Redo cardiac surgery in patients with severe aortic insufficiency can present unique challenges to the anesthesiologist. We report a case highlighting the challenge and importance of interdisciplinary planning between cardiothoracic surgeons and anesthesiologists prior to high-risk surgery. Failure to place an endoaortic balloon and percutaneous coronary sinus catheter due to anatomical abnormalities prompted the adoption of an alternate technique involving apical ventricular venting to assist sternal reentry...

BACKGROUND: Diffuse intracranial aneurysmal vasculopathy is a rare condition, previously described in patients with human immunodeficiency virus (HIV) infection. IgG4 related disease (IgG4-RD) is a recognized inflammatory disease of systemic organs, leading to fibrosis of connective tissues. It has also been linked to inflammatory dilating aortic aneurysms, coronary vascular disease, hypophysitis, orbital pseudotumor and pachymeningitis. It has not yet been described as a cause of diffuse intracranial dilating vasculopathy...

Functional tricuspid valve (TV) regurgitation secondary to left heart disease (e.g. mitral insufficiency and stenosis) is observed in 75% of the patients with TV regurgitation and is thus the most common etiology; therefore, the majority of patients who require TV surgery, undergo concomitant mitral and/or aortic valve surgery. Uncorrected moderate and severe TV regurgitation may persist or even worsen after mitral valve surgery, leading to progressive heart failure and death. Patients with moderate to severe TV regurgitation show a 3-year survival rate of 40%...

BACKGROUND: Calcific aortic stenosis (CAS) is the most common heart valve disorder. To explore the underlying mechanisms, we investigated whether key microRNAs in calcified aortic valves are differentially expressed compared to those in the non-calcified valves. METHODS: Calcified aortic valves from patients with aortic stenosis and non-calcified aortic valves (control) from patients with aortic insufficiency (n = 8 per group) were obtained during cardiac valve replacement surgery...

Tomonobu Abe, Akihiko Usui
Acute mesenteric ischemia as malperfusion syndrome associated with acute aortic dissection is a difficult situation. The incidence is approximately 3~4% in acute type A dissection. Traditionally, most of these patients underwent immediate simple central aortic repair expecting that mesenteric artery obstruction and intestinal ischemia would be resolved by simple central aortic repair. However, short term mortality has been reported very high in this strategy. With the aid of rapidly progressing imaging techniques and newer endovascular repair techniques, results seem to be improving in recent years...

Hiroki Kato, Yoshiro Matsui
Low cardiac syndrome( LOS) is the imbalance of the oxygen supply and demand at the tissue due to reduced oxygen supply by decreased cardiac function. The causes of the cardiac dysfunction are insufficient cardioplegia, elongation of aortic clamp or cardiopulmonary bypass (CPB) duration, incomplete revascularization, and so on. The preventions of LOS are myocardial protections intraoperatively. The most important myocardial protection is to accomplish more quickly, accurately and safety to operation. And today, cardioplegia is essential for surgery requiring CPB...

Circumferential dissection is a rare clinical condition of aortic dissection, which is also known as intimo-intimal intussusception. In patients with type A aortic dissection with intimo-intimal intussusception, disruption and prolapse of the intimal flap into the left ventricle may occur and cause severe aortic regurgitation or blockage of the coronary artery ostium. A 43-year-old man presented with sudden dyspnea. Echocardiography revealed severe aortic insufficiency. Acute coronary syndrome was also suspected, but coronary angiography showed normal coronary arteries...

REVIEW
Michael H Kwon, Thoralf M Sundt
The bicuspid aortic valve (BAV) phenotype is becoming increasingly recognized as a complex and heterogeneous clinical entity, with some but not all patients developing accelerated degrees of both aortic insufficiency (AI) and aortic stenosis (AS) in comparison to patients with tricuspid aortic valves (TAV). In addition, there remains a well-established association between the BAV phenotype and aortic enlargement independent of valve function as well as progression among some to ascending aortic aneurysm and the attendant concern over risk of aortic dissection...

INTRODUCTION: The presence of symptoms, systolic dysfunction and Left Ventricle (LV) dilation are considered unfavourable prognostic markers in Aortic Valve Insufficiency (AVI). The role of diastolic dysfunction, which is considered unfavourable outcome marker in cardiac pathologies, is not well established in AVI. AIM: To evaluate if the presence of diastolic dysfunction may be associated with unfavourable prognostic markers in AVI patients. MATERIALS AND METHODS: A cross-sectional prospective study was performed on 22 patients with moderate or severe AVI...

In recent years the use of valve sparing techniques has become more common in selected patients with aortic valve insufficiency. However, limited experimental research has been performed to document the biomechanical effect of these techniques. One experimental platform is to evaluate how the normal physiological aortic root forces are altered or re-established after the surgical intervention. Hence, the aim of this project was to develop new implantable force transducers for a biomechanical description of various aortic root repair techniques...

One of the widely accepted adjunctive agents in the variety of surgical modalities are sealants. Our study aim was to compare four commonly used modern sealants in a standardized experimental setting to assess their feasibility, and hemostatic efficacy in vascular anastomosis. Forty landrace pigs (weight: 24.7 ± 3.8 kg) were randomized into the control (n = 8) and four sealant groups; TachoSil® (n = 8), Tissucol Duo® (n = 8), Coseal® (n = 8), and FloSeal® (n = 8). After doing a portal vein end-to-end anastomosis as well as stitches of aortic incision, the sealants were applied on anastomotic site...

Infective endocarditis (IE) may be accompanied by the production of a broad spectrum of autoantibodies, including antineutrophil cytoplasmic antibodies (ANCA). ANCA detection creates difficulties in the differential diagnosis of IE, especially in relation to kidney injury, the determination of the mechanism of which is important for choosing a treatment policy and estimating a prognosis. The paper describes a clinical case of a 57-year-old man who was found to have higher proteinase-3 (PR-3) ANCA titers along with the symptoms of anemia, purpura, and kidney injury during his hospitalization; echocardiography revealed vegetation on the aortic valve...

BACKGROUND: Bicuspid aortic valve (BAV) aortopathy is well known in literature even if only few data exist regarding isolated supra-coronary aneurysm with normally functioning valve and root. Aim of this study is to clarify the long-term fate of bicuspid aortic root spared at the time of ascending aorta surgery. METHODS: We identified forty-seven patients (mean age, 57±11 y; range, 35-81 y, 31 males) who were treated by means of supracoronary aortic replacement in presence of normally functioning BAV and not significantly enlarged sinues of Valsalva...

BACKGROUND: The efficacy of cold in situ perfusion and static storage of the liver is one possible determinant of transplantation outcomes. The aim of this study was to determine whether there is evidence to substantiate a preference for a particular perfusion route (aortic or dual) or perfusion/preservation solution in donation after brain-death (DBD) liver transplantation. METHODS: The Embase, Medline and Cochrane databases were utilized (1980-2017). Random effects modeling was used to estimate effects on transplantation outcomes based upon (i) aortic or dual in situ perfusion, and (ii) the use of University of Wisconsin (UW), histidine-tryptophan-ketoglutarate (HTK), Celsior and/or Institut Georges Lopez-1 (IGL-1) for perfusion/preservation...

PURPOSE: Morphine is administered intravenously for pain management in the perioperative period. The effect of the inflammatory response to surgery on morphine distribution across the blood-brain barrier (BBB) in humans was investigated. We hypothesized that a graded surgically induced, systemic inflammatory response alters cerebrospinal fluid (CSF) levels of morphine, morphine-3-glucuronide (M3G), and morphine-6-glucuronide (M6G) through a temporary reduction in BBB drug efflux transporter function...

Vasoconstrictive properties of sympathomimetic drugs are the basis of their widespread use as decongestants and possible source of adverse responses. Insufficiently substantiated practice of combining decongestants in some marketed preparations, such are those containing phenylephrine and lerimazoline, may affect the overall contractile activity, and thus their therapeutic utility. This study aimed to examine the interaction between lerimazoline and phenylephrine in isolated rat aortic rings, and also to assess the substrate of the obtained lerimazoline-induced attenuation of phenylephrine contraction...
