Monosegmental ALPPS after Bilateral Hepatectomy.

Associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) has emerged as an alternative for patients with bilobar colorectal liver metastasis and a small future liver remnant (FLR). In cases of extensive disease, ALPPS can be performed, leaving only one segment of the liver as FLR. We describe a case of monosegmental ALPPS using segment 4 as FLR. In conclusion, ALPPS should be reserved for a selected group of patients. Monosegmental ALPPS is feasible, but should be performed by hepatobiliary surgeons in specialized centers.

Medieval orthopaedic history in Germany: Hieronymus Brunschwig and Hans von Gersdorff.

Hans von Gerssdorff and Hieronymus Brunschwig, who flourished in Germany in the latter half of the fifteenth century, have both left early printed treatises on Surgery which give excellent woodcuts showing pictures of instruments, operations, and costumes, at the end of the medieval period. Hieronymus Brunschwig or Hieronymus Brunschwygk (ca. 1450 - ca. 1512), was a German surgeon (wundartzot), alchemist and botanist. He was notable for his methods of treatment of gunshot wounds. His most influential book was the Buch der Cirurgia. Gersdorff(1455-1529) was a military surgeon who gained wide experience during 40 years of campaigning and was an expert in the treatment of battlefield injuries. His work covers anatomy, surgery, leprosy, and glossaries of anatomical terms, diseases, and medications.

Surgical aortic valve replacement in octogenarians: Single-center perioperative outcomes and five-year survival.

INTRODUCTION AND OBJECTIVES: Aortic stenosis is the most common valvular heart disease. The number of octogenarians proposed for intervention is growing due to increased lifespan. In this manuscript we aim to evaluate perioperative outcome and long-term survival after surgical aortic valve replacement (SAVR) in octogenarians, comparing patients with low surgical risk (EuroscoreII <4%) with intermediate-high risk (EuroscoreII ≥4%). METHODS: A retrospective observational single-center cohort study with 195 patients aged ≥80 years old, who underwent SAVR between 2017 and 2021, was conducted. Patients were divided into two groups according to EuroscoreII: (1) Low risk (EuroscoreII <4%) with intermediate-high risk (EuroscoreII ≥4%). Continuous variables are presented in median (IQR), analyzed using Wilcoxon rank sum test; categorical variables in percentages, analyzed using chi-squared test; and survival was analyzed by Kaplan-Meier, open cohort, and the log-rank test was performed. RESULTS: The overall median age was 82 (IQR 81-83), with 4.6% of the patients ≥85 years old. 23.6% of the patients presented EuroscoreII ≥4%. No complications were observed in 26.2%, with a significantly higher rate in intermediate-high risk patients. Postoperative need for hemodynamic support was the most frequent complication, followed by postoperative acute kidney injury and the use of blood products. Overall median ICU stay was three days (2-4) and hospital length of stay (LOS) six days (5-8). Patients with intermediate-high risk and those with complications had longer ICU LOS. At 12 months, overall survival was 96.4%, at three years 94.1% and 5 years 75.4%. Patients with low surgical risk had higher survival proportions up to 5 years. CONCLUSION: SAVR in patients ≥80 years is associated with low in-hospital mortality, although a significant proportion of patients develop complications. Long-term follow-up up to five years after surgery is acceptable in octogenarians with low surgical risk.

Non-vitamin K versus vitamin K antagonist oral anticoagulants in surgical mitral valve repair or bioprosthetic valve replacement in the first three months after surgery.

INTRODUCTION AND OBJECTIVES: Oral anticoagulation (OAC) with non-vitamin K antagonist oral anticoagulants (NOACs) after surgical mitral valve repair (MVR) or bioprosthetic valve replacement (BVR) in mitral position remains a controversial topic among the cardiovascular community, in particular in the early postoperative period. This study aimed to evaluate the efficacy and safety of NOACs in the first three months after MVR or mitral BVR compared to vitamin K antagonists (VKAs). METHODS: This was a single-center retrospective study with prospectively collected peri-intervention outcomes between 2020 and 2021. Records were retrieved and all participants were contacted by telephone. Patients were divided into groups according to OAC strategy. The primary outcome was a composite of death, rehospitalization, myocardial infarction, stroke or transient ischemic attack, systemic embolism, mitral thrombosis, or bleeding during the first three months after surgery. RESULTS: A total of 148 patients were enrolled, with a mean age of 65.5±12.2 years, 56.8% male. On discharge, 98 (66.2%) patients were on VKAs and 50 (33.8%) were on DOACs for at least three months. The primary outcome occurred in 22 (22.4%) patients in the VKA group and in three (6%) in the NOAC group (p=0.012), mainly driven by more bleeding events in the former. Independent predictors of the primary outcome were smoking (p=0.028) and OAC with VKAs at discharge, the latter predicting three times more events (p=0.046, OR 3.72, 95% CI 1.02-13.5). CONCLUSIONS: NOACs were associated with fewer events, supporting their efficacy and safety during the first three months after surgical MVR or mitral BVR.

Repair of a gigantic ascending aortic pseudoaneurysm - A challenging approach.

Aortic pseudoaneurysms can be a potentially fatal, yet rare, complication of heart surgery. Surgery is indicated but is high risk during sternotomy. Therefore, careful planning is required. We report the case of a 57-year-old patient who underwent heart surgery twice in the past and who presented with an ascending aortic pseudoaneurysm. A successful repair of the pseudoaneurysm was performed under deep hypothermia, left ventricular apical venting, periods of circulatory arrest and endoaortic balloon occlusion.

Evaluating the efficacy and safety of rivaroxaban as a warfarin alternative in chronic thromboembolic pulmonary hypertension patients undergoing pulmonary endarterectomy: A randomized clinical trial.

BACKGROUND AND AIM: Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by the obstruction of the main pulmonary artery due to thrombosis and vascular remodeling. Regarding the need for anticoagulant therapy in CTEPH patients, this study aimed to compare rivaroxaban with warfarin in terms of its efficacy and safety in patients undergoing endarterectomy surgery. METHODS: The study was a parallel clinical trial in patients who underwent endarterectomy following CTEPH. A total of 96 patients were randomly selected and assigned to two groups: warfarin-treated (control) and rivaroxaban-treated (intervention). Patients were clinically assessed for re-thrombosis, re-admission, bleeding, and mortality in the first, third, and sixth months after surgery. RESULTS: There was no significant difference in the occurrence of thrombosis between the two groups within the first, third-, and sixth-months post-surgery (p=0.52, 1, 0.38 respectively). Moreover, the mortality rate (p=0.9), bleeding rate (p=0.06), and re-admission rate (p=0.15) showed no significant differences between the two groups. CONCLUSION: Rivaroxaban may be as effective as warfarin in treating CTEPH patients after endarterectomy in the short term and can be used as an anticoagulant in these patients. However, studies with long-term follow-ups are needed to consolidate the strategy of treating these patients with rivaroxaban.

The evolution of management of type B aortic dissection in a series of 100 consecutive cases in a tertiary center.

INTRODUCTION AND OBJECTIVES: Management of aortic dissection is rapidly evolving. The present study aims to assess paradigm shifts in type B aortic dissection (TBAD) treatment modalities and their outcomes according to clinical presentation and type of treatment. We also aim to assess the impact of endovascular technology in TBAD management in order to define organizational strategies to provide an integrated cardiovascular approach. METHODS: We performed a retrospective review with descriptive analysis of the last 100 consecutive patients with TBAD admitted to the Vascular Surgery Department of Centro Hospitalar Universitário Lisboa Norte over a 16-year period. Results were stratified according to treatment modality and stage of the disease. The study was further divided into two time periods, 2003-2010 and 2011-2019, respectively before and after the introduction of a dedicated endovascular program for aortic dissections. RESULTS: A total of 100 patients (83% male; mean age 60 years) were included, of whom 59 were admitted in the acute stage (50.8% with complicated dissections). The other 41 patients were admitted for chronic dissections, most of them for surgical treatment of aneurysmal degeneration. Temporal analysis demonstrated an increase in the number of patients operated for aortic dissection, mainly due to an increase in chronic patients (33.3% in 2003-2010 vs. 64.4% in 2011-2019) and a clear shift toward endovascular treatment from 2015 onward. Overall in-hospital mortality was 14% and was significantly higher in the chronic phase (acute 5.1% vs. chronic 26.8%; OR 5.30, 95% CI 1.71-16.39; p=0.003) and in patients with aneurysmal degeneration, regardless of the temporal phase. Only one death was recorded in the endovascular group. CONCLUSION: Management of TABD carried an overall mortality of 14% during a 16-year period, but the appropriate use of endovascular technology has substantially reduced in-hospital mortality.

Reproducibility and validity of the Portuguese Edmonton Frail Scale version in cardiac surgery patients.

INTRODUCTION: Frailty is a multidimensional syndrome characterized by the loss of functional reserve, associated with higher mortality and less functional survival in cardiac surgery patients. The Edmonton Frail Scale (EFS) is a comprehensive tool devised for brief frailty detection. To the best of our knowledge, there are no culturally adapted and validated frailty screening tools that enable the identification of vulnerability domains suited for use in the preoperative setting in Portugal. This was the motivation for this study. OBJECTIVES: To assess the validity and reproducibility of the Portuguese version of the EFS. METHODS: Prospective observational study, in a sample of elective cardiac surgery patients. The Edmonton Frail Scale (EFS) translation and backtranslation were performed. Demographic and clinical data were collected, and the translated EFS translated, Geriatric Depression Scale, and Mini Mental State Examination Portuguese versions, Katz and Clinical Frailty Scales were administered. To assess validity Mann-Whitney test, Spearman's correlation coefficient, marginal homogeneity test and Kappa coefficient were employed. Reproducibility was assessed estimating kappa coefficient for the frailty diagnosis and the 11 EFS items. Intra-class correlation coefficients and the corresponding 95% confidence interval were estimated using linear mixed effects model. RESULTS: The EFS Portuguese version revealed construct validity for frailty identification, as well as criterion validity for cognition and mood domains. Reproducibility was demonstrated, with k=0.62 (95% confidence interval (CI) 0.42-0.82) and intraclass correlation (ICC)=0.94 (95% CI 0.89-0.97) in inter-observer test and k=0.48 (95% CI 0.26-0.70) and ICC=0.85 (95% CI 0.72-0.92) in intra-observer test. CONCLUSIONS: The EFS Portuguese version is valid and reproducible for use, suiting pre-operative frailty screening in a cardiac surgery setting.

Percutaneous versus surgical revascularization of unprotected left main coronary artery: Data from the Portuguese Registry of Acute Coronary Syndromes (ProACS).

BACKGROUND: In acute coronary syndromes (ACS), the optimal revascularization strategy for unprotected left main coronary artery (ULMCA) culprit lesion has been under-investigated. Therefore, we compared clinical characteristics and short- and medium-term outcomes of percutaneous and surgical revascularization in ACS. METHODS AND RESULTS: Of 31886 patients enrolled in a multicenter, national, prospective registry study between October 2010 and December 2020, 246 (0.8%) had ULMCA as a culprit lesion and underwent percutaneous coronary intervention (PCI) alone (n=133, 54%) or coronary artery bypass grafting (CABG) alone (n=113, 46%). Patients undergoing PCI presented more frequently ongoing chest pain (68% versus 41%, p<0.001) and cardiogenic shock (25% versus 1%, p<0.001). Time from admission to revascularization was higher in surgical group with a median time to CABG of 4.5 days compared to 0 days to PCI (p<0.001). Angiographic success rate was 93.2% in patients who underwent PCI. Primary endpoint (all-cause death, non-fatal reinfarction and/or non-fatal stroke during hospitalization) occurred in 15.9% of patients and was more frequent in the PCI group (p<0.001). After adjustment, surgical revascularization was associated with better in-hospital prognosis (odds ratio (OR) 0.164; 95% confidence interval (CI), 0.04-0.64; p=0.009). Similar results were achieved after propensity score matching. No difference was found at one-year all-cause death. CONCLUSION: Percutaneous coronary intervention was the most common revascularization strategy in the ACS with ULMCA culprit lesion. PCI was preferred in unstable patients and presented a high angiographic success. CABG was often delayed and preferred in low-risk patients. At one-year follow-up, PCI and CABG conferred a similar prognosis. The two approaches appear complementary in this high risk cohort.

What is the role of septal myectomy in aortic stenosis?

Asymmetric basal septal hypertrophy is present in 10% of patients with hemodynamic significant aortic valve stenosis. From the surgeon's standpoint, it represents a dilemma as it may be implicated in suboptimal short and long-term results after aortic valve replacement (AVR), but also heighten unwarranted complications at the time of surgical correction. To provide insight about the usefulness and safety of concomitant septal myectomy in this setting, we performed a literature review searching Medline from its inception to November 2020 using the Pubmed interface. Only five low evidence retrospective analyses, comprising a total of <200 patients undergoing AVR with concomitant septal myectomy, were found in the literature. In summary, routine myectomy, in the presence of suspected or directly visualized asymmetric septal hypertrophy on echocardiogram during AVR, seems to be a safe procedure, with all authors reporting a low rate or absence of complications. Overall, myectomy in this setting is associated with superior echocardiographic results concerning surrogates of LV remodelling (LVM; LVM index; LVM/height) and diastolic function (E/E'), suggesting some benefit for hemodynamic outcomes. However, to what extent hemodynamic improvement is exclusively attributable to myectomy is uncertain, as is, the clinical significance of such an improvement, with similar short and mid-term survival rates being reported.

Transapical off-pump mitral valve repair with NeoChord™ implantation: An early single-center Portuguese experience.

INTRODUCTION: Transapical off-pump NeoChord DS1000™ implantation is a minimally invasive surgical mitral valve repair (MVr) procedure to treat degenerative mitral regurgitation (MR), which is performed using the NeoChord DS1000™ system with two and three-dimensional transesophageal echocardiographic guidance on a beating heart. It has been demonstrated to be safe and effective in carefully selected patients. OBJECTIVE: The authors aim to analyze short-term clinical and echocardiographic results after mitral valve repair using the NeoChord™ system. METHODS: All patients that underwent transapical off-pump mitral valve repair with NeoChord™ implantation at our center, between December 2017 and December 2019, were included. The procedure was performed by left minithoracotomy, under general anesthesia. All patients presented severe primary MR due to flail/prolapse of one leaflet (anterior or posterior). RESULTS: Eighteen patients were included in the analysis, the mean age was 65±15 years, 72% were male. The mean EuroSCORE II was 1.9±1.6. All patients had New York Heart Association (NYHA) class ≥ II. Mean effective regurgitant orifice area was 1.0±0.4 cm2, with a mean regurgitant volume 146±42 mL, and a mean leaflet-to-annulus index of 1.29±0.14. MR was due to leaflet prolapse in 50% (N=9), and flail leaflet in 50% (N=9). Anatomic type A (isolated P2 defect) was the predominant form in 66.5% (N=12). Successful repair, defined by none, trace or mild mitral regurgitation, by implantation of two to four neochordae, was achieved in all 18 patients. No major complications arose intra-procedurally. The median follow-up was 194 days. NYHA class was ≤II in 94.5% patients at six-month follow-up, which represented a significant improvement in symptomatic status (p=0.002). At follow-up, 72% of patients (N=13) had grade ≤2 MR. There was a significant reduction in mean indexed left atrium volume (63±7 mL/m2 vs. 45±6 mL/m2, p=0.038), mean indexed left ventricular end-diastolic volume (87±7 mL/m2 vs. 79±9 ml/m2, p=0.001), and pulmonary arterial systolic pressure (44±4 vs. 31±8 mmHg, p=0.002). The re-intervention rate was 11.1% (N=2, both patients underwent reintervention, either a re-do NeoChord™ or conventional MV repair on-pump surgery). No major adverse cardiac or cerebrovascular events were registered. CONCLUSIONS: In selected patients, minimally invasive MVr using the NeoChord™ system is safe, effective and reproducible. Early clinical and echocardiographic results suggest a significant symptomatic improvement, sustained MR grade decrease, and favorable left cardiac chamber remodeling, with low re-intervention rates. These results warrant further confirmation in larger cohorts, on longer period of follow-up.

Effectiveness of preoperative breathing exercise interventions in patients undergoing cardiac surgery: A systematic review.

Postoperative pulmonary complications are a common cause of morbidity and mortality in patients undergoing cardiac surgery, leading to an increase in length of hospital stay and healthcare costs. This systematic literature review aims to determine whether patients undergoing cardiac surgery who undergo preoperative breathing exercise training have better postoperative outcomes such as respiratory parameters, postoperative pulmonary complications, and length of hospital stay. Systematic searches were performed in the CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Clinical Answers, Cochrane Database of Systematic Reviews, MEDLINE and MedicLatina databases. Studies were included if they examined adult patients scheduled for elective cardiac surgery, who underwent a preoperative breathing exercise training aimed at improving breathing parameters, preventing postoperative pulmonary complications, and reducing hospital length of stay. This systematic review was based on Cochrane and Prisma statement recommendations in the design, literature search, analysis, and reporting of the review. The search yielded 608 records. Eleven studies met the inclusion criteria. Ten studies were randomized controlled trials and one was an observational cohort study. Data from 1240 participants was retrieved from these studies and meta-analysis was performed whenever possible. A preoperative breathing intervention on patients undergoing cardiac surgery may help improve respiratory performance after surgery, reduce postoperative pulmonary complications and hospital length of stay. However, more trials are needed to support and strengthen the evidence.

Current status of the treatment of degenerative mitral valve regurgitation.

Degenerative mitral valve disease (myxomatous degeneration or fibroelastic deficiency) is the most common indication for surgical referral to treat mitral regurgitation. Mitral valve repair is the procedure of choice whenever feasible and when the results are expected to be durable. Posterior leaflet prolapse is the commonest lesion, found in up to two-thirds of patients. It is the easiest to repair, particularly when limited to one segment. In these cases, rates of repairability and procedural success approach 100%, and there is now ample evidence that the immediate and long-term results are better than those of valve replacement. Notably, minimally invasive valvular procedures, surgical or interventional, have attracted increasing interest in the last decade. When performed by experienced groups, mitral valve repair is unrivaled irrespective of the severity of lesions, from simple to complex, which leaflets are involved, and the type of degenerative involvement (myxomatous or fibroelastic). Its results should be viewed as the benchmark for other present and future technologies. By contrast, percutaneous mitral valve repair is still in its infancy and its results so far fall short of those of surgical repair. Nevertheless, continued investment in transcatheter procedures is of great importance to enable development and improved accessibility, particularly for patients who are considered unsuitable for surgery. In this review, we analyze the current status of management of degenerative mitral valve disease, discussing mitral valve anatomy and pathology, indications for intervention, and current surgical and transcatheter mitral valve procedures and results.

Acquired anomalies of the coronary arteries after arterial switch operation. Usefulness of coronary computed tomography angiography and impact on follow-up.

INTRODUCTION: Mortality and morbidity in patients with transposition of the great arteries after an arterial switch operation depends mainly on the status of coronary perfusion. Coronary computed tomography angiography (CCTA) provides accurate information on coronary morphology, however its use in these patients is not yet routine procedure. OBJECTIVE: We sought to assess its accuracy to identify acquired coronary anomalies in this population, compared to conventional angiography in a subset of patients, and assess its impact on postoperative management. METHODS: Retrospective analysis of clinical data on transposition of the great arteries in patients who underwent CCTA between January 2013 and September 2017. RESULTS: Between January 2013 and September 2017, 18 patients underwent CCTA. Seven patients (39%) disclosed iatrogenic coronary lesions (stenosis 1; kinking 2, occlusion 1; filiform coronary 3). The exam was performed in 78% of patients due to suggestion of myocardial ischemia (symptoms or altered exams). Only 16% needed to undergo additional exams, and in four patients the CCTA result modified therapeutic management. Conventional coronary angiography was also performed in 10 patients (55%), and in three cases, the results were discordant with underestimation or non-identification of coronary lesions on conventional angiography. The medium radiation dose used was 2.4 mSv and no complications after CT were reported. CONCLUSION: CCTA accurately identified iatrogenic postoperative coronary lesions and it has proven to be superior to conventional angiography in this population. It should be performed routinely in this group of patients, even in the absence of symptoms.

Algorithm for the treatment of external nasal valve insufficiency.

INTRODUCTION: Nasal obstruction is one of the most prevalent complaints in the population. The main causes of nasal obstruction are inflammatory, infectious or anatomical alterations. Anatomical alterations include nasal septum deviation, turbinate hypertrophy, and nasal valve insufficiency (external and/or internal). The diagnosis of nasal valve insufficiency remains a clinical one and is based on inspection and palpation of the nose, evaluating both its static and dynamic functions. The literature presents several options for the correction of external nasal valve insufficiency. These are chosen according to the choice and experience of each surgeon. OBJECTIVE: To create a practical algorithm for the treatment of external nasal valve insufficiency that can guide nasal surgeons in their choice of treatment for the different anatomical alterations found in patients with these disorders. METHODS: We used the treatment options found in the literature and correlated them with our surgical options for each type of anatomical alteration found. Therefore, we used basically three parameters related to physical examination findings (degree of insufficiency and characteristics of the lower lateral cartilage) and the patient's complaint (present or absent aesthetic complaint regarding the nasal tip). RESULT: A practical algorithm was developed for the treatment of external nasal valve insufficiency according to the degree of insufficiency (mild-to-moderate or severe), aesthetic complaint of the nasal tip (present or absent) and characteristics of the lower lateral cartilage (size and orientation). CONCLUSION: Through this simple algorithm, one can use each type of graft and/or maneuver according to the patients' complaints and the anatomical alterations found.

Effect of infiltrating nasal packing with local anesthetics in postoperative pain and anxiety following sinonasal surgeries: a systemic review and meta-analysis.

INTRODUCTION: Packing of the nasal cavity has traditionally been used for postoperative bleeding control and decreasing synechia formation in patients undergoing nasal surgeries. Although absorbable nasal packing has been gaining popularity in the recent years, nonabsorbable nasal packing is still often used in nasal surgeries in various parts of the world. It is known to be associated with pain and discomfort especially upon and during removal, and previous reviews have only evaluated the effects of local anesthetic infiltration of nasal packing in septal surgeries. OBJECTIVE: To evaluate the effect of infiltrating nasal packing with local anesthetics in postoperative pain and anxiety following sinonasal surgeries MATERIALS AND METHODS: We searched the PubMed and Embase databases from their earliest record to April 27, 2019, randomized controlled trials and prospective controlled trials for review, and included only randomized controlled trials for data analysis. We included studies using topical anesthetics-infiltrated nasal packing following sinonasal surgeries and evaluated the effectiveness compared to placebo packing in pain reduction during postoperative follow up, as well as the effectiveness in anxiety reduction. RESULTS: Among 15 studies included for review, 9 studies involving 765 participants contributed to the meta-analysis. In terms of pain reduction, our analysis showed significant standard mean differences regarding effectiveness at postoperative 1, 12, 24 h interval for all surgical groups combined, in the sinus surgery group, as well as during nasal packing removal. There was no consistent evidence to support the effectiveness in anxiety reduction. CONCLUSIONS: Our study supports anesthetics infiltration of nasal packing as an effective method in managing pain in patients with nasal packing after sinonasal surgeries. However, the level of evidence is low. More high-quality randomized controlled trials are needed to establish its effectiveness in reducing anxiety. We believe this review is of great clinical significance due to the vast patient population undergoing sinonasal surgeries. Postoperative local hemorrhage remains the greatest concern for ear nose and throat surgeons due to the rich vasculature of the nose and sinuses. Sinonasal packing provides structural support and serves as an important measure for hemostasis and synechia formation. Although absorbable packing has been gaining popularity in the recent years, nonabsorable packing materials are still used in many countries due to lower cost. Infiltration of nasal packing with local anesthetic provides a solution to the discomfort, nasal pressure and nasal pain experienced commonly by the patients as evidenced by our analysis.

Cardiac surgery in infective endocarditis and predictors of in-hospital mortality. / Cirurgia cardíaca na endocardite infeciosa e preditores da mortalidade intra­hospitalar.

INTRODUCTION: Infective endocarditis (IE) is a serious disease with significant in-hospital mortality (15-30%) despite advances in medical and surgical therapy. AIMS: To perform a clinical characterization of patients undergoing cardiac surgery for IE and to identify factors that predict in-hospital mortality. METHODS: We retrospectively analyzed 145 patients with IE admitted between January 2006 and October 2017. RESULTS: The median age was 72 years. IE was acquired mainly in the community (69%), and involved the native aortic valve in 54% of patients, biological prosthetic valves in 22.1% and mechanical valves in 10.3%. Staphylococcus spp. (31.0%) were the most frequent etiological agents. Cardiac surgery was emergent in 29 patients, urgent in 108, and elective in eight. The main indications were heart failure (57.9%), large vegetations (20%), systemic embolism (17.2%) and valve dysfunction (15.2%). Overall, biological valves were implanted in 62.1% of patients and mechanical valves in 37.2%. A total of 19 patients (13.1%) died. Predictors of mortality were preoperative atrial fibrillation and lower left ventricular ejection fraction, postoperative severe valve regurgitation associated with cardiogenic shock, sepsis, septic shock associated with cardiogenic shock, cardiac tamponade, need for renal replacement therapy and, although without statistical significance, emergent surgery. CONCLUSIONS: There is a need for better indicators to enable early identification of surgical candidates for IE, implementation of a heart team, and better surgical strategies, including more rapid intervention, more specific postoperative care, and optimal antibiotic therapy.

Levoatrial cardinal vein with left-to-right shunt in a neonate: Multi-imaging diagnosis.

We present a rare case of a levoatrial cardinal vein identified during the work-up of a patient with coarctation of the aorta. Early diagnosis and repair in the neonatal period prevented future manifestations of left-to-right shunt and the need for reoperations, in contrast with the later-age presentation of this congenital anomaly. An integrative approach was crucial for prompt detection, intraoperative confirmation and complete one-stage repair.
