Prosthesis-patient mismatch (PPM) occurs when an implanted prosthetic valve is undersized for the patient’s body, impairing valve hemodynamics. 2 Although this concern may be observed in patients ...

Objectives Age may modify the impact of prosthesis–patient mismatch (PPM) on outcomes after aortic valve replacement (AVR), as physical functioning decreases with age, and comorbidities become more ...

Background Afterload mismatch (AM) refers to high-gradient (mean gradient ≥40 mm Hg) severe aortic stenosis (AS) with reduced left ventricular ejection fraction (LVEF <50%) that is hypothesised to ...

Background: To predict the occurrence of valve prosthesis–patient mismatch (VP–PM) after aortic valve replacement (AVR), the surgeon needs to estimate the postoperative effective orifice area index ...

NEW YORK, April 9, 2025 /PRNewswire/ -- Geraldine Ong, MD, MSc, an esteemed cardiologist and clinical investigator specializing in in the diagnosis and management of aortic and aortic valve diseases ...

WASHINGTON, DC—Updated data from the SMART trial show that supra-annular self-expanding valves yield similar clinical outcomes as balloon-expandable valves at 2 years, but with less risk of ...

Background Valve-related haemolysis is a known complication following prosthetic valve surgery. Haemolysis after transcatheter aortic valve implantation (TAVI) has been reported in some studies, all ...

Abstract. Background: Prosthesis-patient mismatch (PPM) is associated with worse outcomes. Objective: Determine the frequency and evaluate preoperatory variables independently associated with severe ...

Introduction Transcatheter aortic valve implantation (TAVI) is a widely used treatment option as an alternative to surgical aortic valve replacement in patients with severe aortic stenosis (AS) at ...

In this series of 577 patients with severe aortic stenosis (SAS) undergoing aortic valve replacement, the operative mortality was 2-fold higher in women (13%) than in men (7%). However, after ...
