Transepicardial With Transseptal Autologous CD 133+ Bone Marrow Cell Implantation in Patient Following CABG Surgery

March 16, 2020 updated by: Tri Wisesa Soetisna, MD, MHA, National Cardiovascular Center Harapan Kita Hospital Indonesia

The Effect of Transepicardial Augmentation on Transseptal Autologous CD 133+ Bone Marrow Cell Implantation to Myocardial Perfusion in Patient Following Coronary Artery Bypass Grafting

Heart Failure has several etiologies and one of them is coronary artery disease. Coronary artery bypass grafting (CABG) is one of revascularizations method which has been used for decades in coronary artery disease theraphy. However, data about coronary artery bypass grafting shows that post-CABG patients still have low ejection fraction. For the last decade, there have been a lot of studies about the using of stem cells to increase heart contractility and reverse the heart remodelling process. In this study, we use CD 133+ bone marrow stem cells which has been proved to have higher angiogenesis potential. The stem cells is given during CABG by injection transepicardial and transseptal. The purpose of this study is to determine whether transpicardial and transseptal injection of CD 133+ bone marrow stem cells can improve myocardial perfusion in patient with low ejection fraction following CABG surgery.

Study Overview

Detailed Description

Study sample : patient with low ejection fraction indicated for CABG surgery in NCCHK who fulfill inclusion and exclusion criteria

Sampling method : first we use consecutive method to find subject with male sex and age 40-70. After that, we use simple random sampling to allocate each subject to each group.

Total samples is 13 for each group. To anticipated drop out rate 10%, total sample is 15 for each group.

Intervention and measurement :

Control group will only receive CABG surgery. Study group will receive CBAG surgery and stem cell implantation. Stem cell aspiration will be performed 1 day before CABG procedure. Before aspiration, patients will be given local anesthetic and light sedation. Stem cell will be collected from posterior iliac crest. Total aspirate 190 cc. Stem cell CD133+ will be separated using CliniMACS® Magnetic Separation Device after labelled with Magnetic microbeads - anti CD133 labelling.

Myocardial perfusion reserve index will be measure using MRI. MPRI value will be obtained globally and segmentally in each 16 ventricle segments VEGF plasma level will be measured using sandwich Enzyme-linked Immunosorbent Assay method.

Ejection fraction, left ventricle dimension, and scar size will be measured using MRI.

Quality of life will be measured using Minnesota Living With Heart Failure Questionnaire.

Statistical analysis is done using IBM SPSS Statistics version 21.0 (SPSS inc, Chicago, IL, USA). Numerical data will be presented in either mean/standard deviation or median/min-max depend on distribution of data. Hypothesis test for numeric variable is done using paired/non-paired T test or Mann-Whitney/Wilcoxon depend on normality of data. Normality test is done using Shapiro-Wilk test. Hypothesis test for category varible is done using chi-square or fischer test.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Myocardial Defect Perfusion
Time Frame: Baseline, 6 months
Number of heart wall segments with perfusion defect measured by MRI.
Baseline, 6 months
Left Ventricular Ejection Fraction
Time Frame: Baseline, 6 months
Left ventricular ejection fraction (LVEF) measured by MRI. Normal range of LVEF ranges from 50% to 70%. Borderline LVEF ranges from 41% to 49% Reduced LVEF ranges < 41%
Baseline, 6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Six Minutes Walking Test
Time Frame: Baseline, 6 months
Quality of life will be assessed using Six minutes walking test, to see the changes of six minutes walking test before and after intervention Distances reported for healthy individuals ages 40 yo 85 years range from 400 to 700 m..
Baseline, 6 months
Wall Motion Score Index
Time Frame: Baseline, 6 months

Cardiac wall motion abnormality will be measured using Wall Motion Score Index with MRI. Each myocardial segment is assigned a score from 1 to 4. The 16 segment model of myocardial segmentation is recommended.

A WMSI of 1.0 is considered normokinetic. A WMSI of 1.5 is considered mild hypokinesia A WMSI of 2.0 is considered hypokinesia A WMSI of 2.5 is considered severe hypokinesia A WMSI of 3.0 is considered akinetic.

Baseline, 6 months
Myocardial Scar Size
Time Frame: Baseline, 6 months

Percentage of myocardial scar size proportion measured by MRI to quantify and define the extent/transmurality of scar tissue, the following definitions were used

  1. spatial (circumferential) extent, the number of affected segments
  2. nontransmurality, the number of segmments with a segmental scar score of 1 or 2, and transmurality, the number of segments with a segmental scar score of 3 or 4
  3. total score, summed segmental scar scores per patient divided by 17 (which reflects the damage per patient)
Baseline, 6 months
Vascular Endothelial Growth Factor
Time Frame: Baseline, 6 months
Cytokine that has important role for angiogenesis. Normal range for plasma VEGF is 0-115 pg/ml
Baseline, 6 months
Left Ventricle End Systolic Volume
Time Frame: Baseline, 6 months

Left ventricle end-systolic volume is the volume of blood in a left ventricle at the end of contraction, or systole, and the beginning of filling, or diastole.

Normal LVESV ranges is 37 - 57 mililiters.

Baseline, 6 months
Minnesota Living With Heart Failure Questionnaire
Time Frame: Baseline, 6 months

Quality of life assessed using Minnesota Living With Heart Failure Questionnaire consist of 21 questions, to see the changes before and after intervention.

Minimum score = 0, Maximum score = 105 Higher values represent a worse outcome

Baseline, 6 months
Left Ventricle End Diastolic Volume
Time Frame: Baseline, 6 months

Left ventricle end-diastolic volume is the volume of blood in the left ventricle at end load or filling in (diastole) or the amount of blood in the ventricle just before systole.

Normal ranges of LVEDV is 121 - 163 mililiters

Baseline, 6 months
