Abstract
BACKGROUND The hospital mortality rate in >80-year-old patients undergoing surgical aortic valve replacement (SAVR) is reportedly satisfactory, but how such patients' functional status both at discharge and during the postoperative hospitalization period might affect their quality of life and medical costs remains unclear.Methods and Results:The adverse events of 161 patients aged >80 years who underwent SAVR with or without coronary artery bypass grafting were retrospectively investigated. Adverse events were defined as hospital death, a long hospital stay (>60 days) attributable to major complications or requirement for rehabilitation, or a depressed status at discharge (modified Rankin scale score >4). A total of 18.6% of patients developed adverse events, and their hospital mortality rate was 4.3%. Logistic regression analysis revealed that a perfusion time >3 h (P=0.0331; odds ratio, 2.685) and EuroSCORE II >10% (P<0.0001; odds ratio, 8.232) were significant risk factors for adverse events. The average medical cost was approximately 1.5-fold higher in patients with adverse events (¥8,360,880 vs. ¥5,234,660, P=0.0016). CONCLUSIONS Clinical findings focusing on status at discharge and during postoperative hospitalization of SAVR in patients aged >80 years was relatively high compared with hospital mortality, especially in patients with a longer perfusion time and high EuroSCORE. Further studies are necessary to define the indications for SAVR in patients aged >80 years in the era of transcatheter AVR.

Abstract
PURPOSE Cardiac surgery in octogenarians with severely deteriorated functional status is increasingly common, but outcome data are still limited. The aim of this study was to compare postoperative outcome, survival, and quality of life of low-, medium-, and high-risk octogenarians undergoing cardiac surgery. METHODS In all, 285 Czech octogenarians who underwent any cardiac surgical procedure between January 2011 and December 2012 were included in the study. Five out of all twelve national adult cardiac surgical centers participated in the study, representing almost half of all octogenarians operated in our country in that period. Patients' perioperative data were analyzed retrospectively. Follow-up was performed by interviewing patients by telephone. RESULTS There was higher 30-day mortality (20% vs. 6.4% vs. 5.2%, respectively, p <0.001), lower 2-year survival (60% vs. 84.0% vs. 85.4%, respectively, p <0.05), and lower Karnofsky score (44.4 vs. 70.1 vs. 70.6, respectively, p <0.001) in high-risk group compared with medium- and low-risk groups, respectively. Greater improvement in New York Heart Association (NYHA) status was noted in high- and medium-risk groups compared with low-risk group (51% vs. 45% vs. 24%, respectively, p <0.05). CONCLUSION High perioperative mortality, poor 2-year survival, and low postoperative quality of life have been observed in high-risk octogenarians undergoing cardiac surgery.

Abstract
OBJECTIVES Current outcome measures in cardiac surgery are largely described in terms of mortality. Given the changing demographic profiles and increasingly aged populations referred for cardiac surgery this may not be the most appropriate measure. Postoperative quality of life is an outcome of importance to all ages, but perhaps particularly so for those whose absolute life expectancy is limited by virtue of age. We undertook a systematic review of the literature to clarify and summarise the existing evidence regarding postoperative quality of life of older people following cardiac surgery. For the purpose of this review we defined our population as people aged 80 years of age or over. METHODS A systematic review of MEDLINE, EMBASE, Cochrane Library, trial registers and conference abstracts was undertaken to identify studies addressing quality of life following cardiac surgery in patients 80 or over. RESULTS Forty-four studies were identified that addressed this topic, of these nine were prospective therefore overall conclusions are drawn from largely retrospective observational studies. No randomised controlled data were identified. CONCLUSIONS Overall there appears to be an improvement in quality of life in the majority of elderly patients following cardiac surgery, however there was a minority in whom quality of life declined (8-19%). There is an urgent need to validate these data and if correct to develop a robust prediction tool to identify these patients before surgery. Such a tool could guide informed consent, policy development and resource allocation.

Abstract
BACKGROUND The proportion of elderly (≥80 years) patients undergoing coronary artery bypass surgery (CABG) is increasing. METHODS A retrospective analysis of data, collected by the Australasian Society of Cardiac and Thoracic Surgeons Cardiac Surgery Database Program between June 2001 and December 2009 was performed. Isolated CABG was performed in 21,534 patients; of these, 1,664 (7.7%) were at least 80 years old (group 1). Patient characteristics, morbidity, and short-term mortality of these patients were compared with those aged less than 80 years (group 2). The long-term outcome of group 1 patients after CABG surgery was compared with an age and sex-matched Australian population. RESULTS Patients over 80 years old were more likely to be female (36.6% vs 17.3%, p < 0.001) and presented significantly more often with heart failure, hypertension, and triple-vessel disease (all p < 0.05). The 30-day mortality was higher in group 1 patients (4.2% vs 1.5%, p < 0.001). Group 1 patients also had an increased risk of complications, including prolonged (>24 hours) ventilation (14.2% vs 8.2%, p < 0.001), renal failure (7.3% vs 3.4%, p < 0.001), and mean intensive care unit stay (60.7 vs 42.5 hours, p < 0.001). The 5-year survival of elderly patients (73%) was comparable with the age-matched Australian population. Independent risk factors for 30-day mortality in group 1 patients included preoperative renal failure (p = 0.010), congestive heart failure (p = 0.014), and a nonelective procedure (p = 0.016). CONCLUSIONS Elderly patients who undergo isolated CABG have significantly lower perioperative risks than have been previously reported. The long-term survival of these patients is comparable with an age-adjusted population.

Abstract
The results of on-pump coronary artery bypass graft (CABG) surgery in 166 high-risk elderly patients (EuroSCORE 6 or more; over age 65 years [mean 71.8 years]) were compared with 176 low-risk elderly patients (EuroSCORE below 6; over age 65 years [mean 68.8 years]). There was no significant difference in hospital mortality or number of grafts between the two groups. Rates of inotropic agent use, intra-aortic balloon pump insertion and atrial fibrillation, and the duration of intensive care unit and hospital stay were significantly higher in high-risk than low-risk patients. There were no significant differences in the incidence of major complications between the two groups. The results suggest that, in selected patients, on-pump CABG can be safely performed in high-risk patients over 65 years old with no effect on mortality.

Abstract
Background To evaluate the impact and safety of different surgical techniques for aortic root replacement (ARR) on early and late morbidity and mortality in septuagenarians undergoing ARR. Methods Ninety-five patients (73.8 ± 3.2 years) were operated and divided into three groups according to the aortic root procedure; MECH-group (n = 51) patients with a mechanical composite graft, BIO-group (n = 22) patients with a customized biological composite graft, and REIMPL-group (n = 22) patients with a valve sparing aortic root reimplantation (David I). In 42.1% (40/95) of these patients the aortic arch was replaced. Follow-up was completed in 95.2% (79/83) of in-hospital survivors. Results Hospital mortality was 12.6% (12/95) in the entire population (MECH. 15.7% (8/51), BIO 19.7% (4/22), REIMPL 0% (0/22); p = 0.004). Two patients died intraoperatively. The most frequent postoperative complications were prolonged mechanical ventilation ((>48 h) in 16.8% (16/93) (MECH. 7% (7/51), BIO 36.4% (8/22), REIMPL 4.5% (1/22); p = 0.013) and rethoracotomy for postoperative bleeding in 12.6% (12/95) (MECH. 12% (6/51), BIO 22.7% (5/22), REIMPL 4.5% (1/22); p = 0.19). Nineteen late deaths (22.9%) (19/83) (MECH 34.8% (15/43), BIO 16.7% (3/18), REIMPL 4.5% (1/22); p = 0.012) occurred during a mean follow-up of 41 ± 42 months (MECH 48 ± 48 months, BIO 25 ± 37 months, REIMPL 40 ± 28 months, p = 0.028). Postoperative NYHA class decreased significantly (p = 0.017) and performance status (p = 0.027) increased for the entire group compared to preoperative values. Conclusion Our data indicate that valve sparing aortic root reimplantation is safe and effective in septuagenarians, and is associated with low early and late morbidity and mortality.

Abstract
Instruments with acceptable measurement properties that support their application to older adults across a range of settings need to be identified. A narrative literature review of empirical studies investigating the conceptualization and measurement of quality of life (QoL) among older adults from 1994 to 2006 was performed. The review focused on evidence provided for conceptual frameworks, QoL definitions, types of measurements utilized and their psychometric properties. Two searches were conducted. The first search conducted in 2004 used Cinahl, Medline, PsycInfo, Embase and Cochrane databases. A supplemental search was conducted in December 2006, which included these bases from 2004 to 2006, and Sociological Abstracts and Anthropological literature base. The review included 47 papers. A total of 40 different measurements were applied in the studies, assessing most frequently functional status and symptoms. The most extensive psychometric evidence was documented for the SF-36. Although construct validity was reported in the majority of studies, minimal empirical evidence was given for other psychometric properties. Further, 87% of the studies lacked a conceptual framework and 55% did not report any methodological considerations related to older adults. Quality control standards, which can guide measurement assessment and subsequent data interpretation, are needed to enhance more consistent reporting of the psychometric properties of QoL instruments utilized. Future work on the development of common QoL assessment models that are both person-centered, causal and multidimensional based on collaborative efforts from professionals interested in QoL from the international gerontological research community are needed.

Abstract
BACKGROUND Global population aging and greater age-related incidence of ischemic, degenerative and calcific valve disease have led to an increasing number of very elderly patients being referred for valve surgery. However, their preoperative risk factors, and in-hospital and long-term outcomes have not been thoroughly investigated. METHODS Three hundred seven consecutive patients 80 years and older (60% female; mean age 83+/-2.4 years) attending three major Italian cardiac centres to undergo valve surgery were evaluated. Seventy-nine patients underwent mitral valve surgery (isolated n=30, combined n=49) and 228 underwent aortic valve surgery (isolated n=134, combined n=94). RESULTS The most frequent in-hospital complications were atrial arrhythmias, need for inotropic support for more than 48 h, renal insufficiency, congestive heart failure, respiratory failure, and stroke or transient ischemic attack. The in-hospital mortality rate was 9.7% (30 of 307). Multivariate logistic regression identified the following clinical variables as predictors of in-hospital death: New York Heart Association functional class IV, diabetes, hypertension, renal insufficiency at presentation, rheumatic etiology and left ventricular ejection fraction of less than 45%. Late mortality occurred in 45 of 277 patients (16.2%), but there was a substantial improvement in the New York Heart Association functional class of the 232 long-term survivors (from 3.0+/-0.7 to 1.7+/-0.6; P<0.0001). CONCLUSIONS Surgery seems to be an effective therapeutic option for selected symptomatic octogenarians with valve disease, associated with good long-term survival and an improved functional class. Operative mortality is related more to patients' preoperative clinical status and increased comorbidity than the type of surgery per se.

Abstract
OBJECTIVE To describe and compare the crude and risk-adjusted survival of a series of octogenarians with symptomatic severe aortic stenosis (SAS) or severe coronary artery disease (SCAD). METHODS We reviewed the treatment and outcomes of 130 consecutive patients > or = 80 years old hospitalized for SAS or SCAD. RESULTS Mean age was 82.8+/-3.1 years, 52% were women. Of 83 patients with SCAD, 52 were treated by coronary stenting (63%), 12 by coronary artery bypass grafting (15%) and 19 medically (23%). There were no significant differences in baseline characteristics among different treatment groups. When comparing the medically treated group with the intervention group (coronary artery bypass grafting or stenting), the former showed a trend to a worse prognosis (adjusted HR 2.5, 95% CI 0.98-6.6, p=0.056). Of 47 patients treated with SAS, 33 were treated surgically (70%), 26 by aortic valve replacement (AVR) alone and 7 combined with coronary revascularization. Fourteen patients were treated medically (30%). Patients treated with AVR were younger, presented less frequently a previous MI and had better left ventricular systolic function. Multivariate analysis did not find AVR associated to a better survival (HR 1.1, 95% CI 0.2-5.4). CONCLUSION Cardiac surgery in octogenarians is more frequently performed in patients with SAS than in patients with SCAD, but survival benefit is probably greater in the latter. A more conservative approach with medical therapy in patients with SAS and coronary stenting in patients with SCAD are alternatives that should be considered.

Abstract
To evaluate and compare the outcome of open-heart surgery in elderly patients with a concurrent group of younger patients in a developing country, data of all adult patients who underwent open-heart surgery during the period of 3 years from January 1999 to December 2001 were collected prospectively. Demographic data such as age and gender, other data such as preoperative diagnoses, comorbid illnesses, type of surgery, time of cardio-pulmonary bypass, length of stay and hospital outcome were recorded. The characteristics of patients above the age of 65 years were compared with a concurrent cohort of patients aged less than 65 years. One hundred and forty-five adult patients underwent open-heart surgeries in 3 years, and the overall mortality rate was 4.8%. The much common surgeries were coronary artery bypass grafting, valve repair/replacement surgery and surgery for adult congenital heart diseases. Forty-five (31%) patients were above the age of 65 years. The mortality rate was 2.2% for patients who were aged 65 years and above, in comparison with that of the concurrent cohort of younger patients (6%). This was probably because of more number of surgeries for congenital heart diseases in the latter group. However, even with other surgeries such as coronary artery bypass grafting, the elderly group of patients did equally well as the younger group. Elderly patients tolerate cardiac surgery well, and age should not be an exclusive criterion to decide against open-heart surgery.

Abstract
Background—
Prosthesis–patient size mismatch results when an implanted prosthetic aortic valve is of insufficient size for a patient’s body surface area. The relation between prosthesis–patient size and functional capacity and adverse postoperative outcome is inconsistent. Our objectives were to examine the impact of valve replacement, continuous prosthesis–patient size, and other factors on functional recovery after aortic valve replacement (AVR) with the Duke Activity Status Index (DASI).
Methods and Results—
From June 15, 1995, through May 14, 1998, 1108 patients underwent AVR after completing a DASI survey. Of these, 1014 completed a postoperative DASI survey at an average of 8.3 months postoperatively. Logistic ordinal regression was used to examine the influence of demographic variables, comorbidities, baseline DASI scores, indexed valve orifice area, standardized orifice size, and postoperative morbid events on postoperative DASI. There was overall improvement in postoperative functional recovery reflected by median preoperative and postoperative DASI scores of 29 and 46,
P
<0.001, respectively. Neither indexed orifice area,
P
=0.94, nor standardized orifice size,
P
=0.96, was associated with functional recovery. Female sex, increasing age, elevated serum creatinine, increased central venous pressure, and red blood cell transfusion were factors associated with poor postoperative functional recovery.
Conclusions—
A majority of patients report improvement in functional quality of life early after AVR. Similar functional recovery was demonstrated for patients along the full spectrum of valve sizes indexed to body size, even for values considered to represent severe mismatch for patient size. Factors other than prosthesis–patient size influence functional quality of life early after AVR.

Abstract
BACKGROUND Cardiac surgery is being performed with increasing frequency in octogenarians. The purpose of the present study was to determine the outcome and quality of life of octogenarians after cardiac surgery in a single surgeon series and in a newly established cardiac surgery unit. METHODS Prospective data collection and analysis were undertaken of octogenarians having cardiac surgery from 1997 to 2003 by a single surgeon in a single institution. The outcome was compared to septuagenarians operated on by the same surgeon in the same time frame, specifically to see if there were any significant differences in outcomes between these two close age groups. Follow up was conducted by sending a questionnaire, interviewing patients or their general practitioner. RESULTS There were significantly less octogenarians with airway disease but more with class III and IV New York Heart Association heart failure. There were no significant differences in the incidence of left main disease, urgent operations, renal impairment and cerebrovascular disease between the two groups. There was a trend towards increased operative mortality in octogenarians when the group was taken as a whole (8%vs 2%, P = 0.052). They also had a significantly higher incidence of respiratory failure (6%vs 2%, P = 0.029). The incidence of stroke, renal failure and low cardiac output was not significantly different between the two groups. Blood product usage was significantly higher in octogenarians (19%vs 9%, P = 0.042), but re-operation for bleeding was not significantly different (3%vs 4%). Intensive care unit median length of stay was significantly longer in the case of Octogenarians (1.0 vs 0.9 days, P = 0.039), but the duration of hospital stay was similar (6.5 vs 6.4 days, P = 0.165). Follow up was 94.5% complete, 85% of the octogenarians responded to the questionnaire sent to them. All patients were free of angina, 98% of them had improved by at least one New York Heart Association heart failure class and 86.7% felt that they were less dependent on others after cardiac surgery. In retrospect, 94.2% said that they would have the procedure again. CONCLUSION Octogenarians can be operated on with acceptable mortality and morbidity to achieve significant improvement in quality of life. The outcome of surgery in these patients in a new unit is comparable with established units.

Abstract
This prospective study was instituted to assess whether the use of the on-pump method or the off-pump method affects changes in health-related quality of life (QOL) as evaluated a year after coronary artery bypass graft (CABG) surgery. Data including preoperative risk factors and postoperative morbidity up to discharge were collected from 508 CABG patients operated in the Heart Center of a university hospital and further treated in secondary referral hospitals. Four hundred and fifty-two (89.0%) patients underwent operation with the on-pump method and 56 (11.0%) with the off-pump method, i.e., without cardiopulmonary bypass (CPB). The RAND-36 Health Survey (RAND-36) was used as indicator of QOL. The primary outcome measure was a change in the physical component summary (PCS) and mental component summary (MCS) from the RAND-36. Symptomatic status was estimated according to New York Heart Association (NYHA) class. Assessments were made preoperatively and repeated 12 months later. The majority of patients operated on-pump (85.6%) and off-pump (92.9%) had a favorable outcome without major complications (p = 0.136). The present data showed significant improvement (p < 0.001) in all eight domains of QOL following on-pump CABG. Likewise, off-pump patients improved in all eight aspects, and the change was statistically significant in six dimensions. A highly significant (p < 0.001) pattern of change was seen in the RAND-36 MCS and PCS scores in both operative groups. Differences between the groups were nonsignificant. We conclude that most patients experience significant improvement in health-related QOL during the first year after CABG, and that cardiopulmonary bypass has no effect on patients' subsequent health-related QOL, but its use depends on specific indications.

Abstract
Several recent studies have highlighted the potential benefits of using off-pump coronary artery bypass (OPCAB) surgery, particularly in high-risk patients. The aim of this meta-analysis is to assess the effect of OPCAB on the incidence of stroke compared with coronary artery bypass grafting using cardiopulmonary bypass (CPB) in elderly patients. We performed a meta-analysis of all observational studies, published in MEDLINE between 1999 and 2002 and a comparison between the OPCAB and CPB techniques in elderly patients was performed with the outcome of interest being the incidence of stroke. Elderly patients were defined as those aged 70 years or older. Nine studies are included in the meta-analysis. The total number of subjects included was 4,475 patients, of which, 1,253 underwent OPCAB (28%) and 3,222 (72%) underwent CPB. The meta-analysis showed that the OPCAB technique was associated with significantly lower incidence of stroke in elderly patients compared with the CPB technique (1% vs 3%), with an odds ratio of 0.38% to 95% (CI, 0.22 to 0.65). We did not identify any significant heterogeneity and funnel plot asymmetry between the studies included in the meta-analysis. Meta-regression analysis including variables predicting stroke, mortality, and study characteristics did not show any associations affecting the calculated odds ratio of stroke. Despite the fact that this is a meta-analysis of observational studies and adjustment for differences in baseline risk factors between OPCAB and CPB patients was not possible, we believe that this study suggests that the OPCAB technique might be associated with reduced incidence of stroke in the elderly patients undergoing coronary artery bypass grafting.

Abstract
BACKGROUND Cardiac surgery is frequently performed to palliate cardiovascular symptoms in patients who are octogenarians, without controlled clinical trials to support its benefits. We hypothesized that death or discharge to a nursing care facility after cardiac surgery is similar in patients who are octogenarians and younger patients. METHODS We conducted an inception cohort study in a tertiary care teaching hospital in patients who had undergone coronary grafting, valve surgery, or both over 36 months before. We collected data on preoperative disease, operation characteristics, postoperative complications, and outcome at hospital discharge. RESULTS Of 783 patients who had cardiac surgery, 96 were octogenarians. Female sex, pulmonary hypertension, previous malignancy, cerebral vascular disease, valvular heart disease, and congestive heart failure were more frequent in patients who were octogenarians than in younger patients. Operative characteristics were similar in both age groups, except there were more frequent valve or combined with coronary grafts surgery and surgical re-exploration in octogenarians. The rate of postoperative complications including cardiovascular, neurological, renal, and nosocomial infections were higher in patients who were octogenarians than younger patients. Death or discharge to a nursing care facility was more frequent in patients who were octogenarians than younger patients (53% vs 14%, P <.002). Age > or =80 years, female sex, congestive heart failure, and surgical re-exploration were independent predictors for death or discharge to a nursing care facility after cardiac surgery. CONCLUSIONS The rate of death or discharge to nursing care facility after cardiac surgery was high among patients who were octogenarians. Current operative outcome end points do not reflect such important differences between patients who are octogenarians and younger patients. Informed discussion of treatment options, potential for discharge to a nursing care facility, and quality of life expectations should precede a decision to undergo cardiac surgery in patients who are octogenarians. Randomized clinical trials of medical versus surgical palliation of cardiovascular symptoms in patients who are octogenarians are needed to justify cost-effectiveness and guide better use of relatively scarce Medicare resources.

Abstract
OBJECTIVES Off-pump coronary artery bypass grafting (CABG) has become accepted for myocardial revascularization because it reduces perioperative morbidity. We assessed the safety and efficacy of bypass surgery on the beating heart in elderly patients. METHODS Off-pump CABG was done in 25 patients aged 80 years or older between February 1996 and February 2001. We retrospectively compared clinical results for these patients to those of 18 consecutive age-matched patients undergoing on-pump CABG during the same period. RESULTS Mean patient age in both groups was similar--82.2 +/- 2.3 years in the off-pump group vs 81.9 +/- 2.0 years in the on-pump group (p = 0.66). Preoperative risk was similar in both groups, but significantly more patients in the on-pump group had triple-vessel disease. Distal anastomoses were significantly fewer in the off-pump group than in the on-pump group at 2.0 +/- 1.0 vs 2.8 +/- 0.5 (p < 0.01). The off-pump group had a shorter postoperative ventilation--13.4 +/- 17.2 hours vs 45.2 +/- 52.8 hours (p < 0.05)--, and less blood transfused--16% vs 89% (p < 0.01)--than the on-pump group. Mean postoperative hospitalization and intensive care unit stay were 18.6 days and 3.2 days in the off-pump group, versus 37.1 days and 9.4 days in the on-pump group (p < 0.05). No difference was seen in the incidence of major postoperative complications between groups. No hospital deaths occurred in the off-pump group. CONCLUSION Off-pump CABG is thus a safe and effective for myocardial revascularization in the elderly.

Abstract
OBJECTIVE We studied disease and surgical outcomes in an 80-plus age group to determine the feasibility of cardiac surgery at this age. METHODS Between January 1991 and August 2000, we statistically analyzed 19 variables in 62 consecutive cases of cardiac surgery in the 80-plus age group to predict in-hospital and long-term mortality. Cases were classified by disease type (ischemic heart disease (IHD), n = 39; valvular heart disease (VHD) n = 19; and mechanical complications associated with acute myocardial infarction, n = 4; and by surgical status (emergency, n = 6; urgent, n = 10; and elective, n = 46). We compared these with 370 patients 70 to 79 years undergoing similar procedures during the same interval. RESULTS No significant difference was seen between groups in total in-hospital mortality--9.7% vs. 3.8%--or in-hospital mortality for IHD--2.6% vs. 4.2%--or VHD--10.5% vs. 2.8%. We found cardiopulmonary bypass time > 150 min. and dialysis to be independent risk factors for hospital death. Actuarial survival at 7.5 years overall was 39% in the 80-plus age group vs. 53% in the 70-79 age group for VHD and 38% in the 80-plus age group vs. 62% in the 70-79 age group. No significant difference was seen in survival between groups for IHD. Stroke proved to be an independent prognostic factor. CONCLUSIONS Cardiac surgery is conducted feasibly in selected octogenarians, providing acceptable mortality and results similar to those achieved in those 70 to 79 years old.

Abstract
The management of cardiopulmonary bypass has evolved over the last 50 years resulting in a largely consistent approach to both adult and pediatric perfusion. Very little has been written or prospectively researched on the best practice for cardiopulmonary bypass in the high-risk elderly patient, despite the challenge this patient cohort presents compared to the general adult population and the rapidly increasing number of such patients undergoing cardiac surgery. We propose a framework for perfusion strategies for the high-risk elderly patient from our current understanding of cardiopulmonary bypass. It should stimulate discussion for a consensus on perfusion strategies for the elderly and encourage further research into perfusion variables as they relate to the outcome of patients of advanced age.

Abstract
STUDY OBJECTIVES To evaluate cost, outcome, and functional status of octogenarians and septuagenarians after cardiac surgery. DESIGN Observational case control study. Retrospective analysis of hospital cost and outcome. Prospective analysis of functional status at 1 to 2 years. PATIENTS One hundred three consecutive octogenarians and 103 randomly selected septuagenarians who underwent cardiac surgery. SETTING A university-affiliated tertiary care center. MEASUREMENTS AND RESULTS Compared to septuagenarians, octogenarians were more likely to be widowed (p < or = 0.001) and to have had preoperative strokes (p < or = 0.05) but were less likely to have diabetes mellitus (p < or = 0.001). They were less likely to have undergone mitral valve surgery (p < or = 0.01) but were more likely to have undergone coronary artery bypass graft surgery without cardiopulmonary bypass (p < or = 0.001). The hospital mortality rate was 6% in the younger group and 9% in the older group (odds ratio, 1.5; 95% confidence interval [CI], 0.5 to 4.5; p > 0.05). In patients undergoing isolated CABG, the mortality rate was 1.4% in the septuagenarians and 8.2% in the octogenarians (odds ratio, 6.2; 95% CI, 0.7 to 52.7; p = 0.12). Despite similar ICU, postoperative, and total lengths of stay, the median hospital direct variable cost was 35% higher for the octogenarians. At late follow-up, octogenarians had lower levels of physical functioning and general health but otherwise had levels of function that were similar to those of septuagenarians. CONCLUSION Cardiac surgery can be performed in the elderly with good hospital and late functional results, but at a higher hospital cost than that for younger patients.

Abstract
EXECUTIVE SUMMARY: Most randomized, controlled trials evaluating the effectiveness of pharmaceutical, surgical, and device interventions for the prevention and treatment of cardiovascular disease have excluded patients over 75 years of age. Consequently, the use of these therapies in the older population is based on extrapolation of safety and effectiveness data obtained from younger patients. However, there are many registries and observational databases that contain large amounts of data on patients 75 years of age and older, as well as on younger patients. Although conclusions from such data are limited, it is possible to define the characteristics of patients who did well and those who did poorly. The goal of this conference was to convene the principal investigators of these databases, and others in the field of geriatric cardiology, to address questions relating to the safety and effectiveness of treatment interventions for several cardiovascular conditions in the elderly. Seven committees discussed the following topics: (I) Risk Factor Modification in the Elderly; (II) Chronic Heart Failure; (III) Chronic Coronary Artery Disease: Role of Revascularization; (IV) Acute Myocardial Infarction; (V) Valve Surgery in the Elderly; (VI) Electrophysiology, Pacemaker, and Automatic Internal Cardioverter Defibrillators Databases; (VII) Carotid Endarterectomy in the Elderly. The chairs of these committees were asked to invite principal investigators of key databases in each of these areas to discuss and prepare a written statement concerning the available safety and efficacy data regarding interventions for these conditions and to identify and prioritize areas for future study. The ultimate goal is to stimulate further collaborative outcomes research in the elderly so as to place the treatment of cardiovascular disease on a more scientific basis.

Abstract
Cardiac surgery among older people is becoming commonplace in Australia. However, there is little evidence that critical care nursing management has addressed the unique needs of this patient population during the postoperative recovery stage. Their specific physiologic and psychological differences identify them as having particular needs in regard to nursing care. For many years, cardiac patients were carefully screened and only those who had reduced risk factors were considered for surgery. Now there are increasing referrals of older patients with a range of conditions and increased risk factors. These people present with more difficult surgical problems and tend to have a complicated postoperative period. As a result they are proving to be a clinical management challenge. In light of the evidence presented, clear examination of the unique needs of the very elderly during the immediate postoperative phase is suggested to provide the basis for a comprehensive overhaul of patient management with positive implications for standards of care.

Abstract
BACKGROUND Coronary artery bypass grafting in patients over 75 years is associated with high operative risk. Target vessel revascularization without cardiopulmonary bypass is a promising option for highly selected, older patients. However, the outcome remains uncertain. METHODS We investigated 44 patients over 75 years, matched for preoperative risk and left ventricular function, who underwent coronary artery bypass grafting either with or without cardiopulmonary bypass (CPB). We analyzed patients characteristics, Parsonnet score, EuroSCORE, short as well as midterm outcome and quality of life (freedom from recurrence of angina, anti-anginal therapy, sf36 test). RESULTS Perioperative mortality was higher in the patient group operated with CPB (15.9) as compared to patients operated without CPB (4.5%, p = 0.0226). Patients operated with cardiopulmonary bypass received more grafts (3.1 +/- 0.1) than patients operated without cardiopulmonary bypass (1.6 +/- 0.1, p = 0.0001) and and were more likely to undergo complete revascularization (with CPB 100%, without CPB 63.6%, p = 0.0010). Perioperative complications were more frequent and midterm survival was worse in the patient group operated with CPB (log rank p = 0.0228). Quality of life was comparable in both groups. CONCLUSIONS The concept of incomplete target vessel revascularization of the culprit lesion seems to be a promising option for selected high-risk patients, predominantly due to lower perioperative mortality.

Abstract
OBJECTIVE Aging of the population is a current phenomenon in Japan, and life expectancy at 80 years old is getting longer. So we reviewed cardio-aortic operations on octogenarians at our institution. SUBJECTS AND METHODS Thirty-three consecutive octogenarian patients who had undergone cardio-aortic operations from 1992 to 1998 were studied. There were 14 men and 19 women. The mean age was 81.9 years. Of the 33, 19 patients (58%) were in New York Heart Association class IV, and 21 patients (64%) were operated on urgently or in emergency. The procedures undergone were operation for coronary artery disease in 17 patients, operation for valvular disease in 7 patients, operation for thoracic-aorta in 7 patients, and others in 2 patients. RESULTS The hospital mortality rate was 27% (9 patients). However, 89% of patients experiencing hospital death were in New York Heart Association class IV preoperatively and had required an emergency/urgent operation. On the other hand, there was only one hospital death (1/12, 8.3%) among the elective patients. The statistically significant risk factors for hospital death were renal insufficiency, shock, New York Heart Association class IV, intra-aortic balloon pumping, and longer cardiopulmonary bypass time. The one-, three-, and five-year-survival rate was 73%, 68%, and 55%, respectively. Of the survivors, 77% were in class I or II. CONCLUSION Although octogenarians' hospital mortality was still very high, the mid-term results were acceptable and the survivors' quality of life was satisfactory. These data suggested that we should operate on cardio-aortic patients before they reach a very serious state, especially in octogenarians.

BACKGROUND The proportion of patients in their ninth decade of life undergoing complex cardiovascular procedures has increased over the past decade. The purpose of this study is to quantify the potential for stroke and mortality associated with deep hypothermic circulatory arrest (DHCA) in this age group. METHODS At our institution, 251 adult patients had cardiovascular procedures that required DHCA since 1989. This included 20 patients 80 years of age or older (group I) and 231 patients less than 80 years (group II). Additionally, we analyzed 632 patients 80 years of age or older who underwent a variety of cardiovascular procedures since 1989 that required cardiopulmonary bypass but not DHCA (group III). Neurologic outcomes have been maintained in our database prospectively since 1991. RESULTS The 30-day mortality in group I was 5%, in group II 15.2%, and in group III 8.2%. The stroke rate was 20% in group I, 8.8% in group II, and 6.5% in group III. CONCLUSIONS DHCA can be performed with acceptable early mortality in patients in their ninth decade of life, but they are at an increased risk of stroke. Follow-up shows satisfactory late survival.

Abstract
BACKGROUND Increasing numbers of the very old are presenting for cardiac surgical procedures. There is little information about quality of life after hospital discharge in this group. METHODS From March 1995 to February 1997, 127 patients older than 80 years at operation (mean age, 83+/-2.5 years; range, 80 to 92 years) were entered into the cardiac surgery database and analyzed retrospectively. The RAND SF-36 Health Survey and the Seattle Angina Questionnaire were used to assess quality of life by telephone interview (mean follow-up, 15.7+/-6.9 months). No patient was lost to follow-up. RESULTS Operations included coronary artery bypass grafting (65.4%), coronary artery bypass grafting plus valve replacement (15.8%), and isolated valve replacement (14.2%). Preoperatively, 63.8% were in New York Heart Association class IV. Thirty-day mortality was 7.9%, and actuarial survival was 83% (70% confidence interval, 79% to 87%) at 1 year and 80% (70% confidence interval, 75% to 85%) at 2 years. Preoperative renal failure significantly increased the risk of early death (relative risk, 3.96) as did urgent or emergent operation (relative risk, 6.70). In addition, cerebrovascular disease (relative risk, 3.54) and prolonged ventilation (relative risk, 3.82) were risk factors for late death. Ninety-five patients (92.2%) were in New York Heart Association class I or II at follow-up. Seattle Angina Questionnaire scores for anginal frequency (92.3+/-18.9), stability (94.4+/-16.5), and exertional capacity (86.8+/-25.1) indicated good relief of symptoms. SF-36 scores were equal to or better than those for the general population of age greater than 65 years. Of the survivors, 83.7% were living in their own home, 74.8% rated their health as good or excellent, and 82.5% would undergo operation again in retrospect. CONCLUSION Octogenarians can undergo cardiac surgical procedures at a reasonable risk and show remarkable improvement in their symptoms. Elderly patients benefit from improved functional status and quality of life.

Abstract
BACKGROUND Due to improved operative techniques, myocardial preservation, and perioperative care, open heart procedures are now being performed in older and sicker patients. As a result, the quality of life has become an important issue in the decision making process. METHODS Between January 1993 and October 1994, 604 patients above 65 years of age who underwent non-emergent open heart operations were followed prospectively over a 2-year period. The Health Status Questionnaire forms were distributed to all patients preoperatively and to hospital survivors at 3, 12, and 24 months. The questionnaire contains 36 questions and is divided into eight categories. Follow-up was 100% complete with 99.6% of questionnaires returned. RESULTS Significant quality of life improvements were noted in all categories after surgery. After reaching a peak at 12 months, there were small, but significant declines in scores relating to physical health and health perception at 24 months. In contrast, measurements for mental attributes continued to increase with time. By multivariate analysis, diabetes, older age, and female gender had a relatively adverse influence on quality of life despite improvement after operation. Similarly, patients with chronic obstructive pulmonary disease or having redo operations had lower health perception with some physical limitations. While procedure type (coronary artery bypass grafting) was associated with preoperative bodily pain, congestive heart failure symptoms were not an independent factor affecting quality of life. CONCLUSIONS Quality of life improves with cardiac surgical interventions in this studied age group and should not be denied even in the elderly population.

Abstract
OBJECTIVE In recent years, satisfactory outcome of primary cardiac operation in octogenerians and increased ageing of cardiac surgical population in western hospitals have led to increased expectations and referrals for reoperation. Outcome of reoperation in this aged subset was analysed. METHODS Consecutive 18 octogenerians (mean age 81.2 years, 10 men, eight women) undergoing cardiac reoperations from November 1989 through August 1998 were retrospectively reviewed. RESULTS They represented 6.2% of all octogenerian cardiac surgical patients and 2.7% of all reoperations during the same period. Mean preoperative NYHA class was 3.4 and Parsonnet score was 29.4. The interval to reoperation was 114.5+/-11.96 (4-188) months. Priority was urgent in 11 and elective in seven patients. The procedures included four AVRs, five MVRs (including two associated TVAs), six CABGs and one each of MVR with CABG, AVR with CABG and AVR, MVR and CABG. Average graft/patient was 2.3. Mean ICU stay was 4.6+/-1.5 (1-28) days. There was one hospital death (5.5%) on 18 pod after MVR in an 83-year-old woman. Mean postoperative stay was 20.2+/-5.13 (8-93) days. There were three late deaths (17.6%)--at 32 months after MVR, at 44 and 63 months after CABG. Long-term survivors were 90% among men and 50% among women who were followed up for 42.7+/-6.9 (9-93) months. Mean Karnofsky score in survivors at 1 year of follow-up was 78.5+/-2.9. Despite continued medication in all survivors, mean current NYHA is 1.9 and most have improved lifestyle. CONCLUSIONS Satisfactory outcome may be expected after cardiac reoperations in highly selected octogenerians. However, increased procedural risks, complications, hospital stay and slower convalescence during early follow-up may be anticipated, and will indicate very careful screening. These results indicate a need to reconsider the treatment policy in primary operation with regard to choice of graft conduits and prosthetic valves in other elderly patients.

Abstract
BACKGROUND With the rapid growth of the elderly segment of the population, more octogenarians are referred for complex cardiac interventions, including reoperations. Data regarding the outcomes, quality of life, and long-term results after reoperative open-heart surgical procedures in octogenarians are scarce. METHODS We retrospectively studied 113 consecutive octogenarians (mean age, 83+/-2.6 years) who underwent reoperative cardiac procedures within a 13-year period. Coronary artery bypass grafting (CABG) was performed in 49 patients (CABG group), valvular procedures (aortic, mitral, or tricuspid valve, alone or in combination) in 35 (valve group), and combined CABG and valve intervention in 29 (combined CABG and valve group). RESULTS The 30-day mortality rate was 8% (4 of 49) for the CABG group, 9% (3 of 35) for the valve group, and 17% (5 of 29) for the combined CABG and valve group. One- and 5-year actuarial survival rates were, respectively, 85%+/-5% and 58%+/-10% for the CABG group, 78%+/-7% and 53%+/-12% for the valve group, and 69%+/-9% and 63%+/-10% for the combined CABG and valve group. Sixty-one percent of patients in the CABG group, 40% in the valve group, and 38% in the combined CABG and valve group were in New York Heart Association class I or II postoperatively at a mean follow-up time of 2.1+/-2.4 years. Similarly, 91%, 85%, and 80%, respectively, thought that they had an improved quality of life and were satisfied with their functional status. CONCLUSIONS Cardiac reoperations can be performed successfully in most octogenarians, although with an increased risk, particularly in the combined CABG and valve group. Long-term survival is acceptable with improved quality of life and functional status. However, it is possible that these results could be improved in this high-risk group of patients with earlier referral and surgical intervention, for the effective use of health care resources.

Abstract
BACKGROUND With the progressive aging of western populations, cardiac surgeons are increasingly faced with elderly patients. METHODS We reviewed the records of 191 consecutive patients aged 80 years or older (mean age, 83 +/- 2.4 years) who underwent a cardiac surgical procedure at our institution from 1991 through 1996. RESULTS Ninety-eight patients were men. Preoperatively, 32% of patients were in New York Heart Association class III or IV, and mean left ventricular ejection fraction was 0.55 +/- 0.02. One hundred ten patients (58%) underwent aortic valve replacement, 47 (25%) had coronary artery bypass grafting, 26 (14%) had combined aortic valve replacement and coronary artery bypass grafting, 5 (3%) underwent mitral valve replacement, and 3 (1.6%) had other procedures. Postoperative complications occurred in 69.1% of patients. The hospital mortality rate was 16.2%. Actuarial survival estimates at 1 year, 3 years, and 5 years were 79.2%, 74.9%, and 56.2%, respectively. Multivariate predictors (p < 0.05) of hospital death were preoperative pulmonary hypertension and lower left ventricular ejection fraction. Multivariate predictors of late death were combined aortic valve replacement and coronary artery bypass grafting and female sex. Sixty-four percent of long-term survivors were fully autonomous, and female sex was the only independent predictor of impaired autonomy. Eighty-three percent of survivors were satisfied with their present quality of life. CONCLUSIONS Cardiac operations can be performed in octogenarians with a favorable long-term outcome. Earlier referral and intervention is mandatory to improve results in this patient population.

Abstract
BACKGROUND Assessment of quality of life has become an increasingly important aspect of the risk-benefit analysis of any therapeutic intervention, particularly in high-risk populations, such as the elderly. METHODS Clinical outcomes of 147 consecutive patients older than 75 years undergoing valve surgery between 1992 and 1995 were reviewed. Long-term quality of life was assessed using a modified version of the Duke University Medical Outcomes Study system. RESULTS Mean age was 79.3+/-4 years, range was 75 to 89 years, and 67% (99/147) were male. Preoperatively, 128 patients (87%) were in New York Heart Association (NYHA) functional class III/IV. Fifty-two percent (77/147) of the operations were nonelective. Concomitant coronary artery bypass grafting was performed in 69 patients (47%). Thirty-day hospital mortality was 7.5% (11/147). Mean follow-up for 98% (133/136) of hospital survivors was 30+/-13 months (range, 2 to 55 months). Actuarial survival at 55 months was 71+/-6%-equivalent to a general age-, race-, and gender-matched population reported in the Life Tables of the US National Center for Health Statistics. At the time of follow-up, 112 patients (96%) lived at home, 78% (91/116) defined their health between good to excellent, and 81% (93/114) stated that the operation improved their health status. Ninety-seven percent (112/116) were able to bathe and dress independently, 92% (104/113) could walk at least one block, and 88.5% (100/113) could climb at least one flight of stairs. Moderate to vigorous activities could be performed by 59.2% (67/113). Overall, at the time of follow-up, 81% (95/117) were in NYHA class I/II. CONCLUSION In a selected patient population, valve surgery in the elderly is associated with acceptable early morbidity and mortality. Long-term survival and quality of life are excellent. These facts strongly support the performance of these procedures in patients older than 75 years.

Abstract
BACKGROUND Growth of the elderly population worldwide, and specifically in the United States, will continue to accelerate and will have a profound impact on the cost and delivery of health care resources in the future. A medical strategy that allows the elderly to live independently is essential to most cost-effective use of our resources. The question remains as to what will be the future of surgical therapy for this increasing population. METHODS We retrospectively studied the cases of 30 consecutive nonagenarians (mean age, 92.3 +/- 1.8 years) who underwent a cardiac operation within a 9-year period. All patients were in New York Heart Association class III or IV and underwent operation urgently or emergently. RESULTS The 30-day mortality rate was 10%, and the actuarial survival rates were 81% +/- 8% and 75% +/- 9% at 1 year and 2 years, respectively. Seventy-eight percent of survivors were in New York Heart Association class I or II within 2 years after operation and had an improved quality of life. The cost of providing care in this age group was 24% higher than in octogenarians. CONCLUSIONS Advanced age in and of itself (>90 years) should not be a contraindication to an open-heart operation, although morbidity, mortality, and cost may be higher. However, selective criteria identifying risks and benefits for individual patients should be applied. The aging of our population will have a profound impact on the cost and delivery of health care resources in the future. This issue must be addressed in the current debate on the provision of expensive procedures under a realigned national health-care system.

Abstract
BACKGROUND Age has been considered an important risk factor for cardiac operations. Recent refinements have been designed to reduce cardiac, neurologic, and renal complications. METHODS Analysis of cardiac surgical outcomes including mortality, length of stay, complications, and costs were undertaken for a consecutive series of 285 patients 70 years old and older and 568 patients younger than 70 years who underwent operation during 1991 through 1995. Management included antegrade and retrograde cold and warm blood cardioplegia, epicardial echocardiography, retrosternal dissection for reoperations, maintenance of "normal" arterial pressure, and measures to avoid renal dysfunction. Parsonnet risk stratification and multiple regression were used to account for risk factors. RESULTS The 30-day mortality rate for elderly patients was 1.8% (5/285) and 1.8% (10/568) for patients less than 70 years old (p = not significant). The hospital mortality rate for the elderly patients was 3.2% (9/285) versus 2.5% (14/568) for the younger group (p = not significant). The frequencies of complications were not different. Over the 5-year period, length of stay decreased from 12.5 +/- 1.5 days to 8.9 +/- 0.9 days for patients 70 years old and older and from 11.5 +/- 0.1 to 6.4 +/- 0.3 days for patients less than 70 years old. Hospital charges for the elderly group were 13% higher. CONCLUSIONS Modern cardiac surgical techniques and clinical practices have reduced the importance of the age factor.

Abstract
This is the first of a series of articles that discusses the pertinent issues involved in caring for patients undergoing surgery who belong to special populations. Octogenarians have higher mortality, more comorbidities, and special needs regarding convalescence. Patients with neuropsychiatric disorders may have exacerbations of their mental illness after surgery and require special care and patience by the nurse. Survival after cardiac surgery is similar in black and white patients, but the number of blacks having cardiac surgery is significantly and proportionately lower than whites, suggesting either a referral bias or a problem with access to care. Subsequent articles discuss cardiac surgery in women, during pregnancy, in Jehovah's Witnesses, and in patients with Down's Syndrome.
