Abstract
INTRODUCTION Microcatheters and microcoils are produced by a number of different companies, and this is one of the reasons that their compatibility is sometimes unclear. Therefore, we conducted an experimental study to evaluate the compatibility of microcoils through major microcatheters using an in vitro model. MATERIAL AND METHODS We performed trials on eight types of microcoils with 16 types of microcatheters in a vascular model under fluoroscopy. The microcatheters were perfused with normal saline and the vascular model with normal saline with lubricant during the experiment. Two radiologists evaluated their compatibility with scores of 1 through 5 in a double-blinded state (1: not passable, 2: passable with exertion, 3: passable with some resistance, 4: passable with slight resistance, and 5: passed without resistance). RESULT A total of 512 combinations were examined. The number of scores with 5, 4, 3, 2, and 1 were found for 465, 11, 3, 2, and 15 combinations, respectively. Sixteen combinations were non-applicable due to the depletion of microcoils. CONCLUSION Although this experiment has multiple limitations, most microcoils and microcatheters are compatible if their primary diameters are smaller than the indicated microcatheter tip inner diameters, with some exceptions.

Abstract
BACKGROUND The Cocoon septal occluder (CSO) is a new generation double disk occluder device for catheter closure of the secundum atrial septal defect (ASD). Initial clinical evaluations with the use of this device have shown quite satisfactory results but large follow-up studies are missing. In this international multicenter study, we present procedural and follow-up data from 4008 patients with secundum ASD who underwent catheter closure with the use of CSO. METHODS The study cohort consisted of 1853 pediatric and 2155 adult patients with secundum ASD treated with the CSO. Patients were enrolled retrospectively from 11 international centers and were followed for a mean period of 43 months (range 12-84 months), postprocedural. Clinical, electrocardiographic, echocardiographic, procedural, and follow-up data were collected from each collaborating hospital. RESULTS The CSO was permanently implanted in 3983 patients (99.4%). Echocardiographic evaluation at one month follow-up revealed complete closure in 99.6% of those patients who had a device implanted. Thrombus formation in one adult patient was the only major device related to procedural complication. During the follow-up period, no patient developed cardiac erosions, allergic reactions to nickel, or other major complications. CONCLUSIONS Implantation of CSO provided satisfactory procedural and follow-up results with high success and no device-related cardiac erosions and nickel allergy.

Abstract
Duct dependent aortic arch obstruction with borderline left ventricular hypoplasia presents a diagnostic dilemma. If the left ventricle (LV) is adequate to sustain systemic cardiac output without a patent duct, arch obstruction is relieved surgically and duct is divided. Inadequate LVs do not tolerate duct division, and these patients need more complex Norwood type surgeries. However, catheter-based interventions for arch obstruction can retain ductal patency. The progressive changes in anatomy and physiology of a neonate who presented with hypoplastic left heart structures and patent duct with advancing age and modified by serial catheter-based interventions are presented to highlight the use of interventions in this therapeutic dilemma.

Abstract
INTRODUCTION Air in extracorporeal membrane oxygenation circuit may lead to deleterious consequence. CASE REPORT Three cases of air in extracorporeal membrane oxygenation were presented. Air was introduced from right jugular venous sheath during percutaneous septal repair, pulmonary artery catheter during intensive care unit, and sewing holes on atrial wall during surgery respectively. Accidents in Case 2 and Case 3 were successfully managed, while Case 1 was suspected of cerebral air embolism through transseptal right-to-left shunt. DISCUSSION With extracorporeal membrane oxygenation being widely applied in more clinical settings, especially in catheterization lab, risks of air in extracorporeal membrane oxygenation increase. More attention should be paid to patients with communication between right and left heart system, especially in situations when venous accesses' exposure to air could not be avoided. CONCLUSION Air in the extracorporeal membrane oxygenation circuit should never be overemphasized, especially during special procedures.

Abstract
Objective: To examine the clinical characteristics of fluid collections after pancreatic surgery and evaluate the safety and effectiveness of CT-guided percutaneous catheter drainage (CT-PCD).Material and methods: A retrospective, cross-sectional study was carried out. 51 patients enrolled in this study underwent CT-PCD for collections after pancreatic surgery. The clinical and imaging data were collected and analysed.Results: In all 51 cases, CT scans showed that the samples were collected from the upper abdomen in 94.1% (48/51) of the patients. Apparent clinical symptoms before puncture manifested in 88.2% (45/51) of the patients. The average interval between surgery and puncture was 14.3 ± 7.9 days. In 76.4% (39/51) of the patients, the abdominal drainage catheter inserted during surgery was still not removed during CT-PCD. Amylase levels in drainage fluid were more than three times that of serum amylase in 66.7% (24/36) of the patients. The drainage fluid of 37 patients was sent for bacterial cultures; of these, 64.9% (24/37) tested positive. Full recovery after single puncture procedure occurred in 84.3% (43/51) of the patients. The incidence of puncture-related complications was 3.9%.Conclusions: Pancreatic postoperative collections requiring clinical puncture were mostly located in the upper abdomen. CT-PCD is a safe technique with good therapeutic effects in patients with collections.

Abstract
The treatment of children with congenital heart defects has evolved in the last 60 years from conservative care to a highly specialized management where advances in imaging, surgical, interventional and support techniques meet together to ensure satisfactory development and good quality of life to the child and to the upcoming grown up. Management of congenital heart defects best begins before birth with the aim, whenever possible, to maintain or establish biventricular physiology or, if this is excluded, to optimize the conditions for univentricular physiology. Current research in the field of genetics, device bioengineering and miniaturization, stem cell therapy, and fusion imaging technology is expected to help to improve further patient outcome. In this review, current management strategies and future prospects are discussed.

Abstract
The first interventional attempts at relieving mitral valve disease were in a sense minimally invasive, using relatively small incisions and introduction of instruments or a finger to open stenotic valves on the beating heart. The development of reliable cardiopulmonary bypass (CPB) made exact anatomic repair of mitral pathology possible with improved results. Mitral valve surgery on an arrested heart has been the mainstay of treatment for decades. Modifications and minimalization of the surgical approach using videoscopic or robotic instruments have made less invasive procedures possible. Such procedures demand excellent technical skills and are still not widely adopted. More recently, attempts have been made to repair mitral valves using endovascular access on the beating heart, guiding the repair process with real-time imaging. We are presenting a review of available and developing techniques for endovascular repair of the mitral valve. A device developed by our group will be briefly described.

Abstract
Transcatheter aortic valve implantation (T-AVI) has become the standard of care for high-risk patients suffering from severe aortic valve stenosis. More than 60,000 implants have been performed to date. While the first-generation T-AVI devices had some specific issues, the advancements in these first-generation devices and the development of second-generation devices significantly reduced the incidence of peri-procedural complications. The two major access routes are the transfemoral (TF) and the transapical (TA) approach. Both approaches have their advantages and should be considered equal alternatives for finding the best treatment option for the individual patient. Currently there are discussions about extending the indication to patients with lower risk profiles. However, there is no real evidence to justify an expansion, as results of surgical aortic valve replacement in low and intermediate risk patients are excellent.

Abstract
OBJECTIVE To evaluate the technical feasibility and safety considerations of balloon-occluded transarterial chemoembolization (B-TACE) using a newly developed 1.8-French (Fr) tip microballoon catheter for hepatocellular carcinoma (HCC). MATERIAL AND METHODS Between February 2013 and May 2013, 31 patients (20 males, 11 females; age range 56-85 years) underwent B-TACE using a 1.8-Fr tip microballoon catheter for unresectable HCC. The technical success rate, procedural complications, and adverse events of B-TACE were retrospectively investigated. RESULTS A total of 31 patients were subjected to 70 sessions of B-TACE using a 1.8-Fr tip microballoon catheter. The level of B-TACE was sub-subsegmental in 11, subsegmental in 35, segmental in 14, lobar in five, and right inferior phrenic artery in five sessions. The overall technical success rate was 99% (69 out of 70 sessions). As procedural complications, rupturing of the microballoon (n = 3) and aneurysmal dilatation at the site of balloon occlusion (n = 2) were encountered. There were no significant differences in any parameters between blood biochemical examination before and between two to four weeks after the procedure. CONCLUSION A 1.8-Fr tip microballoon catheter enables selective catheterization in patients with HCC and B-TACE using the 1.8-Fr tip microballoon catheter is a safe procedure.
