The efficacy and safety of coronary sinus reducer in refractory angina: a systematic review and meta-analysis.

ABSTRACT:

Background

Refractory angina is a challenging medical disorder associated with continuous anginal symptoms that do not respond to medical treatments or revascularization interventions. Coronary sinus reducer (CSR) has been introduced as a promising treatment option for patients with refractory angina. However, the avaliable evidence regarding the exact role of CSR in managing refractory angina is still inconclusive and limited by several factors, such as small sample size studies, and short follow up periods. Therefore, we conducted this study to evaluate the effectiveness and safety of CSR for managing patients with refractory angina.

Methods

An extensive digital search of several databases encompassing PubMed, Scopus, Web of Science, and Cochrane Library was conducted from
