  • Adult, Older adult

Who may be able to join

  • Mitral stenosis (MS)

About this study

Official title: Outcome of Preservation of Mitral Valve Leaflets During Mitral Replacement

Are there differences in outcome of mitral valve replacement with preservation of mitral apparatus among rheumatic and/or ischemic mitral lesions?.

Mitral valve replacement with preservation of leaflets, and added coronary artery-bypass surgery, when indicated, is it a feasible and reproducible procedure?.

The study was designed to compare outcome after prosthetic mitral replacement with preservation of mitral apparatus for rheumatic valve disease with outcome of replacement for ischemic myocardium and mitral valve disease, The outcomes will be guided by clinical assessment. and echo-cardiograph.

Read the detailed description

Objectives: The aim is to compare outcome of modified preservation of mitral valve apparatus during prosthetic mitral replacement for rheumatic versus myocardial ischemia \&mitral valve disease.

Methods ;This prospective cross-sectional comparative study will include 50 patients with isolated rheumatic mitral valve disease (group A) and 50 patients with mitral disease and myocardial ischemia (group B), surgery is expected to be performed between 2017 and 2020 at one center. All patients will have modified preservation of mitral apparatus during prosthetic mitral replacement. Additionally, group B patients will have bypass grafts to left anterior descending and/or posterior descending / right coronary artery. Data will be collected and analyzed.

The Institutional Review Board (IRB), Ethics Committee (EC)-approval and consent of each patient were obtained.

Criteria for inclusion of patients and exclusion of others were determined according to the guide lines.

Statistical analysis::

Qualitative variables and their association among both groups were studied by applying Chi-square test and Fisher Exact test. Quantitative variables among both groups were compared by applying independent samples t-test. P < 0.05 values mean statistically-significant results.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Smoking index

    Number of Packs every day X number of years of smoking= Pack.year,

    Measured: One week before surgery(or during first clinical visit) .

  2. Age and gender for each participant

    Males above 40 years and Females above 45 years need pre-operative coronary angio-graph

    Measured: One week before surgery .

  3. For each participant: pathological:type of mitral valve lesion

    severe stenosis with mitral area < 1 cm square, severe regurgitation, or mixed lesions

    Measured: Seven days before surgery .

  4. For each participant: etiological :type of mitral valve lesion

    Rheumatic: distorted thickened leaflets,thickened fibrosed chordae

    Measured: Seven days before surgery .

  5. For each participant: etiological :type of mitral valve lesion

    Rheumatic: distorted thickened leaflets,thickened fibrosed chordae or ischemic incompetence

    Measured: Seven days before surgery- echo-cardiograph.

  6. For each participant:, assessing sub-valvular apparatus

    Thickened chordae, ruptured chordae, ischemia of papillary muscles or lateral ventricular wall.

    Measured: One week before surgery. with Echo-cardiograph.

  7. Abascal echo-cardiographic mitral valve score (Wilkins score)

    :if score is 8 or less it is good for balloon valvo-plasty, if > 8 surgery is recommended ( leaflet mobility, thickness and calcification. Fourthly, sub-valvular thickening., higher scores = more deterioration

    Measured: One week before surgery.with Echo-cardiograph

  8. left ventricular wall motion abnormality

    hypokinesia, Akinesia, Dyskinesia of certain segment(s)

    Measured: one week before surgery - with an echo-cardiograph

  9. Number of participants with Signs of left ventricular dysfunction

    low ejection fraction <52%, low stroke volume< 70 ml, low cardiac output <5 litres per minute

    Measured: seven days before surgery echo-cardiograph examination

  10. Number of participants with pre-operative coronary artery disease

    Expected on clinical bases and .proved by Echo-cardiograph-findings

    Measured: seven days before surgery, coronary angio-graph

  11. Number of participants with pre-operative ischemic complications

    left ventricular thrombi, septal and left ventricular wall thickness in mm .

    Measured: seven days before surgery echo-cardiograph examination

  12. Assessment of any evolving new prosthetic valve dysfunction

    Left atrioventricular outflow stenosis, prosthetic dysfunction due to preservation of valve apparatus

    Measured: intra-operative trans-esophageal echo-cardiograph examination

  13. Change in post-operative left ventricular functions

    : Low Fractional Shortening < 28% , Ejection fraction < 40%,, increased left ventricular dimensions and volume

    Measured: 5 days post-operatively and end of 6th and 12 months after surgery with Echo-Cardiograph

  14. Change of Prosthetic mitral valve functions

    Development of para-valvular leak or central jet of regurgitation or stuck valve by a thrombus

    Measured: Monthly through study completion up to 12 months after surgery..... with Echo-cardiograph

Secondary outcomes (3)
  1. changes on Clinical examination

    local and general Examination,: a new murmur, evolving heart failure

    Measured: Monthly up to 12 months after surgery)

  2. Changes in Results of Prothrombin time, concentration and.International normalized ratio

    Adjust dose of oral anticoagulant.( between double and half to three times the control) Dose usually ranges between 1 and 11 mg warfarin tablet daily.

    Measured: .Monthly through study completion up to 12 months.

  3. Mortality and Morbidity

    cause of mortality, type of morbidity: wound infection, hypertrophied scar, Kiloid Formation

    Measured: Monthly through study completion up to 12 months.

The record says: finished, as of the sponsor's last update on 30 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Smoking index (time frame: One week before surgery(or during first clinical visit) .). The study lists 14 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jun 2022.
