“Use of Snare Catheter Technique in Transcatheter Aortic Valve Replacement With Self‐Expandable Valve: Expert Review”

Catheterization and Cardiovascular Interventions, Volume 105, Issue 5, Page 981-989, April 1, 2025.
ABSTRACT The use of the snare catheter (SC) technique has been described in the field of interventional cardiology, in particular in the retrieval of a lost device, for example, a dislodged coronary stent, broken coronary wire, and so forth. In the transcatheter aortic valve replacement (TAVR) procedure, some cases have been observed where the anatomy ...

Elastic Recoil and Deployment Asymmetry of the Transcatheter Heart Valve in Bicuspid Versus Tricuspid Anatomy

Catheterization and Cardiovascular Interventions, Volume 105, Issue 5, Page 1032-1041, April 1, 2025.
ABSTRACT Background Data supporting the use of transcatheter aortic valve replacement (TAVR) for bicuspid aortic valve (BAV) is limited compared to tricuspid aortic valve (TAV) anatomy, as the BAV anatomy poses unique challenges to prosthesis expansion and symmetric deployment. Aims We aim to compare the acute recoil and asymmetry of the SAPIEN‐3 valve

Long‐Term Bioprosthetic Valve Durability After Transcatheter Aortic Valve Replacement With Supra‐Annular Self‐Expanding Versus Intra‐Annular Balloon‐Expandable Valves in Patients With a Small Aortic Annulus

Catheterization and Cardiovascular Interventions, Volume 105, Issue 5, Page 990-997, April 1, 2025.
ABSTRACT Background The long‐term valve durability of supra‐annular self‐expanding valves (SEV) and intra‐annular balloon‐expandable valves (BEV) in patients with small aortic annuli remains unexplored. Aims This study aimed to determine the long‐term bioprosthetic valve durability with SEV versus BEV in patients with small aortic annuli.

Echocardiographic changes after aortic valve replacement: Does the failure rate of mitral valve change?

ARYA Atherosclerosis, 2015
BACKGROUND: Since some degrees of functional mitral regurgitation (MR) may be seen in patients who are candidate for undergoing isolated aortic valve replacement (AVR), determining the effectiveness of AVR surgery on MR rate improvement can be effective ...

Long-term Mortality Predictors in Patients with Small Aortic Annulus Undergoing Aortic Valve Replacement with a 19- or 21-mm Bioprosthesis

Brazilian Journal of Cardiovascular Surgery
Introduction: Replacement of the aortic valve in patients with a small aortic annulus is associated with increased morbidity and mortality. A prosthesis-patient mismatch is one of the main problems associated with failed valves in this patient population.

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‐

Prevalence of Aspirin Resistance in Patients with Transcatheter Pulmonary Valve Replacement

Catheterization and Cardiovascular Interventions, Volume 105, Issue 5, Page 1230-1235, April 1, 2025.
ABSTRACT Background Congenital heart disease (CHD) patients with pulmonary valve failure may undergo transcatheter pulmonary valve replacement (TPVR). Aspirin is often prescribed as long‐term therapy after TPVR to prevent thromboembolic events (TE). Aims We aimed to examine the prevalence of aspirin resistance within the CHD TPVR population.

Infective Endocarditis Caused by Abiotrophia defectiva: A Unique Case Complicated by Mitral Valve Perforation

Clinical Case Reports, Volume 13, Issue 4, April 2025.
ABSTRACT Abiotrophia defectiva, a nutritionally variant streptococcus, represents a rare yet serious cause of infective endocarditis (IE), accounting for 1%–2% of the total IE cases. It affects native valves in 10% of patients, and it is implicated in catastrophic complications.
