Case report: pseudoaneurysm of left ventricle secondary to infective endocarditis complicated by cardiac rupture-a multimodality imaging approach.

Background: Pseudoaneurysm (PSA) of the left ventricle (LV) is a rare peri-annular complication of infective endocarditis (IE), and it is associated with high risk of free wall rupture. The diagnosis is challenging because the exact incidence and the pathogenesis are still unclear. Case summary: A 69-year-old lady underwent prosthetic mitral valve replacement for IE secondary to Staphylococcus aureus sepsis complicated by multiple embolizations. In the post-operative period, the patient developed persistent low-grade fever with negative blood culture. Transoesophageal echocardiography (TOE) revealed complete posterior valve detachment and a PSA sac arising from the antero-lateral commissure; the colour flow Doppler showed massive mitral regurgitation. Thoracic computed tomography (CT) scan confirmed the echo data and the exact localization of the cardiac rupture. The patient underwent reoperation, a pericardial patch was sutured to exclude the PSA sac, and a mechanical prosthesis valve was finally implanted. A follow-up TOE revealed the exclusion of the PSA; two leakages with mild peri-valvular mitral regurgitation were found, with no haemodynamic impact. Discussion: In our case, the patient developed a PSA of the LV as a consequence of peri-annular extension of IE on the mitral valve. Pseudoaneurysm is a potentially lethal complication, if not promptly treated. Multimodality imaging including echocardiography and CT scan is recommended, in order to plan surgery ad hoc.

Comparative analysis of level of evidence and class of recommendation for 50 clinical practice guidelines released by the European Society of Cardiology from 2011 to 2022.

BACKGROUND: The European Society of Cardiology (ESC) clinical practice guidelines are essential tools for decision-making. AIM: To analyze the level of evidence (LOE) and the class of recommendations in the ESC guidelines released in the last 12 years. METHODS: We evaluated 50 ESC guidelines released from 2011 to 2022, related to 27 topics and categorized them into seven macro-groups. We analyzed every recommendation in terms of LOE and class of recommendation, calculating their relative proportions and changes over time in consecutive editions of the same guideline. RESULTS: A total of 6972 recommendations were found, with an increase in number per year over time. Among the 50 ESC guidelines, the proportional distribution of classes of recommendations was 49% for Class I, 29% for Class IIa, 15% for Class IIb, and 8% for Class III. Overall, 16% of the recommendations were classified as LOE A, 31% LOE B and 53% LOE C. The field of preventive cardiology had the largest proportion of LOE A, while the lowest was in the field of valvular, myocardial, pericardial and pulmonary diseases. The overall proportion of LOE A recommendations in the most recent guidelines compared to their prior versions increased from 17% to 20%. CONCLUSIONS: The recommendations included in the ESC guidelines widely differ in terms of quality of evidence, with only 16% supported by the highest quality of evidence. Although a slight global increase in LOE A recommendations was observed in recent years, further scientific research efforts are needed to increase the quality of evidence.

Digital literacy as a potential barrier to implementation of cardiology tele-visits after COVID-19 pandemic: the INFO-COVID survey.

BACKGROUND: During the COVID-19 pandemic, the implementation of telemedicine has represented a new potential option for outpatient care. The aim of our study was to evaluate digital literacy among cardiology outpatients. METHODS: From March to June 2020, a survey on telehealth among cardiology outpatients was performed. Digital literacy was investigated through six main domains: age; sex; educational level; internet access; availability of internet sources; knowledge and use of teleconference software programs. RESULTS: The study included 1067 patients, median age 70 years, 41.3% females. The majority of the patients (58.0%) had a secondary school degree, but among patients aged ≥ 75 years old the most represented educational level was primary school or none. Overall, for internet access, there was a splitting between "never" (42.1%) and "every day" (41.0%), while only 2.7% answered "at least 1/month" and 14.2% "at least 1/week". In the total population, the most used devices for internet access were smartphones (59.0%), and WhatsApp represented the most used app (57.3%). Internet users were younger compared to non-internet users (63 vs. 78 years old, respectively) and with a higher educational level. Age and educational level were associated with non-use of internet (age-per 10-year increase odds ratio (OR) = 3.07, 95% CI: 2.54-3.71, secondary school OR = 0.18, 95% CI: 0.12-0.26, university OR = 0.05, 95% CI: 0.02-0.10). CONCLUSIONS: Telemedicine represents an appealing option to implement medical practice, and for its development it is important to address the gaps in patients' digital skills, with age and educational level being key factors in this setting.

How did COVID-19 affect medical and cardiology journals? A pandemic in literature.

BACKGROUND AND AIMS: The spreading speed of the COVID-19 pandemic forced the medical community to produce efforts in updating and sharing the evidence about this new disease, trying to preserve the accuracy of the data but at the same time avoiding the potentially harmful delay from discovery to implementation. The aim of our analysis was to assess the impact of the COVID-19 pandemic on medical literature in terms of proportion of COVID-19-related published papers and temporal patterns of publications within a sample of general/internal medicine and cardiology journals. METHODS: We searched through PubMed scientific papers published from 1 January 2020 to 31 January 2021 about COVID-19 in ten major medical journals, of which five were in general/internal medicine and five in the cardiology field. We analyzed the proportion of COVID-19-related papers, and we examined temporal trends in the number of published papers. RESULTS: Overall, the proportion of COVID-19-related papers was 18.5% (1986/10 756). This proportion was higher among the five selected general/internal medicine journals, compared with cardiology journals (23.8% vs 9.5%). The vast majority of papers were not original articles; in particular, in cardiology journals, there were 28% 'original articles', 17% 'review articles' and 55.1% 'miscellaneous', compared with 20.2%, 5.1% and 74.7% in general/internal medicine journals, respectively. CONCLUSIONS: Our analysis highlights the big impact of the COVID-19 pandemic on international scientific literature. General and internal medicine journals were mainly involved, with cardiology journals only at a later time.

Cardioversion of recent-onset atrial fibrillation: current evidence, practical considerations, and controversies in a complex clinical scenario.

Atrial fibrillation (AF) represents the most common arrhythmia and is associated with increased morbidity and mortality generating high social costs. Due to its high prevalence, AF is usually managed not only by cardiologists but also by general practitioners or clinicians in emergency departments. The conventional classification of AF includes "recent­onset AF" defined as an arrhythmia episode shorter than 48 hours. In patients with a definite duration of AF of less than 24 hours and a very low-risk profile (CHA2DS2VASc of 0 in men and 1 in women), the thromboembolic risk seems to be low, and the standard 4­week anticoagulation therapy is now regarded as optional treatment. Cardioversion (electrical or pharmacological) in recent­onset AF represents a valid rhythm control strategy. Electrical cardioversion is usually reserved for hemodynamically unstable patients and performed with biphasic waveform shocks. On the other hand, pharmacological cardioversion is preferred in hemodynamically stable patients. Several antiarrhythmic drugs have been studied so far, but some questions still remain unresolved mainly due to lack of randomized clinical trials and prospective studies. The current guidelines do not uniformly agree on which drug to use for pharmacological cardioversion, and drug preference varies widely in clinical practice. The aim of this narrative review is to sum up and critically evaluate novel evidence regarding recent­onset AF as well as to provide some practical considerations particularly focused on rhythm control with pharmacological cardioversion.
