Purpose: Connecting outflow cannula of LVAD to the aorta is an underexplored issue but may have considerable impact. In fact the hemodynamic modifications due to implantation in this region can cause thromboembolic events. It is therefore important to unde ...
BACKGROUND Termination of persistent atrial fibrillation (AF) is a valuable ablation endpoint but is difficult to anticipate. We evaluated whether temporal and spatial indices of AF regularization predict intraprocedural AF termination and outcome. ...
Adrenergic receptors are a key component of nanoscale multiprotein complexes that are responsible for controlling the beat rate in a mammalian heart. We demonstrate the ability of near-field scanning optical microscopy (NSOM) to visualize b2-adrenergic rec ...
Cerebral vasospasm is a typical complication occurring after Subarachnoid Hemorrhage, which may
lead to delayed cerebral ischemia and death. The standard method to detect vasospasm is
angiography, which is an invasive procedure. Monitoring of vasospasm i ...
The mechanical interactions between heart contraction and perfusion of the heart are difficult to study in humans because of the restrictions in inducing changes in hemodynamic and cardiac mechanics parameters during catheterization. We hypothesize that th ...
Atrial fibrillation is the most common sustained cardiac rhythm disturbance, increasing in prevalence with age. During the past 20 years, there has been a 66% increase in hospital admissions related to atrial fibrillation. Neither the natural history of at ...
A major challenge for therapeutic delivery of angiogenic agents such as vascular endothelial growth factor (VEGF) is to achieve sustained, low dose signaling leading to durable neovessel formation. To this end, we recently created a variant of VEGF(121), T ...
Clinical standard 12-lead ECG recordings over 5 minutes on patients in atrial fibrillation or in atrial flutter were analyzed. After suppression of the signal components related to ventricular activity, the amplitude spectra of all leads were inspected. Th ...
The Saint-Marc dam, owned by EDF-France is a concrete gravity dam built between 1926 and 1930. It is located near Limoges (France) on the Taurion River and has currently two gated spillways, one 7.50 m wide on the right bank and the other with two passes o ...
Muscular arteries possess the ability to control actively their lumen by altering the tone of the smooth muscle cells of the arterial wall, a property which is vital for a large number of the hemodynamical functions of the body. Arterial contraction is due ...
