RESUMO
Re-transplantation is the preferred treatment for patients with chronic heart transplant failure. If re-transplantation is not a viable option due to the patient's comorbidities, left ventricle assist device can be used as the destination treatment. An interdisciplinary approach with thorough follow-up can help in the early detection and treatment of complications associated with LVAD.

Acute type A aortic dissection (ATAAD) is a life-threatening event that requires immediate surgical treatment. Improvements in surgical treatment, graft technology, organ protection and imaging techniques have led to improved clinical outcomes. Individualized treatment concepts have emerged based on more advanced planning tools that allow for a tailored approach even in complex situations such as multi-level malperfusion. This review provides an overview of the current surgical treatment of ATAAD, focusing on new disease classifications, preoperative computed tomography angiography (CTA) assessment, new prosthesis and stent technologies, and organ-protection strategies.

OBJECTIVES: This study aimed to develop a patient-centred approach to the burden of acute type A aortic dissection (ATAAD) through modelling. The main objective was to identify potential improvements in managing this life-threatening cardiovascular condition and to provide evidence-based recommendations to optimise outcomes. DESIGN: We developed a predictive model along patient pathways to estimate the burden of ATAAD through the years of life lost (YLLs) metric. The model was created based on a systematic review of the literature and was parameterised using demographic data from the German healthcare environment. The model was designed to allow interactive simulation of different scenarios resulting from changes in key impact factors. SETTING: The study was conducted using data from the German healthcare environment and results from the literature review. PARTICIPANTS: The study included a comprehensive modelling of ATAAD cases in Germany but did not directly involve participants. INTERVENTIONS: There were no specific interventions applied in this study based on the modelling design. PRIMARY AND SECONDARY OUTCOME MEASURES: The single outcome measure was the estimation of YLL due to ATAAD in Germany. RESULTS: Our model estimated 102 791 YLL per year for ATAAD in Germany, with 62 432 and 40 359 YLL for men and women, respectively. Modelling an improved care setting yielded 93 191 YLL or 9.3% less YLL compared with the current standard while a worst-case scenario resulted in 113 023 or 10.0% more YLL. The model is accessible at https://acuteaorticdissection.com/ to estimate custom scenarios. CONCLUSIONS: Our study provides an evidence-based approach to estimating the burden of ATAAD and identifying potential improvements in the management of pathways. This approach can be used by healthcare decision-makers to inform policy changes aimed at optimising patient outcomes. By considering patient-centred approaches in any healthcare environment, the model has the potential to improve efficient care for patients suffering from ATAAD.

OBJECTIVES: The objective of the present study was to model the effects of a reduced number of treatment centres for acute type A aortic dissection on preclinical transportation distance and time. We examined whether treatment in selected centres in Germany would be implementable with respect to time to treatment. METHODS: For our transportation model, the number of aortic dissections and respective mean annual volume were collected from the annual quality reports (2015-2017) of all German cardiac surgery centres (n = 76). For each German postal code, the fastest and shortest routes to the nearest centre were calculated using Google Maps. Furthermore, we analysed data from the German Federal Statistical Office from January 2005 to December 2015 to identify all surgically treated patients with acute type A aortic dissection (n = 14 102) and examined the relationship between in-hospital mortality and mean annual volume of medical centres. RESULTS: Our simulation showed a median transportation distance of 27.13 km and transportation time of 35.78 min for 76 centres. Doubling the transportation time (70 min) would allow providing appropriate care with only 12 medical centres. Therefore, a mean annual volume of >25 should be obtained. High mean annual volume was associated with significantly lower in-hospital mortality rates (P < 0.001). A significantly lower mortality rate of 14% was observed (P < 0.001) if a mean annual volume of 30 was achieved. CONCLUSIONS: Operationalizing the volume-outcome relationship with fewer but larger medical centres results in lower mortality, which outweighs the disadvantage of longer transportation time.

OBJECTIVES: Cardiopulmonary resuscitation (CPR) aggravates the pre-existing dismal prognosis of patients suffering from acute type A aortic dissection (ATAAD). We aimed to identify factors affecting survival and outcome in ATAAD patients requiring CPR at presentation at 2 European aortic centres. METHODS: Data on 112 surgical candidates and undergoing preoperative CPR were retrospectively evaluated. Patients were divided into 2 groups according to 30-day mortality. A multivariable model identified predictors for 30-day mortality. RESULTS: Preoperative death occurred in 23 patients (20.5%). In the remaining 89 surgical patients (79.5%) circulatory arrest time (41 ± 20 min in 30-day non-survivors vs 30 ± 13 min in 30-day survivor, P = 0.003) as well as cardiopulmonary bypass time (320 ± 132 min in 30-day non-survivors vs 252 ± 140 min in 30-day survivor, P = 0.020) time was significantly longer in patients with worse outcome. Thirty-day mortality of the total cohort was 61.6% (n = 69) with cardiac failure in 48% and aortic rupture or haemorrhagic shock (28%) as predominant reasons of death. Age [odds ratio (OR) 1.04, 95% confidence interval (CI) 1.01-1.09, P = 0.034], preoperative coronary (OR 3.42, 95% CI 1.34-9.26, p = 0.012) and spinal malperfusion (OR 12.49, 95% CI 1.83-225.02, P = 0.028) emerged as independent predictors for 30-day mortality while CPR due to tamponade was associated with improved early survival (OR 0.29, 95% CI 0.091-0.81, P = 0.023). CONCLUSIONS: Assessment of underlying cause for CPR is mandatory. Pericardial tamponade, rapidly resolved with pericardial drainage, is a predictor for improved survival, while age and presence of coronary and spinal malperfusion are associated with dismal outcome in this high-risk patient group.

Coagulopathy is common in patients undergoing thoracic aortic repair for Stanford type A aortic dissection. Non-critical administration of blood products may adversely affect the outcome. It is therefore important to be familiar with the pathologic conditions that lead to coagulopathy in complex cardiac surgery. Adequate care of these patients includes the collection of the medical history regarding the use of antithrombotic and anticoagulant drugs, and a sophisticated diagnosis of the coagulopathy with viscoelastic testing and subsequently adapted coagulation therapy with labile and stable blood products. In addition to the above-mentioned measures, intraoperative blood conservation measures as well as good interdisciplinary coordination and communication contribute to a successful hemostatic management strategy.
RESUMO
OBJECTIVES: The aim of this study is to investigate the outcome of elderly patients with surgically treated acute type A aortic dissection (ATAAD) complicated by malperfusion. METHODS: Patients ≥70 years old who underwent surgical treatment for ATAAD between January 2000 and December 2020 were enrolled in this study and stratified by their specific Penn Classification into 4 different subgroups, where Penn Abc was defined as multilevel malperfusion. Short- and long-term outcomes were investigated. Multivariable binary logistic regression was performed to identify risk factors for 1-year mortality. RESULTS: Four hundred elderly patients underwent surgical treatment for ATAAD. A total of 204 (51%) patients had no evidence of malperfusion (Penn Aa), 106 (26.5%) had localized organic malperfusion (Penn Ab), 44 (11%) patients had systemic malperfusion (Penn Ac) and 46 (11.5%) suffered from multilevel malperfusion (Penn Abc). For the latter, in-hospital mortality was 70% (P < 0.001). Age (P < 0.006) and multilevel malperfusion (P < 0.001) were independent risk factors for 1-year mortality. Patients with multilevel malperfusion showed the worst 1-year survival (P < 0.001). In the case of Penn Aa, in-hospital mortality was 13% (P < 0.001). CONCLUSIONS: Surgery may lead to satisfactory results in the absence of malperfusion, even in octogenarians. Elderly patients with multilevel malperfusion show very poor surgical outcome. In these patients, the decision for surgery should be taken with caution. Operation, if performed, should be carried out by experienced teams only.

OBJECTIVES: The aim of this study was to externally validate a lab-based risk score (lactate, creatinine, aspartate aminotransferase, alanine aminotransferase or bilirubin) by Ghoreishi et al. to predict perioperative mortality in patients undergoing surgical repair for acute type A aortic dissection. METHODS: The risk score to predict operative mortality was applied to a large and homogenous validation cohort that consisted of 632 patients undergoing surgery for acute type A aortic dissection in 2 centres. Multivariable regression analysis was performed to determine the impact on survival. Receiver operating characteristics with deduced area under the curve were used to assess the ability to predict perioperative mortality. RESULTS: A total of 632 patients (54% male, mean age 62 ± 14 years) were assigned to 3 different risk groups according to the calculated mortality score [low risk <7 (31.2%), moderate risk 7-20 (36.1%) and high >20 (32.7%)]. Perioperative mortality was 8% in the low-risk group, 10% in the moderate-risk group and 24% in the high-risk group (P < 0.0001). Receiver operating characteristic analysis of this new score revealed an area under the curve of 0.69 with adequate calibration. In addition, multivariable analysis revealed an independet assocation with perioperative mortality (odds ratio 1.509; 95% confidence interval 1.042-2.185). While overall survival differed between the risk groups (P < 0.0001), the score does not serve as an independent predictor of long-term mortality when adjusted for relevant covariates. CONCLUSIONS: The external validation process confirmed that a newly proposed risk score offers clinicians a helpful and reliable tool to improve the preoperative risk assessment of acute type A aortic dissection patients based on easily accessible and broadly available laboratory parameters.

AIMS: The aim of this study was to compare discrepancies between diagnosed and autopsied causes of death in 1,112 hospital autopsies and to determine the factors causing this discrepancies. METHODS: 1,112 hospital autopsies between 2010 and 2013 were retrospectively studied. Ante-mortem diagnoses were compared to causes of death as determined by autopsy. Clinical diagnoses were extracted from the autopsy request form, and post-mortem diagnoses were assessed from respective autopsy reports. Variables, such as sex, age, Body Mass Index, category of disease, duration of hospital stay and new-borns were studied in comparison to discrepancy. P-values were derived from the Mann-Whitney U test for the constant features and chi-2 test, p-values < 0,05 were considered significant. RESULTS: 73.9% (n = 822) patients showed no discrepancy between autopsy and clinical diagnosis. The duration of hospitalisation (6 vs. 9 days) and diseases of the cardiovascular system (61.7%) had a significant impact on discrepancies. CONCLUSION: Age, cardiovascular diseases and duration of hospital stay significantly affect discrepancies in ante- and post-mortem diagnoses.

INTRODUCTION: Cocaine use is known to be associated with an increased risk for vascular diseases. It is likely to trigger or increase the risk for an aortic dissection. We conducted an analysis of 45 cases of cocaine-related aortic dissection to further characterize the clinical features and outcomes of this patient cohort. METHODS: Our study cohort of 45 patients consisted of 11 cases from our institutional database and 34 published case reports. RESULTS: The observed cases of acute aortic dissection related to cocaine use showed a high proportion of young (41.3±8.67 years) and male (88.9%) patients. Most of the cases (75%) were classified as Stanford type A. Also, in 75% of the cases, cocaine use was prevalent for more than one year. Median time from last cocaine use to onset of symptoms was one hour. In-hospital mortality was 21.4%, while additional 11.9% of the cases died before arriving at the hospital. CONCLUSION: Acute aortic dissection related to cocaine use occurs in predominantly young male patients and has a dismal outcome when compared to all comer series.

BACKGROUND: Acute type A aortic dissection requires immediate surgical treatment, but the correct diagnosis is often delayed. This study aimed to analyse how initial misdiagnosis affected the time intervals before surgical treatment, symptoms associated with correct or incorrect initial diagnosis and the potential of the Aortic Dissection Detection Risk Score to improve the sensitivity of initial diagnosis. METHODS: We conducted a retrospective analysis of 350 patients with acute type A aortic dissection. Patients were divided into two groups: initial misdiagnosis (group 0) and correct initial diagnosis of acute type A aortic dissection (group 1). Symptoms were analysed as predictors for the correct or incorrect initial diagnosis by multivariate analysis. Based on these findings, the Aortic Dissection Detection Risk Score was calculated retrospectively; a result ⩾2 was defined as a positive score. RESULTS: The early suspicion of aortic dissection significantly shortened the median time from pain to surgical correction from 8.6 h in patients with an initial misdiagnosis to 5.5 h in patients with the correct initial diagnosis (p<0.001). Of all acute type A aortic dissection patients, 49% had a positive Aortic Dissection Detection Risk Score. Of all initial misdiagnosed patients, 41% had a positive score (⩾2). The presence of lumbar pain (p<0.001), any paresis (p=0.037) and sweating (p=0.042) was more likely to lead to the correct initial diagnosis. CONCLUSION: An early consideration of acute aortic dissection may reduce the delay of surgical care. The suggested Aortic Dissection Detection Risk Score may be a useful tool to improve the preclinical assessment.

Due to the symptoms, patients with acute type A aortic dissection are first seen by the ambulance service and diagnosed at the emergency department. How often an aortic dissection occurs in an emergency department per year has been studied. The incidence in the emergency department may be used as a quality marker of differential diagnostics of acute chest pain. A multi-institutional retrospective study with the municipal Berlin hospital chain Vivantes and its Department of Pathology and the Charité - University Medicine Berlin was performed. From the Berlin Hospital Society, the annual numbers of publicly insured emergency patients were obtained. Between 2006 and 2016, 631 aortic dissections were identified. The total number of patients treated in the emergency departments (n = 12,790,577) was used to calculate the "emergency department incidence." The autopsy data from six clinics allowed an estimate on how many acute type A aortic dissections remained undetected. Across all Berlin hospitals, the emergency department incidence of acute type A aortic dissection was 5.24 cases in 100,000 patients per year. In tertiary referral hospitals and, particularly, in university hospitals the respective incidences were markedly higher (6.7 and 12.4, respectively). Based on the autopsy results, about 50% of the acute type A aortic dissection may remain undetected, which would double the reported incidences. Among different hospital types the emergency department incidences of acute type A aortic dissection vary between 5.93/100,000 and 24.92/100,000.
