Wideband black-blood late gadolinium enhancement imaging for improved myocardial scar assessment in patients with cardiac implantable electronic devices.

PURPOSE: Wideband phase-sensitive inversion recovery (PSIR) late gadolinium enhancement (LGE) enables myocardial scar imaging in implantable cardioverter defibrillators (ICD) patients, mitigating hyperintensity artifacts. To address subendocardial scar visibility challenges, a 2D breath-hold single-shot electrocardiography-triggered black-blood (BB) LGE sequence was integrated with wideband imaging, enhancing scar-blood contrast. METHODS: Wideband BB, with increased bandwidth in the inversion pulse (0.8-3.8 kHz) and T2 preparation refocusing pulses (1.6-5.0 kHz), was compared with conventional and wideband PSIR, and conventional BB, in a phantom and sheep with and without ICD, and in six patients with cardiac devices and known myocardial injury. ICD artifact extent was quantified in the phantom and specific absorption rate (SAR) was reported for each sequence. Image contrast ratios were analyzed in both phantom and animal experiments. Expert radiologists assessed image quality, artifact severity, and scar segments in patients and sheep. Additionally, histology was performed on the sheep's heart. RESULTS: In the phantom, wideband BB reduced ICD artifacts by 62% compared to conventional BB while substantially improving scar-blood contrast, but with a SAR more than 24 times that of wideband PSIR. Similarly, the animal study demonstrated a considerable increase in scar-blood contrast with wideband BB, with superior scar detection compared with wideband PSIR, the latter confirmed by histology. In alignment with the animal study, wideband BB successfully eliminated severe ICD hyperintensity artifacts in all patients, surpassing wideband PSIR in image quality and scar detection. CONCLUSION: Wideband BB may play a crucial role in imaging ICD patients, offering images with reduced ICD artifacts and enhanced scar detection.

Prevention of esophageal lesions during atrial fibrillation catheter ablation using esophageal temperature monitoring: A systematic review and meta-analysis.

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.

Cardiac magnetic resonance biomarkers as surrogate endpoints in cardiovascular trials for myocardial diseases.

Cardiac magnetic resonance offers multiple facets in the diagnosis, risk stratification, and management of patients with myocardial diseases. Particularly, its feature to precisely monitor disease activity lends itself to quantify response to novel therapeutics. This review critically appraises the value of cardiac magnetic resonance imaging biomarkers as surrogate endpoints for prospective clinical trials. The primary focus is to comprehensively outline the value of established cardiac magnetic resonance parameters in myocardial diseases. These include heart failure, cardiac amyloidosis, iron overload cardiomyopathy, hypertrophic cardiomyopathy, cardio-oncology, and inflammatory cardiomyopathies like myocarditis and sarcoidosis.

[Cardiac CT in 2024]. / CT cardiaque en 2024.

[Cardiovascular magnetic resonance in clinical practice: who, when and why?] / Résonance magnétique cardiovasculaire en pratique clinique : pour qui, quand et pourquoi ?

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.

[An update on some atypical electrocardiographic forms of acute coronary syndrome The "STEMI equivalents"]. / Mise au point sur certaines formes électrocardiographiques atypiques du syndrome coronarien aigu - « Équivalents STEMI ¼.

The diagnosis of acute coronary syndrome with ST segment elevation (STEMI) is based on clinical symptoms suggestive of acute myocardial ischemia and precise ECG criteria. STEMI is due to an acute occlusion or subocclusion of a coronary artery, generating a transmural ischaemia, requiring coronary angiography with urgent coronary revascularization. However, some authors consider the current STEMI ECG criteria to be too restrictive: up to 30 % of patients who do not meet these criteria present with critical coronary artery stenosis or acute coronary occlusion. Atypical electrocardiographic patterns, known as "STEMI equivalents", can be found in some cases and justify a rapid cardiological evaluation. We present a pragmatic review of five STEMI equivalents.

Le diagnostic de syndrome coronarien aigu avec sus-décalage du segment ST (ST-Elevation Myocardial Infarction (STEMI)) est basé sur une clinique évocatrice d'une ischémie myocardique et des critères ECG précis. Le STEMI est le reflet d'une (sub)occlusion aiguë d'une artère coronaire engendrant une ischémie transmurale, nécessitant une coronarographie avec un geste de revascularisation en urgence. Certains auteurs considèrent les critères ECG actuels du STEMI comme étant trop restrictifs : jusqu'à 30 % des patients ne remplissant pas ces critères présenteraient une sténose coronarienne critique ou une occlusion coronarienne aiguë. Des aspects électrocardiographiques atypiques, dits « équivalents STEMI ¼, peuvent être mis en évidence dans certains cas et justifient une prise en charge cardiologique rapide. Nous présentons une revue pragmatique de cinq équivalents STEMI.

Impact of manual thrombectomy on microvascular obstruction in STEMI patients.

OBJECTIVE: To assess the effect of manual thrombectomy (MT) on microvascular obstruction (MVO) using cardiac magnetic resonance (CMR) in ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI). METHODS AND RESULTS: Three hundred and eighty-three patients admitted for STEMI and undergoing CMR fulfilled the inclusion criteria and were categorized into two groups (did or did not undergo MT). The two primary endpoints were the occurrence and extent of MVO, analyzed as a categorical variable and as a semicontinuous variable. Among the 383 patients, 49.1% exhibited MVO. Both the incidence of MVO and the median number of segments presenting with MVO were significantly higher in the MT group than in the no-MT group, (59.5 vs. 38.9%, p < .001) and (1.5 [0;4] vs. 0 [0;2], p < .001). Analysis stratified on coronary thrombus grade showed similar results, only in patients with a high thrombus burden (60.7 vs. 43.5%, p = .004, and 2 [0;4] vs. 0 [0;3], p = .001. When adjusting for baseline differences, MT remained a determinant of MVO occurrence and extent (odds ratio, OR 1.802 [95% confidence interval, CI 1.080-3.009], p = .024) and ß = .137, p = .024) in patients with a high thrombus grade. CONCLUSION: In STEMI patients, MT was associated with the occurrence and extent of MVO, on CMR, especially in patients with a high thrombus burden.

Interatrial septum dissection and atrial wall hematoma following transseptal puncture: A systematic review of the literature.

BACKGROUND: Interatrial septum (IAS) dissection due to transseptal puncture (TSP) is a rare, underreported complication of the procedure. Data on the mechanism, diagnosis, and management of this complication are lacking. METHODS: We conducted a systematic review of all reported cases of IAS dissection with or without associated LA hematoma due to TSP, by thoroughly searching MEDLINE and EMBASE through May 2019. RESULTS: After screening of n = 882 studies, eight studies with a total of 19 patients addressed the complication of IAS dissection and/or LA hematoma secondary to TSP. Median age was 63 years with a 1:1 male to female ratio. Ablation of atrial fibrillation was the most frequently reported procedure (84%). Diagnosis was established using fluoroscopy with contrast injection (58%), TEE (32%) or intracardiac echocardiography (5%). The mechanism identified involved puncture of the septum secundum portion of the IAS, leading to transient needle passage into the extracardiac space. In the majority of patients, the hematoma remained localized in the IAS and management was conservative with progressive resolution of the hematoma during follow-up (95%). Two patients (11%) required further intervention by either pericardiocentesis or surgical drainage due to hemodynamic instability. CONCLUSIONS: IAS dissection with or without hematoma after TSP remains an underdiagnosed entity. The main mechanism involves lesion to the septum secundum portion of the IAS, resulting in needle passage into the extracardiac space and local bleeding. Although conservative management may be sufficient in the majority of cases, interventional cardiologists should be familiar with this complication and its diagnosis.

[The year in cardiology : 2018]. / Cardiologie.

This review article provides a broad overview of the novelties in cardiology in 2018.

Impact of CD14 Polymorphisms on Anti-Apolipoprotein A-1 IgG-Related Coronary Artery Disease Prediction in the General Population.

OBJECTIVE: We aimed to determine whether autoantibodies against apoA-1 (apolipoprotein A-1; anti-apoA-1 IgG) predict incident coronary artery disease (CAD), defined as adjudicated incident myocardial infarction, angina, percutaneous coronary revascularization, or bypass grafting, in the general population. We further investigated whether this association is modulated by a functional CD14 receptor single nucleotide polymorphism. APPROACH AND RESULTS: In a prospectively studied, population-based cohort of 5220 subjects (mean age 52.6±10.7 years, 47.4% males), followed over a median period of 5.6 years, subjects positive versus negative for anti-apoA-1 IgG presented a total CAD rate of 3.9% versus 2.8% (P=0.077) and a nonfatal CAD rate of 3.6% versus 2.3% (P=0.018), respectively. After multivariate adjustment for established cardiovascular risk factors, the hazard ratios of anti-apoA-1 IgG for total and nonfatal CAD were: hazard ratio=1.36 (95% confidence interval, 0.94-1.97; P=0.105) and hazard ratio=1.53 (95% confidence interval, 1.03-2.26; P=0.034), respectively. In subjects with available genetic data for the C260T rs2569190 single nucleotide polymorphism in the CD14 receptor gene (n=4247), we observed a significant interaction between anti-apoA-1 IgG and rs2569190 allele status with regards to CAD risk, with anti-apoA-1 IgG conferring the highest risk for total and nonfatal CAD in non-TT carriers, whereas being associated with the lowest risk for total and nonfatal CAD in TT homozygotes (P for interaction =0.011 and P for interaction =0.033, respectively). CONCLUSIONS: Anti-apoA-1 IgG are independent predictors of nonfatal incident CAD in the general population. The strength of this association is dependent on a functional polymorphism of the CD14 receptor gene, a finding suggesting a gene-autoantibody interaction for the development of CAD.

[TAVI in 2018 : new indications and open questions]. / TAVI en 2018 : nouvelles indications et questions ouvertes.

The last years, various large randomized studies have demonstrated the benefit of TAVI (transcatheter aortic valve implantation) over medical therapy or over conventional surgical treatment in inoperable or very high risk patients with symptomatic severe aortic stenosis. More recently, new data has also shown that among patients at intermediate risk, TAVI is at least as beneficial as surgical valve replacement. In this article, we will focus on the new recommendations of the European society of cardiology but also on issues that remain open.

Ces dernières années, différentes grandes études randomisées ont démontré le bénéfice du TAVI (transcatheter aortic valve implantation) par rapport au traitement médicamenteux ou au traitement chirurgical conventionnel chez les patients avec sténose aortique sévère symptomatique inopérables ou à très haut risque. Plus récemment, de nouvelles données ont également démontré que parmi les patients à risque intermédiaire, le TAVI est au moins aussi bénéfique que le remplacement valvulaire chirurgical. Dans le présent article, nous allons nous intéresser aux nouvelles recommandations de la Société européenne de cardiologie mais également aux questions qui demeurent ouvertes.

[Approach to chronic mitral regurgitation in 2016]. / L' insuffisance mitrale: mise au point en 2016.

Mitral regurgitation (MR) is the most frequent valvular disease in industrialised countries. MR is classified as primary (mostly degenerative with valve prolapse) or secondary (mainly due to underlying ischemic heart disease resulting in deformation of the valve structure). Surgical repair represents the optimal treatment for severe primary MR, whereas the benefits of surgical correction of secondary MR are controversial. Over the past few years, transcatheter techniques have been developed to treat MR, such as the percutaneous edge-to-edge procedure (MitraClip). These approaches represent a novel therapeutic choice for patients judged inoperable by the "heart team". This review article aims to summarize the principles of MR assessment and discuss current therapeutic options for severe MR, taking into account the latest advances in the field.

Cardiac Magnetic Resonance Evaluation of LV Remodeling Post-Myocardial Infarction: Prognosis, Monitoring and Trial Endpoints.

Adverse left ventricular remodeling (ALVR) and subsequent heart failure after myocardial infarction (MI) remain a major cause of patient morbidity and mortality worldwide. Overt inflammation has been identified as the common pathway underlying myocardial fibrosis and development of ALVR post-MI. With its ability to simultaneously provide information about cardiac structure, function, perfusion, and tissue characteristics, cardiac magnetic resonance (CMR) is well poised to inform prognosis and guide early surveillance and therapeutics in high-risk cohorts. Further, established and evolving CMR-derived biomarkers may serve as clinical endpoints in prospective trials evaluating the efficacy of novel anti-inflammatory and antifibrotic therapies. This review provides an overview of post-MI ALVR and illustrates how CMR may help clinical adoption of novel therapies via mechanistic or prognostic imaging markers.

Transcarotid vascular access for transcatheter aortic valve implantation: is choosing the left side always right?

BACKGROUND: The transcarotid (TC) vascular access for transcatheter aortic valve implantation (TAVI) has emerged as the first-choice alternative to the transfemoral access, in patients unsuitable for the latter. The use of both the left and right common carotid arteries (CCAs) for TC-TAVI has been described, but the optimal side is subject to debate. We conducted this pilot study to compare the level of vessel tortuosity and plaque burden from either the left CCA to the aortic annulus, or the right CCA to the aortic annulus, considering them as surrogates for technical and procedural complexity. METHODS: Consecutive patients who underwent TC-TAVI between 2018 and 2021 in our institution were included. Using three-dimensional reconstruction, pre-TAVI neck and chest computed tomography angiography exams were reviewed to assess the tortuosity index (TI), sum of angles metric, as well as plaque burden, between each CCA and the aortic annulus. RESULTS: We included 46 patients who underwent TC-TAVI. No significant difference regarding the mean TIs between the left and right sides (respectively 1.20 and 1.19, p = 0.82), the mean sum of angles (left side: 396°, right side: 384°, p = 0.27), and arterial plaque burden (arterial plaque found in 30% of left CCAs and 45% of right CCAs, p = 0.19) was found. CONCLUSIONS: We found no convincing data favoring the use of one particular access side over the other one. The choice of the CCA side in TC-TAVI should to be made on a case-by-case basis, in a multidisciplinary fashion, and may also depend on the operators' experience.

Energy Loss Index and Dimensionless Index Outperform Direct Valve Planimetry in Low-Gradient Aortic Stenosis.

Background/Objectives: Among patients with suspected severe aortic stenosis (AS), discordance between effective orifice area (EOA) and transvalvular gradients is frequent and requires a multiparametric workup including flow assessment and calcium-scoring to confirm true severe AS. The aim of this study was to assess direct planimetry, energy loss index (Eli) and dimensionless index (DI) as stand-alone parameters to identify non-severe AS in discordant cases. Methods: In this prospective cohort study, we included consecutive AS patients > 70 years with EOA < 1.0 cm2 referred for valve replacement between 2014 and 2017. AS severity was retrospectively reassessed using the multiparametric work-up recommended in the 2021 ESC/EACTS guidelines. DI and ELi were calculated, and valve area was measured by direct planimetry on transesophageal echocardiography. Results: A total of 101 patients (mean age 82 y; 57% male) were included. Discordance between EOA and gradients was observed in 46% and non-severe AS found in 24% despite an EOA < 1 cm2. Valve planimetry performed poorly, with an area under the ROC curve (AUC) of 0.64. At a cut-off value of >0.82 cm2, sensitivity and specificity to identify non-severe AS were 67 and 66%, respectively. DI and ELi showed a higher diagnostic accuracy, with an AUC of 0.77 and 0.76, respectively. Cut-off values of >0.24 and >0.6 cm2/m2 identified non-severe AS, with a high specificity of 79% and 91%, respectively. Conclusions: Almost one in four patients with EOA < 1 cm2 had non-severe AS according to guideline-recommended multiparametric assessment. Direct valve planimetry revealed poor diagnostic accuracy and should be interpreted with caution. Usual prognostic cut-off values for DI > 0.24 and ELI > 0.6 cm2/m2 identified non-severe AS with high specificity and should therefore be included in the assessment of low-gradient AS.

Head-to-Head Comparison and Temporal Trends of Cardiac MRI Recommendations in ESC versus ACC/AHA Guidelines: A Systematic Review and Meta-Analysis.

Purpose To provide a comprehensive head-to-head comparison and temporal analysis of cardiac MRI indications between the European Society of Cardiology (ESC) and American College of Cardiology/American Heart Association (ACC/AHA) guidelines to identify areas of consensus and divergence. Materials and Methods A systematic review and meta-analysis was conducted. ESC and ACC/AHA guidelines published until May 2023 were systematically screened for recommendations related to cardiac MRI. The class of recommendation (COR) and level of evidence (LOE) for cardiac MRI recommendations were compared between the two guidelines and between newer versus older versions of each guideline using χ2 or Fisher exact tests. Results ESC guidelines included 109 recommendations regarding cardiac MRI, and ACC/AHA guidelines included 90 recommendations. The proportion of COR I and LOE B was higher in ACC/AHA versus ESC guidelines (60% [54 of 90] vs 46.8% [51 of 109]; P = .06 and 53% [48 of 90] vs 35.8% [39 of 109], respectively; P = .01). The increase in the number of cardiac MRI recommendations over time was significantly higher in ESC guidelines (from 63 to 109 for ESC vs from 65 to 90 for ACC/AHA; P = .03). The main areas of consensus were found in heart failure and hypertrophic cardiomyopathy, while the main divergences were in valvular heart disease, arrhythmias, and aortic disease. Conclusion ESC guidelines included more recommendations related to cardiac MRI use, whereas the ACC/AHA recommendations had higher COR and LOE. The number of cardiac MRI recommendations increased significantly over time in both guidelines, indicating the increasing role of cardiac MRI evaluation and management of cardiovascular disease.

Recurrence of an undifferentiated pleomorphic pulmonary artery sarcoma 8 years after initial presentation: a case report.

Background: Primary cardiac tumors remain exceptionally rare, characterized by a poor prognosis. Among them, sarcomas originating in the pulmonary arteries constitute the most infrequent subgroup within primary cardiac sarcomas. Case summary: This report presents the case of a 76-year-old female experiencing a recurrence of an undifferentiated pleomorphic intracardiac pulmonary artery sarcoma located in the right ventricular outflow tract, manifesting 8 years after initial remission. Successful outcomes were attained through a combination of surgical resection, state-of-the-art radiotherapy, and chemotherapy. This comprehensive approach proved essential for optimizing both survival and quality of life. Discussion: The unexpectedly prolonged recurrence-free survival observed in this case underscores the effectiveness of the comprehensive multimodal treatment approach outlined in the existing literature. This highlights the pivotal role of a multidisciplinary strategy in addressing primary cardiac sarcomas, particularly those arising in the pulmonary arteries.
