New French heart allocation system: Comparison with Eurotransplant and US allocation systems.

Graft allocation rules for heart transplantation are necessary because of the shortage of heart donors, resulting in high waitlist mortality. The Agence de la biomédecine is the agency in charge of the organ allocation system in France. Assessment of the 2004 urgency-based allocation system identified challenging limitations. A new system based on a score ranking all candidates was implemented in January 2018. In the revised system, medical urgency is defined according to candidate characteristics rather than the treatment modalities, and an interplay between urgency, donor-recipient matching, and geographic sharing was introduced. In this article, we describe in detail the new allocation system and compare these allocation rules to Eurotransplant and US allocation policies.

Management of end-stage heart failure patients with or without ventricular assist device: an observational comparison of clinical and economic outcomes.

OBJECTIVES: Heart transplantation (HT) and ventricular assist devices (VAD) for the management of end-stage heart failure have not been directly compared. We compare the outcomes and use of resources with these 2 strategies in 2 European countries with different allocation systems. METHODS: We studied 83 patients managed by VAD as the first option in Bad Oeynhausen, Germany (Group I) and 141 managed with either HT or medical therapy, as the first option, in Paris, France (Group II). The primary end-point was 2-year survival. Kaplan-Meier analyses were performed after the application of propensity score weights to mitigate the effects of non-random group assignment. The secondary end-points were resource utilization and costs. Subgroup analyses were performed for patients undergoing HT and patients treated with inotropes at the enrolment time. RESULTS: The Group I patients were more severely ill and haemodynamically compromised, and 28% subsequently underwent HT vs 55% primary HT in Group II, P < 0.001. The adjusted probability of survival was 44% in Group I vs 70% in Group II, P <0.0001. The mean cumulated 2-year costs were €281 361 ± 156 223 in Group I and €47 638 ± 35 061 in Group II, P < 0.0001. Among patients who underwent HT, the adjusted probability of survival in Group I (n = 23) versus Group II (n = 78) was 76% versus 68%, respectively (0.09), though it differed in the inotrope-treated subgroups (77% in Group I vs 67% in Group II, P = 0.04). CONCLUSIONS: HT should remain the first option for end-stage heart failure patients, associated with improved outcomes and better cost-effectiveness profile. VAD devices represent an option when transplant is not possible or when patient presentation is not optimal.

Optimizing the management of acute coronary syndromes in sub-Saharan Africa: A statement from the AFRICARDIO 2015 Consensus Team.

BACKGROUND: Whereas the coronary artery disease death rate has declined in high-income countries, the incidence of acute coronary syndromes (ACS) is increasing in sub-Saharan Africa, where their management remains a challenge. AIM: To propose a consensus statement to optimize management of ACS in sub-Saharan Africa on the basis of realistic considerations. METHODS: The AFRICARDIO-2 conference (Yamoussoukro, May 2015) reviewed the ongoing features of ACS in 10 sub-Saharan countries (Benin, Burkina-Faso, Congo-Brazzaville, Guinea, Ivory Coast, Mali, Mauritania, Niger, Senegal, Togo), and analysed whether improvements in strategies and policies may be expected using readily available healthcare facilities. RESULTS: The outcome of patients with ACS is affected by clearly identified factors, including: delay to reaching first medical contact, achieving effective hospital transportation, increased time from symptom onset to reperfusion therapy, limited primary emergency facilities (especially in rural areas) and emergency medical service (EMS) prehospital management, and hence limited numbers of patients eligible for myocardial reperfusion (thrombolytic therapy and/or percutaneous coronary intervention [PCI]). With only five catheterization laboratories in the 10 participating countries, PCI rates are very low. However, in recent years, catheterization laboratories have been built in referral cardiology departments in large African towns (Abidjan and Dakar). Improvements in patient care and outcomes should target limited but selected objectives: increasing awareness and recognition of ACS symptoms; education of rural-based healthcare professionals; and developing and managing a network between first-line healthcare facilities in rural areas or small cities, emergency rooms in larger towns, the EMS, hospital-based cardiology departments and catheterization laboratories. CONCLUSION: Faced with the increasing prevalence of ACS in sub-Saharan Africa, healthcare policies should be developed to overcome the multiple shortcomings blunting optimal management. European and/or North American management guidelines should be adapted to African specificities. Our consensus statement aims to optimize patient management on the basis of realistic considerations, given the healthcare facilities, organizations and few cardiology teams that are available.

Predictive factors of early mortality after transcatheter aortic valve implantation: individual risk assessment using a simple score.

OBJECTIVE: Decision making for intervention in symptomatic aortic stenosis should balance the risks of surgery and of transcatheter aortic valve implantation (TAVI). We identified the factors associated with early mortality after TAVI and aimed to develop and validate a simple risk score. METHODS: A population of 3833 consecutive patients was randomly split into two cohorts comprising 2552 and 1281 patients, used respectively to develop and validate a scoring system predicting 30-day or in-hospital mortality. RESULTS: TAVI was performed using the Edwards Sapien prosthesis in 2551 (66.8%) patients and the Medtronic Corevalve in 1270 (33.2%). Approach was transfemoral in 2801 (73.4%) patients, transapical in 678 (17.8%), subclavian in 219 (5.7%) and other in 117 (3.1%). Early mortality was 10.0% (382 patients). A multivariate logistic model identified the following predictive factors of early mortality: age ≥90 years, body mass index <30 Kg/m(2), New York Heart Association class IV, pulmonary hypertension, critical haemodynamic state, ≥2 pulmonary oedemas during the last year, respiratory insufficiency, dialysis and transapical or other (transaortic and transcarotid) approaches. A 21-point predictive score was derived. C-index was 0.67 for the score in the development cohort and 0.59 in the validation cohort. There was a good concordance between predicted and observed 30-day mortality rates in the development and validation cohorts. CONCLUSIONS: Early mortality after TAVI is mainly related to age, the severity of symptoms, comorbidities and transapical approach. A simple score can be used to predict early mortality after TAVI. The moderate discrimination is however a limitation for the accurate identification of high-risk patients.

Outcomes, long-term quality of life, and psychologic assessment of fulminant myocarditis patients rescued by mechanical circulatory support.

OBJECTIVE: Myocarditis is a rare disease that may progress rapidly to refractory cardiogenic shock and death. In such situations, emergent initiation of mechanical circulatory assistance is the only therapeutic option to rescue these dying patients. This study was designed to evaluate the outcomes, health-related quality of life and frequencies of anxiety, depression and posttraumatic stress disorder symptoms in fulminant myocarditis patients rescued by mechanical circulatory assistance, since these major components of outcome evaluation after serious illnesses have not yet been assessed in this setting. DESIGN: A retrospective, single-center, observational study and a cross-sectional survey to assess health-related quality of life by the Short Form-36 questionnaire and frequencies of anxiety, depression and posttraumatic stress disorder symptoms by the Hospital Anxiety and Depression Scale and the Impact of Event Scale, respectively. SETTING: An 18-bed tertiary intensive care unit in a university hospital. PATIENTS: We analyzed the short- and long-term outcomes of 41 patients hospitalized at our institution between 2003 and 2009 and who received either a Thoratec BiVAD (Thoratec, Pleasanton, CA) (n = 6) or extracorporeal membrane oxygenation (n = 35) to combat refractory cardiogenic shock due to fulminant myocarditis. MEASUREMENTS AND MAIN RESULTS: Intensive care unit survival was 68%, and four (10%) patients underwent heart transplantation. Independent predictors of in-intensive care unit death were Simplified Acute Physiology Score II ≥56 (odds ratio = 10.23) and troponin Ic ≥12 µg/L (odds ratio = 7.49) at admission. Complete follow-up (median, 525 days) was available for 26 of 28 survivors. Compared to age- and sex-matched controls, Short Form-36 evaluation of health-related quality of life revealed satisfactory mental health and vitality but persistent physical and psychosocial-related difficulties. Lastly, anxiety, depression, and/or posttraumatic stress disorder symptoms were reported by 38%, 27% and 27% of the patients, respectively. CONCLUSIONS: Mechanical circulatory assistance rescued 68% of patients with refractory circulatory failure due to fulminant myocarditis. Greater disease severity and higher troponin Ic levels at extracorporeal membrane oxygenation initiation predicted poorer prognosis. Because up to one-third of the patients reported anxiety, depression, and/or posttraumatic stress disorder symptoms, strategies aimed at attenuating their emotional and psychologic distress might significantly improve their long-lasting well-being.
