Pulsed Cavitational Ultrasound Softening

JACC: Basic to Translational Science, 2017
The authors propose a novel noninvasive therapeutic approach for degenerative calcified bioprosthetic heart valves based on pulsed cavitational ultrasound (PCU) to improve the valvular function by remotely softening calcified stiff cusps. This study aims

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.

Benefits and Pitfalls of the Perceval Sutureless Bioprosthesis [PDF]

Frontiers in Cardiovascular Medicine, 2022
Objective: To highlight the main target points covered by clinical studies on the Perceval sutureless valve for surgical aortic valve replacement (SAVR) and raise a point of discussion for further expansion of its use when compared with stented bioprostheses (SB) and transcatheter aortic valve replacement (TAVR).Methods: We reviewed clinical trials and

Experimental Study and Early Clinical Application Of a Sutureless Aortic Bioprosthesis

Brazilian Journal of Cardiovascular Surgery, 2015
INTRODUCTION: The conventional aortic valve replacement is the treatment of choice for symptomatic severe aortic stenosis. Transcatheter technique is a viable alternative with promising results for inoperable patients.

European experience with the Mosaic bioprosthesis [PDF]

The Journal of Thoracic and Cardiovascular Surgery, 2002
The purpose of this study was to prospectively evaluate the clinical and hemodynamic performance of the Mosaic bioprosthesis (Medtronic, Inc, Minneapolis, Minn).The stented porcine bioprosthesis combines the amino-oleic acid antimineralization treatment and the zero-pressure differential fixation technique for improved tissue durability.

O conduto valvulado bovino contegra, um biomaterial para o tratamento cirúrgico de cardiopatias congênitas The contegra valved bovine conduit: a biomaterial for the surgical treatment of congenital heart defects

Arquivos Brasileiros de Cardiologia, 2012
O Contegra, um enxerto de veia jugular bovina, tem sido amplamente utilizado como biomaterial de preferência no tratamento cirúrgico das cardiopatias congênitas, especialmente como um conduto para a reconstrução da via de saída ventricular direita.

Early calcific degeneration of the St. Jude Medical Epic aortic bioprosthesis

Clinical Case Reports, 2020
This report highlights the need for close surveillance of bioprosthetic valves. Unaccountable degeneration of bioprosthetic valves can develop early after implantation and usually requires replacing the failed valve with a mechanical prosthesis.

Aneurysmal Degeneration of a Bioprosthesis

Kardiologiia, 2018
We present a clinical case of successful correction of aneurismatic dilatation of the anastomosis zone after allotransplant implantation. In 2004 this patient underwent implantation of an arterial allotransplant of "complex architectonics" because of trauma of the iliofemoral arterial segment.

Abdominal wall repair with acellular bovine pericardial membranes - Part I - Clinical and radiological findings [PDF]

Revista Brasileira de Cirurgia Plástica
Introduction: Reducing recurrence rates significantly, the use of biomaterials as “reinforcement meshes” in the repair of different abdominal wall defects has become an almost mandatory routine for the success of these repairs.

The importance of the use of bovine pericardium for surgical reconstructions: a systematic review

Revista Médica de Minas Gerais, 2022
Introduction: The use of bovine pericardium started in 1972 in cardiovascular surgeries. From the evolution of tissue engineering with care in the preparation of the material, minimizing the risk of rejection and facilitating the use for various types
