[Coronary ectasias and thrombosis]. / Ectasies coronaires et thrombus.

Ectasias and coronary aneurysms are uncommon coronary artery diseases, can coexist and are poorly known. Their principal etiology in adults is coronary atherosclerosis. It has been suggested that these abnormalities would have poor prognosis and that slow flow could lead to in situ thrombosis and distal embolisation. However, ectasias and aneurysms are most often associated with coronary stenosis. We report a series of 47 cases of ectasias and coronary aneurysms with evaluation of the clinical and angiographic characteristics, the therapeutic choices and we review the literature concerning these lesions. In situ thrombosis does not seem to be the usual pathophysiological mechanism. We retain that this is a particular form of coronary atherosclerosis in this population and present technical problems in case of revascularization with an predominant indication of medical treatment (57.4 % of the cases), but rarely the introduction of anticoagulants (4.25 % of the cases), except in acute coronary syndromes where revascularization is most common (70.6 % of cases) as is usually expected in the general population. The complex angiographic presentation of these lesions is probably an explanation for the low numbers of revascularizations performed.

[Difficulty in diagnosis of a cardiogenic shock with thrombotic and sub-occluded LAD. A train can hide another one!] / Difficulté diagnostic d'un choc cardiogénique sur une sub-occlusion thrombotique de l'IVA. Un train peut en cacher un autre !

The pheochromocytome is a localized tumor at the level of the medullosurrenale in 85% of the cases. The clinical presentation is very variable. Severe Heart failure presentation can be the mode of revelation in 2% of the cases. We present the case of a patient admitted for refractory cardiogenic shock correlated to pheochromocytome tumor. The difficulty of this rare clinical presentation was to confirm rapidly and in emergency this diagnosis in the same time when the patient presents a persistante and severe cardiogenic chock after finding a sub-occluded and thrombotic LAD coronary artery and which was treated by thrombectomy and coronary revascularization. The surgical treatment of this tumor is considered to be a quickly saving treatment. It allows a fast recovery of the cardiac function.

[Ischemic stroke related to spontaneous]. / Accident vasculaire cérébral ischémique en rapport avec hématome coronaire spontané.

Cardiovascular disease in women is a particularly complex pathology especially in the youngest population. The clinical presentation of acute coronary syndromes is sometimes misleading and does not necessarily point to the potential presence of cardiac disease given the frequent absence of cardiovascular risks. Such complexity results in delayed diagnosis, which worsens the outcome of myocardial infarction and generates complications related to the absence of coronary revascularization. We report the case of a patient who suffered an (undiagnosed) apical myocardial infarction that went undetected and was complicated by a voluminous intraventricular thrombus with embolus migration in the cerebral circulation resulting in an ischemic accident. The combination of these two pathologies make their therapeutic management particularly difficult. As widely reported in the literature, the outcome of myocardial infarction in women is poorer than in their male counterparts for a number of reasons. We can assume that in the youngest patients, another physiopathological mechanism is often involved, namely, the occurrence of hematoma and spontaneous coronary dissection. Diagnosis is often difficult even with coronary angiography diagnosis. As shown in the case reported here, initial examination results, if not thoroughly analyzed, may be erroneously interpreted as normal. It is also likely that the presence of hematoma or coronary wall dissection without any plaque rupture may negatively influence the outcome owing to the implementation of inappropriate treatments. In conclusion, in patients presenting with an ischemic cerebral accident, meticulous cardiac examination must be performed even in young women with no cardiovascular risk factors given that the occurrence of hematoma or coronary dissection may contribute to the formation of mural thrombi in the setting of myocardial infarction. Cardiac MRI seems to be particularly effective in the diagnosis of myocardial infarction complicated by the presence of intracavitary thrombi.

[Transfemoral TAVI procedure in women: Minimally-invasive technique]. / Procédure de TAVI par voie fémorale chez la femme : technique minimaliste.

Demographic data point to a substantial proportion of women in the population of elderly patients with an increasing prevalence of aortic stenosis. Implantation of an aortic bioprosthesis via an endovascular approach known as Transcatheter aortic valve implantation (TAVI) in patients presenting with a symptomatic tight aortic stenosis (severe aortic stenosis) (AS) is an alternative therapeutic option to surgical aortic valve replacement in patients at high surgical risk or ineligible for surgery. The literature has shown that this technique seems to be particularly beneficial in female patients. In the Partner A trial, the 1-year mortality rate was significantly lower in women compared to their male counterparts. Other data revealed that although women have a higher risk of experiencing periprocedural complications (vascular events, bleeding and stroke), their outcome is good and often better than that of men. These results are continuously improving thanks to the enhancement of techniques and devices. In view of the published reports reflecting the increasing experience of the teams, it clearly appears that the simplification of TAVI procedures has resulted in improved outcomes. We report here the case of a patient treated by means of a "minimalist" approach to TAVI allowing a reduction of the risks inherent in the procedure. This simplified strategy relies on an optimal use of CT scan findings prior to TAVI. The procedure is carried out under local anesthesia and the main access site is sutured percutaneously (Proglides). The radial artery is used as a secondary access site. Contrast medium is diluted and stimulation is administered via the intraventricular guidewire. Direct stenting is performed when deemed feasible on the basis of CT scan results. Simplified procedures such as these contribute to the improvement of TAVI outcomes. However, further studies focusing on female patients are warranted in order to corroborate these findings.

[Is coronary artery spasm a disease specific to women?] / Spasme coronaire, une pathologie de la femme ?

Vasospastic angina is considered rare in Europe but with a prevalence probably underestimated and affects preferentially men in published studies, mostly involving Asian populations. Vasospastic angina in the female population have specificities in terms of pathophysiology, clinical presentation and prognosis, as well as diagnostic strategies currently recommended, that we describe from a clinical case. Although known for over 50years, vasospastic angina remains a disease still insufficiently researched, probably even less in women. This form of angina must not however be forgotten, and the appropriate diagnostic strategy must be known and used to improve prognosis.
