Undiagnosed mitroflow bioprosthesis deformation causing early structural valve deterioration

, 2017
Bioprosthesis are commonly used in the elderly population. Structural valve deterioration affects the long-term durability. We report an early deterioration of a Mitroflow valve caused by ring deformation and prosthetic leaflet rupture.

Clinical and Echocardiographic Outcomes After Implantation of the ALLEGRA Transcatheter Valve Using the Fully Repositionable IMPERIA Delivery System: One‐Year Results of the EMPIRE I Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The EMPIRE I study assessed the early (30 days) safety and efficacy of a new fully repositionable delivery system (IMPERIA) for the commercially available ALLEGRA transcatheter aortic valve in patients with either severe native aortic stenosis or a degenerated surgical bioprosthesis.

Evaluation of aortic bioprosthesis stenosis by multidetector CT.

, 2012
Because visualization the bioprosthesis leaflets is often hampered by shadowing artifacts from to the metal in the annulus or the struts, visualization and determination of the etiology of bioprosthesis valve dysfunction may be often difficult by ...

Around and Through: Successful Mitral Paravalvular Leakage Closure Using Both Anterograde and Retrograde Approaches

Catheterization and Cardiovascular Interventions, Volume 107, Issue 7, Page 2179-2182, June 1, 2026.
ABSTRACT Paravalvular leak (PVL) is a recognized complication after surgical mitral valve replacement and may cause heart failure, pulmonary hypertension, or hemolysis when moderate or severe. Although redo surgery is the definitive treatment, it carries substantial risk in elderly patients or those with multiple prior cardiac surgeries.

Permanent Pacemaker Implantation Following Transcatheter Aortic Valve Replacement: Incidence, Predictors, and Association With Reduced Ischemic Stroke Risk

Catheterization and Cardiovascular Interventions, Volume 107, Issue 6, Page 2124-2134, May 1, 2026.
ABSTRACT Background Development of conduction abnormalities requiring pacing after transcatheter aortic valve replacement (TAVR) is relatively common. The effects of post‐TAVR permanent pacemaker (PPM) implantation on mortality, ischemic stroke, and cardiovascular outcomes remain incompletely characterized.

EARLY DEGENERATED BIOPROSTHETIC MITRAL VALVE [PDF]

Romanian Journal of Pediatrics, 2014
Mitral valve prolapse (MVP) is fairly common in children, often being randomly found in asymptomatic, as well as in symptomatic patients with conjunctive tissue diseases (CTD). The authors report the case of an 11-yearold girl, diagnosed at the age of 6

Challenging Anticoagulation With Warfarin and Heparin Following Mechanical Mitral Valve Replacement in a Patient With Infective Endocarditis: A Case Report Highlighting Diagnostic Difficulties

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Warfarin remains the cornerstone of anticoagulation therapy following mechanical heart valve replacement. However, challenging anticoagulation responses, resistance to warfarin, and even more rarely to both warfarin and heparin pose significant clinical challenges and complicate management strategies.
