Mes ennemis, les facteurs de risque My enemies, the risk factors.

We have to distinguish between non-modifiable risk factors such as age, gender, heredity, (we cannot fight against these enemies), and modifiable risk factors (avoidable) such as hypertension, smoking, diabetes, and dyslipidemia. Environmental factors, bad diet, sedentary lifestyle, and smoking are the basis of these risk factors. Cardiovascular disease due to these risk factors is clinically silent during a given period, then symptoms occur which can eventually lead to death. Nine risk factors explain the occurrence of 90 % of myocardial infarctions (MI), their correction avoid 80 % of MI. Despite the presence of several studies proving that secondary prevention reduces coronary mortality, the management of cardiovascular risk factors is not optimal.

[Medico-legal implications of infections during interventionnal cardiology procedure]. / Conséquences médico-légales des infections en cardiologie interventionnelle.

Nosocomial infections in interventional cardiology are rare, but their extreme severity is responsible for medico-legal issues. By the will of the legislator, it should be understood that, as soon as the nosocomial nature of an infection has been recognized, the victims will almost systematically obtain compensation. The payer will be determined by the level of seriousness of the infection and the existence or not of a possible fault. To avoid a conviction, the care teams must compel themselves to respect the recommendations of the professional societies, but also to ensure a perfect traceability of the prophylactic measures. Particular attention must be paid to the management of the vascular approach. Finally, it is essential to inform patients and all those involved in the healthcare chain of the need to get in touch with the intervention team if suspicious signs of an infection appear, to allow for specialized cares.

[TAVI in women, very encouraging results]. / TAVI chez les femmes, des résultats très encourageants.

The population of elderly patients comprises a high percentage of women. This population is more vulnerable due to the presence of numerous comorbidities and is, therefore, particularly exposed to the risk of aortic valve degeneration, resulting in aortic valve stenosis whose symptoms are predictors of poor short-term outcomes. In the presence of symptomatic aortic stenosis, the recommended therapeutic option in this vulnerable population is the implementation of transcatheter aortic valve implantation, preferably via the femoral route. The outcomes of this procedure are better in women than in men despite a more frequent occurrence of vascular, bleeding and cerebral complications. Several hypotheses have been reported in the literature regarding the reasons for such differences. Among other reasons, it is likely that in female patients, the myocardium adjusts better to the occurrence of aortic stenosis and that recovery after valve treatment is also more optimal. Another explanation is the higher frequency of coronary artery disease in this older population. This has a considerable impact on the outcome even when coronary lesions are treated prior to valve implantation. There is still room for improvement and progress can be achieved by further reducing the size of the equipment used in order to decrease the diameter of the vascular access, and by continuing to simplify TAVI procedures. Less invasive techniques should result in decreased complication rates. In addition, dedicated studies should allow us to further improve our practice in this growing population of vulnerable patients.

[Vasospastic angina: An under-diagnosed pathology]. / L'angor spastique : une pathologie sous-diagnostiquée.

The clinical and physiopathological clinical entity known as spastic angina or variant angina has been long documented. It remains, however, an under-estimated condition, which is insufficiently diagnosed and explored. This pathology is associated with severe complications such as heart rhythm disorders, which may potentially result in ventricular fibrillation and cause sudden death. In Japan, this condition occurs more frequently and is better documented. Stimulation tests are also carried out more often and have a higher positivity rate than in France where vasospastic angina is less frequently reported and where provocation tests are associated with negative results and are, consequently, performed less often. In order to improve the detection of this pathology, its potential presence should be explored in patients with rest angina who experience chest pain in the second half of the night and also in instances of acute coronary syndrome with sudden death and no angiographically visible coronary artery disease. The diagnosis should be confirmed by means of ergonovine provocation tests. In order to enhance the sensitivity of these tests without increasing the risk of complications, injection of ergonovine should be preferably carried out via the intracoronary route. By increasing the frequency and sensitivity of these tests, this pathology, which responds well to medical treatment in many cases, could be amenable to therapeutic management as any other form of coronary artery disease.

[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.
