Atypical presentation and percutaneous repair of ascending aortic pseudoaneurysm: a case report
Pseudoaneurisma aòrtic; Tancament percutani; SíncopePseudoaneurisma aórtico; Cierre percutáneo; SíncopeAortic pseudoaneurysm; Percutaneous closure; SyncopeBackground
Ascending aortic pseudoaneurysms (AAPs) are an unusual complication of cardiac or aortic surgery and are associated with a high risk of complications and mortality. Guidelines recommend surgical repair. There is few data concerning percutaneous occlusion of AAP. We present a case of syncope due to vascular and heart chamber compression by a large post-surgical AAP that was filled through a focal leak. Ascending aortic pseudoaneurysm was successfully occluded percutaneously.
Case summary
A 66-year-old man with a mechanical aortic prosthesis and a Dacron tube in the ascending aorta presented with syncope due to compression of the right atrium and superior vena cava by a large peritube collection. A computed tomography angiography (CTA) showed a large AAP that was filled through a small focal dehiscence of the tube proximal suture. Patient was dismissed for surgery due to high surgical risk. Then, AAP was successfully occluded percutaneously via a 6-French radial access and local anaesthesia.
Discussion
In patients with syncope and previous cardiac surgery, aortic complications should be ruled out. Although transthoracic echocardiography may be useful, CTA is the recommended diagnostic test for ruling out post-surgical AAP and allows the characterization of the number, localization, and size of the leaks. In selected patients with high surgical risk and favourable anatomic characteristics, a percutaneous closure could be indicated

Infective endocarditis is a life-threatening disease associated with high mortality. Appropriate antimicrobial treatment and cardiac surgery, when indicated, are closely related to prognosis. When cardiac surgery is contraindicated, prognosis worsens dramatically. There is few data concerning the use of transcatheter aortic valve replacement after healed aortic valve endocarditis or during active IE. We present the first case report of a transcatheter aortic valve replacement implanted during antimicrobial therapy for a severely symptomatic acute aortic regurgitation due to an infective endocarditis complicated with a perivalvular abscess.
Case summary
A 68-year-old man was admitted due to left hemiparesis and fever. An acute ischaemic stroke with haemorrhagic transformation was diagnosed. Blood cultures were positive for methicillin-susceptible Staphylococcus aureus and a transoesophageal echocardiogram revealed an aortic endocarditis with an acute severe aortic regurgitation and a perivalvular abscess. Urgent cardiac surgery was contraindicated due to intracranial haemorrhage. However, the patient developed refractory pulmonary oedema and haemodynamic instability. Despite the perivalvular abscess, a transcatheter aortic valve replacement was successfully performed 15 days after the diagnosis. Nine months after completing antimicrobial therapy, there were no signs of relapse.
Discussion
Transcatheter aortic valve replacement could be considered in selected patients with symptomatic severe aortic regurgitation due to aortic infective endocarditis during antimicrobial therapy when cardiac surgery is contraindicated
Bin-CE: A comprehensive web application to decide upon the best set of outcomes to be combined in a binary composite endpoint
The estimation of the Sample Size Requirement (SSR) when using a binary composite endpoint (i.e. two or more outcomes combined in a unique primary endpoint) is not trivial. Besides information about the rate of events for each outcome, information about the strength of association between the outcomes is crucial, since it can determine an increase or decrease of the SSR. Specifically, the greater the strength of association between outcomes the higher the SSR. We present Bin-CE, a free tool to assist clinicians for computing the SSR for binary composite endpoints. In a first step, the user enters a set of candidate outcomes, the assumed rate of events for each outcome and the assumed effect of therapy on each outcome. Since the strength of the association between outcomes is usually unknown, a semi-parametric approach linking the a priori clinical knowledge of the potential degree of association between outcomes with the exact values of these parameters was programmed with Bin-CE. Bin-CE works with a recursive algorithm to choose the best combination of outcomes that minimizes the SSR. In addition, Bin-CE computes the sample size using different algorithms and shows different figures plotting the magnitude of the sample size reduction, and the effect of different combinations of outcomes on the rate of the primary endpoint. Finally, Bin-CE is programmed to perform sensitivity analyses. This manuscript presents the mathematic bases and introduces the reader to the use of Bin-CE using a real example
Myocardial injury after major non-cardiac surgery evaluated with advanced cardiac imaging: a pilot study
Cardiac imaging; Myocardial injury; Noncardiac surgeryImatge cardíaca; Lesió del miocardi; Cirurgia no cardíacaImagen cardiaca; Lesión miocárdica; Cirugía no cardiacaBackground
Myocardial injury after non-cardiac surgery (MINS) is a frequent complication caused by cardiac and non-cardiac pathophysiological mechanisms, but often it is subclinical. MINS is associated with increased morbidity and mortality, justifying the need to its diagnose and the investigation of their causes for its potential prevention.
Methods
Prospective, observational, pilot study, aiming to detect MINS, its relationship with silent coronary artery disease and its effect on future adverse outcomes in patients undergoing major non-cardiac surgery and without postoperative signs or symptoms of myocardial ischemia. MINS was defined by a high-sensitive cardiac troponin T (hs-cTnT) concentration > 14 ng/L at 48–72 h after surgery and exceeding by 50% the preoperative value; controls were the operated patients without MINS. Within 1-month after discharge, cardiac computed tomography angiography (CCTA) and magnetic resonance imaging (MRI) studies were performed in MINS and control subjects. Significant coronary artery disease (CAD) was defined by a CAD-RADS category ≥ 3. The primary outcomes were prevalence of CAD among MINS and controls and incidence of major cardiovascular events (MACE) at 1-year after surgery. Secondary outcomes were the incidence of individual MACE components and mortality.
Results
We included 52 MINS and 12 controls. The small number of included patients could be attributed to the study design complexity and the dates of later follow-ups (amid COVID-19 waves). Significant CAD by CCTA was equally found in 20 MINS and controls (30% vs 33%, respectively). Ischemic patterns (n = 5) and ischemic segments (n = 2) depicted by cardiac MRI were only observed in patients with MINS. One-year MACE were also only observed in MINS patients (15.4%).
Conclusion
This study with advanced imaging methods found a similar CAD frequency in MINS and control patients, but that cardiac ischemic findings by MRI and worse prognosis were only observed in MINS patients. Our results, obtained in a pilot study, suggest the need of further, extended studies that screened systematically MINS and evaluated its relationship with cardiac ischemia and poor outcomes.The study has been supported by research grant from the Instituto de Salud Carlos III, Spain (PI16/01162), partly funded by Fondo Europeo de Desarrollo Regional (FEDER), Unión Europea, “Una manera de hacer Europa” to Ekaterine Popova, by Generalitat de Catalunya (PERIS SLT017/20/000089) to Ekaterine Popova and by a "Marato de TV3" grant (20150110) to Pablo Alonso-Coello
A Case of a Young Patient with Acute Endocarditis and Challenging Diagnostic and Treatment Decisions
Endocarditis infecciosa; Endocarditis protésicaEndocarditis infecciosa; Endocarditis protèsicaInfective endocarditis; Prosthetic endocarditisDespite advances achieved in recent years, Infective Endocarditis (IE) remains a disease associated with high mortality and morbidity. When it involves multiple locations at the same time, deciding the best treatment can become challenging. In some cases, especially in patients with prosthetic valve endocarditis, a definitive diagnosis can be difficult to achieve and multimodality imaging including Positron Emission Tomography/Computed Tomography Angiography (PET/CTA) has demonstrated improvement in the diagnostic yield. We present a case of a young patient with two previous thoracic surgeries who was admitted due to a severe Staphylococcus aureus IE affecting the mitral valve and presenting a questionable image in an aortic arch graft. This case illustrates the importance of the Endocarditis Team when it comes to difficult decisions regarding diagnosis and management in a disease with poor scientific evidence
Dynamics of Emergency Cardiovascular Hospital Admissions and In-Hospital Mortality During the COVID-19 Pandemic: Time Series Analysis and Impact of Socioeconomic Factors
COVID-19; Síndrome coronario agudo; Insuficiencia cardiacaCOVID-19; Síndrome coronària aguda; Insuficiència cardíacaCOVID-19; Acute coronary syndrome; Heart failureAims: This study aimed to evaluate the decline in urgent cardiovascular hospital admissions and in-hospital mortality during the COVID pandemic in two successive waves, and to evaluate differences by sex, age, and deprivation index subgroups.
Methods and Results: We obtained acute cardiovascular hospital episodes during the years 2019–2020 from region-wide data on public healthcare usage for the population of Catalonia (North-East Spain). We fitted time models to estimate the incidence rate ratios (IRRs) of the acute coronary syndrome (ACS) and acute heart failure (HF) admissions during the first pandemic wave, the between-waves period, and the second wave compared with the corresponding pre-COVID-19 periods and to test for the interaction with sex, age, and area-based socioeconomic level. We evaluated the effect of COVID-19 period on in-hospital mortality. ACS (n = 8,636) and HF (n = 27,566) episodes were defined using primary diagnostic ICD-10 codes. ACS and HF admissions decreased during the first wave (IRR = 0.66, 95%CI: 0.58–0.76 and IRR = 0.61, 95% CI: 0.55–0.68, respectively) and during the second wave (IRR = 0.80, 95%CI: 0.72–0.88 and IRR = 0.76, 95%CI: 0.69–0.84, respectively); acute HF admissions also decreased in the period between waves (IRR: 0.81, 95%CI: 0.74–0.89). The impact was similar in all sex and socioeconomic subgroups and was higher in older patients with ACS. In-hospital mortality was higher than expected only during the first wave.
Conclusion: During the first wave of the COVID-19 pandemic, there was a marked decline in urgent cardiovascular hospital admissions that were attenuated during the second wave. Both the decline and the attenuation of the effect have been similar in all subgroups regardless of age, sex, or socioeconomic status. In-hospital mortality for ACS and HF episodes increased during the first wave, but not during the second wave.This study was funded with a grant from Sociedad Española de Cardiología y Fundación Española del Corazón (SEC/FEC-INV-CLI 21/017).

Sample size requirement in trials that use the composite endpoint major adverse cardiovascular events (MACE): new insights
Composite endpoints; Correlation; Sample sizePuntos finales compuestos; Correlación; Tamaño de la muestraPunts finals compostos; Correlació, Grandària de la mostraBackground
The real impact of the degree of association (DoA) between endpoint components of a composite endpoint (CE) on sample size requirement (SSR) has not been explored. We estimate the impact of the DoA between death and acute myocardial infarction (AMI) on SSR of trials using use the CE of major adverse cardiac events (MACE).
Methods
A systematic review and quantitative synthesis of trials that include MACE as the primary outcome through search strategies in MEDLINE and EMBASE electronic databases. We limited to articles published in journals indexed in the first quartile of the Cardiac & Cardiovascular Systems category (Journal Citation Reports, 2015–2020). The authors were contacted to estimate the DoA between death and AMI using joint probability and correlation. We analyzed the SSR variation using the DoA estimated from RCTs.
Results
Sixty-three of 134 publications that reported event rates and the therapy effect in all component endpoints were included in the quantitative synthesis. The most frequent combination was death, AMI, and revascularization (n = 20; 31.8%). The correlation between death and AMI, estimated from 5 trials¸ oscillated between − 0.02 and 0.31. SSR varied from 14,602 in the scenario with the strongest correlation to 12,259 in the scenario with the weakest correlation; the relative impact was 16%.
Conclusions
The DoA between death and AMI is highly variable and may lead to a considerable SSR variation in a trial including MACE.Intramural CIBER-ESP PR22 from the Center for Biomedical Research in Epidemiology and Public Health Network (CIBERESP)
Association of renin–angiotensin system blockers with COVID-19 diagnosis and prognosis in patients with hypertension: a population-based study
COVID-19; Angiotensin receptor blockers; HypertensionCOVID-19; Bloqueadores de los receptores de angiotensina; HipertensiónCOVID-19; Bloquejadors dels receptors d'angiotensina; HipertensióBackground
The effect of renin–angiotensin system (RAS) blockade either by angiotensin-converting enzyme inhibitors (ACEis) or angiotensin-receptor blockers (ARBs) on coronavirus disease 2019 (COVID-19) susceptibility, mortality and severity is inadequately described. We examined the association between RAS blockade and COVID-19 diagnosis and prognosis in a large population-based cohort of patients with hypertension (HTN).
Methods
This is a cohort study using regional health records. We identified all individuals aged 18–95 years from 87 healthcare reference areas of the main health provider in Catalonia (Spain), with a history of HTN from primary care records. Data were linked to COVID-19 test results, hospital, pharmacy and mortality records from 1 March 2020 to 14 August 2020. We defined exposure to RAS blockers as the dispensation of ACEi/ARBs during the 3 months before COVID-19 diagnosis or 1 March 2020. Primary outcomes were: COVID-19 infection and severe progression in hospitalized patients with COVID-19 (the composite of need for invasive respiratory support or death). For both outcomes and for each exposure of interest (RAS blockade, ACEi or ARB) we estimated associations in age-, sex-, healthcare area- and propensity score-matched samples.
Results
From a cohort of 1 365 215 inhabitants we identified 305 972 patients with HTN history. Recent use of ACEi/ARBs in patients with HTN was associated with a lower 6-month cumulative incidence of COVID-19 diagnosis {3.78% [95% confidence interval (CI) 3.69–3.86%] versus 4.53% (95% CI 4.40–4.65%); P < 0.001}. In the 12 344 patients with COVID-19 infection, the use of ACEi/ARBs was not associated with a higher risk of hospitalization with need for invasive respiratory support or death [OR = 0.91 (0.71–1.15); P = 0.426].
Conclusions
RAS blockade in patients with HTN is not associated with higher risk of COVID-19 infection or with a worse progression of the disease.The study was partially funded by ‘CIBER de Epidemiología y Salud Pública (CIBERESP)’
