Detailed Description
The advent of endovascular, transcatheter aortic valve replacement (TAVR), and mechanical circulatory support has offered new, minimally invasive therapeutic options that are rapidly becoming standard of care. These percutaneous transfemoral interventions require large-bore catheters and have created challenges for femoral arterial access management. Current approaches include surgical cut-down with arterial puncture under direct vision, and suture-based "pre-closure." Surgical cut-down is associated with longer procedural time, increased patient discomfort, deeper anesthesia, risk of wound complications including infection, and slower ambulation. The pre-closure technique overcomes many of the disadvantages of surgical cut-down but can be technically demanding, time consuming, and associated with a significant failure rate. Recent randomized TAVR trials have reported major vascular complications in 6% to 8% . Furthermore, a study on the 2 suture-based closure techniques for management of TAVR access reported a 20% vascular complication rate despite being used by experienced operators . Currently, the majority of access site complications result from failed arteriotomy closure . The percutaneous MANTA Vascular Closure Device (VCD) (Essential Medical Inc., Malvern, Pennsylvania) is a novel collagen-based technology dedicated to closure of largebore arteriotomies . The MANTA VCD underwent prospective multicenter evaluation for Conformitä Europäenne (CE) mark approval in the first detailed report of outcomes achieved with a dedicated large-bore vascular closure device Contrary to the aforementioned TAVR procedures, mechanical circulatory support therapy can be extended up to several days on the intensive care ward. Data on such delayed closure with is lacking. This registry is therefore aimed to document the initial experiences of delayed closure of a femoral large bore access with vascular closure devices in patients with an TAVR device.
