Recently, sternal reentry has been performed with low perioperative mortality and morbidity. In some patients, however, there are specific problems leading to life-threatening events during sternal reentry. A 27-year-old woman with repaired Tetralogy of Fallot and the absent inferior caval vein was referred to our department for pulmonary conduit replacement. ...

We describe the natural history of an adolescent patient who developed an aortopulmonary fistula (APF) after transcatheter stent placement for left pulmonary artery stenosis after neonatal repair of d-transposition of the great arteries. Due to its rarity, the APF was not initially diagnosed and treated until 4 months later. The APF ...

BACKGROUND: Carotid artery stenting (CAS) is an alternative to carotid endarterectomy (CEA) for revascularization of the internal carotid artery (ICA). CAS from the femoral approach may be problematic due to peripheral vascular disease, anatomical variations of the aortic arch, and access site complications. The purpose of the present study was ...

Purpose: The standard approach in patients with a clotted arteriovenous fistula (AVF) on the forearm is the creation of another vascular access on the arm using the patient's own vessels or a prosthetic graft. Here we propose another option as secondary angioaccess for chronic hemodialysis (HD): superficialization of the radial ...

BACKGROUND: Osteopontin (OPN) and osteoprotegerin (OPG) have recently emerged as key factors in both vascular remodeling and development of atherosclerosis. Arterial stiffness has an independent predictive value for cardiovascular events. We evaluate the relationship between OPG, OPN serum levels and vascular function in coronary artery disease (CAD) patients. METHODS: The ...

OBJECTIVE: Matrix metalloproteinase-9 is considered to play a pivotal role in aneurismal formation. We showed that gingival fibroblasts (GF) in vitro reduced matrix metalloproteinase-9 activity via increased secretion of tissue inhibitor of metalloproteinase 1. We aimed to evaluate in vivo the efficacy of GF transplantation to reduce aneurism development in ...

Tracheobronchial compression of cardiovascular origin is an uncommon and frequently unrecognised cause of respiratory distress in children. The compression may be due to encircling vessels or dilated neighbouring cardiovascular structures. Bronchoscopy and detailed radiography, especially computed tomography and magnetic resonance imaging, are among the most powerful diagnostic tools. Few previous ...

Studies investigating cognitive impairment in stroke-free patients with carotid artery stenosis have led to inconsistent results. Furthermore, the pathophysiological mechanism leading to cognitive impairment remains unclear. Cerebral hypoperfusion and arterio-arterial microembolization are discussed. The aims of our study were (1) to delineate patterns of cognitive impairment in stroke-free patients with ...

A 73-year-old woman with type III coronary perforation caused by failed angioplasty underwent emergency operation. It was impossible to stop the bleeding from the beating heart because the proximal Cx, which was the perforation site, was behind the main pulmonary artery. After establishing cardiopulmonary bypass, we separated the main pulmonary ...

BACKGROUND: Fiber intake is associated with lower cardiovascular disease risk. Whether arterial stiffness is influenced by lifetime fiber intake is not known. Any such association could explain, at least in part, the cardioprotective effects attributed to fiber intake. OBJECTIVE: The objective was to investigate whether a lower intake of fiber ...

OBJECTIVES: Left main disease (LMD), combined with carotid artery stenosis (CAS), constitutes a high-risk patient population. Priority is often given to coronary revascularization, due to the severity of the angina. However, the choice of revascularization strategy [off-pump coronary artery bypass (OPCAB) vs. coronary artery bypass grafting (CABG)] remains elusive. METHODS: ...

The assessment of both geometry and hemodynamics of the intracranial arteries has important diagnostic value in internal carotid occlusion, sickle cell disease, and aneurysm development. Provided that signal to noise ratio (SNR) and resolution are high, these factors can be measured with time-resolved three-dimensional phase contrast MRI. However, within a ...

In general, intravascular thrombus formation in the pulmonary arteries is considered to be the most common cause of chronic thromboembolic pulmonary hypertension (CTEPH). The current mainstay of therapy for patients with CTEPH is pulmonary endarterectomy (PEA). Recently, the existence of myofibroblast-like cells in endarterectomized tissues has been demonstrated. At the ...

The sound generated by blood flow in stenosed arteries is investigated for a model that consists of a channel with a one-sided constriction. The blood flow-induced arterial "bruits" are computed directly using a hybrid approach wherein the hemodynamic flow field is solved by an immersed boundary, incompressible flow solver, and ...

A 74-year old male presented with a dilatation of the thoracic aorta late after an acute aortic dissection. Computed tomography (CT) showed chronic dissecting aortic aneurysms just below the distal aortic arch. The total descending thoracic aorta was surgically replaced. Four weeks later, a massive bloody effusion developed in the ...

The retropharyngeal internal carotid artery (ICA) is a well-described arterial anomaly with important implications for patients undergoing pharyngeal approach surgical procedures. Existing clinical and imaging classification schemes for a retropharyngeal ICA take into account arterial distance to the pharyngeal mucosal wall. We describe a case of mobility of a retropharyngeal ...
