Calcified aortic valve stenosis is the most frequent valvular heart disease in developed countries with a very poor outcome when symptoms develop. However, several of these patients are denied for surgery. The main reasons are their advanced age (elderly patient), co-morbidities, technical limitations and a very high surgical risk. It is currently possible to propose a Transcatheter Aortic Valve Implantation (TAVI). After selection of candidates, the feasibility of the intervention is analysed. The size of the aortic bioprosthesis must be selected according to the cardiac anatomy. Several cardiac imaging modalities (echocardiography, computed tomography and cardiac MRI) can be used to identify unsuitable situations. Heavy calcifications or tortuosity can thwart the retrograde approach use. The sub-clavian arteries (for the CoreValve) and trans-apical approach (for the Edwards-Sapien) constitute alternatives ways. [less ▲]Detailed reference viewed: 19 (2 ULg)

Cardiac toxicity is one of the most concerning side effects of anti-cancer therapy. The gain in life expectancy obtained with anti-cancer therapy can be compromised by increased morbidity and mortality associated with its cardiac complications. While radiosensitivity of the heart was initially recognized only in the early 1970s, the heart is regarded in the current era as one of the most critical dose-limiting organs in radiotherapy. Several clinical studies have identified adverse clinical consequences of radiation-induced heart disease (RIHD) on the outcome of long-term cancer survivors. A comprehensive review of potential cardiac complications related to radiotherapy is warranted. An evidence-based review of several imaging approaches used to detect, evaluate, and monitor RIHD is discussed. Recommendations for the early identification and monitoring of cardiovascular complications of radiotherapy by cardiac imaging are also proposed. [less ▲]Detailed reference viewed: 23 (3 ULg)

In the last years, the management of left valvular disease has considerably evolved. The American guidelines of 1998 were recently reviewed. Since this year, we have European guidelines which are different in some points. The place of exercise testing in risk stratification of asymptomatic valvular disease is increasing and helps to make earlier decision regarding the need for surgery.

Objectives - The recent newer advances in computed tomography have dramatically changed our approach to imaging cardiac disease. This study sought to compare the diagnostic value of 16-multi-detector spiral computed tomography (MSCT) for detecting coronary artery stenosis. Methods - A total of 88 consecutive patients (52 men, mean age 68 +/- 8 years) with atypical chest pain, stable angina or suspicion of ischaemia at stress test were studied by MSCT and invasive coronary angiography (ICA). The MSCT images and multiplanar reconstructions were analysed regarding the presence of >= 50% coronary artery lesion. Results - All 88 scans obtained at a mean heart rate of 68 8 beats/min were interpretable. Sixteen coronary segments were evaluated in each patient. Of the 1320 segments examined, 148 (11 %) showed poor image quality. A total of 150 significant lesions were detected using ICA, and 80 of 150 (53%) were detected by MSCT Sensitivity, specificity, positive and negative predictive values were as follows: 53%, 97%, 68%, and 94%. Fifty-four patients had >= 50% coronary stenosis. The diagnosis was confirmed by MSCT in 42 patients and correctly ruled out in 30. By patient-based analysis, positive and negative predictive values were 91 % and 71 %. Conclusion - Although its specificity is high, the sensitivity of 16-slice MSCT for detecting 2: 50% coronary stenosis in non-selected patients submitted to ICA is rather low suggesting that for daily practice the diagnostic value of this technique should be improved.

Crohn's disease (CD) is a multifactorial disease with genetic heterogeneity. TNF-alpha plays a key role in the development of the mucosal lesions. The aim of our work was to study a single base pair polymorphism located in the promoter region of TNF gene, in a large population of CD patients with well defined phenotypes. One hundred and ninety-three patients with CD and 98 ethnically matched controls were studied. The -308 single base pair polymorphism of TNF gene was studied using an allele-specific polymerase chain reaction. Genotype and allelic frequencies were compared between patients and controls and between subgroups of patients defined by sex, age at diagnosis, familial history, location of disease, type of disease, extra-intestinal manifestations, and response to steroid treatment. In 29 patients a measure of TNF-alpha production by colonic biopsies was performed. The frequency of the allele TNF2 as well as the proportion of carriers of the allele TNF2 were slightly but not significantly lower in CD than in controls (11.9% versus 14.8% and 21.5% versus 27.6%, respectively). A more prominent difference in frequencies of allele TNF2 and in proportions of TNF2 carriers was found when comparing subgroups of patients. The frequency of allele TNF2 was significantly higher in steroid-dependent than in non-steroid-dependent disease (28.1% versus 10.3%; Delta = 17.8%, 95% confidence interval (CI) = 6.3-29.5%, P = 0.0027) and tended to be higher in colonic than in small bowel disease and in fistulizing than in stricturing disease. Furthermore, TNF2 carriers tended to be more frequent in patients with steroid-dependent than non-steroid-dependent disease (43.8% versus 19.3%; Delta = 24.5%, 95% CI = 3.6-45.4%, P = 0.022), in patients with fistulizing than stricturing disease (26.5% versus 9.6%; Delta = 16.9%, 95% CI = 1. 1-32.6%, P = 0.036), and in patients with colonic than small bowel disease (26.5% versus 11.1%; Delta = 15.4%, 95% CI = -0.8-31.6%, P = 0.063). Finally, patients carrying at least one copy of allele 2 were found to produce slightly more TNF-alpha at the colonic level. The -308 TNF gene polymorphism may have a slight influence on the behaviour of CD. The carriage of allele 2 may favour steroid-dependent disease and to a lesser extent fistulizing and colonic disease, possibly secondary to a more intense TNF-alpha-driven inflammatory reaction at the mucosal level.
