Introduction. The viability and immunological response induced by cryopreserved arterial allografts remain unclear. This study examines the post-graft behaviour of this type of vessel substitute. Materials and methods. Both iliac arteries were extracted from Lewis rats (donors) and used to establish groups of allogeneic fresh (group I) or cryopreserved (group ...

A 63-year-old man underwent aortic valve replacement and an early reoperation for recurrent endocarditis. Sixteen months later he presented with persistent fever and a 64-slice computed tomography (CT) scan revealed a subannular left ventricular pseudoaneurysm. He underwent successful left ventricular outflow tract reconstruction and aortic valve prosthesis, partial root and ...

Stent migration from the delivery balloon catheter is a rare but serious complication during percutaneous coronary intervention, particularly when a part of the stent stretches into the aorta. We report an unusual case of stent migration treated with a combination of a gooseneck snare and rotablation. A part of the ...

There have been several reports of gas embolism occurring during off-pump coronary artery bypass graft (OPCAB) surgery. However, all these cases of air embolism were associated with the repair of venous circulation, using a CO(2) blower. In this report, we describe a rare case of air embolism in the coronary ...

Syncope, defined as a transient loss of consciousness, is seen in 1% of all visits to emergency departments and urgent care clinics in the United States. Syncope is categorized as cardiogenic, neurologic, or psychogenic. Anomalies of the coronary arteries are rare, and anomalous coronary arteries present as syncope more often ...

To track variations in the deformation of the arterial wall noninvasively by estimating the accumulated displacement and strain over a cardiac cycle may provide useful indicators of vascular health. In this paper, we propose an approach to track a region of interest (ROI) locally and estimate arterial stiffness variation in ...

Although rare, iatrogenic aortocoronary dissection is one of the complications most dreaded by the interventional cardiologist. If not managed promptly, it can have redoubted and serious consequences. Herein, we present the case of a 70 year-old woman who was treated by stenting of the second segment of the right coronary ...

It is not known whether the mild hypoxia experienced by passengers during commercial air travel triggers hypoxic pulmonary vasoconstriction and increases pulmonary artery pressure in flight. Insidious pulmonary hypertensive responses could endanger susceptible passengers who have cardiopulmonary disease or increased hypoxic pulmonary vascular sensitivity. Understanding these effects may improve pre-flight ...

Excessive stretching of the vascular wall in accordance with pulmonary arterial hypertension (PAH) induces a variety of pathogenic cellular events in the pulmonary arteries. We previously reported that indoxam, a selective inhibitor for secretory phospholipase A<SUB>2</SUB> (sPLA<SUB>2</SUB>), blocked the stretch-induced contraction of rabbit pulmonary arteries by inhibition of untransformed prostaglandin ...

Transcatheter aortic valve implantation (TAVI) is a possible, although off-label, alternative to conventional aortic valve replacement for high-surgical-risk patients with severe, non-calcified aortic regurgitation (AR). To date, feasibility has only been demonstrated with the Medtronic CoreValve prosthesis (MCV). This prosthesis needs the aortic sinuses to have enough width to avoid ...

Among posterior circulation arteries, the intracranial vertebral artery (ICVA) has been given the least attention, especially concerning treatment of occlusive lesions. Early clinicopathological studies showed that the ICVA was often occluded in patients with lateral medullary and posterior inferior cerebellar infarcts. Severe stenosis or occlusion of the ICVA was the ...

Transcatheter valve-in-valve implantation is an emerging treatment option for high-risk patients with failing aortic bioprostheses. The presence of the prosthesis stents is thought to prevent coronary artery obstruction, a known complication of transcatheter aortic valve implantation in the native aortic valve. The Sorin Mitroflow aortic bioprosthesis (Sorin Group, Saluggia, Italy) ...

Aortic pulse pressure (APP) is related to arterial stiffness and associated with the presence and extent of coronary artery disease (CAD). Besides, the left coronary artery (LCA) has a predominantly diastolic flow while the right coronary artery (RCA) receives systolic and diastolic flow. Thus, we hypothesized that increased systolic-diastolic pressure ...

During one-lung ventilation, ventilation-perfusion mismatch decreases the arterial concentration of inhaled anaesthetics due to the arterial-to-venous concentration difference. This study tested the hypothesis that in humans, the 'presumed effect-site concentration' (taken as the mid-point between the arterial and superior jugular venous concentrations) of inhaled anaesthetic falls during one-lung (vs two-lung) ...

Arterial cannulation is a common anaesthetic procedure that can be challenging and time-consuming in small children. By visualizing the position of the radial artery, near-infrared vascular imaging systems (NIRVISs) might be of assistance in arterial cannulation. The present study evaluates the effectiveness of an NIRVIS in arterial cannulation in infants. ...

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by the triad of epistaxis, telangiectasia and vascular malformations. Pulmonary vascular complications associated with this disease include pulmonary arteriovenous malformations (AVM) and, less frequently, pulmonary hypertension (PH). We report the case of a patient who presented multiple pulmonary AVM and ...
