Paravalvular regurgitation after transcatheter aortic valve replacement with the Edwards sapien valve in the PARTNER trial: characterizing patients and impact on outcomes

Aim The impact of paravalvular regurgitation (PVR) following transcatheter aortic valve replacement (TAVR) remains uncertain. In this analysis, we sought to evaluate the impact of varying degrees of PVR on both mortality and changes in ventricular geometry and function. Methods and results Clinical and echocardiographic outcomes of patients who underwent TAVR from the randomized cohorts and continued access registries in the PARTNER trial were analysed after stratifying by severity of post-implant PVR, which was graded as none/trace in 52.9% (n = 1288), mild in 38.0% (n = 925), and moderate/severe in 9.1% (n = 221). There were significant differences in baseline clinical and echocardiographic characteristics. After TAVR, all the patients demonstrated increase in left ventricular (LV) function and reduction in the LV mass index, although the magnitude of mass regression was lower in the moderate/severe PVR group. The 30-day mortality (3.1 vs. 3.4 vs. 4.5%, P = 0.56) and stroke (3.4 vs. 3.7 vs. 2.3%, P = 0.59) were similar in all groups (none/trace, mild, and moderate/severe). At 1 year, there was increased all-cause mortality (15.9 vs. 22.2 vs. 35.1%, P

This study shows that CA are released from periventricular and subpial regions to the cerebrospinal fluid and are present in the cervical lymph nodes, into which cerebrospinal fluid drains through the meningeal lymphatic system. We also show that CA can be phagocytosed by macrophages. We conclude that CA can act as containers that remove waste products from the brain and may be involved in a mechanism that cleans the brain. Moreover, we postulate that CA may contribute in some autoimmune brain diseases, exporting brain substances that interact with the immune system, and hypothesize that CA may contain brain markers that m...

Abstract Background: Mitral valve repair in paediatric patients with chronic rheumatic heart disease is superior to valve replacement and has been used with good results. Objective: To identify predictors of unfavourable outcomes in children and adolescents submitted to surgical mitral valvuloplasty secondary to rheumatic heart disease. Methods: Retrospective study of 54 patients under the age of 16 operated at a tertiary paediatric hospital between March 2011 and January 2017. The predictors of risk for unfavourable outcomes were: age, ejection fraction, degree of mitral insufficiency, degree of pulmonary hypertension, pr...

CLEVELAND – Two words dominated much of the program agenda for Cleveland Clinic’s 2019 Medical Innovation Summit (MIS) on Tuesday – Artificial Intelligence. From a keynote address from Craig Mundie, Senior Advisor to the CEO, and former Chief Research and Strategy Officer, Microsoft to a session discussing companies with non-traditional approaches to healthcare, the topic of AI was discussed. But is AI just the latest fad in healthcare? Is it fully-defined? And are there real-world examples to look to, to see AI in action? Richard Zane, MD CIO of University of Colorado ...

AbstractBackgroundUntreated symptomatic high-grade aortic stenosis remains a lethal disease requiring individually adapted valve replacement. High-risk surgical patients benefit from transcatheter aortic valve replacement (TAVR), but there is no uniform standard for patient selection and valve sizing and it is still unclear whether transthoracic (TTE) or transesophageal (TEE) echocardiography is superior in preprocedural aortic annulus sizing. As preprocedural sizing of the native aortic annulus diameter is crucial to outcome and survival, we report the results of a direct comparison between preprocedural sizing with TTE a...

A new blood filtration technology may prove to be life-saving for patients whose normally healthy inflammatory response to injury or illness has gone into overdrive, resulting in fatally high levels of cytokines in their blood. In an interview with MD+DI, Dr. Phillip Chan, MD, PhD, CEO of CytoSorbents Corp., explained that inflammation, and the production of substances called cytokines that drive inflammation, are the body’s natural response to heal injury or infection. But sometimes, the inflammatory response is so severe in such conditions as sepsis and infection, burn injuries, trauma, pancreatitis, li...

CONCLUSION: Acute malfunctioning MHV during pregnancy represents a real dilemma to patients and caregivers. It carries high fetal and maternal morbidity and mortality, especially in centers with limited resources. We believe that an alternative plane must be formulated for such patients to avoid devastating complications, including maternal and fetal deaths. PMID: 31596721 [PubMed - in process]

In this study we show, for the first time, significant alterations in cholesterol efflux capacity in adolescents throughout the range of BMI, a relationship between six circulating adipocyte-derived EVs microRNAs targeting ABCA1 and cholesterol efflux capacity, and in vitro alterations of cholesterol efflux in macrophages exposed to visceral adipose tissue adipocyte-derived EVs acquired from human subjects. These results suggest that adipocyte-derived EVs, and their microRNA content, may play a critical role in the early pathological development of ASCVD.
