%, chronic obstructive pulmonary disease, peripheral vascular disease (P , 0.001), chronic kidney disease and age ≥80 years (P = 0.002) were independent predictors of diminished long-term survival. Moreover, peripheral vascular disease and off-pump coronary artery bypass (both, P , 0.001) predicted repeat revascularization. Finally, age ≥80 years, peripheral vascular disease, left ventricular ejection fraction ≤35%, off-pump coronary artery bypass and chronic pulmonary obstructive disease were independent predictors of major adverse cardiac events during the long-term follow-up period (all, P , 0.001 ...
Coronary artery bypass grafting (CABG) using in situ skeletonized arterial conduits with an off-pump technique is a high quality and minimally invasive procedure. The internal thoracic artery (ITA) is the most reliable conduit as grafting the left anterior descending artery and circumflex arteries with bilateral ITAs leads to better long-term patient outcomes. In this study, we demonstrated the feasibility and usefulness of off-pump coronary artery bypass grafting surgery using bilateral ITAs. A total of 217 consecutive CABG cases using skeletonized ITA grafts were studied and they were divided into 2 groups are using unilateral ITA (UITA, n 104) and the other using bilateral ITA (BITA, n 113). OPCAB was completed in 94% (98/104) in the UITA group and in 99% (112/113) in the BITA group. The mean number of distal anastomoses per patient was 3.02 in the UITA group and 3.63 in the BITA group. The ITAs were used in situ in 100% (104 ITAs) in the UITA group and in 96% (217 ITAs) in the BITA group. ...

Patients assigned to off-pump coronary artery bypass grafting (CABG) have a lower risk of acute kidney injury (AKI) but no reduction in the rate of reduced kidney function 1 year later, reports a study in the Journal of the American Medical Association.
CORONARY: off-pump and on-pump CABG similar The largest trial ever to compare off-pump and on-pump coronary artery bypass surgery (CABG) has shown no difference between the two techniques in terms of the primary composite end point. There were, however, some differences in certain end points, leading to the suggestion that the decision as to which approach to choose could be individualised with each patient. Table 1. Main results from the CORONARY trial The CORONARY trial enrolled 4,752 patients who were randomised to off-pump or on-pump surgery. At 30 days the primary end point - a composite of death, myocardial infraction (MI), kidney fai. ...
Over time, off-pump bypass surgery grafts may fail. This eMedTV resource discusses graft failure and off-pump bypass surgery, including how long grafts typically last and tips that can help delay graft failure after surgery.
AIMS: The benefits of off-pump coronary artery bypass (OPCAB) continue to be debated, in part due to the fact that pooled effects fail to consider differences in trial and patient characteristics. We sought to analyse the contemporary evidence for OPCAB vs. conventional coronary artery bypass (CCAB), incorporating recent larger trials, and adjusting for differences in trials using a technique known as meta-regression. METHODS AND RESULTS: We systematically reviewed MEDLINE, EMBASE, and the Cochrane database for published and unpublished randomized trials of OPCAB vs ...

OPCAB (off pump coronary artery bypass) has become a preferred technique of coronary revascularization in India, and more so in the East. This technique was restarted by Buffalo and Bennetti who had published their results in 1985. Since then, there has been a great enthusiasm among coronary surgeons to develop and standardize this technique of CABG (coronary artery bypass grafting). In the late nineties, nearly all the coronary centers in India started performing this technique. But, by the early 2000, only a few surgeons continued this practice. Only those who could perform this OPCAB technique in nearly 100% of their patients continued this and the rest of them returned back to the conventional on pump CABG. To attain this result, we had to re-engineer our technique of anesthesia, surgical technique, stabilization, and positioning of the heart to enable us to perform OPCAB in all patients who needed CABG. We have analyzed our last 3000 patients operated by the same surgeon (Dr MPV), in the same

Authors: Eun-Ho Lee, M.D. et al. Anesthesiology 5 2016, Vol.124, 1001-1011. Background: Hypoalbuminemia may increase the risk of acute kidney injury (AKI). The authors investigated whether the immediate preoperative administration of 20% albumin solution affects the incidence of AKI after off-pump coronary artery bypass surgery.. Methods: In this prospective, single-center, randomized, parallel-arm double-blind trial, 220 patients with preoperative serum albumin levels less than 4.0 g/dl were administered 100, 200, or 300 ml of 20% human albumin according to the preoperative serum albumin level (3.5 to 3.9, 3.0 to 3.4, or less than 3.0 g/dl, respectively) or with an equal volume of saline before surgery. The primary outcome measure was AKI incidence after surgery. Postoperative AKI was defined by maximal AKI Network criteria based on creatinine changes.. Results: Patient characteristics and perioperative data except urine output during surgery were similar between the two groups studied, the ...
INTRODUCTION: Open Heart Surgery (OHS) is not commonly practiced in Nigeria and most patients who require OHS are referred abroad. There has recently been a resurgence of interest in establishing OHS services in Nigeria but the cost is unknown. The aim of this study was to determine the direct cost of OHS procedures in Nigeria. METHODS: The study was performed prospectively from November to December 2011. Three concurrent operations were selected as being representative of the scope of surgery offered at our institution. These procedures were Atrial Septal Defect (ASD) Repair, Off Pump Coronary Artery Bypass Grafting (OPCAB) and Mitral Valve Replacement (MVR). Cost categories contributing to direct costs of OHS (Investigations, Drugs, Perfusion, Theatre, Intensive Care, Honorarium and Hospital Stay) were tracked to determine the total direct cost for the 3 selected OHS procedures. RESULTS: ASD repair cost $ 6,230 (Drugs $600, Intensive Care $410, Investigations $955, Perfusion $1080, Theatre $1360,

Off-pump CABG eliminates the need to insert a tube called a cannula into the aorta, to cross-clamp the aorta, connect the patient to the heart-lung machine, and stop and restart the heart, suggesting that patients would do better with this approach. However, small randomized clinical trials and meta-analyses have not been able to determine conclusively whether one CABG technique has better outcomes than the other. The CORONARY trial, conducted at 79 centers in 19 countries, compared the risks and benefits of off-pump and on-pump bypass in the largest patient population studied to date. While the CORONARY trial was recruiting patients, data from the ROOBY (Randomized On/Off Bypass) trial were published showing poor results for off-pump bypass ...
Coronary artery disease (CAD) was evaluated by noninvasive examination in abdominal aortic aneurysm (AAA) patients. A simultaneous operation or a 2-staged operation was performed depending on the seriousness of the condition when both diseases were combined. A total of 36 patients underwent elective repair of AAA between 1996 and 2001. Coronary angiography (CAG) was performed only in patients with suspected CAD by dipyridamole myocardial scintigraphy. Significant CAD was found in 8 patients. Simultaneous operation was performed in 4 patients, and off-pump coronary artery bypass grafting (OPCAB) was performed in all cases of simultaneous operation. In 4 patients receiving 2-staged operations, 1 standard coronary artery bypass grafting (CABG), 1 OPCAB and 2 percutaneous transluminal coronary angioplasties (PTCA) were performed prior to AAA surgery. Twenty-eight patients underwent only AAA operation. Though there were no incidents of perioperative myocardial infarction or cardiac related deaths in ...
Ischemic preconditioning induces tolerance against ischemia-reperfusion injury prior a sustained ischemic insult. In experimental studies, exposure to hyperoxia for a limited time before ischemia induces a low-grade systemic oxidative stress and evokes an (ischemic) preconditioning-like effect of the myocardium. We hypothesised that pre-treatment by hyperoxia favours enchanced myocardial protection described by decreased release of cTn T in the 1st postoperative morning and reduces the release of inflammatory cytokines. Forty patients with stable coronary artery disease underwent coronary artery bypass grafting with cardiopulmonary bypass. They were ventilated with 40 or |96% oxygen for 60 minutes followed by by 33 (18-59) min normoxia before cardioplegia. In the 1st postoperative morning concentrations of cTnT did not differ between groups ((0.44 (0.26-0.55) ng/mL in control and 0.45 (0.37-0.71) ng/mL in hyperoxia group). Sixty minutes after declamping the aorta, ratios of IL-10/IL-6 (0.73 in controls

Background: The elderly population (age ,70 years) incurs greater mortality and morbidity following CABG. OPCAB may mitigate these otucomes. A retrospective analysis of the results of OPCAB in this population was performed. Methods: We reviewed the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) database for elderly patients (n=12697) undergoing isolated CABG surgery and compared the ONCAB (n=11676) with OPCAB (n=1021) technique. Preoperative and intraoperative risk factors, and postoperative outcomes were analysed. Survival analyses was performed after cross-matching the database with the national death registry to identify long-term mortality. Results: High-risk patients were more prevalent in the ONCAB group (p,0.05). OPCAB patients received fewer distal anastomoses than ONCAB patients (2.4±1.1 vs 3.3±1.0, p,0.001). Thirty-day mortality and stroke rates between OPCAB and ONCAB were not significantly different (2% vs 2.5% and 1.1% vs 1.8%, respectively). There ...

The entire body of work with MEI to this point has been carried out in nonhuman animal subjects and excised tissue samples. In this study we measured MEI clinically for the first time in human patients who were undergoing off-pump coronary artery bypass (OPCAB) surgery. Our patient population had a 70-100% stenosis of the coronary artery targeted for bypass. We measured MEI continuously during surgery and at 3, 6, 24 and 72hrs postop from two temporary pacing electrodes attached to heart. MEI increased with occlusion of the diseased artery prior to bypass. The percent increase from baseline was correlated to the percent stenosis of the artery. MEI ...

The ethics committee of Copenhagen County approved the study, and all patients gave written informed consent.. Twenty-five patients without heart valve pathology and in sinus rhythm, scheduled for adult cardiac surgery [coronary artery bypass grafting (CABG) or off-pump coronary artery bypass (OPCAB)], were included in the study. The patients were anaesthesized with induction doses of fentanyl 5-10 μg/kg, midazolam 2-5 mg and pancuronium 0.1 mg/kg, and anaesthesia was continued with enflurane 0.8-1.2% or sevoflurane 1-2% inspired in oxygen. During extracorporeal circulation, anaesthesia was maintained with propofol 200-300 mg/h. All patients were normothermic and normoventilated (PaCO2 between 4.5 and 6.0 kPa) during the study.. A 7.5F PA-TD catheter (Paceport®, Edwards, Copenhagen, Denmark) was inserted via an internal or external jugular vein and advanced until a typical pulmonary artery pressure contour, measured from the tip of the catheter, was evident.

All patients who received at least 1 unit of plasma intraoperatively or during the first 5 postoperative days were studied. They were divided into 3 groups (only younger plasma, ...
There are limitations to the conclusions that can be drawn from this study. Firstly, the comparisons we have made here are not an attempt to estimate either the effectiveness of coronary artery bypass surgery, or the relative balance of benefits and risks associated with early intervention for particular patients. There is clear evidence from randomised controlled trials that an initial strategy of coronary artery bypass surgery is associated, in the long term, with reduced mortality rates in patients with significant left main-stem stenosis, three vessel disease and proximal left anterior descending artery disease.2 However, it should be remembered that, on average, coronary artery bypass surgery prolongs life by only 4.26 months.2 Secondly, the six month postoperative period analysed here accentuates mortality risk associated with the procedure itself; for people who would benefit prognostically from surgery, the total risk faced is the sum of the risk while waiting plus the postoperative ...
DISCUSSION. CABG has become the gold standard for the treatment of coronary artery disease involving multiple vessels, and it consists of on-pump CABG and off-pump CABG. In the early 1980s, two surgeons published their extensive series of off-pump CABG in patients who received grafts in the LAD and the main RCA, but with more limited and difficult grafting of coronary arteries on the posterior and lateral walls[15,16]. On-pump CABG provides a motionless operative field, but it can be associated with a number of complications, such as myocardial ischemic injury, strokes, coagulation, and inflammatory responses[17,18]. To the present, it has been reported that the advantage of sequential coronary artery bypass technology is that it can save grafts, reduce proximal anastomosis, shorten the operation time, provide a more complete vascularization, and have a satisfactory long-term patency rate[19,20]. It is more accurate to determine the direction and length of the bridge between anastomoses. There ...
Off-pump CABG is a type of open heart surgery or beating heart surgery. This form of surgery is a type of coronary artery bypass graft which is done for coronary heart disease. Off-pump CABG does not require a cardiopulmonary bypass, which means that the heart will continue to beat with a heart-lumg machine.. Due to advanced technology, the surgeon can stop only a part of the heart during off-pump bypass. There are many procedures of coronary heart disease that is done off-pump to help patients with other sickly conditions such as liver cirrhosis, aortic calcification, poor renal function, compromised pulmonary system. This procedure helps to reduce the complications and risks associated with the condition. Remember, off-pump surgery evades any kin d of side effects post surgery.. ...
This 3D medical animation shows a coronary artery bypass graft (CABG) procedure used to combat coronary artery disease. Beginning with a midline sternal incision, the heart is connected to a perfusion machine which will take over the duties of the heart while the surgery takes place. Two different grafts are used to bypass the blocked coronary arteries: the internal thoracic artery from inside the chest wall, and the saphenous vein from the leg. After the procedure, the heart is shocked to restart its beating. A drainage tube is left at the incision site to drain away excess fluid. The animation continues to show two other types of approaches to a coronary artery bypass graft, off-pump bypass surgery and minimally invasive bypass surgery.
Heart Port Surgery include minimally invasive direct coronary artery bypass, Off-pump coronary artery bypass, valve repair and Lead placement.
