Dynamics of transcatheter heart valves with an in vitro experiment incorporating particle image velocimetry

AIP Advances, 2021
The malfunctioning heart valve will compromise the cardiovascular circulation of the human body. Given that artificial valves can be used to replace a disabled one, a feasible in vitro evaluation system is important before any possible implantation.

Two‐Stage Treatment for Adult Large Patent Ductus Venosus

Annals of Gastroenterological Surgery, EarlyView.
This is the first report of a two‐stage treatment for an adult large PDV involving the first stage surgical angioplasty of the large Arantius' duct and second stage embolization of the formed small Arantius' duct. The two‐stage approach could avoid embolic material migration into the systemic circulation or acute portal hypertension associated with the

Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, Volume 105, Issue 7, Page 1597-1607, June 1, 2025.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

Pressure‐Wire Guided Hybrid Branch Pulmonary Artery Band Placement for Palliation of Single Ventricle and Critical Congenital Cardiac Lesions

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Historically, bilateral pulmonary artery band (PAB) placement was guided by pulmonary blood flow surrogates including systemic blood pressure (BP) and arterial saturation. These metrics alone may result in suboptimal bPAB placement.
