Abstract
AIMS The current study assessed the impact of COVID-19-related public containment measures (i.e. lockdown) on the ST elevation myocardial infarction (STEMI) epidemic in Belgium. METHODS AND RESULTS Clinical characteristics, reperfusion therapy modalities, COVID-19 status and in-hospital mortality of consecutive STEMI patients who were admitted to Belgian hospitals for percutaneous coronary intervention (PCI) were recorded during a three-week period starting at the beginning of the lockdown period on 13 March 2020. Similar data were collected for the same time period for 2017-2019. An evaluation of air quality revealed a 32% decrease in ambient NO2 concentrations during lockdown (19.5 µg/m³ versus 13.2 µg/m³, p < .001). During the three-week period, there were 188 STEMI patients admitted for PCI during the lockdown versus an average 254 STEMI patients before the lockdown period (incidence rate ratio = 0.74, p = .001). Reperfusion strategy was predominantly primary PCI in both time periods (96% versus 95%). However, there was a significant delay in treatment during the lockdown period, with more late presentations (>12 h after onset of pain) (14% versus 7.6%, p = .04) and with longer door-to-balloon times (median of 45 versus 39 min, p = .02). Although the in-hospital mortality between the two periods was comparable (5.9% versus 6.7%), 5 of the 7 (71%) COVID-19-positive STEMI patients died. CONCLUSION The present study revealed a 26% reduction in STEMI admissions and a delay in treatment of STEMI patients. Less exposure to external STEMI triggers (such as ambient air pollution) and/or reluctance to seek medical care are possible explanations of this observation.

Abstract
COVID-2019 disease mainly affects the respiratory tract and can progress in severe cases to pneumonia, acute respiratory distress syndrome and multi-organ failure. Patients with prior cardiovascular disease are at higher risk of developing an infection and progressing to a severe form of the disease. Also, due to the growing number of infected cases, it is clear that, in addition to the typical respiratory symptoms caused by the infection, some patients suffer from cardiovascular damage. This condition can, in fact, cause significant myocardial damage, which worsens the disease and affects the prognosis. Based on the results of currently published research, it seems important to discuss the manifestations and characteristics of myocardial damage induced by COVID-19 and its impact on patient prognosis.

Abstract
Syncope is a frequent reason for admission to emergency department or consultations. The common pathophysiological mechanism is a drop in systemic blood pressure leading to cerebral hypoperfusion, and ultimately to total loss of consciousness. The causes are multiple, with varying degrees of severity, classified into three main types : reflex syncope, syncope due to orthostatic hypotension and cardiac syncope. Among these, orthostatic hypotension can be easily detected, particularly by performing an orthostatic challenge with active standing, which is recommended in the presence of any syncope. Simple measures can reduce the recurrence of this type of syncope, even if sometimes drug treatments are necessary. In this article, we will detail the characteristics, diagnostic methods and therapies recommended by the latest guidelines of the European Society of Cardiology.

Abstract
The management of complex cardiovascular disease has changed considerably with the development of new care strategies. In cardiology, the «Heart Team» or literally «Equipe du cœur» occupies a prominent place in the latest European and American recommendations, particularly in the management of complex coronary or valvular diseases and in heart failure patients. The concept of «Heart Team» is based on the need for a multidisciplinary holistic approach based on evidence (respect of the recommendations of the scientific societies), the patient as a whole (comorbidities, preferences), risks and long-term benefits of the treatment selected and performed, as well as on the level of local expertise. It aims to determine the best management strategy for the patient, and perhaps to guarantee a better result (prognosis).

Abstract
Coronarography consists in selective angiography of the coronary arteries obtained invasively. It represents the gold standard for the anatomical exploration of the coronary arteries and establishes the first step for the indication of possible percutaneous or surgical revascularisation. According to substantial progress, it represents an essential diagnostic tool frequently used with, despite its invasive characteristic, a very low complication's rate. The present article describes the patient's preparation for this procedure, technical modalities, major indications, contraindications and possible complications.

Abstract
Percutaneous or surgical coronary revascularization must only be realized if myocardial ischemia is clearly demonstrated. In practice, this ischemia is most often seeked by non-invasive tests. These ones are unfortunately not systematically realized or may bring equivocal results compared to angiographic images. Coronary angiography remains the test of choice for the evaluation of coronary disease, but visual analysis of coronary stenosis does not confirm their hemodynamic significance. The measurement of coronary flow reserve by FFR ("fractional flow reserve") or iFR («instantaneous wave-free ratio») is a simple method to invasively assess the hemodynamic impact of a coronary lesion. Spastic angina, when suspected by clinical history, can also be confirmed during coronary angiography by the provocative methylergonovine test.

Abstract
In interventional cardiology, percutaneous transluminal coronary angioplasty (PTCA) definitely represents a revolution in the history of medicine, illustrating the medical community intention to replace aggressive revascularization intervention by less invasive procedure. Rapidly adopted by physicians and patients, its utilization has grown exponentially and in parallel, numerous technical progresses have pushed forward the frontiers of its indications. This article summarizes the principal evolution of this revascularization technique from its beginning until its last innovations, describing some technical characteristics and emphasizing on some changes and extension of its indications.

Abstract
In 40 years of existence, interventional cardiology has witnessed the introduction of numerous tools and techniques that have contributed to the important application's broadening of percutaneous techniques, particulary in anatomical situations previously unfavourable, and which were, at that time, subject to surgical revascularization. Among these hostiles situations, one of the principal consists in failure to adequately dilate the lesions and/or to the inability to deliver and implant a stent appropriately, situations frequently associated with a high rate of procedural complications and poor long-term clinical outcomes. Thanks to the development of complementary dedicated techniques such atherectomy device, the treatment of most fibrotic and heavily calcified lesions has become feasible and safe. The present article describes the rotational atherectomy procedure, its indications and its clinical results.

Abstract
The Micra® leadless pacemaker has demonstrated both safety and efficacy in the short and mid-term as an alternative to conventional transvenous pacemakers. This technology provides a new solution, especially for patients without conventional venous approach and for older patients with atrial fibrillation presenting with symptomatic bradycardia. The advantages of this approach are multiple : a miniature technology therefore less invasive, short procedure, no stimulation leads, or need to create a surgical pocket with a reduced risk of infection. The pacemaker's battery has a life expectancy similar to that of a conventional transvenous pacemaker. In this article, we discuss the characteristics of Micra® versus the traditional transvenous pacemaker.

Abstract
The effects of angiotensin converting enzyme (ACE) inhibitors result from the inhibition of the ACE (kininase II) to ultimately influence both the renin-angiotensin system and the degradation of the bradykinin (BK) metabolism. ACE inhibitors block the degradation of BK and substance P by ACE. In addition, an active metabolite of BK (Des-Arg9-BK) is catalysed by kininase I and its degradation is controlled in part by the conversion enzyme. These molecules have been associated with increased plasma extravasation associated with ACE inhibitors. ACE inhibitors are the leading cause of drug-induced Angioedema (AE). Symptoms of AE mainly occur after the first month of treatment by ACE. However, very late onset cases, sometimes after several years of stable therapy, are also described in the literature. It has been observed that patients previously stable under ACE inhibitor will most likely develop AE soon after the addition of another medication, including the combination of aspirin or non-steroid anti-inflammatory drugs with ACE inhibitor which has proved to be the most common cause, accounting for close to 50% of all AE cases related to ACE inhibitors. This side effect of ACE inhibitors, sometimes very late and rare, deserves to be recalled.

Abstract
Syncope is one of the most common reasons of emergency admission and hospitalisation. Management of syncope remains challenging for the medical staff as there are a multitude of possible etiologies ranging from benign to potentially life-threatening causes. Historically, 30-40% of patients presenting for syncope are hospitalized for further exploration, resulting in a significant cost to health care. The purpose of this article is to clarify the etiologies of syncope and to stratify their risk for a better managment.

Abstract
INTRODUCTION Despite an incidence of about 18-52% of the patients undergoing coronary angiography, chronic total occlusions (CTO) are rarely revascularised by percutaneous angioplasty (PCI). Nevertheless, current evidence suggests that successful CTO angioplasty improves symptoms, quality of life and long-term survival. During the last decade, the improvement of specific tools and techniques for these complex procedures, and the increasing experience of operators, have led to the achievement of success and complication rates almost equivalent to non-CTO angioplasty. Areas covered: This review focuses on the clinical benefits of CTO revascularization and on appropriate patient selection. Expert commentary: Current evidence suggests that successful CTO-PCI improves symptoms, quality of life and long-term survival. During the last years, the improvement of specific techniques for these complex procedures and the increasing experience of operators, have led to the achievement of success and complication rates almost equivalent to non-CTO lesion angioplasty.

Abstract
A routine assay based on the PCR was developed for the detection of Enterocytozoon bieneusi and Encephalitozoon intestinalis in fecal samples. Two oligonucleotide primer pairs from a conserved region in the small-subunit rRNA genes of E. bieneusi (primer pair V1 and EB450) and E. intestinalis (primer pair V1 and SI500) were used to amplify microsporidian DNA. We achieved specific amplification of a 382-bp DNA fragment in E. intestinalis and a 353-bp DNA fragment in E. bieneusi. Boiling of the samples appeared to be most effective for DNA extraction. Fecal samples containing fewer than 10 microsporidia gave a positive result in the PCR assay. Fecal specimens from 30 human immunodeficiency virus-infected patients with microsporidiosis and fecal specimens from 42 patients suspected of having microsporidiosis were investigated by the PCR assay. The PCR assay was validated against standard staining methods (the Uvitex 2B and Chromotrope 2R staining methods) and immunofluorescence assay specific for E. intestinalis. This comparative study has shown that PCR improved species determination and can thus be considered a fast and reliable method for the detection and identification of each intestinal species.

Abstract
Ten years ago, because of the increasing number of patients recovering from Hodgkin disease, some authors advocated systematic laparotomy with splenectomy for more accurate staging in order to adjust therapy with more precision. This attitude now seems questionable because of the occurence of several complications, particularly of life-threatening infections, which can be fatal even after recovery from Hodgkin disease. The case of a twenty-three-year-old male patient with Hodgkin disease stage III A, histological grade I, is reported. MOPP chemotherapy, splenectomy and cobalt radiotherapy were followed by complete recovery. Seven years later the patient died from fulminant pneumococcal meningitis. A review of previously published cases show that prolonged prophylaxis with oral penicillin is mandatory in splenectomized patients. Immunization with the pneumococcal polysaccharide vaccine should be attempted even though the long-term results are still unknown.
