The Neochord Procedure After Failed Surgical Mitral Valve Repair

Surgical mitral valve reintervention is associated with significant morbidity and mortality, and repeat repair is not always feasible. We examine the clinical outcomes of the NeoChord procedure after failed conventional mitral valve repair. A total of 312 patients were treated with the NeoChord repair procedure between January 2014 and December 2018 at 5 European centers. Clinical and echocardiographic data were reviewed to identify patients who had a prior surgical mitral valve repair procedure. The primary endpoint (Patient Success) was a composite of placement of at least 2 neochordae and end-procedure mitral valve regurgitation (MR) ≤ mild, freedom from death, stroke, structural or functional procedure failure (MR > moderate), procedure or device-related unplanned procedures, cardiac-related rehospitalization, or worsening NYHA functional class at 1 and 2-year FU. Fifteen (15) patients were identified who required reoperation for failed surgical mitral valve repair. Mean time-to-reoperation was 2.7 years (2.2-6.1). Median intensive care unit stay was 24 hours and median hospitalization time was 7 days (6-8). No in-hospital deaths were observed. At discharge, mitral regurgitation was ≤ mild in 13 patients (86.7%). Patient success and freedom from more than mild MR were 92.3 ± 7.4% and 83.9 ± 10.4% at 1 and 2-year follow-up respectively. One high-risk patient presented with severe recurrent MR and died during surgical reintervention due to an acute aortic dissection. Selected patients can be successfully treated with the NeoChord procedure after failed surgical mitral valve repair. These results support a wider adoption of the NeoChord procedure as a first-line minimally invasive, alternative therapy to treat failed mitral valve repair

Long-term follow-up of Bentall procedure using the Perimount bioprosthesis and the Valsalva graft

Bentall procedure is the gold standard for aortic root pathologies when valve repair is not feasible. The development of durable bioprosthetic valves and improved vascular conduits allowed the implementation of bioprosthetic composite grafts; hereby, we performed a retrospective analysis of long-term follow-up of Bentall procedure using the Valsalva graft and the Perimount Magna Ease prosthesis

Nabiximols plus robotic assisted gait training in improving motor performances in people with Multiple Sclerosis

Background: Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system, affecting ambulation even in people with only mild neurological signs. Patients with MS frequently experience spasticity, which contributes significantly to impair their motor functions, including ambulation, owing to muscle stiffness, spasms, and pain. Objectives: To clarify the role of delta-9-tetrahydrocannabinol(THC):cannabidiol(CBD) oromucosal spray, coupled to robot-aided gait training (RAGT) using the Lokomat©Pro to improve functional ambulation in patients with MS. Methods: We compared 20 patients with MS, who were treated with THC:CBD oromucosal spray in add-on to the ongoing oral antispastic therapy (OAT) (group A), with 20 individuals with MS (matched for clinical-demographic characteristics) who were treated only with OAT (group B). Both the groups underwent RAGT using the Lokomat-Pro (three 45-minute sessions per week). Our primary outcome measures were the Functional Independence Measure (FIM) and the 10 meters walking test (10MWT). As secondary outcome measures we evaluated the brain cortical excitability by using Transcranial Magnetic Stimulation. Both parameters were taken before and after the end of the RAGT. Results: FIM improved in group A more than in group B (p<0.001). Moreover, 10MWT decreased in group A more than in group B (p<0.001). These clinical findings were paralleled by a more evident reshape of intracortical excitability in both upper and lower limbs, as suggested by motor evoked potential amplitude increase (p<0.001), intracortical inhibition strengthening (p<0.001), and intracortical facilitation decrease (p=0.01) in group A as compared to group B. Conclusions: Our results suggest that the combined THC:CBD-RAGT approach could be useful in improving gait performance in patients with MS

Do patients with multiple sclerosis benefit from semi-immersive virtual reality? A randomized clinical trial on cognitive and motor outcomes

: Multiple sclerosis (MS) is a demyelinating disease of autoimmune originate. A large proportion of patient present with cognitive deficits that negatively affect their quality of life, thus, a proper cognitive rehabilitation is mandatory. The aim of this study is to evaluate the effect of semi-immersive virtual reality training (sVRT) on neuropsychological and motor recovery individuals suffering from MS. We enrolled 60 MS patients, randomized into either the control group (CG: 30) undergoing a conventional cognitive training, or the experimental group (EG: 30), which performed sVRT. Cognitive and motor outcomes were investigated through clinical and neuropsychological scales before (T0) and at the end (T1) of each different training. Only in the EG, we observed a significant improvement in cognitive parameters and motor scores. Our data demonstrate that VR cognitive training could potentiate MS patients' rehabilitation outcome, with positive results on both motor and cognitive performance

External Stents for Vein Grafts in Coronary Artery Bypass Grafting: Targeting Intimal Hyperplasia

Progressive saphenous vein graft (SVG) failure remains a key limitation to the long-term success of coronary artery bypass grafting (CABG). SVG disease after the first year is dominated by intimal hyperplasia, which predisposes the SVG to thrombosis and accelerated atherosclerosis. The objective of this study was to review and summarize the latest experimental and clinical data on the use of mechanical external stents for vein grafts

Enuresis, incontinence, urodynamic findings and glycosaminoglycan urinary excretion

Objective - To determine quantitative variations of glycosaminoglycan urinary excretion and urodynamic findings in children affected with nocturnal enuresis and/or diurnal incontinence. Patients and methods - Glycosaminoglycan urinary excretion and cystomanometry has been measured in children with nocturnal enuresis and/or diurnal incontinence, aged 5-15 years, and in 27 age-matched healthy controls through carbazole-tetraborate method. Results - Children with nocturnal enuresis and diurnal incontinence have showed higher values of glycosaminoglycan urinary excretion as opposed to healthy children. Moreover a statistically significant difference has been observed between quantities excreted in enuretic and incontinent children as opposed to only enuretic ones. In patients with nocturnal enuresis and diurnal incontinence there was an alteration of urodynamic findings. Conclusions - On the basis of our preliminar results it is evidenced that urinary glycosaminoglycans and cistimanometry may constitute a useful marker for evaluating bladder wall physiopathology and for monitoring a potential damage at a mucosal level in a large number of subjects
