RESUMEN

BACKGROUND: Intermittent ventricular pre-excitation was considered a low-risk marker for sudden death. However, to date, some studies do not exclude the existence of accessory pathways (APs) with high-risk intermittent antegrade conductive properties. According to current European Guidelines, high-risk features of APs are antegrade pathway conduction ≤250 ms in baseline or during the adrenergic stimulus, inducibility of atrioventricular reciprocating tachycardias (AVRT), inducibility of pre-excited atrial fibrillation (AF), and presence of multiple APs. For all of these transcatheter ablation is recommended. The aim of our study was to evaluate the existence of differences in risk characteristics between patients with intermittent pre-excitation (IPX) and those with persistent pre-excitation (PPX), from a sample of adults with ventricular pre-excitation and symptoms like palpitations. METHODS: 293 adults [IPX: 51 (17.4%); PPX: 242 (82.6%)] underwent electrophysiological study and then catheter ablation of their APs if arrhythmia inducibility (AVRT/AF) was noted, or, conversely, if it was appreciated a fast AP antegrade conduction, in baseline or during intravenous isoproterenol infusion, or if multiple APs were detected. RESULTS: There were no statistically significant differences in demographic characteristics (age and gender), AVRT/AF inducibility, antegrade conductive properties, the prevalence of multiple APs, and APs locations between IPX and PPX patients. CONCLUSIONS: In our study, patients with IPX did not show significant differences in clinical and electrophysiological features versus PPX patients.

RESUMEN

BACKGROUND: It was not yet fully established whether the use of antiplatelet agents (APAs) is associated with an increased risk of colorectal post-polypectomy bleeding (PPB). Temporarily, discontinuation of APAs could reduce the risk of PPB, but at the same time, it could increase the risk of cardiovascular disease recurrence. This study aimed to assess the PPB risk in patients using APAs compared to patients without APAs or anticoagulant therapy who had undergone colonoscopy with polypectomy. METHODS: A systematic electronic search of the literature was performed using PubMed/MEDLINE, Scopus, and CENTRAL, to assess the risk of bleeding in patients who do not interrupt single antiplatelet therapy (P2Y12 inhibitors or aspirin) and undergone colonoscopy with polypectomy. RESULTS: Of 2417 identified articles, 8 articles (all of them were non-randomized studies of interventions (NRSI); no randomized controlled trials (RCT) were available on this topic) were selected for the meta-analysis, including 1620 patients on antiplatelet therapy and 13,321 controls. Uninterrupted APAs single therapy was associated with an increased risk of PPB compared to the control group (OR 2.31; CI 1.37-3.91). Patients on P2Y12i single therapy had a higher risk of both immediate (OR 4.43; CI 1.40-14.00) and delayed PPB (OR 10.80; CI 4.63-25.16) compared to the control group, while patients on aspirin single therapy may have a little to no difference increase in the number of both immediate and delayed PPB events. CONCLUSIONS: Uninterrupted single antiplatelet therapy may increase the risk of PPB, but the evidence is very uncertain. The risk may be higher in delayed PPB. However, in deciding to discontinue APAs before colonoscopy with polypectomy, the potential higher risk of major adverse cardiovascular events should always be assessed.

RESUMEN

OBJECTIVES: To assess changes in working patterns and education experienced by radiology residents in Northwest Italy during the COVID-19 pandemic. METHODS: An online questionnaire was sent to residents of 9 postgraduate schools in Lombardy and Piedmont, investigating demographics, changes in radiological workload, involvement in COVID-19-related activities, research, distance learning, COVID-19 contacts and infection, changes in training profile, and impact on psychological wellbeing. Descriptive and χ2 statistics were used. RESULTS: Among 373 residents invited, 300 (80%) participated. Between March and April 2020, 44% (133/300) of respondents dedicated their full time to radiology; 41% (124/300) engaged in COVID-19-related activities, 73% (90/124) of whom working in COVID-19 wards; 40% (121/300) dedicated > 25% of time to distance learning; and 66% (199/300) were more involved in research activities than before the pandemic. Over half of residents (57%, 171/300) had contacts with COVID-19-positive subjects, 5% (14/300) were infected, and 8% (23/300) lost a loved one due to COVID-19. Only 1% (3/300) of residents stated that, given the implications of this pandemic scenario, they would not have chosen radiology as their specialty, whereas 7% (22/300) would change their subspecialty. The most common concerns were spreading the infection to their loved ones (30%, 91/300), and becoming sick (7%, 21/300). Positive changes were also noted, such as being more willing to cooperate with other colleagues (36%, 109/300). CONCLUSIONS: The COVID-19 pandemic changed radiology residents' training programmes, with distance learning, engaging in COVID-19-related activities, and a greater involvement in research becoming part of their everyday practice. KEY POINTS: • Of 300 participants, 44% were fully dedicated to radiological activity and 41% devoted time to COVID-19-related activities, 73% of whom to COVID-19 wards. • Distance learning was substantial for 40% of residents, and 66% were involved in research activities more than before the COVID-19 pandemic. • Over half of residents were exposed to COVID-19 contacts and less than one in twenty was infected.

RESUMEN

OBJECTIVES: to investigate heart failure (HF) hospitalizations, the following one-year follow-up, and any possible connection between rehospitalizations due to HF and patients' characteristics derived from administrative databases. DESIGN: retrospective longitudinal design. SETTING AND PARTICIPANTS: the study was conducted analyzing public hospital records of a district in Abruzzo Region (Central Italy), which counts more than 300,000 inhabitants. Patients hospitalized for HF from 01.01.2016 to 31.12.2017 (index event) were included in the study and followed-up for one year. MAIN OUTCOME MEASURES: frequency of repeated hospital admissions, time intervals from the index HF hospitalizations, and causes of readmissions were investigated. RESULTS: a total of 1,587 patients discharged alive after an index hospitalization for HF were included in the study. The mean age of the patients was 79.6 years and the majority of them were females (53.7%). The mean length of stay (LOS) for the index hospitalizations was 8.8 ±6.8 days. During the follow-up period, 336 (21.2%) patients underwent one to four repeated hospitalizations for HF. The first readmission due to HF occurred after a median time of 106.5 days from the index event discharge, and for 20.0% of all cases it occurred within 31 days; 453 patients (28.6%) were readmitted exclusively for other causes, and 67 (4.2%) died out of hospital without any previous HF re-hospitalization. When the outcome was considered as a composite endpoint (out-of-hospital death/HF re-hospitalization), age >=75 (HR 1.737; 95%CI 1.330-2.267), LOS at the index hospitalization >=8 days (HR 1.302; 95%CI 1.066-1.591), and repeated hospitalizations for other causes (HR 1.789; 95%IC 1.465-2.185) were associated with the risk of repeated hospitalizations for HF. CONCLUSIONS: this study shows that about one HF patient out of five experienced at least one re-hospitalization for HF within one year from index hospitalization. In addition to having a longer index hospitalization, these patients were older and frequently suffered from comorbidities which also led to hospitalizations. The results underline the need for a close and careful follow-up after the discharge of old HF patients with multiple pathologies in order to avoid further HF admissions in a short time.

RESUMEN

BACKGROUND: Pulmonary vein isolation is the cornerstone of catheter ablation in patients with atrial fibrillation (AF). However, with advanced left atrial (LA) structural changes, additional targeted catheter ablation of low-voltage zones (LVZs) has produced favorable results. Therefore, with the advent of single-shot techniques, it would be helpful to predict the presence of LVZs before an ablation procedure. OBJECTIVE: We hypothesized that computed tomography (CT)-derived left atrial volume index (LAVI), in combination with other objective parameters, could be used to develop a score able to predict the presence of LVZs. METHODS: In a large cohort of patients undergoing their first AF ablations, comprehensive echocardiographic evaluations and cardiac CT were performed. During the electrophysiological studies, LA geometry and electroanatomic voltage maps were created. LVZs were defined as areas ≥1 cm2 with bipolar peak-to-peak voltage amplitudes ≤0.5 mV. RESULTS: In a derivation cohort of 374 patients, predictors of LVZs were identified by regression analysis and used to build the Zentralklinik Bad Berka and University of L'Aquila (ZAQ) score (age ≥65 years; female sex; and CT-LAVI ≥57 mL/m2 ). The ZAQ score of 2 points accurately identified the presence and the extent of LVZs (area under the curve [AUC], 0.809; 95% confidence interval [CI], 0.758-0.861; P < .001 and 3 [interquartile range, IQR, 1.5-4.5] vs 7 cm2 [IQR 4-9]; P = .001). In a validation cohort of 103 patients, the predictive value of the score was confirmed (AUC, 0.793; 95% CI, 0.709-0.878; P < .001 and 4 [IQR, 2-7] vs 11.5 cm2 [IQR, 8-16.5]; P = .001). CONCLUSIONS: The ZAQ score identifies LVZs and may be useful for planning the ablation strategy ahead of time.

RESUMEN

BACKGROUND AND OBJECTIVE: Atrial Fibrillation (AF) is associated with an increased risk of stroke and development of cognitive impairment. Our cross-sectional study aims to identify risk factors for cognitive impairment in patients with permanent AF. MATERIALS AND METHODS: 212 consecutive outpatients with history of permanent AF lasting more than 1 year were enrolled and the Short Portable Mental Status Questionnaire (SPMSQ) was used to assess cognitive impairment (number of errors ≥5). The type of antithrombotic therapy, the time in therapeutic range (TTR) in case of treatment with warfarin and the degree of heart rate (HR) control (upon Holter ECG monitoring) were also assessed. RESULTS: ROC curve analysis indicated that TTR was associated with cognitive impairment (AUC 0.85 ± 0.03; 95% CI 0.77-0.88; p < 0.0001). Multivariate logistic regression analysis showed an independent association of previous cerebrovascular or cardiovascular events (OR 7.24, 95% CI 1.37-38.25; p = 0.020), aspirin therapy instead of anticoagulant therapy (OR 24.74, 95% CI 1.27-482.12; p = 0.034), warfarin use with TTR ≤60% (OR 21.71 , 95%CI 4.35-108; p < 0.001) and an average daily HR either <60 bpm or >100 bpm (OR 6.04, 95% 1.09-33.29; p = 0.039) with cognitive impairment. CONCLUSION: Among patients with permanent AF, cognitive impairment is more frequent in those with inadequate antithrombotic therapy (aspirin therapy instead of anticoagulant therapy) and with suboptimal oral anticoagulation (TTR ≤60%) or heart rate control. Efforts should be made to optimize therapies related to these parameters.

RESUMEN

Background and objectives: Electrocardiograph abnormalities (i.e., QT interval prolongation) have been described in inflammatory bowel diseases (IBD). We aimed to measure the QT interval in a cohort of patients with IBD and to analyze its relationship with clinical and inflammatory activity. Materials and Methods: We performed a cross-sectional study that included 38 IBD outpatients and 38 "age- and sex-matched" healthy controls. Nine patients had active IBD, and 29 were in clinical remission. Among the latter, 10 patients had sustained (lasting >1 year) and 19 had short-term remission (≤1 year). Corrected QT (QTc) interval was measured on standard 12-lead electrocardiograph. A systematic review of the literature on studies investigating the QT interval in patients with IBD was also performed. Results: QTc interval values were similar between IBD patients and healthy controls (417.58 ± 22.05 ms vs. 409.13 ± 19.61 ms, respectively; p: 0.479). Patients with active IBD had significantly higher QTc values (435.11 ± 27.31 ms) than both controls (409.13 ± 19.61 ms) and patients in remission (412.14 ± 17.33 ms) (p: 0.031). Post hoc analysis showed that the difference in QTc values between active IBD and remission was attributable to the group of patients with sustained remission (p < 0.05). Lastly, a significant correlation between QTc interval and C-reactive protein (CRP) values was observed (Spearman test: r = 0.563; p: 0.0005). Conclusions: Our study demonstrates an association between QTc duration and both clinical and inflammatory activity in patients with IBD. The higher the CRP value, the longer is the QTc duration. For practical purposes, all patients with active IBD should undergo a standard ECG. Prescription of drugs able to modify the QT interval should be avoided in patients with active IBD. The systematic review of the literature indicated that this is the first published study demonstrating an association between the QTc duration and CRP values in patients with IBD.

RESUMEN

PURPOSE: Electroanatomical mapping (EAM) could increase cardiac magnetic resonance imaging (CMR) sensitivity in detecting ventricular scar. Possible bias may be scar over-estimation due to inadequate tissue contact. Aim of the study is to evaluate contact-force monitoring influence during EAM, in patients with idiopathic right ventricular arrhythmias. METHODS: 20 pts (13 M; 43 ± 12 y) with idiopathic right ventricular outflow tract (RVOT) arrhythmias and no structural abnormalities were submitted to Smarttouch catheter Carto3 EAM. Native maps included points collected without considering contact-force. EAM scar was defined as area ≥1 cm2 including at least 3 adjacent points with signal amplitude (bipolar <0.5 mV, unipolar 3,5 mV), surrounded by low-voltage border zone. EAM were re-evaluated offline, removing points collected with contact force <5 g. Finally, contact force-corrected maps were compared to the native ones. RESULTS: An EAM was created for each patient (345 ± 85 points). After removing poor contact points, a mean of 149 ± 60 points was collected. The percentage of false scar, collected during contact force blinded mapping compared to total volume, was 6.0 ± 5.2% for bipolar scar and 7.1 ± 5.9% for unipolar scar, respectively. No EAM scar was present after poor contact points removal. Right ventricular areas analysis revealed a greater number of points with contact force < 5 g acquired in free wall, where reduced mean bipolar and unipolar voltage were recorded. CONCLUSIONS: To date this is the first work conducted on structurally normal hearts in which contact-force significantly increases EAM accuracy, avoiding "false scar" related to non-adequate contact between catheter and tissue.

RESUMEN

PURPOSE OF THE REVIEW: An increased prevalence of cardiovascular risk factors in rheumatoid arthritis (RA) is reported. The absolute cardiovascular risk in RA patients is higher than in the general population, and although the RA prognosis has gradually improved, premature cardiovascular (CV) mortality remains a matter of fact. The purpose of this review is to shed light on CV and metabolic involvement in RA, with the aim of defining its best management. RECENT FINDINGS: Multiple lines of evidence have revealed common mechanisms behind inflammatory and CV diseases and clarified the metabolic and CV pathways involved in RA and the effects of different pharmacological treatments. CV risk assessment should be mandatory in all RA patients, taking into account the impact of both diseases on patient's prognosis. Therefore, a multidisciplinary approach is the best management, and rheumatologists, cardiologists, and general practitioners must work together to significantly improve outcome and quality of life in RA patients. Future research could investigate the potential beneficial effects of a more aggressive pharmacological treatment of CV and metabolic risk factors.

RESUMEN

BACKGROUND: Radiation exposure is an important issue for interventional cardiologists that is often underevaluated. Our aim was to evaluate determinants of operator radiation exposure during percutaneous coronary procedures. METHODS: The RADIANT (NCT01974453) is a prospective, single-center observational study involving 4 expert operators and 2 fellows performing percutaneous coronary procedures. The operator radiation dose was evaluated using dedicated electronic dosimeters in 2,028 procedures: 1,897 transradial access (TRA; 1,120 right and 777 left TRA) and 131 transfemoral access (TFA). RESULTS: In the whole population, operator radiation dose at the thorax did not differ between TFA (9µSv [interquartile range 5-18µSv]) and TRA (9µSv [4-21µSv]), but after propensity score matching analysis, TFA showed lower dose (9µSv [5-18µSv]) compared with TRA (17µSv [9-28µSv], P<.001). In the whole transradial group, left TRA (5µSv [2-12µSv]) was associated with significant lower operator dose compared with right TRA (13µSv [6-26µSv], P<.001).The use of adjunctive protective pelvic drapes was significantly associated with lower radiation doses compared with procedures performed without drapes (P<.001). Among the operators, an inverse relation between height and dose was observed. Finally, left projections and the use of angiographic systems not dedicated for coronary and high frame rates were all associated with a significant higher operator radiation exposure. CONCLUSIONS: In a high-volume center for transradial procedures, TFA is associated with lower operator radiation dose compared with TRA. The use of adjunctive anti-rx drapes seems a valuable tool to reduce the higher operator radiation exposure associated with TRA.

RESUMEN

OBJECTIVES: The aim of this prospective study was to evaluate muscle force of the hand, thumb, and forefinger in patients with prolonged radial occlusion after transradial percutaneous coronary procedures. BACKGROUND: There are no data on hand strength and function in patients with prolonged radial occlusion after percutaneous coronary procedures. METHODS: Elective patients with chronic stable angina undergoing percutaneous coronary procedures were evaluated the day before the procedure for radial artery patency, Allen test, hand grip, and thumb and forefinger pinch tests. The same measures were performed the day after the procedure and at follow-up. At follow-up, patients were divided in two groups according to the radial patency (group 1) or occlusion (group 2). RESULTS: Of the 99 patients included in the study, 90 patients had a patent radial artery (group 1), and nine (9.1%) patients had an occluded artery (group 2). At baseline, there were no significant differences in hand grip test between the two groups (42 ± 11 kg in group 1 and 41 ± 17 kg in group 2, P = 0.74). In both groups, after the procedure, the hand grip test values was significantly reduced compared with baseline values (40 ± 11 kg in group 1, P < 0.0001 and 37 ± 17 kg in group 2, P = 0.007). Finally, at follow-up, in both groups, the hand grip test values returned to baseline values. Thumb and forefinger pinch tests did not show significant differences after the procedure and at follow-up, compared with baseline. CONCLUSIONS: Radial artery occlusion after percutaneous coronary procedures was not associated with a reduction in hand and finger strength.

RESUMEN

BACKGROUND: Anthracyclines and taxanes are effective drugs in breast cancer (BC), but their toxicity profiles limit their use in combination. A dose-finding study was performed to determine maximum tolerated doses (MTDs) of nonpegylated liposomal doxorubicin (TLC-D99) and docetaxel (DTX) as a dose-dense schedule, to maintain dose intensity, and to limit toxicity, particularly cardiac. METHODS: Twenty-four patients were enrolled, 12 with metastatic BC, 5 with locally advanced BC, and 7 with early BC. An intra- and interpatient approach was planned in two sequential steps. In the first step, TLC-D99 was administered at dose levels of 40, 45, and 50 mg/m(2) plus DTX at a fixed dose of 50 mg/m(2). In the second step, TLC-D99 was administered at the dose established in the first step plus DTX at dose levels of 55, 60, and 65 mg/m(2). Every treatment cycle was delivered on day 1 every 14 days. Pegylated granulocyte colony-stimulating factor was scheduled on day 2. Dose-limiting toxicities (DLTs) were defined as G4 hematological; G3 nonhematological; ≥10% or ≥20% left ventricular ejection fraction (LVEF) reduction if the final value was <50% or ≥50%, respectively; severe arrhythmia; and symptomatic heart failure. LVEF was evaluated by echocardiography every two cycles, and precursor brain natriuretic peptide (pBNP) and cardiac troponin I (cTnI) were monitored on days 1 and 2. RESULTS: Five DLTs occurred (20.8%). No cardiac event of congestive heart failure was reported; 2 events of grade 3 cardiac dysfunction (8.3%), including a ≥20% LVEF reduction in 1 patient and symptomatic arrhythmia in another; 2 incidences of G4 neutropenia (8.3%); and 1 occurrence of G3 asthenia (4.2%) were reported. MTDs were not reached. The recommended doses were established as TLC-D99 50 mg/m(2) and DTX 65 mg/m(2). Cumulatively, mild (G1-G2) cardiac dysfunction was observed in 58.4% of patients: G1 cardiac arrhythmia was noted in 50%, G1-G2 general cardiac toxicity occurred in 25%, and concomitant toxicity was present in 17%. cTnI never increased. pBNP was increased in 25% and was associated with limiting arrhythmia in 4% and cardiac dysfunction in 16%. CONCLUSION: Dose-dense TLC-D99 50 mg/m(2) and DTX 65 mg/m(2) can be safely administered in combination every 2 weeks for breast cancer, with the highest projected dose intensity for each drug at 25 and 32.5 mg/m(2) per week, respectively.

RESUMEN

OBJECTIVE: Investigation on recent cases of tinea genitalis after travelling to South East Asia. METHODS: Patients with tinea in the genital region, which emerged after sex in South East Asia, underwent further assessment including microscopy, cultures and DNA analyses. RESULTS: The case series includes seven patients. In six patients, Trichophyton interdigitale (former Trichophyton mentagrophytes) was detected. Three patients suffered from a severe inflammatory reaction of the soft tissue and two of them needed hospitalisation due to severe pain. In four patients, cicatrising healing was noticed. Five patients were declared incapacitated for work. CONCLUSIONS: Sexual activity should be considered as a potentially important and previously underappreciated means of transmission of T. interdigitale. To avoid irreversible scarring alopecia, prompt initiation of antifungal treatment is essential and adequate isolation and identification of the pathogen is mandatory.

RESUMEN

BACKGROUND: Aim of the study was to explore the relationship between emotional dimensions of hypertensive patients and the self-care skills; we tried to draw the psychological aspects could impact the health management in hypertension analyzing the effect of emotional regulation on self-care skills: our scope was to highlight the psychological dynamics into behavioral medicine approach. METHODS: In an observational study design, patients were collected. Patients with diagnosis of hypertension were recruited in primary care setting. Inclusion criteria included patients older than 18 years, with known and medically treated primary hypertension undergoing antihypertensive medication. RESULTS: Statistical analysis was carried out based on the data of 28 primary hypertensive patients (seven females, 21 males, mean age ± SD: 49.8 ± 7.8 years mean; clinic blood pressure: mean systolic blood pressure: 137.2 ± 13.1 mmHg, mean diastolic blood pressure: 82.1 ± 9.9 mmHg). Mean duration of hypertension in the sample was 13.1 years (±8.2 years). Correlations among the main variables of interest showed a positive and significant relationship between emotional dysregulation indexes, psychological distress, and self-care domains: awareness resulted negatively and significantly correlated to self-efficacy; nonacceptance, goals and impulse indexes seemed positively and significantly correlated to anxiety and depression; finally, stress was correlated positively and significantly to awareness and impulse. CONCLUSIONS: Evidencing the role of emotion dysregulation on self-care skills and psychological outcomes, and specifically highlighting the impact of emotion dysregulation on self-care, our findings could inform the development and implementation of psychological interventions aimed at promoting psychological well-being and healthy behavior by focusing on the promotion of emotion regulation strategies, to reduce the risk for co-morbidity and/or severe cardiovascular diseases.

RESUMEN

Purpose: Atrioesophageal fistula is one of the most feared complications of radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) as it is associated with high mortality. Determining the esophagus location during RFCA might reduce the risk of esophageal injury. The present study aims to evaluate the feasibility of using intracardiac echocardiography integrated into a 3-dimensional electroanatomical mapping system (ICE/3D EAM) for the assessment of esophageal position and shifts in response to ablation. Methods: We prospectively enrolled 20 patients that underwent RFCA of AF under conscious analgosedation. The virtual anatomy of the left atrium, the pulmonary vein (PV) ostia, and the esophagus was created with ICE/3D EAM. The esophageal positions were obtained at the beginning of the procedure and then after left and right PV isolation (PVI). Esophageal shifts were measured offline after the procedure using the tools available in the 3D EAM system. Results: Most esophagi moved away from the ablated PV ostia. After the left PVI, the median of the shifts was 2.8 mm (IQR 1.0-6.3). In 25% of patients, the esophagus shifted by >5.0 mm (max. 13.4 mm). After right PVI, the median of shifts was 2.0 mm (IQR 0.7-4.9). In 10% of patients, the esophageal shift was >5.0 mm (max. 7.8 mm). Conclusions: ICE/3D EAM enables the intraprocedural visualization of baseline esophageal position and its shifts after PVI. The shifts are variable, but they tend to be small and directed away from the ablation site. Repeated intraprocedural visualization of the esophagus may be needed to reduce the risk of esophageal injury.

RESUMEN

Atrial fibrillation (AF) is a common cardiac arrhythmia that poses a significant risk of stroke and thromboembolic events. Anticoagulation therapy is essential for preventing stroke in patients with AF. An increasing number of people of all ages, including cardiac patients, approach physical activity as both a leisure-time exercise and a competitive sport. Therefore, patients at risk of AF are increasingly allowed to practice sports activities. Management of oral anticoagulant therapy (OAT) in these patients is extremely challenging because of the need to balance the risks and benefits of medications, considering both hemorrhagic (in case of trauma) and ischemic complications when the drugs are avoided. Official recommendations are limited for these patients and forbid sports that increase the risk of trauma and consequent bleeding in most cases. These recommendations are strongly influenced by the "traditional" management of OAT, which mainly involves coumarin derivatives. Non-vitamin K antagonist direct oral anticoagulants (DOACs), with their more favorable pharmacokinetic-pharmacodynamic profile than that of coumarin derivatives, may represent an opportunity to modify the approach to sports activity in patients with AF and indications for OAT. This study aimed to review the use of anticoagulants in athletes with AF, highlight their efficacy and safety, and provide practical considerations regarding their management.

RESUMEN

Cardiac tumors, due to the various clinical scenarios and their histological subtypes, are still challenging for clinicians. They are differentiated into primary and secondary. The latest are more common and are usually lung and breast cancers, melanomas, and lymphoma metastasis. We present a case of a 73-year-old woman, with a history of breast cancer 10 years earlier, admitted to Cath lab for an elevation of the ST-segment of the electrocardiogram, myocardial infarction. Echocardiogram showed a curious abnormality in the myocardial wall. Thanks to a multimodality imaging strategy, including contrast-enhanced echocardiography and cardiac magnetic resonance, characterization of the underlying pathology was clear and, thus, the appropriate management and therapy.


This is the case of a cardiac metastatic tumor, whose certain diagnosis can only be made by myocardial biopsy ­ an invasive sample of heart tissue ­ unfortunately not available in our case. Alternatively, we puzzled data from two second-level imaging techniques: contrast-enhanced cardiac ultrasound and cardiac magnetic resonance, which allowed us to better evaluate the nature of this cardiac mass. The former gave information about its blood supply, the latter gave information about tissue characterization. In this paper, we show how a complete integration of data from clinical and a stepwise multimodality imaging-based approach may allow a diagnosis in a complex clinical case.

RESUMEN

Heart failure (HF) represents a significant global health challenge that is still responsible for increasing morbidity and mortality despite advancements in pharmacological treatments. This review investigates the effectiveness of non-pharmacological interventions in the management of HF, examining lifestyle measures, physical activity, and the role of some electrical therapies such as catheter ablation, cardiac resynchronization therapy (CRT), and cardiac contractility modulation (CCM). Structured exercise training is a cornerstone in this field, demonstrating terrific improvements in functional status, quality of life, and mortality risk reduction, particularly in patients with HF with reduced ejection fraction (HFrEF). Catheter ablation for atrial fibrillation, premature ventricular beats, and ventricular tachycardia aids in improving left ventricular function by reducing arrhythmic burden. CRT remains a key intervention for selected HF patients, helping achieve left ventricular reverse remodeling and improving symptoms. Additionally, the emerging therapy of CCM provides a novel opportunity for patients who do not meet CRT criteria or are non-responders. Integrating non-pharmacological interventions such as digital health alongside specific medications is key for optimizing outcomes in HF management. It is imperative to tailor approaches to individual patients in this diverse patient population to maximize benefits. Further research is warranted to improve treatment strategies and enhance patient outcomes in HF management.

RESUMEN

The use of anticoagulation therapy could prove to be controversial when trying to balance ischemic stroke and intracranial bleeding risks in patients with concurrent cerebral amyloid angiopathy (CAA) and atrial fibrillation (AF). In fact, CAA is an age-related cerebral vasculopathy that predisposes patients to intracerebral hemorrhage. Nevertheless, many AF patients require oral systemic dose-adjusted warfarin, direct oral anticoagulants (such as factor Xa inhibitors) or direct thrombin inhibitors to control often associated with cardioembolic stroke risk. The prevalence of both CAA and AF is expected to rise, due to the aging of the population. This clinical dilemma is becoming increasingly common. In patients with coexisting AF and CAA, the risks/benefits profile of anticoagulant therapy must be assessed for each patient individually due to the lack of a clear-cut consensus with regard to its risks in scientific literature. This review aims to provide an overview of the management of patients with concomitant AF and CAA and proposes the implementation of a risk-based decision-making algorithm.

RESUMEN

AIMS: Right bundle branch block (RBBB) morphology non-sustained ventricular arrhythmias (VAs) have been associated with the presence of non-ischaemic left ventricular scar (NLVS) in athletes. The aim of this cross-sectional study was to identify clinical and electrocardiogram (ECG) predictors of the presence of NLVS in athletes with RBBB VAs. METHODS AND RESULTS: Sixty-four athletes [median age 39 (24-53) years, 79% males] with non-sustained RBBB VAs underwent cardiac magnetic resonance (CMR) with late gadolinium enhancement in order to exclude the presence of a concealed structural heart disease. Thirty-six athletes (56%) showed NLVS at CMR and were assigned to the NLVS positive group, whereas 28 athletes (44%) to the NLVS negative group. Family history of cardiomyopathy and seven different ECG variables were statistically more prevalent in the NLVS positive group. At univariate analysis, seven ECG variables (low QRS voltages in limb leads, negative T waves in inferior leads, negative T waves in limb leads I-aVL, negative T waves in precordial leads V4-V6, presence of left posterior fascicular block, presence of pathologic Q waves, and poor R-wave progression in right precordial leads) proved to be statistically associated with the finding of NLVS; these were grouped together in a score. A score ≥2 was proved to be the optimal cut-off point, identifying NLVS athletes in 92% of cases and showing the best accuracy (86% sensitivity and 100% specificity, respectively). However, a cut-off ≥1 correctly identified all patients with NLVS (absence of false negatives). CONCLUSION: In athletes with RBBB morphology non-sustained VAs, specific ECG abnormalities at 12-lead ECG can help in detecting subjects with NLVS at CMR.


In athletes with right bundle branch block (RBBB) morphology non-sustained ventricular arrhythmias (VAs), the presence of a non-ischaemic left ventricular scar (NLVS) may be highly suspected if one or more of the following electrocardiogram (ECG) characteristics are present at the 12-lead resting ECG: low QRS voltages in limb leads, negative T waves in inferior leads, negative T waves in limb leads I­aVL, negative T waves in precordial leads V4­V6, presence of left posterior fascicular block, presence of pathologic Q waves, and poor R-wave progression in right precordial leads. This score should be externally validated in a larger population of athletes with VAs. In athletes with RBBB morphology non-sustained Vas, attention should be placed on the 12-lead resting ECG to suspect the presence of an NLVS. In athletes with RBBB VAs and the presence of one or more of the identified ECG characteristics, a cardiac magnetic resonance with late gadolinium enhancement is useful to rule out an NLVS.
