Clinical and financial outcomes associated with the utilization of right internal mammary artery versus radial artery in multivessel coronary artery bypass grafting. Surgery 2024:S0039-6060(24)00235-6. [PMID: 38782703 DOI: 10.1016/j.surg.2024.04.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 03/30/2024] [Accepted: 04/06/2024] [Indexed: 05/25/2024]
Abstract
BACKGROUND Multi-arterial coronary bypass grafting with the left internal mammary artery as a conduit has been shown to offer superior long-term survival compared to single-arterial coronary bypass grafting. Nevertheless, the selection of a secondary conduit between the right internal mammary artery and the radial artery remains controversial. Using a national cohort, we examined the relationships between the right internal mammary artery and the radial artery with acute clinical and financial outcomes. METHODS Adults undergoing on-pump multivessel coronary bypass grafting with left internal mammary artery as the first arterial conduit were identified in the 2016 to 2020 Nationwide Readmissions Database. Patients receiving either the right internal mammary artery or the radial artery, but not both, were included in the analysis. Multivariable regression models were fitted to examine the association between the conduits and in-hospital mortality, as well as additional secondary outcomes. RESULTS Of an estimated 49,798 patients undergoing multi-arterial coronary bypass grafting, 29,729 (59.7%) comprised the radial artery cohort. During the study period, the proportion of multi-arterial coronary bypass grafting utilizing the radial artery increased from 51.3% to 65.2% (nptrend <0.001). Following adjustment, the radial artery was associated with reduced odds of in-hospital mortality (adjusted odds ratio 0.44), prolonged mechanical ventilation (adjusted odds ratio 0.78), infectious complications (adjusted odds ratio 0.69), and 30-day nonelective readmission (adjusted odds ratio 0.77, all P < .05). CONCLUSION Despite no definite endorsement from surgical societies, the radial artery is increasingly utilized as a secondary conduit in multi-arterial coronary bypass grafting. Compared to the right internal mammary artery, the radial artery was associated with lower odds of in-hospital mortality, complications, and reduced healthcare expenditures. These results suggest that whenever feasible, the radial artery should be the favored conduit over the right internal mammary artery. Nevertheless, future studies examining long-term outcomes associated with these vessels remain necessary.

Abstract
Objective This study determined hazard factors and long-term survival rate of total arterial coronary artery bypass graft surgery over 20 years in an extensively large, population-based cohort. Methods A total of 2979 patients who underwent isolated CABG from April 1999 to March 2020 were studied in 4 groups- Group-A (bilateral internal mammary artery ± radial artery), Group-B (single internal mammary artery + radial artery ± saphenous vein), Group-C (single internal mammary artery ± saphenous vein; no radial artery), and Group-D (radial artery ± saphenous vein; no internal mammary artery). The study endpoints analysed the correlation between the number and types of grafts with the survival time following isolated CABG surgery. Results The total arterial revascularization (Group A) group had an admirable mean long-term survival of ~19 years, compared to 18.6 years (Group B), 15.86 years (Group C), and 10.99 years (Group D). A Kaplan-Meier curve demonstrated confidence interval (CI) for study groups- (95% CI 18.33-19.94), (95% CI 18.14-19.06), (95% CI 15.40-16.32), and (95% CI 9.61-12.38) in Group A, B, C, D respectively. In the Holm-Sidak method analysis, significant associations existed between the number of arterial grafts and the long-term outcome. A statistically significant (P≤0.05) long-term survival advantage for arterial grafting was demonstrated, especially total arterial revascularisation over all other combinations except single internal mammary artery + radial artery grafting. Conclusion In this series, over 20 years, total arterial CABG use has excellent long-term survival, achieving complete myocardial revascularisation. There is no significant difference between the BIMA group and SIMA with radial artery. However, there is a reduced survival with decreased use of arterial conduits.

Sequential composite BIMA grafting for 3v-CAD: factors that predict successful outcome of the one-inflow and two-inflow revascularization techniques. Gen Thorac Cardiovasc Surg 2024:10.1007/s11748-024-02022-0. [PMID: 38509384 DOI: 10.1007/s11748-024-02022-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 02/25/2024] [Indexed: 03/22/2024]
Abstract
OBJECTIVE The effect of one-inflow and two-inflow coronary surgical revascularization techniques inclosing skeletonized double mammary artery (BIMA) as T-graft on outcome is studied. METHODS Early ad mid-term outcome of complete BIMA revascularization (C-T-BIMA) versus left-sided BIMA with right-sided aorto-coronary bypass (L-T-BIMA + R-CABG) is quantified and analyzed by multivariate logistic regression, Cox-regression, and Kaplan-Meier analysis in a series of 204 consecutive patients treated for triple-vessel coronary disease (3v-CAD). RESULTS The L-T-BIMA + R-CABG technique (n = 104) enables higher number of total (4.02 ± 0.87 vs. 3.71 ± 0.69, p = 0.015) and right-sided (1.21 ± 0.43 vs. 1.02 ± 0.32, p = 0.001) coronary anastomoses, improves total bypass flow (125.88 ± 92.41 vs. 82.50 ± 49.26 ml, p < 0.0001) and bypass flow/anastomosis (31.83 ± 23.9 vs.22.77 ± 14.23, p = 0.001), and enhances completeness of revascularization (84% vs.69%, p = 0.014) compared to C-T-BIMA strategy (n = 100), respectively. Although the incidence of MACCE was comparable in the two groups (8% vs.1.2%, p = 0.055), the progression of functional mitral regurgitation (FMR) was significantly lower after L-T-BIMA + R-CABG, then after C-T-BIMA (47% vs.64%, p = 0.017). The use of C-T-BIMA-technique (HR = 4.2, p = 0.01) and preoperative RCA occlusion (HR = 3.006, p = 0.023) predicted FMR progression, whereas L-T-Graft + R-CABG technique protected against it (X2 = 14.04, p < 0.0001) independent of the anatomic and clinical complexity (Syntax score I: HR = 16.2, p = 0.156, Syntax score II: HR = 1.901, p = 0.751), of early- (0.96% vs.2%, p = 0.617) and mid-term mortality (5.8% vs.4%, p = 0.748) when compared to C-T-BIMA, respectively. CONCLUSIONS The two-inflow coronary revascularization by L-T-BIMA + R-CABG better protects against FMR progression without increasing MACCE and mortality. Older patients with RCA occlusion and reduced LV-EF benefit most from the two-inflow L-T-BIMA + R-CABG technique. Younger 3v-CAD patients with normal LV-EF can preferentially be managed with the one-inflow C-T-BIMA; however, long-term outcome remains to be revealed.

Abstract
OBJECTIVE The optimal strategy for surgical revascularization in patients with impaired renal function is inconclusive. We compared early and late outcomes between bilateral internal thoracic artery (BITA) and single ITA (SITA) grafting in patients with renal dysfunction. METHODS This is a retrospective analysis of all the patients with multivessel disease and impaired renal function (estimated glomerular filtration rate <60mL/min/1.73m2) who underwent isolated coronary artery bypass graft (CABG) in our center during 1996-2011, utilizing either BITA or SITA revascularization. RESULTS Of the 5301 patients with multivessel disease who underwent surgical revascularization during the study period, 391 were with impaired renal function: 212 (54.2%) underwent BITA, 179 (45.8%) underwent SITA. Patients who underwent BITA were less likely to have comorbidities. Statistically significant differences were not observed between the BITA and SITA groups in 30-day mortality (5.6% vs. 9.0%, p = 0.2) and in rates of early stroke, myocardial infarction, and sternal infection (4.5% vs. 6.1%, p = 0.467; 1.7% vs. 2.8%, p = 0.517; and 2.2% vs. 5.7%, p = 0.088, respectively). Long-term survival of the BITA group was better: median 8.36 vs. 4.14 years, p<0.001. In multivariable analysis, BITA revascularization was associated with decreased late mortality (HR = 0.704, 95% CI: 0.556-0.89, p = 0.003). In analysis of a matched cohort (134 pairs), early outcomes did not differ between the groups; however, in multivariable analysis, BITA revascularization was associated with decreased late mortality (HR = 0.35 (95%CI 0.18-0.68), p = 0.002). CONCLUSIONS BITA revascularization did not impact early outcome in patients with CRF, but demonstrated a significant protective effect on long-term survival in the unmatched and matched cohorts.

Abstract
OBJECTIVES We explored the current evidence on the best second conduit in coronary surgery carrying out a double meta-analysis of propensity score matched or adjusted studies comparing bilateral internal thoracic artery (BITA) versus single internal thoracic artery plus radial artery. METHODS PubMed, Embase, and Google Scholar were searched for propensity score matched or adjusted studies comparing BITA versus single internal thoracic artery plus radial artery. The end point was long-term mortality. Two statistical approaches were used: the generic inverse variance method and the pooled meta-analysis of Kaplan-Meier-derived individual patient data. RESULTS Twelve matched populations comparing 6450 patients with BITA versus 9428 patients with single internal thoracic artery plus radial artery were included in our meta-analysis. The generic inverse variance method showed a statistically significant survival benefit of the BITA group (hazard ratio, 0.84; 95% CI, 0.74-0.95; P = .04). The Kaplan-Meier estimates of survival at 1, 5, 10, and 15 years of the BITA group were 97.0%, 91.3%, 80.0%, and 68.0%, respectively. The Kaplan-Meier estimates of survival at 1, 5, 10, and 15 years of the single internal thoracic artery plus radial artery group were 97.3%, 91.5%, 79.9%, and 63.9%, respectively. The Kaplan-Meier-derived individual patient data meta-analysis applied to very long follow-up time data, showed that BITA provided a survival benefit after 10 years from surgery (hazard ratio, 0.77; 95% CI, 0.63-0.94; P = .01). No differences in terms of survival between the 2 groups were detected when the analysis was focused on the first 10 years of follow-up (hazard ratio, 0.99; 95% CI, 0.91-1.09; P = .93). CONCLUSIONS The present meta-analysis suggests that double internal thoracic artery may provide, compared with single internal thoracic artery plus radial artery, a statistically significant survival advantage after 10 years of follow-up, but not before.

Abstract
Recent advances in coronary revascularization include total arterial grafting, however, in a few cases, harvesting the right internal thoracic artery (RITA) is not possible due to various reasons. In such cases, where the aorta is also calcified, few surgeons perform Y anastomosis configuration with the left internal thoracic artery(LITA) and saphenous vein which can have disastrous complications. Our patient is a 65-year-old man who was diagnosed with multivessel coronary disease and presented with a coronary steal during coronary artery bypass grafting surgery. The RITA was not harvested due to osteoporosis sternum. LITA-saphenous vein Y anastomosis configuration was done as the aorta was calcified. The anastomosis was done between the LITA to the left anterior descending (LAD) artery and the Y arm saphenous vein was anastomosed to an obtuse marginal (OM)branch. He developed coronary steal following anastomosis of the Y graft to the OM branch. The patient had ischemic changes inside the operation theatre in LAD territory, hence grafts were revised following which the patient became stable. There is a high possibility of a coronary steal when the caliber of the Y arm does not match with the LITA. LITA-saphenous vein Y anastomosis can cause more complications as the saphenous vein is much bigger in caliber compared to the LITA.

Abstract
Background It is unknown if the presence of saphenous vein grafting (SVG) adversely affects late survival following coronary surgery with multiple arterial grafting (MAG) versus single arterial grafting. Methods and Results A retrospective, observational, multicenter cohort study from 2001 to 2020 was conducted using the Australian and New Zealand Society of Cardiac and Thoracic Surgeons Database linked to the National Death Index. Patients undergoing primary isolated coronary artery bypass grafting with ≥2 grafts were included, and exclusions were patients aged <18 years, reoperations, concomitant or previous cardiac surgery, and the absence of arterial grafting. Demographics, comorbidities, medication, and operative configurations were propensity score matched between cohorts. The primary outcome was all-cause late death. Of 59 689 eligible patients, 35 113 were MAG (58.8%), and 24 576 were single arterial grafting (41.2%). Of the MAG cohort, 17 055 (48.6%) patients did not receive supplementary SVG (total arterial revascularization). Matching separately generated 22 764 patient pairs for MAG versus single arterial grafting, and 11 137 patient pairs for MAG with total arterial revascularization versus MAG with ≥1 supplementary vein grafts. At a median follow-up duration of 5.0 years postoperatively, the mortality rate was significantly lower for MAG than single arterial grafting (hazard ratio [HR], 0.79 [95% CI, 0.76-0.83]; P<0.001). The stratified MAG analysis found that MAG with total arterial revascularization had a lower risk of late death (HR, 0.85 [95% CI, 0.80-0.91]; P<0.001) compared with MAG with ≥1 supplementary vein grafts. Sensitivity analyses produced consistent outcomes as the primary analysis. Following adjustment for the presence of SVG in the Cox model, the survival advantage of incremental number of arteries was lost. Conclusions Multiple arterial grafting has significantly improved long-term survival compared with single arterial grafting. A further incremental survival benefit exists when no SVG is used.

Abstract
OBJECTIVES Autologous saphenous vein grafts (SVGs) are the most commonly used bypass conduits in coronary artery bypass grafting (CABG) with multivessel coronary artery disease. Although external support devices for SVGs have shown promising outcomes, the overall efficacy and safety remains controversial. We aimed to evaluate external stenting for SVGs in CABG versus non-stented SVGs. METHODS MEDLINE, EMBASE, Cochrane Library and clinicaltrails.gov were searched for randomized controlled trials (RCTs) to evaluate external-stented SVGs versus non-stented SVGs in CABG up to 31 August 2022. The risk ratio and mean difference with 95% confidence interval were analysed. The primary efficacy outcomes included intimal hyperplasia area and thickness. The secondary efficacy outcomes were graft failure (≥50% stenosis) and lumen diameter uniformity. RESULTS We pooled 438 patients from three RCTs. The external stented SVGs group showed significant reductions in intimal hyperplasia area (MD: -0.78, p < 0.001, I2 = 0%) and thickness (MD: -0.06, p < 0.001, I2 = 0%) compared to the non-stented SVGs group. Meanwhile, external support devices improved lumen uniformity with Fitzgibbon I classification (risk ratio (RR):1.1595, p = 0.05, I2 = 0%). SVG failure rates were not increased in the external stented SVGs group during the short follow-up period (RR: 1.14, p = 0.38, I2 = 0%). Furthermore, the incidences of mortality and major cardiac and cerebrovascular events were consistent with previous reports. CONCLUSIONS External support devices for SVGs significantly reduced the intimal hyperplasia area and thickness, and improved the lumen uniformity, assessed with the Fitzgibbon I classification. Meanwhile, they did not increase the overall SVG failure rate.

J Surg Res 2023; 291:139-150. [PMID: 37390593 DOI: 10.1016/j.jss.2023.04.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 04/04/2023] [Accepted: 04/29/2023] [Indexed: 07/02/2023]
Abstract
INTRODUCTION The left internal thoracic artery (LITA) is most commonly used to bypass the left anterior descending artery (LAD) given its well-established mortality benefit. In some cases, the grafting strategy necessitates placing the right internal thoracic artery (RITA) on the LAD. We compared outcomes in our robotic beating-heart totally endoscopic coronary bypass surgery (TECAB) population between patients receiving LITA versus RITA-LAD grafts. METHODS We retrospectively reviewed patients undergoing robotic TECAB with skeletonized ITA conduits over 9 y. Outcomes were compared between those receiving LITA (Group-1) versus RITA (Group-2) grafts to the LAD (with/without other grafts). End points were early angiographic patency (in patients undergoing hybrid revascularization) and mid-term mortality/major adverse cardiac/cerebrovascular events. A propensity matched subanalysis was performed comparing only patients who received bilateral ITA grafting in each group. RESULTS Society of Thoracic Surgeons predicted mortality risk score was higher in Group-2. Group-1 patients had lower incidence of multivessel disease (75% versus 96%, P ≤ 0.001). Early overall graft patency (97% versus 96%, P = 0.718) and LAD graft patency (98% versus 95%, P = 0.372) were equivalent. At mean 42-mo follow-up (longest 8.5 y), Group-1 had lower all-cause mortality but no difference in cardiac mortality or repeat revascularization. In the propensity matched subanalysis, mid-term outcomes were equivalent. CONCLUSIONS Grafting the LAD with the LITA or RITA during robotic beating-heart TECAB resulted in similar early outcomes and angiographic patency. RITA-LAD patients were more likely to have multivessel disease and higher Society of Thoracic Surgeons risk and had higher all-cause mortality at mid-term analysis but no difference in major adverse cardiac/cerebrovascular events, including cardiac mortality.

Abstract
BACKGROUND Despite supportive evidence and guidelines, the use of multiple arterial grafts (MAGs) in coronary artery bypass grafting remains low. We sought to determine surgeon perception of personal MAG use and compare this with actual MAG use. METHODS We conducted a statewide surgeon survey of MAG use, presence of a hospital MAG protocol, and barriers for MAG use, with a response rate of 78% (n = 25). Surgeon survey responses were compared with actual Society of Thoracic Surgeons patient data from January 1, 2017, to December 31, 2020 using χ2 or Fisher's exact tests. RESULTS Of 5299 patients who had first-time, nonemergent, isolated coronary artery bypass grafting (≥2 grafts) by responding surgeons, 16% received MAG (n = 825). MAG use in patients whose surgeons self-designated as "routine" MAG users was 21% vs 7% for "nonroutine" users. Surgeons with a hospital protocol for MAG use utilized MAG more often (18% vs 14%, P = .001). Surgeons who were unconvinced by the data on the benefits of MAGs used MAGs in 11% vs 22% in surgeons who were convinced. MAG use increased over time, particularly from before to after the survey (13.1% vs 30.5%, P < .001). CONCLUSIONS Although MAG use increased over time, barriers to routine use remain. In surgeons who reported routine use, only 21% of their patients received MAGs. Hospital protocols, education, and increased awareness may reduce barriers to use and encourage evidence-based clinical practice.

Abstract
BACKGROUND The types of graft conduits and surgical techniques may impact the long-term outcomes of patients after coronary artery bypass graft (CABG) revascularization. This study observed a long-term survival rate following CABG surgery over 20 years in the United Kingdom. METHODS A total of 2979 isolated CABG patients were studied from 1999 to 2020, and postoperative data were obtained from the hospital-recorded mortality by the data quality team of the information department. Postdischarge survival was estimated using the Kaplan-Meier method, and statistical significance was obtained with log-rank tests and the Gehan-Breslow test, and the Holm-Sidak method was used for multiple pairwise comparisons. RESULTS The study observed male predominance (80%), and the median age was statistically significant (P <0.001) among the groups, 66 years (interquartile range 58-73) and 72 years (interquartile range 66-78) in survivor and non-survivor groups, respectively. In the Holm-Sidak method analysis, the best survival rate (mean 18.7 years) was observed in the total arterial group with significantly decreased survival for the mixed arterial and venous group (mean 16.12 years) and only the vein group (10.44 years). The Cox regression model observed that the New York Heart Association (NYHA) class III-IV (HR 1.57), chest re-exploration (HR 2.14), preoperative dialysis (HR 3.13), and redo surgery (HR 3.04) were potential predictors of the postoperative mortality (P ≤0.05). CONCLUSION In our series over 20 years, albeit off-pump and on-pump CABG observed similar survival rates, the total arterial myocardial revascularization population has significantly better long-term survival benefits.

Abstract
Multiple arterial grafting (MAG) utilizes more than one arterial graft with any additional grafts being saphenous vein grafts (SVG). It remains an infrequently used coronary surgical revascularization technique, especially in elderly patients. Our study aims to evaluate the age-related association with the relative outcomes of multiple versus single arterial grafting (SAG). The Australian and New Zealand national registry was used to identify adult patients undergoing primary isolated CABG with at least two grafts. Exclusion criteria included reoperations, concomitant or previous cardiac surgery, and the absence of arterial grafting. Propensity score matching was used to match patient groups. The primary outcome was all-cause late mortality and the secondary outcomes were 30-day mortality and 30-day hospital readmission. We selected 69,624 eligible patients with a mean (standard deviation) age of 65.0 (10.2) years old. Matching between MAG and SAG generated 16,882 pairs of patients < 70 years old and 10,921 pairs of patients ≥ 70 years old. At a median [interquartile range] follow-up duration of 5.9 [3.2–9.6] years, MAG was associated with significantly reduced mortality compared to SAG (hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.68–0.78; p < 0.001) in the younger subgroup as well as the elderly subgroup (HR, 0.84; 95% CI, 0.79–0.88; p < 0.001). In conclusion, MAG offers a survival benefit over SAG, in both younger and elderly patients.

Late Clinical Outcomes of Total Arterial Revascularization or Multiple Arterial Grafting Compared to Conventional Single Arterial with Saphenous Vein Grafting for Coronary Surgery.

Abstract
Coronary surgery provides better long-term outcomes than percutaneous coronary intervention. Conventional practice is to use a single arterial conduit supplemented by saphenous vein grafts. The use of multiple arterial revascularization (MAG), or exclusive arterial revascularization (TAR), however, is reported as having improved late survival. Survival is a surrogate for graft failure that may lead to premature death, and improved survival reflects fewer graft failures in the non-conventional strategy groups. The reasons for not using MAG or TAR may be due to perceived technical difficulties, a lack of definitive large-scale randomized evidence, a lack of confidence in arterial conduits, or resources or time constraints. Most people consider radial artery (RA) grafting to be new, with use representing approximately 2-5% worldwide, despite select centers reporting routine use in most patients for decades with improved results. In conclusion, the current body of evidence supports more extensive use of total and multiple arterial revascularization procedures in the absence of contraindications.

Abstract
Ischemic heart disease is the leading cause of morbidity and mortality worldwide and may require coronary revascularization when more severe or symptomatic. Coronary artery bypass grafting (CABG) is the most common cardiac surgical procedure and can be performed with different bypass conduits and anastomotic techniques. Saphenous vein grafts (SVGs) are the most frequently used conduits for CABG, in addition to the left internal thoracic artery. Outcomes with a single internal thoracic artery and SVGs are favorable, and the long-term patency of SVGs may be improved through novel harvesting techniques, preservation methods, and optimal medical therapy. However, increasing evidence points towards the superiority of arterial grafts, especially in the form of multiple arterial grafting (MAG). Nevertheless, the uptake of MAG remains limited and variable, both as a result of technical complexity and a scarcity of conclusive randomized controlled trial evidence. Here, we present an overview of CABG techniques, harvesting methods, and anastomosis types to achieve total arterial revascularization and adopt MAG. We further narratively summarize the available evidence for MAG versus single arterial grafting to date and highlight remaining gaps and questions that require further study to elucidate the role of MAG in CABG.

Abstract
BACKGROUND Data comparing patients who undergo multiarterial grafting during coronary artery bypass grafting (CABG) vs percutaneous coronary intervention (PCI) in patients with multivessel coronary disease are scarce. This study addresses the relevance of using multiple arterial conduits vs PCI for appropriate patients. METHODS This retrospective study included all patients with coronary artery disease who underwent CABG with multiple arterial conduits or PCI. Propensity score matching was performed for baseline characteristics. Kaplan-Meier estimates, cumulative incidence, and freedom from major adverse cardiac and cerebrovascular events (MACCE) curves were performed. RESULTS The total patient population consisted of 3648 patients from 2011 to 2018 divided into 902 CABG patients and 2746 PCI patients. Patients were propensity matched (PCI, n = 838; CABG, n = 838). In the CABG cohort the left internal mammary artery was used in 837 patients (99.9%), the right internal mammary artery in 770 patients (92%), and radial arteries in 108 patients (12.9%). Patients in the PCI cohort had significantly higher 30-day mortality (24 [2.9%] vs 7 [0.8%], P < .01). Survival over follow-up (median, 4.9 years; range, 3.3-6.8) was better for the CABG cohort (730 [87.1%] vs 625 [74.6%], P < .01). Patients in the CABG cohort had greater freedom from MACCE (607 [72.4%] vs 339 [40.5%], P < .01). Cox multivariable regression showed that patients who underwent CABG had a significantly reduced risk of mortality (hazard ratio, 0.49; 95% confidence interval, 0.39-0.61; P < .01) and of MACCE (hazard ratio, 0.33; 95% confidence interval, 0.28-0.38; P < .01). CONCLUSIONS Patients with coronary artery disease who undergo CABG with multiple arterial conduits have significantly fewer major adverse events, improved survival, and reduced hospital readmissions.

Abstract
BACKGROUND AND AIM OF THE STUDY The mammary artery shows excellent long-term patency and encourages the use of skeletonized bilateral internal thoracic arteries (BITA) for coronary surgery. We analyzed the long-term outcome of patients operated for myocardial revascularization with BITA in a single center. MATERIALS AND METHODS Clinical data and surgical details of patients undergoing coronary surgery with BITA were prospectively collected and retrospectively analyzed. Selected variables were studied as risk factors for sternal wound complication and a subanalysis of clinical outcome for patients aged 70 years or greater was performed. A long-term follow-up of the study group is provided. RESULTS From January 2001 to November 2021, 750 patients underwent myocardial revascularization using BITA grafts (mean age: 61 ± 9.5 years; males: 91%) at our institute. Patients with triple-vessel disease were 81%, 15.3% of all procedures were performed off-pump and 3.6% were urgent cases. Hospital mortality was 0.5%. Sternal wound complication was observed in 67 patients (9.0%) with 7 deep sternal wound infections (0.9%). Female gender (odds ratios [OR]: 3.7, p < 0.01), BMI >30 (OR: 1.8, p = 0.04), smoking (OR: 1.8, p = 0.02), and chronic kidney failure (OR: 3.7, p = 0.05) were independent predictors for sternal complications. During a mean follow-up time of 8.7 ± 5.3 years, 34 patients (4.5%) underwent a repeated myocardial revascularization, and there were 89 all-cause deaths (11.9%) and the cumulative survival at 5, 10, 15, and 20 years was 97%, 89%, 76%, and 60% for the whole study group 92%, 74%, 47%, and 43% for the subgroup of elderly patients (mean age: 74 ± 3.5 years). CONCLUSIONS Use of skeletonized bilateral thoracic arteries shows low-rate of wound infection and good long-term outcome with low risk of repeated revascularizations, regardless of patients' age.

Abstract
AIMS Whether bilateral internal thoracic artery (BITA) grafting benefits elderly patients in coronary artery bypass grafting (CABG) remains unclear since they tend to have a limited life expectancy and severe comorbidities. We aim to evaluate the outcomes of BITA vs. single internal thoracic artery (SITA) grafting in elderly patients. METHODS AND RESULTS A meta-analysis was performed by database searching until May 2021. Studies comparing BITA and SITA grafting among elderly patients were included. One randomized controlled trial, nine propensity score matching, and six unmatched studies were identified, with a total of 18 146 patients (7422 received BITA grafting and 10 724 received SITA grafting). Compared with SITA grafting, BITA grafting had a higher risk of deep sternal wound infection (DSWI) [odds ratio: 1.67; 95% confidence interval (CI): 1.22-2.28], and this risk could not be significantly reduced by the skeletonization technique. Meanwhile, BITA grafting was associated with a higher long-term survival [hazard ratio: 0.83; 95% CI: 0.77-0.90], except for the octogenarian subgroup. Reconstructed Kaplan-Meier survival curves revealed 4-year, 8-year, and 12-year overall survival rates of 85.5%, 66.7%, and 45.3%, respectively, in the BITA group and 79.3%, 58.6%, and 34.9%, respectively, in the SITA group. No significant difference was observed in early mortality, perioperative myocardial infarction, perioperative cerebral vascular accidents, or re-exploration for bleeding. CONCLUSION Compared with SITA grafting, BITA grafting could provide a long-term survival benefit for elderly patients, although this benefit remained uncertain in octogenarians. Meanwhile, elderly patients who received BITA were associated with a higher risk of DSWI and such a risk could not be eliminated by the skeletonization technique.

Abstract
Abstract
OBJECTIVES
As definitive data from randomized controlled trials comparing the effect on long-term survival of using single internal mammary artery (SIMA) or bilateral internal mammary artery (BIMA) grafting are not yet available, observational studies allow for long-term follow-up in large and representative populations, which might complement the information potentially derived from randomized trials. To compare long-term survival in patients under 70 years of age undergoing SIMA or BIMA grafting.
METHODS
Retrospective analysis of 3384 consecutive patients under 70 years undergoing primary isolated coronary artery bypass grafting, performed from 2000 to 2015, in a Portuguese level III Hospital. We identified 2176 and 1208 patients from the study population who underwent SIMA and BIMA grafting, respectively. The primary end point was all-cause mortality at 10 years. We employed inverse probability weighting to restrict confounding by indication.
RESULTS
The mean age of the study population was 59.4 (± 7.6) years, and 567 (16.8%) were females. Inverse probability weighting was effective in eliminating differences in all significant baseline characteristics. Follow-up was 99.88% complete. The median follow-up time was 12.82 (interquartile range, 9.65, 16.74) years: the primary end point of all-cause mortality at 10 years occurred in 463 patients (21.3%) and 166 (13.7%) in the SIMA and BIMA grafting groups, respectively (hazard ratio, 0.78; 95% confidence interval, 0.66–0.92; P = 0.004).
CONCLUSIONS
Bilateral internal mammary grafting is associated with lower long-term mortality than single internal mammary grafting. Moreover, this survival benefit comes at no increased perioperative morbidity or mortality cost.

Abstract
Objective Advanced hybrid coronary revascularization is the integration of sternal-sparing multivessel coronary artery bypass grafting and percutaneous coronary intervention in patients with multivessel coronary artery disease. We sought to review our advanced hybrid coronary revascularization experience over an 8.5-year period using robotic totally endoscopic coronary artery bypass with bilateral internal thoracic artery grafts and percutaneous coronary intervention. Methods From August 2013 to February 2022, 664 patients underwent robotic totally endoscopic coronary artery bypass at our institution. Of the 293 patients who underwent totally endoscopic coronary artery bypass assigned to a hybrid revascularization strategy, 156 patients received bilateral internal thoracic artery grafts and are the subject of this review. Patients underwent percutaneous coronary intervention with drug-eluting stents before or after totally endoscopic coronary artery bypass. We reviewed early and midterm outcomes (up to 8 years) in this cohort of patients with intent-to-treat advanced hybrid coronary revascularization. Results The mean age of patients was 65 ± 10 years. The mean Society of Thoracic Surgeons predicted risk of mortality was 1.26 ± 1.56. Triple-vessel disease occurred in 94% of patients, and 17% of patients had 70% or more left-main disease. The mean operative time was 311 ± 54 minutes, and the mean hospital length of stay was 2.7 ± 1.1 days. All patients had bilateral internal thoracic artery grafts; the total number of grafts was 334. Eight seven percentage of patients had totally endoscopic coronary artery bypass ×2, and 13% of patients had totally endoscopic coronary artery bypass ×3. One patient received totally endoscopic coronary artery bypass ×4. The mean number of grafts per patient was 2.14 ± 0.4, and the mean number of vessels stented was 1.23 ± 0.5. There were no conversions, perioperative stroke, or myocardial infarction. Early mortality occurred in 2 patients. Early graft patency was 98% (209/214 grafts); left internal thoracic artery to left anterior descending patency was 100% (66/66 grafts). At 8-year follow-up in 155 patients (mean 39 ± 26 months), all-cause and cardiac-related mortality were 11.6% and 3.9%, respectively. Freedom from major adverse cardiac/cerebrovascular events including repeat revascularization was 94%. Conclusions In patients with multivessel coronary artery disease, integrating robotic totally endoscopic coronary artery bypass with bilateral internal thoracic artery and percutaneous coronary intervention resulted in excellent early and midterm outcomes. Further studies are warranted.

Abstract
Objective This study aimed to examine the feasibility and safety of minimally invasive cardiac surgery coronary artery bypass grafting using an ultrasonically skeletonized internal thoracic artery in the authors’ initial experience. Methods From February 2012 to May 2021, 247 consecutive patients who underwent minimally invasive coronary artery bypass grafting using an ultrasonically skeletonized internal thoracic artery were reviewed retrospectively. Internal thoracic arteries were harvested in a full skeletonized fashion using an ultrasonic scalpel via left minithoracotomy. Bilateral internal thoracic arteries were used in 108 patients, and the internal thoracic arteries as in situ grafts were used in 393 anastomoses. Total arterial revascularization was performed in 126 patients, and 142 patients underwent aortic nontouch minimally invasive coronary artery bypass grafting. Results The patients’ mean (range) age was 65.9 ± 11.5 (30-90) years. The mean (range) number of anastomoses performed was 2.6 ± 1.1 (1-6). Forty-six patients (18.6%) had 4 grafts, 94 patients (38.1%) had 3 grafts, and 60 patients (24.3%) had 2 grafts. Minimally invasive coronary artery bypass grafting was completed without conversion to sternotomy in all patients. Cardiopulmonary bypass was performed in 3 patients (1.2%), reinterventions due to bleeding were performed in 7 patients (2.8%), and chest wound infections were observed in 5 patients (2.0%). There was 1 (0.4%) mortality. Conclusions Minimally invasive coronary artery bypass grafting using an ultrasonically skeletonized internal thoracic artery is feasible and has shown good perioperative outcomes. This approach has the potential for further optimization with revascularization strategies.

Abstract
Patients who have undergone coronary artery bypass graft (CABG) surgery are susceptible to bypass graft failure and progression of native coronary artery disease. Although the saphenous vein graft (SVG) was traditionally the most-used conduit, arterial grafts (including the left and right internal thoracic arteries and the radial artery) have improved patency rates. However, the need for secondary revascularization remains common, and percutaneous coronary intervention (PCI) has become the most common modality of secondary revascularization after CABG surgery. Procedural characteristics and clinical outcomes differ considerably from those associated with PCI in patients without previous CABG surgery, owing to altered coronary anatomy and differences in conduit pathophysiology. In particular, SVG PCI carries an increased risk of complications, and operators are shifting their focus towards embolic protection strategies and complex native-vessel interventions, increasingly using SVGs as conduits to facilitate native-vessel PCI rather than pursuing SVG PCI. In this Review, we discuss the differences in conduit pathophysiology, changes in CABG surgery techniques, and the latest evidence in terms of PCI in patients with previous CABG surgery, with a particular emphasis on safety and long-term efficacy. We explore the subject of contemporary CABG surgery and subsequent percutaneous revascularization in this complex patient population.

Abstract
PURPOSE In this article, we reported on the up-to-date literature regarding skeletonized bilateral internal mammary artery (BIMA) flow and the effect on sternal perfusion. We also reviewed the pros and cons of the skeletonization technique versus the conventional pedicle technique for harvesting the BIMA. METHODS We performed an up-to-date review using the PubMed database, with a specific focus on the contemporary published literature. RESULTS BIMA skeletonization can preserve the sternal microcirculation, minimize tissue damage, and maintain blood supply to the chest wall at the tissue level. This effect is also apparent in diabetics. Deep sternal wound infection (DSWI) rates are significantly less with skeletonization versus the conventional pedicle technique and are comparable to single internal mammary artery harvesting. CONCLUSIONS Contemporary large-scale studies demonstrate that skeletonization of the BIMA increases conduit length, provides superior flow, reduces the incidence of DSWIs, and improves late survival. Hopefully, this review will increase awareness of the compelling evidence in favor of using skeletonized internal mammary arteries and stimulate increased uptake of BIMA revascularization surgery.

Abstract
OBJECTIVE This study aimed to elucidate whether the use of bilateral internal thoracic arteries (BITAs) confers additional survival benefits compared with a single internal thoracic artery (SITA) in total arterial grafting with the radial artery. METHODS Between 2002 and 2016, 617 patients underwent a bilateral in situ internal thoracic artery grafting with the radial artery as a composite I-graft (BITA-I group) and 516 patients underwent single in situ internal thoracic artery grafting with the radial artery as a composite Y-graft (SITA-Y group). All anastomoses were performed without cardiopulmonary bypass and aortic manipulation. Propensity score matching was performed to adjust covariates and compared the outcomes between the 2 groups. Subanalysis was also performed to evaluate the effects of the BITA-I group on survival according to the covariates using Cox proportional hazards regression analysis. RESULTS Propensity score matching yielded 348 well-matched pairs. Early postoperative outcomes were similar in the 2 groups. The BITA-I group showed significantly better survival than the SITA-Y group (79.3% vs 70.2% at 10 years, P = .015). The subanalysis revealed a significantly better survival in the BITA-I group among overall patients (hazard ratio, 0.68; 95% confidence interval, 0.49-0.93). There was a significant positive effect on survival in the BITA-I group among patients without comorbidities or those aged <77 years. CONCLUSIONS BITA grafting with the radial artery provides better long-term survival than SITA grafting with the radial artery, which is enhanced among patients aged <77 years with minimum comorbidities.

Abstract
AIM The guideline for coronary artery revascularization replaces the 2011 coronary artery bypass graft surgery and the 2011 and 2015 percutaneous coronary intervention guidelines, providing a patient-centric approach to guide clinicians in the treatment of patients with significant coronary artery disease undergoing coronary revascularization as well as the supporting documentation to encourage their use. METHODS A comprehensive literature search was conducted from May 2019 to September 2019, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from PubMed, EMBASE, the Cochrane Collaboration, CINHL Complete, and other relevant databases. Additional relevant studies, published through May 2021, were also considered. Structure: Coronary artery disease remains a leading cause of morbidity and mortality globally. Coronary revascularization is an important therapeutic option when managing patients with coronary artery disease. The 2021 coronary artery revascularization guideline provides recommendations based on contemporary evidence for the treatment of these patients. The recommendations present an evidence-based approach to managing patients with coronary artery disease who are being considered for coronary revascularization, with the intent to improve quality of care and align with patients' interests.

Abstract
BACKGROUND To investigate clinical outcomes of various arterial grafts (AGs) vs. saphenous vein grafts (VGs) to the right coronary system in patients who received left-side bilateral internal thoracic artery revascularization. METHODS We compared short- and long-term outcomes of all the patients operated in our center during 1996-2011, who received left-sided bilateral internal thoracic artery (left anterior descending and left circumflex) grafting and either a VG or an AG to the right coronary system. RESULTS Of 1691 patients, 983 received a VG and 708 received an AG to the right coronary system: 387 gastroepiploic arteries and 321 internal thoracic artery grafts. The median follow-up was 15.7 ± 0.32 years. For the VG and AG groups, early mortality (1.6% for VG and 1.3% for AG, p=0.55) and other early adverse outcomes did not differ. Long-term (up to 20 years) survival was similar (34.1 +/- 3.4% for VG vs. 36.0 +/-2% for AG, p=0.86). In multivariable analysis, VG to the right coronary artery was not found to be a predictor of inferior survival (hazard ratio: 0.99 95%CI 0.836-1.194, p=0.99). Comparing two propensity matched groups of 349 pairs with a VG or an AG, and accounting for the severity of the right coronary lesion, did not demonstrate differences in early outcome or late survival between the groups. CONCLUSIONS Early outcomes and long-term survival were comparable among patients who received left-sided bilateral internal thoracic artery revascularization, between various graft types to the right coronary system.

Abstract
Coronary artery bypass graft surgery (CABG) is an impactful treatment for coronary heart disease. Intimal hyperplasia is the central reason for the restenosis of vein grafts after CABG. The introduction of external vascular sheaths around VGs (VGs) can effectively inhibit intimal hyperplasia and ensure the patency of VGs. In this study, the well-known biodegradable copolymer poly (ε-caprolactone-co-L, L-lactide) (PLCL) was electrospun into high porosity external sheaths. The prednisone loaded in the PLCL sheath was slowly released during the degradation process of PLCL. Under the combined effects of sheath and prednisone, intimal hyperplasia was inhibited. For the cell experiments, all sheaths show low cytotoxicity to L929 cells at different concentrations at different time intervals. The ultrasonography and histological results showed prominent dilation and intimal hyperplasia of VG without sheath after two months of surgery. But there was no dilation in PLCL and PLCLPrednisone groups. Notably, the prednisone-loaded sheath group exhibited efficacy in inhibiting intimal hyperplasia and ensured graft patency.

Abstract
OBJECTIVE The optimal surgical approach for critically ill patients with complex coronary disease remains uncertain. We compared outcomes of bilateral internal thoracic artery (BITA) versus single ITA (SITA) revascularization in critical patients. METHODS We evaluated 394 consecutive critical patients with multi-vessel disease who underwent CABG during 1996-2001. Outcomes measured were early mortality, strokes, myocardial-infarctions, sternal infections, revisions for bleeding, and late survival. The critical preoperative state was acknowledged concisely by one or more of the following: preoperative ventricular tachycardia/fibrillation, aborted sudden cardiac death, or the need for mechanical ventilation or for preoperative insertion of intra-aortic-balloon counter-pulsation. RESULTS During the study period, 193 of our patients who underwent SITA and 201 who underwent BITA were in critical condition. The SITA group was older (mean 68.0 vs. 63.3 years, p = 0.001) and higher proportions were females (28.5% vs. 18.9% p = 0.025), after recent-MI (69.9% vs. 57.2% p = 0.009) and with left-main disease (38.3% vs. 49.3% p = .029); the median logistic EuroSCORE was higher (0.2898 vs. 0.1597, p<0.001). No statistically significant differences were observed between the SITA and BITA groups in 30-day mortality; and in rates of early CVA, MI and sternal infections (13.0% vs. 8.5%, p = 0.148; 4.1% vs. 6.0%, p = 0.49; 6.7% vs. 4.5%, p = 0.32 and 2.1% vs. 2.5%, p>0.99, respectively). Long-term survival (median follow-up of 15 years, interquartile-range: 13.57-15) was better in the BITA group (median 14.39 vs. 9.31± 0.9 years, p = 0.001). Propensity-score matching (132 matched pairs) also yielded similar early outcomes and improved long-term survival (median follow-up of 15 years, interquartile-range: 13.56-15) for the BITA group (median 12.49±1.71 vs. 7.63±0.99 years, p = 0.002). In multivariable analysis, BITA revascularization was found to be a predictor for improved survival (hazard-ratio of 0.419, 95%CI 0.23-0.76, p = 0.004). CONCLUSIONS This study demonstrated long-term survival benefit for BITA revascularization in patients in a critical pre-operative state who presented for surgical revascularization.

Abstract
INTRODUCTION Coronary artery bypass grafting (CABG) continues to be the most commonly performed cardiac surgical procedure in the world. The use of multiarterial grafting may confer a long-term survival benefit over the use of vein grafts. However, there is a paucity of data comparing the use of in situ versus free right internal mammary artery (RIMA) in isolated CABG. METHODS Patients that underwent isolated CABG between 2010 and 2018 where RIMA was used in addition to a left internal mammary artery graft. Patients with prior cardiac surgery or percutaneous coronary intervention were excluded. Propensity matching was used for subanalysis. Mortality and major adverse cardiac and cerebrovascular events (MACCE) were analyzed with Kaplan-Meier survival curves and Cox multivariable regression. Heart failure-specific readmissions were assessed with cumulative incidence curves with Fine and Gray competing risk regression. RESULTS A total of 667 patients underwent isolated CABG. Of those, 422 had free RIMA and 245 had in situ RIMA utilized. Mortality was similar between cohorts (p = 0.199) with 5-year mortality rates of 6.6% (free) and 4.1% (in situ). MACCE was similar between cohorts, with 5-year event rates of 33.6% and 33.9% (p = 0.99). RIMA style was not a significant predictor of any outcome. CONCLUSION There was no difference in long-term mortality, complications, MACCE, or heart failure readmissions when comparing a contemporary cohort of patients undergoing isolated CABG utilizing RIMA as a conduit. These data may allow surgeons to consider using RIMA either as an in situ or a free conduit.

Abstract
Observational evidence shows that the use of multiple arterial grafts (MAG) is associated with longer postoperative survival and improved clinical outcomes. The current European Society of Cardiology/European Association for Cardio-Thoracic Surgery Guidelines on myocardial revascularization recommend the use of MAG in appropriate patients. However, a significant volume-to-outcome relationship exists for MAG, and lack of sufficient experience is associated with increased operative risk. A stepwise approach to building experience with MAG allows successful implementation of this technique into routine coronary surgery practice.

Abstract
BACKGROUND The association of age with the outcomes of bilateral internal thoracic arteries (BITAs) versus single internal thoracic arteries (SITAs) for coronary bypass grafting (CABG) remains to be determined. OBJECTIVES The purpose of this study was to evaluate the association between age and BITA versus SITA outcomes in the Arterial Revascularization Trial. METHODS The primary endpoints were all-cause mortality and a composite of major adverse events, including all-cause mortality, myocardial infarction, or stroke. Secondary endpoints were bleeding complications and sternal wound complications up to 6 months after surgery. Multivariable fractional polynomials analysis and log-rank tests were used. RESULTS Age did not affect any of the explored outcomes in the overall BITA versus SITA comparison in the intention-to-treat analysis and in the analysis based on the number of arterial grafts received. However, when the intention-to-treat analysis was restricted to the populations of patients between age 50 and 70 years, younger patients in the BITA arm had a significantly lower incidence of major adverse events (p = 0.03). CONCLUSIONS Our results suggest that BITA may improve long-term outcome in younger patients, although more randomized data are needed to confirm this hypothesis.

From January 2011 to December 2018, the data of 78 consecutive patients (study group) with prior CABG, who received primary coronary angiography in the setting of ST-elevation myocardial infarction (STEMI) or non-ST-elevation myocardial infarction (NSTEMI), were screened. The study group was compared with another well-matched 78 patients without a history of CABG (control group). The information of the coronary angiograms and clinical data of both groups were analyzed. Multivariate conditional logistic regression models were constructed to test the association between PCI success rate and the prior CABG at age ≥65 and <65 years, respectively. Results The results revealed that the primary PCI success rate in the study group was significantly lower than in the control group (67.9% vs. 92.3%, P<0.001) and in-hospital mortality was significantly higher than in control group (11.5% vs. 2.5%, P=0.03). The multivariate logistic regression analysis indicated that the primary PCI success rate was significantly associated with the history of prior CABG both in young patients [age <65 years; odds ratio (OR) =5.26, 95% confidence interval (CI): 1.69–16.47] and elderly (age ≥65 years; OR =13.76, 95% CI: 2.72–69.75). Conclusions The patients who receive primary PCI with AMI and prior CABG have poor in-hospital outcomes, with low PCI success rates and high mortality.

Measures to Increase Use of Multiple Arterial Grafts for Isolated Coronary Artery Bypass Grafting. J Am Coll Surg 2021; 232:954-961. [PMID: 33636310 DOI: 10.1016/j.jamcollsurg.2021.02.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 02/05/2021] [Accepted: 02/08/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND Use of multiple arterial grafts (MAGs) provides superior patency and long-term survival benefit compared with venous grafts during coronary artery bypass grafting (CABG). However, MAGs are used infrequently for CABG. We hypothesized that specific measures introduced at our institution would lead to an increase in the use of MAGs. STUDY DESIGN Use of MAGs before and after introduction of bundled measures was compared. Measures included increased education in arterial graft harvesting, inclusion as a quality metric, and hiring of surgeon champions. Patients younger than 70 years who underwent first time, isolated CABG using at least 1 arterial graft were included. Number and type of grafts used were compared between time periods using chi-square test. Secondary outcomes included postoperative complications. Complications were compared between time periods, as well as between MAG and non-MAG recipients before and after propensity score matching using Fisher exact test and univariate logistic regression. Multivariable logistic regression was used to determine patient characteristics associated with MAG use. RESULTS There were 2,169 patients included from 2012 to 2019. MAG use increased significantly after introduction of measures (21.1% to 41.9%; p < 0.001). Radial artery use with an internal mammary artery (0.3% to 16%; p < 0.001) and the use of triple arterial grafts increased significantly (0% to 2.4%; p < 0.001). MAG use in the entire cohort was associated with decreased 30-day mortality and postoperative cardiac arrest that was not significant after propensity matching. CONCLUSIONS A programmatic emphasis on the use of MAGs for CABG is an effective method to increase its use.

Abstract
BACKGROUND This retrospective propensity matched study investigated the impact of age on the survival benefit from a second arterial conduit to the left-sided circulation. METHODS Data for isolated coronary artery bypass surgery were collected from October 2004 to March 2014. All patients with an internal mammary artery graft to left anterior descending artery and additional arterial or venous graft to the circumflex circulation were included. Propensity matching was used to balance co-variates and generate odds of death for each observation. Odds ratios (venous vs. arterial) were charted against age. RESULTS The in-hospital mortality rate was 1.12% (arterial) vs. 1.24% (venous) (p = 0.77). The overall 10-year survival was 74.6% (venous) vs. 82.6% (arterial) (p = 0.001). A total of 1226 patients were successfully matched to the venous or arterial (second conduit to circumflex territory after left internal mammary artery to left anterior descending artery) cohorts. Odds ratio for death (venous to arterial) showed a linear decremental overall survival benefit for the second arterial graft to circumflex circulation with increasing age. CONCLUSIONS The survival benefit of a second arterial graft persists through all age groups with a gradual decline with increasing age over the decades. Elderly patients should not be denied a second arterial graft to the circumflex circulation based on age criterion alone.

Abstract
It is unclear whether the additional conduit to supplement bilateral internal thoracic arteries (BITA) influences the patient outcome in coronary surgery. This retrospective study compared long-term survival of patients undergoing left-sided BITA grafting in which the third conduit to the right coronary system (RCA) was either vein graft (SVG) or gastroepiploic artery (GEA). From 1989 to 2014, 1432 consecutive patients underwent left-sided revascularization with BITA associated with SVG (n = 599) or GEA (n = 833) to RCA. Propensity score was calculated by logistic regression model and patients were matched 1 to 1 leading to 2 groups of 320 matched patients. The primary end point was the overall mortality from any cause. GEA was used in significantly lower risk patients. The 30-day mortality was 1.6% without influence of the graft configuration. Postoperative follow-up was 13.6 ± 6.6 years and was 94% complete. The significant difference in patients' survival observed at 20 years in favor of GEA in unmatched groups (48 ± 4% vs 33 ± 6%, P < 0.001) was not confirmed in matched groups (41 ± 7% vs 36 ± 7%, P = 0.112). In multivariable Cox model analysis, the conduit used to RCA did not influence the long-term survival in matched groups, like no other graft configuration or operative parameter. Only complete revascularization remained predictor of survival (P = 0.016), with age (P < 0.0001), diabetes status (P = 0.007), and left ventricle ejection fraction (P < 0.0001). Long-term survival in patients undergoing BITA grafting is not affected by using GEA as third arterial conduit in alternative to SVG. Further studies are necessary to assess its impact on long-term cardiac events.
