Abstract Background Right ventricular (RV) septal pacing is often selected to preserve a more physiologic ventricular activation. But the pacing leads are not always located in true septal wall, rather in hinge or free wall in some cases with the conventional stylet-guided lead implantation. In recent years, new guiding catheter systems has attracted attention as a solution to that problem. Objective The aim of this study is to investigate that true ventricular sepal pacing can be achieved by use of the new guiding catheter system for pacing lead. Methods We enrolled 198 patients who underwent RV septal lead implantation and computed tomography (CT) after pacemaker implantation. 16 cases were used delivery catheter (Delivery), and 182 cases were used stylet for targeting ventricular septum (Conventional). We analyzed the lead locations with CT, and evaluated capture thresholds, R-wave amplitudes, lead impedances and 12-lead electrocardiogram findings one month after implantation. Results All cases of delivery catheter group had true septal lead positions (Delivery; 100% vs Conventional; 44%, p<0.01). Capture thresholds and lead impedances had not significant differences between between two groups (0.65±0.15V vs 0.60±0.15V, p=0.21, 570±95Ω vs 595±107Ω, p=0.39, respectively). R-wave amplitudes were significantly higher in delivery catheter group (13.0±4.8mV vs 10±4.6mV, p<0.01). Paced QRS durations were shorter in delivery catheter group (128±16ms vs 150±21ms, p<0.01). Conclusions The delivery catheter system designated for pacing lead can contribute to select the true ventricular septal sites and to attain the more physiologic ventricular activation.

Abstract Transcatheter device closure of an atrial septal defect (ASD) may require an additional supportive technique in challenging cases. We report a 15-year-old male with moderate-sized ASD and severe scoliosis. In spite of adequate positioning of the Gore Cardioform ASD occluder, the device was pulled into the right atrium by a retrieval cord due to the acute release of strong tension between the delivery catheter and its device upon locking. This phenomenon was prevented by the use of Mullins sheath, resulting in a successful release of the device. The use of a Mullins sheath may be considered to deliver a Gore Cardioform ASD device in selected cases.

Purpose To conduct a pilot study to demonstrate a novel method of using a proprietary cyanoacrylate (CA) for closure of superficial veins. Materials and Methods Right and left superficial epigastric veins from two swine models were utilized due to the vein's similarities with the human great saphenous vein. Under ultrasound guidance, access was gained and a 5-F delivery catheter was advanced to the junction of the superficial epigastric and abdominus rectus veins. A dispenser gun was then utilized to inject 0.16 mL of CA while compression was applied cephalad to the end of the catheter. Immediately after delivery, the catheter was pulled back 3 cm and manual compression was employed for 30 seconds. After this first injection, the ultrasound probe was repositioned caudad to the injection and cephalad to the catheter tip and another 0.16 mL injection was delivered with immediate 3 cm pullback of the delivery system. Manual compression was applied at the caudad end of the treated vein for 30 seconds. This process was repeated until the entire target segment was treated. Results At 30 days postimplantation, the treated veins were occluded with no evidence of recanalization or migration. Histological findings revealed that the lumen was dilated by coalescing, arborizing clear spaces with entrapped lytic erythrocytes, demarcated by a thin band of granular eosinophilic material. Spindle cells with dense eosinophilic matrix replaced the tunica intima and disrupted the tunica media. Conclusion Results of this initial study demonstrated that intravascular injection of CA is feasible for closure of superficial veins in animal models. These findings warrant further animal studies of this proprietary CA to assess efficacy, safety and its effects on perivenous structures.

Abstract Background Esophageal perforation is an emergency condition characterized by high morbidity and mortality. The removable esophageal stent is an effective method of treatment in cases with esophageal perforation as they allow minimal invasive and rapid nutrition. Stent migration is an important problem in perforations and fistulas where there is no obstruction in the esophageal lumen. Several methods are used to prevent stent migration, including different stent types and endoscopic suture technique. In this study, we aimed to present a method that we use in our clinic to prevent stent migration. Methods We retrospectively evaluated 12 consecutive patients who underwent stent placement and were fixed for migration prevention for esophageal fistula or perforation between January 2013 and February 2018 in our clinic. All of the cases were self-expandable metallic stents. The stent was removed from the delivery catheter without insertion and the suture material was passed through the head and reattached to the catheter. The stent was placed using flexible endoscopy. The suture material placed on the upper part of the stent was taken out of the mouth of the patient. After the stent is inserted and the delivery catheter is removed, the nasal catheter (aspiration catheter) was inserted and removed from the mouth. The suture material in the mouth was connected to the tip of the aspiration catheter. The aspiration catheter was withdrawn. The suture material removed from the patient's nose was fixed like a nasogastric catheter. After 3 or 4 days from the procedure, the suture was cut. Migration of the stent was followed by direct radiography. Results Seven cases were female and five cases were male. The mean age was 51.1 ± 12.7 years (range 20–72 years). No migrations were observed in any of the cases. After a mean of 19.5 days (range 11–23 days), the stent was removed endoscopically. In all cases, perforation and fistula improved. Conclusion We think that the esophageal stent fixation method is a simple and effective method to prevent migration. Disclosure All authors have declared no conflicts of interest.
