BACKGROUND: Diabetes mellitus has long been associated with cardiovascular events. Nevertheless, the higher burden of traditional cardiovascular risk factors reported in high-income countries is offset by a more widespread use of preventive measures and revascularization or other invasive procedures. The aim of this investigation is to describe trends in number of cases and outcomes, in-hospital mortality (IHM) and length of hospital stay (LHS), of hospital admissions for major cardiovascular events between type 2 diabetes (T2DM) and matched non-diabetes patients...

Acute aortic dissection (AAD) is a catastrophic emergency with high mortality and misdiagnosis rate. We aimed to determine whether circulating microRNAs allow to distinguish AAD from healthy controls and chest pain patients without AAD (CP). Plasma microRNAs expression were determined in 103 participants, including 37 AAD patients, 26 chronic aortic dissection patients, 17 healthy volunteers, 23 patients without AAD. We selected 16 microRNAs from microarray screening as candidates for further testing via qRT-PCR...

INTRODUCTION: Predicting aortic growth in acute type B dissection is fundamental in planning interventions. Several factors are considered to be growth predictors in the literature and, among them, size and location of entry tears have been recognized to particularly influence the false lumen pressure. In this study, we develop an in vitro setting to analyze the actual impact of size and location of the entry tears on false lumen pressure, in the absence of other confounding factors such as the deformability of the aortic wall...

OBJECTIVES: The recommended extent of surgical resection and reconstruction of the arch in acute DeBakey Type I aortic dissection is an ongoing controversy. However, several recent reports indicate a trend towards a more extensive arch operation in several institutions. We have analysed the recent data from the International Registry of Acute Aortic Dissection to assess the choice of procedure over time and to evaluate the surgical outcome in a 'real-world' database. Our aim was to compare short- and mid-term outcomes of limited repairs versus complete arch surgery...

OBJECTIVES: Distal anastomotic new entry (DANE) is considered to be one of the causes of patent false lumen (PFL) after acute type I aortic dissection repair. However, there have been few articles with regard to this important issue. We assessed the influence of PFL caused by DANE on long-term outcomes. METHODS: One hundred twenty-two patients underwent emergency surgery for acute type I aortic dissection (2007-12). The in-hospital mortality was 8% (10 patients)...

OBJECTIVES: Our goal was to report our preliminary results in patients with acute complicated Type B aortic dissection without a suitable landing zone for primary thoracic endovascular aortic repair who were treated with the frozen elephant trunk (FET) technique. METHODS: Within a 25-month period, 14 patients with acute complicated Type B aortic dissection underwent surgical repair using the FET technique. The reasons to perform the FET procedure were an ectatic ascending aorta/arch in 6 patients and the lack of an adequate landing zone in 8 patients...

BACKGROUND: Aortic dissection (AD) represents a clinically uncommon aortic pathology which predicts a dismal prognosis if not promptly treated. In acute Debakey type I AD (ADIAD), aortic lesion extends from aortic root to even distal abdominal aorta among which aortic arch and its three main branches still remain a great surgical challenge for repair and reconstruction. Several decades have witnessed the painstaking efforts of cardiovascular surgeons across the globe for optimizing the surgical procedures, from total or hemi-arch replacement, "elephant trunk" technique to branched stent graft...

BACKGROUND: Surgery for acute type A aortic dissection (ATAAD) is often complicated by excessive bleeding. Recombinant factor VIIa (rFVIIa) effectively treats refractory bleeding associated with ATAAD surgery; however, adverse effects of rFVIIa in these patients have not been fully assessed. Here we evaluated rFVIIa treatment in ATAAD surgery using the Nordic Consortium for Acute Type A Aortic Dissection (NORCAAD) database. METHODS: This was a multicenter, propensity score-matched, retrospective study...

Arterial cannulation in acute DeBakey type I dissection can be difficult. Moreover, the residual dissected aorta is susceptible to further adverse events in the future. Implanting a stent-graft into the descending aorta during the initial dissection repair ('frozen elephant trunk') has been demonstrated to promote favourable aortic remodelling, mitigating some of these longer-term complications. We describe a technique for cannulation of the ascending aorta in acute dissection that facilitates expeditious antegrade deployment of a frozen elephant trunk...

BACKGROUND: Although several hypotheses have been proposed, the true origin and pathogenesis of aortic intramural hematoma (IMH) remain unclear. Evolution of patients with aortic IMH is highly variable. Progression to classic aortic dissection, aneurysm or to complete resolution have been described. Our purpose was to assess in-hospital and mid-term evolution of patients with aortic IMH. METHODS: From 2000 to 2015, 40 patients with aortic IMH were prospectively and consecutively recruited in a tertiary care referral center...

The pathogenesis of acute aortic dissection (AAD) complicated acute lung injury (ALI) is not currently well defined. At present, no effective animal model has been established for AAD complicated ALI, which hinders research and development of an appropriate treatment regimen for the concurrent conditions. The aim of the present study was to evaluate the therapeutic effects of bindarit (Bnd), an indazolic derivative, on the production of monocyte chemoattractant protein (MCP)-1 in angiotensin II (AngII)-induced complicated ALI in rats...

Iatrogenic acute aortic dissection during percutaneous coronary intervention is an extremely rare but critical complication. Although sealing the entry point with a coronary stent is an option to treat localized dissections, more extensive cases may require surgical intervention. We present a case of Type A aortic dissection that occurred during an angioplasty of a chronically occluded right coronary artery. Despite the extent of the dissection, a 'watch-and-wait' strategy was chosen, and repeated imaging a few days later revealed that the aorta had been remodelled to its normal anatomy...

OBJECTIVES: Thoracic endovascular aortic repair is the treatment of choice in complicated acute type B aortic dissection. How to infer predissection aortic diameter is not well understood. Our aim was to delineate changes in descending aortic geometry due to dissection. METHODS: Five tertiary centres reviewed their acute aortic dissection type B databases containing 802 patients. All patients who had undergone computed tomography angiography less than 2 years before and immediately after aortic dissection onset were included...
