RESUMO
BACKGROUND: Over the past 25 years, diagnosis and therapy for acute aortic dissection (AAD) have evolved. We aimed to study the effects of these iterative changes in care. METHODS: Patients with nontraumatic AAD enrolled in the International Registry of Acute Aortic Dissection (61 centers; 15 countries) were divided into time-based tertiles (groups) from 1996 to 2022. The impact of changes in diagnostics, therapeutic care, and in-hospital and 3-year mortality was assessed. Cochran-Armitage trend and Jonckheere-Terpstra tests were conducted to test for any temporal trend. RESULTS: Each group consisted of 3785 patients (mean age, ≈62 years old; ≈65.5% males); nearly two-thirds had type A AAD. Over time, the rates of hypertension increased from 77.8% to 80.4% (P=0.002), while smoking (34.1% to 30.6%, P=0.033) and atherosclerosis decreased (25.6%-16.6%; P<0.001). Across groups, the percentage of surgical repair of type A AAD increased from 89.1% to 92.5% (P<0.001) and was associated with decreased hospital mortality (from 24.1% in group 1 to 16.7% in group 3; P<0.001). There was no difference in 3-year survival (P=0.296). For type B AAD, stent graft therapy (thoracic endovascular aortic repair) was used more frequently (22.3%-35.9%; P<0.001), with a corresponding decrease in open surgery. Endovascular in-hospital mortality decreased from 9.9% to 6.2% (P=0.003). As seen with the type A AAD cohort, overall 3-year mortality for patients with type B AAD was consistent over time (P=0.084). CONCLUSIONS: Over 25 years, substantial improvements in-hospital survival were associated with a more aggressive surgical approach for patients with type A AAD. Open surgery has been partially supplanted by thoracic endovascular aortic repair for complicated type B AAD, and in-hospital mortality has decreased over the time period studied. Postdischarge survival for up to 3 years was similar over time.
RESUMO
Background: EuroSCORE II (ES2) is a reliable tool for preoperative cardiac surgery mortality risk prediction; however, a patient's age, a surgical procedure's weight and the new devices available may cause its accuracy to drift. We sought to investigate ES2 performance related to the surgical risk and late mortality estimation in patients who underwent aortic valve replacement (AVR) with sutureless valves. Methods: Between 2012 and 2021, a total of 1126 patients with isolated aortic stenosis who underwent surgical AVR by means of sutureless valves were retrospectively collected from six European centers. Patients were stratified into three groups according to the EuroSCORE II risk classes (ES2 < 4%, ES2 4-8% and ES2 > 8%). The accuracy of ES2 in estimating mortality risk was assessed using the standardized mortality ratio (O/E ratio), ROC curves (AUC) and Hosmer-Lemeshow (HL) test for goodness-of-fit. Results: The overall observed mortality was 3.0% (predicted mortality ES2: 5.39%) with an observed/expected (O/E) ratio of 0.64 (confidential interval (CI): 0.49-0.89). In our population, ES2 showed a moderate discriminating power (AUC 0.65, 95%CI 0.56-0.72, p < 0.001; HL p = 0.798). Good accuracy was found in patients with ES2 < 4% (O/E ratio 0.54, 95%CI 0.23-1.20, AUC 0.75, p < 0.001, HL p = 0.999) and for patients with an age < 75 years (O/E ratio 0.98, 95%CI 0.45-1.96, AUC 0.76, p = 0.004, HL p = 0.762). Moderate discrimination was observed for ES2 in the estimation of long-term risk of mortality (AUC 0.64, 95%CI: 0.60-0.68, p < 0.001). Conclusions: EuroSCORE II showed good accuracy in patients with an age < 75 years and patients with ES2 < 4%, while overestimating risk in the other subgroups. A recalibration of the model should be taken into account based on the complexity of actual patients and impact of new technologies.
RESUMO
Mitral regurgitation (MR) is a broadly diffuse valvular heart disease (VHD) with a significant impact on the healthcare system and patient prognosis. Transcatheter mitral valve interventions (TMVI) are now well-established techniques included in the therapeutic armamentarium for managing patients with mitral regurgitation, either primary or functional MR. Even if the guidelines give indications regarding the correct management of this VHD, the wide heterogeneity of patients' clinical backgrounds and valvular and heart anatomies make each patient a unique case, in which the appropriate device's selection requires a multimodal imaging evaluation and a multidisciplinary discussion. Proper pre-procedural evaluation plays a pivotal role in judging the feasibility of TMVI, while a cooperative work between imagers and interventionalist is also crucial for procedural success. This manuscript aims to provide an exhaustive overview of the main parameters that need to be evaluated for appropriate device selection, pre-procedural planning, intra-procedural guidance and post-operative assessment in the setting of TMVI. In addition, it tries to give some insights about future perspectives for structural cardiovascular imaging.

Objective: In heritable aortic diseases, different vascular involvement may occur with potential variable implications in aortic dilation/dissection risk. This study aimed to analyze the aortic anatomy of individuals with Marfan syndrome and Loeys-Dietz syndrome to identify possible morphological differences. Methods: Computed tomography and magnetic resonance imaging of the thoracoabdominal aorta from the proximal supra-aortic vessels to the femoral bifurcation level of 114 patients with Marfan and Loeys-Dietz syndromes and 20 matched control subjects were examined. Aortic diameters, areas, length, and tortuosity were measured in different aortic segments using specific vessel analysis software. Results: Patients with Marfan syndrome showed a higher prevalence of ascending aorta and aortic root dilation (P = .011), larger and longer aortic roots (P = .013) with pear-shaped phenotype, larger isthmus/descending aorta diameter ratio (P = .015), and larger suprarenal aorta and iliac arteries. Patients with Loeys-Dietz syndrome showed longer indexed segments and a significantly longer arch (P = .006) with type 2/3 arch prevalence (P = .097). Measurement ratios analysis provided cut-off values (aortic root to ascending aorta length/aortic root diameter, aortic root/sinotubular junction, aortic root/ascending aorta diameter) differentiating patients with Marfan syndrome from patients with Loeys-Dietz syndrome, even in the early stage of the disease. Conclusions: Both syndromes show peculiar anatomic patterns at different aortic levels irrespective of aortic dilation and disease severity. These features may represent the expression of different genetic mutations on aortic development, with a potential impact on prognosis and possibly contributing to better management of the diseases. The systematic adoption of whole body imaging with magnetic resonance or computed tomography should always be considered, because they allow a complete vascular assessment with practical indicators of differential diagnosis.
RESUMO
INTRODUCTION: Type A acute aortic dissection (TA-AAD) is a great challenge for aortic surgeons. The establishment of a standardized surgical approach, particularly the determination of whether and when to address the aortic arch and the distal aorta in the same operation as the proximal aorta, is still unclear. AREAS COVERED: Frozen elephant trunk (FET) has emerged as a valuable treatment for TA-AAD over the last decade. Here, we discuss the fundamentals and pitfalls of frozen elephant trunk procedures and present the latest innovations. EXPERT OPINION: FET has the potential to simplify arch reconstruction in patients with complex arch tears and rupture, optimize perfusion in the distal true lumen for those with a compressed true lumen and malperfusion, address distal reentry tears, and promote false lumen thrombosis and late aortic remodeling. Nevertheless, FET is still associated with non-negligible mortality and morbidity rates. Patient selection, surgical expertise, and postoperative care remain crucial determinants in ensuring successful outcomes. Recent innovations in FET surgery involve the development of techniques to minimize or avoid hypothermic circulatory arrest and new FET devices with different arch branch configurations aiming to facilitate subsequent aortic reinterventions. We believe that both these advancements have the potential to improve patient outcomes.
RESUMO
Background and Objectives: Determinants of long-term outcomes after surgery for native mitral valve endocarditis have not been thoroughly investigated. The aim of this study was to assess anatomical, disease, and surgical risk factors for long-term mortality and need of reintervention, in patients undergoing mitral valve surgery for active endocarditis. Materials and Methods: Patients who underwent surgery for active native mitral valve endocarditis at three academic centres, between 2000 and 2022, were analysed. The primary outcome was long-term survival. The secondary outcome was the freedom from mitral reoperation. Survival curves were constructed with Kaplan-Meier methodology. Multivariable Cox regression was used to identify demographic, anatomical, disease, and surgical factors associated with late mortality and reoperation. Results: 335 consecutive patients with active mitral endocarditis were analysed. Two hundred and one patients (70.5%) had infection confined to the valve cusp whereas 89 (25.6%) had invasive disease extended to the annulus and surrounding tissues. Preoperative neurological events occurred at the diagnosis in 52 cases. Streptococci were the most common causative organisms followed by Staphylococcus aureus, Coagulase-negative Staphylococcus, and Enterococcus. Valve repair was performed in 108 patients (32.2%). Survival at 5 and 10 years was 70.1% and 59.2%, respectively. Staphylococcus emerged as an independent predictor of late mortality, along with age, chronic obstructive pulmonary disease, and previous cardiac surgery. Survival was considerably reduced in patients with S. aureus compared with those without (log rank p < 0.001). The type of surgery (repair vs. replacement) did not emerge as a risk factor for late mortality and reoperation. Seventeen patients underwent mitral reoperation during the follow-up. The 5- and 10-year freedom from reoperation was 94.7% and 91.8%, respectively. Conclusions: Active mitral valve endocarditis remains a life-threatening disease with impaired survival. While lesion characteristics influenced surgical decision-making and intraoperative management, their impact on long-term survival and freedom from reintervention appears to be moderated by other factors such as infecting pathogens and patient comorbidities.

Background: Enhanced recovery after surgery (ERAS) protocols aim to reduce postoperative complications and promote earlier recovery. Although it is well established in noncardiac surgery fields, the ERAS approach has only recently been adopted in cardiac surgery. The aim of this review is to evaluate the status and implementation of ERAS protocols in patients undergoing heart valve surgery and to summarise associated clinical results. Methods: A literature search for the period January 2015 and January 2024 was performed through online databases. Clinical studies (randomised controlled trials and cohort studies) on patients undergoing heart valve surgical procedures and comparing ERAS and conventional approaches were included. The data extracted covered studies and populations characteristics, early outcomes and the features of each ERAS protocol. Results: There were 14 studies that fulfilled the final search criteria and were ultimately included in the review. Overall, 5142 patients were identified in the 14 studies, with 2501 in ERAS groups and 2641 patients who were representative of control groups. Seven experiences exclusively included patients who underwent heart valve surgery. Twelve out of fourteen protocols involved multiple interventions from the preoperative to postoperative phase, while two studies reported actions limited to intraoperative and postoperative care. We found high heterogeneity among the included protocols regarding key actions targeted for improvement and measured outcomes. All the studies showed that ERAS pathways can be safely adopted in cardiac surgery and in most of the experiences were associated with shorter mechanical ventilation time, reduced postoperative opioid use and reduced ICU and hospital stays. Conclusions: As demonstrated in noncardiac surgery, the adoption of structured ERAS protocols has the potential to improve results in patients undergoing heart valve surgery. Further evidence based on larger populations is needed, including more homogenous pathways and reporting further outcomes in terms of patient satisfaction, recovery and quality of life after surgery.
RESUMO
Background: The management of cardiogenic shock (CS) after ACS has evolved over time, and the development of a multidisciplinary team-based approach has been shown to improve outcomes, although mortality remains high. Methods: All consecutive patients with ACS-CS admitted at our CICU from March 2012 to July 2021 were included in this single-center retrospective study. In 2019, we established a "shock team" consisting of a cardiac intensivist, an interventional cardiologist, an anesthetist, and a cardiac surgeon. The primary outcome was in-hospital mortality. Results: We included 167 patients [males 67%; age 71 (61-80) years] with ischemic CS. The proportion of SCAI shock stages from A to E were 3.6%, 6.6%, 69.4%, 9.6%, and 10.8%, respectively, with a mean baseline serum lactate of 5.2 (3.1-8.8) mmol/L. Sixty-six percent of patients had severe LV dysfunction, and 76.1% needed ≥ 1 inotropic drug. Mechanical cardiac support (MCS) was pursued in 91.1% [65% IABP, 23% Impella CP, 4% VA-ECMO]. From March 2012 to July 2021, we observed a significative temporal trend in mortality reduction from 57% to 29% (OR = 0.90, p = 0.0015). Over time, CS management has changed, with a significant increase in Impella catheter use (p = 0.0005) and a greater use of dobutamine and levosimendan (p = 0.015 and p = 0.0001) as inotropic support. In-hospital mortality varied across SCAI shock stages, and the SCAI E profile was associated with a poor prognosis regardless of patient age (OR 28.50, p = 0.039). Conclusions: The temporal trend mortality reduction in CS patients is multifactorial, and it could be explained by the multidisciplinary care developed over the years.
RESUMO
BACKGROUND: Cannulation strategy in acute type A dissection (ATAD) varies widely without known gold standards. This study compared ATAD outcomes of axillary vs femoral artery cannulation in a large cohort from the International Registry of Acute Aortic Dissection (IRAD). METHODS: The study retrospectively reviewed 2145 patients from the IRAD Interventional Cohort (1996-2021) who underwent ATAD repair with axillary or femoral cannulation (axillary group: n = 1106 [52%]; femoral group: n = 1039 [48%]). End points included the following: early mortality; neurologic, respiratory, and renal complications; malperfusion; and tamponade. All outcomes are presented as axillary with respect to femoral. RESULTS: The proportion of patients younger than 70 years in both groups was similar (n = 1577 [74%]), as were bicuspid aortic valve, Marfan syndrome, and previous dissection. Patients with femoral cannulation had slightly more aortic insufficiency (408 [55%] vs 429 [60%]; P = .058) and coronary involvement (48 [8%] vs 70 [13%]; P = .022]. Patients with axillary cannulation underwent more total aortic arch (156 [15%] vs 106 [11%]; P = .02) and valve-sparing root replacements (220 [22%] vs 112 [12%]; P < .001). More patients with femoral cannulation underwent commissural resuspension (269 [30.9%] vs 324 [35.3%]; P = .05). Valve replacement rates were not different. The mean duration of cardiopulmonary bypass was longer in the femoral group (190 [149-237] minutes vs 196 [159-247] minutes; P = .037). In-hospital mortality was similar between the axillary (n = 165 [15%]) and femoral (n = 149 [14%]) groups (P = .7). Furthermore, there were no differences in stroke, visceral ischemia, tamponade, respiratory insufficiency, coma, or spinal cord ischemia. CONCLUSIONS: Axillary cannulation is associated with a more stable ATAD presentation, but it is a more extensive intervention compared with femoral cannulation. Both procedures have equivalent early mortality, stroke, tamponade, and malperfusion outcomes after statistical adjustment.

INTRODUCTION: Postoperative delirium (POD) has a major impact on patient recovery after cardiac surgery. Although its pathophysiology remains unclear, there could be a correlation between cerebral blood flow (CBF) variations during cardio-pulmonary bypass (CPB) and POD. Our study aimed to evaluate whether variations in on-pump CBF, compared to pre-anesthesia and pre-CPB values, are associated with POD following coronary artery bypass grafting (CABG) surgery. METHODS: This prospective observational cohort study included 95 adult patients undergoing elective on-pump CABG surgery. Right middle cerebral artery blood flow velocity (MCAV) was assessed using Transcranial Doppler before anesthesia induction, before CPB and every fifteen minutes during CPB. Pre-anesthesia and pre-CPB values were chosen as baselines. Individual values, measured during CPB, were converted as percentage changes relative to these baselines and named as %MCAV0 and %MCAV1, respectively. POD was assessed using the Confusion Assessment Method for ICU (CAM-ICU) during the first 48 post-operative hours and with the 3-Minute Diagnostic Interview for Confusion Assessment Method (3D-CAM) on the fifth post-surgical day. RESULTS: Overall POD incidence was 17.9%. At 30 minutes of CPB, %MCAV0 was higher in POD group than in no-POD group (p = .05). %MCAV0 at 45 minutes of CPB was significantly higher in POD group (87 (±17) %) than in no-POD group (68 (±24) %), p = .04. %MCAV1 at 30 and 45 minutes of CPB were higher in POD group than in no-POD group, at the limit of statistical significance. We found %MCAV1 > 100% in POD group, but not in no-POD group. CONCLUSIONS: Significant differences in %MCAV0 became evident after 30 minutes of CPB, whereas differences in %MCAV1 at 45 minutes of CPB were at limit of statistical significance. In POD group %MCAV1 was higher than 100% at 30 and 45 minutes of CPB, which is supposed to be a sign of cerebral hyperperfusion. Monitoring CBF during CPB could have prognostic value for POD.
RESUMO
AIMS: The clinical benefits of mitral valve repair over replacement in the setting of mitral infective endocarditis are not clearly established. METHODS: Data of patients who underwent cardiac surgery for infective endocarditis over a 20-year period (2001-2021) at two cardiac centres were reviewed. Among them, 282 patients underwent native mitral valve surgery and were included in the study. Nearest-neighbour propensity-score matching was performed to account for differences in patients' profile between the repair and replacement subgroups. RESULTS: Mitral valve replacement was performed in 186 patients, while in 96 cases patients underwent mitral valve repair. Propensity match analysis provided 89 well matched pairs. Mean age was 60â±â15âyears; 75% of the patients were male. Mitral valve replacement was more commonly performed in patients with involvement of both mitral leaflets, commissure(s) and mitral annulus. Patients with lesion(s) limited to P2 segment formed the majority of the cases undergoing mitral valve repair. There was no difference in terms of microbiological findings. In-hospital mortality was 7% with no difference between the repair and the replacement cohorts. Survival probabilities at 1, 5 and 10 years were 88%, 72% and 68%, respectively after mitral repair, and 88%, 78% and 63%, respectively after mitral replacement (log-rank P â=â0.94). CONCLUSIONS: Mitral valve repair was more commonly performed in patients with isolated single leaflet involvement and provided good early and 10-year outcomes. Patients with annular disruption, lesion(s) on both leaflets and commissure(s) were successfully served on early and mid-term course by mitral valve replacement.

Objective: Randomized evidence suggests a high risk of pacemaker implantation for patients undergoing mitral valve (MV) surgery with concomitant tricuspid valve repair (cTVR). We investigated the impact of cTVR on outcomes in the Mini-Mitral International Registry. Methods: From 2015 to 2021, 7513 patients underwent minimally invasive MV with or without cTVR in 17 international centers (MV: n = 5609, cTVR: n = 1113). Propensity matching generated 1110 well-balanced pairs. Multivariable analysis was applied. Results: Patients with cTVR were older and had more comorbidities. Propensity matching eliminated most differences except for more TR in patients who underwent cTVR (77.2% vs 22.1% MV, P < .001). Mean matched age was 71 years, and 45% were male. European System for Cardiac Operative Risk Evaluation II was still 2.68% (interquartile range [IQR], 0.80-2.63) vs 1.9% (IQR, 1.12-3.9) in matched MV (P < .001). MV replacement (30%) and atrial fibrillation surgery (32%) were similar in both groups. Cardiopulmonary bypass (161 minutes [IQR, 133-203] vs MV: 130 minutes [IQR, 103-166]; P < .001) and crossclamp times (93 minutes [IQR, 66-123] vs MV: 83 minutes [IQR, 64-107]; P < .001) were longer with cTVR. Although in-hospital mortality was similar (cTVR: 3.3% vs MV: 2.2%; P = .5), postoperative pacemaker implantations (9% vs MV: 5.8%; P = .02), low cardiac output syndrome (7.7% vs MV: 4.4%; P = .02), and acute kidney injury (13.8% vs MV: 10%; P = .01) were more frequent with cTVR. cTVR eliminated relevant TR in most patients (greater-than-moderate TR: 6.8%). Multivariable analysis identified MV replacement, atrial fibrillation, and cTVR as risk factors of postoperative pacemaker implantation. Conclusions: cTVR in minimally invasive MV surgery is an independent risk factor for pacemaker implantation in this international registry. It is also associated with more bleeding, low output syndrome, and acute kidney injury. It remains unclear whether technical or patient factors (or both) explain these differences.
RESUMO
OBJECTIVES: Few data are available regarding early extubation after mitral valve surgery. We sought to assess the impact of an enhanced recovery after surgery-based protocol-ultra-fast-track protocol-in patients undergoing minimally invasive transaxillary mitral valve surgery. METHODS: Data of patients who underwent transaxillary mitral valve surgery associated with ultra-fast-track protocol between 2018 and 2023 were reviewed. We compared preoperative, intraoperative and postoperative data of patients who had fast-track extubation (≤6 h since the end of the procedure) and non-fast-track extubation (>6 h) and, within the fast-track group, patients who underwent on-table extubation and patients who were extubated in intensive care unit within 6 h. Multivariable logistic regression was used to study the association of extubation timing and intensive care unit stay, postoperative stay and discharge home. RESULTS: Three hundred fifty-six patients were included in the study. Two hundred eighty-two patients underwent fast-track extubation (79%) and 160 were extubated on table (45%). We found no difference in terms of mortality and occurrence of major complications (overall mortality and cerebral stroke 0.3%) according to the extubation timing. Fast-track extubation was associated with shorter intensive care unit stay, discharge home and discharge home within postoperative day 7 when compared to non-fast-track extubation. Within the fast-track group, on-table extubation was associated with intensive care unit stay ≤1 day and discharge home within postoperative day 7. CONCLUSIONS: Fast-track extubation was achievable in most of the patients undergoing transaxillary minimally invasive mitral valve surgery and was associated with higher rates of day 1 intensive care unit discharge and discharge home. On-table extubation was associated with further reduced intensive care unit stay and hospitalization.

INTRODUCTION: Vacuum assisted venous drainage (VAVD) is widely adopted in minimally invasive cardiac surgery. VAVD enables the advantage of using smaller cannulae in a reduced surgical field while allowing satisfactory drainage and pump flow. The production of gaseous micro-emboli is a recognized risk associated with VAVD, however no difference in clinical endpoints have been reported between patients operated on with gravity venous drainage (GVD) or with VAVD. Due to the paucity of data on selected surgical populations, we sought to evaluate the early outcomes of patients undergoing isolated aortic valve replacement using VAVD or GVD. METHODS: Data on 521 patients between 09/2016 and 09/2022 were retrieved from our internal database. Patients were divided into two groups according to use VAVD or GVD. A propensity match analysis was performed to account for difference between the two groups. RESULTS: The propensity match provided two well balanced cohorts with 129 patients each. A minimally invasive access was used in 97% of the cases in VAVD group vs 98% in GVD group (p = .68). Mean cardiopulmonary by-pass (CPB) time was 71 vs 73 min (p = .74), respectively. There was no difference in lactates peak (p = .19) and urine output during CPB (p = .74). We registered two in-hospital deaths in VAVD cohort (1.6%) vs. no mortality in GVD group (p = .5). Postoperative cerebral stroke occurred in 1 patient in GVD cohort vs. 0 in VAVD (p = 1). Severe postoperative acute kidney injury complicated the course in 16 patients in GVD group and in 5 patients who had VAVD (p = .012). VAVD was associated with a higher number of patients with elevated postoperative AST (p = .07) and Troponin I (p = .01) values. CONCLUSIONS: The use of VAVD during isolated aortic valve replacement was not associated with increased risks of postoperative complications and in-hospital mortality with results that were at least similar to those registered in a matched cohort of patients operated on with GVD.
RESUMO

RESUMO
We reported a case of non-bacterial thrombotic endocarditis (NBTE) in a 37-year-old woman who presented with signs and symptoms of cardio-embolic cerebral stroke caused by a prothrombotic state due to underlying advanced uterine cancer. Multimodal imaging, including 3D-ecocardiography, as well as laboratory and cultural tests, were critical in making the diagnosis. After starting anticoagulation therapy with low molecular weight heparin (LMWH), the patient underwent surgical aortic valve replacement due to worsening aortic valve function, initial left ventricle enlargement, increasing dimensions, and mobility of vegetations. Unfortunately, vegetations relapsed on the aortic valve bio-prosthesis as well as the mitral leaflets, resulting in a final picture of multi-valve NBTE. The fatal outcome was due to a massive multiple limb embolism, which resulted in leg amputations and septical complications. Starting with the case, we present a brief overview of the pathology's presentation, treatment, management, and prognosis, as well as the diagnostic work-up.
RESUMO
OBJECTIVES: The aim of this study was to examine the incidence and predictors of stroke after minimally invasive mitral valve surgery (mini-MVS) and to assess the role of preoperative CT scan on surgical management and neurological outcomes in the large cohort of Mini-Mitral International Registry. METHODS: Clinical, operative and in-hospital outcomes in patients undergoing mini-MVS between 2015 and 2021 were collected. Univariable and multivariable analyses were used to identify predictors of stroke. Finally, the impact of preoperative CT scan on surgical management and neurological outcomes was assessed. RESULTS: Data from 7343 patients were collected. The incidence of stroke was 1.3% (n = 95/7343). Stroke was associated with higher in-hospital mortality (11.6% vs 1.5%, P < 0.001) and longer intubation time, ICU and hospital stay (median 26 vs 7 h, 120 vs 24 h and 14 vs 8 days, respectively). On multivariable analysis, age (odds ratio 1.039, 95% confidence interval 1.019-1.060, P < 0.001) and mitral valve replacement (odds ratio 2.167, 95% confidence interval 1.401-3.354, P < 0.001) emerged as independent predictors of stroke. Preoperative CT scan was made in 31.1% of cases. These patients had a higher risk profile and EuroSCORE II (median 1.58 vs 1.1, P < 0.001). CT scan influenced the choice of cannulation site, being ascending aorta (18.5% vs 0.5%, P < 0.001) more frequent in the CT group and femoral artery more frequent in the no CT group (97.8% vs 79.7%, P < 0.001). No difference was found in the incidence of postoperative stroke (CT group 1.5, no CT group 1.4%, P = 0.7). CONCLUSIONS: Mini-MVS is associated with a low incidence of stroke, but when it occurs it has an ominous impact on mortality. Preoperative CT scan affected surgical cannulation strategy but did not led to improved neurological outcomes.

BACKGROUND: Recent randomized controlled trials showed comparable short-term outcomes of transcatheter aortic valve implantation versus surgical aortic valve replacement in intermediate and low-risk patients. However, independent studies comparing transcatheter aortic valve implantation results versus surgical aortic valve replacement at 5 years showed worsening outcomes in patients treated with transcatheter aortic valve implantation. The aim of this study was to analyze mid- to long-term outcomes of patients with isolated aortic stenosis and an intermediate-risk profile who underwent aortic valve replacement using a sutureless valve versus transcatheter aortic valve implantation. METHODS: This retrospective multi-institutional European study investigated 2,123 consecutive patients with isolated aortic stenosis at intermediate risk profile treated with sutureless aortic valve replacement (824 patients) or transcatheter aortic valve implantation (1,299 patients) from 2013 to 2020. After 1:1 propensity score matching, 2 balanced groups of 517 patients were obtained. Primary endpoints were as follows: 30 days, late all-cause, and cardiac-related mortality. Secondary endpoints included major adverse cardiocerebrovascular events (all-cause death, stroke/transient ischemic attack, endocarditis, reoperation, permanent pacemaker implantation, and paravalvular leak grade ≥2). RESULTS: Median follow-up was 4.3 years (interquartile range 1.1-7.4 years). Primary endpoints were as follows-30-day mortality sutureless aortic valve replacement: 2.13% versus transcatheter aortic valve implantation: 4.64% (P = .026), all-cause mortality sutureless aortic valve replacement: 36.7% ± 7.8% vs transcatheter aortic valve implantation: 41.8% ± 8.2% (P = .023), and cardiac-related mortality sutureless aortic valve replacement: 10.2% ± 2.8% vs transcatheter aortic valve implantation: 19.2% ± 3.5%;(P = .00043) at follow-up. Secondary endpoints were as follows-major adverse cardiocerebrovascular events in the sutureless aortic valve replacement group: 47.2% ± 9.0% versus transcatheter aortic valve implantation: 57.3% ± 7.5% (P < .001). In particular, the incidence of permanent pacemaker implantation (sutureless aortic valve replacement: 6.38% versus transcatheter aortic valve implantation: 11.8% [P = .002]) and paravalvular leak ≥2 (sutureless aortic valve replacement: 0.97% versus transcatheter aortic valve implantation: 4.84% [P = .001]) was significantly higher in transcatheter aortic valve implantation group. At Multivariable Cox regression analysis, paravalvular leak ≥2 (hazard ratio: 1.63%; 95% confidence interval: 1.06-2.53, P = .042) and permanent pacemaker implantation (hazard ratio: 1.49%; 95% confidence interval: 1.02-2.20, P = .039) were identified as predictors of mortality. CONCLUSION: Sutureless aortic valve replacement showed a significantly lower incidence of all-cause mortality, cardiac-related death, permanent pacemaker implantation, and paravalvular leak than transcatheter aortic valve implantation. Moreover, permanent pacemaker implantation and paravalvular leak negatively affected survival in patients treated for isolated aortic stenosis.
