Meta-Analysis: ViV TAVR Shows Fewer Complications, Better Early Survival vs. Redo SAVR in Degenerated Valves
ViV TAVR also shows higher MI, severe patient-prosthesis mismatch
Valve-in-valve transcatheter aortic valve replacement (ViV TAVR) showed a lower incidence of postoperative complications and better early survival, but also a higher rate of myocardial infarction and severe patient-prosthesis mismatch, as compared to redo surgical aortic valve replacement (SAVR) in degenerated bioprosthetic aortic valves, according to a meta-analysis of 12 observational studies released Monday.
