About this study

This is a prospective, single-arm, single-center initial feasibility clinical study enrolling subjects with symptomatic ischemic heart disease due to a de novo coronary bifurcation lesion. The objective is to obtain initial insights into the clinical safety of the device-specific aspects of the procedure; whether the device can be successfully delivered and implanted; whether there are any operator technique challenges with device use; human factors; clinical safety of the device and whether the device performs in accordance with its intended purpose.

All enrolled subjects will be treated with the study device during the index procedure and followed after treatment to assess procedural success, clinical safety, and device performance. Follow-up is conducted through 3 years.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Be 21 years of age or older. Have symptomatic ischemic heart disease or objective evidence of reduced blood flow to the heart.

Be eligible for PCI, also known as coronary stenting. Have a new coronary artery narrowing involving a branch point that meets the study's angiographic requirements.

Be willing and able to complete study follow-up. Be able to provide written informed consent. If able to become pregnant, have a negative pregnancy test before the procedure and agree not to become pregnant or breastfeed for 1 year.

Exclusion criteria

Are currently participating in another investigational drug or device study that could interfere with this study.

Had a coronary intervention within 30 days before the planned study procedure. Need a planned additional coronary procedure soon after the study procedure. Had a prior stent placed close to the target lesion. Have a target lesion that requires certain other treatment devices before stent placement, other than balloon angioplasty or intravascular lithotripsy.

Have a serious medical condition that could limit participation, follow-up, or interpretation of the study results.

Have a life expectancy of less than 3 years. Have a condition requiring chronic immunosuppressive therapy or have a severe autoimmune or immunosuppressive condition.

Have significantly reduced heart pumping function. Had a recent acute heart attack, unless certain laboratory values have returned to acceptable levels.

Had a stroke or transient ischemic attack within the past 6 months. Have certain abnormal blood test results, including low white blood cell count, low neutrophil count, low platelet count, or significantly reduced kidney function.

Have active stomach or intestinal bleeding, active peptic ulcer disease, a bleeding disorder, or cannot receive blood transfusions.

Have a known allergy or contraindication to required medications, contrast dye, or study device materials that cannot be adequately managed.

Are pregnant, breastfeeding, or planning to become pregnant within 1 year after the study procedure.

Have coronary anatomy that is not suitable for the study device, as determined during coronary angiography (This may include blood clot in the target lesion, severe vessel tortuosity, severe calcification, certain lesion locations, or other significant disease in the target vessel).

Are unable or unwilling, in the opinion of the study doctor, to comply with the study requirements.

Treatment and study plan

MD-SBA DES System

Device

The MD-SBA DES System is a single use, minimally invasive combination product that consists of a cobalt chromium metal coronary stent, coated with sirolimus in a PEA/BHT matrix, on a rapid exchange (RX) delivery system.

Other names: Percutaneous coronary Intervention (PCI)

Primary outcomes

  1. Procedure Success

    Time frame: Periprocedural

    To determine whether the device can be successfully delivered and implanted, as measured by attainment of <30% final residual stenosis of the target lesion and no in-hospital major adverse cardiac events (MACE).

Secondary outcomes

  1. MACE

    Time frame: 30-days, 6-months, 1-year, 2-years, and 3-years post index procedure

    Percentage of subjects with major adverse cardiac events, defined as cardiac death, myocardial infarction, emergency coronary artery bypass surgery, or clinically driven target lesion revascularization. Components of MACE, including cardiac death and myocardial infarction, may also be summarized.

  2. TVF

    Time frame: 30-days, 6-months, 1-year, 2-years, and 3-years post index procedure

    Percentage of subjects with target vessel failure, defined as cardiac death, target vessel myocardial infarction, or clinically driven target vessel revascularization.

  3. Target Lesion Revascularization of the Side Branch

    Time frame: 30-days, 6-months, 1-year, 2-years, and 3-years post index procedure

    Percentage of subjects requiring repeat treatment of the side branch by percutaneous or surgical methods.

  4. Stent thrombosis

    Time frame: 6-months, 1-year, 2-years, and 3-years post index procedure

    Percentage of subjects with late stent thrombosis.

  5. Acute Success

    Time frame: Index procedure

    Percentage of subjects with successful device delivery and target lesion treatment, including final residual stenosis <30% and adequate side branch flow.

  6. Side Branch Access

    Time frame: Index procedure

    Percentage of subjects with TIMI-3 flow in the side branch and/or need to re-cross the side branch after study device use.

  7. Bleeding / Vascular Complications

    Time frame: Hospital discharge

    Percentage of subjects with bleeding or vascular complications.

  8. Procedure Time

    Time frame: Index procedure

    Duration of the index procedure in minutes

  9. Fluoroscopy Time

    Time frame: Index procedure

    Total fluoroscopy duration during index procedure in minutes

  10. Contrast Volume

    Time frame: Index procedure

    Total volume of contrast media used during index procedure in milliliters
