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.

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

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Males and females aged 20 years or older
  • NYHA(New York Heart Association) Class Ⅱ to Ⅳ in spite of optimal medical treatment. (For optimal medical treatment, β-blocker or diuretic such as calcium antagonists should be given for at least 3 months.)
  • Patients with left ventricular effusion gradient (LVOT) greater than (1) 30 mmHg at rest or (2) at least 50 mmHg at physiological exercise/dobutamine administration/balsalva manuver. (The pressure difference due to the left ventricle drain must be the proximal mitral valve-septal contact by the systolic motion of mitral valve (SAM).)
  • Patients who voluntarily decide to participate in this clinical trial and provide written informed consent.
  • Patients who are able to understand and follow instructions and participate for the entire duration of the clinical trial.

Exclusion Criteria:

  • Target area wall thickness ≤15mm
  • LV ejection fraction ≤40%
  • Subjects who have unsuitable septal vein and coronary sinus anatomy by cardiac CT or venogram
  • Conduction disturbance; LBBB or RBBB
  • Advanced AV block without permanent pacemaker
  • Subjects who have experience in performing vascular stent procedures (PCI) or CABG on coronary arteries close to the coronary sinus within 3 months.
  • Severe pulmonary HTN ≥70mmHg
  • Patients who have cardiogenic shock and those who have an expected life expectancy of 12 months or less.
  • Patients with other valve diseases (companion disease) that require surgical treatment (in this case, Systolic motion of the mitral valve (SAM) caused by systolic myocardia is not considered a companion disease).
  • Patients who are pregnant, or lactating, or plan pregnacy during the clinical trials
  • Patients who are participated in other clinical trials within 1 month of enrollment
  • Patients who are deemed not to be eligible in this study by physician's discretion
