Cardiac solitary fibrous tumor - an extremely rare but potentially fatal diagnosis.

The background of this review is a description of the case of a 28-year-old man with an extremely rare cardiac solitary fibrous tumor (SFT). Although this tumor was removed surgically and in the 6-month follow-up examination no relapse was noted, recurrence was observed and confirmed in the magnetic resonance imaging 4 months later. SFT prevalence, symptoms and signs, treatment options and prognosis are reviewed.

The importance of the development of extracorporeal life support simulation centres for improving skills and knowledge during the COVID-19 pandemic.

Introduction: Despite increasing implementation of sophisticated and logistically challenging techniques to support patients in life-threatening conditions in the last years, there were no devoted education centres, especially in coronavirus pandemic. Aim: To assess the value of gaining evidence-based knowledge and improving the skills of physicians by means of simulation techniques in the safe use of extracorporeal technologies to support patients in the life-threatening conditions. Material and methods: In 2019, the National Education Centre for Artificial Life Support and Patient Safety and the frame program of the course of "Artificial Life Support with ECMO". was created. In years 2019-2023, we managed to organise 34 such courses for 405 physicians, which were additionally endorsed by ELSO (Extracorporeal Life Support Organisation). The physicians' cognitive, behavioural, and technical skills were evaluated before and after the courses. Results: The participants' gender was well balanced (54% men and 46% women). Most of them (mainly at the age between 31-40 years) presented more than 5 years of clinical experience, predominantly in anaesthesiology and intensive care (63%). Of note, 54% of them had no experience with ECMO application. In all detailed aspects of cognitive, behavioural, and technical assessment and knowledge scores, significant improvement was observed after the course. Conclusions: The development of a simulation-based education centre was found to be an invaluable achievement that enabled not only successful standardised training and testing of novel or previously accepted procedures, but also the upgrading of technical skills, even in the challenging COVID-19 pandemic period.

The Protective Effect of the Crosstalk between Zinc Hair Concentration and Lymphocyte Count-Preliminary Report.

BACKGROUND: An imbalance between pro- and anti-inflammatory mechanisms is indicated in the pathophysiology of atherosclerotic plaque. The coronary artery and carotid disease, despite sharing similar risk factors, are developed separately. The aim of this study was to analyze possible mechanisms between trace element hair-scalp concentrations and whole blood counts that favor atherosclerotic plaque progression in certain locations. METHODS: There were 65 (36 (55%) males and 29 (45%) females) patients with a median age of 68 (61-73) years enrolled in a prospective, preliminary, multicenter analysis. The study group was composed of 13 patients with stable coronary artery disease (CAD group) referred for surgical revascularization due to multivessel coronary disease, 34 patients with carotid artery disease (carotid group) admitted for vascular procedure, and 18 patients in a control group (control group). RESULTS: There was a significant difference between the CAD and carotid groups regarding lymphocyte (p = 0.004) counts. The biochemical comparison between the coronary and carotid groups revealed significant differences regarding chromium (Cr) (p = 0.002), copper (Cu) (p < 0.001), and zinc (Zn) (p < 0.001) concentrations. Spearman Rank Order Correlations between lymphocyte counts and trace elements in the analyzed groups were performed, revealing a strong correlation with zinc (R = 0.733, p < 0.001) in the control group (non-CAD, non-carotid). CONCLUSION: Significant differences in hair-scalp concentrations related to atherosclerosis location were observed in our analysis. The interplay between zinc concentration and lymphocyte count may play a pivotal role in cardiovascular disease development.

Extracellular Vesicles to Predict Outcomes After Transcatheter Aortic Valve Implantation - a Prospective, Multicenter Cohort Study.

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) is an established treatment for aortic stenosis (AS) in patients at intermediate and high surgical risk. Circulating extracellular vesicles (EVs) are nanoparticles involved in cardiovascular diseases. We aimed to (i) determine the effect of TAVI on plasma concentrations of five EV subtypes and (ii) evaluate the predictive value of EVs for post-TAVI outcomes. METHODS: Blood samples were collected 1 day before TAVI and at hospital discharge. Concentrations of EVs were evaluated using flow cytometry. RESULTS: Concentration of leukocytes EVs decreased after TAVI, compared to the measurement before (p = 0.008). Among 123 patients discharged from the hospital, 19.5% experienced MACCE during the median of 10.3 months. Increased pre-TAVI concentration of phosphatidylserine-exposing EVs was an independent predictor of MACCE in multivariable analysis (OR 5.313, 95% CI 1.164-24.258, p = 0.031). CONCLUSIONS: Patients with increased pre-TAVI concentration of procoagulant, PS-exposing EVs have over fivefold higher odds of adverse outcomes.

Impact of Incomplete Revascularization on Long-term Survival Based on Revascularization Strategy.

BACKGROUND: This study investigated the impact of complete revascularization (CR) and incomplete revascularization (IR) on long-term survival in patients undergoing isolated coronary artery bypass grafting (CABG) using multiple arterial graft (MAGs) or a single artery with saphenous vein grafts (SAGs). METHODS: Between January 2006 and December 2020, 12,625 patients underwent CABG and were divided into 4 groups: MAG CR (n = 1066), MAG IR (n = 286), SAG CR (n = 8360), and SAG IR (n = 2913). Inverse probability of treatment weighting based on the generalized propensity score was used to minimize imbalance between the groups. RESULTS: In the weighted cohort, median follow-up time was 8.35 years (interquartile range, 5.01-11.6 years). MAG CR was associated with similar long-term survival compared with MAG IR (hazard ratio [HR], 0.79; 95% CI, 0.60-1.03; P = .084). SAG CR was associated with improved long-term survival compared with SAG IR (HR, 0.67; 95% CI, 0.52-0.84; P = .01). MAG CR was associated with better long-term survival compared with SAG CR (HR, 0.45; 95% CI, 0.35-0.57; P < .001). Moreover, MAG IR was protective compared with SAG IR (HR, 0.62; 95% CI, 0.45-0.85; P = .033). Additional analysis was performed comparing perfect CR vs imperfect CR vs IR in MAG and SAG patients, separately. In the weighted sample of MAG, there were no differences in the long-term survival between perfect CR, imperfect CR, and IR. However, in the weighted sample of the SAG cohort, SAG perfect CR was associated with improved survival compared with SAG imperfect CR (HR, 0.81; 95% CI, 0.0.72-0.92; P = .001). Whereas, SAG perfect and imperfect CR were both associated with improved survival compared with SAG IR (HR, 0.51; 95% CI, 0.0.35-0.87; P = .006 and HR, 0.72; 95% CI, 0.64-0.82; P < .001), respectively. CONCLUSIONS: MAG CR is associated with better survival compared with SAG CR. If IR is inevitable, patients with MAG IR had better long-term survival compared with patients receiving SAG IR. Moreover, similar long-term survival is observed whether perfect CR, imperfect CR, or IR is achieved in the MAG population but not in SAG patients.

Anisocytosis as a possible predictor of low cardiac output syndrome in children undergoing mitral valve surgery.

PURPOSE: Mitral valve surgery in children involves correcting congenital and acquired pathologies, with a reported mortality rate of 0.9%. Low cardiac output syndrome (LCOS) is a serious complication with the incidence of 20-25%. The aim of the study was to estimate possible prognostic factors of LCOS in children undergoing mitral valve procedure. MATERIAL AND METHOD: This single-center retrospective analysis enrolled children aged <18 years who underwent mitral valve surgery during 24 year period. Preoperative clinical and laboratory parameters, and operative factors were analyzed. RESULTS: Thirty consecutive pediatric patients (11 (37%) males and 19 (63%) females) in median (Q1 - Q3) age of 57 (25-115) months, who underwent mitral valve replacement, were included. The 30-day mortality was 7% (2 patients) and was related to postoperative multiorgan failure. LCOS occurred in 8 (27%) children. The receiver operator curve (ROC) analysis established parameters that have predictive value for LCOS occurrence: cardiopulmonary bypass (CPB) time, with 89 â€‹min as optimal cut-off point (AUC â€‹= â€‹0.744, p â€‹= â€‹0.011) yielding sensitivity of 100% and specificity of 42.9%; left ventricular ejection fraction (LVEF) â€‹< â€‹60 % (AUC â€‹= â€‹0.824, okp â€‹= â€‹0.001) with sensitivity of 62.5% and specificity of 93.75%; and red blood cell distribution width (RDW) above 14.5 % (AUC â€‹= â€‹0.840, p â€‹< â€‹0.001; sensitivity of 87.5% and specificity of 75%). CONCLUSIONS: In mitral valve replacement in pediatric patients, CPBtime above 89 â€‹min, preoperative LVEF below 60% and preoperative RDW above 14.5% can be regarded as the potential predictors of LCOS.

The Interplay between Dyslipidemia and Neighboring Developments in Coronary Artery Disease Progression: A Personalized Approach.

(1) Background: Estimates suggest that up to 10% of global annual cardiovascular deaths could be related to environmental factors. Not only air pollution components, but also noise exposure and climate changes, are highlighted as nontraditional causes of cardiovascular morbidity. The aim of this study was to identify possible urbanization risk factors for the progression of coronary artery disease in a group of patients with chronic coronary syndrome. (2) Method: There were 77 patients (50 (65%) males and 27 (35%) females) with a median age of 70 (60-74) years who underwent repetitive angiography due to chronic coronary syndrome between 2018 and 2022. The Gensini score was calculated for assessment of coronary artery disease advancement. Environmental factors including neighboring developments were taken into account in this analysis, including housing, commercial, and industrial developments within 300, 500, and 700 m distances (buffer) from the place of habitation. (3) Results: The multivariable analysis results for prediction of Gensini score progression in relation to 700 m buffer urbanization pointed out the significance of hyperlipidemia (OR: 4.24, 95% CI 1.34-13.39, p = 0.014), initial Gensini score (OR: 1.02, 95% CI 1.00-1.05, p = 0.112), and neighborhood housing (OR: 0.03, 95% CI 0.01-0.49, p = 0.025). (4) Conclusions: Hyperlipidemia and housing neighborhood can be regarded as possible factors for coronary disease progression in patients with chronic coronary syndrome with the use of optimal medical therapy.

Single versus multiple arterial coronary artery bypass grafting in men and women: results from Polish National Registry of Cardiac Surgery Procedures.

BACKGROUND: The objective of this multicenter study aimed to investigate the impact of sex on long-term survival among patients with multivessel coronary artery disease undergoing coronary artery bypass grafting (CABG) using multiple arterial grafting (MAG) or a single artery with saphenous vein grafts. MATERIALS AND METHODS: Data were obtained from the Polish National Registry of Cardiac Surgery Procedures database. This study included 81 136 patients who underwent CABG for multivessel disease between January 2012 and December 2020 (22.9 were women and 77.1% were men). MAG was performed in 8.3 and 11.7% of female and male patients, respectively. A 1:1 propensity score (PS)-matching was performed. Long-term mortality was compared between matched groups of men and women. Subgroup analyses of patients aged <70 and ≥70 years, with an ejection fraction (EF) >40% and ≤40%, and with and without diabetes, obesity, peripheral artery disease (PAD), or chronic lung disease (CLD) were performed separately in women and men. RESULTS: MAG was associated with lower long-term mortality than saphenous vein grafts in 1528 PS-matched female pairs [hazard ratio (HR): 0.74; 95% CI: 0.59-0.92; P =0.007) and 7283 PS-matched male pairs (HR: 0.80; 95% CI: 0.72-0.88; P <0.001). Subgroup analyses confirmed the results among female patients aged <70 years, with diabetes and EF >40%, and without PAD or CLD, and of male patients aged <70 and ≥70 years; with EF >40%; with or without diabetes, obesity, or PAD; and without CLD. CONCLUSIONS: In patients undergoing CABG, MAG was associated with significantly improved survival in both sexes. The long-term benefits of MAG observed across subgroups of men and women support the consideration of a multiarterial revascularization strategy for a broader spectrum of patients.

Predictive role of monocyte count for significant coronary artery disease identification in patients with stable coronary artery disease.

BACKGROUND: The coronary artery disease (CAD) remains the leading cause of morbidity that is characterized by broad spectrum of symptoms. Up to 30% of performed angiographies reveal normal coronary arteries. The aim of the study was to find simple predictor for significant epicardial artery stenosis among patients with chronic coronary syndrome. METHODS: There were 187 patients (131 (709%) men and 56 (30%) women) in the median (Q1-Q3) age of 67 [58-72] presenting with stable CAD symptoms enrolled into the present retrospective analysis. The demographical, clinical and laboratory characteristics between patients with normal and significant coronary artery stenosis were compared. RESULTS: The multivariable analysis revealed coexistence of hypercholesterolemia as significant differentiation factor (odds ratio [OR]: 4.38, 95% confidence interval [CI]: 1.78-10.80, p = 0.001) for significant CAD and inverse relation to serum high density lipoprotein (OR: 0.19, 95% CI: 0.05-0.72, p = 0.015) and relation to creatinine concentration (OR: 1.03, 95% CI: 1.00-1.05, p = 0.012). Among whole peripheral blood count analysis, the significant relation was noticed to be hemoglobin concentration (OR: 1.09, 95% CI: 1.10-1.18, p = 0.022) and monocyte count (OR: 32.3, 95% CI: 1.09-653.6, p = 0.017). Receiver operator curve revealed (AUC: 0.641, p = 0.001) with the optimal cut-off value above 0.45 K/uL for monocyte, yelding sensitivity of 81.82% and specificity of 58.06%. CONCLUSIONS: The peripheral monocyte count above 0.45 k/uL may be considered as a predictor of significant coronary artery disease in symptomatic patients with chronic coronary syndrome.

The Diagnostic Value of Trace Metal Concentrations in Hair in Carotid Artery Disease.

Several studies showed the role of trace elements in the increase in human susceptibility to cardiovascular diseases. Carotid artery stenosis is a leading cause of ischemic neurological events. We aimed to analyze the potential role of trace elements in hair as biomarkers of atherosclerotic carotid artery disease. Materials and Methods: Fifty-seven (n = 31 (54%) men and n = 26 (46%) women) individuals with a mean age of 67.7 ± 7.7 years who were white, European, non-Hispanic, and non-Latino were diagnosed and treated in hypertensiology/internal medicine and surgical departments over three consecutive months. Of these patients, forty were diagnosed with advanced carotid artery disease, and seventeen comprised a group of healthy controls. Inflammatory and oncological diseases were exclusion criteria. Hair samples were collected, and 14 trace elements were analyzed. Clinical and laboratory data were compared and revealed differences in the co-existence of diabetes (p = 0.036) and smoking history (p = 0.041). In the multivariable analysis, zinc, chrome, and copper revealed predictive value for the occurrence of carotid artery disease, and their combined receiver operating curve showed area under the curve of 0.935, with a sensitivity of 95% and a specificity of 82.4%. Conclusion: Our report shows the significance of trace elements analyses in patients with advanced carotid artery disease. We revealed that zinc, copper, and chrome concentrations are of particular importance in differentiating atherosclerotic disease and may serve as biomarkers of carotid atherosclerosis. Hair samples represent an easily obtained and beneficial biomatrix for the assessment of biomarkers.

Do we correctly calculate doses of cardioplegia during aortic valve replacement procedures? A preliminary report.

Introduction: Intraoperative myocardial protection during aortic valve replacement (AVR) for aortic stenosis (AS) is of paramount importance for outcomes. The dose of cardioplegia is usually calculated with reference to body mass. Aim: To assess whether such a strategy should be applied to all AS patients undergoing AVR. Material and methods: The study included 94 patients who underwent elective isolated AVR in cardiopulmonary bypass with cold cardioplegic arrest, with a mean age of 65.4 ±7.8 years. They were divided into two subgroup: A with an infusion of high (above median) and subgroup B with a low (below median) volume of cardioplegia indexed for left ventricular mass (LVM). Their doses were referred to the maximal postoperative release of cardiac troponin I (cTnI max). Eventually, it was examined whether the extent of intraoperative myocardial injury translated into long-term survival stratified according to the Kaplan-Meier method. Results: The mean volume of cardioplegia was 1381 ±279 ml (4.9 ±1.6 ml/g of LV myocardium). cTnI max was much higher in group A than in group B (medians: 14.918 vs. 9.876 µg/l; p = 0.005). Moreover, a negative correlation between the index cardioplegia volume and cTnI max (r = 0.345) was noted. The five-year probability of survival in subgroup A (95.7%) was significantly better than that in subgroup B individuals (82.6%, p = 0.044). Conclusions: Calculating cardioplegic doses during AVR solely based on body mass may be suboptimal and have a significant impact on postoperative outcomes.

Long-term mortality after transcatheter aortic valve implantation for aortic stenosis in immunosuppression-treated patients: a propensity-matched multicentre retrospective registry-based analysis.

Introduction: Data regarding patients with a previous medical record of immunosuppression treatment who have undergone transcatheter aortic valve implantation (TAVI) are limited and extremely inconclusive. Available studies are mostly short term observations; thus there is a lack of evidence on efficacy and safety of TAVI in this specific group of patients. Aim: To compare the in-hospital and long-term outcomes between patients with or without a medical history of immunosuppressive treatment undergoing TAVI for aortic valve stenosis (AS). Material and methods: We conducted a retrospective registry-based analysis including patients undergoing TAVI for AS at 5 centres between January 2009 and August 2017. The primary endpoint was long-term all-cause mortality. Secondary endpoints comprised major vascular complications, life-threatening or disabling bleeding, stroke and new pacemaker implantation. Results: Of 1451 consecutive patients who underwent TAVI, two propensity-matched groups including 25 patients with a history of immunosuppression and 75 patients without it were analysed. No differences between groups in all-cause mortality were found in a median follow-up time of 2.7 years following TAVI (p = 0.465; HR = 0.73; 95% CI: 0.30-1.77). The rate of major vascular complications (4.0% vs. 5.3%) was similar in the two groups (p = 1.000). There were no statistically significant differences in the composite endpoint combining life-threatening or disabling bleeding, major vascular complications, stroke and new pacemaker implantation (40.0% vs. 20.0%, p = 0.218). Conclusions: Patients who had undergone TAVI for AS had similar long-term mortality regardless of whether they had a previous medical record of immunosuppression. Procedural complication rates were comparable between the groups.

Monocyte-to-lymphocyte ratio correlates with parathyroid hormone concentration in patients with severe symptomatic aortic stenosis.

PURPOSE: The normal healthy valve is devoid of inflammatory cells, however background of aortic stenosis (AS) may include inflammatory processes. Moreover, the link between hyperparathyroidism and heart failure is postulated. Simple whole blood analysis with indices is a beneficial tool in cardiovascular diseases' assessment. The purpose of the study was to evaluate correlation between parathyroid hormone (PTH) and simple blood parameters in severe AS. MATERIAL AND METHODS: The study included 62 patients with severe AS. Patients with inflammatory or autoimmune co-morbidities were excluded. Blood samples were collected, and clinical and demographic data were analyzed. RESULTS: The final study group comprised 55 patients (31 females, 56.4%; mean age 77.13 (SD 6.76)). In 23 patients (41.8%), PTH concentration was markedly increased. The study group was divided into two subgroups according to the PTH concentration. Patients from both groups did not differ significantly in terms of age and co-morbidities. PTH concentration correlated positively with monocyte-lymphocyte ratio (MLR) (p â€‹= â€‹0.008, Spearman rho 0.356) and platelet-lymphocyte ratio (PLR) (p â€‹= â€‹0.047, Spearman rho 0.269), creatinine level (p â€‹= â€‹0.001, Spearman rho 0.425) and glomerular filtration rate (GFR-MDRD) (p â€‹= â€‹0.009, Spearman rho -0.349). The multivariable logistic regression with backward analysis revealed MLR (p â€‹= â€‹0.029) and GFR (p â€‹= â€‹0.028) as independent significant predictors of abnormal PTH values. The receiver operator characteristics (ROC) curve was performed for the model of MLR and GFR-MDRD (AUC â€‹= â€‹0.777), yielding the sensitivity of 60.9% and specificity of 90.6%. CONCLUSIONS: PTH concentration correlates with monocyte-to-lymphocyte and platelet-to-lymphocyte ratios in calcified AS.

Long-Term Exposure of Nitrogen Oxides Air Pollution (NO2) Impact for Coronary Artery Lesion Progression-Pilot Study.

BACKGROUND: The potentially harmful effects of air pollution on the human health have been already presented in epidemiological studies, suggesting a strong association with increased morbidity and mortality. The aim of the study was to evaluate a possible relationship between coronary artery lesion progression related to habitation place (cities vs. villages) and air pollution. METHODS: There were 148 (101 men and 47 women) patients with a median age of 70 (63-74) years enrolled into retrospective analysis based on the coronary angiography results and their habitation place. Patients with stable coronary syndrome, who underwent repeated percutaneous coronary interventions were enrolled into the analysis based on demographical and clinical characteristics combined with annual exposure to air pollution (PM2.5, PM10, and NO2). RESULTS: The results of multivariable regression analysis showed a significant relationship between coronary artery lesion progression requiring percutaneous intervention and NO2 chronic exposure in patients living in cities of Poland (OR 2.00, 95% CI: 0.41-9.62, p < 0.001). The predictive value of air pollution exposure at habitation place for coronary artery lesion progression requiring percutaneous intervention was evaluated by receiver-operator curve analysis, which revealed an area under the curve of 0.939, yielding a sensitivity of 87.1% and specificity of 90.7%. CONCLUSIONS: Coronary artery lesion progression can be related to chronic exposure to NO2 air pollution in patients living in cities in Poland.

A comparative study of minimally invasive aortic valve replacement with sutureless biological versus mechanical prostheses.

Introduction: The ministernotomy approach with sutureless aortic bioprosthesis may provide an attractive and safe option for aortic valve disease patients. Aim: To assess the early and mid-term outcomes of minimally invasive aortic valve replacement (miniAVR) with sutureless vs. standard prostheses. Material and methods: The study involved 76 consecutive patients (51 males and 25 females) with mean age of 63.2 years who were treated with miniAVR between 2015 and 2022. They were divided into 2 subgroups: group I (n = 40) subjects with sutureless bioprostheses and group II (n = 36) with standard prostheses implanted. Early and mid-term outcomes were evaluated. A probability of survival was estimated by means of the Kaplan-Meier method. Results: No conversion to complete sternotomy was necessary. The median (minimum; maximum) aorta cross clamping and cardio-pulmonary bypass times were 49 (27; 84) and 70 (40; 188) minutes in group I whereas 69 (50; 103) and 95 (69; 170) minutes in group II, respectively (p < 0.001). In-hospital mortality was 5.0% (n = 2) and 2.8% (n = 1) in group I vs. II, respectively (ns). Permanent ICD implantation was performed in 8 (20.0%) in group I and in 3 (8.3%) subjects in group II. In the discharge echocardiography, the function of all prostheses was correct. Five-year probability of survival was much lower in group I (0.75 ±0.10) than in group II (0.94 ±0.04). No wound infection or sternum instability was noted. Conclusions: Intraoperative advantages of miniAVR procedures for aortic valve patients with sutureless bioprostheses do not translate directly into improved early and middle-term outcomes.

Predictive value of systemic inflammatory response index (SIRI) for complex coronary artery disease occurrence in patients presenting with angina equivalent symptoms.

BACKGROUND: Currently, atherosclerotic cardiovascular disease is the major cause of mortality world-wide. Inflammatory processes are postulated to be a major driving force for coronary plaque initiation and progression and can be evaluated by simple inflammatory markers from whole blood count analysis. Among hematological indexes, systemic inflammatory response index (SIRI) is defined as a quotient of neutrophils and monocytes, divided by lymphocyte count. The aim of the present retrospective analysis was to present the predictive role of SIRI for coronary artery disease (CAD) occurrence. METHODS: There were 256 patients (174 [68%] men and 82 [32%] women) in the median (Q1-Q3) age of 67 (58-72) years enrolled into retrospective analysis due to angina pectoris equivalent symptoms. A model for predicting CAD was created based on demographic data and blood cell parameters reflecting an inflammatory response. RESULTS: In patients with single/complex coronary disease the logistic regression multivariable analysis revealed predictive value of male gender (odds ratio [OR]: 3.98, 95% confidence interval [CI]: 1.38-11.42, p = 0.010), age (OR: 5.57, 95% CI: 0.83-0.98, p = 0.001), body mass index (OR: 0.89, 95% CI: 0.81-0.98, p = 0.012), and smoking (OR: 3.66, 95% CI: 1.71-18.22, p = 0.004). Among laboratory parameters, SIRI (OR: 5.52, 95% CI: 1.89-16.15, p = 0.029) and red blood cell distribution width (OR: 3.66, 95% CI: 1.67-8.04, p = 0.001) were found significant. CONCLUSIONS: Systemic inflammatory response index, a simple hematological index, may be helpful in patients with angina equivalent symptoms to diagnose CAD. Patients presenting with SIRI above 1.22 (area under the curve: 0.725, p < 0.001) have a higher probability of single and complex coronary disease.

Coronary Artery Bypass Surgery: Comparing the Long-Term Impact of Total Arterial Grafting With Multiarterial Plus Saphenous Vein Grafting.

INTRODUCTION: This study aimed to compare the long-term outcomes in a propensity matched population receiving total arterial grafting (TAG) and multiple arterial grafts (MAG) in addition to saphenous vein graft (SVG) following multivessel coronary artery bypass grafting requiring at least three distal anastomoses. METHODS: In this retrospective study, 655 patients from two centers met the inclusion criteria and were divided into two groups: TAG group (n = 231) and MAG + SVG group (n = 424). Propensity score matching was performed resulting in 231 pairs. RESULTS: No significant differences were observed between both groups in terms of early outcomes. Survival probabilities at 5, 10, and 15 y were 89.1% versus 94.2%, 76.2% versus 76.1%, and 66.7% versus 69.8% in the TAG and MAG + SVG groups, respectively (hazard ratio stratified on matched pairs: 0.90; 95% confidence interval [0.45-1.77]; P = 0.754). Freedom from major adverse cardiac and cerebral events (MACCE) in the matched cohort did not show any significant difference between both groups. Probabilities at 5, 10, and 15 y were 82.7% versus 85.6%, 62.2% versus 75.3%, and 48.8% versus 59.5% in the TAG and MAG + SVG groups, respectively (hazard ratio stratified on matched pairs: 1.12; 95% confidence interval [0.65-1.92]; P = 0.679). Subgroup analyses of the matched cohort showed no significant difference between TAR with three arterial conduits compared to TAR with two arterial conduits with sequential grafting and MAG + SVG in terms of long-term survival and freedom from MACCE. CONCLUSIONS: Multiple arterial revascularizations in addition to SVG may yield comparable long-term outcomes in terms of survival and freedom from MACCE compared to total arterial revascularization.
