Prospective Clinical Registry Evaluating Contemporary MANTA Outcomes

Study Overview
=================
Brief Summary
-----------------
This is an observational study designed to evaluate the safety and clinical outcomes of the MANTA® Vascular Closure Device (VCD) (the MANTA® Device) in TAVR procedures. The study will enroll participants who are undergoing a TAVR procedure. The purpose of this study is to examine and collect data on outcomes of contemporary MANTA® large bore closure in standard of care (SOC) TAVR procedures with on-label use of the MANTA® device including appropriate patient selection and proper vascular access.

Detailed Description
-----------------
In the U.S. and Canada, the MANTA® Vascular Closure Device is indicated for closure of femoral arterial access sites while reducing time to hemostasis following the use of 10-20F devices or sheaths (12-25F OD) in endovascular catheterization procedures. In Israel, the 14F MANTA® is indicated for closure of femoral arterial access sites following the use of 10-14F devices or sheaths (maximum OD/profile of 18F), and the 18F MANTA® device is indicated for closure of femoral arterial access sites following the use of 15-18F devices or sheaths (maximum OD/profile of 25F). The purpose of the study is to examine and collect data on outcomes of contemporary MANTA® large bore closure in standard of care (SOC) TAVR procedures with on-label use of the MANTA® device including appropriate patient selection and proper vascular access.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Device: MANTA Vascular Closure Device|The MANTA® Vascular Closure Device consists of a 14F or 18F MANTA® Closure Device, a 14F or 18F Sheath with Introducer, and an 8F Depth Locator. In the U.S. and Canada, the MANTA® Vascular Closure Device is indicated for closure of femoral arterial access sites while reducing time to hemostasis following the use of 10-20F devices or sheaths (12-25F OD) in endovascular catheterization procedures.|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of VARC-3 Major & Minor Vascular complications |  | within 30 days of TAVR procedure | 
| Time to Hemostasis | The elapsed time between MANTA® deployment and first observed and confirmed arterial hemostasis | During the procedure | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Additional interventions: Required at large bore access site to address complications | The percentage of subjects with additional interventions required at large bore access site to address bleeding or other large bore access site complications (e.g., bare or covered stent or surgical repair), within 30 days following the procedure | within 30 days following the procedure | 
| Technical Success: | The percentage of subjects in whom closure is obtained with the MANTA® VCD without the use of unplanned endovascular or surgical intervention | During the procedure | 
| Ambulation Success: | The percentage of a previously ambulatory subjects (until day of TAVI) who are able to ambulate for at least 20 feet/6 meters without re-bleeding. | During procedure admission | 
| Treatment Success: | The percentage of subjects in whom the time to Hemostasis ≤10 minutes and have no Large Bore Access Related Major VARC-3 complications within 30 days. | within 30 days of TAVR procedure |
