Recruiting NA Coronary Microvascular Dysfunction

New treatment option for Coronary Microvascular Dysfunction

Official title Self-Expanding Coronary Sinus Reducer for Treatment of Symptomatic Coronary Microvascular Dysfunction (CMD) (SERRA-I Study)

ClinicalTrials.gov ID: NCT06991322

What this study is testing

What it's testing
VahatiCor's Coronary Sinus Reducer (A-FLUX) has been designed to improve angina or angina-like symptoms in patients with CMD. SERRA-I is an early feasibility study that evaluates the safety and clinical performance of the A-FLUX Reducer in this population.

  • Willing and able to sign informed consent.
  • Willing to comply with the specified follow-up evaluations.
  • Mean right atrial pressure ≤15 mmHg.
  • The CS anatomy is suitable for implantation at the Investigator's discretion.
What rules you out
  • Significant obstructive epicardial disease (greater than 50% diameter stenosis) that can be treated with PCI or CABG as determined by Investigator and confirmed by the Central Screening Committee.
  • Recent (less than 30 days before index procedure) troponin or CKMB positive acute coronary syndrome (NSTEMI or STEMI) with evidence of ischemia.

  • NYHA class IV or decompensated HF or hospitalization due to HF during the 90 days before the index procedure.
  • Life-threatening rhythm disorders or any rhythm disorders that would require cardiac resynchronization therapy or lead placement in the coronary sinus.
  • Severe chronic obstructive pulmonary disease (COPD) as indicated by a forced expiratory volume in one second (FEV1) of less than 1.0L or need for home daytime oxygen or regular oral steroids.
  • Severe valvular heart disease (any valve).
  • Moderate (TAPSE\<12) or severe RV dysfunction (TAPSE\<8) by echocardiography.
  • A pacemaker electrode/lead is present in the coronary sinus.

  • Any clinical condition that might interfere with the trial protocol or the subject's ability to be compliant with the trial protocol (e.g., active alcohol or illicit substance use, cognitive decline).
  • Currently enrolled in another investigational device or drug trial that has not reached its primary endpoint or might clinically interfere with the current trial endpoints or procedures.
  • Pregnant or planning pregnancy within the next 12 months (females of reproductive potential must have a negative pregnancy test within 7 days of the procedure).
  • Part of a vulnerable population who, in the investigator's judgment, cannot give Informed Consent for reasons of incapacity, immaturity, adverse personal circumstances, or lack of autonomy.
  • Inability to tolerate dual antiplatelet therapy for 6 months if not on a chronic oral anticoagulant, or inability to tolerate a P2Y12 inhibitor for at least 6 months if on a chronic oral anticoagulant.
