    Abstract Transcatheter valve implantation (TAVI) is becoming a routine procedure to treat severe symptomatic aortic stenosis. It is associated with complications different from those of conventional aortic valve surgery. We describe an 80-year old man who developed an apical left ventricular (LV) false aneurysm 3 months after transapical TAVI (TA-TAVI) complicated postoperatively by a surgical site infection (SSI). Three months earlier, an Edwards Sapien bioprosthesis no. 29 had been successfully inserted transapically because of severe comorbidities and a very large aortic annulus. His postoperative course was complicated by acute respiratory failure, gastrointestinal bleeding and a surgical site infection of the thoracic incision; Escherichia coli and Klebsiella pneumonia were isolated. After surgical debridement drainage and prolonged antibiotic therapy, the wound healed correctly. His emergency chest computed tomography upon readmission for the acute onset of a beating tumefaction at the TA-TAVI site showed a false aneurysm of the LV apex. The apex was closed directly during emergency surgery. The postoperative course was uneventful. Surgical site infection after TA-TAVI, its frequency, treatment and potential role as an underlying cause of this severe complication are discussed.

    Abstract We compute the momentum- and frequency-dependent longitudinal spin structure factor for the spin-1/2 XXZ Heisenberg spin chain in a magnetic field, using exact determinant representations for form factors on the lattice. Multiparticle (i.e., multispinon) contributions are computed numerically throughout the Brillouin zone, yielding saturation of the sum rule to high precision.

    Abstract Infectious aortitis has become a rare disease thanks to the widespread use of antibiotics. We report the case of a patient who, 15 days after initiation of antibiotics for bacteraemia due to methicillin-resistant Staphylococcus aureus (MRSA), developed acute chest pain followed by haemodynamic instability. A tamponade due to a rupture into the pericardium of the ascending aorta at the site of an atherosclerotic plaque was diagnosed by an emergent chest contrasted computed tomography (CT). Intraoperatively, the septic nature of the rupture was suspected. All aortic atherosclerotic plaque samples grew MRSA. Postoperatively, the patient had an uneventful recovery after 12 weeks of antibiotic therapy. Transoesophageal echocardiography and chest CT were normal at 3 months after cessation of antibiotics. This case report permits the review of some characteristics of this disease, its physiopathology as well as the therapeutic implications.

    Abstract Abdominal complications following cardiac surgery remain unusual, but are associated with high mortality. The most common abdominal surgical complications are mesenteric ischaemia, diverticulitis, pancreatitis, gastrointestinal bleeding and cholecystitis. We describe a case of a 73-year old woman with acute abdominal pain mimicking cholecystitis on day 10 after aortic valve replacement. An abdominal examination showed tenderness of the right upper quadrant with Murphy's sign. Complete blood count, blood chemistries and urinalysis were normal as were the abdominal and chest X-rays and abdominal ultrasonography. The abdominal computed-tomography (CT) scan enabled us to rule out cholecystitis, as it demonstrated the typical appearance of epiploic appendagitis on the right colon, 1 cm below the gallbladder. Epiploic appendagitis results from twisting, kinking or venous thrombosis of an epiploic appendage. Depending on its localization, it mimics many diagnoses requiring surgery: colitis, diverticulitis, appendicitis and cholecystitis. An abdominal CT scan is the diagnostic imaging tool of choice. All physicians involved in post-cardiac surgery care should be aware of this self-limiting disease that usually resolves with non-steroidal anti-inflammatory drugs and watchful waiting, and to avoid unnecessary surgery because the spontaneous evolution of epiploic appendagitis is usually benign.

    Abstract Objective: To determine the feasibility, safety, and efficacy on PaO(2)/F(I)O(2) ratio of prone positioning (PP) for acute respiratory distress syndrome (ARDS) after cardiac surgery.
    Design: Retrospective review of information entered prospectively in the authors' database.
    Setting: A private community nonteaching hospital.
    Participants: Sixteen patients who developed ARDS after cardiac surgery from January 2004 through June 2005.
    Interventions: PP to improve oxygenation.
    Measurements and main results: After a median duration of 18 (range, 14-27) hours in PP, PaO(2)/F(I)O(2) improved in 14 (87.5%) patients. For the entire population, median PaO(2)/F(I)O(2) rose from 87 (range, 56-161) before PP to 194 (range, 94-460; p < 0.05) after it. After supine repositioning (SR), PaO(2)/F(I)O(2) declined to 146 (range, 72-320; not significant). PaO(2)/F(I)O(2) at the end of PP and 1 day after SR were comparable, respectively, 194 (range, 94-460) and 184 (range, 105-342). No severe complication was associated with PP, but 5 patients developed pressure sores and 2 others had superficial sternal wound infections. Intensive care unit mortality of 37.5% reflected the number of organ failure(s); there were no deaths with 2 failures, and 60% with > or = 3 organ failures died (p = 0.03). Mortality rates were comparable regardless of whether patients were PaO(2)/F(I)O(2) responders or their PaCO(2) decreased by > or = 1 mmHg.
    Conclusion: PP to treat ARDS after cardiac surgery is feasible, safe, and can efficiently improve oxygenation. Measures to prevent pressure sores are mandatory.

    Abstract In order to analyze the quality of life (QoL) or frailty after AVR for octogenarians, we studied 84 patients older than 80 years who underwent aortic valve replacement alone or in combination with coronary artery bypass, between April 1998 and December 2001. Follow-up was performed in May 2002 with a telephonic interview to evaluate the self-rated QoL, health, and three frailty markers: falls, activity of daily living (ADL) and mood disorder. In-hospital mortality was 16.7%. Fourteen deaths occurred during the follow-up: survival estimates were 85.5% at 1 year and 68.6% at 3 years. Forty-one patients (73.2%) were in New York Heart Association (NYHA) classes I-II for dyspnea and 42 patients (75.0%) were free of angina. Fifty-one patients (91.1%) lived in their own homes. Forty-eight (85.7%) had at least one frailty marker: falls (26.8%), loss of autonomy for ADL (27.0%) or suspected depression (20.2%). All frailty markers were associated with self-rated QoL but not with self-rated health. AVR for octogenarians is associated with good outcome but this population is frail and further studies should assess the usefulness of pre- and postoperative geriatric approach.

    Abstract Objectives: Transcatheter aortic valve implantation (TAVI) has emerged as an effective treatment for high-risk patients with severe aortic stenosis (AS). The aim of our study was to compare the prevalence, characteristics and outcomes of high-risk patients treated prior to and after the availability of TAVI in our high-volume surgical institution.
    Methods: Among 879 consecutive patients treated 2 years before ('pre-TAVI era') and after ('modern era') the availability of TAVI in our institution, 83 patients were at high risk [defined by logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) >20%].
    Results: Among all patients treated for severe AS, the prevalence of high-risk patients was higher in the modern era (12.7 vs 4.9%, P < 0.0001). In the modern era, high-risk patients were treated by TAVI in 89% of cases. Despite similar logistic EuroSCORE (34.9 vs 34%, P = 0.96), the clinical characteristics of these patients have evolved: high-risk patients in the modern era were older (85.3 ± 5.9 vs 78.5 ± 6.5 years, P = 0.0005) and presented more frequently with New York Heart Association class III-IV (92.3 vs 61.1%, P = 0.003), while high-risk patients treated by surgical aortic valve replacement in the pre-TAVI era presented more frequently with a critical preoperative status (33.3 vs 7.7%, P = 0.01), lower left ventricular ejection fraction (41 ± 14 vs 49 ± 15%, P = 0.05) and a history of recent myocardial infarction (27.8 vs 6.1%, P = 0.02). The overall 1-year survival was not different for high-risk patients treated in the pre-TAVI era or in the modern era (61 ± 11 vs 68 ± 6%, P = 0.52).
    Conclusions: The availability of TAVI has increased the prevalence of high-risk patients treated for severe AS and changed the clinical features of this kind of patients who were rarely surgically treated before. The 1-year survival was similar between pre-TAVI and modern eras.
