Hace 5 días · Lumbar spinal stenosis (LSS) is one of the main causes of chronic pain and disability, affecting approximately 103 million people worldwide. 1 The degenerative changes in the discs, ligamenta flava, and facet joints lead to the narrowing of the spaces around the neurovascular structure of the spine, resulting in substantial pain, impaired ambulation, and disability. 2 Typical symptoms of LSS ...
Hace 2 días · Introduction Rheumatic heart disease (RHD), degenerative aortic stenosis (AS), and congenital valve diseases are prevalent in sub-Saharan Africa. Many knowledge gaps remain in understanding disease mechanisms, stratifying phenotypes, and prognostication. Therefore, we aimed to characterise patients through clinical profiling, imaging, histology, and molecular biomarkers to improve our ...
Hace 21 horas · Transcatheter valve replacement outcomes similar to surgery for severe aortic stenosis. A new study demonstrates parity between a minimally invasive procedure to replace the aortic valve in the ...
2 de may. de 2024 · Pulmonary vascular stenosis caused by FM is mostly bilateral, and the PA and PV are involved simultaneously; the right inferior PV is rarely involved. We developed a scoring system to evaluate the overall degree of pulmonary vascular stenosis, which can also predict the PVR and sPAP.
Hace 21 horas · Right ventricular (RV) dysfunction in patients undergoing transcatheter aortic valve implantation (TAVI) for aortic stenosis (AS) has long been disregarded. We aimed to assess the predictive value of RV to pulmonary artery coupling (RV/PAc), defined as tricuspid annular plane systolic excursion to systolic pulmonary artery pressure, on mortality in different flow types of AS after TAVI.
Hace 1 día · These stents can also be safely removed from patients who require stent removal, similar to silicone stents. 1, 2 Few similar reports exist on combination therapy with molecular-targeted agents and an airway stents. 4-7 It has been reported that airway stenosis in an ALK-positive lung cancer case with severe airway stenosis improved after ALK-TKI treatment and temporary placement of a silicone ...
7 de may. de 2024 · BACKGROUND AND PURPOSE: In fetuses with lateral ventriculomegaly and normal posterior fossa cerebrospinal spaces, third ventricular distention is a compelling clue that supports a diagnosis of aqueductal stenosis. However, this association assumes normal ventricular anatomy. Structural constraints can impair pressure-induced compliance. We aimed to determine how thalamic massa intermedia (TMI ...
