Overview

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.

Eligibility

Inclusion Criteria:

  1. present of chronic disabling refractory angina pectoris (Canadian Cardiovascular Society [CCS] classes 2-4) despite maximally tolerated anti-angina medical therapy
  2. Heart team evaluation with consideration of ineligibility for percutaneous or surgical revascularization procedures.

Exclusion Criteria:

  1. recent acute coronary syndrome (<3 months),
  2. recent coronary revascularization (<3 months)
  3. a mean right atrial pressure higher than 15 mm Hg
  4. coronary sinus proximal diameter <10mm and >14mm
  5. life expectancy under 12 months,
  6. advanced heart failure (New York Heart Association [NYHA] Classification - classes 3-4),
  7. potential implantable cardiac resynchronization therapy defibrillator (CRT-D) implantation candidate.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
