Long-term cardiovascular inflammation and fibrosis in a murine model of vasculitis induced by Lactobacillus casei cell wall extract.

Background: Kawasaki disease (KD), an acute febrile illness and systemic vasculitis, is the leading cause of acquired heart disease in children in industrialized countries. KD leads to the development of coronary artery aneurysms (CAA) in affected children, which may persist for months and even years after the acute phase of the disease. There is an unmet need to characterize the immune and pathological mechanisms of the long-term complications of KD. Methods: We examined cardiovascular complications in the Lactobacillus casei cell wall extract (LCWE) mouse model of KD-like vasculitis over 4 months. The long-term immune, pathological, and functional changes occurring in cardiovascular lesions were characterized by histological examination, flow cytometric analysis, immunofluorescent staining of cardiovascular tissues, and transthoracic echocardiogram. Results: CAA and abdominal aorta dilations were detected up to 16 weeks following LCWE injection and initiation of acute vasculitis. We observed alterations in the composition of circulating immune cell profiles, such as increased monocyte frequencies in the acute phase of the disease and higher counts of neutrophils. We determined a positive correlation between circulating neutrophil and inflammatory monocyte counts and the severity of cardiovascular lesions early after LCWE injection. LCWE-induced KD-like vasculitis was associated with myocarditis and myocardial dysfunction, characterized by diminished ejection fraction and left ventricular remodeling, which worsened over time. We observed extensive fibrosis within the inflamed cardiac tissue early in the disease and myocardial fibrosis in later stages. Conclusion: Our findings indicate that increased circulating neutrophil counts in the acute phase are a reliable predictor of cardiovascular inflammation severity in LCWE-injected mice. Furthermore, long-term cardiac complications stemming from inflammatory cell infiltrations in the aortic root and coronary arteries, myocardial dysfunction, and myocardial fibrosis persist over long periods and are still detected up to 16 weeks after LCWE injection.

The Year in Aortic Surgery: Selected Highlights From 2023.

This article reviews the recent and relevant literature to the field of aortic surgery. Specific areas highlighted include outcomes of Stanford type A dissection, management of acute aortic syndromes, management of aortic aneurysms, and traumatic aortic injury. Although the focus was on articles from 2023, literature from prior years also was included, given that this article is the first of a series. Notably, the pertinent sections from the 2022 American College of Cardiology/American Heart Association Guidelines for the Diagnosis and Management Aortic Disease are discussed.

Double arterial vs. single axillary cannulation in acute type A aortic dissections: a meta-analysis.

Aim: To evaluate the effects of double (axillary and femoral) vs. single (axillary) cannulation on early outcomes of acute type A aortic dissection (ATAAD). Materials & methods: Meta-analysis using PubMed/MEDLINE, Scopus, and Cochrane databases through August 23, 2023. Focused on operative mortality, postoperative stroke, re-exploration for bleeding, spinal cord injury, and renal replacement therapy. Results: Among 5 propensity score-matched studies with 2127 patients, double cannulation showed comparable mortality and higher rates of postoperative stroke (pooled odds ratio: 1.69, 95% confidence interval: 1.19-2.39) and need for renal replacement therapy (pooled odds ratio: 1.35, 95% confidence interval: 1.13-1.60) compared with single cannulation. Conclusion: Double arterial cannulation in ATAAD surgery is associated with increased postoperative stroke and renal replacement therapy than single cannulation.

What is this summary about? We studied the optimal way to maintain blood flow during surgery for acute aortic dissection. We focused on comparing the use of one tube placement site in the axillary artery with two sites, both in the axillary and femoral arteries, in five previous studies.What were the results? Using two sites was associated with a higher risk of stroke and need for dialysis after surgery than using only one site.What do the results mean? Adding a tube in the femoral artery for blood flow may increase the risk of complications. It appears that placing the tube only in the axillary artery may be a safer choice for appropriately selected patients having this surgery.

Predictors of In-Hospital Mortality in Type A Acute Aortic Syndrome: Data From the RENADA-RO Registry.

BACKGROUND: This study aimed to analyse the baseline characteristics of patients admitted with acute type A aortic syndrome (ATAAS) and to identify the potential predictors of in-hospital mortality in surgically managed patients. METHODS: Data regarding demographics, clinical presentation, laboratory work-up, and management of 501 patients with ATAAS enrolled in the National Registry of Aortic Dissections-Romania registry from January 2011 to December 2022 were evaluated. The primary endpoint was in-hospital all-cause mortality. Multivariate logistic regression was conducted to identify independent predictors of mortality in patients with acute Type A aortic dissection (ATAAD) who underwent surgery. RESULTS: The mean age was 60±11 years and 65% were male. Computed tomography was the first-line diagnostic tool (79%), followed by transoesophageal echocardiography (21%). Cardiac surgery was performed in 88% of the patients. The overall mortality in the entire cohort was 37.9%, while surgically managed ATAAD patients had an in-hospital mortality rate of 29%. In multivariate logistic regression, creatinine value (OR 6.76), ST depression on ECG (OR 6.3), preoperative malperfusion (OR 5.77), cardiogenic shock (OR 5.77), abdominal pain (OR 4.27), age ≥70 years (OR 3.76), and syncope (OR 3.43) were independently associated with in-hospital mortality in surgically managed ATAAD patients. CONCLUSIONS: Risk stratification based on the variables collected at admission may help to identify ATAAS patients with high risk of death following cardiac surgery.

METABOLIC SYNDROME-ASSOCIATED MURINE AORTIC WALL STIFFENING IS ASSOCIATED WITH PREMATURE ELASTIC FIBERS AGING.

Type 2 diabetes (T2D) constitutes a major public health problem, and despite prevention efforts, this pandemic disease is 'one of the deadliest diseases in the world. In 2022, 6.7 million T2D patients died prematurely from vascular complications. Indeed, diabetes increases the risk of myocardial infarction or stroke eightfold. The identification of the molecular actors involved in the occurrence of cardiovascular complications and their prevention are therefore major axes. Our hypothesis is that factors brought into play during physiological aging appear prematurely with diabetes progression. Our study focused on the aging of the extracellular matrix (ECM), a major element in the maintenance of vascular homeostasis. We characterized the morphological and functional aspects of aorta, with a focus on the collagen and elastic fibers of diabetic mice aged from 6 months to non-diabetic mice aged 6 months and 20 months. The comparison with the two non-diabetic models (young and old) highlighted an exacerbated activity of proteases, which could explain a disturbance in the collagen accumulation and an excessive degradation of elastic fibers. Moreover, the generation of circulating elastin-derived peptides reflects premature aging of the ECM. These extracellular elements contribute to the appearance of vascular rigidity, often the origin of pathologies such as hypertension and atherosclerosis. In conclusion, we show that diabetic mice aged 6 months present the same characteristics of ECM wear as those observed in mice aged 20 months. This accelerated aortic wall remodeling could then explain the early onset of cardiovascular diseases and, therefore, the premature death of DT2 patients.

Coarctation of the aorta complicated with bilateral iliac artery dissection: A rare case.

The coarctation of the aorta (CoA) combined with heart defects or cerebral artery aneurysms is more prevalent in clinical practice. However, cases of concurrent bilateral iliac artery dissection (IAD) are extremely rare and have not been reported. Here, we described a case with CoA combined with bilateral IAD. The patient, a 62-year-old male, presented with acute intermittent claudication accompanied by pain and aching in both lower limbs after walking. Following a thorough medical history inquiry and examination, the patient was diagnosed with acute bilateral IAD combined with CoA. The patient underwent endovascular treatment. Postoperatively, the aortic diameter recovered, and the bilateral IAD disappeared, yielding satisfactory therapeutic results. Conclusively, endovascular treatment of aortic coarctation combined with IAD is an effective therapeutic approach, enhancing patient survival and improving their quality of life.

The impact of onset-to-cut time in surgery for stable acute type a aortic dissection-a single-center retrospective cohort study.

OBJECTIVES: The study aim is to investigate the impact of onset-to-cut time on mortality in patients undergoing surgery for stable acute type A aortic dissection. METHODS: Patients who underwent surgery for acute type A aortic dissection between 01/2006 and 12/2021 and available onset-to-cut times were included. Patients with unstable aortic dissection (preoperative shock, intubation, resuscitation, coma, pericardial tamponade and local/systemic malperfusion syndromes) were excluded. After descriptive analysis, a multivariable binary logistic regression for thirty-day mortality was performed. A receiver operating characteristic curve for onset-to-cut time and thirty-day mortality was calculated. Restricted cubic splines were designed to investigate the association between onset-to-cut time and survival. RESULTS: The final cohort consisted of 362 patients. The median onset-to-cut time was 543 (376-1155) min. Thirty-day mortality was 9%. Only previous myocardial infarction (p = 0.018) and prolonged cardiopulmonary bypass time (p < 0.001) were identified as independent risk factors for thirty-day mortality. The corresponding area under the receiver operating characteristic curve showed a value of 0.49. Restricted cubic splines did not indicate an association between onset-to-cut time and survival (p = 0.316). CONCLUSIONS: Onset-to-cut time in the setting of stable acute type A aortic dissection does not seem to be a valid predictor of thirty-day mortality in patients undergoing surgery and stayed stable during the preoperative course.

Review of speckle tracking analysis to measure the size, shape, and contractility of the fetal heart in fetuses with congenital heart defects.

Evaluation of the fetal heart involves two approaches. The first describes a screening protocol in which the heart is imaged in transverse planes that includes the four-chamber view (4CV), left and right outflow tracts, and the 3-vessel-tracheal view. The second approach is a fetal echocardiogram that requires additional cardiac images as well as evaluating ventricular function using diagnostic tools such as M-mode and pulsed Doppler ultrasound. Speckle tracking analysis of the ventricular and atrial endocardium of the fetal heart has focused primarily on computing longitudinal global strain. However, the technology enabling this measurement to occur has recently been adapted to enable the clinician to obtain numerous additional measurements of the size, shape, and contractility of the ventricles and atrial chambers. By using the increased number of measurements derived from speckle tracking analysis, we have reported the ability to screen for tetralogy of Fallot, D-transposition of the great arteries (D-TGA), and coarctation of the aorta by only imaging the 4CV. In addition, we have found that measurements derived from speckle tracking analysis of the ventricular and atrial chambers can be used to compute the risk for emergent neonatal balloon atrial septostomy in fetuses with D-TGA. The purpose of this review is to consolidate our experience in one source to provide perspective on the benefits of speckle tracking analysis to measure the size, shape, and contractility of the ventricles and atria imaged in the 4CV in fetuses with congenital heart defects.

Successful open surgical treatment for persistent type II endoleak following thoracic endovascular aortic repair: a case report.

BACKGROUND: The occurrence of type II endoleaks after endovascular repair of aortic aneurysm has gradually gained increasing attention. We present a case of a patient with an expanding aneurysm after thoracic endovascular aortic repair (TEVAR) for a type II endoleak, in which successful direct ligations of the intercostal artery were performed using a sac incision without cardiopulmonary bypass (CPB) or graft replacement. CASE PRESENTATION: A 62-year-old male patient, previously treated with TEVAR for a descending thoracic aortic aneurysm, presented with ongoing chest discomfort. Based on the diagnosis of a growing aneurysm and type II endoleak, the patient was prepared for CPB and aortic cross-clamping, as a precautions against the possibility of a type I endoleak. A longitudinal opening of the thoracic aortic aneurysm sac was performed following left thoracotomy. Visual confirmation identified the T5 level intercostal artery as the source of the endoleak, and after confirming the absence of a type I endoleak, multiple ligations were applied to the intercostal artery. Follow-up computed tomography confirmed the absence of endoleaks or sac growth. CONCLUSION: In a case involving TEVAR for a thoracic aortic aneurysm, open suture ligations were used to treat type II endoleaks without having to resort to CPB, resulting in successful outcomes.

Lead Acetate-Injected Mice is an Animal Model for Extrapolation of Calcifying Response to Humans Due to Low Involvement of Bone Resorption.

Vascular calcification affects the prognosis of patients with renal failure. Bisphosphonates are regarded as candidate anti-calcifying drugs because of their inhibitory effects on both calcium-phosphate aggregation and bone resorption. However, calcification in well-known rodent models is dependent upon bone resorption accompanied by excessive bone turnover, making it difficult to estimate accurately the anti-calcifying potential of drugs. Therefore, models with low bone resorption are required to extrapolate anti-calcifying effects to humans. Three bisphosphonates (etidronate, alendronate, and FYB-931) were characterised for their inhibitory effects on bone resorption in vivo and calcium-phosphate aggregation estimated by calciprotein particle formation in vitro. Then, their effects were examined using two models inducing ectopic calcification: the site where lead acetate was subcutaneously injected into mice and the transplanted, aorta obtained from a donor rat. The inhibitory effects of bisphosphonates on bone resorption and calcium-phosphate aggregation were alendronate > FYB-931 > etidronate and FYB-931 > alendronate = etidronate, respectively. In the lead acetate-induced model, calcification was most potently suppressed by FYB-931, followed by alendronate and etidronate. In the aorta-transplanted model, only FYB-931 suppressed calcification at a high dose. In both the models, no correlation was observed between calcification and bone resorption marker, tartrate-resistant acid phosphatase (TRACP). Results from the lead acetate-induced model showed that inhibitory potency against calcium-phosphate aggregation contributed to calcification inhibition. The two calcification models, especially the lead acetate-induced model, may be ideal for the extrapolation of calcifying response to humans because of calcium-phosphate aggregation rather than bone resorption as its mechanism.

A Cardiologist's Clinical Dilemma: An Incidental Finding of a Potentially High-Risk Anomalous Right Coronary Artery Origin.

Coronary artery anomalies may place patients at risk for various adverse events. We present a case of a 62-year-old male with a two-year history of intermittent chest pain. A computed tomography coronary angiogram revealed a rare finding of an anomalous right coronary artery (ARCA) originating from the left ascending aorta, with high-risk features. This case highlights the complexities in diagnosing and managing ARCA, underscoring the importance of individualized care and careful consideration of invasive intervention risks versus potential benefits.

A secondary abdominal aorta-duodenal fistula accompanied with acquired Immune Deficiency Syndrome presented with recurrent sepsis: a case report.

BACKGROUND: Abdominal aorta-duodenal fistulas are rare abnormal communications between the abdominal aorta and duodenum. Secondary abdominal aorta-duodenal fistulas often result from endovascular surgery for aneurysms and can present as severe late complications. CASE PRESENTATION: A 50-year-old male patient underwent endovascular reconstruction for an infrarenal abdominal aortic pseudoaneurysm. Prior to the operation, he was diagnosed with Acquired Immune Deficiency Syndrome and Syphilis. Two years later, he was readmitted with lower extremity pain and fever. Blood cultures grew Enterococcus faecium, Salmonella, and Streptococcus anginosus. Sepsis was successfully treated with comprehensive anti-infective therapy. He was readmitted 6 months later, with blood cultures growing Enterococcus faecium and Escherichia coli. Although computed tomography did not show contrast agent leakage, we suspected an abdominal aorta-duodenal fistula. Esophagogastroduodenoscopy confirmed this suspicion. The patient underwent in situ abdominal aortic repair and received long-term antibiotic therapy. He remained symptom-free during a year and a half of follow-up. CONCLUSIONS: This case suggests that recurrent infections with non-typhoidal Salmonella and gut bacteria may be an initial clue to secondary abdominal aorta-duodenal fistula.

Right coronary sinus aneurysm repair.

In this case report, we describe the surgical treatment of a right coronary sinus aneurysm. A 69-year-old male patient was screened because of palpitations. He was finally diagnosed with an aneurysm of the sinus of Valsalva of the right coronary cusp. According to current aortic guidelines, surgical reconstruction was proposed. The patient underwent a cardiac operation through a median sternotomy under routine cardiopulmonary bypass. After aortic cross-clamping, the aorta was opened and the connection between the aorta and the aneurysm was clearly visualized, underneath the ostium of the right coronary artery. After excision of the right coronary button and the remaining right coronary sinus wall, this sinus was reconstructed with a Dacron graft, with subsequent coronary reimplantation. The postoperative course was uneventful. The patient was discharged on postoperative day 7. A complete sinus reconstruction was preferred over local patching of the defect because of the proximity of the aneurysm sac to the right coronary artery and the fragile, thin aortic tissue just underneath the coronary ostium.

Losing, regaining, and continuing to build self-confidence - a qualitative, phenomenological study of being physically active with a type B aortic dissection.

PURPOSE: To gain a comprehensive understanding of experiences related to being physically active in participants with an uncomplicated type B aortic dissection. MATERIALS AND METHODS: We performed a qualitative, phenomenological study. First-person accounts of adults, who at least one year ago had an uncomplicated type B aortic dissection, were collected using semi-structured interviews. The audio recordings of the interviews were transcribed verbatim and analyzed with interpretative phenomenological analysis. RESULTS: We collected, in total, 644 min interview data from 14 participants. Three patterns were interpreted: losing self-confidence, regaining self-confidence, and continuing to build self-confidence. Experiencing symptoms when pushing limits, challenges with energy management, and side effects of medication caused loss of self-confidence. Changes in identity, reaching milestones that reflect improvement, and support from others and tools helped participants regain self-confidence. To continuing to build self-confidence, participants indicated they needed success experiences and activities make life worth living. CONCLUSIONS: Self-confidence in adults with an uncomplicated type B aortic dissection changes immediately after the diagnosis of the aortic dissection. Rehabilitation professionals can support adults regaining and continuing to build self-confidence, aiming for the perfect balance between blood pressure regulation, quality of life, and being physically active.Implications for rehabilitationRehabilitation professionals should support regaining and continuing to build self-confidence related to being physically active in adults with type B aortic dissection in the early stages of recovery and beyond.Adults with an uncomplicated type B aortic dissection want rehabilitation professionals to tell them primarily what is possible (recommendations) rather than what is not allowed (rules).Rehabilitation professionals should help adults with an uncomplicated type B aortic dissection to explore, push and, ultimately, accept limits related to exercise tolerance.

A complicated case of primary aortojejunal fistula: A case report.

BACKGROUND: Aortoenteric fistulas are rare and life-threatening pathology characterized by an abnormal connection between the aorta and the gastrointestinal tract. CASE PRESENTATION: The patient is a 61-year-old male who initially presented with hypogastric pain, hematemesis, and melena. Computed tomography angiography (CTA) revealed an abdominal aorta aneurysm but not a fistula. Imaging modalities were inconclusive in the diagnosis. The patient became unstable hemodynamically and was transferred to the operation room. The definitive diagnosis of aortoenteric fistula was confirmed during surgical exploration. Urgent surgery was performed; however, the patient experienced a cascade of complications, including rebleeding, intestinal leakage, and hemodynamic instability due to aortic bleeding. Despite rigorous interventions, the patient expired due to multiple organ failure 53 days after the first repair surgery. CLINICAL DISCUSSION: There is no definite imaging method due to the lack of guidelines, and the absence of exact findings has led to intraoperative diagnosis in up to 50 % of cases. This is one of the modalities of choice to examine suspected aortoenteric fistulas. Many authors prefer Computed tomography (CT) with intravenous contrast for suspected AEF despite its limitations in clarity. Others recommend CT angiography as the preferred modality. It is worth noting that, as reported in a comprehensive retrospective review, the mortality rate is approximately 46 % within 60 days after AEF repair surgery. CONCLUSION: This report adds to the limited data about primary aortojejunal fistulas, an extremely rare type of aortoenteric fistulas which has been reported in only a few cases. Understanding the importance of promptly suspecting, diagnosing, and intervening is crucial, emphasizing the importance of sharing such cases for medical guidance and better patient outcomes.

Generalized Arterial Calcification of Infancy Mimicking Coarctation of Aorta in a Neonate.

Generalized arterial calcification of infancy (GACI) is a rare genetic condition with varied clinical presentation. Consequently, diagnosis is frequently delayed or missed. GACI has a poor prognosis, with more than half of patients dying before the age of 6 months. Early diagnosis and treatment with bisphosphonates have been shown to improve survival in these patients. This is a case report of a newborn with respiratory distress who was initially diagnosed with coarctation of the aorta at echocardiography. Further imaging with CT revealed the aortic narrowing to be associated with GACI.

Influence of Aortic Arch Morphology on Renal Perfusion in Patients with Coarctation of the Aorta: An Exploratory Study.

Objectives: The configuration of the aortic arch, particularly a Gothic arch shape, in individuals with corrected coarctation of the aorta (CoA) has been associated with a decreased systolic wave amplitude across the arch, which could potentially impair renal perfusion and elevate the risk of arterial hypertension. This study aims to explore the relationship between the morphological characteristics of the aortic arch and their impact on renal perfusion in patients with CoA. Methods: Seventy-one subjects with corrected CoA underwent continuous 24 h ambulatory blood pressure monitoring, computed tomography to assess the aortic arch, and renal perfusion scanning. Subjects were stratified into three groups based on the height-to-width (H/W) ratio of their aortic arch: Group 1 with a H/W ratio of <0.65, Group 2 with a H/W ratio between 0.65 and 0.85, and Group 3 with a H/W ratio of >0.85. Results: Groups 1 and 2 (53,78% and 62.63%) presented with a higher hypertension prevalence of elevated blood pressure than Group 3 (38.89%). Notable variations were observed among the subjects in the time to peak perfusion (Tmax) in the left kidney across the groups. Group 1 showed a median Tmax at 0.27, Group 2 at 0.13, and Group 3 at -0.38 (p-value = 0.079). The differences in Tmax for the right kidney followed a similar trend but were not statistically significant (Group 1 at 0.61, Group 2 at 0.22, and Group 3 at 0.11; p-value = 0.229). Conclusions: This study suggests that variations in the aortic arch morphology might not significantly influence renal perfusion in CoA patients. This indicates the potential adaptability of the renal blood flow, which appears to compensate for reduced perfusion, thus minimizing adverse effects on the kidney function. This adaptability suggests an inherent physiological resilience, emphasizing the need for further targeted research to understand the specific interactions and impacts on treatment strategies for CoA.

Less invasive replacement of aortic root, ascending aorta and hemiarch via partial upper sternotomy: a propensity-score matched comparison with full sternotomy.

OBJECTIVES: Less invasive surgery has emerged as an option for aortic pathologies. The current study compared our experience on early postoperative results of patients with aortic surgery between partial upper sternotomy (PUS) and full sternotomy (FS). METHODS: We performed a retrospective analysis of the data of patients undergoing aortic root surgery with concomitant ascending aorta and hemiarch replacement. Exclusion criteria were type A aortic dissection and other concomitant major cardiac surgery. After propensity-score matching, we compared the perioperative outcomes of patients undergoing surgery with PUS vs FS. RESULTS: 161 patients operated on between January 2013 and September 2022 met the inclusion criteria (PUS: n = 22, FS: n = 139). Propensity score matching yielded 22 pairs with a balanced distribution of propensity scores and covariates between the compared groups. There was no evidence that PUS affects cardiopulmonary bypass [108(67-119) vs 113(87-148) min, p = 0.154; PUS vs FS] and circulatory arrest duration [9(7-10) vs 9(8-13) min, p = 0.264; PUS vs FS]. There was a reduced cross-clamp duration in the PUS group [88(58-96) vs 92(71-122) min, p = 0.032]. Cumulative sum charts (CUSUM) have shown consistently low cross-clamp and circulatory arrest duration for two experienced surgeons who performed 20 of the procedures in the PUS group (10 each). Perioperative mortality and morbidity were low, with no in-hospital mortality in the PUS group [0 vs 1(4.5%), p > 0.999] and absence of strokes in both groups. CONCLUSIONS: In summary, our initial experience suggests that less invasive aortic root, ascending aorta, and hemiarch replacement via partial upper sternotomy could be performed in our patient cohort as safely as via full sternotomy. Advantages for the patient are reduced surgical trauma, improved cosmetic results, and-presumably-less pain.

A rare case of a simultaneous post-dissection saccular aneurysm of the ascending aorta and large pulmonary artery aneurysm with secondary embolism: a case report.

BACKGROUND: Aneurysms of the pulmonary arteries and the ascending aorta are rare, and both bear a high mortality risk if left untreated. In general, these entities are primarily caused by etiologies such as hypertension, pulmonary arterial hypertension, infection or congenital disorders. Treatment requires a rapid diagnostic work-up or even immediate surgical intervention in acute cases. Nevertheless, surgery entails serious perioperative risks, in particular in patients with multiple comorbidities. CASE PRESENTATION: We discuss a 70-year-old woman presented with decompensated heart failure based on severe pulmonary artery hypertension, coincided by a massive pulmonary artery aneurysm with secondary embolism. Additional diagnostic imaging also showed a chronic post-dissection, saccular aneurysm of the ascending aorta. To our knowledge, this simultaneous diagnosis of a saccular aneurysm of the ascending aorta and a large aneurysm of the pulmonary artery with secondary embolism has not yet been described. Nonetheless, conservative treatment was chosen due to extensive pulmonal and cardiovascular comorbidities and the high-risk profile of surgery. CONCLUSIONS: Extensive aneurysmatic disease of the pulmonary arteries and ascending aorta come with a serious burden of disease, especially if coincided by severe pulmonal and cardiovascular comorbidities. Both conditions can be curatively treated by surgical intervention. However, in every case the risk of surgery and the patient's vitality, comorbidities and wishes should be taken into account to formulate an adequate treatment plan. Therefore, shared decision making is of utter importance.
