A new insight into superacute care for type A acute aortic dissection in the Tokyo Acute Aortic Super Network. J Thorac Cardiovasc Surg 2024; 167:41-51.e4. [PMID: 37659462 DOI: 10.1016/j.jtcvs.2023.08.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 08/20/2023] [Accepted: 08/22/2023] [Indexed: 09/04/2023]
Abstract
OBJECTIVE To determine the status of type A acute aortic dissection using the Tokyo Acute Aortic Super Network. METHODS Data of 6283 patients with acute aortic dissection between 2015 and 2019 were collected. Data of 3303 patients with type A acute aortic dissection were extracted for analysis. RESULTS Overall, 51.0% of patients were nondirect admissions. On arrival, 23.1% of patients were in shock, 10.0% in cardiopulmonary arrest, and 11.8% in deep coma or coma. Overall, 9.8% of patients were assessed as untreatable. Of 2979 treatable patients, 18.3% underwent medical treatment, whereas 80.7% underwent surgery (open [78.8%], endovascular [1.9%], and peripheral [1.1%] repair). The early mortality rate was 20.5%, including untreatable cases. Among treatable patients, in-hospital mortality rates were 8.6% for open repair, 10.7% for endovascular repair, and 25.3% for medical treatment. Advanced age, preoperative comorbidities, classical dissection, and medical treatment were risk factors for in-hospital mortality. Nondirect admission did not cause increased deaths. The mortality rates were high during the superacute phase following symptom onset. CONCLUSIONS This study demonstrated current practices in the emergency care of type A acute aortic dissection via the Tokyo Acute Aortic Super Network system, specifically a high rate of untreatable or inoperable cases and favorable outcomes in patients undergoing surgical treatment. High mortality rates were observed during the super acute phase after symptom onset or hospital arrival.

Abstract
Background Sex differences in the clinical presentation and outcomes of DeBakey type I/II (Stanford type A) acute aortic dissection (AAD) remain unclear. Objectives The authors aimed to determine the impact of sex on the clinical presentation and in-hospital outcomes of surgically or medically treated patients with type I/II AAD. Methods We studied 3,089 patients with type I/II AAD enrolled in multicenter Japanese registry between 2013 and 2018. The patients were divided into 2 treatment groups: surgical and medical. Multivariable logistic regression was used to examine the association between sex and in-hospital mortality. Results In the entire cohort, women were older and more likely to have hyperlipidemia, previous stroke, altered consciousness, and shock/hypotension at presentation than men. Women had higher proportions of intramural hematomas and type II dissections than men. In the surgical group (n = 2,543), men had higher rates of preoperative end-organ malperfusion (P = 0.003) and in-hospital mortality (P = 0.002) than women. Multivariable analysis revealed that male sex was associated with higher in-hospital mortality after surgery (OR: 1.71; 95% CI: 1.24-2.35; P < 0.001). In the medical group (n = 546), women were older and had higher rates of cardiac tamponade (P = 0.004) and in-hospital mortality (P = 0.039) than men; no significant association between sex and in-hospital mortality was found after multivariable adjustment (OR: 0.95; 95% CI: 0.56-1.59; P = 0.832). Conclusions Male sex was associated with higher in-hospital mortality for type I/II AAD in the surgical group but not in the medical group. Further research is needed to understand the mechanisms responsible for worse surgical outcomes in men.

Abstract
BACKGROUND In acute aortic dissection, weekend admissions are reported to be associated with increased mortality compared with weekday admissions. OBJECTIVE This study aimed to determine whether patients with acute type A aortic dissection (ATAAD) admitted on weekends had higher in-hospital mortality than those admitted on weekdays in the Tokyo metropolitan area, where we developed a patient-transfer system for aortic dissection. METHODS Data were collected during the first year after our transfer system began (cohort I) and in the subsequent years from 2013 to 2015 (cohort II). RESULTS We studied 2,339 patients (500 in cohort I; 1,839 in cohort II) with ATAAD. Patients with weekend admissions had higher in-hospital mortality than those with weekday admissions in cohort I. In association with increased interfacility transfer during weekends and reduced mortality at non-high-volume centers, the in-hospital mortality in the weekend group improved from 37.2% in cohort I to 22.2% in cohort II (P < 0.001). After inverse probability weighting adjustment, weekend admission was associated with higher in-hospital mortality in cohort I (odds ratio: 2.28; 95% confidence interval: 1.48 to 3.52; P < 0.001), but not in cohort II (odds ratio: 0.96; 95% confidence interval: 0.75 to 1.22; P = 0.731). On multivariable analyses, weekend admission was associated with higher in-hospital mortality in combined cohort I+II; the associations between weekend admission and mortality were not significant in cohort II. CONCLUSIONS We found a significant reduction in in-hospital mortality in patients with weekend admissions for ATAAD. No mortality difference between weekend and weekday admissions was observed in the later years of the study.

Abstract
Background The association between female sex and poor outcomes following surgery for type A acute aortic dissection has been reported; however, sex‐related differences in clinical features and in‐hospital outcomes of type B acute aortic dissection, including classic aortic dissection and intramural hematoma, remain to be elucidated. Methods and Results We studied 2372 patients with type B acute aortic dissection who were enrolled in the Tokyo Acute Aortic Super‐Network Registry. There were fewer and older women than men (median age [interquartile range]: 76 years [66–84 years], n=695 versus 68 years [57–77 years], n=1677; P<0.001). Women presented to the aortic centers later than men. Women had a higher proportion of intramural hematoma (63.7% versus 53.7%, P<0.001), were medically managed more frequently (90.9% versus 86.3%, P=0.002), and had less end‐organ malperfusion (2.4% versus 5.7%, P<0.001) and higher in‐hospital mortality (5.3% versus 2.7%, P=0.002) than men. In multivariable analysis, age (per year, odds ratio [OR], 1.06 [95% CI, 1.03–1.08]; P<0.001), hyperlipidemia (OR, 2.09 [95% CI, 1.13–3.88]; P=0.019), painlessness (OR, 2.59 [95% CI, 1.14–5.89]; P=0.023), shock/hypotension (OR, 2.93 [95% CI, 1.21–7.11]; P=0.017), non–intramural hematoma (OR, 2.31 [95% CI, 1.32–4.05]; P=0.004), aortic rupture (OR, 26.6 [95% CI, 14.1–50.0]; P<0.001), and end‐organ malperfusion (OR, 4.61 [95% CI, 2.11–10.1]; P<0.001) were associated with higher in‐hospital mortality, but was not female sex (OR, 1.67 [95% CI, 0.96–2.91]; P=0.072). Conclusions Women affected with type B acute aortic dissection were older and had more intramural hematoma, a lower incidence of end‐organ malperfusion, and higher in‐hospital mortality than men. However, female sex was not associated with in‐hospital mortality after multivariable adjustment.

Abstract
Aortic calcification in the tunica media is correlated with aortic stiffness, elastin degradation, and wall shear stress. The study aim was to determine if aortic calcifications influence disease progression in patients with acute type A aortic dissection (ATAAD). We retrospectively reviewed a total of 103 consecutive patients who had undergone surgery for ATAAD at our institution between January 2009 and December 2019. Of these, 85 patients who had preoperatively undergone plain computed tomography angiography (CTA) for evaluation of their aortic calcification were included. Moreover, we assessed the progression of aortic dissection after surgery via postoperative CTA. Using a classification and regression tree to identify aortic Agatston score thresholds predictive of disease progression, the patients were classified into high-score (Agatston score ≥ 3344; n = 36) and low-score (<3344; n = 49) groups. Correlations between aortic Agatston scores and CTA variables were assessed. Higher aortic Agatston scores were significantly correlated with the smaller distal extent of aortic dissection (p < 0.001), larger true lumen areas of the ascending (p = 0.009) and descending aorta (p = 0.002), and smaller false lumen areas of the descending aorta (p = 0.028). Patients in the high-score group were more likely to have DeBakey type II dissection (p = 0.001) and false lumen thrombosis (p = 0.027) than those in the low-score group, thereby confirming the correlations. Aortic dissection in the high-score group was significantly less distally extended (p < 0.001). A higher aortic Agatston score correlates with the larger true lumen area of the ascending and descending aorta and the less distal progression of aortic dissection in patients with ATAAD. Interestingly, the findings before and after surgery were consistent. Hence, aortic Agatston scores are associated with aortic dissection progression and may help predict postoperative residual dissected aorta remodeling.

Abstract
OBJECTIVES To determine whether aortic enlargement in 2 weeks in patients with type B acute aortic syndrome is associated with aorta-related adverse events. METHODS This retrospective, single-center study included 183 patients who were diagnosed with uncomplicated type B acute aortic syndrome (classic aortic dissection and intramural hematoma) between 2010 and 2019 and had follow-up computed tomography at second or third week. Aortic diameter was measured at admission and at predischarge follow-up. Aorta-related adverse events were defined by a composite of aortic rupture, surgical or endovascular aortic repair, redissection, severe intestinal malperfusion, and aortic enlargement. RESULTS The patients whose aortic diameter enlarged ≥2 mm but <5 mm in 2 weeks were categorized as moderate aortic enlargement group. During follow-up, 51 patients (28%) had aorta-related adverse events and 36 patients (20%) had moderate aortic enlargement. Patients with moderate aortic enlargement showed lower aorta-related event-free survival rates than those without moderate enlargement (48 ± 9% vs 90 ± 3% at 1 year, P < .001). On multivariable analysis, moderate aortic enlargement (subhazard ratio, 3.64; 95% confidence interval, 2.08-6.35; P < .001) and aortic diameter ≥40 mm at admission (subhazard ratio, 2.96; 95% confidence interval, 1.60-5.48; P < .001) were associated with aorta-related adverse events. CONCLUSIONS Moderate aortic enlargement in 2 weeks is a significant risk factor of aorta-related adverse events in patients with uncomplicated type B acute aortic syndrome. Patients with moderate aortic enlargement should be followed up carefully and may be candidates for subsequent endovascular treatment.

Abstract
Acute aortic dissection (AAD), one of the fatal diseases observed at the department of vascular surgery, is associated with a great mortality rate at the early stage. Ceruloplasmin (CP) is the plasma protein that functions as a copper transporter. The current retrospective research was carried out to assess CP contents and to examine the possible part in diagnosing patients with AAD. In addition, propensity score matching (PSM) was also utilized for reducing the bias in case screening as well as the clinical confounders. Using PSM, this study included 85 pairs of AAD cases (Stanford A and B dissection) and matched controls, and their CP levels were also detected through enzyme-linked immunosorbent assay (ELISA). Additionally, the relative clinical data were extracted from participants included in this study. After PSM adjustment for clinical variables, including gender, age, body mass index (BMI), heart ratio (HR), smoking, hypertension, diabetes mellitus, coronary heart disease (CHD), and stroke, the serum CP contents among AAD cases were remarkably increased compared with those among the normal subjects. Besides, the CP contents showed independent association with the AAD risk. Typically, the CP level was significantly positively correlated with platelet (R = 0.329) or C-reactive protein (R = 0.340) level. Meanwhile, the area under the receiver operating characteristic (ROC) curve (AUC) was 0.929 when CP was used to diagnose AAD, and the best threshold value was 36.82mg/dL. Serum CP content significantly increased in cases with thrombosed false lumen (FL) relative to those in patent FL cases. Results of logistic regression analysis suggested that a greater CP content indicated an increased thrombosed FL risk (OR = 1.11; 95% CI: 1.01-1.23; P = 0.040). Findings in this study suggest that serum ceruloplasmin contents evidently increased among acute aortic dissection cases. CP shows close correlation with the inflammatory factors among AAD cases. Further, CP may serve as the candidate biomarker to diagnose AAD and to identify an increased risk of thrombosed false lumen.

Abstract
BACKGROUND Acute aortic dissection (AAD) is a life-threatening disorder in vascular surgery with a high early mortality. Serum amyloid A (SAA) is a kind of acute-phase protein with a rapid diagnostic value in other diseases. However, the researches on the performance of SAA for the diagnosis of AAD is still lacking. This retrospective study aimed to evaluate the SAA levels and further explore its potential diagnostic role in AAD patients. METHODS SAA levels were measured by enzyme-linked immunosorbent assay (ELISA) in 63 controls and 87 AAD patients. Laboratory examinations were also performed. And relative clinical information was collected from participants included in this study. RESULTS SAA levels were significantly higher in AAD patients than those in healthy controls. SAA levels were independently associated with the risk of AAD. There was a positive significant correlation between SAA and C reactive protein (R = 0.442, and P = 0.001). Based on receiver-operating characteristic (ROC) analysis, the area under the curve (AUC) of SAA for the diagnosis of AAD were 0.942 with optimal cut-off points of 0.427 mg/L. For in-hospital mortality, the AUC of SAA were 0.732 with optimal cut-off points of 0.500 mg/L. According to logistic regression analysis, higher SAA levels represent a higher risk of in-hospital mortality (OR = 1.25; 95%CI: 1.07-1.47; P = 0.005). CONCLUSION Our findings demonstrated that SAA levels were significantly enhanced in AAD. SAA was closely correlated with inflammatory parameters and coagulation-related parameters in AAD. Furthermore, SAA could be a potential bio-marker for identifying AAD in the early diagnosis. Finally, SAA > 5.0 mg/L are independently related to AAD in-hospital mortality.

Abstract
Uncomplicated type B aortic dissections have traditionally been managed non-operatively with aggressive blood pressure control. However, the best medical treatment is associated with a considerable risk of disease progression to complicated dissection or aneurysmal degeneration of the affected aortic segment. Thoracic endovascular aortic repair could prevent long-term complications but, because the dissected aorta is vulnerable, it is a high-risk procedure performed in asymptomatic patient. Therefore, endovascular treatment is not a solution for all patients and it should be performed only in the subgroup prone to developing progression of the disease and future complications. A number of studies have suggested several prognostic factors of early or late adverse events such as the patency of the false lumen in the follow-up, an initial aortic diameter ≥4 cm with a patent false lumen, an initial false lumen diameter ≥22 mm in the proximal descending aorta, visceral involvement and recurrent or refractory pain or hypertension. Partial false lumen thrombosis and a proximal entry tear size >10 mm have also been suggested to be associated with an increased rate of aortic growth. We need randomised trials focused on these prognostic factors to reach level 1, class A recommendation for the optimal timing of intervention. Meanwhile, we have to discuss with the patient the pro and cons of this prophylactic, low-invasive but high-risk treatment to personalise medical care and provide the optimal risk-to-benefit ratio.

Abstract
Stanford type B aortic dissection (TBAD) is a life-threatening disease. Current therapeutic guidelines recommend medical therapy with aggressive blood pressure lowering for patients with acute TBAD unless they have fatal complications. Although patients with uncomplicated TBAD have relatively low early mortality, aorta-related adverse events during the chronic phase worsen the long-term clinical outcome. Recent advances in thoracic endovascular aortic repair (TEVAR) can improve clinical outcomes in patients with both complicated and uncomplicated TBAD. According to present guidelines, complicated TBAD patients are recommended for TEVAR. However, the indication in uncomplicated TBAD remains controversial. Recent results of randomized trials, which compared the clinical outcome in patients treated with optimal medical therapy and those treated with TEVAR, suggest that preemptive TEVAR should be considered in uncomplicated TBAD with suitable aortic anatomy. However, these trials failed to show improvement in early mortality in patients treated with TEVAR compared with patients treated with optimal medical therapy, which suggest the importance of patient selection for TEVAR. Several clinical and imaging-related risk factors have been shown to be associated with early disease progression. Preemptive TEVAR might be beneficial and should be considered for high-risk patients with uncomplicated TBAD. However, an interdisciplinary consensus has not been established for the definition of patients at high-risk of TBAD, and it should be confirmed by experts including physicians, radiologists, interventionalists, and vascular surgeons. This review summarizes the current understanding of the therapeutic strategy in patients with TBAD based on evidence and expert consensus.

Abstract
Although several studies have shown the relation between temperature/atmospheric pressure and pulmonary embolism (PE), their results are inconsistent. Furthermore, diurnal temperature range (DTR) and diurnal pressure range (DPR) were not fully evaluated for their associations with hospital admissions for PE. Study subjects comprised cases of 1,148 PE treated at institutions belonging to the Tokyo Cardiovascular Care Unit Network from January 2005 to December 2012. Patient data were combined with a variety of daily local climate parameters obtained from the Japan Meteorological Agency. Every 1°C increase in the DTR at lag0 corresponded to an increased relative risk of hospital admission for PE (odds ratio [OR] 1.036, 95% confidence interval [CI] 1.003 to 1.070). In the cooler season (November to April), an increase of 1 hPa (barometric pressure) in the DPR at lag4 and lag5 was associated with an increased relative risk of hospital admission for PE (OR 1.042, 95% CI 1.007 to 1.077 and OR 0.952, 95% CI 0.914 to 0.992, respectively). An increase in the PE hospitalization rate was seen only in the cool season. Using a metropolitan database, we showed that DTR and DPR have different impacts on hospital admissions for PE. In conclusion, we found that an increase in the DTR increases the PE hospitalization rate, especially during the cooler season. The impact of DTR and DPR on PE incidence and related hospitalizations needs to be further evaluated.

Abstract
BACKGROUND The Pulmonary Embolism Severity Index (PESI) and simplified PESI (sPESI) have not been fully evaluated in Japan, so the present study aimed to evaluate these risk stratification models in the prediction of mortality of affected patients in Japan. METHODS AND RESULTS We retrospectively analysed 302 PE patients (63.9±17.2 years of age; 42.4% male) from January 2011 to December 2012 using data from the Tokyo CCU Network. The areas under the receiver-operating characteristic curves were 0.92 (95% confidence interval (CI): 0.88-0.97) for the PESI and 0.88 (95% CI: 0.77-0.98) for the sPESI. CONCLUSIONS Both scores can be used to predict PE mortality in Japan.
