Aortic Valve Reconstruction with Ozaki Technique
Brazilian Journal of Cardiovascular Surgery, 2021 Modern bioprostheses offer a complete and definitive solution to elderly patients who need aortic valve surgery. Nonetheless, the scenario is more demanding when dealing with younger and less fragile patients. In this setting, any prosthetic aortic valve

Transcatheter Valve Unable to Cure Patient–Prosthesis Mismatch of Mosaic Bioprosthesis
The Thoracic & Cardiovascular Surgeon Reports, 2016 Transcatheter aortic valve implantation (TAVI) has been recently established as a less invasive alternative to conventional aortic valve replacement (CAVR) in patients presenting with expected high procedural risk.

Patient Prosthesis Mismatch After SAVR and TAVR
Frontiers in Cardiovascular Medicine, 2022 Patient-prosthesis mismatch (PPM) remains one out of many factors to be considered during decision-making for the treatment of aortic valve pathologies. The idea of adequate sizing of a prosthetic heart valve was established by Rahimtoola already in 1978.
