Salvage coronary artery bypass grafting (CABG) is often performed for cardiogenic shock on compassionate basis without clinical data justifying this aggressive approach. The aim of this study was to analyze early and intermediate outcomes after salvage CABG. We retrospectively reviewed the data of 85 patients who underwent salvage CABG at 11 European cardiac surgery centers. Salvage CABG was defined according to the EuroSCORE criteria, that is, a procedure performed in patients requiring cardiopulmonary resuscitation (external cardiac massage) en route to the operating theater or before induction of anesthesia. A percutaneous coronary intervention procedure preceded salvage CABG in 55 patients (64.7%). Thirty patients (35.3%) died during the inhospital stay. The mean EuroSCORE II was 32.0% and the observed-to-expected ratio was 1.08. Salvage CABG was associated with high rates of postoperative stroke (9.4%), resternotomy for bleeding (23.5%), resternotomy for hemodynamic instability (15.3%), dialysis (18.8%), severe gastrointestinal complications (12.9%), and deep sternal wound infection (10.6%). Survival at 1, 3, and 5 years was 58.6%, 49.8%, and 40.9%, respectively. Twenty patients (23.5%) were postoperatively treated with extracorporeal membrane oxygenation (ECMO). The rates of adverse events after ECMO were particularly high (stroke 40%, resternotomy for bleeding 60%, dialysis 35%, gastrointestinal complications 30%, and deep sternal wound infection 30%). Of patients treated with ECMO, 8 (40%) survived to discharge, and 1-year survival was 29.2%. Salvage CABG is associated with high risk of immediate mortality and severe adverse events. However, the observed immediate and intermediate outcome justify coronary surgery in these critically ill patients. A number of these patients are currently treated by ECMO, and its results are encouraging.

Background Clinical evidence in coronary surgery is usually derived from retrospective, single institutional series. This may introduce significant biases in the analysis of critical issues in the treatment of these patients. In order to avoid such methodological limitations, we planned a European multicenter, prospective study on coronary artery bypass grafting, the E-CABG registry. Design The E-CABG registry is a multicenter study and its data are prospectively collected from 13 centers of cardiac surgery in university and community hospitals located in six European countries (England, Italy, Finland, France, Germany, Sweden). Data on major and minor immediate postoperative adverse events will be collected. Data on late all-cause mortality, stroke, myocardial infarction and repeat revascularization will be collected during a 10-year follow-up period. These investigators provided a score from 0 to 10 for any major postoperative adverse events and their rounded medians were used to stratify the severity of these complications in four grades. The sum of these scores for each complication/intervention occurring after coronary artery bypass grafting will be used as an additive score for further stratification of the prognostic importance of these events. Discussion The E-CABG registry is expected to provide valuable data for identification of risk factors and treatment strategies associated with suboptimal outcome. These information may improve the safety and durability of coronary artery bypass grafting. The proposed classification of postoperative complications may become a valuable research tool to stratify the impact of such complications on the outcome of these patients and evaluate the burden of resources needed for their treatment.

The use of bilateral internal thoracic artery (BITA) grafting for myocardial revascularization is usually discouraged in the very elderly because of increased risk of perioperative complications. The aim of the study was to analyze early and late outcomes of BITA grafting in octogenarians. From January 1999 throughout February 2014, 236 consecutive octogenarians with multivessel coronary artery disease underwent primary isolated coronary bypass surgery at the authors’ institution. Six of these patients underwent emergency surgery and were excluded from this retrospective study; consequently, 135 BITA patients were compared with 95 single internal thoracic artery (SITA) patients according to early and late outcomes. Between BITA and SITA patients, there was no significant difference in the operative risk (EuroSCORE II: 8 ± 7.7 vs. 7.6 ± 6.1 %, p  = 0.65). There was a lower aortic manipulation in BITA patients. Hospital mortality (3 vs. 4.2 %, p  = 0.44) and perioperative complications were similar except that only BITA patients experienced sternal wound infection (5.2 %, p  = 0.022). The mean follow-up was 4.7 ± 3.3 years. There were no differences between the two groups in overall survival ( p  = 0.79), freedom from cardiac and cerebrovascular deaths ( p  = 0.73), major adverse cardiac and cerebrovascular events ( p  = 0.63) and heart failure hospital readmission ( p  = 0.64). Predictors of decreased late survival were diabetes ( p  = 0.0062) and congestive heart failure ( p  = 0.0004). BITA grafting can be routinely used in octogenarians with atherosclerotic ascending aorta without an increase in hospital mortality or major adverse cardiac and cerebrovascular complications. However, there is an increased risk of sternal wound infection without a demonstrable long-term benefit.

This study reports the determination of DNOC in the baits and gastric contents of poisoned dogs and wild canids collected in the Abruzzo region between 2014 and 2022. A total of 663 samples of the baits and carcasses of domestic and wild animals were analyzed for the determination of DNOC through GC-MS. DNOC was found to be present in 58 cases from 663 analyzed samples, with 49 poison baits and nine gastric content samples from dogs and red foxes. This study confirms for the first time that the banned pesticide DNOC still poisons both domestic and wild animals in the Abruzzo region. It should be considered that this study was carried out on a population of animals from a regional geographical area, and more detailed country-wide studies need to be carried out to obtain the incidence of poisoning from this herbicide in Italy. Furthermore, these findings emphasize the importance of considering this chemical in differential diagnosis during toxicological investigations of animal poisoning.

Perioperative bleeding is a determinant of poor outcome in patients undergoing coronary artery bypass grafting (CABG), but there is a lack of adequate stratification of its severity. The ability of the European registry of Coronary Artery Bypass Grafting (E-CABG), Universal Definition of Perioperative Bleeding (UDPB), Study of Platelet Inhibition and Patient Outcomes (PLATO), Clopidogrel and Aspirin Optimal Dose Usage to Reduce Recurrent Events−Seventh Organization to Assess Strategies in Ischemic Syndromes (CURRENT-OASIS 7), Efficacy and Safety of Subcutaneous Enoxaparin in Non-Q Wave Coronary Events (ESSENCE), and SafeTy and Efficacy of Enoxaparin in Percutaneous coronary intervention patients, an internationaL randomized Evaluation (STEEPLE) bleeding classifications to predict early mortality, stroke, acute kidney injury (AKI) stage 3, and deep sternal wound infection/mediastinitis was investigated in 3,730 patients from the prospective, multicentre E-CABG registry. Increasing grades of the E-CABG, UDPB, PLATO, and CURRENT-OASIS 7 classifications were associated with increasing risks of early mortality, had similar receiver-operating characteristic area under the curves (>0.7), and were predictive also when adjusted for EuroSCORE II. The E-CABG and UDPB classifications had satisfactory area under the curves (>0.6) in predicting stroke, AKI stage 3, and deep sternal wound infection/mediastinitis even when adjusted for EuroSCORE II. The PLATO and CURRENT-OASIS 7 classifications had similar predictive ability for stroke and AKI stage 3 as confirmed by multivariate analysis adjusted for EuroSCORE II but showed inferior ability in predicting severe wound infection compared to the E-CABG and UDPB classifications. The STEEPLE and ESSENCE classifications had a poor ability of predicting all these adverse events. Decision curve analysis showed a benefit of the E-CABG bleeding classification over the other classifications in predicting all adverse events. In conclusion, the E-CABG, UDPB, PLATO, and CURRENT-OASIS 7 bleeding classifications have a satisfactory ability in predicting adverse events after CABG. Decision curve analysis showed that the E-CABG bleeding classification had the best predictive performance.

Left-sided coronary revascularization with bilateral internal thoracic artery (BITA) graft is performed usually either with an in situ (double source) or Y-graft configuration (single source). Two hundred fifty-three (mean age, 67.1 ± 9.5 years) patients underwent isolated left-sided coronary revascularization with BITA graft alone at the present authors’ institution (2000–2015). Skeletonized BITA grafts were used either in an in situ (n = 199) or Y-graft configuration (n = 54). Forty pairs were identified with the propensity score-matching. Outcomes of the two groups were compared both in unmatched and matched series. Cardiopulmonary exercise testing was performed in five pairs of selected, asymptomatic matched patients having patent BITA grafts at coronary computed tomography angiography. BITA in situ patients had lower risk profiles than BITA Y-graft patients (median EuroSCORE II, 1.9 vs. 2.9%, p = 0.051). In-hospital mortality (5.6 vs. 0, p = 0.0093) and the rates of postoperative complications except deep sternal wound infection were higher in BITA Y-graft patients. However, these differences were not confirmed in matched groups. During the follow-up period (mean, 5.9 ± 4.3 years), between BITA in situ and BITA Y-graft matched patients, there were no differences in non-parametric estimates of freedom from cardiac death (p = 0.6), major adverse cardiac and cerebrovascular events (MACCEs, p = 0.65), and repeat coronary revascularization (p = 0.44). Adjusted risk estimates of MACCEs according to BITA configuration confirmed no superiority of the one configuration over the other (p ≥ 0.44). No significant differences were found at the cardiopulmonary exercise testing. Results of left-sided coronary revascularization with BITA graft alone are independent from BITA configuration, even after stress testing.

The aim of this study was to compare the immediate outcome of patients undergoing transcatheter (TAVI) versus surgical aortic valve replacement with the sutureless Perceval bioprosthesis (SU-AVR). This is a retrospective multicenter analysis of 773 patients who underwent either TAVI (394 patients, mean age, 80.8 ± 5.5 years, mean EuroSCORE II 5.6 ± 4.9 %) or SU-AVR (379 patients, 77.4 ± 5.4 years, mean EuroSCORE II 4.0 ± 3.9 %) with or without concomitant myocardial revascularization. Data on SU-AVRs were provided by six European institutions (Belgium, Finland, Germany, Italy and Sweden) and data on TAVIs were provided by a single institution (Catania, Italy). In-hospital mortality was 2.6 % after SU-AVR and 5.3 % after TAVI ( p  = 0.057). TAVI was associated with a significantly high rate of mild (44.0 vs. 2.1 %) and moderate–severe paravalvular regurgitation (14.1 vs. 0.3 %, p  < 0.0001) as well as the need for permanent pacemaker implantation (17.3 vs. 9.8 %, p  = 0.003) compared with SU-AVR. The analysis of patients within the 25th and 75th percentiles interval of EuroSCORE II, i.e., 2.1–5.8 %, confirmed the findings of the overall series. One-to-one propensity score-matched analysis resulted in 144 pairs with similar baseline characteristics and operative risk. Among these matched pairs, in-hospital mortality (6.9 vs. 1.4 %, p  = 0.035) was significantly higher after TAVI. SU-AVR with the Perceval prosthesis in intermediate-risk patients is associated with excellent immediate survival and is a valid alternative to TAVI in these patients.

Extensive surgical resection of the thoracic aorta in patients with type A aortic dissection (TAAD) is thought to reduce the risk of late aortic wall degeneration and the need for repeat aortic operations. We evaluated the early and late outcomes after aortic root replacement and supracoronary ascending aortic replacement in patients with TAAD involving the aortic root. Retrospective, multicenter cohort study. The outcomes after aortic root replacement and supracoronary ascending aortic replacement in patients with TAAD involving the aortic root, that is dissection flap located at least in one of the Valsava segments, were herein evaluated. In-hospital mortality, neurological complications, dialysis as well as 10-year repeat proximal aortic operation, and mortality were the outcomes of this study. Supracoronary ascending aortic replacement was performed in 198 patients and aortic root replacement in 215 patients. During a mean follow-up of 4.0 ± 4.0 years, 19 patients underwent 22 repeat procedures on the aortic root and/or aortic valve. No operative death occurred after these reinterventions. The risk of proximal aortic reoperation was significantly lower in patients who underwent aortic root replacement (5.5% vs 12.9%, adjusted subdistributional hazard ratio (SHR) 0.085, 95% CI 0.022-0.329). Aortic root replacement was associated with higher rates of in-hospital (14.4% vs 12.1%, adjusted odds ratio 2.192, 95% CI 1.000-4.807) and 10-year mortality (44.5% vs 30.4%, adjusted hazard ratio 2.216, 95% CI 1.338-3.671). Postoperative neurological complications and dialysis rates were comparable in the study groups. Among patients with TAAD involving the aortic root, its replacement was associated with a significantly lower rate of repeat proximal aortic operation of any type compared to supracoronary aortic replacement. Still, aortic root replacement seems to be associated with an increased risk of mortality in these patients. ClinicalTrials.gov: NCT04831073 (https://clinicaltrials.gov/study/NCT04831073).

The aims of this study were to investigate the clinical outcomes of patients with low-gradient aortic stenosis despite preserved left ventricular ejection fraction and to assess reliable prognostic clinical-instrumental features in patients experiencing or not experiencing aortic valve replacement (AVR). Clinical-laboratory and echocardiographic data from 167 patients (median age 78 years, interquartile range 69 to 83) with aortic valve areas <1.0 cm2, mean gradients ≤30 mm Hg, and preserved left ventricular ejection fraction (≥55%), enrolled from 2005 to 2010, were analyzed. During a mean follow-up period of 44 ± 23 months, 33% of patients died. On multivariate analysis, independent predictors of death were baseline New York Heart Association functional class III or IV (hazard ratio 2.16, p = 0.038) and atrial fibrillation (hazard ratio 2.00, p = 0.025). Conversely, AVR was protective (hazard ratio 0.25, p = 0.01). The magnitude of the protective effect of AVR seemed to be relatively more important in patients with atrial fibrillation than in those in sinus rhythm, independently of the severity of symptoms. Age >70 years showed a trend toward being a prognostic predictor (p = 0.082). In conclusion, in patients with low-gradient aortic stenosis despite a preserved left ventricular ejection fraction, AVR was strongly correlated with a better prognosis. Patients with atrial fibrillation associated with advanced New York Heart Association class had the worst prognosis if treated medically but at the same time a relative better benefit from surgical intervention.

Background: Type A aortic dissection (TAAD) is a life-threatening condition which requires prompt diagnosis and surgical treatment. When TAAD involves the aortic root, aortic valve-sparing or Bentall procedures are the main surgical treatment options. Method: The subjects of this analysis were 3735 patients included in the European Registry of Type A Aortic Dissection (ERTAAD). Propensity score matching was performed by estimating a propensity score from being treated with the Bentall or the David procedure using multilevel mixed-effects logistics, considering the cluster effect of the participating hospitals. Results: A Bentall procedure was performed in 862 patients, while a David operation was performed in 139 patients. The proportion of aortic root replacement, as well as the different techniques of aortic root replacement, varied significantly between the participating hospitals (p < 0.001). After propensity score matching, we obtained two groups of 115 patients each, and no statistical differences were reported in terms of postoperative outcomes, except for the rate of dialysis, which was higher in the patients requiring a Bentall procedure (17.4% vs. 7.0%, p-value 0.016). In the unmatched cohorts, the David procedure was associated with a lower 10-year mortality rate compared to the Bentall procedure (30.1% vs. 45.6%, p-value 0.004), but no difference was observed after matching (30.0% vs. 43.9%, p-value 0.082). After 10 years, no differences were observed in terms of proximal aortic reoperation (3.9% vs. 4.1%, p-value 0.954), even after propensity score matching (2.8% vs. 1.8%, p-value 0.994). Conclusions: The David and Bentall procedures are durable treatment methods for TAAD. When feasible, it is advisable that the David procedure is performed for acute TAAD by surgeons with experience with this demanding surgical technique.
