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

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Experimental: Limited Right Anterior Thoracotomy
mitral valve replacement through minimal invasive approach
Procedure: mitral valve replacement through limited right anterior thoractomy
The incision is placed just lateral to the nipple over the fourth intercostal space (above the nipple in men and in the inframammary crease in most women) 6-10 cm in length, the pectoralis muscles are mobilized for fourth intercostal space thoracic entry-The pericardium is opened 2-cm ventral to the phrenic nerve under direct vision and carried cephalad to the aortic reflection. The anterior edge of the pericardium is tacked to incision edges using silk sutures-To initiate cardiopulmonary bypass, Cannulation of the femoral artery and femoral vein should be prior to mediastinal dissection-. The ascending aorta occluded with an external clamp. This aortic clamp passed through the thoracotomy incision if we use the aortic cross clamp and the anterograde cardioplegia delivered through a standard cardioplegia cannula secured with purse-string sutures in the ascending aorta.
Active Comparator: median sternotomy
mitral valve replacement through traditional median sterntomy approach
Procedure: mitral valve replacement through median sterntomy
The incision is begun approximately 2 cm below the sternal notch and extended approximately 2 cm beyond the distal tip of the xiphoid process and is usually extended with the electrocautery down to the sternal periosteum. A midline approach can be ensured by careful attention to the insertion points of the pectoralis major muscles onto the sternum; the incision should lie directly midway between these insertion points.After sternotomy, the pericardium is opened; the heart is cannulated for cardiopulmonary bypass. Arterial inflow is established by cannulation of the distal ascending aorta near the pericardial reflection. Double venous cannulation of the venae cavae by way of the right atrium is generally employed. In most adults a size 32 Fr cannula in the superior vena cava and a size 34-38 Fr cannula in the inferior vena cava provide excellent venous drainage and easy fit. Encircling of the venae cavae and their generous mobilization aid in the subsequent exposure of the mitral valve.

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.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
