The CatLet score and outcome prediction in acute myocardial infarction for patients undergoing primary percutaneous intervention: A proof-of-concept study.

BACKGROUND: The Coronary Artery Tree description and Lesion EvaluaTion (CatLet) score accommodating the variability in coronary anatomy is a recently developed and comprehensive angiographic scoring system aimed at assisting in risk-stratification of patients with coronary artery disease. However, a validation of this angiographic scoring system is lacking. METHODS: The CatLet score was calculated retrospectively in 308 consecutively enrolled patients with acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention. The primary endpoint, major adverse cardiac or cerebrovascular events (MACCEs), was stratified according to CatLet tertiles: CatLetlow ≤14 (n = 124), CatLetmid 15-21 (n = 82) and CatLettop ≥22 (n = 102). RESULTS: The CatLet score alone or after adjusting for a broad spectrum of risk factors, significantly predicted clinical outcomes at a median 4.3-year follow-up. Multivariable-adjusted hazard ratios (95%CI)/unit higher score were 1.05 (1.04-1.07) for MACCE, 1.06 (1.04-1.07) for cardiac death, and 1.05 (1.04-1.07) for all-cause death. When compared to the SYNTAX score, improved discrimination and better calibration of this CatLet score resulted in a significantly refined risk stratification. The overall category-free net reclassification improvement afforded by this CatLet score was as follows: 37.2% (p = .008) for MACCEs, 35.5% (p = .0249) for cardiac death, and 31.8% (p = .0316) for all-cause death. CONCLUSIONS: The ability to integrate the variability in coronary anatomy into angiographic scoring makes the CatLet score a more specific tool for outcome predictions in AMI.

Long-term Follow up of Patients with Acute Aortic Syndromes: Relevance of both Aortic and Non-aortic Events.

BACKGROUND: The aim was to assess the long-term outcome of patients diagnosed with type A and type B acute aortic syndromes (AAS) and the mortality risk predictors. METHODS: A single centre retrospective observational study was performed on consecutive patients diagnosed with AAS and discharged between 2000 and 2016: 242 surgically treated type A, 87 uncomplicated, medically treated type B, and 80 complicated type B who received endovascular/surgical/hybrid treatment. Follow up of discharged patients (5 ± 3.9 years) was almost complete by the end of the study (December 2017). RESULTS: The mean age was 65.3 ± 12.5 years, and 70.2% were men. Long-term all cause mortality was 5.4 per 100 patients per year in surgically treated type A AAS patients and 6.7 per 100 patients per year in type B AAS patients (p = .236). The rates of major aorta related events were 6.1 per 100 patients per year and 13.4 per 100 patients per year, respectively (p < .001). Non-aorta related events during long-term follow up occurred in 18.2 per 100 patients per year in type A and 13.8 per 100 patients per year in type B (p = .055). At the end of follow up 279/409 (68.2%) patients (165/242 type A and 114/167 type B) experienced at least one event. CONCLUSIONS: Among patients with either type A or type B AAS surviving the acute phase, the risk of adverse aorta and non-aorta related events, including death, persists during follow up, so that eventually two thirds of patients will experience at least one event. Notably, all cause mortality after type B AAS exceeds that of type A AAS after three years.

Consensus Document of the Italian Association of Hospital Cardiologists (ANMCO), Italian Society of Cardiology (SIC), Italian Association of Interventional Cardiology (SICI-GISE) and Italian Society of Cardiac Surgery (SICCH): clinical approach to pharmacologic pre-treatment for patients undergoing myocardial revascularization procedures.

The wide availability of effective drugs in reducing cardiovascular events together with the use of myocardial revascularization has greatly improved the prognosis of patients with coronary artery disease. The combination of antithrombotic drugs to be administered before the knowledge of the coronary anatomy and before the consequent therapeutic strategies, can allow to anticipate optimal treatment, but can also expose the patients at risk of bleeding that, especially in acute coronary syndromes, can significantly weigh on their prognosis, even more than the expected theoretical benefit. In non ST-elevation acute coronary syndromes patients in particular, we propose a 'selective pre-treatment' with P2Y12 inhibitors, based on the ischaemic risk, on the bleeding risk and on the time scheduled for the execution of coronary angiography. Much of the problems concerning this issue would be resolved by an early access to coronary angiography, particularly for patients at higher ischaemic and bleeding risk.

ANMCO/SIC/SICI-GISE/SICCH Executive Summary of Consensus Document on Risk Stratification in elderly patients with aortic stenosis before surgery or transcatheter aortic valve replacement.

Aortic stenosis is one of the most frequent valvular diseases in developed countries, and its impact on public health resources and assistance is increasing. A substantial proportion of elderly people with severe aortic stenosis is not eligible to surgery because of the advanced age, frailty, and multiple co-morbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy. However, a significant percentage of patients die or show no improvement in quality of life (QOL) in the follow-up. In the decision-making process, it is important to determine: (i) whether and how much frailty of the patient influences the risk of procedures; (ii) how the QOL and the individual patient's survival are influenced by aortic valve disease or from other associated conditions; and (iii) whether a geriatric specialist intervention to evaluate and correct frailty or other diseases with their potential or already manifest disabilities can improve the outcome of surgery or TAVI. Consequently, in addition to risk stratification with conventional tools, a number of factors including multi-morbidity, disability, frailty, and cognitive function should be considered, in order to assess the expected benefit of both surgery and TAVI. The pre-operative optimization through a multidisciplinary approach with a Heart Team can counteract the multiple damage (cardiac, neurological, muscular, respiratory, and kidney) that can potentially aggravate the reduced physiological reserves characteristic of frailty. The systematic application in clinical practice of multidimensional assessment instruments of frailty and cognitive function in the screening and the adoption of specific care pathways should facilitate this task.

ANMCO/AIAC/SICI-GISE/SIC/SICCH Consensus Document: percutaneous occlusion of the left atrial appendage in non-valvular atrial fibrillation patients: indications, patient selection, staff skills, organisation, and training.

Atrial fibrillation (AF) is the most common arrhythmia and its prevalence is increasing due to the progressive aging of the population. About 20% of strokes are attributable to AF and AF patients are at five-fold increased risk of stroke. The mainstay of treatment of AF is the prevention of thromboembolic complications with oral anticoagulation therapy. Drug treatment for many years has been based on the use of vitamin K antagonists, but recently newer and safer molecules have been introduced (dabigatran etexilate, rivaroxaban, apixaban, and edoxaban). Despite these advances, many patients still do not receive adequate anticoagulation therapy because of contraindications (relative and absolute) to this treatment. Over the last decade, percutaneous closure of left atrial appendage, main site of thrombus formation during AF, proved effective in reducing thromboembolic complications, thus offering a valid medical treatment especially in patients at increased bleeding risk. The aim of this consensus document is to review the main aspects of left atrial appendage occlusion (selection and multidisciplinary assessment of patients, currently available methods and devices, requirements for centres and operators, associated therapies and follow-up modalities) having as a ground the significant evolution of techniques and the available relevant clinical data.

Extracorporeal membrane oxygenation support in refractory cardiogenic shock: treatment strategies and analysis of risk factors.

Two centrifugal pumps, the RotaFlow (Maquet, Jostra Medizintechnik AG, Hirrlingen, Germany) and Levitronix CentriMag (Levitronix LCC, Waltham, MA, USA), used in central or peripheral veno-arterial extracorporeal membrane oxygenation (ECMO) support systems have been investigated, in terms of double-center experience, as treatment for patients with refractory cardiogenic shock (CS). Between January 2006 and December 2012, 228 consecutive adult patients were supported on RotaFlow (n=213) or CentriMag (n=15) ECMO, at our institutions (155 men; age 58.3±10.5 years, range: 19-84 years). Indications for support were: failure to wean from cardiopulmonary bypass in the setting of postcardiotomy (n=118) and primary donor graft failure (n=37); postacute myocardial infarction CS (n=27); acute myocarditis (n=6); and CS on chronic heart failure (n=40). A peripheral ECMO setting was established in 126 (55.2%) patients while it was established centrally in 102 (44.7%). Overall mean support time was 10.9±9.7 days (range: 1-43 days). Eighty-four (36.8%) patients died on ECMO. Overall success rate, in terms of survival on ECMO (n=144), weaning from mechanical support (n=107; 46.9%), bridge to mid-long-term ventricular assist device (n=6; 2.6%), and bridge to heart transplantation (n=31; 13.5%), was 63.1%. One hundred twenty-two (53.5%) patients were successfully discharged. Stepwise logistic regression identified blood lactate level and MB isoenzyme of creatine kinase (CK-MB) relative index at 72 h after ECMO initiation, and number of packed red blood cells (PRBCs) transfused on ECMO as significant predictors of mortality on ECMO (P=0.010, odds ratio [OR]=2.94; 95% confidence interval [CI]=1.10-3.14; P=0.010, OR=2.82, 95% CI=1.014-3.721; and P=0.011, OR=2.69; 95% CI=1.06-4.16, respectively). Central ECMO population had significantly higher rate of continuous veno-venous hemofiltration need and bleeding requiring surgery events compared with the peripheral ECMO setting population. No significant differences were seen by comparing the RotaFlow and CentriMag populations in terms of device performance. At follow-up, persistent heart failure with left ventricle ejection fraction (LVEF)≤40% was a risk factor after hospital discharge. Patients with a poor hemodynamic status may benefit from rapid central or peripheral insertion of ECMO. The blood lactate level, CK-MB relative index, and PRBCs transfused should be strictly monitored during ECMO support. In addition, early ventricular assist device placement or urgent listing for heart transplant should be considered in patients with persistent impaired LVEF after ECMO.

Single-stage frozen elephant trunk reconstruction in complex disease of the aortic arch with aberrant right subclavian artery.

Aberrant right subclavian artery (ARSA) is the most common anomaly of the aortic arch. We describe two cases of patients affected by complex lesions of the aortic arch with the ARSA, both treated with the frozen elephant trunk technique and reconstruction of the ARSA.

Use of mechanical circulatory support devices in end-stage heart failure patients.

BACKGROUND: Mechanical circulatory support (MCS) is the standard therapy for the management of acute or chronic end-stage heart failure. We report on our two-center experience with MCS therapy. METHODS: Between January 2000 and December 2012, 116 adult patients (mean age 56.8 ± 9.9 years, range: 31 to 76 years) were primarily supported on temporary or long-term ventricular assist devices (VADs) or total artificial hearts (TAHs) at our institutions. Temporary extracorporeal radial VAD support was established in 50 patients (43.1%) (Group A) whereas 66 (56.8%) patients received long-term paracorporeal and intracorporeal VAD or TAH (Group B). LVAD support was established in 63 patients (54.3%), with BVAD/TAH support in 29 (25%). A temporary CentriMag was the only device adopted as an isolated RVAD support, being placed in 24 patients (20.6%). RESULTS: In Group A, the overall mean support time was 10.2 ± 6.6 days (range: 3 to 43 days) and the overall success rate was 55.1% (27 patients). The mean LVAD support time was 357 ± 352.3 days (range: 1 to 902 days) in Group B and 98 ± 82.6 days (range: 8 to 832 days) in BVAD/TAH patients, with success rates of 72.5% (37 patients) and 46.6% (seven patients), respectively. The heart transplantation (Htx) rate for both groups combined was 25.8% (n = 30). The overall one- and five-year survival rates after Htx were 73.3% and 60%, respectively. CONCLUSIONS: When a decision to treat with VAD or TAH is made early, either modality can be used as an alternative to Htx, affording comparable early to mid-term outcomes.

Does EuroSCORE II perform better than its original versions? A multicentre validation study.

AIMS: The European system for cardiac operation risk evaluation (EuroSCORE) is widely used for predicting in-hospital mortality after cardiac surgery. A new score (EuroSCORE II) has been recently developed to update the previously released versions. This study was undertaken to validate EuroSCORE II, to compare its performance with the original EuroSCOREs and to evaluate the effects of the removal of those factors that were included in the score even if they were statistically non-significant. METHODS AND RESULTS: Data on 12,325 consecutive patients who underwent major cardiac surgery in a 6-year period were retrieved from three prospective institutional databases. Discriminatory power was assessed using the c-index and comparison among the scores' performances was performed with Delong, bootstrap, and Venkatraman methods. Calibration was evaluated with calibration curves and associated statistics. The in-hospital mortality rate was 2.2%. The discriminatory power was high and similar in all algorithms (area under the curve 0.82, 95% CI: 0.79-0.84 for additive EuroSCORE; 0.82, 95% CI: 0.79-0.84 for logistic EuroSCORE; 0.82, 95% CI: 0.80-0.85 for EuroSCORE II). The EuroSCORE II had a fair calibration till 30%-predicted values and over-predicted beyond. The removal of non-significant factors from EuroSCORE II did not affect performance, being both the calibration and discrimination comparable. CONCLUSION: This validation study demonstrated that EuroSCORE II is a good predictor of perioperative mortality. It showed an optimal calibration until 30%-predicted mortality. Nonetheless, it does not seem to significantly improve the performance of older versions in the higher tertiles of risk. Moreover, it could be simplified, as the removal from the algorithm of non-significant factors does not alter its performance.

Thoracic aortic aneurysm in infancy in aneurysms-osteoarthritis syndrome due to a novel SMAD3 mutation: further delineation of the phenotype.

Recently, mutations in the SMAD3 gene were found to cause a new autosomal dominant aneurysm condition similar to Loeys-Dietz syndrome (LDS), mostly with osteoarthritis, called aneurysms-osteoarthritis syndrome (AOS). Our 3-year-old propositus underwent correction of an inguinal hernia at 3 months and substitution of the ascending aorta for pathologic dilation at 12 months of age. Family history reveals aortic dilation in his mother at 30 years, death due to aortic dissection of an 18-year-old maternal aunt, surgical replacement of the ascending aorta because of aneurysm in a maternal uncle at 19 years, postpartum death of the maternal grandmother at 24 years and surgical intervention because of thoracic aortic aneurysm in a brother of the propositus' grandmother at 54 years. The affected individuals present with several other signs of connective tissue disease, but the two adult patients evaluated revealed no radiologic evidence of osteoarthritis. Molecular testing of the TGFBR1 and TGFBR2 genes, involved in LDS, resulted negative, but analysis of SMAD3 disclosed the novel heterozygous loss-of-function mutation c.1170_1179del (p.Ser391AlafsX7) in exon 9 in all affected family members, confirming the diagnosis of AOS. SMAD3 mutations should be considered in patients of all ages with LDS-like phenotypes and negative TGFBR1/2 molecular tests, especially in the presence of aortic root or ascending aortic aneurysms, even though signs of early onset osteoarthritis are absent.

Frozen elephant trunk in acute aortic dissection: a literature review.

Background: Acute aortic dissection is a life-threatening condition that requires urgent surgical treatment. The frozen elephant trunk (FET) technique, including the Thoraflex hybrid prosthesis, has emerged as an effective strategy for treating complex aortic pathologies. With the widespread application of the FET technique, it continues to evolve, aiming to simplify procedures and reduce complications. These advancements provide improved outcomes and help save lives in patients with acute aortic dissection. Methods: For this review, PubMed databases were utilized from inception to March 2023. A descriptive approach was employed to identify and present the evidence regarding the application of the FET technique in acute settings and its clinical implications on the postoperative course. Results: In the reviewed studies, FET was a commonly used treatment approach for acute type A aortic dissection. A comprehensive analysis of 12 studies, comprising over 4056 FET procedures, revealed varying rates of early mortality (up to 21.1%), perioperative stroke (ranging from 2.7 to 18.0%), and spinal cord ischemia (ranging from 0 to 8.2%). During the follow-up period, which ranged from 6 to 108 months, the mortality rate was reported to be as high as 38%. Conclusions: The surgical management of acute aortic dissection remains challenging, but FET has shown promising results. Experienced teams have achieved acceptable in-hospital mortality and stroke rates, along with a lower risk of spinal cord injury compared to conventional repair. Furthermore, the FET technique has demonstrated positive alterations in the structure of the distal aorta, potentially improving long-term survival and reducing the necessity for future procedures.

Development of aortic arch surgery in Bologna and reflections on current strategy of cerebral protection.

Complications after open arch repair much decreased over time thanks to better methods of organ and cerebral protection. The crossroads was the introduction of antegrade cerebral perfusion as a method of cerebral protection. Other intraoperative techniques also contributed to facilitate arch reconstruction, such as performing circulatory arrest at higher core temperature, using hybrid grafts or endografts, and monitoring cerebral functions during the procedure. As part of this exciting process, we go back in Bologna in the early 1970s to relive some of these fundamental steps on aortic arch surgery. Today a large number of issues on cerebral protection remain for which we have incomplete responses. Probably, a super specialized approach and endovascular techniques will continue to improve the quality of care of patients with different arch pathologies.

BioGlue® is not associated with polypropylene suture breakage after aortic surgery.

Objective: We have encountered broken or damaged polypropylene sutures (Prolene®) at the anastomotic sites during aortic reoperations. Because a surgical sealant, bovine serum albumin-glutaraldehyde (BioGlue®), was used in previous aortic surgery in some of these cases, we undertook this in vitro study to evaluate whether the use of BioGlue® was associated with breakage of polypropylene sutures at the aortic anastomosis. Materials and methods: The broken polypropylene sutures, anastomotic sites and aortic tissue at the location of suture breakage were visually inspected and evaluated intraoperatively. Six human cadaveric aortic samples were incised circumferentially and anastomosed proximally to a valved conduit with running 4-0 polypropylene sutures (Prolene®). In the test group (n = 3), BioGlue® was applied directly to the Prolene® sutures at the anastomotic sites, while in the control group (n = 3) the anastomoses were not sealed with any surgical adhesive. The six samples were immersed in Dulbecco's phosphate buffered saline solution and mounted on a M-6 Six Position Heart Valve Durability Testing System and tested up to 120 million cycles for a 2-year period. During and upon completion of the testing, the integrity of Prolene® sutures, the anastomosis and aortic tissues was regularly assessed by visual inspection. Results: Intraoperative findings included a stretched and thin aortic wall (some with thrombus), a small cleft between the aortic tissue and the Dacron vascular graft. An excessive amount of BioGlue® was often found around the anastomosis, with cracking material, but no signs of mechanical damage were observed in these cases. Upon visual inspection during and after in vitro testing, there was no apparent damage to the polypropylene sutures on the interior or exterior of the aortic anastomoses in any of the samples. No difference was observed in the physical integrity of the polypropylene sutures at anastomotic lines, the anastomoses and aortic tissues between the test and control samples. Conclusions: The results of this study suggest that the use of BioGlue® was not associated with breakage of the polypropylene sutures at the anastomotic sites after aortic dissection repair.

Sutureless versus transcatheter aortic valves in elderly patients with aortic stenosis at intermediate risk: A multi-institutional study.

OBJECTIVE: This multi-institutional study compares the long-term outcome of elderly patients with severe aortic stenosis and an intermediate risk profile undergoing sutureless versus transcatheter aortic valve implantation. METHODS: From 2008 to 2015, 967 elderly patients (>75 years) with intermediate risk (Society of Thoracic Surgeons score 4%-8%) and isolated aortic stenosis were included in the study (sutureless valve = 481; transcatheter aortic valve implantation = 486). After propensity score matching, 2 matched groups of 291 patients were obtained. Transcatheter valves implanted in patients were the CoreValve (Medtronic, Minneapolis, Minn), Edwards SAPIEN-XT (Edwards Lifesciences, Irvine, Calif), and Acurate-TA (Symetis, Lausanne, Switzerland). Primary end points included all-cause death at 30 days and 5 years. Secondary end points included early and 5-year incidence of composite adverse events (major adverse cardiovascular events: all-cause death, stroke, pacemaker implant, myocardial infarction, paravalvular leak ≥II, and reoperation). RESULTS: After matching, there were no substantial differences between groups. The 30-day mortality was significantly lower in the sutureless valve group (sutureless valve = 1.7% vs transcatheter aortic valve implantation = 5.5%; P = .024) and the rate of permanent pacemaker implantation (sutureless valve = 5.5% vs transcatheter aortic valve implantation = 10.7%, P = .032). Stroke/transient ischemic attack cumulative incidence at 5 years was 1.4% in the sutureless valve group and 5.3% in the transcatheter aortic valve implantation group (P = .010). The incidence of perivalvular leak grade II or greater was 1.3% in the sutureless valve group and 9.8% in the transcatheter aortic valve implantation group (P < .001). At 60 months follow-up, the all-cause death rate was lower in the sutureless valve group than in the transcatheter aortic valve implantation group (sutureless valve = 16.1% ± 4.1% vs transcatheter aortic valve implantation = 28.9% ± 5.3%, P = .006), and the major adverse cardiovascular event rate was lower in the sutureless valve group (sutureless valve = 23.5% ± 4.1% vs transcatheter aortic valve implantation = 39.0% ± 5.6%, P = .002). Multivariable Cox regression identified transcatheter aortic valve implantation as an independent predictor for 5-year mortality and major adverse cardiovascular events (hazard ratio, 1.86; confidence interval, 1.09-3.18; P = .022) (hazard ratio, 1.73; confidence interval, 1.13-2.73; P = .010). CONCLUSIONS: Sutureless valves improved the outcomes of aortic stenosis in elderly patients with an intermediate risk profile when compared with transcatheter aortic valve implantation. The use of transcatheter aortic valve implantation in this subset population should be evaluated in further controlled randomized trials with sutureless valve use in a comparative cohort.

Postoperative and mid-term hemodynamic changes after replacement of the ascending aorta.

OBJECTIVES: To evaluate aortic distensibility and pulse waveform patterns associated with the ascending aortic aneurysm, and to analyze the postoperative and mid-term hemodynamic changes induced by prosthetic replacement of the ascending aorta. METHODS: Central blood pressure waves were recorded at the carotid artery level by means of a validated transcutaneous arterial tonometer in 30 patients undergoing prosthetic replacement of ascending aortic aneurysm and in 30 control patients. Measurements were obtained the day before surgery and 5 to 7 days and 16 to 20 months after surgery. RESULTS: The ascending aortic aneurysm was associated with a less steep slope of early systolic phase of the pressure curve (pulsus tardus) compared with a control group (0.54 ± 0.18 mm Hg/ms vs 0.69 ± 0.26 mm Hg/ms; P = .011). Replacing the ascending aorta with a noncompliant vascular prosthesis steepened the pulse pressure slope during the early systolic phase in the postoperative period (0.77 ± .29 mm Hg/ms), providing values comparable with those of the control group in the mid-term (0.67 ± .20 mm Hg/ms). No change in aortic stiffness was found either postoperatively or in the mid-term after ascending aorta surgical replacement (carotid-femoral pulse wave velocity: preoperative, 9.0 ± 2.6 m/s; postoperative, 9.0 ± 2.9 m/s; mid-term postoperative, 9.3 ± 2.8 m/s). CONCLUSIONS: This study does not confirm the assumption that substitution of the viscoelastic ascending aorta with a rigid prosthesis can cause serious hemodynamic alterations downstream, because we did not observe a worsening of global aortic distensibility after insertion of a rigid prosthetic aorta. The ascending aortic aneurysm is associated with a pulsus tardus.

Early outcome and mid-term survival after open arch repair using selective antegrade cerebral perfusion.

OBJECTIVES: The introduction of selective antegrade cerebral perfusion technique as method of cerebral protection improved the outcome of open arch surgery. The aim of this study was to report early outcomes using this technique. METHODS: Between 1997 and 2017, data were collected retrospectively for all patients who underwent surgical replacement of the aortic arch using selective antegrade cerebral perfusion (n = 938). To confirm the effectiveness of this cerebral protection method, early outcome and results were evaluated. RESULTS: The incidence of postoperative permanent neurological dysfunction was 6.4%. Overall hospital mortality was 11.9% (n = 112). On multivariable analysis, age >75 years, female gender, euroscore at increment of 1 point, chronic renal failure, extension of thoracic aorta replacement and CPB time emerged as independent risk factors for hospital mortality. The mid-term survival at 1, 5, 10 and 15 years was 92%, 78%, 60% and 49%, respectively. The competing risk analysis for permanent neurological dysfunction and aortic reoperations was performed excluding the patients who died during the hospital stay. The cumulative incidence of permanent neurological dysfunction and aortic reoperations was 2% at 3 years, 3% at 5 years, 6% at 10 years, 12% at 3 years, 15% at 5 years and 19% at 10 years, respectively. CONCLUSIONS: From the early 90s to the present day, the selective antegrade cerebral perfusion has confirmed to be a useful and "safe" method of brain protection in aortic arch surgery in terms of postoperative neurological complications.

Sutureless aortic valves in elderly patients with aortic stenosis and intermediate-risk profile.

AIMS: Sutureless valves became an alternative to standard bioprostheses, allowing surgeons to significantly reduce cross-clamping and extracorporeal circulation times, with a potential positive impact on major postoperative complications. The aim of this European multicentre study was to evaluate the safety and efficacy of sutureless valves in patients with an intermediate-risk profile undergoing aortic valve replacement (AVR). METHODS: We investigated early and mid-term outcomes of 518 elderly patients with aortic stenosis at intermediate-risk profile (mean STS Score 6.1 ±â€Š2%) undergoing AVR with sutureless aortic valve. Primary endpoints were 30-day mortality and freedom from all-cause death at follow-up. The secondary endpoint was survival freedom from MACCEs [all-cause death, stroke/transitory ischemic attack (TIA), bleeding, myocardial infarction, aortic regurgitation Grade II, endocarditis, reintervention and pacemaker implant; VARC 1--2 criteria]. RESULTS: Sutureless valve implantation was successfully performed in 508 patients, with a procedural success rate of 98.1% (508/518) as per VARC criteria. Concomitant myocardial revascularization [coronary artery bypass grafting (CABG)] was performed in 74 out of 518 patients (14.3%). In-hospital mortality was 1.9% (10/518). Postoperative complications included revision for bleeding (23/518; 4.4%), prolonged intubation more than 48h (4/518; 0.7%), acute renal failure (14/518; 2.7%), stroke/TIA (11/518; 2.1%), pacemaker implantation (26/518; 5.1%) and aortic regurgitation more than Grade II (7/518; 1.4%). At 48-month follow-up, Kaplan-Meier overall survival and freedom from MACCEs in patients receiving isolated AVR were 83.7% [95% confidence interval (95% CI): 81.1-86.3] and 78.4% (95% CI: 75.5-81.4), respectively, while in patients with concomitant CABG, Kaplan-Meier overall survival and freedom from MACCEs were 82.3% (95% CI: 73.3-91.3) and 79.1% (95% CI: 69.9-88.3), respectively. CONCLUSION: The use of sutureless aortic valves in elderly patients with an intermediate-risk profile provided excellent early and mid-term outcomes, providing a reliable tool in patients undergoing surgical AVR in this specific subset of population. These preliminary data need to be investigated with a TAVI control-group in further studies.

Acute Aortic Syndrome Revisited: JACC State-of-the-Art Review.

The purpose of this paper is to describe all available evidence on the distinctive features of a group of 4 life-threatening acute aortic pathologies gathered under the name of acute aortic syndrome (AAS). The epidemiology, diagnostic strategy, and management of these patients has been updated. The authors propose a new and simple diagnostic algorithm to support clinical decision making in cases of suspected AAS, thereby minimizing diagnostic delays, misdiagnoses, and unnecessary advanced imaging. AAS-related entities are reviewed, and a guideline to avoid imaging misinterpretation is provided. Centralization of patients with AAS in high-volume centers with high-volume surgeons is key to improving clinical outcomes. Thus, the role of multidisciplinary teams, an "aorta code" (streamlined emergent care pathway), and aortic centers in the management of these patients is boosted. A tailored patient treatment approach for each of these acute aortic entities is needed, and as such has been summarized. Finally, a set of prevention measures against AAS is discussed.
