Long-term survival following aortic valve replacement : the influence of age, prosthesis-patient mismatch and indexed effective orifice area [PDF]

, 2017
Background: Prosthesis-patient mismatch (PPM) has been linked to reduced long-term survival after aortic valve replacement. We studied the influence of age, PPM and indexed effective orifice area (iEOA) in this setting. Methods Patients (n=586) subjected

Clinical Outcomes Post‐Transcatheter Aortic Valve Replacement in Patients With Hypertrophic Obstructive Cardiomyopathy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Patients with hypertrophic obstructive cardiomyopathy (HOCM) were excluded from all major trials for transcatheter aortic valve replacement (TAVR). “Suicide left ventricle” occurring after TAVR is postulated to occur as a result of chronic pressure overload from fixed obstruction that is acutely relieved after the valve deployment ...

In vitro comparison of aortic heart valve prostheses

The Journal of Thoracic and Cardiovascular Surgery, 1988
The hydrodynamic performance of a series of mechanical heart valve prostheses is measured in the aortic position. All experiments are performed in an electrohydraulic, computer-controlled pulse duplicator simulating the left side of the human circulatory system.

Transendocardial injection of expanded autologous CD34+ cells after myocardial infarction: Design of the EXCELLENT trial

ESC Heart Failure, Volume 12, Issue 2, Page 1455-1463, April 2025.
Abstract Aims The extent of irreversible cardiomyocyte necrosis after acute myocardial infarction (AMI) is a major determinant of residual left ventricular (LV) function and clinical outcome. Cell therapy based on CD34+ cells has emerged as an option to help repair the myocardium and to improve outcomes.
