Abstract
INTRODUCTION AND OBJECTIVES Diffuse homogeneous hypoechoic leaflet thickening, with a wavy leaflet motion documented by transesophageal echocardiography (TEE), has been described in some cases of prosthetic valve endocarditis (PVE) involving aortic bioprosthesis (AoBio-PVE). This echocardiographic finding has been termed valvulitis. We aimed to estimate the prevalence of valvulitis, precisely describe its echocardiographic characteristics, and determine their clinical significance in patients with AoBio-PVE. METHODS From 2011 to 2022, 388 consecutive patients with infective endocarditis (IE) admitted to a tertiary care hospital were prospectively included in a multipurpose database. For this study, all patients with AoBio-PVE (n=86) were selected, and their TEE images were thoroughly evaluated by 3 independent cardiologists to identify all cases of valvulitis. RESULTS The prevalence of isolated valvulitis was 12.8%, and 20.9% of patients had valvulitis accompanied by other classic echocardiographic findings of IE. A total of 9 out of 11 patients with isolated valvulitis had significant valve stenosis, whereas significant aortic valve regurgitation was documented in only 1 patient. Compared with the other patients with AoBio-PVE, cardiac surgery was less frequently performed in patients with isolated valvulitis (27.3% vs 62.7%, P=.017). In 4 out of 5 patients with valve stenosis who did not undergo surgery but underwent follow-up TEE, valve gradients significantly improved with appropriate antibiotic therapy. CONCLUSIONS Valvulitis can be the only echocardiographic finding in infected AoBio and needs to be identified by imaging specialists for early diagnosis. However, this entity is a diagnostic challenge and additional imaging techniques might be required to confirm the diagnosis. Larger series are needed.

Abstract
Abstract
Background
Transcatheter aortic valve replacement (TAVR) is nowadays a safe and increasingly frequent option to treat severe aortic stenosis (AS). Cardiac damage staging has been proposed and validated in some studies as a prognostic tool; however, many patients continue to undergo aortic valve replacement only after there is evidence of cardiac damage. The aim of this study is to assess the potential incremental value of global longitudinal strain (GLS) and right ventricular-arterial coupling (RV-VAc) in the prognostic performance of the cardiac damage staging.
Methods
Consecutive patients with AS and undergoing TAVR were included in our hospital registry. Baseline echocardiography was performed before TAVR according to current guidelines. For this study, patients were classified based on the following stage of cardiac damage: Stage 0: no cardiac damage; Stage 1: left ventricular (LV) damage (LV ejection fraction (LVEF) <50%, LV mass index >95 g/m2 for women, >115 g/m2 for men); Stage 2: left atrial (LA) or mitral valve damage (LA volume index >34 ml/m2, mitral regurgitation moderate-severe, or presence of atrial fibrillation); Stage 3: pulmonary vasculature or tricuspid valve damage (systolic pulmonary artery pressure 60 mmHg, or tricuspid regurgitation moderate-severe); Stage 4: RV damage (TAPSE <1.7 cm, S' <9.5 cm/s).
Results
496 patients were studied. Mean age of the cohort was 81.9±6.2 years, mean aortic valve area was 0.86±0.6 cm2, mean LVEF was 57.9±12.3%, mean LV-GLS was −15.6±3.5% and RV-Vac was 0.61±0.34. Table 1 shows clinical and echo characteristics of patients. Only one patient (0.2%) met criteria for stage 0; 38 (7.7%) patients were in stage 1; 159 (32.1%) patients in stage 2, 157 (31.7%) patients in stage 3 and 141 (28.4%) patients in stage 4. 1-year mortality for stage 1 was (10.5%), for stage 2 (13.7%), for stage 3 (32.2%) and for stage 4 (19.5%). The area under the ROC curve (AUC) for 1-year mortality for the cardiac damage staging system was 0.622, CI (0.539–0.705); the best cut-off value for LV-GLS to predict 1-year mortality was −14% with an AUC of 0.634 CI (0.487–0.781) and RV-VAc had an AUC of 0.748 CI (0.638–858). Finally, the model that included the staging system, LV-GLS and RV-VAc had an AUC ROC of 0.875, CI (0.780–0.971) (Figure 1).
Conclusions
Cardiac damage staging is a good prognostic tool and it has been validated in several studies, however, the addition of feasible and widely available echo parameters such as LV-GLS and RV-VAc can significantly increase its prognostic yield.

Abstract
BACKGROUND Risk stratification for transcatheter edge-to-edge mitral valve repair (TEER) is paramount in the decision-making process for treating severe mitral regurgitation (MR). OBJECTIVES This study sought to create and validate a user-friendly score (MitraScore) to predict the risk of mortality in patients undergoing TEER. METHODS The derivation cohort was based on a multicentric international registry that included 1,119 patients referred for TEER between 2012 and 2020. Score discrimination was assessed using Harrell's c-statistic, and the calibration was evaluated with the Gronnesby and Borgan goodness-of-fit test. An external validation was carried out in 725 patients from the GIOTTO registry. RESULTS After multivariate analysis, we identified 8 independent predictors of mortality during the follow-up (2.1 ± 1.8 years): age ≥75 years, anemia, glomerular filtrate rate <60 mL/min/1.73 m2, left ventricular ejection fraction <40%, peripheral artery disease, chronic obstructive pulmonary disease, high diuretic dose, and no therapy with renin-angiotensin system inhibitors. The MitraScore was derived by assigning 1 point to each independent predictor. The c-statistic was 0.70. Per each point of the MitraScore, the relative risk of mortality increased by 55% (HR: 1.55; 95% CI: 1.44-1.67; P < 0.001). The discrimination and calibration for mortality prediction was better than those of EuroSCORE II (c-statistic 0.61) or Society of Thoracic Surgeons score (c-statistic 0.57). The MitraScore maintained adequate performance in the validation cohort (c-statistic 0.66). The score was also predictive for heart failure rehospitalization and was correlated with the probability of clinical improvement. CONCLUSIONS The MitraScore is a simple prediction algorithm for the prediction of follow-up mortality in patients treated with TEER.

Pre-dilation and Post-dilation in Transcatheter Aortic Valve Replacement: Indications, Benefits and Risks. Interv Cardiol 2021; 16:e28.

Abstract
Transcatheter aortic valve replacement (TAVR) is an established treatment for patients with symptomatic severe aortic stenosis. In recent years, an emphasis has been placed on simplification of the procedure. Balloon predilation was initially considered a mandatory step to cross and prepare the stenotic aortic valve, but several studies demonstrated the feasibility of performing TAVR without balloon valvuloplasty. Balloon postdilation of the implanted valve is sometimes required to optimise results, although many patients do not require this step. Contemporary consensus advocates an individualised approach to TAVR procedures and so balloon pre- and post-dilation are performed selectively. This review aims to outline the advantages and disadvantages of balloon pre- and post-dilation and to identify the scenarios in which they are required during TAVR procedures.

Abstract
Introduction
Prosthesis under-expansion has been associated with higher rates of complications and worse long term outcome after transcatheter aortic valve replacement (TAVR). The objective of the current study was to assess the value of a new “Discongruence index”, to predict the percentage of prosthesis size loss (compared to its nominal size). The “discongruence index” is obtained from the relation between transcatheter valve size and the patient body surface area.
Methods
A total of 247 consecutive patients with severe aortic stenosis that underwent TAVR with balloon expandable Edwards-Sapiens prosthesis or CoreValve Revalving system at our institution were included. The “Discongruence index” was calculated pre-procedurally as the ratio: selected transcatheter valve size (mm) / body surface area (cm2). Two-dimensional transesophageal echocardiography images were studied in the 120–135° plane after the prosthesis deployment, and the maximum anteroposterior diameter was measured (in millimeters). From this measurement was obtained the percentage of prosthesis size loss (compared to the prosthesis nominal size).
Results
Mean age was 82±6 years and 102 patients (41.3%) were men. Mean aortic valvular area before TAVR was 0,87±3,8 cm2, (indexed 0,36±0,1 cm2) and the mean aortic gradient 49,1±16,9 mmHg. Mean prosthesis maximum deployment was 18,9±2,7 mm; absolute loss of prosthesis size compared to nominal 6,5±2,8 mm and the percentage loss of prosthesis size 25.1±9,5%. The “Discongruence index” was predictor of the percentage of prosthesis size loss (y = 5,7650 + 1,3010x, p<0,001), see figure.
Conclusions
The “Discongruence index” is a useful tool to predict the percentage of prosthesis size loss after TAVR. This new index should be taken into consideration in the selection of transcatheter valve sizes to avoid prosthesis under-expansion.

Abstract
INTRODUCTION Significant mitral regurgitation (MR) frequently coexists in patients with severe symptomatic aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). These patients have worse clinical outcomes than those with non-significant MR, especially if MR persists after treatment of the aortic stenosis. The optimal treatment approach for this challenging high-risk population is not well defined. AREAS COVERED This review aims to present the current literature on concomitant significant MR in the TAVR population, and to provide a comprehensive algorithmic approach for clinical decision-making in this challenging cohort of patients. EXPERT OPINION Concomitant mitral and aortic valve disease is a complex clinical entity. An exhaustive and comprehensive assessment of patient's clinical characteristics and mitral valve anatomy and function is required in order to assess the surgical risk, predict the MR response after AVR and evaluate the feasibility of percutaneous MV treatment if necessary. Further developments in transcatheter techniques will expand the indications for double valve treatment in operable and inoperable patients with concomitant significant MR and aortic stenosis.

Abstract
OBJECTIVE The heart team (HT) approach plays a key role in selecting the optimal treatment strategy for patients with aortic stenosis (AS). However, little is known about the HT decision process and its impact on outcomes. The aim of this study was to identify the factors associated with the HT decision and evaluate clinical outcomes according to the treatment choice. METHODS The study included a total of 286 consecutive patients with AS referred for discussion in the weekly HT meeting in a cardiovascular institute over 2 years. Patients were stratified according to the selected therapeutic approach: medical treatment (MT), surgical (SAVR), or transcatheter (TAVR) aortic valve replacement. Baseline characteristics involved in making a therapeutic choice were identified and a decision-making tree was built using classification and regression tree methodology. RESULTS Based on HT discussion, 53 patients were assigned to SAVR, 210 to TAVR, and 23 to MT. Older patients (≥88 years old) were mainly assigned to TAVR or MT according to the logistic EuroSCORE (<or≥28, respectively). While among younger patients (<88 years), significant mitral regurgitation (≥grade III), frailty, Society of Thoracic Surgeons score, and estimated glomerular filtration rate were the most relevant factors influencing treatment allocation. One-year all-cause mortality was 16.6% in the invasive groups (TAVR = 17.2%, SAVR = 14.0%) and 68.7% in the MT arm. CONCLUSION The HT decision was determined by well-recognized risk factors that were used to define a treatment decision algorithm. Future studies with younger and lower-risk patients may identify new contributory factors that may alter the selection process and treatment choice.

Abstract
Background Current consensus recommends extended vascular investigation in patients with spontaneous coronary artery dissection (SCAD). We here report our experience with the use of magnetic resonance angiography (MRA) for screening extra-coronary arteriopathy in patients presenting with SCAD. Methods Patients presenting with SCAD in a Spanish centre underwent prospective contrast-enhanced MRA to assess the cephalic and abdominopelvic arterial territories. Fibromuscular dysplasia (FMD) was diagnosed following European consensus criteria. Other vascular abnormalities were recorded separately. Two vascular radiologists supervised the acquisitions and independently analysed the results for all cases. Results Forty patients with SCAD [mean age 50.9±8.6 years, 90% (n=36) women] were included in the study, 12 patients declined to participate and 5 were excluded (metallic implanted devices). All enrolled patients underwent the screening protocol without complications. MRA demonstrated at least one extra-coronary vascular abnormality in 16 patients (40%): 5 (12.5%) were diagnosed with FMD, 6 (15%) showed arterial tortuosity, 3 (7.5%) had non-FMD focal stenoses, and 2 (5%) were found to have small aneurysms at the celiac trunk and splenic artery. No intracranial aneurysms were detected. At a mean follow-up of 4±3 years from the index episode, two cases experienced SCAD recurrences, one in a patient with FMD and the other one in a patient with arterial tortuosity. No deaths or strokes occurred. Conclusions Systematic extended vascular study with MRA was feasible and demonstrated associated extra-coronary arteriopathy in a substantial proportion of patients presenting with SCAD; however, none required additional intervention or led to vascular events. MRA, being a radiation-free modality, may be the preferred method for screening extracoronary arteriopathy in SCAD, a condition primarily affecting young and middle-age women sensitive to the risks of radiation.

Abstract
PURPOSE Vegetation size is a prognostic predictor in infective endocarditis (IE) and guides surgical management. The aim of this study was to evaluate the accuracy of real-time 3-dimensional transesophageal echocardiography (RT3DTEE) compared to 2DTEE in the diagnosis and characterization of vegetation, as well as its potential clinical impact. METHODS Two hundred and three consecutive patients with IE were recruited (2009-2016) and retrospectively analyzed. Vegetation diameters and area from 68 patients were measured by 2DTEE and RT3DTEE at admission. The association between size and systemic embolisms was evaluated with logistic regression models. Differences in the discriminative power for the best dimensions' cutoff points were assessed by comparing the area under the ROC curves (AUC). RESULTS Vegetation size and area were larger by RT3DTEE (P < 0.001) than by 2DTEE, and RT3DTEE was especially relevant in the characterization of nonfiliform vegetation, Morphology was strongly associated with friability, being sessile vegetation less likely to embolize, compared to filiform and raceme-shaped ones (15.4% vs 46% vs 50%). Major diameter by RT3DTEE had better embolic predictive performance than 2DTEE (AUC 0.76 [0.57-0.89] vs 0.71 [0.53-0.86]; P = 0.611). The best cutoff points associated with embolic events during the infection were 17 mm for RT3DTEE and 15 mm for 2DTEE. Based exclusively on vegetation size, the proportion of patients meeting a surgical indication according to current guidelines is higher using RT3DTEE. CONCLUSIONS RT3DTEE allows a better characterization of IE vegetation than 2DTEE, what may have a clinical impact on surgical management and also prognostic due to a more accurate prediction of embolic risk.

Abstract
BACKGROUND Prosthesis-patient mismatch (PPM) after transcatheter aortic valve replacement (TAVR) remains an important issue. The aim of this study was to assess the value of a new discongruence index, to predict PPM after TAVR.Methods and Results: A total of 185 patients with severe aortic stenosis who underwent TAVR with the Edwards Sapien prosthesis or CoreValve Revalving system were included (Edwards valve, n=119; Core Valve Revalving system, n=66). Discongruence index was calculated pre-procedurally as the ratio of selected transcatheter valve size (mm) to body surface area (cm2). PPM was defined as effective orifice area (EOA) ≤0.85 cm2/m2 on transthoracic echocardiography before hospital discharge. Mean age was 82±5 years and 72 patients (38.9%) were men. The overall incidence of post-TAVR PPM was 35.1% (n=65). Discongruence index correlated with post-TAVR indexed EOA (y=0.18+0.057x; P<0.001). On multivariate logistic regression analysis, discongruence index was the only independent predictor of post-TAVR PPM (OR, 0.15; 95% CI: 0.03-0.66; P=0.012), and the area under the receiver operating characteristic curve was 0.62 (95% CI: 0.54-0.70, P=0.003), with an optimal cut-off point of 15.02 (sensitivity, 86.2%; specificity, 72.5%; positive predictive value, 74.3%; negative predictive value, 83.4%). CONCLUSIONS The new discongruence index may be useful tool to predict PPM after TAVR.

Abstract
We report the case of a pulsatile mass found in a patient who presented for a routine echocardiogram. The mass turned out to be an exceedingly rare mitral-subannular pseudoaneurysm involving the membranous atrioventricular septum with systolic expansion protruding into right atrium, discovered late after repeated multiple valve replacement surgery. Although these pseudoaneurysms may present asymptomatically, surgical intervention might be indicated because of the risk of rupture. This report describes this rare finding, discusses possible pathophysiological mechanisms, and underscores the importance of multimodality imaging to achieve correct identification and delimitation to guide surgical intervention in such cases.

Abstract
Myocardial infarction and sudden cardiac death are frequently the first manifestation of coronary artery disease. For this reason, screening of asymptomatic coronary atherosclerosis has become an attractive field of research in cardiovascular medicine. Necropsy studies have described histopathological changes associated with the development of acute coronary events. In this regard, thin-cap fibroatheroma has been identified as the main vulnerable coronary plaque feature. Hence, many imaging techniques, such as coronary computed tomography, cardiac magnetic resonance or positron emission tomography, have tried to detect noninvasively these histomorphological characteristics with different approaches. In this article, we review the role of these diagnostic tools in the detection of vulnerable coronary plaque with particular interest in their advantages and limitations as well as the clinical implications of the derived findings.

Early gadolinium enhancement in hypertrophic cardiomyopathy: a potential premature marker of myocardial damage. Int J Cardiovasc Imaging 2016; 32:1635-1643.

Abstract
Early gadolinium enhancement (EGE), one CMR diagnostic criteria in acute myocarditis, has been related with hyperemia and capillary leakage. The value of EGE in hypertrophic cardiomyopathy (HCM) remains unknown. Our aim was to determine the prevalence of EGE in patients with HCM, and its relation with late gadolinium enhancement (LGE). The association of EGE with morphological and clinical parameters was also evaluated. Sixty consecutive patients with HCM and CMR from our center were included. All the clinical and complementary test information was collected prospectively in our HCM clinic. Left ventricular (LV) measurements were calculated from cine sequences. EGE and LGE were quantified with a dedicated software. Clinical events were collected from medical records. A slow wash-out pattern on EGE was detected in up to 68 % of the patients, being an isolated finding without LGE in 10 (16 %). This cohort showed a greater maximal LV wall thickness (20.1 ± 4 vs. 18.1 ± 3.5 mm, p = 0.010) and asymmetry ratio (1.86 ± 0.42 vs. 1.62 ± 0.46; p = 0.039). The percentage of EGE/slice and the difference with the percentage LGE/slice demonstrated a significant positive correlation with the maximal LV wall thickness (Rho 0.450 and 0.386 respectively). EGE also correlated with number of segments with LVH (LV hypertrophy) and the asymmetry ratio. Neither EGE nor LGE were associated with classical risk factors, the risk score for sudden cardiac death, or with major clinical events. EGE was a frequent finding in HCM, even in absence of LGE. This phenomenon showed a positive correlation with morphological markers of disease burden.

Characterization and clinical significance of right ventricular mechanics in pulmonary hypertension evaluated with cardiovascular magnetic resonance feature tracking. J Cardiovasc Magn Reson 2016; 18:39.

Abstract
BACKGROUND Prognosis in pulmonary hypertension (PH) is related to right ventricular (RV) function. Quantification of RV mechanics may offer additive value. The objective of our study is to determine the feasibility and clinical and prognostic value of RV strain analysis by cardiovascular magnetic resonance (CMR) based feature tracking (FT) in PH. METHODS We retrospectively enrolled 116 patients (age 52.2 ± 12 years, 73.6 % women) referred to CMR for PH evaluation who underwent right heart catheterization within 1 month. Using dedicated FT software, peak global longitudinal and circumferential RV strain and strain rates (GLS, GCS, GLSR, and GCSR, respectively) were quantified from standard cine images. Using multivariate regression analysis, we evaluated the associations of strain with a composite endpoint of death, lung transplantation, or functional class deterioration. RESULTS RV strain analysis was feasible in 110 (95 %) patients. Patients were classified into: Group A (no PH, normal right ventricular ejection fraction [RVEF]; n = 17), Group B (PH, normal RVEF; n = 26), or Group C (PH, abnormal RVEF; n = 67). All strain and strain rate values were reduced in Group C. Furthermore, GCSR was significantly reduced in Group B (-0.92 [-1.0/-0.7]; p < 0.001) compared to Group A (-1.12 [-1.3/-0.9]; p < 0.001). After adjustment for six clinically meaningful covariates, GLS (hazard ratio 1.06; p = 0.026), GLSR (hazard ratio 2.52; p = 0.04), and GCSR (hazard ratio 4.5; p = 0.01) were independently associated with the composite endpoint. GCSR successfully discriminated patients with and without events (p = 0.01). CONCLUSIONS Quantification of RV strain with CMR-FT is feasible in the majority of patients, correlates with disease severity, and is independently associated with poor outcomes in PH.

Abstract
OBJECTIVES The objective of this study was to identify the DNA of oral bacteria in placental samples from women with and without periodontitis who had or had not had preterm births and/or low birthweight (PB/LBW) neonates. METHODS Data were gathered from 57 puerperal women in relation to socio-demographic, gynaecological, and periodontal variables and to placental histomorphology. Fifty-seven biopsies, 28 from mothers with periodontitis, were taken aseptically from preterm placentas (n = 36) and from full-term placentas (n = 21). Total DNA was extracted, and the presence of 15 oral bacteria was assessed using Nested-PCR. RESULTS The placentas from women with periodontitis showed a higher prevalence of periodontopathogens compared to those from women without periodontitis (P = 0.009). Samples showed low prevalences of Actinomyces israelii, Parvimonas micra and Tannerella forsythia. An association was found between Eikenella corrodens in placenta and periodontitis (P = 0.002). The most ubiquitous bacterium, Fusobacterium nucleatum, was more prevalent in mothers with periodontitis and PB/LBW (P = 0.033). Porphyromonas gingivalis, Treponema denticola, Prevotella intermedia and Aggregatibacter actinomycetemcomitans were not detected. CONCLUSIONS These results, along with previous findings, show that oral bacteria may be normally present in the placenta, however, the levels of certain oral pathogens in the placenta would highly depend on the mother's periodontal state.

Abstract
BACKGROUND The SYNTAX score helps in the treatment decision in multivessel coronary disease. Coronary computed tomography angiography (CTA) can measure the SYNTAX score but has been used in few patients with multivessel disease. Our aim was to assess the feasibility, accuracy and reproducibility of SYNTAX score with CCTA compared with invasive coronary angiography (ICA) in de novo left main and/or 3-vessel disease. METHODS 57 patients with new left main and/or 3-vessel disease on ICA and a CCTA performed within the previous month were included. The SYNTAX score was calculated retrospectively for both modalities. Agreement for the global score, vessel score, different components and inter-readers was evaluated with intraclass correlation coefficient (ICC). The ability to classify SYNTAX score categories (low, intermediate and high) was assessed using weighted kappa (K) coefficient. RESULTS CCTA-based SYNTAX score showed an acceptable concordance (ICC=0.64) and good correlation (r=0.65, p<0.001) with ICA. ICC per vessel and component ranged from 0 to 0.73. There was good agreement classifying the SYNTAX score categories (K=0.53) and interobserver reproducibility (ICC=0.85). CCTA demonstrated high diagnostic accuracy (0.84) for detecting patients in the high score group. No patient with a high CCTA SYNTAX score had a low risk score by ICA that would suggest benefit from percutaneous revascularization. CONCLUSIONS CCTA showed good correlation, acceptable concordance, and high reproducibility for the quantification of the SYNTAX score in de novo left main and/or 3-vessel coronary disease. A high CCTA SYNTAX score identified a group of patients less likely to benefit from percutaneous coronary intervention.

Abstract
The noninvasive diagnosis of cardiac amyloidosis (CA) is often challenging. ECG abnormalities are common but lack both sensitivity and specificity. While some features on transthoracic echocardiography have confirmed the classical picture of CA, they have generally been validated against endomyocardial biopsy and thus are indicative of advanced disease. The ability of cardiac magnetic resonance to characterize the myocardium has opened a new door in the noninvasive diagnosis of CA, representing an opportunity to revisit the role of traditional ECG and transthoracic echocardiography diagnostic crtieria in earlier disease stages.

Abstract
Imaging techniques are essential in the clinical evaluation of patients with a myocardial infarction. They are of value for both initial assessment of the ischemic injury and for detection of the subgroup of patients at higher risk of developing cardiovascular events during follow-up. Echocardiography remains the technique of choice for the initial evaluation, owing to its bedside capability to determine strong predictors, such as ventricular volumes, global and regional systolic function, and valvular regurgitation. New techniques for evaluating ventricular mechanics, mainly assessment of ventricular deformation, are revealing important aspects of post-infarction ventricular adaptation. The main alternative to echocardiography is cardiac magnetic resonance imaging. This technique is highly accurate for determining ventricular volumes and ventricular function and has the additional advantage of being able to characterize the myocardium and demonstrate changes associated with the ischemic insult such as necrosis/fibrosis, edema, microvascular obstruction, and intramyocardial hemorrhage. These features not only allow detection and quantification of the infarct size, but also reveal additional characteristics of the scar tissue with prognostic value.

Abstract
OBJECTIVES The goal of this study was to evaluate the diagnostic value of CMR features for the differential diagnosis of cardiac masses. BACKGROUND Differentiation of cardiac tumors and thrombi and differentiation of benign from malignant cardiac neoplasms is often challenging but important in clinical practice. Studies assessing the value of cardiac magnetic resonance (CMR) in this regard are scarce. METHODS We reviewed the CMR scans of patients with a definite cardiac thrombus or tumor. Mass characteristics on cine, T1-weighted turbo spin echo (T1w-TSE) and T2-weighted turbo spin echo (T2w-TSE), contrast first-pass perfusion (FPP), post-contrast inversion time (TI) scout, and late gadolinium enhancement (LGE) sequences were analyzed. RESULTS There were 84 thrombi, 17 benign tumors, and 25 malignant tumors in 116 patients. Morphologically, thrombi were smaller (median area 1.6 vs. 8.5 cm(2); p < 0.0001), more homogeneous (99% vs. 46%; p < 0.0001), and less mobile (13% vs. 33%; p = 0.007) than tumors. Hyperintensity compared with normal myocardium on T2w-TSE, FPP, and LGE were more common in tumors than in thrombi (85% vs. 42%, 70% vs. 4%, and 71% vs. 5%, respectively; all p < 0.0001). A pattern of hyperintensity/isointensity (compared with normal myocardium) with short TI and hypointensity with long TI was very frequent in thrombi (94%), rare in tumors (2%), and had the highest accuracy (95%) for the differentiation of both entities. Regarding the characterization of neoplastic masses, malignant tumors were larger (median area 11.9 vs. 6.3 cm(2); p = 0.006) and more frequently exhibited FPP (84% vs. 47%; p = 0.03) and LGE (92% vs. 41%; p = 0.001). The ability of CMR features to distinguish benign from malignant neoplasms was moderate, with LGE showing the highest accuracy (79%). CONCLUSIONS CMR features demonstrated excellent accuracy for the differentiation of cardiac thrombi from tumors and can be helpful for the distinction of benign versus malignant neoplasms.

Abstract
We report a case of hookworm parasitosis in a Spanish patient who before imprisonment had lived in Brazil. The diagnosis was established from a progressive manifestation of asthenia, together with significant weight loss. Laboratory tests showed hypochromic microcytic anemia and eosinophilia. Consequently, the patient was admitted to hospital in order to complete the study, where several hookworm eggs were later found in feces. The patient was subsequently treated with Albendazole and iron,achieving clinical cure, normalization of biochemical parameters and eventual eradication of the parasite. We believe it is important for the prison doctor to bear this and other parasitosis in mind when facing the case of inmates who are originally from tropical countries, where these parasites are endemic. In addition, it might be appropriate to implement parasite screening programs in the immigrant population headed by the Prison Health Service, even when said population is asymptomatic.

Abstract
Patients with diabetes mellitus (DM) have a higher incidence of infections, and those with bacteremia are more prone to develop sepsis and infective endocarditis (IE). Nevertheless, data concerning the impact of DM on the prognosis of patients with IE are limited and sometimes contradictory. We examined the impact of DM on the inhospital outcome of left-sided IE in a large cohort of patients. We studied 594 consecutive episodes of left-sided IE diagnosed at 3 tertiary care centers. They were divided into 2 groups: episodes in patients with DM (n = 114) and episodes in patients without DM (n = 480). We retrospectively analyzed the influence of DM therapy on patient outcome. Compared to patients without DM, patients with DM were older (67 ± 10 vs. 60 ± 15 yr; p < 0.001), less frequently male (53.5% vs. 67.9%; p = 0.004), and more commonly had chronic renal failure (23.9% vs. 6.9%; p < 0.001) and chronic obstructive pulmonary disease (14.6% vs. 7.8%; p = 0.019). Enterococcus (14.9% vs. 7.4%; p = 0.011) and Streptococcus bovis (8.8% vs. 3.8%; p = 0.024) were isolated more frequently. In the univariable analysis, septic shock (29.2% vs. 16.4%; p = 0.005) and mortality (43.5% vs. 30.0%; p = 0.008) were more common among patients with DM than in those without. Considering the different treatments for DM, septic shock (33.3%; p = 0.011) and death (50.8%; p = 0.012) were more frequent in patients receiving oral medication to treat diabetes than in patients with the other treatment modalities. However, multivariable analysis showed that DM had an independent association with development of septic shock (OR 2.282; 95% CI 1.186-4.393), but it was not a predictor of inhospital mortality.Staphylococci were the most frequently involved microorganisms in all patients; however, Enterococcus and Streptococcus bovis were more frequently isolated from individuals with DM and left-sided IE, whereas viridans group streptococci were more commonly isolated from those with left-sided IE who did not have DM. DM was independently associated with the development of septic shock, but it was not an independent predictor of inhospital mortality in patients with left-sided IE.
