VIenna Pilot Study for Automated Annular Suturing Technology (VIP-RAM)

December 2, 2020 updated by: Martin Andreas, M.D., Medical University of Vienna

VIenna Pilot Study for Automated Annular Suturing Technology to Assist in Aortic & Mitral Valve Replacement - A Single-center Clinical Safety & Feasibility Pilot Trial

The objective of this study is to compare surgical outcomes between patients who underwent valve replacement with and without the help of the automated annular suturing technology. In addition, data of the early and intermediate postoperative period will be collected within routine clinical follow-up in order to assess morbidity and mortality as well as echocardiographic parameters.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study is a clinical, single-center pilot-study to evaluate safety and performance. 30 Patients (n=20 aortic valve replacement/ n=10 mitral valve replacement) with aortic and mitral valve pathology, highly likely for prosthetic valve replacement, who are planned for surgery at the Vienna General Hospital (AKH) will be included in this study with respect to the inclusion and exclusion criteria. The patients will undergo aortic or prosthetic mitral valve replacement using a specified automated annular suturing system for placement of the annular pledgeted sutures.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: surgical aortic valve replacement
n=20 patients with aortic valve pathology and indication for surgical aortic valve replacement
Procedure: automated annular suturing
RAM® Automated Suturing Technology. The RAM® DEVICE and SEW-EASY® DEVICE are automated suturing devices indicated for use in the approximation of soft tissue and prosthetic materials when used in conjunction with RAM® COR-SUTURE® QUICK LOAD® surgical suture. Devices will be used for the approximation of respective replacement valves during surgical aortic or mitral valve replacement as described in the study protocol. Cases may include use of the RAM® RING/RAM® RACK devices for suture management and the Aortic Root Retractor (ARR) with delivery device.
Other: surgical mitral valve replacement
n=10 patients with mitral valve pathology and indication for surgical mitral valve replacement
Procedure: automated annular suturing
RAM® Automated Suturing Technology. The RAM® DEVICE and SEW-EASY® DEVICE are automated suturing devices indicated for use in the approximation of soft tissue and prosthetic materials when used in conjunction with RAM® COR-SUTURE® QUICK LOAD® surgical suture.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Freedom from mortality at 30 days post-OP assessed by clinical follow-up reports.
Time Frame: 30 days post surgical valve replacement
Follow-ups 30 days post-OP are performed and freedom from mortality evaluated.
30 days post surgical valve replacement
Implantation time assessed by surgical report.
Time Frame: procedural
Implantation time, the duration defined from start of the valve assessment until the completion of the prosthesis implantation (defined as fixation of the last suture) assessed by surgical report.
procedural

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Freedom from severe adverse events at 30 days post-OP assessed by clinical follow-up reports
Time Frame: 30 days post surgical valve replacement
Follow-ups 30 days post-OP are performed to and freedom from severe adverse events evaluated.
30 days post surgical valve replacement
Surgical times assessed by surgical report.
Time Frame: procedural
Surgical times, aortic cross-clamp time and cardiopulmonary-bypass time, assessed by surgical report.
