Quadricuspid aortic valve (QAV) is a rare congenital anomaly characterized by the presence of four cusps instead of the usual three. It is estimated to occur in less than 0.05% of the population, with Type A (...

Transcatheter aortic valve replacement (TAVR) has emerged as an effective therapy for inoperable patients with severe aortic stenosis (AS). However, calcification-induced limited durability restricts its application. Fish swim bladders (FSB), which are resistant to calcific degeneration, offer a viable solution to this challenge. In this study, we developed a new TAVR device using FSB as the valve leaflet. Furthermore, the in vitro durability, in vivo performance, and size selection of this TAVR...

To assess whether retrograde cerebral perfusion reduces neurological injury and mortality in patients undergoing surgery for acute type A aortic dissection.

CONCLUSIONS: The use of prefabricated bovine pericardial grafts represents a promising option for the treatment of native and prosthetic aorto-iliac and infrainguinal infections. The application of this biological graft with a standardized postoperative protocol has been associated with a satisfactory patency and reinfection rate without increased bleeding complications.

CONCLUSION: Although SVAS progression in middle age is quite rare, it can be successfully corrected with detailed and selected surgical procedures.

Aortic root reconstruction during aortic root replacement for a patient with prosthetic valve endocarditis and aortic root abscess can be a difficult procedure with many possible complications. In this video case report, we describe our novel technique using a single bovine pericardial patch that avoids deep stitches or external sutures to support the friable annulus. Compared with more standard methods, this approach has shorter cross-clamp and cardiopulmonary bypass times and is less demanding...
