Abstract Background: Communication between the right pulmonary artery (RPA) and left atrium (LA) is a rare cause of central cyanosis in pediatric patients. Case presentation: We describe a 3-year-old female patient with an oxygen saturation of 70% at admission. The echocardiogram indicated an abnormal color flow Doppler in the LA and she underwent standard cardiac catheterization. The angiography of pulmonary artery revealed a 7.4 mm × 7.6 mm fistula between the RPA and LA and achieved successful closure using ventricular septal defect occlusion. Conclusion: The fistula between pulmonary artery and left atrium is an extremely rare but treatable More >

Abstract Marfan syndrome patients have connective tissue abnormalities that predispose them to intracardiac defects and postoperative complications. We present a case of late onset ASD device failure secondary to device movement within the atrial septum in a girl with Marfan syndrome. This case study suggests that further studies are necessary to determine the optimal device and approach for ASD repair in this patient cohort. More >

Abstract Introduction: To improve the success rate and safety of ureteral stent insertion, we sought to identify the effect of guidewire type and prior use upon the force needed to advance a 6Fr ureteral stent over various guidewires.
Materials and methods: Two hundred forty stent insertion trials were performed in an ex vivo porcine urinary tract model. Ten trials were randomly performed over 12 new and 12 used guidewires. For each trial, the force required to advance a 6Fr Cook double-pigtail ureteral stent was recorded. Guidewires included the Olympus Glidewire, Cook Fixed Core, and Boston Scientific Amplatz Super… More >

Abstract Introduction: We sought to investigate whether starting clean intermittent catheterization (CIC) for multiple sclerosis (MS) patients with lower urinary tract symptoms (LUTS) and elevated post-void residual (PVR) would improve urinary quality of life (QoL) and decrease risk of urinary tract infection (UTI).
Materials and methods: We retrospectively reviewed an institutional database for MS patients with PVR > 100 mL and obstructive LUTS. Patients were categorized by subsequent choice of treatment: CIC versus medical treatment. Outcomes compared over 1-year follow up included incidence of UTI, urinary QoL, emergency room visits, and adherence to therapy.
Results: Between 2014 and 2017,… More >

Abstract Introduction: Continence and catheter-related pain following prostatectomy are significant patient concerns, and it is unknown whether catheter size impacts these variables. In this study, patients undergoing prostatectomy were randomized to receive either a 16 French or 20 French catheter to assess the impact of catheter size on postoperative continence and pain.
Materials and methods: Patients were prospectively randomized to receive either a 16 French or a 20 French latex catheter at the completion of prostatectomy. Subjects were asked on postoperative day 7 to report their average catheter-related pain and the amount of opioid medication used. International Prostate… More >

Abstract The blood flow through a catheterized artery having a mild stenosis at the wall together with a blood clot at the centre is studied in the current investigation. Stenosis can occur in vessels carrying blood to brain (i.e., Carotid arteries), Renal arteries that supply blood to kidneys etc. The flow is refined in such vessels by application of catheter. We have used a Newtonian viscous fluid model and also distinct shapes of stenosis, (i.e., symmetric and non-symmetric shapes) are considered for this study. The entropy generation together with viscous dissipation is also taken into account… More >

Abstract Background: Trans-catheter closure has become the treatment of choice for patent foramen ovale (PFO) and ostium secundum atrial septal defects (ASD). A wide variety of devices are commercially available, however, concerns have been raised about the risk of cardiac erosion associated with stiff/rigid devices. The GORE® CARDIOFORM Septal Occluder (GSO) is a double-disc, soft and conformable device with no reported incidence of cardiac erosions. However, wire frame fracture (WFF) have been reported. Aim: To assess the incidence and clinical significance of WFF after GSO implantation in paediatric patients. Methods: Seventy-seven consecutive patients were enrolled. Periprocedural and follow-up… More >

Abstract Background: Transcatheter closure of secudum atrial septal defect (ASD) has gained wide acceptance since its introduction more than 3 decades ago. Safety and efficacy of the procedure in everyday practice needs continuous update. Objective: The aim of the study is to determine the incidence of complications and identify everyday management protocols. Methods: This is a prospective nonrandomized study including all the patients with Secundum ASD or fenestrated IAS referred to two different congenital heart diseases centers in Ain Shams university and sohag university in Egypt over 2 years with an indication for closure according to American and… More >

Abstract Coronary artery fistulae (CAFs) are anomalous connections that bypass the myocardial capillary bed between 1 or more coronary arteries and other cardiac chambers or other vessels. These fistulae are usually asymptomatic and are, thus, diagnosed incidentally. However, larger CAFs can cause various symptoms such as angina, exertional dyspnea, syncope, palpitation, and even sudden cardiac death. Treatment options include surgical closure and percutaneous transcatheter closure (TCC) with comparable safety and efficacy. The choice of device in TCC depends on the anatomic characteristics of the CAF, the age and size of the patient, the size of the More >

Abstract The world-wide impact of traumatic injury and associated hemorrhage on human health and well-being is significant. Methods to manage bleeding from sites within the torso, referred to as non-compressible torso hemorrhage (NCTH), remain largely limited to the use of conventional operative techniques. The overall mortality rate of patients with NCTH is approximately 50%. Studies from the wars in Afghanistan and Iraq have suggested that up to 80% of potentially survivable patients die as a result of uncontrolled exsanguinating hemorrhage. The commercially available resuscitative endovascular balloon occlusion of the aorta (REBOA) is a percutaneous device… More >
