OBJECTIVES The purposes of this study were to examine whether tethering of the mitral leaflets affects coaptation in patients with functional mitral regurgitation (FMR) and to assess the interaction between the mitral coaptation and mitral regurgitation severity. BACKGROUND Functional mitral regurgitation causes restriction of leaflet closure as a result of enhanced tethering of the mitral le...

BACKGROUND left ventricular (LV) remodeling can increase tethering force to mitral valve and functional mitral regurgitation (FMR). Because the relationship between FMR and regional myocardial function has not been quantitatively evaluated, we conducted a quantitative investigation of this association. METHODS AND RESULTS the effective regurgitant orifice (ERO) of FMR in 51 patients with depr...

OBJECT The aim of this study was to evaluate different types of sensory stimulation used to distinguish between microvasculature and venous drainage on functional magnetic resonance (fMR) images with blood oxygen level-dependent (BOLD) contrast. METHODS Seven volunteers received three sensory stimulations. One consisted of small discontinuous automated pokes to the ventral aspect of the right...

A Distrofia muscular laminin subunit alpha 2 (DM LAMA2) é caracterizada pela deficiência da proteína cadeia laminina α2, apresentando sintomas distróficos que progridem na infância. Objetivo: Apresentar dados avaliação fisioterapêutica de uma criança com DM LAMA2 em acompanhamento ambulatorial. Métodos: Pesquisou-se prontuário referentes às avaliações fisioterapêuticas 12 anos diagnóstico atend...

The broadband ferromagnetic resonance FMR linewidth of the free layer of magnetic tunnel junctions is used as a simple diagnostic of the quality of the magnetic structure. The FMR linewidth increases near the field regions of free layer reversal and pinned layer reversal, and this increase correlates with an increase in magnetic hysteresis in unpatterned films, low-frequency noise in patterned ...

b Blockers have been shown to reverse left ventricular remodelling (LVR) and to reduce the severity of functional mitral regurgitation (FMR) in patients with chronic systolic heart failure. It is unclear, however, to what extent the beneficial effects of b blockers on LVR or FMR are influenced by the severity of left ventricular dilatation or FMR at the time of commencement of b blocker treatme...

In the era of structural heart disease where catheterbased treatment is prevailing, surgery may have a unique role. For example, surgery may be potentially advantageous in functional mitral regurgitation (FMR), a ventricular disease that not only needs valvular treatment but also requires a ventricular intervention. Being stimulated by the innovative work by Kron et al. (1), we reported anterio...

BACKGROUND AND PURPOSE Functional connectivity MR (fcMR) imaging is used to map regions of brain with synchronous, regional, slow fluctuations in cerebral blood flow. We tested the hypothesis that focal cerebral lesions do not eradicate expected functional connectivity. METHODS Functional MR (fMR) and fcMR maps were acquired for 12 patients with focal cerebral tumors, cysts, arteriovenous mal...

The intrinsic magnetic relaxations in metallic films will be discussed. It will be shown that the intrinsic damping mechanism in metals is caused by incoherent scattering of itinerant electron-hole pair excitations by phonons and magnons. Berger @L. Berger, Phys. Rev. B 54, 9353 ~1996!# showed that the interaction between spin waves and itinerant electrons in multilayers can lead to interface G...

OBJECTIVES Surgical mitral repair is the conventional treatment for severe symptomatic functional mitral regurgitation (FMR). Mitraclip therapy is an emerging option for selected high-risk patients with FMR. The aim of this study was to report the outcomes of patients who underwent a surgical mitral repair and Mitraclip therapy for FMR in our experience. METHODS From March 2000 and April 2011...
