Modeling of Hemodynamics in a Vascular Bioprosthesis

Mathematical Biology and Bioinformatics, 2021
The study of blood flow in vascular bioprostheses is a rather complicated task, since the shape of the inner surface of the bioprosthesis is variable, due to xenogenic origin. Because of this, vortex zones can occur inside the vascular bioprosthesis. In addition, the flow structure may contain sections where the flow velocity is abnormally high.

In Vitro Evaluation of Biomaterials for Heart Valve Prosthesis: High Hydrostatic and Enzymatic Treatments as Alternative for Bio‐Derived Materials

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 6, June 2025.
ABSTRACT Various biomaterials are currently used in clinical settings for heart valve repair and replacement. However, the optimal tissue preparation technique remains elusive. In this study, a non‐crosslinked tissue obtained from bovine pericardium, developed by Adeka Corporation, was compared with three commercially‐available tissues: two fixed ...

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‐

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.

Transcatheter Tricuspid Valve-in-Valve Replacement Using a J-Valve System for a Failed Tricuspid Bioprosthesis

Case Reports in Cardiology, 2022
Background. Redo operation for failed tricuspid bioprosthetic valves is associated with high morbidity and mortality. Transcatheter tricuspid valve-in-valve implantation has become an acceptable option for high-risk patients with a failed tricuspid ...

First Experience With a Novel Self‐Expandable Valve for Mitral Annular Calcification Guided by Three‐Dimensional Printing

Catheterization and Cardiovascular Interventions, Volume 105, Issue 4, Page 855-860, March 1, 2025.
ABSTRACT Transcatheter mitral valve replacement (TMVR) may emerge as a surgical alternative for high‐risk patients with severe mitral annular calcification (MAC), yet several questions remain to be addressed. We present the case of a 67‐year‐old high‐risk female patient with severe MAC (MAC score = 8) and mitral stenosis (effective orifice area = 121.3

Noninvasive diagnosis of complications of the mitral bioprosthesis

The Journal of Thoracic and Cardiovascular Surgery, 1976
The echophonocardiographic diagnoses of valvular and paravalvular insufficiency, calcific stenosis, and thrombolic occlusion of the stent-mounted aortic homograft or heterograft in the mitral position are described. Paravalvular and valvular insufficiency were associated with apical systolic murmurs which decreased in intensity after amyl nitrite ...

Noninvasive Assessment of Coronary Artery Disease: Recent Techniques, Diagnostic Accuracy, and Clinical Implications for Modern Cardiology–A Narrative Review

Health Science Reports, Volume 8, Issue 3, March 2025.
ABSTRACT Background and Aims Coronary artery disease (CAD), a leading cause of death globally, is among the most commonly diagnosed manifestations of heart disease. Although invasive coronary angiography (ICA) remains the “gold standard” to detect CAD, it is accompanied by several limitations.

Left Bundle Branch Pacing in a Pediatric Patient With Tricuspid Valve Replacement for a Complex Ebstein Anomaly

Annals of Noninvasive Electrocardiology, Volume 30, Issue 2, March 2025.
This paper presents a unique case of successful implementation of left bundle branch pacing (LBBP) in a pediatric patient with third‐degree atrioventricular block following tricuspid valve replacement for a complex Ebstein anomaly. The procedure was performed under real‐time recording technique, and resulted in the resolution of the patient's symptoms.
