Clinical Trial Summary

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 .

Description:

Lower Silesia Sinus Reducer Registry is a single-center, single-arm registry including all consecutive patients who were referred to the Cardiac Department of Copper Health Center due to chronic disabling refractory angina pectoris (Canadian Cardiovascular Society [CCS] classes 2-4) despite maximally tolerated anti-angina medical therapy and underwent Coronary Sinus Reducer implantation. 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 met one of the exclusion criteria.

Initial patient evaluation (prior to device implantation) consisted 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 was scheduled 1 month after the implantation procedure.The study will include clinical assessments every six months during an observation period. The primary outcomes will be gathered one year after the implantation of the CS. Nevertheless, clinical follow-up will continue for up to five years after the procedure.

Intervention

Device:
• Coronary Sinus Reducer Implantation
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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	Incidence of Treatment-Emergent Adverse Events	Safety outcomes were defined as procedural final serious complications (perforation, abrupt closure, slow flow or no-reflow, unstable ventricular arrhythmias) and device failure (inability to cross coronary sinus, inability to expand; unplanned relocation of the device)	1-Year after implantation
Secondary	Change in potential aerobic capacity and endurance - The six minute walking test (6MWT)	Change in subjects aerobic capacity and endurance will be assessed using The six minute walking test (6 MWT)- The longer the distance covered, the better the exercise tolerance	1-Year after implantation
Secondary	Reducing the severity of angina and it impact on quality of life, as shown by the Seattle Angina Questionnaire.	Potential physical and quality of life limitations will be assessed using Seattle Angina Questionnaire-7 (SAQ-7). Summary score can best be understood by categorizing the scores into ranges: 0 to 24 represents poor health status, 25 to 49 as fair, 50 to 74 as good, and 75 to 100 as excellent.	1-Year after implantation
