RESUMEN
Valvular disease is a complex pathological condition that impacts countless individuals around the globe. Due to limited treatments, it is crucial to understand its mechanisms to identify new targets. Valve disease may result in pulmonary venous hypertension, which is linked to compromised functioning of the alveolar and capillary membranes and hindered gas exchange. Nonetheless, the correlation between surfactant proteins (SPs) and valve disease remains unexplored. A total of 44 patients were enrolled in this study, with 36 undergoing aortic valve replacement and 8 needing a second aortic valve substitution due to bioprosthetic valve degeneration. Ten healthy subjects were also included. The results showed that patients who underwent both the first valve replacement and the second surgery had significantly higher levels of immature SP-B (proSP-B) compared to control subjects. The levels of the extra-lung collectin SP-D were higher in patients who needed a second surgery due to bioprosthetic valve degeneration, while SP-A levels remained unchanged. The research also showed that there was no reciprocal relationship between inflammation and SP-D as the levels of inflammatory mediators did not differ between groups. The present study demonstrates that circulating proSP-B serves as a reliable marker of alveolar-capillary membrane damage in patients with valvular heart disease.

OBJECTIVES: The aim of this study was to investigate the need for postoperative permanent pacemaker implantation (PPI) following sutureless and rapid-deployment aortic valve replacement (SuRD-AVR) in the context of a progress report from a large multicenter international registry (SURD-IR). METHODS: We retrospectively analyzed 4,166 patients who underwent SuRD-AVR between 2008 and 2019. The primary outcome was the need for PPI before discharge. The study population was analyzed separately according to the implanted prostheses (Su cohort and RD cohort). Each cohort was divided into two groups based on the operation date: an early group ("EG" = 2008-2016) and a late group ("LG" = 2017-2019). RESULTS: The rate of PPI decreased significantly in the Su cohort over time (EG = 10.8% vs LG = 6.3%, p < 0.001). In the Su cohort, a decrease in age, risk profile, and incidence of bicuspid aortic valve, increased use of anterior right thoracotomy, reduction of cardiopulmonary bypass time and of associated procedures, and more frequent use of smaller prostheses were observed over time. In the RD cohort, the rate of PPI was stable over time (EG = 8.8% vs LG = 9.3%, p = 0.8). In this cohort, a younger age, lower risk profile, and higher incidence of concomitant septal myectomy were observed over time. CONCLUSION: Our analysis showed a significant decrease in the PPI rate in patients who underwent Su-AVR over time. Patient selection as well as surgical improvements and a more accurate sizing could be correlated with this phenomenon. The RD cohort revealed no significant differences either in patient's characteristics or in PPI rate between the two time periods.

BACKGROUND: This case represents the first report of malignant primary cardiac tumour in a patient with Lynch Syndrome associated with MSH2 pathogenic variant. CASE PRESENTATION: A 57-year-old woman with previous ovarian cystadenocarcinoma was admitted to the emergency room for hematic pericardial effusion. Multimodal diagnostic imaging revealed two solid pericardial vascularized masses. After pericardiectomy, the final histological diagnosis was poorly differentiated pleomorphic sarcomatoid carcinoma. During follow-up she developed an ampulla of Vater adenocarcinoma. Genetic analysis identified an MSH2 pathogenic variant. CONCLUSION: This case contributes to expand the tumour spectrum of Lynch syndrome, suggesting that MSH2 pathogenic variants cause a more complex multi-tumour cancer syndrome than the classic Lynch Syndrome. In MSH2 variant carriers, symptoms such as dyspnoea and chest discomfort might alert for rare tumours and a focused cardiac evaluation should be considered.

BACKGROUND: Purulent pericarditis is an infectious disease, frequently caused by gram-positive bacteria, that is rarely observed in healthy individuals, and is often associated with predisposing conditions. CASE PRESENTATION: Here, we present the case of an Escherichia coli post-surgical localized purulent pericarditis complicated by transient constrictive pericarditis and its diagnostic and therapeutic management. CONCLUSIONS: Our case report focuses on the importance of imaging-guided treatment of purulent pericardial diseases, in particular on the emerging role of 18 F-labelled 2-fluoro-2-deoxy-D-glucose Positron Emission Tomography/Computed Tomography in pericardial diseases and on the management of transient constrictive pericarditis, often seen after thoracic surgery.

The presence of a coronary arteriovenous fistula is almost rare in the adult population, even rare when associated with aortic valve insufficiency. Management and treatment options can vary and depend on a single patient. In our case, a large fistula with a rounded origin started from the roof of the left main stem, just attached to the wall of the aortic root, and finished with a very narrowed end in the pulmonary trunk. Due to its anatomical position and to the potential complications related to a proximal surgical closure as well as the incidental discovery in adult age (without signs or symptoms until the operation), we decided to have a conservative approach, leaving untouched the fistula. No intraoperative, perioperative, and follow-up signs of myocardial ischemia were observed.

An anomalous origin of the left circumflex coronary artery that arises as a side branch of the right coronary artery and encircles the aortic annulus is usually an incidental finding. However, in patients undergoing aortic valve/root procedures, its existence can significantly complicate the surgical treatment. We report our operative strategy with three different prostheses without valve downsizing.

BACKGROUND: Leiomyosarcoma of vascular origin is a rare tumor, occurring mainly in the inferior vena cava (IVC). When involving the hepatic vein confluence, it often causes Budd-Chiari syndrome, and IVC removal with a complex hepatectomy is required (Mingoli in J Am Coll Surg 211:145-146, 2010; Griffin in J Surg Oncol 34:53-60, 1987; Heaney in Ann Surg 163:237-241, 1966; Fortner in Ann Surg 180:644-652, 1974). METHODS: A 57-year-old male, without previous oncological history, presented with Budd-Chiari syndrome due to a leiomyosarcoma extending to the supra-diaphragmatic IVC and involving the right and middle hepatic veins. The patient did not receive neoadjuvant treatment. RESULTS: A femoral to superior vena cava veno-venous bypass was inserted, and both a median sternotomy and phreno-laparotomy with right subcostal extension were performed. A hemi-portocaval shunt was created between the right portal branch and the IVC, while a catheter was connected to the left portal branch for cold perfusion. Under extracorporeal circulation, the IVC was sectioned after infrahepatic and supra-diaphragmatic cross-clamping. The left liver was flushed with Celsior solution and packed with ice. A right trisectionectomy extended to the caudate lobe with en bloc vena cava removal was performed. The IVC was replaced by a cryopreserved aortic homograft, to which the stump of the left hepatic vein was anastomosed. Bypass duration, warm and cold liver ischemia, and operation time were 280 min, 8 min, 112 min, and 11 h, respectively. Duct-to-duct biliary anastomosis tutored by a T-tube was performed, and the patient was discharged on postoperative day 29, without major complications. After 16 months free of disease, the patient developed bilateral lung metastases. After 4 years the patient is still alive and receiving systemic chemotherapy. CONCLUSIONS: Leiomyosarcoma of the IVC involving the hepatic veins can be treated with extended hepatectomy and removal of the IVC through extracorporeal circulation.

OBJECTIVES: To compare the outcomes of trans-subclavian (TS) and transapical (TA) access for transcatheter aortic valve implantation (TAVI). BACKGROUND: A considerable proportion of patients undergoing TAVI are not eligible for transfemoral approach. To date, there are few data to guide the choice between alternative vascular access routes. METHODS: Among 874 consecutive patients who underwent TAVI, 202 procedures were performed through TA (n = 142, 70.3%) or TS (n = 60, 29.7%) access. Medtronic Corevalve (CV, Medtronic, Minneapolis, MN) was implanted in 17.3% of the patients, the Edwards-Sapien (ES, Edwards Lifesciences Inc., Irvine, CA) in 81.2% and other prostheses in 0.1%. In-hospital and long-term outcome were assessed using the Valve Academic Research Consortium (VARC)-2 definitions. RESULTS: Mean age was 82 ± 6 years, STS score 9.3 ± 7.9%. The 2 groups showed a relevant imbalance in baseline characteristics. In hospital mortality was 6.4% (1.7% TS vs. 8.4% TA, P = 0.06), stroke 2.0%, acute myocardial infarction 1.0%, acute kidney injury 39.4%, sepsis 4.0% with no significant differences between groups, while bleeding was more frequent in TA patients (53.5% vs. 11.7% TS, P < 0.001). One- and 2-year survival was 85.2% and 73.2% in TS patients, and 83.9% and 74.9% in TA patients (P = ns for both). Access site was not an independent predictor of mortality at multivariable analysis. CONCLUSION: Transapical compared with trans-subclavian access for TAVI was associated with a nonsignificant trend to increased periprocedural events. However, 1- and 2-year survival appears similar.

BACKGROUND: The study aim was to compare the outcome of transapical transcatheter aortic valve replacement (TaTAVR) and traditional aortic valve replacement (AVR) in redo from two real-world registries. METHODS: The 30-day and follow up outcome of 462 patients enrolled in two multicenter redo registries, treated with redo-AVR (RAVR; n = 292 patients) or TaTAVR (n = 170 patients), were analyzed according to VARC-2 criteria, stratified also by propensity-matching analysis. RESULTS: TaTAVR-patients were older and sicker than RAVR patients, and reported a higher all-cause 30-day mortality (p <0.01), a higher risk for all-cause mortality (p = 0.006) and cardiovascular mortality (p = 0.05) at follow up, but similar 30-day cardiovascular mortality (p = 0.12). Prolonged intubation (p <0.01) and Acute Kidney Injury Network (AKIN) 2/3 p = 0.02) prevailed in RAVR. TaTAVR patients reported a higher level of major/life-threatening/disabling bleeding (p <0.01) and 'early safety-events' (ES) (p = 0.04). Thirty-day acute myocardial infarction (AMI), stroke, and follow up freedom from acute heart failure (AHF), from stroke and from reinterventions were similar (p = NS). The NYHA class was better after RAVR (p <0.01). The intermediate-to-high risk (Logistic EuroSCORE RAVR 17.1 ± 8.5; TaTAVR 16.0 ± 17.0) propensity-matched population demonstrated comparable 30-day and follow up all-cause and cardiovascular mortality, ES, AMI, stroke, prolonged intubation, follow up freedom from AHF, from stroke and from reinterventions and NYHA class. TaTAVR still reported lower levels of AKIN 2/3 (2.2% versus 15.6%, p = 0.03) and shorter hospitalization (9.5 ± 3.4 days versus 12.0 ± 7.0 days, p = 0.03). CONCLUSIONS: Outcome differences between RAVR and TaTAVR in redo-scenarios reflect methodological differences and different baseline risk profiles. Propensity-matched patients showed a better renal outcome after TaTAVR. *Drs. Onorati and D'Onofrio contributed equally to this article and should both be considered as first authors.
RESUMEN
Iatrogenic injuries to the circumflex coronary artery during mitral valve surgery are probably underestimated (reported rates of 0.3-1.8%). This complication arises from the artery's close proximity to the mitral annulus, particularly at the anterolateral commissure. The study aimed to assess this risk in a patient group prone to such injury. The surgical procedure utilized a minimally invasive approach and indocyanine green-based fluorescence imaging. This technique allows a real-time visualization of the circumflex artery, aiding precise placement of annular sutures and minimizing the risk of injury. The method, applied in 6 patients, integrates preoperative assessments with intraoperative fluorescence imaging, ensuring accurate arterial depiction and preventing iatrogenic damage. The study highlights the safety and efficacy of fluorescence imaging, especially in identifying vessel anomalies, indicating potential applications in various cardiac procedures.

Surgical mitral valve repair (SMVR) is performed with various techniques that involve the implantation of non-biological material, such as the prolene of the suture threads, the polytetrafluoroethylene of the neo-chordae or the prosthetic ring for the remodeling of the valve annulus, whose exposure to the bloodstream is capable of triggering the blood coagulation cascade and consequently the development of thrombotic/thromboembolic events. The indications of the literature on the use of antithrombotic drugs after SMVR are weak and not univocal given the absence of randomized data and the availability of only small observational case series, which are generally contaminated by the lack of homogeneity of the populations examined. Indeed in these studies, patients not only undergoing SMVR, but also transcatheter repair of the mitral valve or surgical implantation of a biological valve prosthesis (not only in the mitral position) are included. In addition, the indication for antithrombotic therapy, and in particular anticoagulation, is often conditioned by the concomitant presence of atrial fibrillation that either preexists or develops postoperatively. In this review, the current evidence regarding antithrombotic therapy in patients undergoing SMVR, both in the presence or absence of atrial fibrillation, is summarized and updated treatment algorithms are proposed.

BACKGROUND: The benefits of mitral repair versus replacement for endocarditis are inconclusive. This study compares outcomes of patients with infective endocarditis undergoing mitral valve repair versus replacement and investigates the impact of microbial etiology. METHODS: All 251 patients undergoing mitral valve surgery for active endocarditis between 2010 and 2023 were enrolled, 180 (71.7%) replacement and 71 (28.3%) repair. To adjust for imbalances, inverse probability of treatment weighting was applied and 187 patients were obtained. RESULTS: The analysis between groups, following the application of inverse probability of treatment weighting, showed no statistically significant differences across all considered outcomes. Early and late death was observed respectively in 6 (8.5%) and 11 (15.5%) patients in the repair group versus 24 (13.3%) and 45 (25.0%) in the replacement group without statistical significance (p = 0.221 and p = 0.446). Relapse occurred in six patients (8.5%) in the repair group after a median time of 4.0 months and in six (3.3%) in the replacement after 6.9 months (p = 0.071). CONCLUSIONS: Surgical strategy in mitral endocarditis has no effect on major postoperative complications, mortality, or medium/long-term survival. Staphylococcus aureus and Coagulase-negative Staphylococci represent a risk for early mortality and relapse. However, mitral valve repair for endocarditis can be pursued when it ensures the complete eradication of all infected tissue, particularly in cases caused by Streptococcus infection, in young patients, and after a minimum of 18 days of antibiotic therapy.
RESUMEN
BACKGROUND: Bradyarrhythmia requiring pacemaker implantation among patients undergoing valve surgery may occur even after several years, with unclear predictors. Our aim was to investigate the incidence of pacemaker implantation at different follow-up times and identify associated predictors. METHODS: We conducted a retrospective study evaluating 1046 consecutive patients who underwent valve surgery at the Cardiac Surgery Division of Bologna University Hospital from 2005 to 2010. RESULTS: During 10 ± 4 years of follow-up, 11.4% of these patients required pacemaker implantation. Interventions on both atrioventricular valves independently predicted long-term pacemaker implantation (SHR 2.1, 95% CI 1.2-3.8, p = 0.014). Preoperative atrioventricular conduction disease strongly predicted long-term atrioventricular block, with right bundle branch block as the major predictor (SHR 7.0, 95% CI 3.9-12.4, p < 0.001), followed by left bundle branch block (SHR 4.9, 95% CI 2.4-10.1, p < 0.001), and left anterior fascicular block (SHR 3.9, 95% CI 1.8-8.3, p < 0.001). CONCLUSION: Patients undergoing valvular surgery have a continuing risk of atrioventricular block late after surgery until the 12-month follow-up, which was clearly superior to the rate of atrioventricular block observed at long-term. Pre-operative atrioventricular conduction disease and combined surgery on both atrioventricular valves are strong predictors of atrioventricular block requiring pacemaker implantation.
RESUMEN
BACKGROUND: Despite advanced diagnosis and treatment, infective endocarditis (IE) is a potentially life-threatening condition. The impact of COVID-19 on the diagnosis and outcome of the surgical treatment of IE is uncertain. The aim of this study was to analyze the incidence, characteristics, and outcomes of surgically treated IE before and after the COVID-19 pandemic. METHODS: This study retrospectively analyzed the data of 535 patients who underwent valve surgical procedures for IE between January 2010 and December 2022 in a single cardiac surgery center. Patients were divided into two groups depending on the date of their operation: before (n = 393) and after (n = 142) COVID-19 onset. In order to balance the groups, inverse probability of treatment weighting (IPTW) calculated from the propensity score (PS) was applied. Weighted univariate logistic regressions were reported for outcomes; weights were derived from IPTW. Interrupted time series analysis (ITSA) according to Linden's method was used to evaluate the changes in the manifestation of IE after 11 March 2020. RESULTS: Patients from the post-COVID-19 cohort (after 11 March 2020) had a greater number of comorbidities such as diabetes (29.6% vs. 16.3% p = 0.001), hypertension (71.1% vs. 59.5% p = 0.015), and preoperative kidney injury requiring dialysis (9.2% vs. 2.5% p = 0.002), but the median additive and logistic EuroSCORE were not statistically different. In the post-COVID-19 group, we observed a greater prevalence of Staphylococcus aureus-related endocarditis (24.5% vs. 15.4% p = 0.026), a consequent reduction in Staphylococcus non aureus-related endocarditis (12.2% vs. 20.1% p = 0.048), and a decrease in aortic valve replacements (43.0% vs. 53.9%), while the number of mitral valve replacements and repair was greater (21.1% vs. 15.0% and 6.3% vs. 4.3%, respectively). No differences were found in the two groups concerning early death, death, or relapse at 1 year after surgery. Data obtained by multivariable analysis identified preoperative renal dysfunction requiring dialysis as the only common risk factor for early mortality via stratifying by time periods in analysis. CONCLUSIONS: The incidence of surgically treated IE significantly increases after the COVID-19 pandemic with a higher incidence of mitral valve involvement with respect to the aortic valve. Although a delay in surgical timing occurred during the COVID-19 pandemic, data in terms of mortality and outcomes were largely unaffected.
RESUMEN
OBJECTIVES: In the last decades, 4 different scores for the prediction of mortality following surgery for type A acute aortic dissection (TAAD) were proposed. We aimed to validate these scores in a large external multicentre cohort. METHODS: We retrospectively analysed patients who underwent surgery for TAAD between 2000 and 2020. Patients were enrolled from 10 centres from 2 European countries. Outcomes were the early (30-day and/or in-hospital) and 1-year mortality. Discrimination, calibration and observed/expected (O/E) ratio were evaluated. RESULTS: A total of 1895 patients (31.7% females, mean age 63.72 ± 12.8 years) were included in the study. Thirty-day mortality and in-hospital mortality were 21.7% (n = 412) and 22.5% (n = 427) respectively. The German Registry of Acute Aortic Dissection Type A (GERAADA) score shows to have the best discrimination [area under the curve (AUC) 0.671 and 0.672] in predicting as well the early and the 1-year mortality, followed by the International Registry of Acute Aortic Dissection (IRAD) model 1 (AUC 0.658 and 0.672), the Centofanti (AUC 0.645 and 0.66) and the UK aortic score (AUC 0.549 and 0.563). According to Hosmer-Lemeshow and Brier tests, the IRAD model I and GERAADA, respectively, were well calibrated for the early mortality, while the GERAADA and Centofanti for the 1-year mortality. The O/E analysis showed a marked underestimation for patients labelled as low-risk for UK aortic score and IRAD model I for both outcomes. CONCLUSIONS: The GERAADA score showed the best performance in comparison with other scores. However, none of them achieved together a fair discrimination and a good calibration for predicting either the early or the 1-year mortality.

BACKGROUND: Although some trials have reported that on-pump coronary artery bypass graft (CABG) surgery may be associated with higher rates of stroke than percutaneous coronary intervention (PCI), whether stroke is more common after off-pump CABG compared with PCI is unknown. We therefore sought to determine whether off-pump CABG is associated with an increased risk of stroke compared with PCI by means of network meta-analysis. METHODS: Randomized controlled trials (RCTs) comparing CABG vs PCI were searched through MEDLINE, EMBASE, Cochrane databases, and proceedings of international meetings. RESULTS: Eighty-three RCTs with 22,729 patients randomized to on-pump CABG (n = 10,957), off-pump CABG (n = 7,119), or PCI (n = 4,653) were analyzed. Thirty-day rates of stroke were significantly lower in patients treated with PCI compared with either off-pump CABG (odds ratio [OR]; 0.39, 95% CI, 0.19-0.83) or on-pump CABG (OR, 0.26; 95% CI, 0.12-0.47). Compared with on-pump CABG, off-pump CABG was associated with significantly lower 30-day risk of stroke (OR, 0.67; 95% CI, 0.41-0.95). However, in sensitivity analyses restricted to high-quality studies, studies with more than either 100 or 1,000 patients, or studies with protocol definition or adjudication of stroke by a clinical events committee, the precision of the point estimate for the 30-day risk of stroke between off-pump vs on-pump CABG was markedly reduced. CONCLUSIONS: Percutaneous coronary intervention is associated with lower 30-day rates of stroke than both off-pump and on-pump CABG. Further studies are required to determine whether the risk of stroke is reduced with off-pump CABG compared with on-pump CABG.

Currently, minimally invasive cardiac surgery (MICS) has been developing and has been largely approved for mitral valve surgery. The more development of MICS, the more the entire surgical setup needs to be appropriate. We developed a homemade tool for mitral annular sizing that is simple and fits the mini surgical access. It is a plastic-based foldable paper that can be easily inserted through the minithoracotomy, using a surgical forceps.

BACKGROUND: Nowadays, one of the main goals of aortic valve surgery is to reduce the biological impact, mortality, and complications. It is well-known that long operative times in terms of the extracorporeal circulation, but above all, of the aortic cross-clamp time (ACC), represent a risk factor for mortality in patients undergoing cardiac surgery. In order to shorten the aortic cross-clamp time, many technological improvements, such as sutureless prostheses, have been introduced, but their actual effectiveness has not been proven yet. The aim of this study was to assess the 30-day outcomes of patients undergoing aortic valve replacement surgery, focusing on the ACC length. METHODS: All 3139 patients undergoing aortic valve replacement between January 2013 and July 2022 at our institution were enrolled. The data were retrospectively collected and the baseline characteristics and intraoperative variables were recorded. In order to adjust the results according to the differences in the baseline characteristics, propensity score matching was performed and four groups of 351 patients were obtained based on the first, second, third, and fourth quartile of the ACC time. RESULTS: The patient population included 132 redo surgeries (9.4%) and 61 cases of active endocarditis (4.3%), with an overall median EuroSCORE II of 1.8 (IQR 1.2-3.1). An increase across the groups was observed in terms of the acute kidney failure (p < 0.001) incidence, the number of blood transfusions (p = 0.022), prolonged hospital stays (p < 0.001), the and respiratory failure (p < 0.001) incidence. A p of < 0.1 was found for the 30-day mortality (p = 0.079). The predictors of an early 30-day mortality were standard full sternotomy (OR 2.48, 95% CI 1.14-5.40, p = 0.022), EuroSCORE II (OR 1.10, 95% CI 1.05-1.16, p < 0.001), and a trend for a longer ACC time (Q4 vs. Q1: OR 2.62, 95% CI 0.89-7.68, p = 0.080). CONCLUSIONS: Shortening the operative times resulted in marked improvements of the patients' outcomes. The combined use of minimally invasive approaches and sutureless aortic valve prostheses allows for a lower 30-day events rate. New technologies should be assessed to obtain the best results with the least risk.
RESUMEN
In elderly patients undergoing cardiac surgery, extracorporeal circulation affects the incidence of post-operative delirium and cognitive impairment with an impact on quality of life and mortality. In this study, a new oxygenator system (RemoweLL 2) was tested against a conventional system to assess its efficacy in reducing the onset of postoperative delirium and cognitive dysfunction and the levels of serum inflammatory markers. A total of 154 patients (>65 y.o.) undergoing cardiopulmonary bypass (CPB) were enrolled and randomly assigned to oxygenator RemoweLL 2 (n = 81) or to gold standard device Inspire (n = 73) between September 2019 and March 2022. The aims of the study were to assess the incidence of delirium and the cognitive decline by neuropsychiatric tests and the MoCa test intra-hospital and at 6 months after CPB. Inflammation biomarkers in both groups were also evaluated. Before the CPB, the experimental groups were comparable for all variables. After CPB, the incidence of severe post-operative delirium showed a better trend (p = 0.093) in patients assigned to RemoweLL 2 (16.0%) versus Inspire (26.0%). Differences in enolase levels (p = 0.049), white blood cells (p = 0.006), and neutrophils (p = 0.003) in favor of RemoweLL 2 were also found. The use of novel and better construction technologies in CPB oxygenator devices results in measurable better neurocognitive and neurological outcomes in the elderly population undergoing CPB.
