RESUMEN

BACKGROUND: Streptococci are a common cause of infective endocarditis (IE). We aimed to evaluate the performance of the HANDOC score to identify patients at high-risk for IE and the Duke clinical criteria of the European Society of Cardiology (ESC; 2015 and 2023 versions) and the 2023 version from the International Society of Cardiovascular Infectious Diseases (ISCVID) in diagnosing IE among patients with streptococcal bacteremia. METHODS: This retrospective study included adult patients with streptococcal bacteremia hospitalized at Lausanne University Hospital. Episodes were classified as IE by the Endocarditis Team. A HANDOC score >2 classified patients as high-risk for IE. RESULTS: Among 851 episodes with streptococcal bacteremia, IE was diagnosed in 171 episodes (20%). Among 607 episodes with non-beta-hemolytic streptococci, 213 (35%) had HANDOC scores >2 points; 132 (22%) had IE. The sensitivity of the HANDOC score to identify episodes at high-risk for IE was 95% (90-98%), the specificity 82% (78-85%), and the NPV 98% (96-99%). 2015 Duke-ESC, 2023 Duke-ISCVID, and 2023 Duke-ESC clinical criteria classified 114 (13%), 145 (17%), and 126 (15%) episodes as definite IE, respectively. Sensitivity for the 2015 Duke-ESC, 2023 Duke-ISCVID, and 2023 Duke-ESC clinical criteria was calculated at 65% (57-72%), 81% (74-86%), and 73% (65-79%), respectively, with specificity at 100% (98-100%), 99% (98-100%), and 99% (98-100%), respectively. CONCLUSIONS: The HANDOC score showed an excellent NPV to identify episodes at high-risk for IE. Among the different versions of the Duke criteria, the 2023 Duke-ISCVID version fared better for the diagnosis of IE among streptococcal bacteremia.

RESUMEN

BACKGROUND: The Duke criteria for infective endocarditis (IE) diagnosis underwent revisions in 2023 by the European Society of Cardiology (ESC) and the International Society for Cardiovascular Infectious Diseases (ISCVID). This study aims to assess the diagnostic accuracy of these criteria, focusing on patients with Staphylococcus aureus bacteremia (SAB). METHODS: This Swiss multicenter study conducted between 2014 and 2023 pooled data from three cohorts. It evaluated the performance of each iteration of the Duke criteria by assessing the degree of concordance between definite S. aureus IE (SAIE) and the diagnoses made by the Endocarditis Team (2018-23) or IE expert clinicians (2014-17). RESULTS: Among 1344 SAB episodes analyzed, 486 (36%) were identified as cases of SAIE. The 2023 Duke-ISCVID and 2023 Duke-ESC criteria demonstrated improved sensitivity for SAIE diagnosis (81% and 82%, respectively) compared to the 2015 Duke-ESC criteria (75%). However, the new criteria exhibited reduced specificity for SAIE (96% for both) compared to the 2015 criteria (99%). Spondylodiscitis was more prevalent among patients with SAIE compared to those with SAB alone (10% vs 7%, P = .026). However, when patients meeting the minor 2015 Duke-ESC vascular criterion were excluded, the incidence of spondylodiscitis was similar between SAIE and SAB patients (6% vs 5%, P = .461). CONCLUSIONS: The 2023 Duke-ISCVID and 2023 Duke-ESC clinical criteria show improved sensitivity for SAIE diagnosis compared to 2015 Duke-ESC criteria. However, this increase in sensitivity comes at the expense of reduced specificity. Future research should aim at evaluating the impact of each component introduced within these criteria.

RESUMEN

In this retrospective/prospective study, we assessed the role of fundoscopy in 711 episodes with suspected infective endocarditis (IE); 238 (33%) had IE. Ocular embolic events (retinal emboli or chorioretinitis/endophthalmitis) and Roth spots were found in 37 (5%) and 34 (5%) episodes, respectively, but had no impact on IE diagnosis.

RESUMEN

BACKGROUND: Since publication of Duke criteria for infective endocarditis (IE) diagnosis, several modifications have been proposed. We aimed to evaluate the diagnostic performance of the Duke-ISCVID (International Society of Cardiovascular Infectious Diseases) 2023 criteria compared to prior versions from 2000 (Duke-Li 2000) and 2015 (Duke-ESC [European Society for Cardiology] 2015). METHODS: This study was conducted at 2 university hospitals between 2014 and 2022 among patients with suspected IE. A case was classified as IE (final IE diagnosis) by the Endocarditis Team. Sensitivity for each version of the Duke criteria was calculated among patients with confirmed IE based on pathological, surgical, and microbiological data. Specificity for each version of the Duke criteria was calculated among patients with suspected IE for whom IE diagnosis was ruled out. RESULTS: In total, 2132 episodes with suspected IE were included, of which 1101 (52%) had final IE diagnosis. Definite IE by pathologic criteria was found in 285 (13%), 285 (13%), and 345 (16%) patients using the Duke-Li 2000, Duke-ESC 2015, or the Duke-ISCVID 2023 criteria, respectively. IE was excluded by histopathology in 25 (1%) patients. The Duke-ISCVID 2023 clinical criteria showed a higher sensitivity (84%) compared to previous versions (70%). However, specificity of the new clinical criteria was lower (60%) compared to previous versions (74%). CONCLUSIONS: The Duke-ISCVID 2023 criteria led to an increase in sensitivity compared to previous versions. Further studies are needed to evaluate items that could increase sensitivity by reducing the number of IE patients misclassified as possible, but without having detrimental effect on specificity of Duke criteria.

RESUMEN

Among 302 episodes with prosthetic valve endocarditis (PVE), one-year mortality was 31%. There was no evidence indicating that early-onset PVE within 6 months from valve surgery led to a worse outcome compared to late-onset PVE (21% versus 32%; p=0.126), despite similar redo valve surgeries across both categories.

RESUMEN

BACKGROUND: Diagnosing infective endocarditis (IE) poses a significant challenge. This study aimed to compare the diagnostic accuracy of the 2015 and 2023 Duke clinical criteria introduced by the European Society of Cardiology (ESC) in a cohort of patients suspected of having IE. METHODS: Conducted retrospectively at two Swiss University Hospitals between 2014-2023, the study involved patients with suspected IE. Each hospitals' Endocarditis Team categorized case as either IE or not IE. The performance of each iteration of the Duke-ESC clinical criteria was assessed based on the agreement between definite IE and the diagnoses made by the Endocarditis Team. RESULTS: Among the 3127 episodes with suspected IE, 1177 (38%) were confirmed to have IE. Using the 2015 Duke-ESC clinical criteria, 707 (23%) episodes were deemed definite IE, with 696 (98%) receiving a final IE diagnosis. With the 2023 Duke-ESC clinical criteria, 855 (27%) episodes were classified as definite IE, of which 813 (95%) were confirmed as IE. The 2015 and 2023 Duke-ESC clinical criteria categorized 1039 (33%) and 1034 (33%) episodes, respectively, as possible IE. Sensitivity for the 2015 Duke-ESC and the 2023 Duke-ESC clinical criteria was calculated at 59% (95% CI: 56-62%), and 69% (66-72%), respectively, with specificity at 99% (99-100%), and 98% (97-98%), respectively. CONCLUSIONS: The 2023 ESC criteria demonstrated significant improvements in sensitivity compared to the 2015 version, although one-third of episodes were classified as possible IE by both versions.

RESUMEN

PURPOSE: Embolic events (EEs) are a common complication of left-side infective endocarditis (IE). The aim of the present study was to identify risk factors for the occurrence of EEs before or after antibiotic treatment instauration among patients with definite or possible IE. METHODS: This retro-prospective study was conducted at the Lausanne University Hospital, Lausanne, Switzerland, from January 2014 to June 2022. EEs and IE were defined according to modified Duke criteria. RESULTS: A total of 441 left-side IE episodes were included (334: 76% were definite and 107; 24% possible IE). EE were diagnosed in 260 (59%) episodes; in 190 (43%) before antibiotic treatment initiation and 148 (34%) after. Central nervous system (184; 42%) was the most common site of EE. Multivariable analysis identified S. aureus (P 0.022), immunological phenomena (P < 0.001), sepsis (P 0.027), vegetation size ≥ 10 mm (P 0.003) and intracardiac abscess (P 0.022) as predictors of EEs before antibiotic treatment initiation. For EEs after antibiotic treatment initiation, multivariable analysis revealed vegetation size ≥ 10 mm (P < 0.001), intracardiac abscess (P 0.035) and prior EE (P 0.042), as independent predictors of EEs, while valve surgery (P < 0.001) was associated with lower risk for EEs. CONCLUSIONS: We reported a high percentage of EEs among patients with left-side IE; vegetation size, intracardiac abscess, S. aureus and sepsis were independently associated with the occurrence of EEs. In addition to antibiotic treatment, early surgery led to further decrease in EEs incidence.

RESUMEN

INTRODUCTION: The use of esophageal temperature monitoring (ETM) for the prevention of esophageal injury during atrial fibrillation (AF) ablation is often advocated. However, evidence supporting its use is scarce and controversial. We therefore aimed to review the evidence assessing the efficacy of ETM for the prevention of esophageal injury. METHODS: We performed a meta-analysis and systematic review of the available literature from inception to December 31, 2022. All studies comparing the use of ETM, versus no ETM, during radiofrequency (RF) AF ablation and which reported the incidence of endoscopically detected esophageal lesions (EDELs) were included. RESULTS: Eleven studies with a total of 1112 patients undergoing RF AF ablation were identified. Of those patients, 627 were assigned to ETM (56%). The overall incidence of EDELs was 9.8%. The use of ETM during AF ablation was associated with a non significant increase in the incidence of EDELs (12.3% with ETM, vs. 6.6 % without ETM, odds ratio, 1.44, 95%CI, 0.49, 4.22, p = .51, I2 = 72%). The use of ETM was associated with a significant increase in the energy delivered specifically on the posterior wall compared to patients without ETM (mean power difference: 5.13 Watts, 95% CI, 1.52, 8.74, p = .005). CONCLUSIONS: The use of ETM does not reduce the incidence of EDELs during RF AF ablation. The higher energy delivered on the posterior wall is likely attributable to a false sense of safety that may explain the lack of benefit of ETM. Further randomized controlled trials are needed to provide conclusive results.

RESUMEN

Amyloidosis is a systemic infiltrative disease characterized by deposition of misfolded proteins in tissues, notably affecting the heart. According to type of protein, various types are known with the most prevalent being light-chain and transthyretin amyloidosis. Prognosis is dismal with progression to severe heart failure without disease-modifying treatment. Latter having dramatically improved over the last decade, prompt diagnosis is of paramount importance. Recognition of early signs followed by multidisciplinary approach is essential for optimal patient management.


L'amyloïdose est une maladie infiltrative systémique caractérisée par le dépôt intratissulaire de protéines. Selon l'origine de la protéine on distingue différents types d'amyloïdose, mais ce sont essentiellement l'amyloïdose à chaînes légères et celle associée à la transthyrétine qui affectent le myocarde. Le pronostic de l'amyloïdose cardiaque est sombre, évoluant vers une insuffisance cardiaque terminale en absence de traitement spécifique. Avec l'arrivée récente de thérapies pouvant ralentir l'évolution de la maladie, un diagnostic précoce est devenu primordial. La reconnaissance des signes précurseurs de la maladie et la mise en place rapide de traitements dans un centre de référence de l'amyloïdose sont essentielles pour une gestion optimale des patients.

RESUMEN

Coronary Computed Tomography Angiography (CCTA) has now become an established tool in the diagnostic process for patients suspected of coronary artery disease. In light of rapid technological development, CCTA has evolved into an imaging modality providing both anatomical and functional information to guide patient management. In this article, we describe the role of cardiac CT in assessing atherosclerotic plaque, chest pain evaluation, cardiovascular risk stratification, planning and guiding coronary intervention, as well as structural heart diseases.


Le scanner coronarien est actuellement un outil reconnu dans le processus diagnostique des patients chez qui on suspecte une maladie coronarienne. Bénéficiant d'un développement technologique rapide et procurant des informations tant morphologiques que fonctionnelles, le CT cardiaque devient une modalité d'imagerie incontournable pour orienter la prise en charge des patients. Dans cet article, nous décrivons le rôle du CT cardiaque dans l'évaluation de la plaque d'athérosclérose, des douleurs thoraciques, de la stratification du risque cardiovasculaire, de la planification et du guidage de l'intervention coronarienne, ainsi que des maladies cardiaques structurelles.

RESUMEN

BACKGROUND: Cerebral embolic events (CEEs) are common complications of infective endocarditis (IE), and their presence can modify diagnosis and therapeutic plans. The aim of the present study was to assess the role of cerebral imaging (Cer-Im) on diagnosis and management of patients with suspected IE. METHODS: This study was conducted at the Lausanne University Hospital, Lausanne, Switzerland, from January 2014 to June 2022. CEEs and IE were defined according to modified Duke criteria of the European Society of Cardiology (ESC) guidelines. RESULTS: Among 573 patients with IE suspicion and Cer-Im, 239 (42%) patients had neurological symptoms. At least 1 CEE was found in 254 (44%) episodes. Based on Cer-Im findings, episodes were reclassified from rejected to possible or from possible to definite IE in 3 (1%) and 25 (4%) patients, respectively (0% and 2% in asymptomatic patients, respectively). Among the 330 patients with possible or definite IE, at least 1 CEE was found in 187 (57%) episodes. A new surgical indication (in association with left-side vegetation >10 mm) was established in 74/330 (22%) IE patients and 30/155 (19%) asymptomatic IE patients, respectively. CONCLUSIONS: Cer-Im in asymptomatic patients with IE suspicion showed limited potential for improving the diagnosis of IE. In contrast, performing Cer-Im in asymptomatic patients with IE may be useful for decision making, because Cer-Im findings led to the establishment of new operative indication for valvular surgery in one fifth of patients according to ESC guidelines.

RESUMEN

Immune checkpoint inhibitors (ICIs) have fundamentally changed the treatment landscape of various cancers. While ICI treatments result in improved survival, quality of life and are cost-effective, the majority of patients experience at least one immune-related adverse event (irAE). Many of these side effects cause little discomfort or are asymptomatic; however, irAEs can affect any organ and are potentially life-threatening. Consequently, early diagnosis and appropriate treatment of irAEs are critical for optimizing long-term outcomes and quality of life in affected patients. Some irAEs are diagnosed according to typical symptoms, others by abnormal findings from diagnostic tests. While there are various guidelines addressing the management of irAEs, recommendations for the early recognition of irAEs as well as the optimal extent and frequency of laboratory tests are mostly lacking. In clinical practice, blood sampling is usually performed before each ICI administration (i.e., every 2-3 weeks), often for several months, representing a burden for patients as well as health care systems. In this report, we propose essential laboratory and functional tests to improve the early detection and management of irAEs and in cancer patients treated with ICIs. These multidisciplinary expert recommendations regarding essential laboratory and functional tests can be used to identify possible irAEs at an early time point, initiate appropriate interventions to improve patient outcomes, and reduce the burden of blood sampling during ICI treatment.

RESUMEN

Background Patients with mitral valve prolapse (MVP) may develop adverse outcomes even in the absence of mitral regurgitation or left ventricular (LV) dysfunction. Purpose To investigate the prognostic value of mitral annulus disjunction (MAD) and myocardial fibrosis at late gadolinium enhancement (LGE) cardiac MRI in patients with MVP without moderate-to-severe mitral regurgitation or LV dysfunction. Materials and Methods In this longitudinal retrospective study, 118 144 cardiac MRI studies were evaluated between October 2007 and June 2020 at 15 European tertiary medical centers. Follow-up was from the date of cardiac MRI examination to June 2020; the minimum and maximum follow-up intervals were 6 months and 156 months, respectively. Patients were excluded if at least one of the following conditions was present: cardiomyopathy, LV ejection fraction less than 40%, ischemic heart disease, congenital heart disease, inflammatory heart disease, moderate or worse mitral regurgitation, participation in competitive sport, or electrocardiogram suggestive of channelopathies. In the remainder, cardiac MRI studies were reanalyzed, and patients were included if they were aged 18 years or older, MVP was diagnosed at cardiac MRI, and clinical information and electrocardiogram monitoring were available within 3 months from cardiac MRI examination. The end point was a composite of adverse outcomes: sustained ventricular tachycardia (VT), sudden cardiac death (SCD), or unexplained syncope. Multivariable Cox regression analysis was performed. Results A total of 474 patients (mean age, 47 years ± 16 [SD]; 244 women) were included. Over a median follow-up of 3.3 years, 18 patients (4%) reached the study end point. LGE presence (hazard ratio, 4.2 [95% CI: 1.5, 11.9]; P = .006) and extent (hazard ratio, 1.2 per 1% increase [95% CI: 1.1, 1.4]; P = .006), but not MAD presence (P = .89), were associated with clinical outcome. LGE presence had incremental prognostic value over MVP severity and sustained VT and aborted SCD at baseline (area under the receiver operating characteristic curve, 0.70 vs 0.62; P = .03). Conclusion In contrast to mitral annulus disjunction, myocardial fibrosis determined according to late gadolinium enhancement at cardiac MRI was associated with adverse outcome in patients with mitral valve prolapse without moderate-to-severe mitral regurgitation or left ventricular dysfunction. © RSNA, 2022 Online supplemental material is available for this article.

RESUMEN

OBJECTIVES: The identification of patients with mitral valve prolapse (MVP) presenting high arrhythmic risk remains challenging. Cardiovascular Magnetic Resonance (CMR) feature tracking (FT) may improve risk stratification. We analyzed the role of CMR-FT parameters in relation to the incidence of complex ventricular arrhythmias (cVA) in patients with MVP and mitral annular disjunction (MAD). METHODS: 42 patients with MVP and MAD who underwent 1.5 T CMR were classified as MAD-cVA (n = 23, 55%) in case of cVA diagnosed on a 24-h Holter monitoring and as MAD-noVA in the absence of cVA (n = 19, 45%). MAD length, late gadolinium enhancement (LGE), basal segments myocardial extracellular volume (ECV) and CMR-FT were assessed. RESULTS: LGE was more frequent in the MAD-cVA group in comparison with the MAD-noVA group (78% vs 42%, p = 0.002) while no difference was observed in terms of basal ECV. Global longitudinal strain (GLS) was reduced in MAD-cVA compared to MAD-noVA (- 18.2% ± 4.6% vs - 25.1% ± 3.1%, p = 0.004) as well as global circumferential strain (GCS) at the mid-ventricular level (- 17.5% ± 4.7% vs - 21.6% ± 3.1%, p = 0.041). Univariate analysis identified as predictors of the incidence of cVA: GCS, circumferential strain (CS) in the basal and mid infero-lateral wall, GLS, regional longitudinal strain (LS) in the basal and mid-ventricular inferolateral wall. Reduced GLS [Odd ratio (OR):1.56 (confidence interval (CI) 95%: 1.45-2.47; p < 0.001)] and regional LS in the basal inferolateral wall [OR: 1.62 (CI 95%: 1.22-2.13; p < 0.001)] remained independent prognostic factors in multivariate analysis. CONCLUSION: In patients with MVP and MAD, CMR-FT parameters are correlated with the incidence of cVA and may be of interest in arrhythmic risk stratification.

RESUMEN

BACKGROUND: A smartphone 12-Lead ECG that enables layman ECG screening is still lacking. We aimed to validate D-Heart ECG device, a smartphone 8/12 Lead electrocardiograph with an image processing algorithm to guide secure electrode placement by non-professional users. METHODS: One-hundred-fourty-five patients with HCM were enrolled. Two uncovered chest images were acquired using the smartphone camera. An image with virtual electrodes placement by imaging processing algorithm software was compared to the 'gold standard' electrode placement by a doctor. D-Heart 8 and 12-Lead ECG were obtained, immediately followed by 12­lead ECGs and were assessed by 2 independent observers. Burden of ECG abnormalities was defined by a score based on the sum of 9 criteria, identifying four classes of increasing severity. RESULTS: A total of 87(60%) patients presented a normal/mildly abnormal ECG, whereas 58(40%) had moderate or severe ECG alteration. Eight(6%) patients had ≥1 misplaced electrode. D-Heart 8-Lead and 12­lead ECGs concordance according to Cohen's weighted kappa test was 0,948 (p < 0,001, agreement of 97.93%). Concordance was high for the Romhilt-Estes score (kw = 0,912; p < 0.01). Concordance between D-Heart 12-Lead ECG and standard 12-Lead ECG was perfect (kw = 1). PR and QRS intervals measurements comparison with Bland-Altman method showed good accuracy (95% limit of agreement ±18 ms for PR and ± 9 ms for QRS). CONCLUSIONS: D-Heart 8/12-Lead ECGs proved accurate, allowing an assessment of ECG abnormalities comparable to the standard 12­lead ECG in patients with HCM. The image processing algorithm provided accurate electrode placement, standardizing exam quality, potentially opening perspectives for layman ECG screening campaigns.

RESUMEN

Cardiovascular magnetic resonance (CMR) is an imaging modality with growing indications in cardiology. The purpose of this article is to illustrate the current clinical applications of CMR across the spectrum of ischemic heart disease, non-ischemic cardiomyopathies, cardiac arrhythmias and valvular or vascular heart disease. The strengths of CMR lie in its ability to comprehensively image, without the need for ionizing radiation, cardiac and vascular anatomy, function, perfusion, viability and physiology, providing a powerful non-invasive tool for patient diagnosis and prognostication.


La résonance magnétique cardiovasculaire (RMC) est une modalité d'imagerie avec des applications croissantes en cardiologie. Le but de cet article est d'illustrer les applications cliniques actuelles de la RMC dans la cardiopathie ischémique, dans le domaine des cardiomyopathies, les troubles du rythme cardiaque et les maladies valvulaires ou vasculaires. Ses points forts résident dans sa capacité à imager de manière complète, sans besoin de rayonnement ionisant, l'anatomie, la fonction, la perfusion, la viabilité et la physiologie cardiaques et vasculaires, offrant un puissant outil non invasif pour le diagnostic et le pronostic des patients.

RESUMEN

The year of 2022 was marked by many novelties in the fields of interventional cardiology, heart failure, electrophysiology, cardiac imaging, and congenital heart disease. These advances will certainly change our daily practice, on top of improving the diagnosis and treatment of many heart conditions. In addition, the European Society of Cardiology has updated its guidelines on pulmonary hypertension, ventricular arrhythmias and sudden death, cardiovascular assessment of patients undergoing non-cardiac surgery. The members of the Cardiology division of Lausanne University Hospital (CHUV) here present the publications which they considered to be the most important of the past year.


L'année 2022 a été marquée par de nombreuses nouveautés dans les domaines de la cardiologie interventionnelle, de l'insuffisance cardiaque, de l'électrophysiologie, de l'imagerie cardiaque et des cardiopathies congénitales. Ces progrès vont certainement faire évoluer notre pratique quotidienne, en plus d'améliorer le diagnostic et le traitement de nombreuses cardiopathies. Par ailleurs, la Société européenne de cardiologie a mis à jour ses recommandations portant sur l'hypertension pulmonaire, les arythmies ventriculaires et la mort subite ainsi que le bilan cardiologique avant une chirurgie non cardiaque. Les membres du Service de cardiologie du CHUV vous présentent ici les travaux qui leur ont semblé être les plus importants de l'année écoulée.

RESUMEN

BACKGROUND: The use of stress perfusion-cardiovascular magnetic resonance (CMR) imaging remains limited in patients with implantable devices. The primary goal of the study was to assess the safety, image quality, and the diagnostic value of stress perfusion-CMR in patients with MR-conditional transvenous permanent pacemakers (PPM) or implantable cardioverter-defibrillators (ICD). METHODS: Consecutive patients with a transvenous PPM or ICD referred for adenosine stress-CMR were enrolled in this single-center longitudinal study. The CMR protocol was performed using a 1.5 T system according to current guidelines while all devices were put in MR-mode. Quality of cine, late-gadolinium-enhancement (LGE), and stress perfusion sequences were assessed. An ischemia burden of ≥ 1.5 segments was considered significant. We assessed the safety, image quality and the occurrence of interference of the magnetic field with the implantable device. In case of ischemia, we also assessed the correlation with the presence of significant coronary lesions on coronary angiography. RESULTS: Among 3743 perfusion-CMR examinations, 66 patients had implantable devices (1.7%). Image quality proved diagnostic in 98% of cases. No device damage or malfunction was reported immediately and at 1 year. Fifty patients were continuously paced during CMR. Heart rate and systolic blood pressure remained unchanged during adenosine stress, while diastolic blood pressure decreased (p = 0.007). Six patients (9%) had an ischemia-positive stress CMR and significant coronary stenoses were confirmed by coronary angiography in all cases. CONCLUSION: Stress perfusion-CMR is safe, allows reliable ischemia detection, and provides good diagnostic value.
