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

Restoration of a Stuck Leaflet

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Severe aortic regurgitation (AR) for a leaflet malfunction after transcatheter aortic valve implantation (TAVI) is a dreadful complication that can lead even to cardiogenic shock. New valve's design has reduced the rate of paravalvular regurgitation, however central regurgitation is still a challenging complication.

Bridging aortic valve surgery to 21st century. what can a surgeon do [PDF]

, 2019
Aortic valve stenosis is the most clinically relevant valvular heart disease in the elderlies. Surgical aortic valve replacement (SAVR) represented, for decades, the standard of care for the treatment of severe aortic stenosis.

Long‐Term Impact of Early Subclinical Leaflet Thrombosis After Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, Volume 105, Issue 5, Page 1161-1170, April 1, 2025.
ABSTRACT Background Hypoattenuated leaflet thickening (HALT) after transcatheter aortic valve implantation (TAVI) detected on multidetector computed tomography (MDCT) is considered leaflet thrombosis. However, its impact on long‐term clinical outcomes remains unclear. This study aimed to investigate the impact of early HALT detection after TAVI on long‐

Normally and abnormally functioning left-sided porcine bioprosthetic valves after long-term implantation in patients: Distinct spectra of histologic and histochemical changes [PDF]

, 1984
This morphologic study (X-ray examination of gross specimens, histologic study and histochemical staining) compares two groups of explanted left-sided biopros-thetic valves: group 1,6 valves with normal cusp function and group II, 10 valves with ...

Percutaneous Pulmonary Valve Implantation In Native Right Ventricular Outflow Tract Using Myval™ Without Pre‐Stenting

Health Science Reports, Volume 8, Issue 4, April 2025.
ABSTRACT Background and Aims Percutaneous pulmonary valve implantation was introduced two decades ago as a low‐risk alternative for patients previously operated with conduits presenting RVOT dysfunction. Recently, Sapien valve was approved for use in the pulmonary position but this valve cannot be used for RVOT larger than 29 mm.

Noncalcific Mechanisms of Bioprosthetic Structural Valve Degeneration

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Bioprosthetic heart valves (BHVs) largely circumvent the need for long‐term anticoagulation compared with mechanical valves but are increasingly susceptible to deterioration and reduced durability with reoperation rates of ≈10% and 30% at 10 and 15 years,
