Transcatheter aortic valve implantation (TAVI) is increasingly performed and represents a relatively safe alternative treatment for high risk patients denied to surgical aortic valve replacement. TAVI is performed at the University Hospital of Liege since July 2008 with the Medtronic CoreValve Revalving® system by femoral or subclavian access. This paper exposed the technique of TAVI and the nursing care required after this procedure. [less ▲]

We reported the case of spontaneous rupture of a coronary artery. It was a 56-year-old man admitted for dyspnoea and anterior thoracic pain. The most striking feature on physical examination was the marked cyanosis of his face, upper part of the thorax and the upper limb. The patient was haemodynamically unstable with tachycardia and hypotension. Cardiac tamponade was confirmed by echocardiography and computed tomography of the thorax. The patient was transferred for surgery. Emergency sternotomy revealed pericardial bloody effusion and a continuous bleeding around the posterior interventricular artery. No other per-operative findings could explain the haemopericardium. Haemostasis was obtained by a suture of the bleeding coronary artery. [less ▲]

The cyclic appearance of dynamic left ventricular outflow tract obstruction during mechanical ventilation, according to the phasic changes in preload, is described in this article. Hemodialysis-induced fluid removal resulted in preload dependence as evidenced by the pulse pressure variation in a 56-year-old critically ill patient. The clinical picture was suggestive of myocardial failure. Transthoracic echocardiography disclosed dynamic left ventricular outflow tract obstruction associated with systolic anterior motion of the mitral valve. Progressive fluid restitution resulted in a parallel decrease in both the degree of dynamic obstruction and pulse pressure variation. During fluid loading, dynamic obstruction disappeared at first during the inspiratory phase of intermittent positive pressure ventilation corresponding to the phasic increase in left ventricular preload. Further fluid loading resulted in the disappearance of dynamic obstruction during both inspiratory and expiratory phase of intermittent positive pressure ventilation. This is the first reported case clearly relating left ventricular outflow tract dynamic obstruction to preload dependence during mechanical ventilation in a critically ill patient without predisposing anatomical factor.

BACKGROUND: The aim of this study was to determine whether two-dimensional speckle tracking of longitudinal myocardial deformation can detect limited contractile reserve during exercise in patients with asymptomatic degenerative mitral regurgitation (MR). METHODS: Seventy-one patients with degenerative MR and normal left ventricular (LV) ejection fractions underwent quantitative exercise echocardiography. RESULTS: Compared with 23 normal subjects matched for age and sex, LV volumes were greater in patients with MR. At rest, global longitudinal strain (GLS) was lower in patients, indicating subclinical LV dysfunction. During exercise, the extent and the magnitude of changes in GLS were larger in controls than in patients with MR. On multivariate regression analysis, left atrial volume at rest and changes in GLS at peak exercise were independently associated with changes in LV ejection fraction. CONCLUSION: In asymptomatic patients with degenerative MR, subnormal LV function can be reliably identified by two-dimensional strain imaging. Limited exercise LV longitudinal contractile recruitment during exercise predicts postoperative LV dysfunction. [less ▲]

BACKGROUND: Thymectomy is considered as an effective therapeutic option for patients with myasthenia gravis (MG). This study reports the experience of our centre's investigation into the efficacy and the safety of the procedure and the influence of different pre-operative factors on the surgical outcome. METHODS: A retrospective chart review/interview was made of 19 consecutive patients who underwent extended transsternal thymectomy for MG from 1992 to 2003. The severity of the disease was determined according to the Osserman Classification. Efficacy was measured by determining the change in clinical status, the rate of remission during follow-up, and the reduction in medication requirements after thymectomy. Complete remission (CR) was defined as asymptomatic off medication for 6 months. The CR rate was calculated using the Kaplan-Meyer method. RESULTS: The mean age of the patients at surgery was 34 years (range, 9-63) and 78.9% were female. Mean length of follow up was 86 months (range, 24-163). The overall complication rate was 10.6% (1 episode of atrial fibrillation and a left recurrent laryngeal nerve palsy that resolved after the first postoperative month). There was no operative mortality. The mean hospital stay was 9.4 days (range, 5-23). The crude CR rate was 32% (n = 6). The Kaplan-Meier estimate of CR was 42% at 6 years. Age, gender, duration of symptoms, thymic histology, Osserman stage and the presence of thymoma were not identified as prognostic variables. The average daily dose of Medrol and Mestinon decreased significantly between the pre-operative period and the last follow-up (Medrol, p = 0.0081; Mestinon, p = 0.0013). CONCLUSIONS: Transsternal thymectomy for MG is safe and effective. It benefits patients with MG at all stages. Patients with thymoma are not associated with poorer remission rates. Complete responses are durable, as the CR rate remains stable over time. [less ▲]

Nous rapportons le cas d'un patient de 67 ans atteint d'un syndrome myélodysplasique et qui a développé une mucormycose pulmonaire avec extension tout à fait exceptionnelle vers le rachis dorsal responsable d'un paraplégie aiguë. Après échec d'un traitement probabiliste anti-aspergillaire, c'est finalement l'analyse des prélèvements obtenus lors de la laminectomie décompressive qui a fourni le diagnostic mycologique. En raison d'une altération majeure de l'état général, la lobectomie prévue n'a pu être réalisée et malgré l'adaptation du traitement antifongique (Abelcet, Posaconazole), le patient est décédé. La mucormycose (ou zygomycose) pulmonaire est une infection fongique peu commune qui touche essentiellement les patients immuno-déprimés. Le champignon pathogène fait partie des zygomycètes dont la caractéristique principale est la capacité d'angio-invasion. L'invasion périneurale est une autre voie de propagation récemment mise en évidence. Les difficultés thérapeutiques associées à cette pathologie sont liées au terrain d'immunodépression, aux difficultés d'obtenir rapidement un diagnostic précis ainsi qu'à l'absence de sensibilité du Mucor aux antifongiques récemment introduits (V-Fend, Cancidas). Ceci souligne le risque inhérent à un traitement antifongique empirique par ces agents et la nécessité d'un prélèvement biopsique précoce en cas de non-réponse au traitement. [less ▲]

Surgery for abdominal aortic aneurysm may be challenging when rare renal or venous anomalies are present. This article reports two similar cases of aortic abdominal aneurysm associated with horseshoe kidney and left-sided inferior vena cava treated with a transperitoneal approach. Preoperative knowledge of the anatomic situation enabled appropriate aneurysm repair. Operative strategy is discussed. This report describes an uncommon venous vascular malformation complex and stresses the importance of computed tomography imaging not only in assessing the characteristics of the aneurysmal disease but also in detecting variations in pertinent vascular or parenchymal anatomy.

Recently a new computed tomography semiology of the pulmonary adenocarcinoma was highlighted. Studies on ground-glass nodule and on mixed nodule showed the relation between these radiological images and the different anatomopathological forms of lung adenocarcinoma. Ground-glass opacity can correspond to precancerous lesions and morphological characteristics of nodules are correlated with the prognosis. The presence of spiculation, pleural retraction and air bronchogram is significantly more important in neoplasic lesions. The presence or the apparition of a solid component inside the nodule or the presence of indentation is highly suggestive of adenocarcinoma. A lesion smaller than 20 mm and persistant after 1 month must be, either followed up, or removed by a limited surgical resection. Lesions larger than 20 mm or associated with a solid component must be treated by conventional surgery. [less ▲]

The case of a 30-year-old non-Marfan woman who developed a type III acute aortic dissection 5 days after delivery, followed within 16 h by an independent type II dissection, is reported. Preoperative CT scan imaging and TEE suggested metachronous type II and type III dissection. This was confirmed at surgery, where limited dissection of the aortic root without communication with the isthmic area via the aortic arch was evidenced. The patient underwent repair of the aortic root and adjacent ascending aorta and was medically treated for her type III dissection. This is the first report of metachronous acute aortic dissections in puerperium. [less ▲]
