Brief summary

A prospective clinical evaluation of the effectiveness of the Ovation Alto Abdominal Stent Graft System when used in the treatment of subjects with abdominal aortic aneurysm (AAA).

Detailed description

A prospective clinical evaluation of the effectiveness of the Ovation Alto Abdominal Stent Graft System when used in the treatment of subjects with abdominal aortic aneurysm (AAA). The primary objective is to evaluate treatment success at 12 months with the Ovation Alto Abdominal Stent Graft system. The study will have up to 16 sites, and up to 75 patients based on attrition rates. The follow-up intervals will be at 1, 6, and 12 months following initial implant procedure.

Primary

MeasureTime frameDescription
Number of Subjects With Treatment Success12 monthsTreatment success is defined as technical success, freedom from type I and III endoleaks at 12 months, freedom from stent graft migration \> 10m at 12 months compared to 1 month baseline, freedom from AAA enlargement \>5mm at 12 months (compared to 1-month baseline, freedom from AAA rupture through 12 months, freedom from conversion to open repair through 12 months, stent graft stenosis, occlusion or kink requiring secondary intervention through 12 months, thromboembolic event attributable to stent graft requiring secondary intervention through 12 months, stent fracture requiring secondary intervention through 12 months.

MeasureTime frameDescription

Number of Participants With AAA Enlargement > 5mm6 months, 12 monthsChange in aneurysm diameter greater than 5mm
Number of Participants With AAA Rupture30 day, Day 31-365A tear in the abdominal aorta that can result in serious internal bleeding.
Number of Participants With Conversion to Open Repair30 day, Day 31-365conversion to open abdominal surgery to repair AAA

Number of Participants With AAA-related Mortality1 month, Day 31-365death caused by or related to AAA
Event Rates for Endoleaks1 month, 6 months, 12 monthsEndoleak is defined by the persistence of blood flow outside the lumen of the endovascular graft but within the aneurysm sac and can be classified as: * Type I - Ineffective seal at either the proximal or distal sealing zones * Type IA - Ineffective seal at the proximal sealing zone * Type IB - Ineffective seal at the distal sealing zone * Type II - Retrograde blood flow from lumbar arteries, the inferior mesenteric artery, or other collateral vessels into the aneurysm sac * Type III - A leak caused by fabric tears or disruption, component disconnection, or graft disintegration * Type IIIA - Junctional leak or component disconnection * Type IIIB - Midgraft hole * Type IV - Blood flow through an intact fabric. * Unknown endoleak - Endoleak present but unable to assess type Endoleak will only be evaluated as an adverse event or serious adverse event if it is present at the 30-day follow-up visit or if a post-index procedure re-intervention occurs.
Major Adverse Events1 yearMajor adverse events (MAE) are defined as any one of the following events: * Death * Myocardial Infarction * Stroke (excludes TIA) * Renal Failure (excludes renal insufficiency) * Respiratory Failure (excludes chronic obstructive pulmonary disease (COPD) or pulmonary complications) * Paralysis (excludes paraparesis) * Bowel Ischemia * Procedural Blood Loss (≥1,000 cc)
Number of Participants With Other Stent Graft Finding (Includes Kinking and Stent Compression)1 month, 6 months, 12 monthsThe integrity of the stent graft is evaluated by the Independent Core Lab via abdominal X-rays at regularly scheduled follow-up visits. Any fractured stents, and any other issues compromising the integrity of the stent graft will be reported.
Number of Participants With Stent Fracture1 month, 6 months, 12 monthsThe integrity of the stent graft is evaluated by the Independent Core Lab via abdominal X-rays at regularly scheduled follow-up visits. Any fractured stents, and any other issues compromising the integrity of the stent graft will be reported.
Adverse Events (Serious and Non-serious)30 days, Day 31-365An adverse event is any new, undesirable medical occurrence or change (worsening) of a pre-existing condition that occurs in a subject, whether or not considered to be associated with the product
Procedure-related Adverse Event30 days, Day 31-365Procedure-Related event is caused or contributed by the initial study device implantation (index) procedure, up to 30 days, unless a different etiology can be identified
Serious Adverse Event30 Days, Day31-365)A serious adverse event (SAE) defined as one that suggests a significant hazard or side effect, regardless of the investigator or Sponsor's opinion on the relationship to the investigational product. This includes, but may not be limited to, any event that: * Is fatal * Is life-threatening * Requires or prolongs (\>48 hours) inpatient hospitalization * Is a persistent or significant disability or incapacity * Is considered an important medical event
Device-related Adverse Events (AEs)30 days, Day 31-365Device-Related: Event is caused or contributed by any component of the device during delivery, deployment or while the device is in situ post-operatively

Number of Subjects With Treatment Success

Treatment success is defined as technical success, freedom from type I and III endoleaks at 12 months, freedom from stent graft migration \> 10m at 12 months compared to 1 month baseline, freedom from AAA enlargement \>5mm at 12 months (compared to 1-month baseline, freedom from AAA rupture through 12 months, freedom from conversion to open repair through 12 months, stent graft stenosis, occlusion or kink requiring secondary intervention through 12 months, thromboembolic event attributable to stent graft requiring secondary intervention through 12 months, stent fracture requiring secondary intervention through 12 months.

Time frame: 12 months

Population: 61 subjects were evaluable at 1 year- evaluable meaning able to be assessed for all items of composite endpoint of treatment success; 67 subjects completed 1 year, however, some of these subjects did not have imaging or imaging was not evaluable.

Event Rates for Endoleaks

Endoleak is defined by the persistence of blood flow outside the lumen of the endovascular graft but within the aneurysm sac and can be classified as: * Type I - Ineffective seal at either the proximal or distal sealing zones * Type IA - Ineffective seal at the proximal sealing zone * Type IB - Ineffective seal at the distal sealing zone * Type II - Retrograde blood flow from lumbar arteries, the inferior mesenteric artery, or other collateral vessels into the aneurysm sac * Type III - A leak caused by fabric tears or disruption, component disconnection, or graft disintegration * Type IIIA - Junctional leak or component disconnection * Type IIIB - Midgraft hole * Type IV - Blood flow through an intact fabric. * Unknown endoleak - Endoleak present but unable to assess type Endoleak will only be evaluated as an adverse event or serious adverse event if it is present at the 30-day follow-up visit or if a post-index procedure re-intervention occurs.

Time frame: 1 month, 6 months, 12 months

Population: All available data has been analyzed; due to imagining requirements and quality of imaging, all patients present for visit may not have been evaluable per definitions.
