RESUMO

BACKGROUND: For cardiac surgery patients under chronic ß-blocker therapy, guidelines recommend their early postoperative reintroduction to decrease the incidence of postoperative atrial fibrillation. The authors hypothesized that the timing of ß-blocker reintroduction affects their effectiveness on the incidence of postoperative atrial fibrillation. METHODS: This multicenter prospective French cohort study included patients on ß-blockers (more than 30 days before surgery) in sinus rhythm without a pacemaker. The primary outcome, time sequence of ß-blocker reintroduction, was analyzed for 192 h after surgery. The secondary outcome, relationship between the occurrence of postoperative atrial fibrillation and timing of ß-blocker reintroduction, was analyzed based on pre- and intraoperative predictors (full and selected sets) according to landmark times (patients in whom atrial fibrillation occurred before a given landmark time were not analyzed). RESULTS: Of 663 patients, ß-blockers were reintroduced for 532 (80%) but for only 261 (39%) patients in the first 48 h after surgery. Median duration before reintroduction was 49.5 h (95% CI, 48 to 51.5 h). Postoperative atrial fibrillation or death (N = 4) occurred in 290 (44%) patients. After performing a landmark analysis to take into account the timing of ß-blocker reintroduction, the adjusted odds ratios (95% CI) for predictor full and selected (increased age, history of paroxysmal atrial fibrillation, and duration of aortic cross clamping) sets for the occurrence of postoperative atrial fibrillation were: adjusted odds ratio (full) = 0.87 (0.58 to 1.32; P = 0.517) and adjusted odds ratio (selected) = 0.84 (0.58 to 1.21; P = 0.338) at 48 h; adjusted odds ratio (full) = 0.64 (0.39 to 1.05; P = 0.076) and adjusted odds ratio (selected) = 0.58 (0.38 to 0.89; P = 0.013) at 72 h; adjusted odds ratio (full) = 0.58 (0.31 to 1.07; P = 0.079) and adjusted odds ratio (selected) = 0.53 (0.31 to 0.91; P = 0.021) at 96 h. CONCLUSIONS: ß-Blockers were reintroduced early (after less than 48 h) in fewer than half of the cardiac surgery patients. Reintroduction decreased postoperative atrial fibrillation occurrence only at later time points and only in the predictor selected set model. These results are an incentive to optimize (timing, doses, or titration) ß-blocker reintroduction after cardiac surgery.

RESUMO

BACKGROUND: Infectious complications are a major cause of morbidity and mortality after heart transplantation (HT). However, the epidemiology and outcomes of these infections in the recent population of adult heart transplant recipients have not been investigated. METHODS: We conducted a single-center retrospective study on infectious complications occurring within 180 days following HT on consecutive heart transplant recipients, from January 2011 to June 2015 at Bichat University Hospital in Paris, France. Risk factors for non-viral infections occurring within 8, 30 and 180 days after HT were investigated using competing risk analysis. RESULTS: Overall, 113 patients were included. Fifty-eight (51%) HTs were high-priority allocations. Twenty-eight (25%) patients had an extracorporeal membrane oxygenation (ECMO) support at the time of transplantation. Ninety-two (81%) patients developed at least one infection within 180 days after HT. Bacterial and fungal infections (n = 181 episodes) occurred in 80 (71%) patients. The most common bacterial and fungal infections were pneumonia (n = 95/181 episodes, 52%), followed by skin and soft tissue infections (n = 26/181, 14%). Multi-drug-resistant bacteria were responsible for infections in 21 (19%) patients. Viral infections were diagnosed in 44 (34%) patients, mostly Cytomegalovirus infection (n = 39, 34%). In multivariate subdistribution hazard model, prior cardiac surgery (subdistribution hazard ratio sHR = 2.7 [95% CI 1.5-4.6] p < 0.01) and epinephrine or norepinephrine at the time of HT (sHR = 2.3 [95% CI 1.1-5.2] p  = 0.04) were significantly associated with non-viral infections within 8 days after HT. Prior cardiac surgery (sHR = 2.5 [95% CI 1.4-4.4] p < 0.01), recipient age over 60 years (sHR = 2.0 [95% CI 1.2-3.3] p < 0.01) and ECMO following HT (sHR = 1.7 [95% CI 1.0-2.8] p = 0.04) were significantly associated with non-viral infection within 30 days after HT, as well as within 180 days after HT. CONCLUSION: This study confirmed the high rate of infections following HT. Recipient age, prior cardiac surgery and ECMO following HT were independent risk factors for early and late bacterial and fungal infections.

RESUMO

OBJECTIVES: Octogenarians considered for cardiac surgery encounter more complications than other patients. Postoperative complications raise the question of continuation of high-cost care for patients with limited life expectancy. Duration of hospitalization in intensive care after cardiac surgery may differ between octogenarians and other patients. The objectives were evaluating the mortality rate of octogenarians experiencing prolonged hospitalization in intensive care and defining the best cut-off for prolonged intensive care unit length of stay. DESIGN: A single-center observational study. SETTING: A postoperative surgical intensive care unit in a tertiary teaching hospital in Paris, France. PARTICIPANTS: All consecutive patients older than 80 years considered for aortic valve replacement for aortic stenosis were included. MEASUREMENTS AND MAIN RESULTS: Mortality rate was determined among patients experiencing prolonged stay in intensive care with organ failure and without organ failure. An ROC curve determined the optimal cut-off defining prolonged hospitalization in intensive care according to the occurrence of postoperative complications. Multivariate analysis determined risk factors for early death or prolonged intensive care stay. The optimal cut-off defining prolonged intensive care unit length of stay was 4 days. Low ventricular ejection fraction (odds ratio [OR] = 0.95; 95% confidence interval [CI] 0.96-0.83; p = 0.0016), coronary disease (OR = 2.34; 95% CI 1.19-4.85; p = 0.014), and need for catecholamine (OR = 2.79; 95% CI 1.33-5.88; p = 0.0068) were associated with eventful postoperative course. There was not a hospitalization duration beyond which the prognosis significantly worsened. CONCLUSIONS: Prolonged length of stay in ICU without organ failure is not associated with increased mortality. No specific duration of hospitalization in intensive care was associated with increased mortality. Continuation of care should be discussed on an individual basis.

RESUMO

Competitive flows syndrome result in severe regional hypoxemia when the deoxygenated flow from the native left ventricle (LV) competes with oxygenated flow from extracorporeal life support (ECLS) pump with potentially severe consequences for the cerebral and coronary circulations. Fast correction of hypoxemia could be obtained by decreasing native LV flow by infusion of a short-acting beta-blocker (esmolol). Our purpose was to retrospectively review the efficacy of esmolol in this situation and hypothesize on the potential mechanisms of action and the associated risks. This is a retrospective analysis of five clinical cases, who underwent lung transplantation and a femoro-femoral venoarterial (VA) ECLS. The patients presented severe hypoxemia (SpO2 < 85%) measured through photoplethysmography on a right hand finger. From the patients' medical records and anesthesia flowcharts, hemodynamic, right heart catheterization, echocardiography variables, and arterial blood gas results were noted before and after injection of esmolol. Mechanical ventilation and VA ECLS function variables were optimized and unchanged before and after esmolol injection. All patients had terminal respiratory failure with pulmonary hypertension and conserved LV systolic function. Immediately following esmolol injection (1.3 ± .7 mg/kg; mean ± 1 SD), SpO2 increased from 73% ± 12 to 95% ± 6; blood to arterial partial pressure in CO2 (PaCO2) decreased from 52 ± 18 to 35 ± 7 mmHg systolic pulmonary artery pressure decreased from 61 ± 8 to 50 ± 12 mmHg; the pulmonary artery oxygen saturation (SvO2); increased from 51% ± 24 to 77% ± 12; systemic arterial pressure or catecholamine requirements were unchanged. In conclusion, these results suggest that injection of esmolol allowed rapid correction of regional hypoxemia occurring during lung transplantation despite femoro-femoral VA ECLS. The mechanism is probably a decreased cardiac output of the native LV due to esmolol-induced negative inotropic and chronotropic effects without significant adverse effects on systemic tissue perfusion.

RESUMO

OBJECTIVES: The use of heparin exposes patients to heparin-induced thrombocytopenia, which is a challenging issue for both diagnosis and patient management. We sought to describe the clinical presentation, management and outcome of a series of patients diagnosed with heparin-induced thrombocytopenia after heart valve surgery. METHODS: All consecutive patients diagnosed with heparin-induced thrombocytopenia during the postoperative period of heart valve surgery over a 6-year period were prospectively enrolled in a single-centre registry. Clinical and biological data were collected. In-hospital and mid-term outcomes were assessed. Information regarding the occurrence of all medical events including death, recurrence of thromboembolic events and/or thrombocytopenia was collected. RESULTS: We identified 93 patients (incidence proportion = 2.8%). Most patients (82%) were asymptomatic with isolated thrombocytopenia at the time of diagnosis. The other main circumstance of diagnosis was the occurrence of thromboembolic events in 17 patients (6 strokes, 10 prosthetic valve thrombosis and 1 peripheral embolic event). The in-hospital mortality rate was 1%. No thrombolysis, interventional procedure or redo surgery was performed. Danaparoid sodium was used as heparin replacement therapy in most cases (96%) and leading to complete and uneventful thrombus resolution in all cases with only one possibly related major bleeding complication. During a mean follow-up of 36 ± 20 months, no patient presented recurrence of any heparin-induced thrombocytopenia-related complication. CONCLUSIONS: In this contemporary series of patients, heparin-induced thrombocytopenia incidence was low and isolated thrombocytopenia was the most frequent presentation. Conservative management with early diagnosis and substitutive anticoagulation therapy introduction was associated with a low rate of clinical events and a remarkably good outcome with a low mortality rate.

RESUMO

OBJECTIVE: Surgery for aortic stenosis in patients with thoracic radiation therapy is associated with high morbi-mortality. Trans-catheter aortic valve implantation (TAVI) represents an alternative but has never been studied in this population. We aimed to compare outcomes in radiation and matched control patients undergoing TAVI and to identify predictive factors of survival. METHODS: Between 2006 and 2011, 288 consecutive patients underwent TAVI in our institution, of whom 26 had previous chest radiation. They were matched 1:1 for age, sex and TAVI approach with controls. RESULTS: In both groups, median age was 73 years, 50% of patients were male and 15% had a transapical approach. Procedural success was 88% in the radiation group versus 100% in controls (p<0.001) and 30-day survival was 92% in both groups. Five-year survival was 33%±10% in the radiation group and 42%±11% in controls (p=0.26). In radiation patients, the main cause of death was respiratory insufficiency in 40%. We identified four independent predictive factors of death in the radiation group: extracardiac arteriopathy (p=0.002) and the absence of ß-blocker therapy (p=0.005) as preprocedural variables, and infectious complications (p=0.009) and a higher peak creatinine level (p=0.009) as postprocedural variables. In the radiation group, 89% of survivors were in New York Heart Association class I-II at last follow-up. CONCLUSIONS: Patients in the radiation group displayed high mortality rates although not significantly different from the controls. Respiratory failure was the main cause of death, emphasising the need for a careful pulmonary evaluation. Finally, we show a sustained improvement in functional results after TAVI in this population.

RESUMO

Tricuspid valve disease is mainly represented by tricuspid regurgitation (TR), which is a predictor of poor outcome. TR is usually secondary, caused by right ventricle pressure or volume overload, the leading cause being left-sided heart valve diseases. Tricuspid surgery for severe TR is recommended during left valve surgery, and consists of either a valve replacement or, most often, a tricuspid repair with or without prosthetic annuloplasty. When TR persists or worsens after left valvular surgery, redo isolated tricuspid surgery is associated with high mortality. In addition, a sizeable proportion of patients present with tricuspid surgery deterioration over time, and need a reintervention, which is associated with high morbi-mortality rates. In this context, and given the recent major breakthrough in the percutaneous treatment of aortic and mitral valve diseases, the tricuspid valve appears an appealing challenge, although it raises specific issues. The first applications of transcatheter techniques for tricuspid valve disease were valve-in-valve and valve-in-ring implantation for degenerated bioprosthesis or ring annuloplasty. Some concerns remain regarding prosthesis sizing, rapid ventricular pacing and the best approach, but these procedures appear to be safe and effective. More recently, bicuspidization using a transcatheter approach for the treatment of native tricuspid valve has been published, in two patients. Finally, other devices are in preclinical development.

RESUMO

BACKGROUND: Bleeding originating in the gastrointestinal (GI) tract is one of the most common adverse events after left ventricular assist device (LVAD) implantation. In these patients, GI bleeding appears to be the consequence of altered hemostasis on the one hand and alterations of the GI microvasculature on the other. CASE REPORT: We report the case of a patient who suffered repeated, severe GI bleeding early after implantation of a HeartMate II continuous-flow LVAD. RESULTS: After failure of conventional treatment strategies, GI bleeding was controlled using repeated transfusions of a purified von Willebrand factor (VWF) concentrate, almost devoid of Factor VIII (Wilfactin, LFB). No episodes of pump thrombosis were noted. Subsequent to VWF transfusions, we observed a progressive normalization of circulating vascular endothelial growth factor levels. CONCLUSIONS: Our data raise the possibility that, in addition to its hemostatic properties, transfusions of VWF might have acted as an antiangiogenic factor.

RESUMO

OBJECTIVES: The aims of this study were, first, to identify risk factors for microbiology-proven postoperative pneumonia after cardiac surgery and, second, to develop and validate a preoperative scoring system for the risk of postoperative pneumonia. DESIGN AND SETTING: A single-center cohort study. PATIENTS: All consecutive patients undergoing cardiac surgery between January 2006 and July 2011. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Multivariate analysis of risk factors for postoperative pneumonia was performed on data from patients operated between January 2006 and December 2008 (training set). External temporal validation was performed on data from patients operated between January 2009 and July 2011 (validation set). Preoperative variables identified in multivariate analysis of the training set were then used to develop a preoperative scoring system that was validated on the validation set. Postoperative pneumonia occurred in 174 of the 5,582 patients (3.1%; 95% CI, 2.7-3.6). Multivariate analysis identified four risk factors for postoperative pneumonia: age (odds ratio, 1.02; 95% CI, 1.01-1.03), chronic obstructive pulmonary disease (odds ratio, 2.97; 95% CI, 1.8-4.71), preoperative left ventricular ejection fraction (odds ratio, 0.98; 95% CI, 0.96-0.99), and the interaction between RBC transfusion during surgery and duration of cardiopulmonary bypass (odds ratio, 2.98; 95% CI, 1.96-4.54). A 6-point score including the three preoperative variables then defined two risk groups corresponding to postoperative pneumonia rates of 1.8% (score < 3) and 6.5% (score ≥ 3). CONCLUSION: Assessing preoperative risk factors for postoperative pneumonia with the proposed scoring system could help to implement a preventive policy in high-risk patients with a risk of postoperative pneumonia greater than 4% (i.e., patients with a score ≥ 3).

RESUMO

OBJECTIVES: Sternal wound infections occurring after cardiac surgery have a critical impact on morbidity, mortality and hospital costs. This study evaluated the efficacy of a gentamicin-collagen sponge in decreasing deep sternal-wound infections in high-risk cardiac surgery patients. METHODS: We conducted a quasi-experimental single-centre prospective cohort study in diabetic and/or overweight patients undergoing coronary-artery bypass surgery with bilateral internal mammary artery grafts. The end-point was the rate of reoperation for deep sternal wound infection. The period from January 2006 to October 2008, before the introduction of the gentamicin sponge, was compared with the period from November 2008 to December 2010. RESULTS: Of 552 patients (median body mass index, 31.5; 37.7% with diabetes requiring insulin), 68 (12.3%) had deep sternal wound infections. Reoperation for deep sternal wound infections occurred in 40/289 (13.8%) preintervention patients and 22/175 (12.6%) patients managed with the sponge. Independent risk factors were female sex and longer time on mechanical ventilation, but not use of the sponge (adjusted odds ratio, 0.95; 95% confidence interval, 0.52-1.73; P = 0.88). The group managed with the sponge had a higher proportion of gentamicin-resistant micro-organisms (21/27, 77.8%) compared with the other patients (23/56, 41.1%; P < 0.01). The median time to reoperation for wound infection was higher with the sponge (21 vs 17 days, P < 0.01). CONCLUSIONS: A gentamicin-collagen sponge was not effective in preventing deep sternal wound infections in high-risk patients. Our results suggest that a substantial proportion of wound contaminations occur after bypass surgery with bilateral internal mammary artery grafts.

RESUMO

AIMS: To describe the characteristics of coronary artery disease (CAD) in high-risk patients with aortic stenosis (AS), and its impact on indications for transcatheter aortic valve implantation (TAVI), and on outcomes. METHODS AND RESULTS: Of 240 patients referred for TAVI, 230 had documented CAD status. Mean age was 81.5±8 years. Hundred and forty-four (63%) had CAD. Compared to patients with no CAD, those with CAD had a higher risk of mortality (EuroSCORE: 31±18%, vs. 23±11%, p=0.004). Overall, 145 patients (63%) underwent TAVI, 31 (13%) surgery, and 54 (24%) medical treatment. No patient was denied intervention because of the CAD. CAD led to re-orientate one patient (0.4%) towards surgery. PCI was performed before TAVI in 11 (7%). Survival rates were respectively 90% and 85% in the CAD and non-CAD groups (p=0.37) at 30 days, and 76.4±5.4% and 70.6±6.8% (p=0.28) at 1-year. At follow-up, functional status was similar in both groups and no further revascularisation was needed. CONCLUSIONS: In high-risk patients referred for TAVI, CAD is frequent and associated with worse baseline characteristics. It has a limited impact on indications for TAVI. It seldom requires revascularisation and does not preclude satisfactory outcomes after TAVI.

RESUMO

OBJECTIVE: To describe differences in intra- and postoperative care between general (GA) and local/regional anesthesia (LRA) in consecutive high-risk patients with aortic stenosis who underwent transfemoral transcatheter aortic valve implantation (TAVI). DESIGN: A retrospective review of data collected in an institutional registry. SETTING: An academic hospital. PARTICIPANTS: One hundred twenty-five consecutive patients with severe aortic stenosis who underwent transfemoral TAVI. INTERVENTIONS: GA versus LRA followed by postoperative care. Complications were defined by pre-established criteria. MATERIAL AND METHODS: Consecutive patients referred for transfemoral TAVI between October 2006 and October 2010 initially underwent GA (n = 91) followed by LRA after March 2010 (n= 34). Results are presented as mean ± standard deviation or median (25-75 percentiles) as appropriate. GA and LRA TAVI patients had similar preoperative characteristics. LRA was associated with a significantly shorter procedure duration (LRA: 80 [67-102]; GA: 120 [90-140 minutes]; p < 0.001), hospital stay (LRA: 8.5 [7-14.5]; GA: 15.5 [10-24] days; p < 0.001), intraoperative requirements of catecholamines (LRA 23%; GA: 90% of patients; p < 0.001), and volume expansion (LRA: 11 [8-16]; GA: 22 [15-36] mL/kg; p < 0.001). There were significant differences in delta creatinine (day 1, preoperative creatinine values; LRA: 0 [-12 to 9]; GA: -15 (-25 to 2.9) µmol, p < 0.004). The frequency of any postoperative complications was 38% (LRA) and 77% (GA) (p = 0.11). Thirty-day mortality was 7% (GA) and 9% (LRA) (p = 0.9). CONCLUSIONS: This observational study suggests that LRA was associated with less intraoperative hemodynamic instability and significant shortening of the procedure and hospital stay. Changes in the anesthetic technique adapted to changes in TAVI interventional techniques and did not increase the rate of postoperative complications.

RESUMO

AIMS: To assess the results of percutaneous aortic balloon valvuloplasty (PABV) as a potential bridge to further intervention in patients referred for transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: Two hundred and fifty-three patients referred for TAVI were studied: 41 (16%) were considered transiently unsuitable for either aortic valve replacement (AVR) or TAVI and underwent PABV as a bridge to intervention. In the others, primary TAVI or AVR was performed in 140 cases, and medical therapy alone in 72.The overall population was at high risk: 82 ± 8 years, logistic EuroSCORE: 28 ± 16%, STS score: 16 ± 10%. There was no PABV-related death. Twenty-three patients underwent secondary TAVI (n=19) or AVR (n=4), 18 did not undergo further intervention. One and two year survival rates were respectively 94 ± 5% and 85 ± 10% after bridge PABV, and 33 ± 11 and 6 ± 5% after PABV alone. There was no difference in survival between the primary TAVI / AVR and bridge PABV (p=0.08), and between medical treatment and PABV alone (p=0.36). CONCLUSION: In high-risk patients with aortic stenosis and temporary contraindications to AVR or TAVI, PABV may be used as a bridge to intervention with good mid-term outcomes. In others, PABV can be safely used but is associated with a poor outcome.

RESUMO

OBJECTIVE: The aim of the present study was to assess the influence of preoperative statin therapy on postoperative mortality in high-risk patients after isolated valve surgery. DESIGN: An observational cohort study. SETTING: A 1,200-bed university hospital. PARTICIPANTS: All consecutive patients undergoing isolated nonemergent valve surgery with cardiopulmonary bypass between November 2005 and December 2007 were included. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: During the period, 772 consecutive patients underwent nonemergent isolated valve surgery. Among them, 430 were high cardiovascular risk (defined by patients with 2 or more cardiovascular risk factors). In the high-risk cardiovascular patients, statin pretreatment was administered in 222 patients (52%). In multivariate analysis, after adjustment with a propensity score analysis, preoperative statin therapy was associated with a significant reduction of postoperative mortality in patients with high risk (odds ratio = 0.41; 95% confidence interval, 0.17-0.97; p = 0.04). Low left ventricular ejection fraction and elevated pulmonary artery pressure also were independently associated with increased postoperative mortality. By contrast, in the low-risk patient group, few patients received preoperative statin therapy (7%). CONCLUSIONS: This study suggests that preoperative statin therapy may have a potential beneficial effect on postoperative mortality after isolated cardiac valve surgery in high-risk cardiovascular patients.

RESUMO

BACKGROUND AND OBJECTIVE: Although results of cardiac surgery are improving, octogenarians have a higher procedure-related mortality and more complications with increased length of stay in ICU. Consequently, careful evaluation of perioperative risk seems necessary. The aims of our study were to assess and compare the performances of EuroSCORE and CARE score in the prediction of perioperative mortality among octogenarians undergoing aortic valve replacement for aortic stenosis and to compare these predictive performances with those obtained in younger patients. METHODS: This retrospective study included all consecutive patients undergoing cardiac surgery in our institution between November 2005 and December 2007. For each patient, risk assessment for mortality was performed using logistic EuroSCORE, additive EuroSCORE and CARE score. The main outcome measure was early postoperative mortality. Predictive performances of these scores were assessed by calibration and discrimination using goodness-of-fit test and area under the receiver operating characteristic curve, respectively. RESULTS: During this 2-year period, we studied 2117 patients, among whom 134/211 octogenarians and 335/1906 nonoctogenarians underwent an aortic valve replacement for aortic stenosis. When considering patients with aortic stenosis, discrimination was poor in octogenarians and the difference from nonoctogenarians was significant for each score (0.58, 0.59 and 0.56 vs. 0.82, 0.81 and 0.77 for additive EuroSCORE, logistic EuroSCORE and CARE score in octogenarians and nonoctogenarians, respectively, P < 0.05). Moreover, in the whole cohort, logistic EuroSCORE significantly overestimated mortality among octogenarians. CONCLUSION: Predictive performances of these scores are poor in octogenarians undergoing cardiac surgery, especially aortic valve replacement. Risk assessment and therapeutic decisions in octogenarians should not be made with these scoring systems alone.
