Left Atrial Appendage Closure: A Single-Center Experience in a Population With a High Prevalence of End-Stage Renal Disease.

Background Left atrial appendage closure (LAAC) has emerged as an alternative approach for mitigating thrombotic risk in nonvalvular atrial fibrillation patients. However, existing registries often lack representation of the Hispanic population, motivating this study to elucidate the demographic, clinical, and procedural characteristics, specifically among Hispanic patients undergoing this procedure. Methods Adult patients who underwent percutaneous LAAC between June 2017 and July 2022 at a high-complexity hospital in Bogotá, COL, were included.

Zero-contrast left atrial appendage closure, a feasible alternative for patients with a high risk of contrast-induced nephropathy: Systematic literature review and meta-analysis.

Background: Left atrial appendage closure (LAAC) is an alternative to reduce thrombotic risk in patients with nonvalvular atrial fibrillation. This procedure conventionally requires the use of a contrast agent. A significant proportion of patients who undergo this procedure have chronic kidney disease, with a high risk of contrast-induced nephropathy.

Successful Percutaneous Coronary Intervention in Chronic Total Occlusion after Coronary Perforation.

Coronary chronic total occlusions are challenging lesions with high rates of complications related to percutaneous intervention. We describe a successful angioplasty in a patient with a recent coronary perforation, using multiple techniques, such as stick and swap with Stingray, subintimal transcatheter withdrawal, and investment.
