We report a successful pulmonary embolectomy in a woman at the 27th week of pregnancy; we performed surgical pulmonary embolectomy under cardiopulmonary bypass to restore adequate hemodynamic stability and to relieve right ventricle strain. We discuss the decision made for the preferred anticoagulation drug in the setting of heparin-induced thrombocytopenia in the gravida. The pregnancy was carried to term and she delivered a healthy boy at 38 weeks of gestation.

Cardiac surgery in patients with a history of sternoturnover has been rarely reported and is a surgical challenge because it is unknown how median sternotomy or the use of a sternal retractor affects the postoperative stability of the thorax and respiratory function. We report a successful coronary artery bypass grafting through left thoracotomy in a patient treated with sternoturnover for pectus excavatum. Case presentation: A 53-year-old man, who underwent sternoturnover in his childhood, was diagnosed with acute myocardial infarction, and percutaneous coronary intervention was performed as the acute treatment of the culprit lesion. Because residual lesions were present, he was referred to our department for coronary artery bypass grafting. Enhanced computed tomography revealed bilateral occlusions of the internal thoracic arteries and a small fragile sternum after fixation. Considering postoperative respiratory dysfunction associated with instability of the thorax following median sternotomy, we selected left thoracotomy for coronary artery bypass grafting. Convalescence was uneventful without any respiratory complications. Conclusion: Left thoracotomy is useful for coronary artery bypass grafting in patients previously treated with sternoturnover for pectus excavatum because it can avoid respiratory dysfunction associated with median sternotomy.

After approximately 4 weeks of recovery from endocarditis and haemiparesis, follow-up echocardiography revealed a newly formed pseudoaneurysm. Although coronary angiogram was normal at this point, early septic embolism to a coronary artery and subsequent myocardial infarction [2] was the most probable mechanism for pseudoaneurysm formation in this patient. Late gadolinium enhancement MRI [2] of the heart to visualize infarction was not performed due to reduced renal function. He underwent uneventful left ventricular repair and was discharged in good condition.

The mean age was 58 years (37-77 years). The average procedure and assisted ventilation times were 56.5 min (40-110 min) and 86 min (70-140 min) respectively. Three patients experienced cardiac arrhythmias which regressed. The patients were discharged home on the 5th day (3-11 days). In contrast to needle biopsy which only provided a diagnosis in 3 cases, the histopathological findings were diagnostic in all cases: 12 malignant and 3 benign pericardial effusions with correction of the presumed clinical diagnosis in the latter 3 cases. The average follow-up was 10 months (7 days-3.5 years). There was no operative mortality. Global survival at 1 year was 66%, death being generally caused by a complication of the malignant disease. There were no deaths in the 3 patients with benign pericardial effusions, underlying the necessity of an accurate etiologic diagnosis before assuming malignant pericardial invasion. There were no recurrences of the pericardial effusion and the ventilatory status of these patients was adapted for everyday activities. In patients with malignant disease, the construction of a pleuro-pericardial window by videosurgery is a satisfactory approach. It provides etiologic diagnosis and is well tolerated by patients in poor general condition with no operative deaths, low morbidity and definite improvement in the patients' comfort.

The aim of this study is to evaluate the biological effect of aspirin in these conditions. We evaluated thromboxane A2 synthesis, indirect markers of platelet activation levels and inflammatory process in aspirin treated patients undergoing CABG surgery.Methods: Twenty aspirin treated (160 mg/day) patients were enrolled prospectively. We evaluated the association between aspirin usage for more than 1 month and urine 11-dehydro thromboxane B2 (11DHTB2) level, as well as soluble P-Selectin (sPsel) and soluble CD40 ligand (sCD40L) serum levels during the 7 days following surgery. Considering the variation of platelet count following CABG surgery and the known relation between sCD40L level and platelet mass (2), we reported sPsel and sCD40L serum levels to the platelet count. Blood and urine samples were collected at H0 (before surgery) and at H36, 72, 168 post surgery. Inflammatory process was also investigated by C-reactive protein and fibrinogen level determinations.Results: Main data are expressed in table 1. 11DHTB2 (metabolite of thromboxane A2) increased at H36 following surgery and decreased progressively until day 7 without reaching the preoperative level. 11DHTB2 didn’t correlate with the inflammatory process (C-reactive protein and fibrinogen levels). Only concomitant increase of leukocytes count and 11DHTB2 level was observed. In the other hand, at H36 post surgery, sPsel and sCD40L levels slightly increased. Soluble P-selectin level progressively decreased until H168 while sCD40L level remain stable up to H168. At least, no correlation was found between sPsel, sCD40L and 11DHTB2.Conclusion: These data indicated that, under aspirin treatment, a slight and transitional platelet activation occurred after CABG surgery. According to the lake of correlation between sPsel, sCD40L levels and 11DHTB2 level, we hypothesized that 11DHTB2 is produced by an another source (i.e leukocytes) which occurred independently to platelet activation.Biological data.

L'appreciation de son impact a ete negligee et il est au centre de nombreux axes de recherche. Le porc presente de nombreuses similitudes physiologique, anatomique et histologique avec l'homme. Un poumon isole perfuse ventile de porcs, des modeles d'autotranslantation et d'ischemie chaude de reins de porc ont ete developpes dans l'unite (INRA Surgeres, plateforme IBISA) pour une etude detaillee du syndrome d'ischemie-reperfusion chaude ou froide, a court ou long terme. Sur le plan pulmonaire, nous avons teste l'interet du polyethylene glycol dans une solution de conservation normo potassique. Cette solution permet une meilleure conservation des greffons pulmonaires. Cette etude confirme la capacite de la Spectroscopie par Resonance Magnetique Nucleaire du proton a apprecier la qualite du greffon par l'analyse du lavage bronchiolo-alveolaire Sur notre modele porcin d'ischemie froide avec transplantation autologue, nous avons demontre un role important des cellules T CD4+ dans les lesions d'ischemie reperfusion renale et la modulation possible de cette ischemie reperfusion par des conditions de conservation : ajout de trimetazidine aux differentes solutions de conservation, interet des solutions extracellulaires (haute concentration en Na+), interet du PEG. En ischemie chaude, phase initiale des prelevements a coeur arrete ou mimant les phases preoperatoires d'instabilite hemodynamique des donneurs limites, l'interet de la trimetazidine a ete retrouve tant dans les phases precoces que tardives pour limiter le developpement de la fibrose. Un certain nombre d'etudes ont examine le role des cellules inflammatoires dans la genese des lesions post-ischemiques, notamment du leucocyte. Nous avons ainsi teste en ischemie froide et chaude un inhibiteur selectif de la P selectine, le TBC 1269. Il reduit les lesions d'ischemie reperfusion renale de porc apres ischemie chaude et froide, avec une reduction des lymphocytes T CD4+ et de l'infiltration macrophagique, et a long terme de la fibrose. De plus, l'ischemie produit des mediateurs qui potentialisent la reponse inflammatoire, notamment via le TNF α dont la production est induite par l‟activation de la proteine « p38 mitogen -activated kinase » (MAPK). Le FR167653 (FR) inhibe la p38 MAPK. Nous avons evalue l'influence de l'ischemie chaude, de la masse nephronique et du FR pendant les stades initiaux et a long terme sur la fibrose et l'inflammation. Le FR est protecteur du rein en ischemie chaude. Il reduit la production de facteurs pro inflammatoires MCP-1 et TNF-α, diminue l'expression du TGF-β, diminue l'activite de fibrogenese et preserve l'integrite renale. La maitrise des membranes d'oxygenation chez le porc, la maitrise des modeles d'ischemie chaude et froide sur un modele de transplantation renale, nous permet de disposer de toutes les sequences du prelevement a coeur arrete chez le porc. Une large perspective s'ouvre a nous pour evaluer cette double sequence d'ischemie specifique de ce prelevement a coeur arrete, afin d'apprehender les moyens de proteger au mieux ces greffons limites.

A longer delay in establishing the diagnosis and more heart failure in the surgical group were noted in this study as factors that negatively affect the outcome of surgery [19]. CLINICAL BOTTOM LINE Unless a patient is not a surgical candidate, in PVE, surgery is the treatment of choice. This is particularly the case in patients who develop complications as a result of PVE. These complications include heart failure, valvular dysfunction, valvular regurgitation or obstruction, valve dehiscence and annular abscess. In these patients, early surgery also improves the outcome and increases the survival. Infection with S. aureus should be considered an indication for surgery in PVE even without cardiac or valvular complications. These patients should undergo surgery as soon as possible before cerebral complications develop. In patients with other microorganisms, especially where the organism is sensitive to the particular antibiotic treatment regime and no structural damage or cardiac complications have occurred, surgery can be postponed or reconsidered if there is response to the treatment. This option should be considered for selected patients only and cardiac surgeons should be involved from the early stages of the diagnosis.
