This case report shows a valve in valve procedure in pulmonary position of a 19-year-old male with a repaired Tetralogy of Fallot. After initial correction, a Mitroflow 23 mm bioprosthetic valve was implanted in pulmonary position. Nine years later severe degeneration of the valve occurred.

Background: Valve-in-valve (ViV) transcatheter aortic valve replacement is indicated in patients undergoing repeat intervention for degenerative aortic valve bioprostheses. Patients with internally stented valves (ie, Mitroflow and Trifecta) are at high risk for coronary artery obstruction during ViV procedures because of valve design, as the leaflets are mounted outside the valve stent.
Objectives: The aim of this study was to compare the hemodynamic and clinical outcomes of transcatheter aortic valve replacement within internally stented valves (ViV-IS) vs other surgical valves (ViV-OS).
Externally mounted versus internally mounted leaflet aortic bovine pericardial bioprosthesis: meta-analysis.

Department of Cardiac Surgery, University of Michigan, Ann Arbor, MI, USA.
Background: Recent studies reported higher-than-expected rates of early structural valve degeneration (SVD) and/or reoperation of externally mounted leaflet aortic bioprosthesis compared with others. This meta-analysis aims to compare the outcomes of bioprostheses with externally versus internally mounted leaflet design in patients who underwent surgical aortic valve replacement (SAVR).
Methods: MEDLINE and EMBASE were searched through November 2021 to identify comparative studies investigating outcomes following SAVR with either externally or internally mounted leaflet aortic bioprosthesis.
