Outcome Measures
Primary Outcomes (1)
The Clinical success - reduction of angina symptoms
The severity of angina is assessed by the Canadian Cardiovascular Society Scale (CCS) class, which ranges from grade I to IV. A higher CCS grade indicates a greater severity of angina.
1-Year after implantation
Secondary Outcomes (3)
Incidence of Treatment-Emergent Adverse Events
1-Year after implantation
Change in potential aerobic capacity and endurance - The six minute walking test (6MWT)
1-Year after implantation
Reducing the severity of angina and it impact on quality of life, as shown by the Seattle Angina Questionnaire.
1-Year after implantation
Study Arms (1)
Coronary Sinus Reducer implantation
Subject after Coronary Sinus Reducer implantation due to chronic disabling refractory angina pectoris (Canadian Cardiovascular Society \[CCS\] classes 2-4) despite maximally tolerated anti-angina medical therapy. All patients were evaluated by the local Heart Team and considered not amenable to percutaneous or surgical revascularization procedures. After the Heart Team evaluation patients were qualified for the procedure or Coronary Sinus Reducer implantation unless they meet one of the exclusion criteria. Initial patient evaluation (prior to device implantation) consists of past medical history, actual clinical assessment with an evaluation of CCS class, Seattle Angina Questionnaire - 7 items (SAQ-7) scores, 6-min walk distance (6-MWT) test, and echocardiography. First, a follow-up visit is scheduled 1 month after the implantation procedure than the follow-up is planned twice a year.
Interventions
Coronary Sinus (CS) Reducer implantation to coronary sinus via the venous system. Coronary Sinus is a balloon-expandable, hourglass-shaped, scaffold implanted percutaneously into the coronary sinus creating a narrowing to delay blood outflow.
Eligibility Criteria
The study population will consist of subjects with chronic disabling refractory angina pectoris (Canadian Cardiovascular Society \[CCS\] classes 2-4) who have not responded to treatment with maximally tolerated anti-angina medical therapy. The local Heart Team will evaluate all patients and determine that they are not suitable for percutaneous or surgical revascularization procedures. Following the Heart Team evaluation, patients who do not have any revascularization options available to them are eligible for the procedure or Coronary Sinus Reducer implantation, unless they meet one of the exclusion criteria.
You may qualify if:
- present of chronic disabling refractory angina pectoris (Canadian Cardiovascular Society \[CCS\] classes 2-4) despite maximally tolerated anti-angina medical therapy
- Heart team evaluation with consideration of ineligibility for percutaneous or surgical revascularization procedures.
You may not qualify if:
- recent acute coronary syndrome (\<3 months),
- recent coronary revascularization (\<3 months)
- a mean right atrial pressure higher than 15 mm Hg
- coronary sinus proximal diameter \<10mm and \>14mm
- life expectancy under 12 months,
- advanced heart failure (New York Heart Association \[NYHA\] Classification - classes 3-4),
- potential implantable cardiac resynchronization therapy defibrillator (CRT-D) implantation candidate.
