The noninvasive reference standard for myocardial fibrosis detection on cardiovascular magnetic resonance imaging (CMR) is late gadolinium enhancement (LGE). Currently there is no consensus on the preferred method for LGE quantification. Moreover myocardial wall thickening (WT) and strain are measures of regional deformation and function. The aim of this research was to systematically compare in vivo CMR parameters, such as LGE, WT and strain, with histological fibrosis quantification. Eight weeks after 90 min ischemia/reperfusion of the LAD artery, 16 pigs underwent in vivo Cine and LGE CMR...

OBJECTIVE: Stiffening of the aorta often precedes coronary events, but little is known about the aetiological mechanism. We hypothesized that the predisposition to myocardial ischemia could be attributable to aortosclerosis-induced alterations in the central haemodynamics during diastole. METHODS: Using noninvasive tonometry and ultrasonography, we investigated the arterial pressure pulse waveforms, pulse wave velocities (PWVs) and compliance in 222 patients with hypertension...

INTRODUCTION: Trophic disorders of the extremities are a common complication of systemic sclerosis (SSc), mainly related to microvascular damage. However, SSc seems to be a risk factor for premature athero-thrombotic disease that can affect the peripheral arteries, participate in the occurrence of trophic disorders and promote the occurrence of infectious complications. The objective of this study was to assess the prevalence of arterial disease of the limbs in SSc patients. METHODS: Consecutive inclusions in the context of a multidisciplinary consultation centered on disability of the hand with collection of clinical data [cardiovascular risk factors (CVRF), history of trophic disorders of ischemic origin, peripheral pulse palpation, Allen maneuver the upper (UL) and lower limbs (LL)], and hemodynamic data (flow recorded by Doppler in radial, ulnar, anterior and posterior tibial arteries, and measurement of systolic indices ankles)...

Trans-ulnar access is a viable alternative approach by experienced operators when the radial and femoral arteries cannot be accessed or used to preserve the contralateral radial artery as possible vascular graft for coronary bypass surgery, hemodynamic monitoring, or shunt creation for hemodialysis. We report a challenging case of ipsilateral trans-ulnar recanalization of a chronic radial artery occlusion, which allowed us to perform a complex trans-ulnar PCI.

BACKGROUND: Takayasu arteritis is a granulomatous panarteritis that predominantly affects the aorta and its major branches. The initial manifestations of this large-vessel vasculitis are usually nonspecific; however, as the disease progresses, typical symptoms of arterial occlusion, aneurysmal formation, and vascular pain become evident. Ischemic ocular complications of Takayasu arteritis which could lead to complete loss of vision are not uncommon and depend on the obliterated portion(s) of carotid(s), the intensity and rate of progression of ocular vascular insufficiency, and sufficiency of the collateral blood supply to the eye...

OBJECTIVE: Minimally invasive coronary artery bypass grafting (MICS CABG) via a small left thoracotomy is a novel technique for coronary revascularization that is increasingly used around the world. However, multivessel MICS CABG is difficult, and concerns about repeat revascularization (RR) have been raised. This longitudinal study describes the rates of RR among patients who have undergone MICS CABG and identifies targets for improvement. METHODS: A prospective observational study was performed on the 306 MICS CABG patients operated on by a single surgeon from 2005 to 2015...
