Fifteen-Year Outcome Trends for Valve Surgery in North America

Carcinoid Heart Disease: A Review

Carcinoid heart disease remains a major cause of morbidity and mortality among patients with carcinoid syndrome and metastatic neuroendocrine tumors. Screening of all patients with N-terminal pro-B-type natriuretic peptide and transthoracic echocardiography is critical for early detection, as early symptoms and signs have low sensitivity for the disease. Cardiac surgery, in appropriate cases, is the only definitive therapy for advanced carcinoid heart disease, and it improves patient symptoms and survival. Management of carcinoid heart disease is complex, and multidisciplinary assessment of cardiac status, hormonal syndrome, and tumor burden is critical in guiding optimal timing of surgery.

Mechanisms of aortic stenosis

The pathobiology of degenerative aortic valve stenosis (AS) is complex and involves multiple features such as fibrosis, inflammation, oxidative stress, angiogenesis, hemorrhage, and osteogenic differentiation. We summarize the mechanism of valve calcification and angiogenesis which is necessary for calcifying processes. A promising therapeutic target is nuclear factor (NF)-κB which activates bone morphogenetic protein (BMP)2 via interleukin-6. BMP2 activates Wnt signaling via msh homeobox 2 causing osteogenic differentiation. BMP2 also activates Runx2/Cbfa1 which is an osteoblast-specific transcription factor. Signals in the hypoxia-inducible factor-2 axis activated by the NF-κB signaling pathway also play important role in calcifying processes including angiogenesis. The reason why angiogenesis takes place in avascular valves is still unknown, but it is likely angiogenesis and angiogenesis-related hemorrhage play critical roles in the progression of AS.

Impact of intrathecal morphine analgesia on the incidence of pulmonary complications after cardiac surgery: a single center propensity-matched cohort study

Background

Acute pain and systemic opioids may both negatively impact respiratory function after cardiac surgery. This study analyzes the local practice of using intrathecal morphine analgesia (ITMA) with minimal parenteral opioid administration in cardiac surgery, specifically the impact on postoperative pulmonary complications (PPCs).

Methods

Data from adult patients who underwent elective cardiac surgery between January 2002, and December 2013 in a single center were analyzed. Propensity scores estimating the likelihood of receiving ITMA were used to match (1:1) patients with ITMA and patients with intravenous analgesia (IVA). Primary outcome was PPCs, a composite endpoint including pneumonia, adult respiratory distress syndrome, and any type of acute respiratory failure. Secondary outcomes were in-hospital mortality, cardiovascular complications, and length of stay in the intensive care unit (ICU) and hospital.

Results

From a total of 1′543 patients, 920 were treated with ITMA and 623 with IVA. No adverse event consequent to the spinal puncture was reported. Propensity score matching created 557 balanced pairs. The occurrence of PPCs in patients with ITMA was 8.1% vs. 12.8% in patients with IVA (odds ratio, 0.6; 95% CI, 0.40–0.89; p = 0.012). Fewer patients with ITMA had a prolonged stay in the ICU (> 4 days; 16.5% vs. 21.2%, p = 0.047) or in the hospital (> 15 days; 25.5% vs. 31.8%. p = 0.024). In-hospital mortality and cardiovascular complications did not differ significantly between the two groups.

Conclusion

In this study involving cardiac surgical patients, ITMA was safely applied and was associated with fewer PPCs.

Minimally invasive valve surgery in high-risk patients

The use of minimally, or less invasive, approaches to cardiac valve surgery has increased over the past decade. Because of its less traumatic nature, early studies in lower risk patients demonstrated the approach to be associated with an enhanced recovery, increased patient satisfaction, and good operative outcomes. With time, despite a steep learning curve, surgeons expanded this approach to perform more complex procedures, and include patients with more co-morbidity. The aim of this publication is to review the current literature involving the use of minimally invasive valve surgery (MIVS) in higher-risk patients.

Outcomes of minimally invasive double valve surgery

BACKGROUND

Double valve surgery is associated with an increased peri-operative morbidity and mortality. A less invasive right thoracotomy approach may be a viable alternative to median sternotomy surgery in these higher-risk patients.

METHODS

We retrospectively analyzed the baseline demographics, operative characteristics, and post-operative outcomes of patients who underwent minimally invasive double valve surgery between January 2009 and December 2011 at our institution.

RESULTS

The cohort consisted of 117 patients, of which 68 (58.1%) were female. The mean age was 73±11 years, and the mean left ventricular ejection fraction was 52±11%. There were 43 (36.8%) patients with a history of congestive heart failure, 45 (38.5%) with chronic obstructive pulmonary disease, and 5 (4.3%) had a history of chronic kidney disease. The patients underwent primary (90.6%) or re-operative (9.4%) double valve surgery, which consisted of 50 (42.7%) aortic valve replacement and mitral valve repair, 31 (26.5%) mitral and tricuspid valve repair, 18 (15.4%) aortic and mitral valve replacement, 17 (14.5%) mitral valve replacement with tricuspid valve repair, and 1 (0.9%) aortic valve replacement with tricuspid valve repair. Post-operatively, there were 40 (34.2%) cases of prolonged ventilation, 9 (7.7%) acute kidney injury, 6 (5.1%) re-operations for bleeding, 1 (0.9%) cerebrovascular accident, and 15 (12.8%) cases of atrial fibrillation. The mean total hospital length of stay was 12±12 days, with an in-hospital mortality of 2 (1.7%).

CONCLUSIONS

A minimally invasive right thoracotomy approach to primary or re-operative double valve surgery is feasible, may be utilized with acceptable peri-operative morbidity and mortality.

Determinants of Late Tricuspid Regurgitation After Aortic-Mitral Double Valve Replacement

The aims of this study are to evaluate the long-term outcomes of double valve replacement (aortic and mitral valves) and to investigate the determinants of late tricuspid regurgitation (TR). A total of 239 consecutive patients who underwent double valve replacement were enrolled. Valve pathology was rheumatic in 86.6% (207/239) and degenerative in 13.4% (32/239) of patients. Among these patients, 116 patients underwent concomitant tricuspid annuloplasty, and follow-up was completed for all 239 patients (mean = 7.3 ± 4.1, maximum = 15.9 years). We used propensity score matching to match 67 patients without tricuspid annuloplasty to the 114 patients who underwent annuloplasty. There was 1 in-hospital death and 9.7% (23/238) of patients experienced late cardiac-related mortality. Analysis of aortic valves indicated that the transprosthetic mean pressure gradient increased with time (13.4 ± 5.2 vs 15.4 ± 9.0 mm Hg, p = 0.002). Aortic transprosthetic mean pressure gradient increased more notably in woman and was associated with late TR (odds ratio 1.1, p = 0.010). In patients with mild TR, those who underwent tricuspid valve repair were less likely to experience a cardiac-related death within 10 years of surgery (hazards ratio 6.1, p = 0.036).

Triple valve surgery through a less invasive approach: early and mid-term results

OBJECTIVES

A partial upper sternotomy has become established as a less invasive approach mainly for single and double valve surgery. This report evaluates the clinical outcomes of triple valve surgery performed through a partial upper sternotomy.

METHODS

We reviewed the medical records of 37 consecutive patients (28 men, 76%) who underwent triple valve surgery through a partial upper sternotomy between 2005 and 2015. The patients' mean age was 67 ± 17 years; 27 (73%) were in New York Heart Association Class III or IV. Aortic and mitral valve insufficiency was more common than stenosis. Ninety-three percent of surviving patients were followed for a mean period of 58 ± 24 months.

RESULTS

Aortic valve procedures consisted of 24 (65%) replacements and 13 (35%) repairs. The mitral valve was repaired in 28 (76%) patients, whereas tricuspid valve repair was feasible in all patients. No conversion to full sternotomy was necessary. Myocardial infarction was not observed. Chest tube drainage was 330 ± 190 ml, and 4 patients required reopening for bleeding (1, 3%) or tamponade (3, 8%). One stroke was observed due to heparin-induced thrombocytopaenia after initial unremarkable neurological recovery. Early mortality included 5 (13.5%) patients. Actuarial survival at 5 years was 52 ± 10%.

CONCLUSIONS

A partial upper sternotomy provides adequate exposure to all heart valves. We did not experience technical limitations with this approach. Wound dehiscence, postoperative bleeding, intensive care unit and hospital stay and early deaths were low compared to data from other published series of triple valve surgery through a full median sternotomy. Early and mid-term outcomes were not adversely affected by this less invasive approach.

Limited versus full sternotomy for aortic valve replacement

BACKGROUND

Aortic valve disease is a common condition that is easily treatable with cardiac surgery. This is conventionally performed by opening the sternum longitudinally down the centre ("median sternotomy") and replacing the valve under cardiopulmonary bypass. Median sternotomy is generally well tolerated, but as less invasive options have become available, the efficacy of limited incisions has been called into question. In particular, the effects of reducing the visibility and surgical access has raised safety concerns with regards to the placement of cannulae, venting of the heart, epicardial wire placement, and de-airing of the heart at the end of the procedure. These difficulties may increase operating times, affecting outcome. The benefits of smaller incisions are thought to include decreased pain; improved respiratory mechanics; reductions in wound infections, bleeding, and need for transfusion; shorter intensive care stay; better cosmesis; and a quicker return to normal activity.

OBJECTIVES

To assess the effects of minimally invasive aortic valve replacement via a limited sternotomy versus conventional aortic valve replacement via median sternotomy in people with aortic valve disease requiring surgical replacement.

SEARCH METHODS

We performed searches of CENTRAL, MEDLINE, Embase, clinical trials registries, and manufacturers' websites from inception to July 2016, with no language limitations. We reviewed references of identified papers to identify any further studies of relevance.

SELECTION CRITERIA

Randomised controlled trials comparing aortic valve replacement via a median sternotomy versus aortic valve replacement via a limited sternotomy. We excluded trials that performed other minimally invasive incisions such as mini-thoracotomies, port access, trans-apical, trans-femoral or robotic procedures. Although some well-conducted prospective and retrospective case-control and cohort studies exist, these were not included in this review.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial papers to extract data, assess quality, and identify risk of bias. A third review author provided arbitration where required. The quality of evidence was determined using the GRADE methodology and results of patient-relevant outcomes were summarised in a 'Summary of findings' table.

MAIN RESULTS

The review included seven trials with 511 participants. These included adults from centres in Austria, Spain, Italy, Germany, France, and Egypt. We performed 12 comparisons investigating the effects of minimally invasive limited upper hemi-sternotomy on aortic valve replacement as compared to surgery performed via full median sternotomy.There was no evidence of any effect of upper hemi-sternotomy on mortality versus full median sternotomy (risk ratio (RR) 1.01, 95% confidence interval (CI) 0.36 to 2.82; participants = 511; studies = 7; moderate quality). There was no evidence of an increase in cardiopulmonary bypass time with aortic valve replacement performed via an upper hemi-sternotomy (mean difference (MD) 3.02 minutes, 95% CI -4.10 to 10.14; participants = 311; studies = 5; low quality). There was no evidence of an increase in aortic cross-clamp time (MD 0.95 minutes, 95% CI -3.45 to 5.35; participants = 391; studies = 6; low quality). None of the included studies reported major adverse cardiac and cerebrovascular events as a composite end point.There was no evidence of an effect on length of hospital stay through limited hemi-sternotomy (MD -1.31 days, 95% CI -2.63 to 0.01; participants = 297; studies = 5; I2 = 89%; very low quality). Postoperative blood loss was lower in the upper hemi-sternotomy group (MD -158.00 mL, 95% CI -303.24 to -12.76; participants = 297; studies = 5; moderate quality). The evidence did not support a reduction in deep sternal wound infections (RR 0.71, 95% CI 0.22 to 2.30; participants = 511; studies = 7; moderate quality) or re-exploration (RR 1.01, 95% CI 0.48 to 2.13; participants = 511; studies = 7; moderate quality). There was no change in pain scores by upper hemi-sternotomy (standardised mean difference (SMD) -0.33, 95% CI -0.85 to 0.20; participants = 197; studies = 3; I2 = 70%; very low quality), but there was a small increase in postoperative pulmonary function tests with minimally invasive limited sternotomy (MD 1.98 % predicted FEV1, 95% CI 0.62 to 3.33; participants = 257; studies = 4; I2 = 28%; low quality). There was a small reduction in length of intensive care unit stays as a result of the minimally invasive upper hemi-sternotomy (MD -0.57 days, 95% CI -0.93 to -0.20; participants = 297; studies = 5; low quality). Postoperative atrial fibrillation was not reduced with minimally invasive aortic valve replacement through limited compared to full sternotomy (RR 0.60, 95% CI 0.07 to 4.89; participants = 240; studies = 3; moderate quality), neither were postoperative ventilation times (MD -1.12 hours, 95% CI -3.43 to 1.19; participants = 297; studies = 5; low quality). None of the included studies reported cost analyses.

AUTHORS' CONCLUSIONS

The evidence in this review was assessed as generally low to moderate quality. The study sample sizes were small and underpowered to demonstrate differences in outcomes with low event rates. Clinical heterogeneity both between and within studies is a relatively fixed feature of surgical trials, and this also contributed to the need for caution in interpreting results.Considering these limitations, there was uncertainty of the effect on mortality or extracorporeal support times with upper hemi-sternotomy for aortic valve replacement compared to full median sternotomy. The evidence to support a reduction in total hospital length of stay or intensive care stay was low in quality. There was also uncertainty of any difference in the rates of other, secondary outcome measures or adverse events with minimally invasive limited sternotomy approaches to aortic valve replacement.There appears to be uncertainty between minimally invasive aortic valve replacement via upper hemi-sternotomy and conventional aortic valve replacement via a full median sternotomy. Before widespread adoption of the minimally invasive approach can be recommended, there is a need for a well-designed and adequately powered prospective randomised controlled trial. Such a study would benefit from performing a robust cost analysis. Growing patient preference for minimally invasive techniques merits thorough quality-of-life analyses to be included as end points, as well as quantitative measures of physiological reserve.

Determinants of prolonged intensive care unit stay in patients after cardiac surgery: a prospective observational study

BACKGROUND

Prolonged intensive care unit (ICU) stay of patients after cardiac surgery has a major impact on overall cost and resource utilization. The aim of this study was to identify perioperative factors which prolong stay in ICU.

METHODS

All adult patients from a single, specialized cardiac center who were admitted to the ICU after cardiac surgery during a 2-month period were included. Demographic and clinical characteristics, comorbidities, preoperative use of drugs, intraoperative variables, and postoperative course were recorded. Hemodynamic and blood gas measurements were recorded at four time intervals during the first 24 postoperative hours. Routine hematologic and biochemical laboratory results were recorded preoperatively and in the first postoperative hours.

RESULTS

During the study period 145 adult patients underwent cardiac surgery: 65 (45%) underwent coronary artery bypass graft surgery, 38 (26%) valve surgery, 26 (18%) combined surgery and 16 (11%) other types of cardiac operation. Seventy nine (54%) patients had an ICU stay of less than 24 hours. Random forests analysis identified four variables that had a major impact on the length of stay (LOS) in ICU; these variables were subsequently entered in a logistic regression model: preoperative hemoglobin [odds ratio (OR) =0.68], duration of aortic clamping (OR =1.01) and ratio of arterial oxygen partial pressure to inspired oxygen fraction (PaO₂/FiO₂) (OR =0.99) and blood glucose during the first four postoperative hours (OR =1.02). ROC curve analysis showed an AUC =0.79, P<0.001, 95% CI: 0.71-0.86.

CONCLUSIONS

Low preoperative hemoglobin, prolonged aortic clamping time and low PaO₂/FiO₂ ratio and blood glucose measured within the first postoperative hours, were strongly related with prolonged LOS in ICU.

Transaortic Edge-To-Edge Repair for Functional Mitral Regurgitation during Aortic Valve Replacement: A 13-Year Experience

Objective

The study evaluated the feasibility of a transaortic edge-to-edge mitral valve repair (Alfieri stitch) for moderate or greater (≥2+) functional mitral regurgitation (MR) in high-risk patients undergoing aortic valve replacement.

Methods

We retrospectively evaluated 40 consecutive patients who underwent aortic valve replacement combined with a transaortic edge-to-edge mitral valve repair for 2+ or greater functional MR, between February 2002 and April 2015. The MR was graded semiquantitatively as 0 (trace/none), mild moderate (2+), or moderate to severe (3–4+).

Results

Thirty-two patients had aortic stenosis, and eight had aortic regurgitation. The mean ± standard deviation (SD) age was 77.5 ± 5 years, 34 (85%) were male, and the mean ± SD EuroSCORE II was 14.3% ± 12.9. At a median follow-up of 1 month (interquartile range, 0.75–10), there were significant improvements in preoperative versus postoperative median MR grade (3+ vs 1+, P < 0.001), mean left ventricular ejection fraction (34% vs 41%, P = 0.018), left ventricular end-diastolic diameter (54 vs 49 mm, P = 0.005), and pulmonary artery systolic pressure (49 vs 35 mm Hg, P < 0.001). Persistent 3 to 4+ MR occurred in two patients (5%). In 12 patients with at least 6-month follow-up (mean ± SD, 18 ± 11 months), a sustained improvement in all echocardiographic parameters was observed, with persistent 3 to 4+ MR occurring in one patient (8.3%). Actuarial survival at 1, 3, and 4.5 years was 82% ± 6, 71% ± 8, and 65% ± 10, respectively.

Conclusions

A transaortic edge-to-edge repair for 2+ or greater functional MR can be safely performed during aortic valve replacement and is associated with improvements in MR grade, left ventricular remodeling, and pulmonary hemodynamics.

Combined Mitral and Tricuspid Valve Surgery Performed via a Right Minithoracotomy Approach

OBJECTIVE

Combined mitral and tricuspid valve surgery is associated with an increased perioperative morbidity and mortality. We evaluated the outcomes of a less invasive right minithoracotomy approach in patients undergoing primary or reoperative double-valve surgery.

METHODS

We retrospectively evaluated 132 consecutive patients with mitral and tricuspid valve disease who underwent double-valve surgery via a right minithoracotomy at our institution between January 2009 and April 2014.

RESULTS

The cohort included 81 female (61%) and 51 male (39%) patients, with a mean ± SD age of 67 ± 13 years. The mean ± SD preoperative left ventricular ejection fraction, mitral regurgitation grade, and creatinine were 53% ± 12%, 3.8 ± 0.6, and 1.26 ± 1.17, respectively. The patients underwent primary (88%) or reoperative (12%) mitral and tricuspid valve surgery, which consisted of 88 mitral repairs (67%), 44 mitral replacements (33%), 131 tricuspid repairs (99%), and 1 tricuspid replacement (1%). Postoperatively, there were 6 cases of acute kidney injury (5%), 6 reoperations for bleeding (5%), 4 cerebrovascular accidents (3%), and 12 cases of atrial fibrillation (9%). The median intensive care unit length of stay and total hospital lengths of stay were 61 hours (interquartile range, 43-112 hours) and 8 days (interquartile range, 6-13 days), respectively. The in-hospital mortality was 4%. Actuarial survival at 1 and 5 years was 93% and 88%, respectively.

CONCLUSIONS

In patients undergoing primary or reoperative mitral and tricuspid valve surgery, a right minithoracotomy approach is associated with a low perioperative morbidity and good midterm survival.

Mitral valve repair for ischemic moderate mitral regurgitation in patients undergoing coronary artery bypass grafting

Objectives:

To investigate whether mitral valve repair (MVR) at the time of coronary artery bypass grafting (CABG) in patients with ischemic moderate mitral regurgitation (MR) and coronary artery disease could improve short- and mid-term postoperative outcomes.

Methods:

Between March 2013 and December 2015, 90 patients with moderate ischemic MR underwent first-time CABG in Bursa Yuksek Ihtisas Training and Research Hospital, Bursa, Turkey. Out of 90 patients, 44 (48.9%) underwent combined CABG+MVR. The remaining 46 (51.1%) underwent CABG alone. Ventricular functions and effort capacities of patients in both groups were evaluated echocardiographically and clinically in the preoperative period, and in the first postoperative year.

Results:

Postoperative regurgitant volume changes according to preoperative values were -24.76±19 ml/beat in the combined CABG+MVR group, and -8.70±7.2 ml/beat in the CABG alone group (p=0.001). The change of vena contracta width was -3.40±0.2 mm in the combined CABG+MVR group whereas in the CABG alone -1.45±0.7 mm (p=0.019). The changes of left ventricular end-systolic volume index were -30.77±25.9 ml/m² in the combined CABG+MVR group and -15.6±9.4 ml/m² in the CABG alone group (p=0.096). Ejection fraction changes in the combined CABG+MVR group was +1.51±5.3% and in the CABG alone group was +1.15±4.3%. No statistically significant difference was found between both groups (p=0.604). Preoperative New York Heart Association class values in the combined CABG+MVR group was 2.18±0.45, and in the CABG alone group was 2.13±0.54.

Conclusions:

Moderate MR in patients undergoing CABG affects the outcome adversely and it does not reliably improve after CABG alone. Therefore, patients with ischemic moderate MR should undergo simultaneous MVR at the time of CABG.

Pathophysiology and management of multivalvular disease

Multivalvular disease (MVD) is common among patients with valvular disease, and has a complex pathophysiology dependent on the specific combination of valve lesions. Diagnosis is challenging because several echocardiographic methods commonly used for the assessment of stenosis or regurgitation have been validated only in patients with single-valve disease. Decisions about the timing and type of treatment should be made by a multidisciplinary heart valve team, on a case-by-case basis. Several factors should be considered, including the severity and consequences of the MVD, the patient's life expectancy and comorbidities, the surgical risk associated with combined valve procedures, the long-term risk of morbidity and mortality associated with multiple valve prostheses, and the likelihood and risk of reoperation. The introduction of transcatheter valve therapies into clinical practice has provided new treatment options for patients with MVD, and decision-making algorithms on how to combine surgical and percutaneous treatment options are evolving rapidly. In this Review, we discuss the pathophysiology, diagnosis, and treatment of MVD, focusing on the combinations of valve pathologies that are most often encountered in clinical practice.

Calcific aortic stenosis

Calcific aortic stenosis (AS) is the most prevalent heart valve disorder in developed countries. It is characterized by progressive fibro-calcific remodelling and thickening of the aortic valve leaflets that, over years, evolve to cause severe obstruction to cardiac outflow. In developed countries, AS is the third-most frequent cardiovascular disease after coronary artery disease and systemic arterial hypertension, with a prevalence of 0.4% in the general population and 1.7% in the population >65 years old. Congenital abnormality (bicuspid valve) and older age are powerful risk factors for calcific AS. Metabolic syndrome and an elevated plasma level of lipoprotein(a) have also been associated with increased risk of calcific AS. The pathobiology of calcific AS is complex and involves genetic factors, lipoprotein deposition and oxidation, chronic inflammation, osteoblastic transition of cardiac valve interstitial cells and active leaflet calcification. Although no pharmacotherapy has proved to be effective in reducing the progression of AS, promising therapeutic targets include lipoprotein(a), the renin-angiotensin system, receptor activator of NF-κB ligand (RANKL; also known as TNFSF11) and ectonucleotidases. Currently, aortic valve replacement (AVR) remains the only effective treatment for severe AS. The diagnosis and staging of AS are based on the assessment of stenosis severity and left ventricular systolic function by Doppler echocardiography, and the presence of symptoms. The introduction of transcatheter AVR in the past decade has been a transformative therapeutic innovation for patients at high or prohibitive risk for surgical valve replacement, and this new technology might extend to lower-risk patients in the near future.

Improved Prediction by Dynamic Modeling: An Exploratory Study in the Adult Cardiac Surgery Database of the Netherlands Association for Cardio-Thoracic Surgery

BACKGROUND

The predictive performance of static risk prediction models such as EuroSCORE deteriorates over time. We aimed to explore different methods for continuous updating of EuroSCORE (dynamic modeling) to improve risk prediction.

METHODS AND RESULTS

Data on adult cardiac surgery from 2007 to 2012 (n=95 240) were extracted from the Netherlands Association for Cardio-Thoracic Surgery database. The logistic EuroSCORE predicting in-hospital death was updated using 6 methods: recalibrating the intercept of the logistic regression model; recalibrating the intercept and joint effects of the prognostic factors; re-estimating all prognostic factor effects, re-estimating all prognostic factor effects, and applying shrinkage of the estimates; applying a test procedure to select either of these; and a Bayesian learning strategy. Models were updated with 1 or 3 years of data, in all cardiac surgery or within operation subgroups. Performance was tested in the subsequent year according to discrimination (area under the receiver operating curve, area under the curve) and calibration (calibration slope and calibration-in-the-large). Compared with the original EuroSCORE, all updating methods resulted in improved calibration-in-the-large (range -0.17 to 0.04 versus -1.13 to -0.97, ideally 0.0). Calibration slope (range 0.92-1.15) and discrimination (area under the curve range 0.83-0.87) were similar across methods. In small subgroups, such as aortic valve replacement and aortic valve replacement+coronary artery bypass grafting, extensive updating using 1 year of data led to poorer performance than using the original EuroSCORE. The choice of updating method had little effect on benchmarking results of all cardiac surgery.

CONCLUSIONS

Several methods for dynamic modeling may result in good discrimination and superior calibration compared with the original EuroSCORE. For large populations, all methods are appropriate. For smaller subgroups, it is recommended to use data from multiple years or a Bayesian approach.

Early and Late Outcomes of Surgical Treatment in Carcinoid Heart Disease

BACKGROUND

Symptoms and survival of patients with carcinoid syndrome have improved, but development of carcinoid heart disease (CaHD) continues to decrease survival.

OBJECTIVES

This study aimed to analyze patient outcomes after valve surgery for CaHD during a 27-year period at 1 institution to determine early and late outcomes and opportunities for improved patient care.

METHODS

We retrospectively studied the short-term and long-term outcomes of all consecutive patients with CaHD who underwent valve replacement at our institution between 1985 and 2012.

RESULTS

The records of 195 patients with CaHD were analyzed. Pre-operative New York Heart Association class was III or IV in 125 of 178 patients (70%). All had tricuspid valve replacement (159 bioprostheses, 36 mechanical), and 157 underwent a pulmonary valve operation. Other concomitant operations included mitral valve procedure (11%), aortic valve procedure (9%), patent foramen ovale or atrial septal defect closure (23%), cardiac metastasectomies or biopsy (4%), and simultaneous coronary artery bypass (11%). There were 20 perioperative deaths (10%); after 2000, perioperative mortality was 6%. Survival rates (95% confidence intervals) at 1, 5, and 10 years were 69% (63% to 76%), 35% (28% to 43%), and 24% (18% to 32%), respectively. Overall mortality was associated with older age, cytotoxic chemotherapy, and tobacco use; 75% of survivors had symptomatic improvement at follow-up. Presymptomatic valve operation was not associated with late survival benefit.

CONCLUSIONS

Operative mortality associated with valve replacement surgery for CaHD has decreased. Symptomatic and survival benefit is noted in most patients when CaHD is managed by an experienced multidisciplinary team.

Development of the Cardiac Surgery Patient Expectations Questionnaire (C-SPEQ)

PURPOSE

Some variability in recovery and outcomes after cardiac surgery may be influenced by psychosocial aspects not routinely captured. Preliminary evidence suggests patient expectations impact health status, but there is no specific measure of expectations for cardiac surgery. The purpose of this study was to adapt an expectations scale to cardiac surgery and assess the psychometric properties of the scale.

METHODS

Before surgery, 93 patients awaiting non-emergent cardiac surgery completed questionnaires, including the adapted Cardiac Surgery Patient Expectations Questionnaire (C-SPEQ). At 1 year after surgery, 68 patients completed questionnaires.

RESULTS

Mean C-SPEQ score was 39.4 ± 9.02, and scores were normally distributed (Cronbach's alpha = 0.86). Higher score indicated negative expectations. Higher presurgery C-SPEQ score was correlated with greater depression (r = 0.32, p = 0.01) and perceived stress (r = 0.36, p = 0.003), but not state anxiety (r = 0.18, p = 0.14), at one-year post-surgery. Higher C-SPEQ was associated with longer recovery time (B = 0.14, p = 0.006) and lower physical HRQL after surgery (B = -0.31, p = 0.005). Higher C-SPEQ was not related to greater odds for perioperative complications (OR 1.01, p = 0.68) or readmissions <30 days (OR 1.05, p = 0.31). C-SPEQ score was not related to survival.

CONCLUSIONS

Adaptation of an expectations questionnaire to cardiac surgery patients was successful with acceptable reliability and validity. Negative expectations had a detrimental impact on recovery and HRQL following cardiac surgery but were not related to clinical outcomes. Although focus is mainly on improving clinical outcomes, there are opportunities to improve non-clinical aspects of the patient experience. Presurgical education might better prepare patients, reduce negative expectations, and improve psychosocial outcomes after cardiac surgery.

Impact of additive mitral valve surgery to coronary artery bypass grafting on mortality in patients with coronary artery disease and ischaemic mitral regurgitation: a systematic review and meta-analysis of randomized trials and observational studies

Aims

Treatment of ischaemic mitral regurgitation (IMR) remains controversial. While IMR is associated with worse outcomes, randomized controlled trials (RCTs) and observational studies provided conflicting evidence regarding the benefit of mitral valve replacement (MVR) or repair (MVr) in addition to coronary artery bypass grafting (CABG). We conducted a meta-analysis incorporating data from published RCTs and observational studies comparing CABG vs. CABG + MVR/MVr.

Methods and results

We searched PubMed, MEDLINE, Embase, Ovid, and Cochrane for RCTs and observational studies comparing CABG (Group 1) vs. CABG + MVR/MVr (Group 2). Outcome was 30-day and 1-year mortality after surgical intervention. Mantel-Haenszel odds ratio (OR) was calculated using random-effects meta-analysis for the outcome. Heterogeneity was assessed by I2 statistics. Four RCTs and 11 observational studies met the inclusion criteria (5781 patients, 507 in RCTs, 5274 in observational studies). Group 1 vs. 2 weighted mean left ventricular ejection fraction in RCTs and combined RCTs/observational studies was 41.5 ± 12.3 vs. 40.3 ± 10.4% ( P -value = 0.24) and 45.5 ± 7.2 vs. 38 ± 10% ( P -value < 0.001), respectively. In RCTs, there was no difference in 30-day [OR: 0.95, 95% confidence interval (95% CI): 0.30-3.08, P = 0.94] or 1-year (OR: 0.90, 95% CI: 0.43-1.87, P = 0.78) mortality, respectively. For combined RCTs/observational studies, there was no difference in mortality at 30 days (OR: 0.67, 95% CI: 0.43-1.04, P = 0.08) or at 1 year (OR: 0.90, 95% CI: 0.7-1.15, P = 0.39).

Conclusion

In a meta-analysis of RCTs and observational studies of IMR patients, the addition of MVR/MVr to CABG did not improve survival.

[Surgical techniques in mitral valve diseases. Reconstruction and/or replacement]

Mitral valve (MV) disease is one of the most common heart valve diseases. The surgical and interventional treatment for MV disease requires a multidisciplinary approach. For primary mitral valve regurgitation (MVR) surgical MV repair is the treatment of choice, which can be performed with an excellent outcome and long-term survival in reference centers. The surgical technique used for MV repair depends on the pathological mechanism, the morphological dimensions of the MV, the operative risk and the expertise of the cardiac surgeon. The surgical and interventional treatment of secondary MVVR is the subject of on-going discussions. In patients with moderate secondary MVR undergoing coronary artery bypass grafting, concomitant MV repair should be performed. In the presence of severe secondary MR with risk factors for failure of MV repair, patients should consider having MV replacement. In the rare cases of patients presenting with mitral valve stenosis (MVS) MV repair can be considered in young patients and who are most often treated with MV replacement. The choice between biological or mechanical MV replacement depends on the pathophysiology, the comorbidities, the amount of anticoagulation necessary and the age of the patient. New percutaneous techniques for MV replacement offer new treatment options for reoperation in high-risk patients.

Comparison of Inhospital Outcomes of Surgical Aortic Valve Replacement in Hospitals With and Without Availability of a Transcatheter Aortic Valve Implantation Program (from a Nationally Representative Database)

We hypothesized that the availability of a transcatheter aortic valve implantation (TAVI) program in hospitals impacts the overall management of patients with aortic valve disease and hence may also improve postprocedural outcomes of conventional surgical aortic valve replacement (SAVR). The aim of the present study was to compare the inhospital outcomes of SAVR in centers with versus without availability of a TAVI program in an unrestricted large nationwide patient population >50 years of age. SAVRs performed on patients aged >50 years were identified from the Nationwide Inpatient Sample (NIS) for the years 2011 and 2012 using the International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes. SAVR cases were divided into 2 categories: those performed at hospitals with a TAVI program (SAVR-TAVI) and those without (SAVR-non-TAVI). A total of 9,674 SAVR procedures were identified: 4,526 (46.79%) in the SAVR-TAVI group and 5,148 (53.21%) in SAVR-non-TAVI group. The mean age of the study population was 70.2 ± 0.1 years with majority (53%) of the patients aged >70 years. The mean Charlson's co-morbidity score for patients in SAVR-TAVI group was greater (greater percentage of patients were aged >80 years, had hypertension, congestive heart failure, renal failure, and peripheral arterial disease) than that of patients in SAVR-non-TAVI group (1.6 vs 1.4, p <0.001). The propensity score matching analysis showed a statistically significant lower inhospital mortality (1.25% vs 1.72%, p = 0.001) and complications rate (35.6% vs 37.3%, p = 0.004) in SAVR-TAVI group compared to SAVR-non-TAVI group. The mean length of hospital stay was similar in the 2 groups the cost of hospitalization was higher in the SAVR-TAVI group ($43,894 ± 483 vs $41,032 ± 473, p <0.0001). Having a TAVI program was a significant predictor of reduced mortality and complications rate after SAVR in multivariate analysis. In conclusion, this largest direct comparative analysis demonstrates that SAVRs performed in centers with a TAVI program are associated with significantly lower mortality and complications rates compared to those performed in centers without a TAVI program.

Using cardiac magnetic resonance imaging to evaluate cardiac function and predict outcomes in patients with valvular heart disease

OBJECTIVE

In valvular heart disease, elevated left atrial and pulmonary pressures contribute to right ventricular strain and, ultimately, right ventricle failure. Elevated pulmonary artery (PAP) and left ventricular end diastolic pressures are used as markers of right ventricle dysfunction and correlate with poor outcomes. Using cardiac magnetic resonance imaging (CMR), it is possible to directly quantify both left and right ventricular ejection function (LVEF and RVEF), and here, we compare CMR with traditional markers as outcome predictors.

METHODS

A retrospective review of prospectively collected data was performed for patients from January 2004 to February 2008 at a single center (n = 103). Patients were divided into those receiving CMR (n = 56) and those receiving only catheterization (n = 47). Univariate and multivariate logistic regression models were applied to determine predictors of mortality. Finally, predictive models for mortality using PAP, mean PAP, and left ventricular end diastolic pressure were compared to models using LVEF and RVEF obtained from CMR.

RESULTS

Preoperative average CMR LVEF and RVEF were 57% and 46%, respectively. Only age emerged as an isolated predictor of mortality (P = 0.01) within the univariate models. Stepwise regression models were created using the catheterization or CMR data. When compared, the CMR model has a slightly better R, c (prediction accuracy), and sensitivity/specificity (0.22 vs 0.28, 0.77 vs 0.82, and 0.63/0.62 vs 0.69/0.64, respectively).

CONCLUSIONS

Within our population, LVEF and RVEF predict mortality as least as well as traditional catheterization values. Additionally, CMR may identify of elevated PAPs caused by right ventricle dysfunction and those due to other causes, allowing these other causes to be addressed preoperatively.

Sources of Variation in Hospital-Level Infection Rates After Coronary Artery Bypass Grafting: An Analysis of The Society of Thoracic Surgeons Adult Heart Surgery Database

BACKGROUND

Patients undergoing coronary artery bypass grafting (CABG) are at risk for a variety of infections. Investigators have focused on predictors of these adverse sequelae, but less attention has been focused on characterizing hospital-level variability in these outcomes.

METHODS

Between July 2011 and December 2013, The Society of Thoracic Surgeons Adult Cardiac Surgery Database shows 365,686 patients underwent isolated CABG in 1,084 hospitals. Hospital-acquired infections (HAIs) were defined as pneumonia, sepsis/septicemia, deep sternal wound infection/mediastinitis, vein harvest/cannulation site infection, or thoracotomy infection. Hospitals were ranked by their HAI rate as low (≤ 10th percentile), medium (10th to 90th percentile), and high (>90th percentile). Differences in perioperative factors and composite morbidity and mortality end points across these groups were determined using the Wilcoxon rank sum and χ(2) tests.

RESULTS

HAIs occurred among 3.97% of patients overall, but rates varied across hospital groups (low: <0.84%, medium: 0.84% to 8.41%, high: >8.41%). Pneumonia (2.98%) was the most common HAI, followed by sepsis/septicemia (0.84%). Patients at high-rate hospitals more often smoked, had diabetes, chronic lung disease, New York Heart Association Functional Classification III to IV, and received blood products (p < 0.001); however, they less often were prescribed the appropriate antibiotics (p < 0.001). Major morbidity and mortality occurred among 12.3% of patients, although this varied by hospital group (low: 8.6%, medium: 12.3%, high: 17.9%; p < 0.001).

CONCLUSIONS

Substantial hospital-level variation exists in postoperative HAIs among patients undergoing CABG, driven predominantly by pneumonia. Given the relatively small absolute differences in comorbidities across hospital groups, our findings suggest factors other than case mix may explain the observed variation in HAI rates.

Exercise-based cardiac rehabilitation after heart valve surgery: cost analysis of healthcare use and sick leave

Background

Owing to a lack of evidence, patients undergoing heart valve surgery have been offered exercise-based cardiac rehabilitation (CR) since 2009 based on recommendations for patients with ischaemic heart disease in Denmark. The aim of this study was to investigate the impact of CR on the costs of healthcare use and sick leave among heart valve surgery patients over 12 months post surgery.

Methods

We conducted a nationwide survey on the CR participation of all patients having undergone valve surgery between 1 January 2011 and 30 June 2011 (n=667). Among the responders (n=500, 75%), the resource use categories of primary and secondary healthcare, prescription medication and sick leave were analysed for CR participants (n=277) and non-participants (n=223) over 12 months. A difference-in-difference analysis was undertaken. All estimates were presented as the means per patient (95% CI) based on non-parametric bootstrapping of SEs.

Results

Total costs during the 12 months following surgery were €16 065 per patient (95% CI 13 730 to 18 399) in the CR group and €15 182 (12 695 to 17 670) in the non-CR group. CR led to 5.6 (2.9 to 8.3, p<0.01) more outpatient visits per patient. No statistically significant differences in other cost categories or total costs €1330 (−4427 to 7086, p=0.65) were found between the groups.

Conclusions

CR, as provided in Denmark, can be considered cost neutral. CR is associated with more outpatient visits, but CR participation potentially offsets more expensive outpatient visits. Further studies should investigate the benefits of CR to heart valve surgery patients as part of a formal cost-utility analysis.

National Trends in Hospital Readmission Rates among Medicare Fee-for-Service Survivors of Mitral Valve Surgery, 1999-2010

Background

Older patients who undergo mitral valve surgery (MVS) have high 1-year survival rates, but little is known about the experience of survivors. Our objective was to determine trends in 1-year hospital readmission rates and length of stay (LOS) in these individuals.

Methods

We included 100% of Medicare Fee-for-Service patients ≥65 years of age who underwent MVS between 1999–2010 and survived to 1 year (N = 146,877). We used proportional hazards regression to analyze the post-MVS 1-year readmission rate in each year, mean hospital LOS (after index admission), and readmission rates by subgroups (age, sex, race).

Results

The 1-year survival rate among patients undergoing MVS was 81.3%. Among survivors, 49.1% experienced a hospital readmission within 1 year. The post-MVS 1-year readmission rate declined from 1999–2010 (49.5% to 46.9%, P<0.01), and mean hospital LOS decreased from 6.2 to 5.3 (P<0.01). Readmission rates were highest in oldest patients, but declined in all age subgroups (65–74: 47.4% to 44.4%; 75–84: 51.4% to 49.2%, ≥85: 56.4% to 50.0%, all P<0.01). There were declines in women and men (women: 51.7% to 50.8%, P<0.01; men: 46.9% to 43.0%, P<0.01), and in whites and patients of other race, but not in blacks (whites: 49.0% to 46.2%, P<0.01; other: 55.0% to 48.9%, P<0.01; blacks: 58.1% to 59.0%, P = 0.18).

Conclusions

Among older adults surviving MVS to 1 year, slightly fewer than half experience a hospital readmission. There has been a modest decline in both the readmission rate and LOS over time, with worse outcomes in women and blacks.

Surgical treatment of moderate ischemic mitral regurgitation

BACKGROUND

Ischemic mitral regurgitation is associated with increased mortality and morbidity. For surgical patients with moderate regurgitation, the benefits of adding mitral-valve repair to coronary-artery bypass grafting (CABG) are uncertain.

METHODS

We randomly assigned 301 patients with moderate ischemic mitral regurgitation to CABG alone or CABG plus mitral-valve repair (combined procedure). The primary end point was the left ventricular end-systolic volume index (LVESVI), a measure of left ventricular remodeling, at 1 year. This end point was assessed with the use of a Wilcoxon rank-sum test in which deaths were categorized as the lowest LVESVI rank.

RESULTS

At 1 year, the mean LVESVI among surviving patients was 46.1±22.4 ml per square meter of body-surface area in the CABG-alone group and 49.6±31.5 ml per square meter in the combined-procedure group (mean change from baseline, -9.4 and -9.3 ml per square meter, respectively). The rate of death was 6.7% in the combined-procedure group and 7.3% in the CABG-alone group (hazard ratio with mitral-valve repair, 0.90; 95% confidence interval, 0.38 to 2.12; P=0.81). The rank-based assessment of LVESVI at 1 year (incorporating deaths) showed no significant between-group difference (z score, 0.50; P=0.61). The addition of mitral-valve repair was associated with a longer bypass time (P<0.001), a longer hospital stay after surgery (P=0.002), and more neurologic events (P=0.03). Moderate or severe mitral regurgitation was less common in the combined-procedure group than in the CABG-alone group (11.2% vs. 31.0%, P<0.001). There were no significant between-group differences in major adverse cardiac or cerebrovascular events, deaths, readmissions, functional status, or quality of life at 1 year.

CONCLUSIONS

In patients with moderate ischemic mitral regurgitation, the addition of mitral-valve repair to CABG did not result in a higher degree of left ventricular reverse remodeling. Mitral-valve repair was associated with a reduced prevalence of moderate or severe mitral regurgitation but an increased number of untoward events. Thus, at 1 year, this trial did not show a clinically meaningful advantage of adding mitral-valve repair to CABG. Longer-term follow-up may determine whether the lower prevalence of mitral regurgitation translates into a net clinical benefit.

[Epidemiology of cerebral perioperative vascular accidents]

OBJECTIVES

Stroke is a well-described postoperative complication, after carotid and cardiac surgery. On the contrary, few studies are available concerning postoperative stroke in general non-cardiac non-carotid surgery. The high morbid-mortality of stroke justifies an extended analysis of recent literature.

ARTICLE TYPE

Systematic review.

DATA SOURCES

Firstly, Medline and Ovid databases using combination of stroke, cardiac surgery, carotid surgery, general non-cardiac non-carotid surgery as keywords; secondly, national and European epidemiologic databases; thirdly, expert and French health agency recommendations; lastly, reference book chapters.

RESULTS

In cardiac surgery, with an incidence varying from 1.2 to 10% according to procedure complexity, stroke occurs peroperatively in 50% of cases and during the first 48 postoperative hours for the others. The incidence of stroke after carotid surgery is 1 to 20% according to the technique used as well as operator skills. Postoperative stroke is a rare (0.15% as mean, extremes around 0.02 to 1%) complication in general surgery, it occurs generally after the 24-48th postoperative hours, exceptional peroperatively, and 40% of them occurring in the first postoperative week. It concerned mainly aged patient in high-risk surgeries (hip fracture, vascular surgery). Postoperative stroke was associated to an increase in perioperative mortality in comparison to non-postoperative stroke operated patients.

CONCLUSION

Postoperative stroke is a quality marker of the surgical teams' skill and has specific onset time and induces an increase of postoperative mortality.

Outcome characteristics of multiple-valve surgery: comparison with single-valve procedures

OBJECTIVE

Multiple-valve (MUV) procedures currently exhibit higher operative mortality than do single-valve procedures, but a paucity of scientific information exists to explain the observation. This topic was examined using The Society of Thoracic Surgeons Database.

METHODS

All patients in the The Society of Thoracic Surgeons data set undergoing valve surgery (except pulmonary valve and aortic root operations) from 1993 through 2007 were identified (N = 623,039). Baseline characteristics and postoperative outcomes were contrasted between all seven combinations of single-valve and MUV procedures involving aortic, mitral, and tricuspid valves. Seven independent logistic regression analyses were performed, based on the seven procedures, and multivariable risk factors for mortality were compared, with emphasis on single-valve versus MUV procedures.

RESULTS

Baseline characteristics for MUV procedures (n = 67,926) shared many similarities to those for single-valve procedures (n = 555,113), including age, ejection fraction, and comorbidities. Preoperative renal failure, New York Heart Association class III to IV, nonelective presentation, and reoperation were slightly more common in MUV subsets, and coronary bypass was less frequent. Operative mortality was almost double for MUV as compared with single-valve procedures (10.7% vs 5.7%, P = 0.0001). Categorical predictors with the largest odds ratios for mortality were emergency status, renal failure, and second reoperation. However, predictors for mortality were generally consistent in order and magnitude between the single-valve and MUV subgroups.

CONCLUSIONS

Despite similarities in preoperative profiles of the patients undergoing single-valve and MUV procedures, mortality for MUV surgery remains considerably higher. Determinants of operative mortality and morbidity differ little across the procedural groups, and these findings serve as a benchmark for future studies, as well as suggest a continued search for explanations of poorer MUV outcomes.

Right-sided valve disease

In this review, we discuss right-sided heart valve disease, namely tricuspid regurgitation (TR), tricuspid stenosis, pulmonary regurgitation, pulmonary stenosis and right-sided endocarditis. These are frequently seen in conjunction with other diseases, making assessment of their significance more difficult, but it has become increasingly clear that moderate or severe right-sided heart valve disease, in particular TR, is associated with worse prognosis. There remain large gaps in our knowledge of medical and interventional treatment, but in this article we outline what is known about the causes, presentation and management of these commonly seen conditions.

Transcatheter aortic valve replacement has improved short-term but similar midterm outcomes in isolated aortic valve replacement after prior coronary artery bypass grafting

BACKGROUND

An increasing number of patients with prior coronary artery bypass grafting (CABG) now present with severe aortic stenosis. The proposed benefit of surgical (SAVR) vs transcatheter aortic valve replacement (TAVR) is unknown. The objective of this study was to compare short-term and midterm outcomes of patients undergoing isolated SAVR vs TAVR in those with prior CABG.

METHODS

A retrospective analysis was performed of 255 patients who underwent isolated SAVR after prior CABG from January 2002 to February 2013 at Emory University. Outcomes of 148 patients undergoing SAVR (2002 to 2013) and 107 undergoing TAVR (2007 to 2013) were compared using multivariable logistic regression and analysis of variance techniques, adjusting for The Society of Thoracic Surgeons (STS) risk score. Kaplan-Meier plots were used to determine survival rates, and midterm survival between groups was compared using the Cox proportional hazards model.

RESULTS

TAVR patients were older (79.8 ± 7.9 years vs 72.5 ± 8.8 years, p < 0.001) but were gender equivalent (female: 24% vs 22%, p = 0.61). The preoperative ejection fraction was similar between groups (TAVR: 0.433 ± 0.131 vs SAVR: 0.469 ± 0.148%, p = 0.60). The TAVR group had a significantly higher the STS risk scores (11.8% vs 7.1%, p < 0.001). All-cause 30-day mortality was 1.9% for TAVR and 4.1% for SAVR (p = 0.32), a result that marginally favors TAVR after risk adjustment (adjusted odds ratio, 0.19; p = 0.07). Postoperative morbidity and resource utilization was significantly higher in the SAVR patients. Midterm survival was similar between the two groups after adjustment (adjusted hazard ratio, 0.78, p = 0.46).

CONCLUSIONS

Excellent outcomes can be achieved in SAVR or TAVR after prior CABG. Although TAVR improves short-term outcomes and resource utilization compared with SAVR, midterm mortality outcomes are similar.

The evolution of cardiovascular surgery in elderly patient: a review of current options and outcomes

Due to the increase in average life expectancy and the higher incidence of cardiovascular disease with advancing age, more elderly patients present for cardiac surgery nowadays. Advances in pre- and postoperative care have led to the possibility that an increasing number of elderly patients can be operated on safely and with a satisfactory outcome. Currently, coronary artery bypass surgery, aortic and mitral valve surgery, and major surgery of the aorta are performed in elderly patients. The data available show that most cardiac surgical procedures can be performed in elderly patients with a satisfactory outcome. Nevertheless, the risk for these patients is only acceptable in the absence of comorbidities. In particular, renal dysfunction, cerebrovascular disease, and poor clinical state are associated with a worse outcome in elderly patients. Careful patient selection, flawless surgery, meticulous hemostasis, perfect anesthesia, and adequate myocardial protection are basic requirements for the success of cardiac surgery in elderly patients. The care of elderly cardiac surgical patients can be improved only through the strict collaboration of geriatricians, anesthesiologists, cardiologists, and cardiac surgeons, in order to obtain a tailored treatment for each individual patient.
