001) and early diastolic untwisting rate (p = 0.002) as compared to patients with normal geometry. In the whole AFD population, neither radial strain nor circumferential strain correlated with LV mass, while global longitudinal strain and early diastolic untwisting rate did (both p  less then  0.001). Late gadolinium enhancement was significantly associated with longitudinal strain, twisting rate and early diastolic untwisting rate, with twisting rate being the most powerful independent predictor (β = - 0.461; p = 0.002). Findings demonstrate impairment of LV radial strain in AFD patients with preserved EF, even in a pre-hypertrophic stage. Development of LV hypertrophy and fibrosis make worse mostly longitudinal dysfunction.A fluoroscopic view perpendicular to the aortic valve annulus is required during transcatheter aortic valve implantation (TAVI) for obtaining an optimal deployment of the bioprosthesis. By predicting c-arm angulation, pre-procedural MDCT could decrease the number of aortograms, shorten the time of the procedure and reduce the amount of intra-arterial contrast agent. The aim of our study was to assess the accuracy of MDCT in predicting c-arm angulation at the cath. lab. In this single center study, we investigated MDCT prediction of c-arm angulation in patients having undergone a TAVI procedure using SAPIEN 3® (Edwards Lifesciences, USA). Prior to the procedure, an experienced radiologist had reported the angulation using dedicated software (CTreport). After the procedure, a blinded experienced radiologist retrospectively measured the angles using the same method (CTstudy). Interobserver variability was drawn from the comparison between CTreport and CTstudy. Then, the mean angular difference between the predicted MDCT angles (CTstudy) was compared to the working view recorded at the cath. lab. Seventy-nine patients (M/F = 0.65; mean age 85.2&nbsp;years ± 5.3) were included. Interobserver variability was 5.9 ± 6.1°. The mean absolute difference between MDCT and fluoroscopy was 8.8 ± 7.1°. The present study showed that MDCT could predict the coplanar fluoroscopic angles prior to TAVI using a balloon-expandable bioprosthesis Sapien 3® placed via a transfemoral approach with a mean angular difference of 8.8 ± 7.1°. Reproducibility was considered good as the mean difference between two independent measures was 5.9 ± 6.1°.Transthoracic echocardiography (TTE) and cardiac magnetic resonance (CMR) are current standard for assessing aortic regurgitation (AR). Regurgitant fraction (RF) can also be estimated by Doppler examination of the left subclavian artery (LSA-Doppler). However, a comparison of AR grading scales using these methods and a TTE multiparametric approach as reference is lacking. We evaluated the severity of AR in 73 patients (58 ± 15&nbsp;years; 57 men), with a wide spectrum of AR of the native valve. Using a recommended TTE multiparametric approach the AR was divided in none/trace (n = 12), mild (n = 23), moderate (n = 12), and severe (n = 26). [https://www.selleckchem.com/products/trastuzumab-emtansine-t-dm1-.html find more] RF was evaluated by LSA-Doppler (ratio between diastolic and systolic velocity-time integrals) and by CMR phase-contrast imaging (performed in the aorta 1&nbsp;cm above the aortic valve); the grading scales were then calculated. There were a good correlation between all methods, but mean RF values were greater with TTE compared with LSA-Doppler and CMR (39 ± 16% vs. 35 ± 18% vs. 32 ± 20%, respectively; p  45%. RF values for AR grading using TTE, LSA-Doppler and CMR correlate well but differ in groups with mild and moderate AR when using a recognized multiparametric echocardiographic approach. Clinical prospective studies should validate these proposed modality adjusted grading scales.Retrosigmoid craniotomy for microvascular decompression (MVD) has been traditionally performed via craniectomy. Various closure techniques have been described, yet factors associated with wound-related complications remain undetermined. Accordingly, herein, we sought to identify risk factors associated with wound-related complications after such procedures. An institutional retrospective case-control study was performed; outcomes of interest were cerebrospinal fluid (CSF) leak, wound dehiscence, wound infection, and pseudomeningocele. Univariate analysis was performed using Wilcoxon rank sum test for non-parametric continuous outcomes and chi-square test for categorical outcomes. Multivariate logistic regression was performed on binomial outcome variables. The study population included 197 patients who underwent MVD for trigeminal neuralgia (83.2%), hemifacial spasm (12.2%), vestibular nerve section (3.0%), and glossopharyngeal neuralgia (1.5%). The overall wound-related complication rate was 14.2% (n&nbsp;= 28), including twelve patients (6.1%) with CSF leak, ten patients (5.1%) with wound infection, ten patients (5.1%) with pseudomeningocele, and nine (4.6%) patients with wound dehiscence. Using multivariate logistic regression, preoperative anemia and current tobacco use were associated with significantly higher rates of complications (OR 6.01 and 4.58, respectively; p&nbsp; less then  0.05), including CSF leak (OR 12.83 and 12.40, respectively, p&nbsp; less then  0.05). Of note, use of synthetic bone substitute for cranioplasty was associated with a significantly lower rate of complications (OR 0.13, p&nbsp; less then  0.01). Preoperative anemia and current tobacco use significantly increased, while synthetic bone substitute cranioplasty significantly decreased, odds of wound-related complications, the need for treatment, and CSF leaks. Additionally, higher BMI, longer operative duration, and prior radiosurgery may increase risk for wound-related complications.A novel parvovirus was identified as a cell culture contaminant by metagenomic analysis. Droplet digital PCR (ddPCR) was used to determine viral loads in the cell culture supernatant and further analysis, by ddPCR and DNA sequencing, demonstrated that fetal bovine serum (FBS) used during cell culture was the source of the parvovirus contamination. The FBS contained ~ 50,000 copies of the novel parvovirus DNA per ml of serum. The viral DNA was resistant to DNAse digestion. Near-full length sequence of the novel parvovirus was determined. Phylogenetic analysis demonstrated that virus belongs to the Copiparvovirus genus, being most closely related to bovine parvovirus 2 (BPV2) with 41% identity with the non-structural protein NS1 and 47% identity with the virus capsid protein of BPV2. A screen of individual and pooled bovine sera identified a closely related variant of the novel virus in a second serum pool. For classification purposes, the novel virus has been designated bovine copiparvovirus species 3 isolate JB9 (bocopivirus 3-JB9).
