BACKGROUND: The ascending aorta is an uncommon site for non-infective thrombus. In non-aneurysmal and non-atherosclerotic vessels this condition becomes extremely rare, while it represents a source of potential cerebral and peripheral embolic events. Currently, there is no consensus in the guidelines on how to treat a free floating thrombus in ascending aorta, therefore we present our decision making process and therapeutic strategy. CASE PRESENTATION: A healthy 48-year-old man was hospital admitted with acute abdominal pain...

OBJECTIVES: The treatment of patients with extensive thoracic aortic disease involving the arch and descending aorta is often performed using the frozen elephant trunk technique (FET). Spinal cord blood flow (SCBF) in cervical, thoracic and lumbar sections prior, during and after aortic arch surgery were compared in conventional elephant trunk (cET) and FET technique in a pig model. METHODS: German Landrace pigs (75-85 kg) underwent aortic arch surgery using the FET ( n  = 8) or cET ( n  = 8) techniques...

The aim of this study was to document the detailed anatomy of neural course and distribution on the anterior ascending aorta, to identify the high and low density areas of the anterior ascending aortic plexus for further understandings in cardiovascular surgery. The embalmed hearts of 42 elderly individuals were submacroscopically and microscopically examined, after excluding any that were macroscopically abnormal. With its origins in the anterior ascending aortic plexus, the right coronary plexus substantially innervated the right coronary artery, the right atrium and ventricle, and the sinus node...

INTRODUCTION: Aorto-esophageal (AEF) and aortobronchial fistula (ABF) after TEVAR are rare complications with catastrophic consequences without treatment. In this case report we presented a patient with AEF and ABF after TEVAR successfully treated with endograft explantation and replaced by Dacron graft followed by esophagectomy and left principal bronchus repairing. CASE REPORT: We report a patient with AEF and ABF after TEVAR who was evaluated due to dysphagia and chest pain followed by hematemesis and hemoptysis...

Coarctation of aorta is a rare congenital malformation and is usually accompanied by other cardiac or vascular lesions. In this case we describe a 51-year-old patient presented with coarctation of the aortic arch and postcoarctation ectasia concomitant with a left subclavian artery aneurysm. Endovascular therapy included the deployment of an inverted wedge-shaped covered stent inserted by a long "chimney" stent and another cylinder-covered stent, forming a "sandwich"-like configuration. The symptoms were alleviated after surgery, and no perioperative or stent-graft-related complications were observed at a 2-year follow-up...

The TA11PA-C10 implantable transmitter (Data Sciences International, DSI) is designed to measure blood pressure (BP) and activity in freely moving laboratory mice. The fluid filled catheter is placed in the free flowing blood of the systemic artery (inserted into the left carotid artery and extended into the aorta), and the transmitter body is placed in a benign location for long-term biocompatibility. The transmitter can be used to monitor BP in mice (as small as 17 g) under normal physiological and unrestricted conditions 24 h a day while remaining free from stress associated with human interaction...

Invasive aspergillosis rarely involves the thoracic aorta, and is associated with a poor prognosis. A heart-transplanted 56-year old patient presented with invasive aspergillosis, primary aspergillus aortitis, and ruptured thoracic aorta pseudoaneurysm. Open surgery was not possible due to severe sepsis. A sequential surgical strategy was therefore decided, including emergency thoracic endovascular aneurysm repair, followed by antifungal treatment, and definitive open repair with explantation of the endograft and placement of a cryopreserved arterial allograft under extra-corporeal membrane oxygenator support...

BACKGROUND: Body surface area (BSA)-indexed Z-scores are used to assess the ascending aorta (AAo) and diagnose aortic dilation (AoD) in children. BSA is directly related to body weight and corresponds to body mass index (BMI). We hypothesized extremes in BMI alter interpretation of aortic size in pediatric patients with AoD. METHODS: We reviewed all echocardiograms with a diagnosis of AoD performed at our institution from January 2013 through June 2013. Those with an age <2 or >20 years, history of aortic root surgery, or inadequate images were excluded...

A 72-year-old man presented with aneurysms of the distal aortic arch and the distal descending aorta due to chronic type B aortic dissection. We first performed thoracic endovascular aortic repair (TEVAR) in the distal descending aorta, and the aneurysm was successfully excluded using a Gore Tag stentgraft. Seven days after TEVAR, computed tomography revealed retrograde type A aortic dissection occurring from the ascending aorta to the distal aortic arch. In emergency surgery, ascending aorta and total arch replacement were performed under selective cerebral perfusion with moderate hypothermia, and after coming off cardiopulmonary bypass, the distal aortic arch aneurysm was excluded using a Gore Tag stentgraft...

Aortic valve stenosis alters blood flow in the ascending aorta. Using intra-operative vector flow imaging on the ascending aorta, secondary helical flow during peak systole and diastole, as well as flow complexity of primary flow during systole, were investigated in patients with normal, stenotic and replaced aortic valves. Peak systolic helical flow, diastolic helical flow and flow complexity during systole differed between the groups (p < 0.0001), and correlated to peak systolic velocity (R = 0.94, 0...

INTRODUCTION: The biggest challenge faced in minimally invasive pediatric cardiac surgery is cannulation for cardiopulmonary bypass. Our technique and experience of cervical cannulation in infants and small children for repair of congenital cardiac defects is reported in this study. METHODS: From January 2013 to June 2015, 37 children (22 males) with mean age of 17.97±8.63 months and weight of 8.06±1.59 kg were operated on for congenital cardiac defects through right lateral thoracotomy...

A 74-year-old hemodialysis patient with a history of an atrial septum defect closure, coronary bypass surgery, and a St. Jude aortic prosthetic valve was diagnosed with pneumonia and volume overload. Blood cultures were positive for Listeria monocytogenes, and amoxicillin was given for 2 weeks. Immediately after discontinuation of amoxicillin, fever relapsed. Transthoracic and transesophageal echocardiography showed no sign of endocarditis. Given the fever relapse and 3 positive minor Duke criteria, an (18)F-FDG PET-CT scan ((18)F-fluorodeoxyglucose-positron emission tomography-computed tomography) scan was performed...

Aortoenteric fistulae are life-threatening conditions characterized by abnormal communications between the aorta and gastrointestinal tract. Aortoenteric fistulae may be characterized by the triad of bleeding, abdominal pain, or a pulsatile abdominal mass. Although hemorrhage is the most common presentation, it does not always occur; thus, patients may present with nonspecific symptoms. Computed tomography angiography findings suggestive of aortoenteric fistulae include ectopic gas within or adjacent to the aorta, discontinuity of the aortic wall, bowel wall thickening, and extravasation of contrast into the bowel...

One of serious obstacles of the aortopathies research is a considerable shortage of human aortic smooth muscle cells (SMC), which can be used to model the disease. SMC in most cases come from the whole aorta of transplant donors, which are rather difficult to access. In the course of coronary artery bypass graft (CABG) surgery a fragment of aortic tissue is excised to make a bypass root. In this study we show a possibility to use CABG leftover fragments of thoracic aorta as a source of human SMC for in vitro research...

A case of an unusual iatrogenic aortic dissection is reported. A 77-year-old male patient in shock status due to acute type A aortic dissection underwent emergency surgery. Systemic perfusion was started via the femoral artery, but another dissection appeared in the descending aorta detected by transoesophageal echocardiography. However, the flap was unusually thin, and there was no change in the pre-existing thrombosed false lumen. These findings suggested subintimal development of dissection. After systemic perfusion was promptly switched to antegrade perfusion, the new dissection could no longer be detected...

PURPOSE: Despite a substantial amount of literature on tissue-guided regeneration, decellularization process, repopulation time points and stem cell turnover, more in-depth study on the argument is required. Currently, there are plenty of reports involving large animals, as well as clinical studies facing cardiac repair with decellularized homografts, but no exhaustive rodent models are described. The purpose of this study was to develop such a model in rats; preliminary results are also herein reported...

Clostridium septicum is a rare organism, accounting for approximately 1.3% of clostridial infections and is associated with synchronous colonic malignancy. This case report describes a patient successfully treated for a mycotic aortic aneurysm secondary to C. septicum bacteremia. Subsequent evaluation confirmed a colonic malignancy, prompting early intervention. A systematic literature review revealing a rate of gastrointestinal malignancy in this patient population is 71%, hematologic malignancy is 3.9%, with the remaining cohort of patients having an unknown source...

BACKGROUND: Risk factors for developing heart valve and ascending aortic disease are based mainly on retrospective data. To elucidate these factors in a prospective manner, we have performed a nested case-referent study using data from large, population-based surveys. METHODS AND RESULTS: A total of 777 patients operated for heart valve disease or disease of the ascending aorta had previously participated in population-based health surveys in Northern Sweden. Median time (interquartile range) from survey to surgery was 10...
