Iatrogenic coronary dissections are rare but potentially serious. Their management is complex, particularly if the dissection occurs without an angioplasty guide in the arterial lumen. In this context, angiography alone is insufficient, and endocoronary imaging is essential (using optical coherence or IVUS) to guide angioplasty when necessary (guide in the true lumen, coverage of the tear). We report here the case of an iatrogenic dissection of the right coronary artery treated with OFDI guiding., Competing Interests: Conflit d'intérêts Consulting et proctoring pour TERUMO., (Copyright © 2024 Elsevier Masson SAS.

The French PCI Registry collects up to 150 clinical, procedural, and one-year follow-up data on all coronary angiographies and angioplasties performed in the 61 participating centers in September 2023. Thanks to the support of the GACI, the DGOS, the ARS, and numerous hospitals, the registry is continuing to expand its coverage across the entire territory, with 90 centers expected to participate in 2024, accounting for nearly half of the French centers. The high quality of this data has already led to the publication of 18 studies in international journals, and around twenty others are currently being written. The online publication of comprehensive and comparative annual reports, along with the implementation of quality indicators to assess practices, would enhance the performance of all participating centers and ultimately benefit our coronary patients., Competing Interests: Déclaration de liens d'intérêts None, (Copyright © 2023 Elsevier Masson SAS.

Aim: Spontaneous coronary artery dissection (SCAD) is a form of acute coronary syndrome (ACS). The aim of this registry is to assess the clinical and angiographic features of SCAD, to describe the therapeutic management and prognosis, and to identify links with other vascular diseases., Method: From 2016 to 2018, 424 patients with a diagnosis of SCAD were included prospectively and retrospectively in 51 French cardiology centres., Results: 373 patients with confirmed SCAD were included. The mean age was 51.5±10.3 years with 90.6% women. 54.7% of patients had <2 cardiovascular risk factors. ACS occurred in 96.2% of patients. 84.2% of patients were managed conservatively, 15.5% interventionally and 0.3% surgically. At 1-year follow-up, recurrence of SCAD occurred in 3.3%. No deaths occurred. The association with fibro-muscular dysplasia was found in 45% of cases and genetic analysis confirmed a strong relationship between the occurrence of SCAD and gene variations at the PHACTR1 locus., Conclusion: The DISCO registry is the largest European cohort of SCAD. It confirms that this disease mainly affects young women with few cardiovascular risk factors, and that there is a strong association with the presence of fibromuscular dysplasia (45%). Conservative management should be preferred, with a favourable prognosis (no deaths at 1 year; recurrence rate of 3.3%)., (Copyright © 2023 Elsevier Masson SAS. All rights reserved.)

The interest in revascularization of chronic total occlusions (CTO) of the coronary arteries during the last decade has not waned. It is one of the latest challenges for percutaneous coronary interventions (PCI), requiring a specific organization of the patient pathway, dedicated equipment, and targeted medical expertise, now establishing CTO as a new discipline in interventional cardiology. Despite technical progress, the success rate of CTO-PCI is still lower than that of non-CTO-PCI, mainly due to guidewire failure. What can be the place of IVUS in CTO recanalization? IVUS offers a real-time cross-sectional image of the lumen and the vessel wall and meets all the criteria for assisting guidewire crossing. In addition, and as in any angioplasty of long and calcified complex lesions, IVUS participates in an optimal sizing of the stent and ensures its proper expansion. Optical coherence tomography (OCT) has no place, for multiple reasons, in the management of a CTO procedure but can help on remote control to ensure an optimal result, to validate the interest of a technique. Endocoronary imaging in CTO as in other complex situations is likely to optimize procedural results, to validate strategic options with the ultimate goal of improving clinical results., Competing Interests: Liens d'intérêt P.Motreff consulting Abott, Boston, Terumo J.Brunet consulting Philips, Terumo., (Copyright © 2022.

Goal: The aim of the study is to assess the incidence, risk factors and prognosis of definite stent thrombosis (ST) at 1 year in the France PCI multicenter prospective registry., Patients and Methods: Only patients who underwent coronary angioplasty with at least one stent implantation between 1 st January 2014 and 31 December 2019 were included. The population was separated into 2 groups: the "ST" group with stent thrombosis and the "control" group without stent thrombosis., Results: 35,435 patients were included. 256 patients (0.72%) presented a ST at 1 year. The rate of ST decreased significantly in acute coronary syndrome (1.5% in 2014 vs. 0.73% in 2019; p = 0.05) but not in chronic coronary syndrome (0.46% in 2014 vs 0.40%; p = 0.98). The risk factors are young age (65.8 years vs 68.2; p = 0.002), clinical context (35.27% vs 16.68%; p = 0.0001), diabetes (35.2 % vs 26.4%; p = 0.002), renal failure (11.7% vs 8%; p = 0.009) and history of coronary angioplasty (28.63% vs 21.86%; p = 0.009) and peripheral arterial disease (14.5% vs 10.1%; p = 0.021), LV dysfunction (37% vs 27.5%; p = 0.003), mean length (39.6 mm vs 31, 7mm; p <0.0001) and the mean number of stents per procedure (1.9 vs 1.6; p <0.0001), a TIMI flow ≤1 pre procedure (21.5% vs 12.4%; p <0.0001) and an intrastent restenosis (11% vs 6%; p <0.0001). The 1-year mortality of the ST group was significantly higher than that of the control group (19.14% vs 5.82%; p <0.0001)., Conclusion: Since 2014, the incidence of ST at 1 year has been decreasing but remains stuck at a floor level of 0.54% in 2019. The battle for ST seems to have been partly won and its risk factors well identified, but its mortality is still high., (Copyright © 2021 Elsevier Masson SAS. All rights reserved.)

Coronary angiography has been a long-standing friend since the first selective injection by Sones in 1958. More than 400,000 coronary angiographies are performed each year in France for the diagnosis and treatment of ischemic heart disease. In just over 60 years, examinations have become simpler, with imaging that has considerably progressed. Nevertheless, it remains an invasive and radiating examination and requires an injection of a potentially nephrotoxic contrast medium. It is a two-dimensional projection of a luminogram of small arteries, in perpetual movement. The technical realization must be perfect, the analysis of the images must be careful. It is important to be aware of the pitfalls and limitations of the examination, and to rely on complementary techniques to resolve ambiguities, whether functional (FFR, IMR) or morphological (IVUS, OCT). Although non-invasive explorations, such as coroscanner, are in full development, these alternative methods have other limitations (lack of resolution, artifacts related to calcifications) which mean that angiography often remains essential for the diagnosis of coronary artery disease, indispensable for deciding on treatment and guiding revascularization. All of these elements make coronary angiography the definition of a friend: someone you know well... but you love anyway., Competing Interests: Déclaration de liens d'intérêts L'auteur déclare ne pas avoir de liens d'intérêts avec cette présentation., (Copyright © 2021 Elsevier Masson SAS.

The COVID-19 pandemic had an unexpected impact on cardiovascular emergencies, particularly STEMI. The France PCI registry and other studies around the world have highlighted a significant decrease in myocardial infarctions arriving at hospital. This decrease is mainly related to patients' fear of coming to the hospital and being contaminated. Although the STEMI revascularisation time targets (<120min) are often difficult to achieve in normal times, they were almost impossible to achieve in periods of lockdown because of the many obstacles. Longer delays and longer total ischemic time have led to excess mortality, especially in the regions most affected by the epidemic. Recommendations for the management of STEMI during the COVID-19 period have thus been issued by the scientific societies. STEMI in patients with COVID-19 often have an uncommon clinical presentation, and the absence of coronary obstruction on angiography is frequent. Their prognosis is very poor. Only public information campaigns and an organisation adapted to the management of coronary emergencies during epidemics can try to limit their effects and avoid aggravating an already fragile health situation in the future., (Copyright © 2020 Elsevier Masson SAS.

Transcatheter aortic valve implantation (TAVI) has become the major approach to manage the severe aortic stenosis in inoperable patients that frequently present a coronary artery disease. To date, the available data related to the impact of these coronary lesions on survival is conflicting. When indicated, coronary revascularization could be beneficial for proximal lesions when performed before or during TAVI. The per-procedure coronary artery occlusion is rare, but with a bad prognosis. The coronary occlusion is more frequent with short distance of the coronary implantation and the small aortic sinuses, mostly occurring in the left main coronary. The scan analysis to identify high-risk cases is therefore important before the procedure in order to anticipate and prevent complications by specific techniques. Recently, late occlusion cases have been described and linked to thrombus or fibrosis mechanisms. The rate of success of percutaneous coronary intervention (PCI) after TAVI approach is weak, because of the difficulties of selective catheterization due to the stent of prosthesis. The different techniques of PCI have been outlined according to the type of the prosthesis., (Copyright © 2019 Elsevier Masson SAS. All rights reserved.)

Regular physical exercice has undeniable cardiovascular benefits and improves life expectancy. This benefice seems limited to moderate intensity exercises. Intense and chronic physical exercice would lead to heart structural changes. For a long time, knowledge of these cardiac effects seemed limited to the left ventricle. Since more authors have shown that right ventricle is vulnerability to the effects of intense chronic training. We report a Gallavardin-type ventricular stress tachycardia in a young with healthy hearted; in whom a right infundibular arrhythmogenic focus has been found in the absence of structural alteration of the right ventricle. Intense athletic activity may reveal a latent arrhythmogenic focus through sympathetic activation. Ablation was the preferred therapeutic strategy, preferred to drug therapy and derived from an analysis of risk-benefit ratios., (Copyright © 2018 Elsevier Masson SAS. All rights reserved.)

Purpose: To compare the clinical, angiographic, therapeutic and prognostic characteristics of nonagenarians presenting with non-ST elevation acute coronary syndrome with those of patients under 90 years of age., Methods: We used the CRAC register database including 6 catheterization laboratories in the Center Val-de-Loire region. Only patients with positive-troponin non-ST elevation ACS included in the registry from 2014 to 2017 were selected for epidemiological and procedural data. Regarding antiplatelet therapy, hospital and one-year follow-up data, only patients in the 2014-2015 period were analyzed., Results: From January 1st, 2014 to December 31st, 2017, 5.964 patients with a positive-troponin non-ST ACS, including 133 nonagenarians (2.2%) were included in the CRAC registry. Arterial hypertension and the history of coronary angioplasty were more common among nonagenarians. They present more multivessel and left main disease. The use of the bare metal stent was predominant in 2014-2015 and then became marginal in 2016-2017. Clopidogrel was the most widely used anti platelet and more than one in two nonagenarians remain on dual therapy after 12 months. One-year stroke and hospital and one-year mortality were higher in this age group., Conclusions: Nonagenarians with a positive-troponin non-ST elevation ACS have more severe coronary artery disease and a poorer prognosis than those younger than 90 years of age., (Copyright © 2018 Elsevier Masson SAS.

Aortic stenosis is a frequent disease in the elderly. Its prevalence is 0.4% with a sharp increase after the age of 65, and its outcome is very poor when the patient becomes symptomatic. The interventional procedure known as TAVI (trans-catheter aortic valve implantation), which was developed in France and carried out for the first time in Rouen by Prof. Alain Cribier and his team in 2002, has proven to be a valid alternative to surgical aortic valve replacement. At first, this technique was shown to be efficient in patients with contra-indications to surgical treatment or deemed to be at high surgical risk. Given the very promising outcomes achieved as a result of close heart team collaboration, appropriate patient selection, simplified procedures and reduced complication rates, transfemoral (TF) TAVI is now preferred in symptomatic intermediate risk patients>75 years old according to the latest ESC guidelines. In 2017, in France, TAVI is currently performed in 50 centers with on-site cardiac surgery. The 2016 TAVI outcomes recorded in the French national TAVI registry (France TAVI) are very encouraging and show that for 7133 patients treated (age 83.4±7 years, logistic Euroscore 14%), 87% of whom via the TF approach, cross-over to surgery was very low (0.5%) with a 3.0% in-hospital mortality rate. The substantial increase in TAVI indications and the improvement of its outcomes may in the near future call for a reconsideration of the number of high volume centers authorized to carry out this technique., (Copyright © 2018.

Spontaneous coronary artery dissection (SCAD) is a poorly understood and under-diagnosed entity of acute coronary syndrome, affecting predominantly young women. Relatively large series have been published in the past five years highlighting this condition, once believed to be rare. Indeed, the pathophysiology, natural history, clinical presentation, patient profile, diagnostic modalities, management and outcomes of SCAD are becoming better understood. The aim of our review is to provide a brief "state of the art" of SCAD in 2016 to help the clinician in the management of this challenging condition., (Copyright © 2016. Published by Elsevier SAS.)

Spontaneous coronary artery dissection (SCAD) is a poorly understood and under-diagnosed entity of acute coronary syndrome, affecting predominantly young women. On coronary angiography, the diagnosis remains challenging, particularly in case of intramural hematoma without intimal rupture. Intracoronary imaging, especially by optical coherence tomography (OCT), provides an incremental value in terms of diagnosis and management. We report the case of a 49-year-old woman admitted for STEMI caused by an intramural hematoma. In the discussion part, we aim to review the epidemiology, physiopathology, diagnosis, management and long-term prognosis of SCAD., (Copyright © 2015 Elsevier Masson SAS. All rights reserved.)

The outcome of patients with ST elevation acute coronary syndrome (ACS) has been increasingly improving in the general population over the past few decades. However, detailed analysis of the results show that the reduction in mortality rates is higher in males compared to their female counterparts. The excess mortality rate observed in women, though sometimes questioned, has been widely reported in the literature. The higher mortality rate observed in women with ST elevation ACS can be explained by the presence of aggravating clinical factors such as older age, a higher percentage of diabetics, and a higher frequency of cardiogenic shock. Other factors pertaining to patient management seem to negatively impact the outcome. These factors include a lower use of reperfusion strategies, longer time to treatment mainly as a result of diagnostic uncertainty with respect to a disease, which is believed to affect principally the male gender. The doubts that female patients themselves and their families have about the nature of their symptoms are also present in the medical environment but cease to exist in the catheterization laboratory. This is illustrated in the first clinical case that we present here. Coronary reperfusion is the cornerstone of the therapeutic management of MI. In this context, bleeding complications associated with the implemented treatments can also result in an increased mortality rate in this more vulnerable population. When all the factors likely to influence the prognosis are taken into account, excess mortality seems to persist in women, especially in younger patients. As described in the second clinical case, a distinct physio-pathological factor, more frequent in women, could account for this higher mortality rate. Indeed, spontaneous coronary dissection and intramural hematoma are not always easy to diagnose and may not be adequately managed by reperfusion treatments. In addition, these coronary reperfusion strategies are probably not adapted to this type of ACS. It is, therefore, very important to identify them by angiography coupled with intra-coronary imaging examination when necessary and to carry out further research to adjust our PCI techniques to this pathology., (Copyright © 2015 Elsevier Masson SAS.

Data on regional variations in the characteristics, management and early outcome of patients admitted with ST-elevation myocardial infarction (STEMI) in France are limited. We used data from the FAST-MI 2010 registry to determine whether regional specificities existed, dividing the French territory into 6 larger geographical regions. Variations in the patients' characteristics were found, partly related to regional variations in demography. Acute reperfusion strategy showed more use of primary percutaneous coronary intervention in the greater Paris area, compared to other regions, which would be expected owing to geography and local availability of catheterization laboratories. Overall, however, in-hospital management showed more similarities than differences across regions. Complications, and in particular in-hospital mortality, did not differ significantly among regions., (Copyright © 2015. Published by Elsevier SAS.)

We report the case of a 24-year-old patient admitted for anterior ST segment elevation myocardial complicated by ventricular fibrillation and revealing thrombotic sub occlusion of the left anterior descending coronary artery. Revascularization is achieved by manual thrombectomy and use of Glycoprotein GPIIbIIIa inhibitors and permits to restore TIMI 3 flow. Given the large thrombotic burden, the patient is initially treated medically (optimal anti thrombotic therapy without stenting) and benefits from angiographic control 48 hours later with imaging by Optical Coherence Tomography (OCT). It shows a reduction of thrombus burden and lack of significant underlying organic lesion (no organic stenosis or plaque rupture). In view of these data, it was decided to continue medical treatment alone without stenting. OCT imaging at 6 months shows atheroma without stenosis, thrombus or plaque rupture. This young patient remains asymptomatic and recovered normal left ventricular function with a 2-year follow-up., (Copyright © 2014 Elsevier Masson SAS. All rights reserved.)
