RESUMEN
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.

OBJECTIVES: To assess the reliability and low cost of a computerized interventional cardiology (IC) registry to prospectively and systematically collect high-quality data for all consecutive coronary patients referred for coronary angiogram or/and coronary angioplasty. BACKGROUND: Rigorous clinical practice assessment is a key factor to improve prognosis in IC. A prospective and permanent registry could achieve this goal but, presumably, at high cost and low level of data quality. One multicentric IC registry (CRAC registry), fully integrated to usual coronary activity report software, started in the centre Val-de-Loire (CVL) French region in 2014. METHODS: Quality assessment of CRAC registry was conducted on five IC CathLab of the CVL region, from January 1st to December 31st 2014. Quality of collected data was evaluated by measuring procedure exhaustivity (comparing with data from hospital information system), data completeness (quality controls) and data consistency (by checking complete medical charts as gold standard). Cost per procedure (global registry operating cost/number of collected procedures) was also estimated. RESULTS: CRAC model provided a high-quality level with 98.2% procedure completeness, 99.6% data completeness and 89% data consistency. The operating cost per procedure was 14.70 ($16.51) for data collection and quality control, including ST-segment elevation myocardial infarction (STEMI) preadmission information and one-year follow-up after angioplasty. CONCLUSIONS: This integrated computerized IC registry led to the construction of an exhaustive, reliable and costless database, including all coronary patients entering in participating IC centers in the CVL region. This solution will be developed in other French regions, setting up a national IC database for coronary patients in 2020: France PCI.

Ionic Flash NanoPrecipitation (iFNP) was evaluated as a novel method for the synthesis of inorganic-organic hybrid nanomaterials and proved to be remarkably effective, fast and practical. To prove the potential of iFNP, various nanostructured GdPO4-based materials of biomedical imaging relevance were easily prepared in a one-step, tunable and highly controlled manner using only water as solvent.
RESUMEN
Iatrogenic acute dissection of the ascending aorta following coronary angiography and percutaneous intervention is rare. The options for treatment are dictated by patient stability, nature of dissection of the coronary vessel, ability to restore the coronary circulation and extent of aortic dissection. Usually localized aortic dissections have been managed conservatively or treated by sealing the entry with a coronary stent. Extensive dissections may require a surgical intervention. We report the case of a 52-year-old man with iatrogenic dissection of the right coronary artery ostium and extension of the dissection to the ascending aorta during intraluminal angioplasty of an obstructive lesion in the first portion of the right coronary artery. The patient was managed conservatively without stenting (failure stenting of the right coronary artery) and without surgery. Aortic dissection was monitored by means of transesophageal echocardiography. Serial computed tomography scans demonstrated spontaneous resolution of the dissection. The evolution of the patient was satisfactory. Causes, frequency and treatment procedures of this iatrogeny are discussed.

MRI has acquired over the years a role in the evaluation of cardiovascular pathology especially with regards to its ability to assess right and left ventricular function and delayed postcontrast "viability" sequences. Current class I clinical indications include: viability for patients with ischemic cardiomyopathy and acute coronary syndrome, etiology and prognostic evaluation of non-ischemic cardiomyopathies including myocarditis and arrhytmogenic right ventricular cardiomyopathy, chronic pericarditis and cardiac masses, non-urgent aortic aneurysm and dissection, congenital cardiopathies: vascular malformations and follow-up after curative or palliative surgery. MRI provides a complete non operator dependent evaluation, and is particularly useful for follow-up since it may be repeated due to its absence of ionizing radiation

We describe here the MRI surveillance of septal alcohol ablation in a case of symptomatic obstructive cardiomyopathy. MRI examinations were performed before, 15 days and 2 months after alcohol ablation using an identical protocol to study the function, regional perfusion and the equilibrium perfusion in order to directly visualize the infarction. MRI seems to be an excellent investigation in the surveillance of such patients, allowing precise quantification of the infarcted zone. The various stages of cellular necrosis in the induced infarct were demonstrated, and the role of remodelling in increasing the functional area of the systolic ejection pathway.

Vitis vinifera red berries are characterized by anthocyanins whose chemical structures are among the simplest encountered in higher plants. On the contrary, many plants, including orchids, petunias, red cabbage, elderberries, potatoes for instance, have developed very complicated anthocyanins featuring side-chains at the available positions of the aglycone skeleton. Such pigments were shown to possess bio-physico-chemical properties not to be seen with the grape common anthocyanins. Among beverages (water, tea, beer, wine, coffee, juices, milk), red wine is the only one whose organoleptic properties improve with time and this is called ageing. The grape/fresh red wine pigments, after a few months, disappear from the wine giving birth to new pigments resulting from the wine spontaneous chemistry allowing it to remain red for many years. What are the wine pigments and why are they so stable is the purpose of this mini-review. The structural simplicity of grape anthocyanins and the long lasting colour of red wine is another French paradox; we call it French paradox II.

The aim of this retrospective study was to assess the immediate and medium-term clinical and angiographic results of multiple angioplasty with stenting in 100 consecutive patients with multivessel coronary artery disease. The mean age of the population was 62 +/- 11 years. Two hundred and eight lesions were treated (2.5 +/- 0.7 per patient) with implantation of 1.14 +/- 0.4 stents per lesion. The angiographic success rate was 98.7%. There were 5 major complications in the hospital period: 3 deaths, including 2 of cardiac causes, one coronary bypass procedure and one Q wave myocardial infarction. During follow-up (17 +/- 6 months), eight patients died (5 of cardiac causes) and secondary revascularisation procedures were required in 22 patients. At 6 months, the angiographic restenosis rate was 32% per lesion, 28.8% per stent and 33 patients had at least one restenosis.
