In Vitro Flow Modelling for Mitral Valve Leakage Quantification [PDF]

, 2009
In this study particle image velocimetry (PIV) is used to measure and visualise the blood flow through a leaking mitral heart valve. The results are compared with the results from Doppler echocardiography and computational fluid dynamics (CFD). Using CAD,

A Misleading Left Atrial Appendage

JACC: Case Reports, 2023
Left atrial appendage collapse is a relatively unusual echocardiographic finding. Although in post-cardiac surgery patients it may be an early sign of cardiac tamponade, and pericardiocentesis should be discussed, a conservative approach may be followed ...

Modified pseudo-elastic approach for modelling cyclic response of biological heart valves [PDF]

, 2016
A modified pseudo-elastic approach is proposed to model cyclic response on biological heart valves. The model takes into account hysteretic effects, in combination with hyperelastic anisotropic behaviour of valve leaflets, allowing reproduction of ...

Isolated double-orifice mitral valve in a young girl

ARYA Atherosclerosis, 2017
BACKGROUND: Double-orifice mitral valve (DOMV) is an extremely rare cardiac malformation. It has been found to be accompanied by congenital anomalies (CAs), however, it can be detected as an isolated anomaly.

Speaking from the heart: a mathematical point of view [PDF]

, 2019
The mechanics associated with a living entity dictates its ability to survive or perish. Similarly, heart valve function relies on its mechanical properties and structural integrity. A compromise in these leads to diseased valve states.

Injectable living marrow stromal cell-based autologous tissue engineered heart valves: first experiences with a one-step intervention in primates [PDF]

, 2017
Aims A living heart valve with regeneration capacity based on autologous cells and minimally invasive implantation technology would represent a substantial improvement upon contemporary heart valve prostheses.

Transseptal BATMAN for High-Risk Valve-in-Ring Procedures

JACC: Case Reports
Valve-in-ring procedures represent a feasible solution for high-risk patients with surgical repair failure. The risk of left ventricular outflow tract obstruction increases the challenge, and transcatheter approaches to prevent it are technically ...
