The optimal treatment of intermediate-high-risk pulmonary embolism (PE) remains unknown.To assess the effect conventional catheter-directed thrombolysis (cCDT) plus anticoagulation vs monotherapy in improving echocardiographic measures right ventricle (RV) to left (LV) ratio acute PE.The Catheter-Directed Thrombolysis Anticoagulation Patients with Acute Intermediate-High-Risk Pulmonary Embolism (CANARY) trial was an open-label, randomized clinical patients PE, conducted 2 large...
BACKGROUND Although Heller myotomy is one of the most effective treatments for achalasia, it may be associated with early or late symptom relapse in some patients. Therefore, additional treatment required to achieve better control symptoms.To evaluate safety and efficacy pneumatic balloon dilation (PBD) patients after myotomy. METHODS Thirty six post-myotomy were evaluated from 1993 2013. Six excluded analysis because comorbid diseases epiphrenic diverticula. treated PBD. Primary outcome was...
Background:Interrupted aortic arch (IAA) is a rare congenital malformation of the arch, which might be accompanied with other coexisting cardiovascular anomalies. Case Report:Many cases IAA are diagnosed at their neonatal and newborn period but in diagnosis not established until adulthood.The patients may have no clinical symptoms signs heart failure will gradually appear cause death. Results:The development imaging methods such as computed tomography (CT) magnetic resonance (MR) has...
To develop an ameliorated sirolimus (SIR) liposome for intramural delivery, the effects of various carrier physicochemical parameters on antirestenosis efficacy were evaluated.Different liposomes prepared, characterized and administered to balloon injured rats (12 animal groups). Their efficacies investigated using morphometric, immunohistochemical in vivo computed tomography imaging analyses.The SIR decreased following order: cationic 100 nm vesicles ≥ 60 > neutral stealth anionic vesicles....
Although hydatic cyst disease rarely involves myocardium and endocardium, cardiac echinococcosis, a potentially life‐threatening condition, should be managed promptly. We report case of right ventricle hydatid detected after syncopal attack in pregnant woman by using echocardiography .
Idiopathic achalasia (IA) is a primary motor disorder of the esophagus. Recently, ethanolamine oleate (EO) has been introduced as novel therapy in IA. We investigate long-term efficacy EO injection selected IA patients. Two hundred twenty patients with were evaluated prospectively. Thirty-one who resistant to or poor candidate pneumatic balloon dilation and/or cardiomyotomy enrolled this study. was injected into lower esophageal sphincter three times at 2-week intervals. Patients symptom...
Microbubbles are broadly used as ultrasound contrast agents. In this paper we use a low-cost flow focusing microchannel fabrication method for preparing microbubble agents by using some surface active and viscosity enhancing material to obtain appropriate microbubbles with desired lifetime stability any in vitro infusion velocity measurement. All the five parameters that govern bubble size extract efforts done achieve smallest bubbles adding suitable surfactant concentrations. By these...
Background/aim: The prognostic value of the red cell distribution width (RDW) as a cost-effective and noninvasive test in acute pulmonary embolism (PE) is still unknown. We aimed to investigate admission RDW level long-term survival PE patients. Materials methods: In this registry-based, prospective cohort study, total 378 patients (mean age: 60.4 ± 17.11 years, 47.4% female) who presented with were enrolled. All clinical data for each patient obtained from our institutional registry....
Finite element models for estimation of intraoperative brain shift suffer from huge computational cost. In these models, image registration and finite analysis are two time-consuming processes.The proposed method is an improved version our previously developed Element Drift (FED) algorithm. this work the process combined with analysis. Combined FED (CFED), deformation whole mesh iteratively calculated by geometrical extension a local load vector which computed FED.While processing time...
Acute pulmonary embolism (PE) is a cardiovascular challenge with potentially fatal consequences. This study was designed to observe the association of novel cardiac biomarkers outcome in this setting. In prospective study, from 86 patients confirmed diagnosis PE, 59 met inclusion criteria (22 men, 37 women; mean age, 63.36±15.04 y).The plasma concentrations N-terminal pro-brain natriuretic peptide (NT-proBNP), growth differentiation factor-15 (GDF-15), heart-type fatty acid-binding protein...
Abstract Few cases of a floating thrombus in normal aorta have been reported without other underlying reasons for the formation and its systemic embolic complications. We report case which proximal aortic arch was detected after echocardiography computed tomography angiography as an origin upper extremities ophthalmic embolism.
COVID-19 causes significant hypoxia along with an exacerbated inflammatory milieu, which may be a trigger for atherosclerotic plaque rupture and/or thromboembolic events. Herein, we presented case of acute coronary syndrome followed by pulmonary thromboembolism and cerebrovascular accident.
The association between osteoporosis, a common metabolic bone disorder, and atherosclerosis has been reported in different studies. In this study, we aimed to investigate the coronary artery calcium score (CACS) mineral density (BMD) at sites biomarkers postmenopausal women.A total of 184 participants were enrolled study. CACS BMD sites, including spinal, hip, femoral neck, measured using computed tomography angiography dual energy X-ray absorptiometry, respectively. Serum levels...
