Although chronic kidney disease (CKD) is strongly associated with onsets of cardiovascular disease (CVD), the pathogenic mechanism between these diseases has not been fully understood. To develop and validate new therapeutic strategies for this complication, appropriate experimental models that reflect the complexity of the underlying pathophysiology are needed. The Osborne-Mendel (OM) rat was identified as an atherosclerosis-prone and a premature-death rat strain among 16 inbred rat strains when fed high-cholesterol containing diet...

Middle cerebral artery (MCA) aneurysms usually arise at the primary MCA bifurcation or trifurcation. Distal MCA aneurysms are rarely considered as sources of aneurysmal subarachnoid hemorrhage (SAH). It has been reported that ruptured distal MCA aneurysms are associated with head trauma, neoplastic emboli, arterial dissection, or bacterial infection. We experienced five cases of ruptured distal MCA aneurysms and evaluated their clinical characteristics. Retrospective analysis of aneurysmal SAH at Kobayashi Neurosurgical Neurological Hospital was performed from January, 2004 to December, 2014...

A woman underwent ascending aortic aneurysm repair, aortic root and valve replacement, and coronary artery bypass grafting. Her postoperative course was complicated by stroke and status epilepticus. With supportive care and antiepileptics, her neurologic status improved. Intravenous heparin and aspirin were initiated. On postoperative day 13, she developed a large retroperitoneal hematoma with femoral neuropathy. Because her hematoma was not amenable to percutaneous drainage or surgical evacuation, and considering her comorbidities, a conservative approach was elected...

OBJECTIVE: While vein of Galen aneurysmal malformations (VGAM) can be diagnosed in the fetus, the challenge is predicting the occurrence of its two major complications: cardiopulmonary failure and encephalomalacia. This study attempts to determine which fetal brain MRI features might be used to predict the development of these complications at birth. METHODS: The cohort was extracted from a prospectively-assembled database of VGAM cases managed at a single referral centre from 2000 to 2014...

Sinus of Valsalva aneurysm accounts for only 1% of congenital cardiac anomalies. Sinus of Valsalva aneurysm can cause aortic insufficiency, coronary artery flow compromise, cardiac arrhythmia, or aneurysm rupture. Three-dimensional transesophageal echocardiography (3DTEE) represents an adjunctive tool to demonstrate the ruptured sinus of Valsalva with better delineation. We present an adult patient with rupture of noncoronary sinus of Valsalva aneurysm into the right atrium (RA). 3DTEE accurately delineated the site of rupture into the RA and showed the exact size and shape of the defect, which helped in the successful transcatheter closure of the defect with a duct occluder device...

Polyarteritis nodosa (PAN) is a systemic necrotising vasculitis preferentially targeting medium-sized arteries and not related with glomerulonephritis or small vessel involvement. Clinical manifestations of PAN are multisystem. The gastrointestinal, renal, cardiac, musculoskeletal, skin and central nervous systems may be involved. The aetiology remains unknown, and the ensuing vasculitis may lead to aneurysm formation and thrombosis in any organs of the body with resultant ischaemia. PAN of the intestines is a relatively common manifestation of this disease but rarely causes bowel ischaemia resulting in necrosis...

Sinus of Valsalva aneurysms are rare cardiac abnormalities that may be congenital or acquired. Patch closure or direct closure of the aneurysm orifice is a frequently performed surgical repair strategy. In this report, we present a rare case of an isolated giant right sinus of Valsalva aneurysm with aortic insufficiency and right coronary artery obstruction. We treated this patient by a valve-sparing aortic root remodelling procedure with partial preservation of the intact Valsalva sinuses and coronary artery bypass grafting with a favourable outcome...

Behçet disease (BD) is a multisystem disorder, with vasculitis as its underlying pathological process, in contrast to the classic triad of recurrent oral and genital ulcerations, with uveitis. Vascular involvement in BD includes venous thrombosis, arterial occlusion, and pulmonary artery and aortic aneurysm formation. Cardiac involvement is rare and often obscure. It includes intracardiac thrombi formation, and is associated with a poor prognosis. Our objectives are to describe two cases with BD, complicated with vascular and cardiac involvement, and to raise awareness of these rare complications, the needed routine surveillance, and thus to prevent inappropriate interventions, serious outcomes, and mortality...

INTRODUCTION: For those living with Kawasaki disease and coronary artery aneurysms, little is known about the psychosocial burden faced by parents and their children. METHODS: Exploratory, descriptive, mixed-methods design examining survey and interview data about health-related uncertainty, intrusiveness, and self-efficacy. RESULTS: Parents' uncertainty was associated with missed diagnosis, higher income, and maternal education. Higher uncertainty scores among children were associated with absence of chest pain and lower number of echocardiograms...

Immunoglobulin 4-related disease (IgG4-related disease) is a systemic inflammatory disease that presents with increases of serum IgG4. It may affect various systems, including the cardiovascular (CV) system. Assessment of serum IgG4 levels and involved organ biopsy are necessary for diagnosis. IgG4-related disease is characterized by fibrosclerosis, lymphocytic infiltration and presence of IgG4-positive plasma cells. The disease usually responds to treatment with corticosteroids and/or immunosuppressive medication...

BACKGROUND: Different types of cannulation techniques are available for minimally invasive cardiac surgery. At our institution, we favor a femoral platform for most minimally invasive cardiac procedures. Here, we review our results utilizing this cannulation approach. METHODS: We retrospectively reviewed all minimally invasive valve surgeries that were performed at our institution between January 2009 and January 2015. Operative times, lengths of stay, postoperative complications, and mortality were analyzed...

Computer simulations based on the finite element method (FEM) represent powerful tools for modeling blood flow through arteries. However, due to its computational complexity, this approach may be inappropriate when results are needed quickly. In order to reduce computational time, in this paper we proposed an alternative machine learning based approach for calculation of wall shear stress (WSS) distribution, which may play an important role in mechanisms related to initiation and development of atherosclerosis...

OBJECTIVE: Although endovascular repair of ruptured abdominal aortic aneurysms (rAAAs) is increasingly more prevalent and may yield better results, open repair of rAAAs is still commonly performed. Our goal was to assess the contemporary practice patterns and outcomes of open repair of rAAA. METHODS: The 2011-2014 American College of Surgeons National Surgical Quality Improvement Program targeted open AAA database was queried for all rAAAs. Patient characteristics, presentation, aneurysm details, and operative details were analyzed to identify factors that may affect outcome in this population of patients...

Behçet's disease (BD) is a multisystem inflammatory disorder. Intracardiac thrombus (ICT) formation is an uncommon but important complication of BD. Of the cases of Behçet's disease, we selected those with ICT. All patients fulfilled the diagnostic criteria of the International Study Group of Behçet's disease. The ICT in each case was confirmed by ultrasonography, computed tomography and MRI. Clinical features and laboratory parameters were determined. Among our 518 patients with BD, 8 were diagnosed as having intracardiac thrombus (ICT)...

INTRODUCTION: Dutch cardiovascular disease (CVD) prevention guidelines recommend the use of modified SCORE risk charts to estimate 10-year risk of fatal and nonfatal CVD (myocardial infarction, cerebrovascular disease and congestive heart failure). This combined risk is derived from the SCORE mortality risk using multipliers. These multipliers have been shown to underestimate overall CVD risk. We aimed to compare the current Dutch risk charts with charts that estimate a broader range of clinically relevant CVD using updated multipliers...

BACKGROUND: For coronary interventions the arterial access via the radial artery is associated with fewer vascular access site complications, and has been shown to reduce major bleeding when compared to the femoral approach. But the endomyocardial biopsy (EMB) approach is usually done by a transfemoral or cervical access known to be associated with an increased risk of artery puncture and its potential complications (i.e., false aneurysm, artery-venous fistula) and needs post-procedural immobilization...

BACKGROUND: Pulmonary artery aneurysm (PAA) occurs in some patients with pulmonary arterial hypertension (PAH). We evaluated the characteristics of cardiac dysfunction in patients with PAH complicated by PAA. METHODS: Echocardiography and right-heart catheterization were performed in 130 PAH patients to measure the maximum dimensions of the main pulmonary artery (MPA) trunk and evaluate right ventricular (RV) and left ventricular (LV) function. RESULTS: A diameter of >40mm was defined as PAA in the MPA trunk...
