Association Between Cardiopulmonary Bypass Weaning Time and Adverse Outcomes in Patients With Aortic Dissection Who Underwent Total Arch Replacement Combined With Stented Elephant Trunk Implantation

February 28, 2026 No Comments

This retrospective single-center study of 475 patients with acute type A aortic dissection undergoing total arch replacement with stented elephant trunk implantation found that prolonged cardiopulmonary bypass (CPB) weaning time was independently associated with increased in-hospital mortality and postoperative stroke. A cutoff of 90 minutes strongly predicted early mortality and reduced short-term survival, though mid-term survival was unaffected.

Cardiopulmonary Bypass Supporting High-Risk PCI and TAVR

Cardiopulmonary Bypass as Safe and Effective Support for Concomitant High-Risk Percutaneous Coronary Intervention and Transcatheter Aortic Valve Replacement

February 28, 2026 No Comments

This study evaluates the safety and effectiveness of cardiopulmonary bypass (CPB) as hemodynamic support during combined high-risk percutaneous coronary intervention (PCI) and transcatheter aortic valve replacement (TAVR). The authors demonstrate that CPB provides stable circulatory support, enabling complete revascularization and valve implantation in complex patients with severe coronary artery disease and aortic stenosis, with acceptable complication rates and favorable procedural outcomes.
