A novel echocardiography-based definition of atrial functional tricuspid regurgitation (A-FTR) has shown superior outcomes in patients undergoing conservative treatment or valve transcatheter edge-to-edge repair. Its prognostic significance for annuloplasty (TTVA) is unknown. This study sought to investigate prognostic, clinical, and technical implications A-FTR phenotype TTVA. multicenter investigated clinical echocardiographic up 1 year 165 consecutive who underwent TTVA (characterized by...
Background The tricuspid annular plane systolic excursion (TAPSE) assessed by echocardiography has failed in predicting outcomes patients with severe regurgitation (TR) undergoing transcatheter valve intervention (TTVI). Considering the complex shape of annulus and right ventricle, as well difficult echocardiographic image acquisition heart, cardiac computed tomography (CT) might be superior for analysis excursion. Thus, this study aimed to analyze whether CT-captured TAPSE provides...
The GLIDE Score is an anatomical scoring system designed to predict moderate residual tricuspid regurgitation (TR) immediately following transcatheter edge-to-edge repair (T-TEER). purpose of this study was evaluate the Score's predictive capability for achieving a postprocedural TR grade mild or better. This retrospective analysis included 336 patients from multicenter registry who underwent T-TEER between January 2017 and November 2022. Anatomical features were assessed using...
The aim of this study was to identify factors predisposing lung infarction in patients with pulmonary embolism (PE).We performed a retrospective analysis on 154 the final diagnosis PE being examined between January 2009 and December 2012 by means Toshiba Aquilion 64 CT scanner. severity clinical symptoms defined index 4 classes. clot load quantified using modified as proposed Miller. We correlated several potential predictors such demographic data, burden, distance total vascular obstruction...
To define the indications and contraindications for balloon dacryocystoplasty.Eighty-five patients with severe epiphora due to partial (n = 47) or complete 38) obstruction of nasolacrimal duct (NLD) were treated dacryocystoplasty (DCP). Steerable micro-guide wires flexible tips used. Success rates DCP evaluated clinically dacryocystographically during acute phase at 6- 12-month follow-up. Failures recurrences correlated clinical dacryocystographic treatment.Recanalization was successful in...
To evaluate the technical success, clinical outcome and safety of percutaneously placed totally implantable venous power ports (TIVPPs) approved for high-pressure injections, to analyse their value arterial phase CT scans.Retrospectively, we identified 204 patients who underwent TIVPP implantation in forearm (n=152) or chest (n=52) between November 2009 May 2011. Implantation via an upper arm (forearm port, FP) subclavian vein (chest CP) was performed under sonographic fluoroscopic guidance....
5-aminoimidazole-4-carboxamide-1-β-D-ribofuranoside (AICAR) is an established pharmacological activator of AMP-activated protein kinase (AMPK). Both, AICAR and AMPK were reported to attenuate inflammation. However, known for many AMPK-independent effects, although the mechanisms remain incompletely understood. Here we report a potent suppression lipopolysaccharide (LPS)-induced inflammatory gene expression by in primary human macrophages, which occurred independently its conversion...
Summary Since the introduction of multislice CT scanners, angiography (CTA) has become a powerful tool for imaging vascular system. We compare conventional to CTA in diagnosis morphological changes abdominal aorta and its branches. A retrospective analysis 52 patients who underwent both (MSCTA) digital subtraction before surgical treatment is presented. All examinations were performed after administration 100 mL contrast medium with collimation 4 × 1 mm pitch 7. standardized evaluation...
Anthracosis often results in mediastinal nodal enlargement. The aim of this comparative study was to evaluate if it is possible differentiate endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) proven anthracotic lymph nodes from malignant node enlargement by means multislice computed tomography (MSCT).We compared the MSCT findings 89 enlarged due anthracosis with 54 (non-small cell lung cancer 75.9%, small 18.5%, and non-Hodgkin lymphoma 5.6%). were assessed for...
To evaluate the frequency of enlarged hilar or mediastinal lymph nodes in patients suffering from chronic obstructive pulmonary disease (COPD).In a retrospective study, 89 with proven COPD were analysed. Exclusion criteria history malignant clinical evidence pneumonia. Prevalence, size, and localisation assessed by multi-slice computed tomography (MSCT) correlated stages following GOLD classification as well MSCT findings bronchitis emphysema.44/89 (49%) our showed nodes. Lymph node...
Purpose To identify risk factors for the development of catheter-related thrombosis (CRT) in patients with totally implant-able venous access ports (TIVAP) forearm, and to analyze effect prophylaxis treatment. Methods We retrospectively identified 200 (94 men, 106 women, mean age 57.7 +/-14 y) TIVAP implantation forearm between 3/2010 11/2010. Type, number punctures sonographically defined diameter accessed vein were analyzed. Chemotherapy administered prior procedure history thrombo-embolic...
