Mitroflow aortic pericardial bioprosthesis — clinical performance☆☆☆ [PDF]

European Journal of Cardio-thoracic Surgery, 2009
Advancing life expectancy with the increased prevalence of aortic valve degenerative disease brings the need for an aortic bioprosthesis with excellent haemodynamic performance and comparable durability. The Mitroflow bioprosthesis has been on the worldwide market, except in the United States, since 1982, while the current model (1991) has only ...

Sutureless aortic bioprosthesis [PDF]

Interactive CardioVascular and Thoracic Surgery, 2017
Aortic valve replacement (AVR) is the treatment of choice for aortic valve disease, with excellent results reported in the short- and long-term follow-up. Due to the increasing number of patient comorbidities and older age, various technical alternatives have been developed such as transcatheter aortic valve implantation and, more recently, sutureless ...

Matryoshka procedure for Valve‐in‐Valve TAVI failure

Clinical Case Reports, 2022
Valve‐in‐valve transcatheter valve implantation (ViV‐TAVI) procedures for deteriorated bioprosthesis are an established therapeutic option for high‐risk patients. The presence of the fixed sewing ring of the bioprosthesis can hamper appropriate expansion

Remote Ischemic Preconditioning Neither Improves Survival nor Reduces Myocardial or Kidney Injury in Patients Undergoing Transcatheter Aortic Valve Implantation (TAVI) [PDF]

, 2020
BACKGROUND: Peri-interventional myocardial injury occurs frequently during transcatheter aortic valve implantation (TAVI). We assessed the effect of remote ischemic preconditioning (RIPC) on myocardial injury, acute kidney injury (AKIN) and 6-month ...

Human aortic bioprosthesis [PDF]

European Journal of Cardio-Thoracic Surgery, 2008
We have read with the greatest interest the paper by Wolfgang A. Goetz et al. entitled Truly stentless molded autologous pericardial aortic valve prosthesis with single point attached commissures in a sheep model [1]. We congratulate the authors on their achievements in the development of valve bioprosthesis.
