Delivery Catheter Capsule Demolition During the Deployment of a Medtronic CoreValve Evolut R

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.

Medtronic Corevalve

Transcatheter aortic valve replacement (TAVR) has been increasingly used to treat patients with symptomatic aortic stenosis. Despite the evolution of the valves and their deployment, patients that have undergone TAVR continue to be at high risk for major adverse events following the procedure. We recently reported that TAVR elicits a thromboinflammatory state that may contribute to the observed post-procedural thrombocytopenia associated with worse clinical outcomes. With the approval of the newer generation valves and delivery systems, we have now compared thromboinflammatory responses in patients receiving the Medtronic CoreValve and Edward’s new SAPIEN XT valve. Blood cell numbers, platelet function, and biomarkers of systemic inflammation and thrombosis were analyzed in 34 sequential patients undergoing transcatheteraortic valve replacement with the Edward’s SAPIEN XT valve or the Medtronic CoreValve Following valve deployment, platelet count, platelet activity, and platelet factor 4 levels decreased, while the inflammatory marker interleukin-6 increased. There were no significant differences in any of the parameters between the two valve types. Interestingly, baseline inflammation status predicted the extent of thrombocytopenia observed in overall cohort. A comparions of the SAPIENT XT valve and the Medtronic CoreValve reveals that the new generation valves generate a lower inflammatory response than that observed in the older SAPIEN valce. Importantly, our results add to the growing body of literature that suggests the thromboinflammatory changes that occur early after TAVR may predict long-term outcomes and suggest potential beneficial effects of an anti-inflammatory strategic.
