[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.

Novel integrated 3D multidetector computed tomography and fluoroscopy fusion for left atrial appendage occlusion procedures.

OBJECTIVES: This report demonstrates the application and feasibility of novel 3D-MDCT real-time fusion technology with fluoroscopy, for left atrial appendage (LAA) occlusion procedures. BACKGROUND: A successful LAA occlusion procedure relies on multiple imaging modalities, including TEE or 3D-MDCT, and fluoroscopy. Effectively integrating these imaging modalities may improve implantation safety and success. To our knowledge this technique has not been previously described for LAA occlusions. METHODS: This observational study compared clinical and procedural parameters for procedures performed with or without fusion integration. All patients had a pre-procedural 3D-MDCT for LAA measurements, along with 3D analyses of LAA morphology and surrounding structures. Using the image fusion software (Valve ASSIST 2, GE Healthcare, UK), landmarks were identified on fluoroscopy, and MDCT LAA anatomy outlines were then projected onto the real-time fluoroscopy image during the procedure, to guide all steps of the intervention. RESULTS: A total of 57 patients underwent LAA occlusion, with 16 performed using fusion software. In comparison to the pre-fusion group, reductions in contrast volume (21.0 ± 11.7 vs. 95.9 ± 80.5 ml, P < 0.001), procedure time (63.0 ± 22.0 vs. 87.3 ± 43.0 min, P = 0.01), and fluoroscopy time (6.2 vs. 8.3 min, P = 0.03) were observed. Incomplete sealing (0 vs. 14.6%, P = 0.16) and device deployment success (100 vs. 92.7%, P = 0.17) were not significantly different. CONCLUSIONS: The addition of this novel fusion technology is safe and feasible. To optimize LAA procedural success, fusion integration may offer a promising addition, or alternative, to current imaging modalities. © 2017 Wiley Periodicals, Inc.

Managing fatigue after cancer treatment: development of RESTORE, a web-based resource to support self-management.

OBJECTIVE: The aim of this study is to co-create an evidence-based and theoretically informed web-based intervention (RESTORE) designed to enhance self-efficacy to live with cancer-related fatigue (CRF) following primary cancer treatment. METHODS: A nine-step process informed the development of the intervention: (1) review of empirical literature; (2) review of existing patient resources; (3) establish theoretical framework; (4) establish design team with expertise in web-based interventions, CRF and people affected by cancer; (5) develop prototype intervention; (6) user testing phase 1; (7) refinement of prototype; (8) user testing phase 2; and (9) develop final intervention. RESULTS: Key stakeholders made a critical contribution at every step of intervention development, and user testing, which involved an iterative process and resulted in the final intervention. The RESTORE intervention has five sessions; sessions 1 and 2 include an introduction to CRF and goal setting. Sessions 3-5 can be tailored to user preference and are designed to cover areas of life where CRF may have an impact: home and work life, personal relationships and emotional adjustment. CONCLUSIONS: It is feasible to systematically 'co-create' an evidence-based and theory-driven web-based self-management intervention to support cancer survivors living with the consequences of cancer and its treatment. This is the first account of the development of a web-based intervention to support self-efficacy to manage CRF. An exploratory trial to test the feasibility and acceptability of RESTORE is now warranted.

FIP1L1-PDGFRA positive chronic eosinophilic leukaemia and associated central nervous system involvement.

Interstitial deletion involving chromosome 4q12 generates the novel tyrosine kinase fusion protein encoded by FIP1L1-PDGFRA, which is present in many patients previously labelled as having hypereosinophilic syndrome, initially reported in 2003. Reports in recent literature document excellent clinical and molecular response to the tyrosine kinase inhibitor imatinib (Glivec). This report describes the case of a 58-year-old lady, diagnosed with FIP1L1-PDGFRA positive hypereosinophilic disorder, who subsequently developed symptoms related to an intracranial lesion. Biopsy and molecular genetic studies confirmed a diffuse infiltrative lesion, with evidence of FIP1L1-PDGFRA gene fusion. Initiation of imatinib treatment led to impressive clinical and radiological response.

Prognostic factors for patients with chronic myeloid leukaemia in chronic phase treated with imatinib mesylate after failure of interferon alfa.

We assessed clinical results in 145 patients with chronic myeloid leukaemia in chronic phase who satisfied criteria for interferon-alpha failure and were thus eligible for treatment with imatinib at the Hammersmith Hospital. We used univariate and multivariate analyses to develop a risk score based on features defined after treatment for 3 months. We identified a low neutrophil count and poor cytogenetic response (<35% Ph-negative marrow metaphases) at 3 months as principal independent predictive factors and incorporated them into a three-tier prognostic scoring system for individual patients. For patients in the low-, intermediate- and high-risk groups, the probabilities of survival at 24 months were 100, 82 and 40% (P<0.0001) and progression-free survival 100, 66 and 15% (P<0.0001), respectively. This Hammersmith prognostic scoring system was validated with an independent cohort of patients treated at another UK centre.

Improving the management of chronic myeloid leukaemia.

Until recently the therapeutic options available to patients diagnosed with chronic myeloid leukaemia hinged on their suitability for allogeneic bone marrow transplantation. With the advent of new agents targeting the specific molecular pathways involved in the disease, drug therapies may have an increasingly important role in improving outcome.

Severe haemophilia following use of donor eggs: implications for screening of prospective donors.

Oocyte donation has become a common treatment modality for a range of infertility conditions. The Shared Egg Donation (SED) scheme is one of various strategies that now exist to try and overcome shortages, that have invariably occurred from the very success of oocyte donation procedures. Despite a reassuring positive profile that has been demonstrated, some residual concerns still exist with regard to the SED programme. We report the first case of severe haemophilia following use of donor eggs in the SED scheme. The case has not only illustrated potential problems that can occur with egg donation schemes, but also suggested a plausible model on which to base future management of similar cases. The case furthermore illustrates that there is no substitute for 'good practice' in ensuring those risks and concerns of egg donation programmes are kept to acceptable limits.
