Abstract
BACKGROUND The aims of this study were to describe early and mid-term morbidity and mortality in octogenarian patients undergoing CABG, to determine if outcomes are comparable to younger patients undergoing the same procedure. METHODS We conducted a retrospective analysis of the first 901 patients who underwent cardiac surgery at a large newly established tertiary hospital in Western Australia from February 2015 to September 2019. Inclusion criteria involved all patients undergoing coronary artery bypass grafting. Exclusion criteria included patients who underwent concomitant valve or aortic procedure. RESULTS From a cohort of 901 patients, 37 octogenarian patients underwent CABG. Octogenarian patients had a higher rate of post-operative transfusion 35.1% versus 21.4% (P = 0.048), a higher rate of post-op acute kidney injury 40.5% versus 17.2% (P < 0.0001), a higher rate of post-operative atrial arrythmia requiring treatment 40.5% versus 22.5% (P = 0.011) and higher rate of return to theatre (13.5% versus 4.7%, P = 0.018), with bleeding/tamponade being the most likely reason (10.8% versus 2.7%). Octogenarian patients had a longer post-operative length of stay (LOS) with a median LOS of 10 versus 7 days (P < 0.0001). There was no increase in hospital readmission rate, in-hospital mortality or 1 year mortality in octogenarian patients. 24-month and 36-month survivals were 95.2% and 89.6% in octogenarians and 95.3% and 91.5% in the younger group. CONCLUSIONS Despite an increase in post-operative morbidity and LOS, there was no difference in hospital readmission, in-hospital mortality or 1 year mortality in octogenarian patients who underwent CABG. CABG is safe and remains an important management option for these patients.

Abstract
OBJECTIVE To describe the risks, outcomes, and trends in patients older than 80 years undergoing coronary artery bypass grafting (CABG). METHODS We retrospectively studied 1283 consecutive patients who were older than 80 years and underwent primary isolated CABG from January 1, 1993, to October 31, 2019, in our clinic. Kaplan-Meier survival probability and quartile estimates were used to analyze patients' survival. Logistic regression models were used for analyzing temporal trends in CABG cases and outcomes. A multivariable Cox proportional hazards regression model was developed to study risk factors for mortality. RESULTS Operative mortality was overall 4% (n=51) but showed a significant decrease during the study period (P=.015). Median follow-up was 16.7 (interquartile range, 10.3-21.1) years, and Kaplan-Meier estimated survival rates at 1 year, 5 years, 10 years, and 15 years were 90.2%, 67.9%, 31.1%, and 8.2%, respectively. Median survival time was 7.6 years compared with 6.0 years for age- and sex-matched octogenarians in the general US population (P<.001). Multivariable Cox regression analysis identified older age (P<.001), recent atrial fibrillation or flutter (P<.001), diabetes mellitus (P<.001), smoking history (P=.006), cerebrovascular disease (P=.04), immunosuppressive status (P=.01), extreme levels of creatinine (P<.001), chronic lung disease (P=.02), peripheral vascular disease (P=.02), decreased ejection fraction (P=.03) and increased Society of Thoracic Surgeons predicted risk score (P=.01) as significant risk factors of mortality. CONCLUSION Although CABG in octogenarians carries a higher surgical risk, it may be associated with favorable outcomes and increase in long-term survival. Further studies are warranted to define subgroups benefiting more from surgical revascularization.

Abstract
Background The optimal revascularization strategy remains uncertain in multivessel coronary artery disease (MVCAD). The durability of the surgical grafts should be weighed against the decreased invasiveness of percutaneous coronary intervention (PCI). Hybrid coronary revascularization (HCR), a combination of PCI and surgery, could be a feasible alternative. This study aimed to investigate the occurrence of major adverse cardiac and cerebrovascular events (MACCE) and all-cause mortality after both endoscopic coronary artery bypass grafting (Endo-CABG) and the HCR procedure. Methods In this single-center retrospective observational study, 347 consecutive patients have been subjected to an Endo-CABG procedure, of which 103 underwent HCR between January 2016 and January 2018. A propensity score matching analysis was performed to match 103 Endo-CABG alone patients to the 103 HCR patients. The Endo-CABG procedure was performed through 3 endoscopic ports (5 mm) in the 2nd, 3rd, and 4th intercostal space and a utility port of 3 cm. Results In both the HCR and matched endo-CABG alone group, the 30-day mortality was acceptable (0% in the HCR group and 1.94% in the matched Endo-CABG alone group, p = 0.155). Additionally, the occurrence of MACCE after a mean follow-up of 1188 ± 538 days was similar in both groups (9.71% and 11.65% for the HCR and matched Endo-CABG alone group, respectively, p = 0.652). Still, the long-term all-cause mortality over this period was significantly higher in the matched Endo-CABG alone group (2.91% after the HCR procedure and 11.65% after matched Endo-CABG alone, p = 0.002). Conclusion HCR has some advantages over Endo-CABG alone regarding the all-cause mortality, cross-clamping time, intensive care unit, and hospital length of stay. Therefore, HCR may be a suitable alternative therapy for patients with MVCAD.

Abstract
BACKGROUND The number of elderly patients undergoing cardiac surgery is increasing. Age greater than 80 years has been identified as a strong independent risk factor for shortand long-term survival. The current study is aimed to identify the impact of preoperative comorbidities on early and late outcomes in older patients undergoing cardiac surgery. METHODS Baseline characteristics, procedurals and postoperative complications of all patients undergoing cardiac surgery at our institution are collected. The current analysis is focused on patients aged at least 80 years at the time of intervention and treated from January 2010 to December 2019. RESULTS In-hospital mortality resulted as 6.3%. Redo intervention [odds ratio (OR) 2.49, 95% confidence interval (CI) 1.13-5.48], chronic obstructive pulmonary disease (COPD) (OR 2.99, 95% CI 1.75-5.12) and peripheral arterial disease (PAD) (OR 2.23, 95% CI 1.30-3.81) were independent baseline predictors of outcome in the multivariate analysis. Prolonged extracorporeal circulation time, need for transfusion and prolonged intubation time strongly and independently predicted in-hospital mortality. During a mean follow-up of 3.6 years 34.3% of patients died and unplanned admission (HR 1.33, 95% CI 1.05-1.67), NYHA class III-IV (HR 1.35, 95% CI 1.12-1.64), diabetes (HR 1.27, 95% CI 1.01-1.59), COPD (HR 1.60, 95% CI 1.25-2.04) and PAD (HR 1.32, 95% CI 1.03-1.71) resulted as independent predictors of all-cause death. CONCLUSION Cardiac surgery is feasible in octogenarians, with an acceptable risk of mortality. Chronological age itself should not be the main determinant of choice while referring patients for cardiac surgical intervention. Comorbidities such as COPD, PAD and diabetes need to be taken into account for risk stratification.

Abstract
The etiology of coronary artery disease (CAD) is multifactorial, stemming from both modifiable and nonmodifiable risk factors such as age. Several studies have reported the effects of age on various outcomes of coronary artery bypass grafting (CABG). This article reviews age-related outcomes of CABG and offers direction for further studies in the field to create comprehensive, evidence-based guidelines for the treatment of CAD. Ninety-two primary sources were analyzed for relevance to the subject matter, of which 17 were selected for further analysis: 14 retrospective cohort studies, 2 randomized clinical trials, and 1 meta-analysis. Our review revealed four broad age ranges into which patients can be grouped: those with CAD (1) below the age of 40 years, (2) between the ages of 40 and 60 years, (3) between the ages of 60 and 80 years, and (4) at or above 80 years. Patients below the age of 40 years fare best overall with total arterial revascularization (TAR). Patients between the ages of 40 and 60 years also fare well with the use of multiarterial grafts (MAGs) whereas either MAGs or single-arterial grafts may be of significant benefit to patients at or above the age of 60 years, with younger and diabetic patients benefitting the most. Arterial grafting is superior to vein grafting until the age of 80 years, at which point there is promising evidence supporting the continued use of the saphenous vein as the favored graft substrate. Age is a factor affecting the outcomes of CABG but should not serve as a barrier to offering patients CABG at any age from either a cost or a health perspective. Operative intervention starts to show significant mortality consequences at the age of 80 years, but the increased risk is countered by maintenance or improvement to patients' quality of life.

Abstract
Identification of microRNAs (miRNA) associated with cardiopulmonary bypass, cardiac arrest and subsequent myocardial ischemia/reperfusion may unravel novel therapeutic targets and biomarkers. The primary aim of the present study was to investigate the effects of cardiopulmonary bypass and temperature of cardioplegic arrest on myocardial miRNA profile in pigs' left ventricular tissue. We employed next-generation sequencing to analyse miRNA profiles in the following groups: (1) hearts were arrested with antegrade warm St Thomas Hospital No. 2 (STH2) cardioplegia (n = 5; STH2-warm, 37 °C) and (2) cold STH2 (n = 6; STH2-cold, 4 °C) cardioplegia. Sixty min of ischemia was followed by 60 min of on-pump reperfusion with an additional 90 min of off-pump reperfusion. In addition, two groups without cardiac arrest (off-pump and on-pump group; n = 3, respectively) served as additional controls. STH2-warm and STH2-cold cardioplegia revealed no hemodynamic differences. In contrast, coronary venous creatine kinase-myocardial band (CK-MB) levels were significantly lower in pigs receiving STH2-warm cardioplegia (p < 0.05). Principal component analysis revealed that cardiopulmonary bypass and cardioplegic arrest markedly affected miRNAs in left ventricular tissue. Accordingly, ssc-miR-122, ssc-miR-10a-5p, ssc-miR-193a-3p, ssc-miR-499-3p, ssc-miR-374a-5p, ssc-miR-345-5p, ssc-miR-142-3p, ssc-miR-424-5p, ssc-miR-545-3p, ssc-miR-30b-5p, ssc-miR-145-5p, ssc-miR-374b-5p and ssc-miR-139-3p were differently regulated by cardiopulmonary bypass (false discovery rate (FDR) < 0.05 versus off-pump group). However, only ssc-miR-451 was differently expressed between STH2-warm and STH2-cold (FDR < 0.05). These data demonstrate for the first time that cardiopulmonary bypass and temperature of cardioplegic solution affected the expression of miRNAs in left ventricular tissue. In conclusion, specific miRNAs are potential therapeutic targets for limiting ischemia-reperfusion injury in patients undergoing cardiac surgery.

Abstract
OBJECTIVE An important advantage of robotic beating-heart totally endoscopic coronary artery bypass (TECAB) is early functional recovery, in which fragile patients like octogenarians (age >80 years) benefit most. The aim of this study was to investigate the safety and feasibility of TECAB in octogenarians. METHODS We retrospectively reviewed patients undergoing TECAB from July 2013 to September 2017 at our institution. Perioperative outcomes of octogenarian patients and that of younger patients were compared. RESULTS Of 308 patients who underwent TECAB, 28 patients (9.1%) were octogenarians (mean age 83.8 ± 3.0 years). Octogenarians had a higher rate of hypertension and atrial fibrillation compared to younger patients. TECAB was successfully performed without conversion to any larger incisions in octogenarians. Mean operative time (299 ± 83 minutes vs 281 ± 89 minutes, P = 0.309) and the rate of multivessel bypass (60.7% vs 58.2%, P = 0.798) were similar between octogenarians and younger patients. New atrial fibrillation was observed more frequently in octogenarians compared to younger patients (35.7% vs 18.6%, P = 0.031). Mean length of hospital stay was similar between the 2 groups (octogenarians: 3.9 ± 1.8 days vs younger patients: 3.5 ± 3.0 days, P = 0.475). Twenty-two octogenarians (78.6%) were discharged directly to home. In-hospital mortality was zero in octogenarians. CONCLUSIONS Robotic beating-heart TECAB had favorable results in octogenarians with acceptable morbidity and mortality and excellent short length of stay similar to younger patients.

Abstract
BACKGROUND In patients undergoing surgical myocardial revascularization for acute myocardial infarction, excellent myocardial protection can be achieved by blood cardioplegia. We investigated the influence of age on cardiac function, metabolism, and infarct size using Buckberg's blood cardioplegia (BCP). METHODS The hearts of male Wistar rats ("adult", age 3 months, n = 8; "senile", age 24 months, n = 8) were excised and mounted on a blood-perfused isolated heart apparatus. An acute myocardial infarction was induced by coronary artery ligation for 30 min before aortic clamping and infusion of Buckberg's BCP. Throughout the experiment, functional parameters were recorded: coronary blood flow (normalized by heart weight), left ventricular peak developed pressure (LVpdP), and positive and negative derived left ventricular pressure over time (dLVPdtmax and dLVPdtmin). Oxygen consumption (MVO2) and lactate production of the hearts were calculated. The infarct size after 90 min of reperfusion (in % of the area at risk) was measured with triphenyl tetrazolium chloride staining of the myocardium. RESULTS The baseline coronary flow normalized by heart weight was significantly lower in the senile hearts (1.6 ± 0.4 ml/(min ∗ g)) compared with the adult hearts (2.0 ± 0.3 ml/(min ∗ g); p = 0.04). After 90 min of aortic clamping, hemodynamic function of senile hearts recovered better than that of adult hearts: LVpdP (adult 57% of baseline [BL]; senile 88% BL; p = 0.044) and dLVPdtmax (adult 74% BL, senile 102% BL; p = 0.12). In contrast, myocardial infarct size was similar between the adult (26%) and senile (21%; p = 0.45) hearts, and coronary flow recovered to a similar extent (55% BL and 58% BL, respectively). During reperfusion, MVO2 (80% BL and 81% BL) and lactate production (1.2 and 1.3 μmol/min) were similar in the two groups. CONCLUSION After acute myocardial infarction in a rat model, hearts recovered function after reperfusion with Buckberg's BCP solution. Hearts from aged animals recovered better than those from younger animals.

Abstract
AIMS Postoperative delirium (POD) and declined cognitive function were common in patients (especially elderly patients) who underwent coronary artery bypass grafting (CABG), which may affect quality of life (QoL). The aim of this study was to determine the relationships among age, POD, declined cognitive function, and QoL in patients who underwent CABG. METHODS Consecutive patients who underwent first time elective CABG and assessed for POD using Confusion Assessment Method for intensive care unit for 5 postoperative days from November 2013 to March 2015 were recruited. A cross-sectional study was conducted during April 2015 to assess their cognitive function and QoL, using the Telephone Interview for Cognitive Status Scale and Medical Outcomes Study 36-Item Short Form Health Survey. The relationships among age, POD, declined cognitive function, and QoL were tested using path analysis. RESULTS Declined cognitive function was associated with poorer QoL. POD was associated with declined cognitive function but was not associated with poorer QoL. Ageing was not associated with QoL but was associated with POD and declined cognitive function. CONCLUSION The QoL of patients developed delirium after CABG is determined by cognitive function after discharge. Necessary strategies should be implemented to prevent POD and declined cognitive function, especially in elderly patients.

Abstract
OBJECTIVES Demographic changes lead to a rising incidence of octogenarians undergoing surgical revascularization of coronary artery disease. Minimally invasive direct coronary artery bypass (MIDCAB) represents a surgical treatment with reduced trauma and without the use of cardiopulmonary bypass. The aim of this study was to evaluate short- and long-term outcomes after MIDCAB in octogenarians. METHODS Between 1998 and 2012, 1060 patients underwent MIDCAB at our department. Among them, 72 patients (6.8%) were older than 80 years at the time of operation. Incidence of major adverse cardiac and cerebrovascular events (MACCEs) was compared between octogenarians [median age 82 (81; 85) years, 63.9% male] and younger MIDCAB patients [median age 64 (56; 70) years, 70.7% male] after 30 days and during follow-up. The impact of demographics and preoperative comorbidities on mortality during follow-up was analysed. RESULTS At baseline, the elderly group presented with a statistically significant higher logistic EuroSCORE I (9.2 vs 2.2%, P < 0.001). Within 30 days, octogenarians showed a mortality rate of 5.6% (younger patients 0.8%, P = 0.006) and an MACCE rate of 5.6% (younger patients 1.3%, P = 0.024). The median follow-up time of 30-day survivors was 5.5 (2.9; 7.6) years and follow-up completeness reached 96.9%. In the elderly group, 1-, 3- and 5-year survival rates were 89, 78 and 63% in comparison with 97, 94 and 90% in the younger group (P < 0.001), respectively. The estimated median survival time in octogenarians was 6.7 (CI 4.854; 8.629) years. Logistic regression showed preoperative renal impairment, peripheral arterial occlusive disease and pulmonary hypertension to have a stronger impact on mortality during follow-up than age above 80 years. CONCLUSIONS MIDCAB represents a safe treatment option in octogenarians and is associated with a good perioperative outcome and satisfying long-term results in octogenarians.

Abstract
PURPOSE The study evaluates the changes in quality of life (QOL) six months after coronary artery bypass grafting (CABG) related to the patients' age. METHODS The total of 243 consecutive patients completed the Nottingham Health Profile Questionnaire part 1 before and six months after CABG. Postoperative questionnaire was completed by 226 patients. Patients were divided into four examined groups (<50, 50-59, 60-69 and ≥70 years), according to their age. RESULTS Six months after CABG, the quality of life in different sections has been significantly improved in most patients.The analysis of the relation between the age and the changes in QOL of patients six months after CABG showed a significant correlation among the patients' age and the improvement of QOL in the sections of physical mobility (r = 0.18, p = 0.008), social isolation (r = 0.17, p = 0.01) and energy ( r = 0.21, p = 0.002). The most prominent improvement was found in older patients. The age was not an independent predictor of QOL deterioration after CABG. CONCLUSIONS The most noticeable improvement of QOL six months after CABG was found in older patients. Age is not the independent predictor of deterioration of QOL after CABG.

Abstract
OBJECTIVE Senescent patients exhibit an elevated perioperative risk for cardiac dysfunction, hemodynamic depression and subsequent cardiac death compared to young patients. Despite the fact that a growing proportion of cardiac surgery patients are octogenarians, cardioplegic regimes remain comparable across patients of all ages. We compared the hemodynamic performance, metabolic parameters and ultrastructural changes in adult and senescent rat hearts after application of Buckberg's blood cardioplegia (BCP) to evaluate differences between the age groups regarding postischemic myocardial function and cellular ultrastructure. METHODS Hearts of adult (young adult group, 3-4 months) and senescent (old group, 24 months) male Wistar rats were excised and inserted into a blood perfused isolated heart apparatus (Langendorff perfusion). After a stabilization period of 30 min, in 16 adult and 16 senescent hearts, Buckberg BCP was administered antegradely and repeated every 20 min. Six young adult and 3 senescent hearts served as ischemia control. After an aortic clamping time of 90 min an antegrade hot shot was administered. During reperfusion ex vivo cardiac functional parameters were recorded, including coronary blood flow, left ventricular developed pressure (LVDP) and velocity of myocardial contraction or relaxation (+/-dp/dt). Oxygen consumption and lactate production of the hearts were calculated. After perfusion fixation, the hearts of five rats in each BCP group and 3 rats in each ischemia group were investigated for cellular edema and mitochondrial damage by morphometry using transmission electron microscopy. RESULTS While recovery of cardiac function after 90 min of unprotected ischemia was significantly impaired in senescent hearts, functional recovery after ischemia protected by BCP was similar in adult and senescent hearts. Mitochondrial ultrastructure was severely damaged in both age groups after 90 min ischemia, but well preserved in both BCP groups. The qualitative analysis was confirmed by the morphometric cellular edema index and the volume-to-surface ratio of the mitochondria. Myocardial oxygen consumption was highest and lactate production was lowest in senescent hearts. CONCLUSION Senescent rat hearts were more susceptible to unprotected ischemia/reperfusion injury than young adult hearts. When protected by BCP, we found no difference in hemodynamic performance between adult and senescent hearts indicating preserved myocardial protection even in senescent individuals.

Abstract
BACKGROUND AND PURPOSE It is important for patients recovering from coronary artery bypass (CAB) surgery to initiate and maintain recommended exercise guidelines. The purpose of this qualitative study was to describe factors that influence adherence to exercise, and perceptions of activity limitations and health-related quality of life (QoL) in older patients recovering from CAB surgery. SUBJECTS Participants were 28 people aged 65 and older, prospectively recruited from a U.S. hospital following CAB surgery. PROCEDURES A qualitative description methodology was used to identify factors that influenced participants' feelings about exercise and QoL. Data were collected using phone interviews 3, 6, and 12 months after surgery. Data were coded by identifying significant statements, grouping them into meaningful units or "themes", and generating descriptions of participants' experiences and understandings. RESULTS Across time points, participants' most commonly described motivators were that it feels good to exercise, and belief that it improves physical health. The most commonly cited barriers to exercise were other time commitments, inclement weather, and pain/injury/illness related or unrelated to CAB surgery. DISCUSSION AND CONCLUSION Motivating themes remained consistent across the time intervals but the number of responses regarding barriers to exercise increased over time. A better understanding of the patient experience may help to promote exercise initiation and adherence following CAB surgery.

Abstract
Objective Octogenarians (aged ≥ 80 years) are increasingly being referred for cardiac surgery. We aimed to describe the morbidity, mortality, and health services utilization of octogenarians undergoing elective cardiac surgery. Methods Retrospective population-based cohort study of adult patients receiving elective cardiac surgery between January 1 2004 and December 31 2009. Primary exposure was age ≥80 years. Outcomes were 30-day, 1- and 5-year mortality, post-operative complications, and ICU/hospital lengths of stay. Multi-variable logistic and Cox regression analyses were used to explore the association between older age and outcome. Results Of 6,843 patients receiving cardiac surgery, 544 (7.9%) were octogenarians. There was an increasing trend in the proportion of octogenarians undergoing surgery during the study period (0.3% per year, P = 0.073). Octogenarians were more likely to have combined procedures (valve plus coronary artery bypass or multiple valves) compared with younger strata (p < 0.001). Crude 30-day, 1-year and 5-year mortality for octogenarians were 3.7%, 10.8% and 29.0%, respectively. Compared to younger strata, octogenarians had higher adjusted 30-day (OR 4.83, 95%CI 1.30-17.92; P = 0.018) and 1-year mortality (OR 4.92; 95% CI, 2.32-10.46. P<0.001). Post-operative complications were more likely among octogenarians. Octogenarians had longer post-operative stays in ICU and hospital, and higher rates of ICU readmission (P < 0.001 for all). After multi-variable adjustment, age ≧ 80 years was an independent predictor of death at 30-days and 1 year. Conclusions Octogenarians are increasingly referred for elective cardiac surgery with more combined procedures. Compared to younger patients, octogenarians have a higher risk of post-operative complications, consume greater resources, and have worse but acceptable short and long-term survival.

Abstract
PURPOSE Health-related quality of life (HRQoL) measured on the EQ-5D (European quality of life-5 dimensions)-questionnaire has been shown to improve after coronary artery bypass grafting (CABG), this study investigated whether changes in HRQoL predict later morbidity. METHODS Included were 404 consecutive patients undergoing isolated CABG between 2008 and 2010 who filled the EQ-5D-questionnaire at baseline and 6 months postoperatively. Records were reviewed for later major adverse cardiac and cerebrovascular events (MACCE) after 6 months. Follow-up was 38.6 months (10-58). RESULTS Patients who suffered later MACCE more often had suffered an in-hospital postoperative stroke, had a longer in-hospital stay, had lower HRQoL scores at 6 months and deteriorated on several EQ-5D-subscales. Logistic regression showed 6 months visual analogue scale scores and declining function scores to be independent predictors of later MACCE. CONCLUSION Deteriorating function and HRQoL-scores at 6 months as compared to baseline postoperatively predict later adverse cardiovascular events after CABG.

Abstract
BACKGROUND Advances in cardiac surgical care have allowed for successful surgery in high-risk elderly patients. Advances in percutaneous coronary intervention (PCI) techniques and expanded indications for PCI have resulted in a decrease in referrals for coronary artery bypass grafting (CABG). Our objective was to document changes in practice patterns and outcomes in a single tertiary cardiac surgery centre serving a large geographic area. METHODS For all cardiac surgery cases performed from 2001-2010 we examined its use, patient clinical characteristics, and outcomes. Frailty was assessed using a measure we have previously demonstrated to be associated with adverse outcomes. RESULTS During the study period, annual case volume decreased by 13%. The number of isolated CABG cases declined, and valve surgery and other complex procedures increased. The proportion of patients aged ≥ 80 years rose from 7%-12%, and the proportion of frail patients increased from 4%-10%. Although unadjusted in-hospital mortality remained relatively unchanged, intensive care unit (ICU) stays and prolonged institutional care increased. Older age and frailty were associated with mortality, prolonged ICU stays, prolonged institutional care, and a composite of mortality and major morbidities. CONCLUSIONS Our findings showed a decline in CABG, an increase in more complex operations, and an increase in prolonged ICU stays and prolonged institutional care. The proportion of frail and elderly patients increased over time and these patient groups were at higher risk of adverse postoperative outcomes. Particular attention is required in the decision for surgery and perioperative management of these patients.
