Deep sternal wound infection is the major infectious complication in patients undergoing cardiac surgery, associated with a high morbidity and mortality rate, and a longer hospital stay. The most common causative pathogen involved is Staphylococcus spp. The management of post sternotomy mediastinitis associates surgical revision and antimicrobial therapy with bactericidal activity in blood, soft tissues, and the sternum. The pre-, per-, and postoperative prevention strategies associate controlling the patient's risk factors (diabetes, obesity, respiratory insufficiency), preparing the patient's skin (body hair, preoperative showering, operating site antiseptic treatment), antimicrobial prophylaxis, environmental control of the operating room and medical devices, indications and adequacy of surgical techniques. Recently published scientific data prove the significant impact of decolonization in patients carrying nasal Staphylococcus aureus, on surgical site infection rate, after cardiac surgery., (Copyright © 2013 Elsevier Masson SAS.

Background: When implanted in patients with biventricular failure, the CardioWest total artificial heart has asserted itself over time as a reliable bridge-to-transplant device that as yet is used by only a few international teams. The aim of this single-center retrospective study is to assess both the comorbidity and survival of patients awaiting heart transplants while receiving circulatory support with a CardioWest total artificial heart., Methods: From 1990 to December 2006, 42 patients received a CardioWest total artificial heart at our center. Mean age at the time of implantation was 45.7 +/- 9.5 years, and 40 patients (95%) were men. Idiopathic or dilated cardiomyopathy was diagnosed in 45.2% (n = 19) of the patients and ischemic cardiomyopathy in 42.8% (n = 18). Average body surface area was 1.9 +/- 0.22 m(2)., Results: Duration of support was 1 to 292 days (mean, 101 +/- 86 days). Twelve patients died (28.5%) while receiving device support, and 30 patients (71.5%) underwent transplantation. Actuarial survival rates for the transplanted patients were 90% (n = 25), 81% (n = 14), and 76% (n = 10) at 1, 5, and 10 years, respectively. Causes of death during device support included multiorgan failure in 6 (50%), sepsis in 2, acute respiratory distress syndrome in 2, alveolar hemorrhage in 1, and other cause in 1. There were no device malfunctions that led to patient death. Adverse events included stroke in 3 patients (7%) and infections in 35 patients (85%) during support., Conclusions: The CardioWest total artificial heart is an excellent bridge-to-transplant device for patients with biventricular failure. Our study demonstrates excellent safety, reliability, and efficiency. Exceptional outcome after transplantation underlines its capacity to aid in end-organ recovery.

Objectives: The study was conducted to determine the long-term outcome of patients who underwent heart transplantation 15 to 20 years ago, in the cyclosporine era, and identify risk factors for death., Methods: A retrospective analysis was done of 148 patients who had undergone heart transplantation between 1985 and 1991 at a single center. Operative technique and immunosuppressive treatment were comparable in all patients., Results: Actuarial survival rates were 75% (n = 111), 58% (n = 86), and 42% (n = 62) at 5, 10, and 15 years, respectively. The mean follow-up period was 12.1 +/- 5.6 years for patients who survived more than 3 months after transplantation (n = 131). The major causes of death were malignancy (35.8%) and cardiac allograft vasculopathy (24.7%). No death related to acute rejection was reported after the first month of transplantation. Graft coronary artery disease was detected on angiography in 66 (50.3%), and 7 (5.3%) had retransplantation. Malignancies developed in 131 patients (48.1%), including skin cancers in 31 (23.6%), solid tumors in 26 (19.8%), and hematologic malignancies in 14 (10.6%). Severe renal function requiring dialysis or renal transplantation developed in 27 patients (20.6%). By multivariable analysis, the only pre-transplant risk factor found to affect long-term survival was a history of cigarette use (p < 0.0004)., Conclusions: Long-term survival at 15 years after cardiac transplantation remains excellent in the cyclosporine era. Controlling acute allograft rejection can be achieved but seems to carry a high rate of cancers and renal dysfunction. History of cigarette use affects significantly long-term survival in our study.

Background: The liberalization of lung-donor criteria and the use of marginal donors have been advocated to face the current shortage of donors in lung transplantation. However, the impact of donor characteristics on the outcome of lung transplantation is still largely unknown. We aimed to determine, on a large cohort of patients, the effect of donors characteristics on short- and long-term outcome of lung transplantation, Methods: Between 1988 and 1998, a total of 785 adult patients underwent single-lung transplantation (n = 270), bilateral-lung transplantation (n = 251), and heart-lung transplantation (n = 264) in 7 centers in France. We constructed several multivariate models to assess the relationship between donor characteristics and early gas exchange, duration of mechanical ventilation, and long-term survival after lung transplantation., Results: Among donor characteristics, donor gas exchange before harvest was found to be significantly associated with recipient early gas exchange, duration of mechanical ventilation, and long-term survival after adjustment for potential confounding variables. Moreover, nonlinear modeling showed a steep increase in the relative risk of death when donor PaO2/FiO2 before harvest was below 350 (hazard ratio 1.43; 95% confidence interval 1.10-1.85; p = 0.01). Donor and recipient sex mismatch were also found to be significantly associated with long-term survival., Conclusions: Although liberalization of lung-donor criteria may be considered to overcome the shortage of lung donors, our data suggest that the violation of the gas-exchange criterion should be avoided.

We report a case of a young woman suffering from a steady anthracycline-induced myocardiopathy with a decreased left ventricular function on echocardiography. A pregnancy was initiated, without worsening of the cardiopathy until 34 weeks. Nine days after delivery, an acute heart failure was observed leading to heart transplantation after cardiac assistance with heart cardiac device. As pregnancy is an extended stress test for a chronic failing heart, a multidisciplinary decision of pregnancy initiation and follow up should be preferred in pre and postpartum period, when such a cardiopathy exists.

Postpneumonectomy syndrome is defined as an airway obstruction due to mediastinal shift and rotation after pneumonectomy. A patient who had undergone a left pneumonectomy for bronchial carcinoma 13 years before presented with tension pneumothorax of her remaining lung. Although all factors relevant to the development of postpneumonectomy syndrome were ascertained, the patient had a pneumothorax rather than an airway obstruction. This pneumothorax was treated surgically. The goal of this operation was to reduce the right pleural cavity volume by implanting an intrapleural prosthesis in the pneumonectomy cavity. This treatment is identical to that used for postpneumonectomy syndrome, which allows the right lung to be rejoined with the thoracic wall.

Background: We have retrospectively studied 254 patients who underwent a bivalvular mechanical mitral-aortic replacement in the cardiovascular and thoracic surgery unit of Nantes from 1979 to 1989. The follow-up was 22 years (1979 to 2001). The last patient was operated on 12 years before the end of the follow-up., Methods: All mitral prostheses were St. Jude Medical (SJM) bileaflet valves, and the aortic prostheses were 124 monodisc Björk-Shiley valves, 3 Sorin prostheses, and 127 St. Jude Medical bileaflet prostheses. The mean age was 56.8 +/- 8.5 years with a sex ratio equal to 1. Rheumatism as the etiology predominated with 79.5%. Ninety-seven percent of the patients were followed for a total of 2,779 patient-years and a mean of 11.7 years., Results: Operative mortality was 7.08%. Freedom from overall mortality and valve-related mortality at 22 years were 45.7% +/- 3.6% and 73.1% +/- 3%, respectively. The linearized rates of thromboembolic and hemorrhagic events were 1.07% and 0.9% per patient-year, respectively. Multivariate analysis showed age (p < 0.002), sex (p < 0.01), and degenerative etiology (p = 0.04) as independent factors of late mortality, and age, sex, degenerative disease, and tricuspid pathology were related to valve-related mortality., Conclusions: This study shows good results after mechanical mitral-aortic replacement in terms of survival rate and quality of life in surviving patients, and outlines the factors influencing long-term results as compared with isolated mitral valve replacement.

Background: We compared the morbidity and mortality rates of patients who had urgent heart transplantation or transplantation after bridging with a ventricular assist device, with the rates of patients whose clinical stability allowed them to wait at home., Methods: From March 1985 to December 2000, 404 patients underwent heart transplantation in a single center. There were 273 patients with UNOS status 2 (US 2), 103 patients with UNOS Status 1A (US 1A), and 28 patients with UNOS Status 1B (US 1B). We compared the groups retrospectively with respect to pretransplantation status and operative results., Results: Despite more severely impaired hemodynamics and a significantly higher preoperative infection rate in US 1A and 1B patients, there were no statistically significant differences in survival rates among the three groups. Donor sex and age, cytomegalovirus and toxoplasmosis, mismatch rate, ischemic time, method of myocardial protection, and operative technique did not differ statistically among the three groups. Length of intensive care unit stay, postoperative morbidity, first year postoperative rejection rate, and graft occlusive vascular disease rate were statistically similar among the three groups. Although pretransplantation cancer assessment was less complete in US 1A and 1B than in US 2 patients, the late-cancer rate was not statistically different among the three groups., Conclusions: These data suggest that urgently transplanted patients have both early and long term morbidity and mortality similar to those of patients waiting for transplantation at home or with a ventricular assist device.

The purpose of this study was to report a single center's experience of 5 new pregnancies following heart-lung transplantation. These 5 pregnancies gave rise to 4 live births. Vaginal delivery occurred at a mean of 38 +/- 1 weeks of amenorrhea (range, 37-39 weeks) and the mean birth weight was 3,143 +/- 757 grams (range, 2,270-3,990 grams). Mean maternal forced expiratory volume in 1 second (%) before, during (sixth month), and after (1 year) pregnancy was 87 +/- 18, 87 +/- 22, and 88 +/- 17, respectively (p = NS). In conclusion, pregnancy after heart-lung transplantation can be associated with a good prognosis for mother and child.

Background: Several storage methods using a wide variety of extracellular or intracellular solutions applied either as continuous perfusion, intermittent perfusion, or simple immersion of the heart have been commonly used. We have performed a prospective randomized multicenter study of 70 cardiac transplantation recipients to evaluate the Celsior solution for cardiac preservation., Methods: Seventy consecutive patients were included in this trial and received a cardiac graft arrested and preserved with Celsior. The first follow-up period was 1 month. The mean age of the recipients was 49 years (range, 28 to 66 years), and 81.7% were male. The main disease was nonobstructive cardiomyopathy (64.3%). The age range of donors was between 14 and 56 years with a mean of 33 years. The majority of grafts (73%) were stored in 1 L of Celsior. A midterm follow-up at 5 years was performed and was 100% complete., Results: The operative mortality (<30-day) rate was 6 of 70 (8.6%). Sixty-three patients (90%) had at least satisfactory hemodynamic measurements on day 2. The first postoperative echocardiograms showed good myocardial performance for 90% of the grafts. Actuarial survival rate at 5 years was 75% +/- 5.1%., Conclusions: The use of Celsior in cardiac transplantation was safe and very effective. This solution proved very valuable in at-risk patients.

Background: A retrospective study was conducted to analyze the results of St. Jude Medical mitral valve replacement., Methods: From January 1979 to December 1989, 870 patients (54% women, 46% men; mean age, 55.8 +/- 6.2 years) underwent mitral valve replacement with the St. Jude Medical prosthesis. Of these operations 616 were isolated mitral valve replacements and 254 were double valve replacements. Coronary artery bypass grafting was performed concomitantly in 55 patients (6.3%)., Results: Overall, early mortality was 5.05%, with 4.2% for the isolated mitral valve procedure and 7.08% for the double valve replacement. Follow-up at 15 years was complete in 859 patients (98.74%). Mean follow-up time was 93.5 months, for a total of 6,436 years. Actuarial survival at 15 years was 59.5% +/- 5%, 60.5% +/- 6%, and 56.9% +/- 9%, for the entire group, the isolated mitral valve and double valve procedures, respectively. Multivariate analysis identified age, sex, hospital stay, and preoperative mitral regurgitation as independent prognosis factors for overall mortality. Of 606 patients alive at the latest follow-up, the New York Heart Association class improved significantly (from 67% class III/IV before the operation to 88% class I/II after the operation). All patients received warfarin to maintain an international normalized ratio between 3.5 and 4. The linearized rates (% per patient-year) of thrombosis, thromboembolism, and major hemorrhage were, respectively, 0.21, 0.75, and 0.94 for the entire group; 0.18, 0.67, and 0.88 for the isolated mitral valve operation; and 0.15, 0.92, and 1.08 for the double valve replacement. For the entire group the freedom from thrombosis and thromboembolism at 15 years was 98.1% +/- 1% and 88% +/- 4%, respectively. No case of structural dysfunction occurred. The freedom from paravalvular leak and endocarditis at 15 years was 95.3% +/- 2% and 97.3% +/- 2.4%, respectively. The probability of remaining free from reoperation at 15 years was therefore 95.6% +/- 2.5%., Conclusions: These results confirm that the St. Jude Medical valve is a reliable prosthesis with very low thrombosis and thromboembolism rates, allowing the use of a low dose of anticoagulation with an international normalized ratio of about 3.

Background: Heart lung transplantation for++ cystic fibrosis is now performed in patients with severe lung disease but the experience is still scarce with the exception of some specialized centers., Patients and Methods: Twenty-one patients underwent heart-lung transplantation between September 1989 and November 1994 in our institution, with a high standard of reliability in tracheal anastomosis and with a low incidence of hospital mortality (5%)., Results: The actuarial patient survival is 90.2% (95% confidence interval, 70 to 97%) at 1 year and 75.7% (95% confidence interval, 51 to 90%) at 3 and 4 years. The mean forced expiratory volume in 1 second (FEV1) increases from 20.1% predicted preoperatively to 76.1%., Conclusion: Despite the presence of airway pathogens, these results confirm that heart-lung transplantation for cystic fibrosis leads to a pronounced improvement in lung function and good rehabilitation after surgery. The two main obstacles are the shortage of donor organs and the possibility of late deterioration in lung function with a progressive airflow obstruction.

We report the case of a 57-year-old woman who benefited from a complete revascularization of the heart, including a circumflex marginal coronary bypass grafting, through a right thoracotomy. This approach avoids sternal wound complications that can occur after high-dose mediastinal radiotherapy and omental flap reconstruction on the sternum.

We report three cases of fatal retrograde dissection of the aortic arch after exclusion-bypass with metal clamps according to Carpentier's thromboexclusion method. All three patients were male, aged 59, 66, and 73 years. Initial operative indications were chronic dissections in two cases and atheromatous aneurysm of the descending thoracic aorta in the other. Two of these patients were operated on in an emergency setting for a ruptured aneurysm. In all three cases, an extraanatomic bypass between the ascending aorta and abdominal aorta was performed as the first step: The proximal clamp was then placed distal to the origin of the left subclavian artery. Death occurred two hours, 12 hours, and eight days after operation, respectively. Autopsy revealed retrograde dissection initiating in the aortic arch and reaching the aortic ring as the cause of death. Pathological examination of aortic specimens confirmed that the dissections began just proximal to the site of clamping. To explain this complication, two etiologic factors, occurring either alone or together, have been postulated: postoperative hypertension and trauma to the aortic wall from the clamp.
