Transcatheter Valve-in-Valve Implantation for Failed Surgical Bioprosthetic Valves.
Summary of "Transcatheter Valve-in-Valve Implantation for Failed Surgical Bioprosthetic Valves."
When bioprosthetic cardiac valves fail, reoperative valve replacement carries a higher risk of morbidity and mortality compared with initial valve replacement. Transcatheter heart valve implantation may be a viable alternative to surgical aortic valve replacement for high-risk patients with native aortic stenosis, and valve-in-valve (V-in-V) implantation has been successfully performed for failed surgical bioprostheses in the aortic, mitral, pulmonic, and tricuspid positions. Despite some core similarities to transcatheter therapy of native valve disease, V-in-V therapy poses unique clinical and anatomic challenges. In this paper, we review the challenges, selection criteria, techniques, and outcomes of V-in-V implantation.

Medical and Biotech [MESH] Definitions
Heart Valve Prolapse
Downward displacement of any one of the HEART VALVES from its normal position. This usually results in failed valve closure.
Cardiac Valve Annuloplasty
A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annuli of HEART VALVES. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
Aortopulmonary Septal Defect
A developmental abnormality in which the spiral (aortopulmonary) septum failed to completely divide the TRUNCUS ARTERIOSUS into ASCENDING AORTA and PULMONARY ARTERY. This abnormal communication between the two major vessels usually lies above their respective valves (AORTIC VALVE; PULMONARY VALVE).
Heart Valve Prosthesis Implantation
Surgical insertion of synthetic material to repair injured or diseased heart valves.
Mitral Valve Annuloplasty
A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annulus of the MITRAL VALVE. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
