Comparison of Complete Versus Incomplete Percutaneous Revascularization in Patients With Chronic Total Occlusion: A Systematic Review and Meta-Analysis.

The optimal extent of revascularization in patients with chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI) remains debated. This meta-analysis aimed to compare the clinical outcomes of complete versus incomplete revascularization in CTO patients. A systematic search of EMBASE, PubMed, and Web of Science was conducted up to July 6, 2024.

Evaluating the Efficacy of Coronary Sinus Reducer Implantation in the Management of Refractory Angina: A Systematic Review and Meta-Analysis.

The coronary sinus reducer (CSR), a minimally invasive device, has emerged as a promising alternative for improving myocardial perfusion in these patients. This meta-analysis evaluated the effectiveness of CSR implantation in patients with refractory angina. A comprehensive search of PubMed, EMBASE, and Web of Science databases identified 10 relevant studies with a pooled sample size of 799 patients.
