Lower Silesia Sinus Reducer Registry
Lower Silesia Sinus Reducer Registry is a , single-center, single-arm registry including patients with chronic disabling refractory angina pectoris (Canadian Cardiovascular Society [CCS] classes 2-4) despite maximally tolerated anti-angina medical therapy who underwent Coronary Sinus Reducer implantation .
- EligibilityCriteria: Inclusion Criteria:  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.  Exclusion Criteria:  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. - HealthyVolunteers: No - Gender: All - MinimumAge: 18 Years - StdAgeList: Adult, Older Adult - StudyPopulation: 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. - SamplingMethod: Non-Probability Sample
