- Abstract
Structural valve degeneration, valve thrombosis, or acute infective endocarditis may affect the postprocedural outcome of transcatheter aortic valve implanted (TAVI) prostheses. Data of patients who required late surgical explant of TAVI prostheses were obtained from 8 European centers. There were 13 patients who underwent surgical treatment for TAVI prosthesis failure after original admission due to prosthetic infective endocarditis in 6 patients, structural valve degeneration in 4, and valve thrombosis in 3. Hospital mortality was 15%, and survival at the 2-year follow-up was 71%. Abstract word count: 80., (Copyright © 2021 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
Background: Patients with liver cirrhosis (LC) undergoing cardiac surgery (CS) face perioperative high mortality and morbidity, but extensive studies on this topic are lacking., Methods: All adult patients with LC undergoing a CS procedure between 2000 and 2017 at 10 Italian Institutions were included in this retrospective cohort study. LC was classified according to preoperative Child-Turcotte-Pugh (CTP) score and Model for End-Stage Liver Disease (MELD) score. Early-term and medium-term outcomes analysis was performed in the overall population and according to CTP classes., Results: The study population included 144 patients (mean age 66 ± 9 years, 69% male). Ninety-eight, 20, and 26 patients were in CTP class A, in early CTP class B (MELD score <12), or advanced CTP class B (MELD score >12), respectively. The main LC etiologies were viral (43%) and alcoholic (36%). Liver-related clinical presentation (ascites, esophageal varices, and encephalopathy) and laboratory values (estimated glomerular filtration rate, serum albumin, and bilirubin, platelet count) significantly worsened across the CTP classes (P = .001). Coronary artery bypass grafting or valve surgery (87% bioprosthesis) were performed in 36% and 50%, respectively. Postoperative complications (especially acute kidney injury, liver complication, and length of stay) significantly worsened in advanced CTP class B (P = .001). Notably, observed mortality was 3-fold or 4-fold higher than the EuroSCORE (European System for Cardiac Operative Risk Evaluation) II-predicted mortality, in the overall population, and in the subgroups. At Kaplan-Meier analysis, 1-year and 5-year cumulative survival in the overall population was 82% ± 3% and 77% ± 4%, respectively. The 5-year survival in CTP class A, early CTP class B, and advanced CTP class B was 72% ± 5%, 68% ± 11%, and 61% ± 10%, respectively (P = .238)., Conclusions: CS outcomes in patients with LC are significantly affected in relation to the extent of preoperative liver dysfunction, but in early CTP classes, medium-term survival is acceptable. Further analysis are needed to better estimate the preoperative risk stratification of these patients., (Copyright © 2021 The Society of Thoracic Surgeons. Published by Elsevier Inc.

- Abstract
Background: There is high demand for minimally invasive mitral valve repair; however, it is unclear whether the minimally invasive approach provides the same performance as conventional sternotomy in a context of complex mitral valve disease. Here, we compared outcomes of minimally invasive and sternotomy procedures for bileaflet and Barlow's mitral valve disease., Methods: We performed a pooled meta-analysis of studies reporting early and late follow-up of mitral valve repair for complex mitral valve regurgitation. The primary outcome was moderate mitral valve regurgitation recurrence and need for reoperation. Secondary outcomes included operation time, reopening for bleeding, associated tricuspid procedures, failed repair, and inhospital mortality. Incidence rates were calculated for long-term follow-up. Effect estimates were calculated as incidence rates with 95% confidence intervals. When Kaplan-Meier curves were available, event rates were estimated from the curves with Plot Digitizer software; otherwise, reported event rates were used to calculate incidence rates., Results: Eighteen studies including 1905 patients (654 minimally invasive and 1251 sternotomy) with a mean follow-up of 51.6 months (range, 14 to 138) were meta-analyzed with a random model. There were no significant between-group differences in moderate mitral valve regurgitation recurrence and reoperation (minimally invasive vs sternotomy, 1.7% [95% confidence interval, 1.0% to 2.9%] vs 1.3% [95% confidence interval, 0.9% to 1.8%], P = .22). Patients in the minimally invasive group were exposed to significantly longer cross-clamp and cardiopulmonary bypass times (P < .01); however, there were no additional between-group differences in secondary outcomes., Conclusions: This meta-analysis has demonstrated that minimally invasive and sternotomy approaches produce comparable results for complex mitral valve repair., (Copyright © 2020 The Society of Thoracic Surgeons.

- Abstract
Background: Porcine and pericardial valves exhibited similar freedom from structural valve deterioration after aortic valve replacement. Limited data exist regarding their durability at long-term follow-up in the mitral position., Methods: A literature search was performed through online databases. Papers reporting freedom from tissue valve deterioration after mitral valve replacement with a follow-up longer than 5 years were retrieved. Four porcine valves (Carpentier-Edwards [Edwards Lifesciences, Irvine, CA] and Hancock, Hancock II, and Mosaic [Medtronic, Inc, Minneapolis, MN]) and 1 pericardial prosthesis (Carpentier-Edwards) were the objects of the study. The structural valve deterioration (SVD) rate per year was calculated for each type of prosthesis. Kaplan-Meier curves and log-rank test analysis were performed to compare the long-term durability of porcine and pericardial valves., Results: Forty full-text papers including more than 15,000 patients were considered for the meta-analysis. Porcine valves were generally implanted in younger patients in the first period after their introduction. The mean age of the patients receiving a mitral bioprosthesis increased from 50 to 70 years over the decades. In patients operated after 1980 who had similar mean age at the time of implant, freedom from SVD was higher in the group of porcine valves with Mosaic prosthesis, showing the lowest rate of SVD. Long-term survival was higher for Mosaic porcine and Carpentier pericardial valves., Conclusions: In surgical populations that underwent mitral valve replacement after 1980 with new generation tissue valves and similar mean age at the implant time, we found, at long-term follow-up, a higher freedom from SVD in the group of porcine prostheses., (Copyright © 2020 The Society of Thoracic Surgeons.

- Abstract
Background: Anemia is a risk factor for adverse events after cardiac operations. We evaluated the incremental value of preoperative anemia over the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II to predict hospital death after cardiac operations., Methods: Data for 4,594 consecutive adults (1,548 women [33.7%]), aged 67 ± 11 years, who underwent cardiac operations from January 2011 to July 2013 were extracted from the Regional Cardiac Surgery Registry of Puglia. The last preoperative hemoglobin value was used, according to World Health Organization criteria, to classify anemia as mild (hemoglobin 11.0 to 12.9 g/dL in men and 11.0 to 11.9 g/dL in women) in 1,021 patients (22.2%) and as moderate to severe (hemoglobin <11.0 g/dL) in 593 patients (12.9%). The EuroSCORE II was used to evaluate predicted hospital death after operations. Logistic regression analysis for in-hospital death was performed including EuroSCORE II risk factors and anemia, with model discrimination quantified by C statistic and risk classification by the use of net reclassification improvement (NRI)., Results: Overall expected and observed mortality rates were 4.4% and 5.9%. Anemia was significantly associated with a mortality rate of 3.4% in patients without anemia, 7.7% in mild anemia, and 15.7% in moderate to severe anemia (p < 0.001) and also at multivariate analysis correcting for EuroSCORE II (p < 0.001). When anemia was analyzed with EuroSCORE II, the model improved in discrimination (C statistic = 0.852 vs 0.860; p = 0.007) and reclassification (category free-NRI, 0.592; p < 0.001), preserving the calibration with good concordance between predicted probabilities and outcome., Conclusions: Preoperative anemia has strong association with operative death in cardiac surgical patients. Anemia provides significant incremental value over the EuroSCORE II and should be considered for assessment of cardiac surgical risk., (Copyright © 2014 The Society of Thoracic Surgeons.

- Abstract
Background: Antithrombin (AT) concentrations are reduced after cardiac surgery with cardiopulmonary bypass compared with the preoperative levels. Low postoperative AT is associated with worse short- and mid-term clinical outcomes. The aim of the study is to evaluate the effects of AT administration on activation of the coagulation and fibrinolytic systems, platelet function, and the inflammatory response in patients with low postoperative AT levels., Methods: Sixty patients with postoperative AT levels of less than 65% were randomly assigned to receive purified AT (5000 IU in three administrations) or placebo in the postoperative intensive care unit. Thirty patients with postoperative AT levels greater than 65% were observed as controls. Interleukin 6 (a marker of inflammation), prothrombin fragment 1-2 (a marker of thrombin generation), plasmin-antiplasmin complex (a marker of fibrinolysis), and platelet factor 4 (a marker of platelet activation) were measured at six different times., Results: Compared with the no AT group and control patients, patients receiving AT showed significantly higher AT values until 48 hours after the last administration. Analysis of variance for repeated measures showed a significant effect of study treatment in reducing prothrombin fragment 1-2 (p=0.009; interaction with time sample, p=0.006) and plasmin-antiplasmin complex (p<0.001; interaction with time sample, p<0.001) values but not interleukin 6 (p=0.877; interaction with time sample, p=0.521) and platelet factor 4 (p=0.913; interaction with time sample, p=0.543). No difference in chest tube drainage, reopening for bleeding, and blood transfusion was observed., Conclusions: Antithrombin administration in patients with low AT activity after surgery with cardiopulmonary bypass reduces postoperative thrombin generation and fibrinolysis with no effects on platelet activation and inflammatory response., (Copyright © 2014 The Society of Thoracic Surgeons.

- Abstract
Background: Surgery for acute aortic dissection (AAD) is frequently complicated by excessive postoperative bleeding and blood product transfusion. Blood flow through the nonendothelialized false lumen is a potential trigger for the activation of the hemostatic system; however, the physiopathology of the aortic dissection induced coagulopathy has never been precisely studied. The aim of the present study is the evaluation of the coagulation and fibrinolytic systems and platelet activation in patients undergoing surgery for AAD., Methods: Eighteen patients undergoing emergent surgery for Stanford type A AAD were enrolled in the study. The activation of the coagulation and fibrinolytic systems and platelet activation were evaluated at 6 different time points before, during, and after the operation, measuring prothrombin fragment 1.2 (F1.2), plasmin-antiplasmin complex, and platelet factor 4, respectively., Results: All measured biomarkers were increased before, during, and after the operations indicating a systemic activation of coagulation, fibrinolysis, and platelets. These changes were pronounced even preoperatively (T0), and soon after the beginning of cardiopulmonary bypass (T1) when the influence of hypothermia and prolonged cardiopulmonary bypass time were not yet involved. Time from symptom onset to intervention inversely correlated with preoperative F1.2 (r=-0.75; p=0.002) and plasmin-antiplasmin levels (r=-0.57; p=0.034)., Conclusions: Blood flow through the false lumen is a powerful activator of the hemostatic system even before the operation. This remarkable activation may influence postoperative outcome of AAD patients., (Copyright © 2011 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: We conducted a prospective study of the clinical outcomes and health-related quality of life after implantation of the CorCap support device (Acorn Cardiovascular Inc, St Paul, MN) for dilated cardiomyopathy., Methods: The criteria adopted for CorCap implantation were dilated cardiomyopathy (left ventricular [LV] end-diastolic diameter≥60 mm, LV ejection fraction≤0.30 and >0.10), and New York Heart Association functional class II or III despite maximal medical therapy. Echocardiographic follow-up and evaluation with the Short Form-36 questionnaire were performed., Results: Included were 39 patients: 5 in New York Heart Association class II and 32 in class III. At 13.3±2.5 months of follow-up, a statistically significant improvement was evident in mean LV volume (LV end-systolic volume from 202±94 to 138±72 ml. p=0.005) and systolic function (LV ejection fraction from 0.26±0.05 to 0.36±0.05, p<0.001). The mean LV sphericity index was significantly increased at the end of the follow-up (p=0.009). Ischemic etiology, diabetes, advanced age, and LV ejection fraction of less than 0.15 predicted lesser reversal of the LV alterations. Operative mortality was 5.1%. Cumulative follow-up mortality was 10.2%. The average Physical Health domain scores (Physical Functioning, Role Physical, General Health) were improved. Average Mental Health domain scores were also increased., Conclusions: The cardiac support device obtains reverse remodelling of the LV and is useful to improve the quality of life of patients with dilated cardiomyopathy and New York Heart Association class III symptoms of heart failure. The integration of different and complementary strategies (cardiac support device and resynchronization therapy) may represent the key to success for more complex patients, although further studies are required., (Copyright © 2011 The Society of Thoracic Surgeons.

- Abstract
Background: The optimal timing for coronary artery bypass grafting (CABG) in patients with recent acute myocardial infarction (AMI) is unclear. Cardiac troponin I (cTnI) is a widely accepted biomarker of myocardial damage. The objective of this study was to determine whether preoperative cTnI values could be used to determine risk stratification for CABG operations in patients with recent AMI., Methods: Evaluated were 184 patients who sustained an AMI within 21 days of undergoing nonurgent CABG operations. They were divided into two groups according to their preoperative cTnI values: 117 patients with cTnI of 0.15 ng/mL or less and 67 with cTnI exceeding 0.15 ng/mL. Associations between study variables and events were assessed with logistic regression modelling. Time from AMI to operation was evaluated to define preoperative cTnI variation., Results: Values of cTnI tended to decrease when the interval between AMI and the operation increased. Preoperative cTnI values were significantly associated with a higher incidence of major postoperative complications (low cardiac output syndrome, intraaortic balloon pump necessity, mechanical ventilation >72 hours, acute renal failure, in-hospital mortality). Perioperative myocardial damage was more pronounced in patients with cTnI exceeding 0.15 ng/mL. Multivariate analyses revealed cTnI exceeding 0.15 ng/mL was an independent predictor for 6-month mortality (odds ratio, 3.7; p = 0.043)., Conclusions: Preoperative cTnI exceeding 0.15 ng/mL in patients with recent AMI undergoing CABG is associated with higher postoperative myocardial damage and is a strong determinant of postoperative morbidity and mortality within the 6-month period., (2010 The Society of Thoracic Surgeons.

- Abstract
Background: To date, no study has tested the effect of different heparin dosages on the hemostatic changes during off-pump coronary artery bypass graft (OPCABG) surgery, and a wide variety of empirical anticoagulation protocols are being applied. We tested the effect of two different heparin dosages on the activation of the hemostatic system in patients undergoing OPCABG procedures., Methods: Forty-two patients eligible for OPCABG procedures were assigned in a randomized fashion to low-dose heparin (150 IU/kg) or high-dose heparin (300 IU/kg). Prothrombin fragment 1+2, plasmin/alpha(2)-plasmin inhibitor complex, D-dimer, soluble tissue factor, tissue factor pathway inhibitor, total thrombin activatable fibrinolysis inhibitor (TAFI), and activated TAFIa were assayed by specific enzyme-linked immunosorbent assays at six different timepoints, before, during, and after surgery. Platelet function was evaluated by means of an in vitro bleeding time test, platelet function analyzer-100., Results: The OPCABG surgery was accompanied by significant changes of all plasma biomarkers, indicative of systemic activation of coagulation and fibrinolysis. A significant increase in circulating TAFIa was detected perioperatively and postoperatively, and multiple regression analysis indicated that prothrombin F1+2 but not plasmin/alpha(2)-antiplasmin complex was independently associated with TAFIa level. Platelet function analyzer-100 values did not change significantly after OPCABG. All hemostatic changes were similar in the two heparin groups, even perioperatively, when the difference in anticoagulation was maximal., Conclusions: Both early and late hemostatic changes, including TAFI activation, are similarly affected in the low-dose and high-dose heparin groups, suggesting that the increase in heparin dosage is not accompanied by a better control of clotting activation during OPCABG surgery., (2010 The Society of Thoracic Surgeons.

- Abstract
Background: C-reactive protein (CRP) is a known risk factor for cardiovascular events in the healthy population and in patients with coronary artery disease. High CRP levels before cardiac surgery are associated with worse short-term outcome, but its role after discharge home remains unknown. The study objective was to evaluate the effect of CRP on short-term and mid-term outcome after cardiac surgery., Methods: From August 2000 to May 2004, values for preoperative CRP were available for 597 unselected patients undergoing cardiac operations. CRP was used to divide this cohort in two groups: a low inflammatory status (LHS) group of 354 patients with CRP of less than 0.5 mg/dL, and a high inflammatory status (HIS) group of 243 patients with a CRP of 0.5 mg/dL or more. Follow-up lasted a maximum of 3 years (median, 1.8 +/- 1.5 years) and was 92.6% complete., Results: In-hospital mortality was 8.2% in the HIS group and 3.4% in the LIS group (odds ratio [OR], 2.61; p = 0.02). Incidence of postoperative infections was 16.5% in the HIS group and 5.1% in the LIS group (OR, 3.25; p = 0.0001). Sternal wound infections were also more frequent in the HIS group (10.7% versus 2.8%; OR, 3.43; p = 0.002). During follow-up, the HIS group had worse survival (88.5% +/- 2.9% versus 91.9% +/- 2.5%; OR, 1.93; p = 0.05) and a higher need of hospitalization for cardiac-related causes (73.6% +/- 6% versus 86.5% +/- 3.2%; OR, 1.82; p = 0.05)., Conclusions: Patients undergoing cardiac surgery with a CRP level of 0.5 mg/dL or more are exposed to a higher risk of in-hospital mortality and postoperative infections. Despite surgical correction of cardiac disease, a high preoperative CRP value is an independent risk factor for mid-term survival and hospitalization for cardiac causes.

- Abstract
Background: Markers of myocardial necrosis are usually elevated in patients who have undergone a coronary bypass operation with cardiac arrest. The preferred marker in detecting acute myocardial ischemia is cardiac troponin I (cTnI). However, its ability to predict short-term and, particularly, midterm outcome after coronary bypass operations is uncertain., Methods: Two hundred thirty unselected patients undergoing surgical revascularization had cTnI measured preoperatively and 11 times postoperatively. Receiver operating characteristic curves were constructed using cTnI postoperative peak values in order to assess the prognostic sensitivity and specificity of the test. The cut-off value of 13 ng/mL was used to assess the prognostic significance of the peak cTnI postoperative release for short-term and midterm outcomes., Results: One hundred forty-six patients (63.5%) had postoperative cTnI peak values less than 13 ng/mL (mean peak value, 6.6 +/- 3.1 ng/mL) and 84 patients (36.5%) had postoperative cTnI peak values greater than 13 ng/mL (mean peak value, 45.5 +/- 59.9 ng/mL). Patients with peak cTnI greater than 13 ng/mL were older and had higher preoperative cTnI values. They required both longer cross-clamp time and CPB time. Moreover, hospital death in the cTnI greater than 13 ng/mL group (9.5% versus 0.7%, p = 0.0009) was significantly higher. Multivariate analysis showed that cTnI greater than 13 ng/mL was the only independent predictor of hospital death (odds ratio 10.33, p = 0.04) and hospital death from cardiac causes. A 2-year follow-up demonstrates that cTnI postoperative release had no influence on midterm mortality and hospitalization for due to cardiac illness., Conclusions: Cardiac troponin I is a valuable marker for immediate myocardial damage after coronary bypass operations. Its postoperative release does not predict midterm outcome.

- Abstract
Background: Patients undergoing bypass grafting (CABG) often present with mitral regurgitation (MR). While surgical strategy for patients with either trace or severe MR is well established, the need for a valve procedure with mild (2) to moderate (3+) mitral regurgitation is controversial., Methods: We reviewed 1,939 consecutive CABG patients (1987 to 1999). A preoperative echocardiogram performed when clinically indicated graded MR from 1 to 4+. Patient characteristics, hospital mortality, and long-term survival were compared between 167 patients with grade 2 to 3+ MR and controls. A multivariate analysis identified independent predictors for long-term mortality., Results: The MR patients were more often female and older; had increased comorbidities including hypertension, diabetes, and heart failure; had more extensive coronary disease and worse left ventricular (LV) function; and required urgent surgery more often. Operative mortality was 0.8% in no MR patients and 1.8% in MR patients (p not significant). Long-term survival for MR patients with poor LV function (LV grade 3 to 4) was significantly lower (53% versus 75% at 10 years, p = 0.001). Independent predictors of poor long-term survival were advanced age, LV dysfunction, heart failure, diabetes, prior cerebrovascular accident, peripheral vascular disease, and no left internal mammary artery use., Conclusions: Coronary artery bypass graft patients with mild or moderate MR have worse baseline characteristics but operative mortality with CABG alone is not significantly increased. Long-term prognosis for MR patients with poor LV function is worse compared with patients with no MR but MR was not an independent predictor of long-term mortality. To determine whether surgical correction of MR would improve results, a prospective randomized trial seems warranted.
