ABSTRACT
Background: Abdominal aortic aneurysm (AAA) is a chronic inflammatory disease that poses several challenges. Given the increasing evidence that AAA patients are more likely to develop cancer and the importance of its early detection, we strived to develop a non-invasive tool based on serial FDG-PET/CT scan examinations to identify, among AAA patients, those at risk of cancer. Methods: Between 2006 and 2011 we recruited 149 AAA patients, free of cancer at baseline, and followed them until the end of 2021. All patients underwent an FDG-PET/CT scan at inclusion and possibly more scans during follow-up. At each medical imaging examination, the aneurysmal FDG uptake was recorded. Patients were stratified based on their aortic wall PET status (negative/positive). Any occurrence of cancer was reported. A Cox regression analysis and competing-risk modeling were applied to the data. Results: The proportion of AAA patients who developed cancer was 31.5% (mean time to diagnosis was 5.7 ± 3.4 years) and the death rate was 59%. A difference in cancer incidence between PET+ and PET- patients was detected (46.8% vs. 27.3%; HR = 1.96, 95%CI: 1.07-3.57, p = 0.028). Moreover, AAA patients undergoing surgical treatment had a lower risk of cancer than unoperated patients (28% vs. 50%; HR = 0.41, 95%CI: 0.21-0.80, p = 0.009). Conclusions: In AAA patients, diagnostic imaging with an FDG-PET/CT scan can help identify those patients at a higher risk of developing cancer. Moreover, the higher cancer risk in non-surgically treated patients calls for further analysis of associations between aneurysm growth and malignant disease.
ABSTRACT
Manual closure of the bronchial stump can be challenging during minimally invasive thoracic surgery. An automated fastener has been used for more than a decade in minimally invasive heart valve surgery to eliminate the need for manual knot tying during the suturing of prosthetic valves. Herein, we describe the use of the COR-KNOT automated fastener (LSI SOLUTIONS®, Victor, NY, USA) in a case of video-assisted left upper lobectomy with open section of the bronchus and manual closure with interrupted resorbable sutures for a malignant bronchial tumor located on the proximal part of the left upper lobe bronchus. This case represents, to our knowledge, the first case using the COR-KNOT device for minimally invasive pulmonary surgery.

In the past 20 years, there has been a real development of aortic valve repair techniques with an increasing number of publications describing the long-term benefits of aortic valve repair in terms of survival, freedom from major adverse valve related-events and reoperations. Aortic valve repair can now be considered as a valuable alternative to prosthetic valve replacement in patients with dystrophic ascending aorta pathology associated or not to aortic insufficiency with pliable leaflets. In this paper, the authors describe the state of the art of aortic valve repair and present their clinical experience with aortic valve repair surgery in the university hospital center of Liege from April 2021 to September 2022.
Les techniques de réparation de la valve aortique se sont considérablement développées ces 20 dernières années. Plusieurs publications confirment les bénéfices à long terme de ces techniques en termes de survie, d'absence de complications majeures et de réinterventions pour récidive d'insuffisance aortique. La réparation de la valve aortique apparaît ainsi comme une véritable alternative au remplacement valvulaire aortique prothétique chez certains patients qui présentent une pathologie dystrophique de l'aorte ascendante associée ou non à une insuffisance aortique sur valve souple. Dans cet article, les auteurs parcourent la littérature actuelle sur le sujet et décrivent leur expérience clinique avec la chirurgie de réparation de la valve aortique au sein du centre hospitalier universitaire de Liège d'avril 2021 à septembre 2022.

We present the case of a middle-aged man who developed infective endocarditis of the tricuspid valve caused by methicillin-sensitive Staphylococcus aureus and associated with very large vegetation (â¼5 cm). Besides the quite unusual size of the vegetation, this report highlights that severe right-sided endocarditis can occur in the absence of classical risk factors (intravenous drug abuse, presence of a cardiac implantable electronic device or other intravascular devices, and underlying right-sided cardiac anomaly) and that some cases of severe tricuspid endocarditis can be successfully treated by partial excision and patch repair.

BACKGROUND: Abdominal aortic aneurysm (AAA) rupture is a serious condition that results in extremely high mortality rates. Some improvements in outcome have been reported during the last 2 decades. The objective of the present study was to determine the overall and operative (by open repair) mortality related to ruptured AAA in the contemporary era and to identify preoperative, intraoperative, and early postoperative parameters associated with poor outcomes. METHODS: We performed a retrospective review of all consecutive patients admitted to our single institution with a diagnosis of ruptured AAA between 2004 and 2013. A total of 103 parameters, including demographic characteristics, medical history, clinical and biological parameters, cardiovascular risk factors, emergency level, diagnostic modalities, time from symptoms to diagnosis and treatment, type of operative procedure and postoperative complications, were analyzed. The primary endpoint considered in this study was the cumulative incidence rate of mortality. The secondary endpoint was the identification, by logistic regression methods, of risk factors for overall mortality as well as for operative, and postoperative mortality. RESULTS: Within our study period, 104 patients were admitted for a ruptured AAA. The majority of patients (84.6%) were male, and the AAA was known in 34.6% of the patients. Rupture occurred for a maximal diameter lower than 55 mm in 25% of the female population, compared to 5.7% of the male population (P = 0.030). The proportions of admitted patients who died before (preoperative mortality), during (intraoperative mortality) or after (postoperative hospital mortality) surgery was 17.3%, 16.3%, and 18.3%, respectively, yielding a cumulative in-hospital mortality of 51.9%. In the multivariate analysis, age ≥ 80 (P = 0.001), myocardial ischemia on the admission ECG (P = 0.046), and management by the physician response unit (P = 0.002) were the only preoperative parameters associated with a higher risk of hospital mortality. Four risk factors were found to be associated with a higher risk of postoperative mortality in the multivariate analysis, and all patients presenting with 3 or more of these risk factors (n = 5) died. CONCLUSIONS: The overall mortality of ruptured AAA in a contemporary cohort of patients who underwent open repair remains high and does not seem to have decreased during recent decades. Ruptures occur at smaller diameters in women than in men, supporting a lower threshold for intervention in women with known AAA. We developed risk scores to predict the mortality of patients with rAAA at different times of their hospital course. The validity of these scores should be assessed in prospective clinical studies.

OBJECTIVES: Circulating cardiac biomarkers may improve the prediction of long-term outcomes after cardiac surgery. The authors sought to assess if cardiac biomarkers also help better predict short-term morbidity. DESIGN: Prospective observational study. SETTING: Single academic hospital. PARTICIPANTS: A total of 250 patients undergoing aortic or mitral valve surgery with or without associated coronary artery bypass grafts. INTERVENTION: None MEASUREMENT AND MAIN RESULTS: Relationships between preoperative plasma concentrations of four cardiac biomarkers (sST2, Galectin-3, GDF-15, and NT-proBNP) and postoperative outcome were assessed using logistic regressions and Cox proportional hazards models. The primary outcome was a composite of 30-day mortality, an inotropic support longer than 48 hours and an initial length of stay in the intensive care >five days. Secondary outcome measures were postoperative acute kidney injury, inotropic support duration, lengths of intensive care unit and hospital stays, and 30-day and one-year mortality. No association was observed between any of the four cardiac biomarkers and the primary outcome. The preoperative levels of Galectin-3 (hazard ratio = 1.2; p < 0.001) and sST2 (hazard ratio = 1.01, p < 0.001) were significantly associated with one-year survival, and their addition to the EuroSCORE II significantly improved the prediction of one-year mortality (p < 0.001). Similarly, Galectin-3 was associated with postoperative acute kidney injury (odds ratio = 1.15, p = 0.001) and improved the prediction of this complication when added to the EuroSCORE II (p = 0.002). CONCLUSIONS: These results suggested that the ability of cardiac biomarkers to predict short-term outcome after cardiac surgery, though of interest, appears limited. Conversely, cardiac biomarkers may have the potential to refine the prediction of long-term outcome. Admittedly, all positive results were obtained on secondary outcomes and must be regarded with caution.

BACKGROUND: This study was conducted to determine the incidence of postoperative conduction disorders and need for pacemaker (PM) implantation after aortic valve replacement (AVR) with the Perceval prosthesis (Livanova, Saluggia, Italy). METHODS: From January 2007 to December 2017, 908 patients underwent AVR with Perceval S in 5 participating centers. Study end points focused on electrocardiographic changes after AVR and the incidence of new PM implantation in 801 patients after exclusion of patients with previous PM (n = 48) or patients undergoing tricuspid (n = 28) and/or atrial fibrillation ablation (n = 31) surgery. Logistic regression analysis was performed to determine risk factors for PM need. RESULTS: Mean age was 79.7 ± 5.2 years, and 476 (59.4%) were women. Median logistic European System for Cardiac Operative Risk Evaluation (2011 revision) score was 4.1% (interquartile range, 2.6%-6.0%). Isolated AVR was performed in 441 patients (55.1%). Associated procedures were coronary artery bypass grafting in 309 (38.6%) and mitral valve surgery in 51 (6.4%). Overall 30-day mortality was 3.9% and was 2.8% for isolated AVR. Electrocardiographic changes included a significant increase of left bundle branch block from 7.4% to 23.7% (P < .001) and development of complete atrioventricular block requiring PM implantation in 9.5%. Multivariable analysis revealed independent of a learning period (odds ratio [OR], 1.91; 95% confidence limits (CL), 1.16-3.13; P = .011), preexisting right-bundle branch block (OR, 2.77; 95% CL, 1.40-5.48; P = .003), intraoperative prosthesis repositioning (OR, 6.70; 95% CL, 1.89-24.40; P = .003), and size extra large (OR, 6.81; 95% CL, 1.55-29.96; P = .011) as significant predictors of PM implantation. CONCLUSIONS: In a challenging elderly population, use of the Perceval S for AVR provides low operative mortality but at the risk of an increased PM implantation rate. Besides preexisting right bundle branch block, the significant effect of size extra large, an increased valve size/body surface area ratio, and need for intraoperative repositioning on PM rate are underscoring the reappraisal of the annular sizing policy.

Ascending aorta mycotic aneurysm is a rare entity. It is a life-threatening condition because of the possibility of aortic dissection, or rupture. Escherichia coli is recognised as an uncommon cause of aortic mycotic aneurysm. An 81-year-old woman with a history of Escherichia coli pyelonephritis 4 months previously, was admitted to our centre for a mycotic aneurysm of the ascending aorta caused by Escherichia coli. She was successfully treated by urgent in situ replacement of the ascending aorta with a cryopreserved homograft, combined with antibiotics. Although infrequent, Escherichia coli mycotic aneurysm should be suspected in older patients with atherosclerosis and who developed septicaemia. Prompt treatment with a combination of appropriate antibiotics and surgery is required.

BACKGROUND: Streptococcus agalactiae (GBS) infective endocarditis (IE) is a rare clinical entity. It is associated with a high mortality rate compared to other streptococci endocarditis. The aim of this study is to define the clinical characteristics, treatment and outcomes of a series of eight non-pregnant adults with GBS IE managed by a combination of antibiotics and surgery at our institution. METHODS: We retrospectively reviewed the medical records of all adult patients with a definite diagnosis of IE by Duke modified criteria and who underwent surgery at our centre between January 2008 and December 2018. RESULTS: A total of 190 patients underwent surgery for IE during the study period. Eight cases of GBS IE were identified, including six males and two females. The mean aged was 54 years (range, 32-68). Seven cases suffered native valve endocarditis and one involved an aortic bioprosthesis. Seven patients had underlying comorbidities. Furthermore, four patients had experienced serious complications. Of these, the most common were heart failure, septic shock, and cerebral emboli. Vegetations tended to be large, very mobile, and pedunculated. Most of the patients were treated with penicillin plus an aminoglycoside. Surgery was emergently performed in one patient and urgently performed in seven patients. In- hospital mortality rate was 37.5%. CONCLUSION: GBS IE is a virulent disease with an aggressive clinical course. It mostly affects patients with debilitating diseases. Early surgery should be considered to prevent the development of serious complications. However, overall mortality rate remains high despite surgical treatment.

Cardiac intimal sarcoma is extremely rare and aggressive primary malignant cardiac tumors. Here, we reported the case of a young man initially operated for a tumor of the left atrium, causing a dynamic obstruction of the mitral valve and (mis-)diagnosed as a myxoma at the histopathological analysis. Patient presented a local recurrence at 3 months and was reoperated. Pathology revealed this time the presence of an intimal sarcoma. Patient received adjuvant chemotherapy. Despite a good local control, the 1-year follow-up positron emission tomography scan revealed the presence of a metastasis in the left adrenal gland that was surgically resected. This article aims to highlight the risk of misdiagnosis in case of cardiac tumors, the hypothetical concept of malignant transformation of a cardiac myxoma, the aggressive course of the extremely rare cardiac intimal sarcoma, and the therapeutic modalities available to treat this pathology.

Aberrant origin of the coronary artery from the opposite sinus of Valsalva is a rare congenital coronary anomaly associated with increased risk of myocardial ischemia and sudden death in young patients. We report a case of resuscitated sudden cardiac death in a patient with an anomalous origin of the right coronary artery, arising from the left sinus of Valsalva and coursing between the ascending aorta and the pulmonary artery. Successfully coronary arterial bypass grafting using the left radial artery was performed. Despite the risk of fatal issue, surgical management of patient with this coronary anomaly still remains controversial.

Bronchogenic cysts arise from an abnormal budding of the ventral diverticulum of the foregut or the tracheobronchial tree during embryogenesis. Pericardial location of these cysts is very rare. We describe a case of a young asymptomatic woman with an intrapericardial cystic mass compressing the right heart. Because of severe adhesions of the mass to the ascending aorta and to the right coronary artery, these structures were injured during surgical resection requiring the replacement of the ascending aorta and a coronary artery by-pass graft. Only the histopathologic findings provided the final diagnosis.

Penetrating injuries of the subclavian artery are associated with a high morbidity and mortality rate. Endovascular treatment with covered stents (stent grafts) has emerged as an effective alternative to surgery, but this new technique is not exempt from complications. We report the case of a male gunshot victim, treated by a covered stent for haemorrhagic shock due to partial subclavian rupture.

The case of a 30-year-old non-Marfan woman who developed a type III acute aortic dissection 5 days after delivery, followed within 16 h by an independent type II dissection, is reported. Preoperative CT scan imaging and TEE suggested metachronous type II and type III dissection. This was confirmed at surgery, where limited dissection of the aortic root without communication with the isthmic area via the aortic arch was evidenced. The patient underwent repair of the aortic root and adjacent ascending aorta and was medically treated for her type III dissection. This is the first report of metachronous acute aortic dissections in puerperium.
